life on earth are the most valuable things money can not buy, jewelry-for-not go back. life only once, should not renewable and will not re-come. students, and your life has just begun blooming flower, you are prosperous home sustenance, development of the chinese nation are the hope of; your future offspring transmission of both task and maintenance obligations of parents. therefore, you have to cherish life and take care of life, for themselves and for parents, good for homeland alive.
life for each person only once, no life, everything is no-go. therefore, we must firmly embrace the "yes to life, safety first" awareness of construction safety of our campus so that students can grow up healthily.
campus safety relates to our lives and learning potential safety problems have as many as 20 kinds, including traffic accidents, poisoning, fire fire, drowning, sports injury and so on. these are at times a threat to the healthy growth of young students. according to statistics, every year our country has around 16,000 unnatural deaths in the primary, elementary and middle school students because of safety accidents, food poisoning, drowning and other deaths, the average has more than 40 people every day, that is to say every day there will be a class of students at "disappeared." so we not only have safety awareness, and more importantly, prevention awareness and preventive measures. study at daily life, we should note the following:
one, pay attention to safety recess activity. want the students up and down stairs in an orderly manner and must not hurriedly up and down, up and down the stairs right to cultivate the good habit of walking to prevent accidents on campus crowded stampede. rainy at our school buildings and office building corridor, staircase, will be very slippery, please the whole student must light when walking at the foot walk. everyone should pay attention to civilization recess breaks should not chased noisy.
2, it is necessary to pay attention to traffic safety. we must strictly comply with rules of the road, without people to ride, not red light running, horse way to go before crosswalks, it is necessary to take the initiative to avoid motor vehicles. not want to develop the habit of school by bike.
3, pay attention to food safety. not to buy "three noes" of food; we should not be at the school gate and street stalls mobile buy snacks, to prevent food poisoning. to learn how to protect themselves, take care of themselves, pay attention not to overeating, try eating less food cold.
4, it is necessary to pay attention to sports safety. on physical education and extra-curricular activities to prepare before the warming-up, attention should be paid to exercise when not to dramatic collision, so as not to be knocked down or fall.
5, it is necessary to pay attention to internet security. network is a very good learning tool, we can use it to gather information, broaden our horizon. but the network also has a lot of harm, if unhealthy internet browsing web pages, or indulge in unrestrained virtual space, then it will affect our physical and mental health.
6 students for their own actions but also have safety awareness. student encountered at the contradictions between, we want a calm, rational, should not substitute for reasoning with fists, give themselves and their classmates bring about adverse effects. conflict with the people must bear in mind: the broader picture.
teacher and fellow students, only one person's life. a collision, a wrestling are probably the lives of vulnerable people's hard to imagine the harm caused. therefore want to protect their own safety, we comply with the minimum required, the most simple rules and order. let us bear in mind: human life, safety first! let us work together to create a harmonious campus, campus safety!

每当人们谈到内蒙古都会想到辽阔的草原，是的，内蒙古的草原面积占全国总草原面积的1/4。成群的羊儿，牛儿和马儿生活在这片无边无际的草原上，是它们养育了世世代代的草原儿女，因此，草原也被赞颂为“生命的摇篮”。我们的家乡有两大世界著名的草原——呼伦贝尔大草原和锡林郭勒大草原。蒙古族是一个勇敢、热情、好客的民族，如果你去到牧民的家里，无论你来自哪儿，热情的牧民都会用烤全羊和奶茶款待你，同时，你还可以欣赏到优美的蒙古族歌舞。蒙古族人民天生能歌善舞，这一点儿也不夸张，在你踏上草原的那一刻，你就会发现这确实是一片歌舞的海洋。

Good evening, everyone. My name is WangHaili. I am an outgoing girl who likes reading and traveling. It’s really my great honor to stand here and give everyone a short speech.
People say, youth is fire which is ignited by passion. People say, youth is a chapter of the poem which is written by stories. The color of youth is bright and we make most use of our ardor to draw the scenes to the canvas of painting. But we may be confused and lose our direction in the youth time. Under this, youth slips away. Roman Roland says, life doesn’t issue return ticket and can never come back once sets out. So we should seize the short youth time and try our best to pursue our ideal. Do what should we do and let our youth without regret.
When we refer to ideal, we will realize the importance of ideal. Ideal is the beacon,. Without ideal, we will lose the firm direction. Without direction, we will lose our life. According to this, every one of us should establish our own ideal .so that we have the direction of straggle to the future. Tolstoy tells us, we should have the life objective from the whole life to the second. So we should cherish every moment and form our systematic objective. Youth is the prime time. We have strong body and energy and can sense the meaning of life under the guide of ideal.
Zoos should be banned.
Nowadays, lots of people start to realize that zoos are not a good place for animals. People need zoos because it is an easy way to close the animals and also because it's convenient for people to observe them. However, zoos are in fact a cruel place for animals. Animals should live in their natural habitat. An animal's natural instinct is to run and to hunt. But that's not for animals kept in zoos. Everyday, people feed them. They've never been taught how to hunt for food and will gradually lose their natures. That will be quite cruel for a animal, especially for wild animals such as tigers and lions. You can often find in zoos that a tiger kept in cage has a loose expression in its face.We set animals in zoos and therefore feel that they won't meet danger and may be able to protect them from dying out. This may be just a excuse we find for ourselves to make animals in cages just as entertainment. We always say animals are our friends, then why we put our friends in cages?
My favourite animal is tortoise. Tortoise walk not fast. But I like the tortoise. Why? Because, tortoise is a cute animal. It have a short tail and a four short foot. It have a little head and a hard shell. They are forty-five little and cute tortoise in My home. They like to play in the water. When they afraid some thing. They wall run fast. They like to eat the fish. I often buy some small fish to them to eat. They can catch the fish fast. First, they fake(假) sleep. When the fish swim near they mouth. They catch the fish fast and bit the fish head. So, the fish die. They can eat the fish. In winter. They like to sleep in the sand. When they sleep, they don’t eat any food.Because they wall hibernation. But, when they are thirsty. They come out of the sand. So, we must give water to them to drink.
I love the tortoise. I hate the eagle. Because, the eagle often eat the tortoise with it sharp mouth.My favourite animal is tortoise.

my favorite book is . have you read it before?
As everyone knows,English is very important today.It has been used everywhere in the world.It has become the most common language on Internet and for international trade. If we can speak English well,we will have more chance to succeed.Because more and more people have taken notice of it,the number of the people who go to learn English has increased at a high speed.
But for myself,I learn English not only because of its importance and its usefulness,but also because of my love for it.When I learn English, I can feel a different way of thinking which gives me more room to touch the world.When I read English novels,I can feel the pleasure from the book which is different from reading the translation.When I speak English, I can feel the confident from my words.When I write English,I can see the beauty which is not the same as our Chinese...
I love English,it gives me a colorful dream.I hope I can travel around the world one day. With my good English, I can make friends with many people from different contries.I can see many places of GREat interests.I dream that I can go to London,because it is the birth place of English.
Dear classmates,
Every one of us, rich or poor, should at least have one or two good friends. My friends will listen to me when I want to speak, will wipe my eyes when I cry, will take care of me when I am sick, and my friends will go together with me side by side through this journey of life.
As students, we could share more time with our friends. The friendship in our young hearts is pure, fresh and simple. I often feel very lucky to have a lot of good friends. Especially when I had Justin as one of my best friends. Justin was my English teacher from the USA. I met him in 1996 when I was a student who could only speak very little English. Justin was a vivid young man with a bright smile on his face, and he always had his special way to make the class active and attractive. He taught us English by telling stories, playing games, singing songs, and even dancing. I could still remember very clearly that one afternoon when we fin-ished our class, we went to some other classes to sing songs for them, just like what people do in the states on Christmas Eve. It was so interesting and unforgettable. Justin was an excellent teacher, because he taught us not only how to study English well, but also the way to find out the beauty of the world and the way to be angels to others' lives. I know there was friendship and pure love in our hearts. Facing this valuable emotion neither nationality nor age was important, the real importance lay in faith, under-standing, and care. Justin is the best friend I have ever had, and I know I will cherish those days of staying together with him as the best part of my memory.
Friendship is a kind of treasure in our lives. It is actually like a bottle of wine, the longer it is kept, the sweeter it will be. It is also like a cup of tea. When we are thirsty, it will be our best choice, but when we have enough time to enjoy ourselves, it is also the most fragrant drink.
However, in this fast-developing modern society, the reality is not that. More and more people forget to enjoy the beauty of life and -the beauty of friendship. They work hard in order to gain a higher position, in the society and to earn more money for their work. Of course, we don't deny that it is important to find a bet-ter place in our lives, but we wish more and more people could pay a little more attention to themselves and their friends. All of us have to spare some time for personal lives. We have to find the chance to express our emotion and love. When staying with our friends, we can release ourselves completely. We can do whatever we want, we can laugh together, talk together, and even cry to-gether. I should say that being together with our best friends is the most wonderful moment of our lives.
As we know, we would feel lonely if we didn't even have a friend. But it doesn't mean we could depend on our friends all the time. There is a famous motto saying that “A friend is like a quilt with cotton wadding, but the real thing that keeps you warm is your own temperature.” It is really true. We have to work hard together with our friends, encourage each other and help each other. When we receive love and friendship, we should repay as much as we can.
Finally, let's pray together now that one day, all of us could find the person we want to find, and could enjoy a real beautiful friendship in our lives. Let's pray the flower of friendship be-tween our friends and us would always bloom brightly in our hearts.

亲爱的老师，同学们：
我很高兴可以在这个课堂上做一次演讲。这一次，我想谈谈英语。我的话题是我爱英语。
正如每个人所知，英语在今天十分重要。它已经被应用到世界的各个角落。它已经成为商业上最为通用的一门语言并广泛的用于国际贸易。如果我们能说好英语，我们就有更多的机会成功。因为越来越多的人注意到这一点，学英语的人数正在已很高的速度增长。
但是对我而言，我学英语不仅仅因为它的重要性以及它的实用性，更是因为我喜爱英语。当我学英语时，我可以体会到一种不同的思维方式，它可以给我更多接触世界的空间。当我读英语小说时，我能感受到不同于阅读翻译文的快乐。当我说英语时，我可以感到自信。当我写英语时，我能够感到不同于汉语的那种美……
我爱英语，它给了我一个色彩斑斓的梦。我希望有朝一日我可以畅游世界，用我流利的英语，我可以和世界各地的人交友。我能看到许多的名胜。我希望我能够到伦敦去，因为那里是英语的故乡。
我也希望用我流利的英语来将我们的名胜介绍给说英语的朋友，我希望他们可以像我们一样的爱我们的国家。
我知道，罗马不是一天筑成的。(成功需要日积月累。)我相信在持续不断的努力学习下，总有一天我可以拥有一口流利的英语。
如果你想被爱，你就应该学着去爱他人。所以我相信我对英语的爱定将换来它对我的爱。
我相信总有一天我会实现我的梦!
谢谢!
Many people, especially young college students, like pop songs. They hum small tunes all the way to their schools and seem to be never tired of this. Some of them are even mad about pop songs, rock'n'roll in particular. They shout and shout until their voices become hoarse.
Others will submerge themselves in the romance of the love songs, with tears streaming down their cheeks. Despite such popularity of the pop songs, however, some people dismiss such kind of songs as crude and worthless. They hold that these songs are easy to sing and they are usually characterized with simple tunes which lack variety and depth. Based upon this, they say that pop songs should not have gained such popularity. Whereas many others stick to pop songs. Their lives seem to ha dull without songs.
In my point of view, pop songs should not be banned. True, their tunes are simple and sometimes repetitious, but this is not to say that they are of no artistic value. Folk songs are also quite simple in tune but no one could dismiss them as trash songs. There is no denying that some pop songs are equally excellent. Why? Because they are widely sung and widely remembered. For example, "Yesterday" is of high artistic value. No one can deny its beautifulness in tune. Of com-se, there are bad songs that will not last long, but pop song fans will give these songs their due by choosing to sing them or not.
i wanna welcome everybody here in this cheer team. thank you for coming here this morning to stand on my side cheering me on. it’s my dream to have the opportunity to challenge all the foreign athletes to the championship at this great occasion: 20xx olympic games. now, the dream came true. as an athlete of china, i’m here to win the gold medal of orienteering for our motherland.
i’m so proud of being one of the best players in the world. but could you believe i had been a lazy girl when i was in junior high. i’m not kidding! at that time, running was my last favorite. i really don’t know how to describe the first time i was on the track. it was horrible. when i started to run, i was simply out of breath. and while i touched the finishing line, i really didn’t know if i was still alive. it’s so funny, huh? but it’s true, i did.
well, something happened and changed the situation. we won the right of holding the olympic games in 20xx. after that, sports became a kind of game in campus. and there are many sports clubs in school. one day someone asked me:“are you gonna try one of those?”first i felt so wired.
“try to get into sports clubs? are you kidding?” i said. and she goes: “why not it’s not hard at all, and so fascinating!” so i did tried one and i was so lucky to become one of those who did orienteering. that is a fantastic sport! you need to run and find where to go just by using a map and a compass. it’s wasn’t popular in china at first. but when we heard it might become a new event in 20xx, we did practiced hard, and aimed to win the first champion of orienteering in the world. when we practiced, there were a lot of troubles. you know, sometimes you need to go with your feet, but sometimes you need to go with your heart. in some situations, we faced the difficulties and problems. and we need to solve that through teamwork and strong willpower. so we can run faster, go higher and be stronger. that is what we say—olympic spirit.
now the dream came true. i’m standing here with all my body and my heart put in sports. so do the people from all over the world to here at the olympic games. it’s the olympic games that make us together. we are here for a big day of sport; we are here for a dream of sports. we are here for a spirit of sport that encourages us to face the difficulties of today and tomorrow.

they might become stronger and cleverer because of me.
that is a very contented feeling.
china is a developing country.
My dear friends,
DREAM——A word that has changed the world
Hello,everybody !it is my great honor to be here to share my idea with you .Today,I will talk something about DREAM——A word that has changed the world .
“What do you think is the word that has really changed our world ”
When I was asked about this question for the first time ,without thinking it too much ,a word flash into my mind ——DREAM ,D-R-E-A-M.People more or less dream about different things ,to be a teacher ,a doctor ,a scientist ,a businessman and so on .All these people who have dreams should be respected ,because Dreams make the world go around .We grow great by our dreams.All big men are great dreamers in their youth.Everyone has a dream ,and everything starts as one’s daydream.
Martin Luther king had a dream.He desired for a future where blacks and whites would coexist harmoniously as equals.By speaking the way he did,he educated,he inspired,he informed not just the people there,but people throughout America and unborn generations.He pushed forward the pace of American black society towards the racial equality .
Thomas Edison had a dream.He dreamed of a lamp that could be operated by electricity,began where he stood to put his dream into action,and despite more than ten thousand failures,he stood by that dream until he made it a physical reality!And today,his dream lights up the world at night.
Walt Disney had a dream.This,in itself,wasn't unusual -- he was always dreaming.He dreamed of making the first animated feature film,and of building an amusement park that parents could enjoy right along with their kids.Walt Disney empowered his dream and today,Disneyland,Disney world and Disney theme parks attract around the world thrill millions of visitors each and every year.
John F.kennedy had a dream.He wanted to land a man on the moon and return him safely to earth so as to restore faith in the American way of life.John F.kennedy empowered his dream and 8 years later Neil Armstrong stepped on the face of the moon.The moon landing certainly gave Americans new found confidence.
Dream --- A word that has changed the world Yes ,I would say so ,wouldn’t you
Youth is a special life relay station ,the growth with the worry ,the life feeling become aware happily with the dream ,collected a unique youth melody in here .
We decide.We choose.And as we decide and choose,so are our lives formed.In the end,forming our own destiny is what ambition is about.And most importantly ,You are the one you choose to be.
It is easy to waste our lives ,our days ,our minutes .It is easy to exist than living .So hold fast to your dreams,For if dreams die,life is a broken-winged bird,That cannot fly.Hold fast to your dreams,For when dreams go,life is a barren field,Frozen with snow.

Just make to it the finals, they had to get past 60 others speaking on “The impact of globalization on traditional Chinese values”。 That was at the semi-final on April 8-9. What will Chinese college students think about the impact? Each contestant had his own take on the subject. Xia summed up globalization by saying: “It’s just controversial and hard to say whether it is good or bad.” Xia took the old wall of his city, Nanjing, as a metaphor. He spoke about the conflict over whether to protect the old walls or tear them down to represent the conflict of ideas. He suggested that people protect the wall as a valuable relic while tearing down the “intangible walls” of their minds that prevent communication. While some other students are more focusing on the impact of globalization on family relations, attitudes towards love, and job-hunting.
Over the past 10 years, the national English speaking competition has given contestants a chance to speak on a variety of topics closely related to their lives. Chinese students become more open-minded and receive various ideas and thinking over the decade. Diversity becomes more obvious on campus, students have more opportunities to express and show themselves. It’s not an easy task for the contestants to win through the fierce competition. Owning to their passion, hard work and persistence, they finally succeeded in the contest.
Liu Xin, the first champion of the national contest, is now an anchorperson of CCTV-9. Recalling the passion of study on campus, she said: “When you want to express your idea by a foreign language without finding a right way, you’re really upset. Then you have to encourage yourself, and after a long term of bitterness, suddenly you find you get the right way with joy.” With the champion title in 21st Century Cup, Liu attended the International Public Speaking competition in London in May 1996 afterward and got the first prize historically.
The winner in 20xx surprised the audience, since she came from accounting major instead of English major. Gu Qiubei, then 22 years old, was a senior in Shanghai Foreign Studies University. While being asked whether she had some good methods to learn English, she said: “Learn English with passion and enthusiasm.” Attracted by the greatness of English language, Gu even changed her major from accounting to English in her postgraduate study. The most important issue in English learning process she pointed out is personal interests. Only people interested in English benefit a lot from the learning methods and those with passion will finally achieve their dreams.
When chief of global media giant Viacom Sumner Redstone gave a speech in Tsinghua University on his autobiography A Passion to Win, he was asked what made him to restart his career at the age of 60, the 81-year-old media tycoon said: “Firstly, there’s a self-driving force in my deep heart, which keeps my passion to succeed and surpass others; secondly, I don’t think I’m too old to leave work, actually I love my work very much.”
Some of the contestants have achieved their dreams as Redstone; still others are on the way to their dream. With a passion to win, you will overcome obstacles and succeed at the end.
I’m studying in a city that’s famous for its walls. People who visit my city are amazed at the imposing sight of its walls, especially when silhouetted against the setting sun with gold, shining streaks. The old, cracked bricks are covered with lichens and the walls are weather-beaten guards standing still for centuries.
Our ancestors liked to build walls. They built walls in Beijing, Xi’an, Nanjing and many other cities, and they built the Great Wall, which snakes across half our country. They built walls to protect against enemies and evil spirits. This tradition has survived to this day: we still have many parks and schools walled off from the public.
For a long time, walls were one of the most natural things in the world to me.
My perceptions, however, changed after I made a hiking trip to the eastern suburbs of my city. My classmates and I were walking with some foreign students. As we walked out of the city, we found ourselves flanked by tall trees, which formed a wide canopy above our heads. Suddenly one foreign student asked me, “Where is the entrance to the eastern suburbs?”
“We’re already in the eastern suburbs,” I replied. He seemed taken aback, “I thought you Chinese had walls for everything.” His remark set off a heated debate. At one point, he likened our walled cities to “jails”， while I insisted that the eastern suburbs were one of the many places in China that had no walls.
That debate had no winners, but I did learn a lot from this student. For instance, he told me that some major universities like Oxford and Cambridge were not surrounded by walls. I have to admit that we do have many walls in China, and as we develop our country, we must look carefully at them and decide whether they are physical or intangible. We will keep some walls but tear down those that impede our development.
Let me give another example.
A year ago, when I was working on a term paper, I needed a book on business law and found a copy in the law school library. However, the librarian coldly rejected my request to borrow it, saying, “You can’t borrow this book, you’re not a student here.” In the end, I had to spend 200 yuan to buy a copy. Meanwhile, the copy in the law school gathered dust on the shelf.
At the beginning of this semester, I heard that my university had started to think of unifying its libraries and linking them to libraries at other universities, so my experience wouldn’t be repeated. Barriers would be replaced by bridges. An inter-library loan system would give us access to books from any library. With globalization and China integrated into the world, I believe many of these intangible walls will be knocked down.
I know that globalization is a controversial issue, and it is hard to say whether it is good or bad. But one thing is for sure: it draws our attention to China’s tangible and intangible walls and forces us to examine their role in the modern world.
And how about the ancient walls of mine and other cities? Should we tear them down? Definitely not. My city, like Beijing and other cities, is actually making a great effort to preserve the walls. These walls attract historians, archaeologists, and many schoolchildren who are trying to study our history and cultural heritage. Walls have become bridges to our past and to the rest of the world. If the ancient builders of these walls were still alive today, they would be proud to see such great changes in the role of their walls. They are now bridges that link East and West, South and North, and all countries of the world. Our cultural heritage will survive globalization.

There is nothing bigger or older than the universe. The questions I would like to talk about are: one, where did we come from? How did the universe come into being? Are we alone in the universe? Is there alien life out there? What is the future of the human race?
没什么比宇宙更广大更久远的了。你们的问题中我想聊一下的是：你我何从?宇宙何来?宇宙中就只有我们?有外星异生物么?人类的未来将会如何?
Up until the 1920s, everyone thought the universe was essentially static and unchanging in time. Then it was discovered that the universe was expanding. Distant galaxies were moving away from us. This meant they must have been closer together in the past. If we extrapolate back, we find we must have all been on top of each other about 15 billion years ago. This was the Big Bang, the beginning of the universe.
上世纪20xx年代之前，所有人都以为宇宙基本上是处于稳态，流金岁月，持恒不变。之后我们发现原来宇宙正在膨胀中。辽远星系一直飞离我们，这意味着它们必定曾相靠近。我们若往后推算，就会发现我们必都曾於约150亿年前，互相堆叠在一起。正是这 "霹雳大爆炸" ——宇宙之起始。
But was there anything before the Big Bang? If not, what created the universe? Why did the universe emerge from the Big Bang the way it did? We used to think that the theory of the universe could be divided into two parts. First, there were the laws like Maxwell's equations and general relativity that determined the evolution of the universe, given its state over all of space at one time. And second, there was no question of the initial state of the universe.
然而大爆炸前可有什么吗?若是没有，又是什么创造宇宙呢?宇宙缘何要从大霹雳中冒出呢?过往我们都认为宇宙论可分成两部分，首先，是定律。像“麦克斯韦方程组”'和 “广义相对论”以其于同一刻设定整个时空之状态，而决定了宇宙之演化进程。次之，是对宇宙雏形的疑问。
We have made good progress on the first part, and now have the knowledge of the laws of evolution in all but the most extreme conditions. But until recently, we have had little idea about the initial conditions for the universe. However, this division into laws of evolution and initial conditions depends on time and space being separate and distinct.
第一部分我们取得良好进展，除了“至极端境况”'以外。现在已对演化规律于所有境况下之进程有所掌握。可直至最近，我们仍对宇宙初生当时之周围条件不甚了了。然而，这演化律及初始条件之界分，乃囿于"时 空分明"之概念内。
Under extreme conditions, general relativity and quantum theoryallow time to behave like another dimension of space. This removes the distinction between time and space, and means the laws of evolution can also determine the initial state. The universe can spontaneously create itself out of nothing.
而於极端条件下，广义相对论及量子论容许“时间”如同“空间”的另一维度般运作。这就将“时.空”之间区别移除了，即是说演化律 亦可决定初始状态。宇宙可以由无变有自我创生!
Moreover, we can calculate a probability that the universe was created in different states. These predictions are in excellent agreement with observations by the WMAP satellite of the cosmic microwave background, which is an imprint of the very early universe. We think we have solved the mystery of creation. Maybe we should patent the universe and charge everyone royalties for their existence.
我们甚至可以计算出宇宙在不同情况下诞生的可能性。这些推论与WMAP卫星所观测到的宇宙微波背景辐射(即大爆炸之痕迹)相当一致。我们相信已勘破了创造奥秘或许我们应将“宇宙”给注册，然后向每个生存于世的人收“生活费”。
I now turn to the second big question: are we alone, or is there other life in the universe? We believe that life arose spontaneously on the Earth, so it must be possible for life to appear on other suitable planets, of which there seem to be a large number in the galaxy.
现在我转到第二个大问题去，宇宙中就只有我们，还是另有其它生物?我们相信生命从地球自我衍生，故此生命确有可能出现於其它合适星球——星河中看来可有不少呢。
But we don't know how life first appeared. We have two pieces of observational evidence on the probability of life appearing. The first is that we have fossils of algae from 3.5 billion years ago. The Earth was formed 4.6 billion years ago and was probably too hot for about the first half billion years. So life appeared on Earth within half a billion years of it being possible, which is short compared to the 10-billion-year lifetime of a planet of Earth type. This suggests that the probability of life appearing is reasonably high. If it was very low, one would have expected it to take most of the ten billion years available.
但我们仍未搅通生命是如何生成：对於生命诞生的可能契机，我们有两项观测得来的佐证。首先我们有来自35亿年前的海藻化石。地球于46亿年前形成，头约5亿年相信仍太热了。故此生命于其变得可能后的5亿年间方出现，这相对于像地球之类百亿年期的星体，只算是一段短时间。这意味着生命出现的概率是颇高的。若是低的话，就可预期要花尽百亿年的绝大部分才会出现。
On the other hand, we don't seem to have been visited by aliens. I am discounting the reports of UFOs.Why would they appear only to cranks and weirdos? If there is a government conspiracy to suppress the reports and keep for itself the scientific knowledge the aliens bring, it seems to have been a singularly ineffective policy so far. Furthermore, despite an extensive search by the SETI project, we haven't heard any alien television quiz shows. This probably indicates that there are no alien civilizations at our stage of development within a radius of a few hundred light years. Issuing an insurance policy against abduction by aliens seems a pretty safe bet.
另一方面，我们似乎从未见有外星人到访。我不信那些什么“不明物体的报导”。它们干吗要单向那些古古怪怪的人现身呢?若真有一个甚麽政府阴谋要将报导打住，从而将外星人所带来之科学识据为己有，那可真像个既离奇，亦从未见效的举措。再说，即便SETI计划已进行广泛探索，我们还没有收听到任何外太空电视答问节目。这可能昭示在我们现阶段文明发展之方圆数百光年范围之内，并没有其它外星异文化。卖保险给那些怕被外星人绑架的人，看来是个不错的选择。
This brings me to the last of the big questions: the future of the human race. If we are the only intelligent beings in the galaxy, we should make sure we survive and continue. But we are entering an increasingly dangerous period of our history. Our population and our use of the finite resources of planet Earth are growing exponentially, along with our technical ability to change the environment for good or ill. But our genetic code still carries the selfish and aggressive instincts that were of survival advantage in the past. It will be difficult enough to avoid disaster in the next hundred years, let alone the next thousand or million.
这送我到了最后一个大问题：人类的前途。若我们是星河里唯一智能生物，就必须确保自己能存活并延续下去。但我们正迈入历史中一个愈发危险的时段。我们的人囗和对地球有限资源的耗用，正以几何级数增长，相随的是我们将环境或弄好或弄垮的技术才能，至于我们的基因指令则仍带着那自私和好斗的本质，这或有利于我们过往求存，却又让我们于往后数百年内人祸难逃。更别说未来千百万年了。
Our only chance of long-term survival is not to remain inward-looking on planet Earth, but to spread out into space. The answers to these big questions show that we have made remarkable progress in the last hundred years. But if we want to continue beyond the next hundred years, our future is in space.That is why I am in favor of manned — or should I say, personned — space flight.
我们长活下去的唯一机会，不是一直呆着在地球而是冲出太空去。这些大问题之解答显示我们于过去数百年取得可观进展。可若要超越未来数百年，们的前途在于太空。正因此，我较倾向于 "人" 控——( man 于英语中可单指'人或“男人”) 或许我应说，由人驾驶之太空旅航。
All of my life I have sought to understand the universe and find answers to these questions. I have been very lucky that my disability has not been a serious handicap. Indeed, it has probably given me more time than most people to pursue the quest for knowledge. The ultimate goal is a complete theory of the universe, and we are making good progress. Thank you for listening.
我一生都在探究想要了解宇宙并找出这些问题之答案。我一直都非常幸运，我的残疾并没造成严重障礙;说真的，这反倒让我比大部分人获得更多时间以从事知识之追求。终极目标是一套完备的宇宙论，而我们已有良好进展。感谢您们的聆听。
Chris Anderson: Professor, if you had to guess either way, do you now believe that it is more likely than not that we are alone in the Milky Way, as a civilization of our level of intelligence or higher? This answer took seven minutes, and really gave me an insight into the incredible act of generosity this whole talk was for TED.
安德森：教授，若您必须二选其一作猜测，此刻您是较相信还是较不相信我们是天河中唯一现水平或更高水平之智能文化?准备这答案已花了7分多钟，真让我深切体会到这整个演讲为TED所付出之，让人难以置信之慷慨。
Stephen Hawking: I think it quite likely that we are the only civilization within several hundred light years; otherwise we would have heard radio waves. The alternative is that civilizations don't last very long, but destroy themselves.
霍金：我想我们应该是数百光年范围内之独一文明;否则我们应已收听到电波。另一种可能是，该等文明都维持不久，就自我毁灭掉。
CA: Professor Hawking, thank you for that answer. We will take it as a salutary warning, I think, for the rest of our conference this week. Professor, we really thank you for the extraordinary effort you madeto share your questions with us today. Thank you very much indeed.
安德森： 霍金教授，谢谢您的解答。我想，我们会将之作为这一周余下会谈之座右铭。教授，我们衷心感谢您今天为与我们分享您的问题所作出之卓越贡献。真的非常感谢您。

In china，people believe that，at the beginning，the tiger and the cat were friends，and the cat was much smarter than the tiger cat learned the physical skills quickly，and the tiger was always ually，the tiger had to learn from the cat，and the cat was patient to teach the after day，month after month，finally，the tiger could also run，jump，roll，grasp，tear，and strike as well as the cat.
One summer afternoon，the cat was taking a nap as the tiger sitting ing at the cat，the tiger suddenly thought，why should he keep befriending with such a small animal since he had already learnt all the skills from the cat?The evil tiger decided to kill the sleeping cat as a before dinner tiger stood up and approached the cat as this moment，the cat woke ing up her eyes，the smart cat immediately realized what the tiger was trying to do and swiftly jumped onto a nearby tall tree and climbed to the top branch.
The tiger thought he had already learned every skill from the cat he never knew that the cat had hidden the tree climbing from him.
“I kept the last technique of the tree climbing from you just because I suspected you might be can ungrateful friend.” The cat loudly told the tiger who watched under the tree helplessly.
The future is in my eyes how good a word! Some people think the future is a long way off, and I think it is often fantasies of the future, be a good thing.
I close my eyes and dream, maybe I will become a people's teacher in the future. One day, I finally became a respected teacher, has not said a word: "the teacher is human soul engineer?" I came to the new school, began to some nervous, but when I see one lovely smiling face, I all taut nerves relaxed. Began to chat with students, thus learned that the aspirations of their pupils... In class, I will be very serious, the class, I like their big sister, play games with them, chatting, so that we can promote the relationship between the teachers and students. As long as students have no problem, I will help them patiently. Good a dedicated teacher.
Often fantasies of the future, like to learn their ideal. Fantasy back to the pursuit of the future is very important in the future. Only you can change the future, I have never said that the future will change because of you. But the opportunity is created by yourself, and to cherish every opportunity to achieve their own future
Our country many cities have produced fog, the visibility is very low, so this time the traffic accident rate increases, we haven"t got the security guarantee.
Today, my home is also suffered heavy fog, the window of white, what also can"t see. My home is fog, the air quality is greatly decreased, in order to prevent the body health must wear a face mask to go out.
Today I walk on my way to school, the hateful haze let I almost hit against the tree. Pedestrians in a hurry to walk, large and small are wearing masks. Car kept honking, like to the accompaniment of dust, mist in the headlights, fog haze of dust in the dancing joyfully, from automobile exhaust vent curling into the sky, more than a piece of tail gas, is more than a haze, our safety is more dangerous.
Sky is not blue, trees are not green, white cloud is away, the culprit is the human oneself! Human ah! Return the previous green homes to us!
"Children over 15 should be allowed to make decisions about their lives without the interference of their parents or teachers. Society should accept that children mature at a younger age and should adjust the law accordingly."
The fact that we are not able to determine the exact moment at which maturity is realized due to the gradual changing nature of the growing process does not prevent us from establishing a practicable criterion by using the concept of a legal age, and placing on it an excessive amount of reliance as if it were a creed.Objectively, since the interpretation of maturity merely bears a local, temporary meaning (e. g. , it is understood distinctly in different cultures), not to mention the diversity of particular individuals, clearly an age criterion is definable only in the sense of statistics, yielding an average result of which the legislation should be adjusted to. However, no evidence indicates the invariance of the statistical result under the vicissitudes of the times.
Persisting in an a priori assumption may not be as highly laudable and dependable as believing in an empirical conclusion.While, both facts and analyses, verifying uniformly the time-dependency of the statistical mature age, suggests the shift to a younger age of children‘s maturity.
In reality, phenomena serving as foundations of the above statement are enormous, such as the manifest superiority of the young in knowledge structure and quantity to their elder generation for a corresponding age, their highly developed intelligence and advanced ability in comprehension and their sophisticated behavior in schools and their communities. Neither could all related evidence be listed, nor should it be ignored. Even with a phcnomenological attitude, one is bound to perceive the indispensability of a change to the old rule to meet the requirement of the new situation.
Analyses yield an identical verdict. A brief investigation of new situation.
Analyses yield an identical verdict. A brief investigation of the environment in which the new generation has been brought up is sufficient to justify all the observed phenomena. Physiologically, unimaginable revolutions in food supply and nutritional structure took place globally after the 2nd World War, which,together with other developments concerning living conditions,guarantee the necessary material bases. Psychologically, the young, confronted with a world of information and education,are entitled to nearly the same rights and freedom as the adults in front of the television or other mass media. They know everything. They understand everything.
The determination of the mature age is based on scientific principles rather than on doctrines. If the young, indeed, possess judgments by no means inferior to that of the generally acknowledged adults, others should treat them as adults, allowing them to make decisions independently. Moreover, there is no difficulty in the law, which is not the truth of the universe, but a sheer compromise of social forces, and have undergone innumerable historical modifications and revolutions with a potential
transformation today.
Though the precise new legal mature age is only attainable through statistics, the obvious tendency implies an absolute modification. With an unknown date of realization, it is expected that teachers and parents should discard the traditional ideas and really treat the young equally when the time comes.
What is success? It is what everyone is longing for.Sometimes success would be rather simple. Winning a game is success; getting a high grade in the exam is success; making a new friend is success; even now I amstanding here giving my speech is somehow also success.
However, as a person’s whole life is concerned, success becomes verycomplicated. Is fortune success? Is fame success? Is high social status success? No, I don’t think so. I believe success is the realization of people’ s hopes and ideals.Nowadays, in the modern society there are many people
who are regarded as the successful. And the most obvious characteristics of hem are money, high position and luxurious life. So most people believe that s success and all that they do is for this purpose. But the problem is wether it is real success. We all know there are always more money, higher position and better condition in front of us. If we keep chasing them, where is the end? What will satisfy us at last? Therefore, we can see, to get the real Success we must need something inside, which is the realization of people’ hopes and ideals.
What is success? Everyone has his own interpretation as I do. But I am sure every success leads to an ever-brighter future. So ladies and gentlemen, believe in our hopes, believe in ourselves, we, every one of us, can make a successful life!
Wish you all good success!
Schoolmates:
When you look the lovable animated cartoon, plays is in a stew human's computer games, rides the fast train, is answering transoceanic telephone time, ......Not only your might once realize the science the strength, the science changed this world, also changed our life, the science side us.
Opens for the 20th century the grand chapters, not only we discovered the humanity to experience the blood and the fire baptism in these hundred years, has created the innumerable scientific miracles. 19th century France famous science fiction writer of fiction verne fictionalizing, at that time let the human be inconceivable, he fantasized moon landing travel, the airplane, the long-range gun and so on, all 11 became the reality in the 20th century. In the 21st century today, the high tech is ubiquitous.
As cross-century one generation, how posture should we adapt the new century by, the load get up the new century heavy burden? Not only science and technology changing with each new day, causes the science to serve for the most advanced technique, also more and more many seeps to during ours daily life, this needs us who is in the young people time to deeply love the science, the study science. Participation science and technology “five small” competition, reading science and technology books, caused me to understand many truths. The precise robot, does not use the fuel the automobile, the hypothesized soccer game, high tech information transmission and so on, each one vivid interesting phenomena, aroused me to explore the science the desire.
Our each people all want to study the science, the dissemination civilization, while enjoys the new life, must create the new life, now, the technical product renewal speeds up unceasingly, the visible television, the computer surfer, the pacemaker, already did not calculate was fresh. Vacuum cleaner invented which from 1901, to the artificial earth satellite, carried the human spaceship, the science and technology demonstrates the formidable strength in the different domain. Electronic industry, communication technology daily popularization, nanotechnology, superconductivity material widespread application, soon one day, perhaps in yours dinner table, can appear likely bio-engineering foods and so on outer space green pepper, man-made beefsteak. Studies the science and technology, is not merely in order to become the scientist, also is for can adapt the life, more has been able to become the new century the master, the load gets up the new century, is the national construction, makes the contribution for the human culture.
Since new China had been established, our country's technical development progresses by leaps and bounds, the synthesized insulin, finishes a job plants, the hybrid rice again, explodes atomic bomb and hydrogen bomb, launch satellite and airship and so on, these technical achievement which focuses attention on the common people, reduced our country and the advanced countries science and technology disparity greatly, has poured into the vigor for our country's modernization. Grandpa Deng Xiaoping said “the science and technology is the first productive forces”, indeed so, the science has inserted the wing for our motherland soaring. Chairman Mao Zedong once said to the youth that, the world was you, also is we, but is your in the final analysis. This speech, has been full of the elders to our earnest expectation. If the elders have constructed the 20th century motherlands with the industrious work, that, we should by the knowledge, get up the new century heavy burden by the scientific load.
Schoolmates, we are being at the growth developmental stage, the study science, lets us start since childhood. We must learn each kind of literacy class diligently, because this is all study foundation; At the same time, to each kind the popular science books, the publication which suits our elementary student to look, should better read some in the after school; Also should begin to do each science small experiment, the small manufacture positively, writes the science small paper and so on, raises to the science interest. Long this gets down, we can certainly deeply love the science, has the rich scientific knowledge. Humanity's wisdom is infinite, regardless of is US's Challenger number detonation, the whole world computer virus' promotion, always all cannot prevent humanity's advance in technology. “The knowledge is the strength”, Bacon this sentence enjoys great popularity the maxim did not know had driven how many earnestly seeks the knowledge human. Now, lets us also use it to encourage oneself, makes one to deeply love the science the new generation, the load gets up the new century heavy responsibility, for our motherland tomorrow, will compose a more magnificent poem!
Thanks everybody.
英语励志演讲稿篇2中文翻译：
同学们：
当你们看着可爱的动画片，玩着迷人的电脑游戏，坐上快速的列车，接听着越洋电话的时候，……你可曾意识到科学的力量，科学不仅改变了这个世界，也改变了我们的生活，科学就在我们身边。
翻开20世纪的壮丽篇章，我们发现人类在这百年中不仅经历了血与火的洗礼，更创造了无数科学奇迹。19世纪法国著名科幻小说家凡尔纳的虚构，当时让人不可思议，他所幻想的登月旅行、飞机、远射程炮等，在20世纪都一一成为现实。在21世纪的今天，高科技更是无处不在。
作为跨世纪的一代，我们又该以怎样的姿态去适应新世纪，担起新世纪的重担呢? 科学技术的日新月异，使得科学不只为尖端技术服务，也越来越多地渗透到我们的日常生活之中，这就需要正处于青少年时代的我们热爱科学，学习科学。参加科技“五小”比赛、阅读科技书籍，使我明白了许多道理。精密的机器人，不用燃料的汽车，虚拟的足球赛，高科技信息的传送等等，一个个生动有趣的现象，激起了我探索科学的愿望。
我们每个人都要学习科学，传播文明，在享受新生活的同时，更要创造新生活，如今，科技产品的更新换代不断加快，可视电视、电脑上网、心脏起搏器，已经不算新鲜了。从发明的真空吸尘器，到人造地球卫星、载人宇宙飞船，科技在不同领域里显示出了强大的力量。电子产业、通讯技术的日益普及，纳米技术、超导材料的广泛应用，不久的一天，也许就在你的餐桌上，会出现像太空青椒、人造牛排等生物工程食品。学习科学技术，不仅仅是为了成为科学家，也是为了能适应生活，更为了能成为新世纪的主人，担起新世纪，为国家建设，为人类文明做出贡献。
新中国成立以来，我国的科技发展突飞猛进，人工合成胰岛素、断手再植、杂交水稻、爆炸原子弹和氢弹、发射人造卫星和飞船等等，这些令世人瞩目的科技成就，大大缩短了我国和先进国家的科学技术的差距，为我国的现代化建设注入了活力。邓小平爷爷说“科学技术是第一生产力”，的确如此，科学为我们祖国的腾飞插上了翅膀。毛泽东主席曾对青年说，世界是你们的，也是我们的，但归根结底是你们的。这句话，饱含了长辈们对我们的殷切期望。如果说长辈们用辛勤的劳动建设了20世纪的祖国，那么，我们就应该以知识、以科学担起新世纪的重担。
同学们，我们正处于成长发育阶段，学习科学，让我们从小做起。我们要努力学好各种文化课，因为这是一切学习的基础;同时，对各种适合我们小学生看的科普书籍、报刊，最好在课余多阅读一些;还应该积极动手搞各种科学小实验、小制作，写科学小论文等，培养对科学的兴趣。长此下去，我们一定能够热爱科学，拥有丰富的科学知识。 人类的智慧是无限的，无论是美国的挑战者号爆炸，还是全球计算机病毒的升级，从来都不能阻止人类的科技进步。“知识就是力量”，培根这句脍炙人口的格言不知激励了多少渴求知识的人。如今，让我们也用它来勉励自己，做一个热爱科学的新一代，担起新世纪的重任，为我们祖国的明天，谱写出更加辉煌的诗篇!
谢谢大家。
as we know, you have to learn how to fly much more independently instead of under your parents’ considerate protection when you get into college, which also means you will come across enormous questions that should be solved by yourself. from my point of view, those main problems can fall into three parts.
first of all, the complicated relationship. for one thing, you have to know how cultural differences function in your relationship and respect them. in addition, college students spend less time studying together owing to different courses’ choosing, which requires us to devote more energy to building relationship. for the other thing, it is also vital to communicate with your parents often by using mobile phones or other tools.
In the matter of courage we all have our limits. There never was a hero who did not have his bounds. I suppose it may be said of Nelson and all the others whose courage has been advertised that there came times in their lives when their bravery knew it had come to its limit.
I have found mine a good many times. Sometimes this was expected--often it was unexpected. I know a man who is not afraid to sleep with a rattle-snake, but you could not get him to sleep with a safety-razor.
I never had the courage to talk across a long, narrow room. I should be at the end of the room facing all the audience. If I attempt to talk across a room I find myself turning this way and that, and thus at alternate periods I have part of the audience behind me. You ought never to have any part of the audience behind you; you never can tell what they are going to do.
I'll sit down.
