President pitzer Mr. Vice President, Governor, Congressman Thomas, Senator Wiley, and Congressman Miller, Mr. Webb, Mr. Bell, scientists, distinguished guests, and ladies and gentlemen:
I appreciate your president having made me an honorary visiting professor, and I will assure you that my first lecture will be very brief.
I am delighted to be here and I'm particularly delighted to be here on this occasion.
We meet at a college noted for knowledge, in a city noted for progress, in a state noted for strength, and we stand in need of all three, for we meet in an hour of change and challenge, in a decade of hope and fear, in an age of both knowledge and ignorance. The greater our knowledge increases, the greater our ignorance unfolds.
Despite the striking fact that most of the scientists that the world has ever known are alive and working today, despite the fact that this Nation's own scientific manpower is doubling every 12 years in a rate of growth more than three times that of our population as a whole, despite that, the vast stretches of the unknown and the unanswered and the unfinished still far outstrip our collective comprehension.
No man can fully grasp how far and how fast we have come, but condense, if you will, the 50,000 years of man's recorded history in a time span of but a half-century. Stated in these terms, we know very little about the first 40 years, except at the end of them advanced man had learned to use the skins of animals to cover them. Then about 10 years ago, under this standard, man emerged from his caves to construct other kinds of shelter. Only five years ago man learned to write and use a cart with wheels. Christianity began less than two years ago. The printing press came this year, and then less than two months ago, during this whole 50-year span of human history, the steam engine provided a new source of power. Newton explored the meaning of gravity. Last month electric lights and telephones and automobiles and airplanes became available. Only last week did we develop penicillin and television and nuclear power, and now if America's new spacecraft succeeds in reaching Venus, we will have literally reached the stars before midnight tonight.
This is a breathtaking pace, and such a pace cannot help but create new ills as it dispels old, new ignorance, new problems, new dangers. Surely the opening vistas of space promise high costs and hardships, as well as high reward.
So it is not surprising that some would have us stay where we are a little longer to rest, to wait. But this city of Houston, this state of Texas, this country of the United States was not built by those who waited and rested and wished to look behind them. This country was conquered by those who moved forward--and so will space.
William Bradford, speaking in 1630 of the founding of the Plymouth Bay Colony, said that all great and honorable actions are accompanied with great difficulties, and both must be enterprised and overcome with answerable courage.
If this capsule history of our progress teaches us anything, it is that man, in his quest for knowledge and progress, is determined and cannot be deterred. The exploration of space will go ahead, whether we join in it or not, and it is one of the great adventures of all time, and no nation which expects to be the leader of other nations can expect to stay behind in this race for space.
Those who came before us made certain that this country rode the first waves of the industrial revolution, the first waves of modern invention, and the first wave of nuclear power, and this generation does not intend to founder in the backwash of the coming age of space. We mean to be a part of it--we mean to lead it. For the eyes of the world now look into space, to the moon and to the planets beyond, and we have vowed that we shall not see it governed by a hostile flag of conquest, but by a banner of freedom and peace. We have vowed that we shall not see space filled with weapons of mass destruction, but with instruments of knowledge and understanding.
Duanwu Festival (端午节, Duānwū Jié) is a traditional Chinese festival held onthe fifth day of the fifth month of the Chinese calendar. It is also known asthe Double Fifth.[citation(引用;引证) needed] It has since been celebrated, invarious ways, in other parts of East Asia as well. In the West, it's commonlyknown as Dragon Boat Festival.
The exact origins of Duan Wu are unclear, but one traditional view holdsthat the festival memorializes the Chinese poet Qu Yuan (c. 340 BC-278 BC) ofthe Warring States Period. He committed suicide by drowning himself in a riverbecause he was disgusted by the corruption of the Chu government. The localpeople, knowing him to be a good man, decided to throw food into the river tofeed the fish so they would not eat Qu's body. They also sat on long, narrowpaddle boats called dragon boats, and tried to scare the fish away by thethundering sound of drums aboard the boat and the fierce looking carved dragonhead on the boat's prow(船头).
In the early years of the Chinese Republic, Duan Wu was also celebrated as"Poets' Day," due to Qu Yuan's status as China's first poet of personalrenown(名声名望).
Today, people eat bamboo-wrapped steamed glutinous(粘的) rice dumplingscalled zongzi (the food originally intended to feed the fish) and race dragonboats in memory of Qu's dramatic death.

Good afternoon, everyone!
The topic of my speech today is “Do trust us—a generation born in the 90s”.
Living in an environment full of fierce competition, we, a generation born in
the 90s, are faced with more problems in entering higher schools and getting employed. Under these circumstances, we are developing our special manners and values, which has raised people’s concern.
They worry we care too much about ourselves and are unwilling to cooperate with others, which makes it hard for us to achieve success in whatever we do. Besides, they consider us as lacking in perseverance, and this is what it takes to do any job well. Without it, we may easily give up in time of difficulty. They are also concerned that we are so eager to win instant fame that we follow fashion blindly, which will in turn ruin our values and future.
However, we, a generation born in the 90s, have our own advantages despite some weaknesses. Firstly, we have the courage to meet challenges and take risks, which helps realize our dreams. In addition, we are quick-minded and creative. We can do our work more efficiently. Of course, we still need to learn more from those experienced. Please do trust us!
Thank you for your listening!

Students, guests , teachers and Honorable Judges
Good morning !
my great pleasure to share my dream with you today. my dream is to become a teacher....
As the whole world has its boundaries, limits and freedom coexist in our life. I don’t expect complete freedom, which is impossible. I simply have a dream that supports my life.
I dream that one day, I could escape from the deep sea of thick schoolbooks and lead my own life. With my favorite fictions, I lie freely on the green grass, smelling the spring, listening to the wind singing, breathing the fresh and cool air and dissolve my soul in nature at last. Simple and short enjoyment can bring me great satisfaction.
I dream that one day the adults could throw their prejudice of comic and cartoon away. They could keep a lovely heart that can share sorrow and happiness with us while watching cartoon or doing personal things. That’s the real communication of heart to heart.
I have the belief that my dreams should come true. I am looking forward to some day coming when I am like a proud eagle, which flies to the blue and vast sky.
Thank you!
I came to Los rela_ation although only one month, but in this short month,the company made me feel that the work of leadership e_cellence, continuousinnovation, for employees in every possible way for me to join ------ Losrela_ation is lucky. To become a member of the company, I feel very proud, Ibelieve that pride will make me even more passion into work.
As a new work environment into a new staff, although in the past haveaccumulated some e_perience, but just went to the company, is inevitable, or alittle pressure. In order to make their working status as early as possible andadapt the working environment, there are problems in time to ask my colleaguesto actively work to learn the necessary e_pertise to improve their professionallevel. During this time I learned a lot of knowledge, their skills have beengreatly improved, passes very full and happy, No matter how tired it is worthit!
Here, I especially want to thank me during this time to help the leadershipand colleagues, it is because of the meticulous care and trouble they help meget it as soon as possible from the kind of tension in the liberation, so Iquickly adapt to the environment, love to put all the work! As I understand it,Los rela_ation is concerned about their every employee to have enough space foreach employee showing themselves! In Los rela_ation, I like the clerk of thiswork, because this post is highly challenging, let me put 10 years of knowledgeand apply their knowledge, and can play well I plan to deal with issues such ascapacity it is because of work like, so that I can whole-heartedly to work.
I know that the only positive action can bring about fruitful results. Inorder to do a good job selling this work, I was led to my heart's doing eachtask. For me, Los rela_ation is a new environment different from the past, havecontacted all the people and things are new.
As a new employee, I'm going to take the initiative to learn, adapt to theenvironment, while also showing his respect superior to the company, in fulltrust and cooperation will be based on good relationships. In addition, I wouldlike to learn at all times maintain a high passion, constantly added knowledgeand skills to adapt to development of the company. I am at work there may beconfusion and pressure, but I believe that as long as the correct attitude tohave full confidence in the courage to go on, it will be a success.
Community development, information is growing, the challenges areincreasing. I not only want to play to their strengths, but also to learn fromthe e_perience of others through, to improve their own quality. Los rela_ thecompany's development goals are ambitious and long-term, the company'sdevelopment is that every one of us, I believe I have the ability to grasp theopportunity to challenge together with the Los rela_ation!
As is known to all, opportunities always coexist with challenges. They altogether play great roles in achieving success in any field, whether to an individual, a community or even to a country.
what is the relationship between opportunities and challenges? For one thing, in order to seize opportunities, we must be ready to meet challeges, just as the proverb " God helps those who help themselves" shows. Meeting challenges means paving the way for opportunities. For another, opportunities are accompanied by challenges. A good case in point is China's entry into WTO, which provides us with more opportunities in economic growth, while, at the same time, brings us fierce competitions from foreign countries. Thus only by dealing with both of them properly can we reach our goal smoothly.
From my perspective, the more challenges we have, the more chances we'll get to improve our world. We should enjoy being challenged because it's a world full of competitions. In a word, success will be round the corner if we hold the opportunity tightly and face the challenges bravely, confidently and optimistically.
In this fast-paced modern society, life can be sometimes very stressful. One may get overwhelmed by what's going on. There may be a feeling of helplessness and the world's spinning out of control. It's easy to lose hope. However, hope is something can be created with an optimistic state of mind.
Optimism helps to increase hope for several reasons. To begin with, hope is something appears from our inside world. All of us have capacity to generate hope. This capacity is closely related to optimism. Optimism help us overcome fear, supporting us with great courage and confidence to overcome any difficulties. In return, it allows us to hold on to hope. Whatever we do or whatever is done to us, it is always constructive to adopt an optimistic attitude. As the saying goes, smile and the world smiles with you, weep and you weep alone. If you let yourself down, no one can pull you out and the situation could only go from bad to worse. But as long as you have an optimistic state of mind, you can have the situation under your control and therefore be more hopeful. Last but not least, God help those who help themselves. We should first be optimistic and hopeful can we help ourselves. And then you can get help from others. Once you get through the bad situation, hope will eventually be increased.
There are many students smoking in senior high school, the reason may be that they think they look cool or appear to be more mature while having a cigarette at hand.But there are a lot of reasons not to smoke. Smoking does harm to our health.It is dangerous to our heart and lung. A lot of diseases are caused by cigarettes.Cigarettes also have terrible smell.The seconghand smoke can also be dangerous to the others who stand around you. Therefore, no smoking in public is a strict regulation in many countries. And the most important thing is that once you come into addicitive,it's hard to get rid of it. So,we must keep far from the cigarette——for everybody's health.

students in this 9.6 million square kilometers of land, which his uncle did not know the name! his name is called - lei feng.
when they replace their vehicles in a business trip, feng found a middle-aged woman carrying a child’s train ticket, and lost money, he used his allowance to the sister-in-law bought a train ticket from jilin go. it is therefore a stay chuan phrase: "lei feng travel thousands of miles one good one to do the train." this is lei feng.
lei feng selfless, willing to sacrifice things really are too much.
today, the lei feng spirit of the people in the probation, in between there are a lot of our revolution, "fool." lei feng has left us more than 4years, but his spirit is with the times, shine forever.
traffic police, they stand in the street on day and night, to withstand the test of wind and rain, frost withstand the torture, whether it is a cold winter or hot summer, they always standing there; regardless of family and friends are still ordinary people, they always impartial and incorruptible, impartial treatment. they pay for this cause too much too much, sacrifice too much, no matter how difficult the road, they decided to do so. traffic police are not our great-human transmission is lei feng?
the teacher, they work day and night, i do not know the number of correct operation, i do not know how many little rest at night. in their teachings, we know how to make an aspiring person, a noble person, a moral person, a person the benefit of the people; in their care under the guidance, i do not know how many people have embarked on a the success of the road. they love their work, paid in full, return was always someone else’s happiness. them asa candle, burning himself, and lit up the others, and our hard won ding lei feng-human transmission is not it?
The world is not only hungry but also thirsty. However, some people are still reluctant to turn a finger to save water. Some people don't turn a tap after use, while others even pollute clean water. The severe drought in the southwest China once again pushes the issue of water-saving under hot discussion.
However, as things stand today, the reasonable utilization of water resource is more significant than before. Firstly, the quick development of commerce and industry will consume more water for their reproduction. What's more, the great increase of the world population also further aggravates the situation. Secondly, due to the more and more serious water pollution, the supply of clean water fails to meet the demand.
As a college student, not only will I save water by myself, but also I will attend different kinds of activities on water-saving. On the one hand, I will make the best of water instead of throwing clean water away. On the other hand, I will call on my friends to save water and protect water. (180 words)

Smile to Life
Hello, everybody. My name is Huang Wenjie. I am from Haikou No. 9 Middle School. My topic today is Smile to Life.
Do you always smile to life? If the answer is yes, I think you’re a very happy person.
If a person feels happy, his smile just shows he is glad. It’s very normal. But if you feel sad, what should you do? As a junior student, we should learn to smile to life. There are many bad things in our study life,such as some bad exams or a difficult game. When difficulties come, what will you face to them? I think smile is the best way for us.
When you do badly in an exam, smile to life. Tell yourself to be happy. Now since things have happened, your anger and sadness will do nothing. Instead it’ll even do harm to your health. Why not smile and do better next time?
When you have a difficult game, smile to life. It can make you braver. Do believe yourself. And smile will give you power to win the game!
Don’t be sad for pity things. It is said, if you smile to life, life will smile to you. So please smile to life, friends!
My speech is over. Thank you for listening.
A speciality can be almost anything a person likes to do in his spare time.specialityists raise petsbuild model shipsweave basketsor carve soap figures and so on.In a wordspecialities offer enjoymentfriendshipknowledge and relaxation.
Thenwhat is my speciality?Wellwhat I like most is singing.I began to sing songs when I was very young.My uncle was studying in a college thenso he could sing lots of songsand he taught me several songs.I showed great interests in the music thenfor they were pleasing to ears and easy to sing.My uncle told me they were called pop songs.
When I grew upmy music teacher found that I had a good voiceso she sent me to the Children's Palace to study vocal music.From then onI began my vocal music training.And then I knew there were several kinds of songslike folk songspop songs and so on.What I had learned most was the songs for children.They were all simple ones but our teacher trained us very strictly.We practiced how to produce sound and how to make our expression more natural and more pleasing.Those simple training didn't reduce my interest in singing at all and I won awards one after another in several kinds of competition.Actually I began to make up a dream of becoming a famous singer in the future.
As time went byI came to realize that my dream wouldn't come true for there were strict conditions of being a singer.But I still took singing as my speciality since I found in music the interests which were lost in the exams.When I put all my emotion into singing a songit gave me very good and very pleasant feelingsand a good chance to relax.Besidesit was a good way to learn things that couldn't be easily found in life.
Now as I'm saying goodbye to my childhood my voice has changed into a deep male voiceand therefore I can sing a lot of songs written for adults.I am often deeply movedby the melody or by what the song writers said.I can feel that these words come from the bottom of their hearts:"All my best memories come back clearly to me.Some can even make me cryjust like before.It's yesterday once more.Heal the worldmake it a placefor you and for me and the entire human race".When I sing these songstears well up in my eyes.
I love singingand the most warm and fragrant thing in lifeI assumeis sitting in the sunshinelistening-to the walkman and singing together with the singer.
Sothis is my specialityand I hope every one of us can enjoy his own specialityen joy the simplegood things of life.
Goodmorning/afternoon,everybody!A famous American poet says , "Life is short, study is long." Everyone should work hard and study well. Never waste any time. Now we are young, we have so many things to do. Youth time is like a happy bird. If it flew away, it would never return. Nothing is more important than time.
Today some students spend too much time enjoying their lives such as eating, clothing, traveling and so on. Others spend too much time reading some useless books. A lot of time has been wasted. They have no idea that waste of time means wasting of one’s life.
While we are young and full of energy, let’s study hard.
My speech is over ! Thank you.
大家早上/下午好。美国一位著名的诗人说，"生命不息，学习不止。"每个人都应该努力工作，好好学习。不要浪费时间。现在我们正年轻，我们还有很多事情可以去做。青春是像一只快乐的小鸟。如果它飞走了，它就再也不会回来。没有什么比时间更珍贵。
今天，一些学生花太多的时间享受他们的生活，如饮食，服装，旅游等。而一些人读了很多没用的书。已经浪费了很多时间。他们不知道浪费时间就是浪费自己的生命。
我们年轻，充满活力，让我们努力学习。我的演讲到此结束！谢谢！
Though PE class is a part of children’s education, many teenagers didn’t form the habit of doing exercise, they don’t have interest in sports. Enthusiasm for sports is of great importance, young people should treat it as their integral part of education.
On the one hand, promoting enthusiasm for sports among teenagers helps them keep a healthy lifestyle. In the school, students are forced to take exercise in the PE class, they need to join certain activities. In this way, students live in a healthy lifestyle, they won’t get sick easily. But after they leaving school, no one forces them to do so, so they are lazy to take exercise, their bodies gets weaker.
On the other hand, the enthusiasm for sports can help students enhance their sense of teamwork. As we known, most sports need more than one person to do, like badminton and table tennis, these sports needs more than two people. When students are playing badminton, they need to cooperate, so that they can defeat others, if they just keep an eye on themselves, they game can’t be played. Doing these sports will bring students the sense of teamwork, which is important for their career.
Yet the vows of this Nation can only be fulfilled if we in this Nation are first, and, therefore, we intend to be first. In short, our leadership in science and industry, our hopes for peace and security, our obligations to ourselves as well as others, all require us to make this effort, to solve these mysteries, to solve them for the good of all men, and to become the world's leading space-faring nation.
We set sail on this new sea because there is new knowledge to be gained, and new rights to be won, and they must be won and used for the progress of all people. For space science, like nuclear science and all technology, has no conscience of its own. Whether it will become a force for good or ill depends on man, and only if the United States occupies a position of pre-eminence can we help decide whether this new ocean will be a sea of peace or a new terrifying theater of war. I do not say that we should or will go unprotected against the hostile misuse of space any more than we go unprotected against the hostile use of land or sea, but I do say that space can be explored and mastered without feeding the fires of war, without repeating the mistakes that man has made in extending his writ around this globe of ours.
There is no strife, no prejudice, no national conflict in outer space as yet. Its hazards are hostile to us all. Its conquest deserves the best of all mankind, and its opportunity for peaceful cooperation many never come again. But why, some say, the moon? Why choose this as our goal? And they may well ask why climb the highest mountain? Why, 35 years ago, fly the Atlantic? Why does Rice play Texas?
We choose to go to the moon. We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too.
It is for these reasons that I regard the decision last year to shift our efforts in space from low to high gear as among the most important decisions that will be made during my incumbency in the office of the Presidency.
In the last 24 hours we have seen facilities now being created for the greatest and most complex exploration in man's history. We have felt the ground shake and the air shattered by the testing of a Saturn C-1 booster rocket, many times as powerful as the Atlas which launched John Glenn, generating power equivalent to 10,000 automobiles with their accelerators on the floor. We have seen the site where five F-1 rocket engines, each one as powerful as all eight engines of the Saturn combined, will be clustered together to make the advanced Saturn missile, assembled in a new building to be built at Cape Canaveral as tall as a 48 story structure, as wide as a city block, and as long as two lengths of this field.
Within these last 19 months at least 45 satellites have circled the earth. Some 40 of them were made in the United States of America and they were far more sophisticated and supplied far more knowledge to the people of the world than those of the Soviet Union.
The Mariner spacecraft now on its way to Venus is the most intricate instrument in the history of space science. The accuracy of that shot is comparable to firing a missile from Cape Canaveral and dropping it in this stadium between the 40-yard lines.
Transit satellites are helping our ships at sea to steer a safer course. Tiros satellites have given us unprecedented warnings of hurricanes and storms, and will do the same for forest fires and icebergs.
We have had our failures, but so have others, even if they do not admit them. And they may be less public.
With the spread of the consciousness of environmental protection， the word “low-carbon” has been very popular in life。 We can find it in many aspects， such as low-carbon products， low-carbon consumption， and low-carbon travel and so on。 Generally speaking， more and more people are advocating “low-carbon” lifestyle。
随着环境保护意识的传播，“低碳这个词在生活中变得很受欢迎。在许多方面都能够找到它，如低碳产品，低碳消费，低碳旅游等。总之，越来越多人提倡“低碳”生活方式。
As implied in the name， “low-carbon” lifestyle is a kind of new pattern of lifestyle which aims to lowering the carbon dioxide emission in living as much as possible。 For example， some office workers are not proud of driving private cars from work to home any more but pride themselves on riding or taking public transportation。 In addition， they advocate recycling water and saving energy as much as they can。
就像名字暗示的那样，“低碳”的生活方式，是一种旨在尽量降低生活中二氧化碳排放量的新型生活方式。例如，一些上班族不再以开私家车上班回家自豪，而是骑车或乘坐公共交通工具而感到骄傲。此外，他们提倡循环用水，尽可能多的节俭能源。
As college students， we also make some contribution in our daily life to reduce the emission of the carbon dioxide。 For example， switch off the light when leaving and save water。 In addition， we should use our knowledge and action to arouse others’ concern about the importance of lowering emission of carbon dioxide and lead them to lead a “low-carbon” life。
作为大学生，在日常生活中我们也做了一些贡献来减少二氧化碳的排放。例如，在离开的时候关灯，节俭用水。并且，我们应当利用我们的知识，采取行动来引起别人对降低二氧化碳排放的重要性的关注并引导他们过“低碳生活”。
What can I do for our environment?
Everyone can do something for our environment。 For me， I should try to save electricity in my daily life。 For example， if I am the last person leave the classroom in the evening， I will always remember to turn off the lights。 In order to protect our forests， I will use paper wisely。 I should try to use both sides of paper whenever it is possible。 I will not use things like paper cups and disposable chopsticks because they are made of wood。 I believe that doing all these small things will improve our environment and help make our world a better place to live in。
The Power of a Smile
we are busier and busier now. sometimes we just feel stressed and painful and we forget to smile. please smile! smile to others around you. smile to the world!
smile is important in our life. for ourselves, smile can make us happy and relaxed when we are sad or stressed. when you smile, the world in your eyes are better.for others, smile can make others feel comfortable and relaxed and they will like you.
also, smile can bring you success. i once read a story. a salesman tried his best to sale things but always failed before. then he learned how to smile. he smiled all the time and others felt he was so kind and his smile was so attractive that they all wanted to but his things. finally, the man became successful.
no matter you are happy or sad, do it now. the power of a smile is large. it can make all of us feel happy including yourself. smile to the world, to others and to everything.
The main disadvantages are: some of the young people are too obsessed with the network control poor, it will trap into the network. Relevant data show that young people indulge in network performance is more than 89 percent plummet. Online games will have a strong young vanity has led to some young people have an unhealthy psychological, severely hampered the normal development of young people. There are fighting games so that some young people think that real life can be like a virtual network of the world as ruled by the law of the jungle to the world today, leading toward the path of crime. Play the role of those villains, so that boys like girls change, but it's like boys girls. The trap of the second network, some people because of social discontent, the network's own desire to radiation, leading to others on the network by fraud, deceived many examples, list goes on.Many benefits, save time and effort before the provincial lesson entirely on hand-written, time-consuming and laborious, much more will have to modify. Preparation of a computer is now "semi-automatic", and the school to teach all the prior knowledge input into the computer, after layout, modify, save, and finally print it out; the same can also copy the link. Computer is time-saving, labor-saving good helper, it gives me more time to study materials, the design of better teaching methods.
To be sure, we are behind, and will be behind for some time in manned flight. But we do not intend to stay behind, and in this decade, we shall make up and move ahead.
The growth of our science and education will be enriched by new knowledge of our universe and environment, by new techniques of learning and mapping and observation, by new tools and computers for industry, medicine, the home as well as the school. Technical institutions, such as Rice, will reap the harvest of these gains.
And finally, the space effort itself, while still in its infancy, has already created a great number of new companies, and tens of thousands of new jobs. Space and related industries are generating new demands in investment and skilled personnel, and this city and this state, and this region, will share greatly in this growth. What was once the furthest outpost on the old frontier of the West will be the furthest outpost on the new frontier of science and space. Houston, your city of Houston, with its Manned Spacecraft Center, will become the heart of a large scientific and engineering community. During the next 5 years the National Aeronautics and Space Administration expects to double the number of scientists and engineers in this area, to increase its outlays for salaries and expenses to $60 million a year; to invest some $200 million in plant and laboratory facilities; and to direct or contract for new space efforts over $1 billion from this center in this city.
To be sure, all this costs us all a good deal of money. This year's space budget is three times what it was in January 1961, and it is greater than the space budget of the previous eight years combined. That budget now stands at $5,400 million a year--a staggering sum, though somewhat less than we pay for cigarettes and cigars every year.
Good morning/afternoon/evening, my name is__X . It is really a great honorto have this opportunity/chance to introduce myself. I would like to answerwhatever you may raise, and I hope I can make a good performance today.

Eyes are the windows of the soul! Children rely on their eyes to feel and recognize the world. If there is something wrong with their eyes, it will not only make the window no longer bright, but also affect their life.
Hello, teachers and students. Red scarf radio station is here to meet you again. Im Yang Nan, the host of this program. Today, Id like to learn with you how to protect our pupils eyesight.
1. We should use our eyes scientifically
1) Reading and writing posture should be correct: when reading or writing, the best distance between eyes and books is about one foot! For this reason, the height of the table and chair should be matched properly, high chair low table or low chair high table are not conducive to eye health. Dont tilt your head when you write; Dont read books or newspapers on the way of walking, taking a bus or taking a boat.
2) Reading and writing time should be appropriate: reading, writing, drawing and other eye time is too long, easy to make eye muscle fatigue, leading to myopia. So read and write a little
When about, should go to the outdoor overlooking or sports for 10 minutes, this is to eliminate eye muscle fatigue, prevent myopia effective method.
3) Reading and writing light should be sufficient: sufficient light is an important aspect of maintaining normal vision, not in too dark light reading and writing, such as dusk, darkroom, etc. When reading and writing at night, the light should not be too dark, shaking or dazzling. The light should come from the front left to avoid the shadow blocking the line of sight. Do not read or write in strong light (such as sunlight or dazzling light), and do not read in flower shadow, so as to reduce the adjustment burden of intraocular lens and ciliary body.
4) Watch TV time can not be too long: TV is a dynamic picture, watch too long, most likely to lead to eye muscle fatigue, causing myopia. Therefore, the time of watching TV should not be too long, generally controlled within 2 hours, and every 30 minutes, at least 5 minutes rest, so that the eyes get rest. The distance to watch TV should be appropriate, generally 2 meters away, and the angle should not exceed 45 degrees. In the room watching TV, there should be a certain brightness of lighting. You can turn on a small lamp, but the light can not directly shine on the fluorescent screen or eyes. Its better to put it behind or beside. When debugging the TV, the jumping picture on the TV screen is very harmful to the eyes. Close your eyes to avoid stimulation. Play less with computers and mobile phones.
2. Insist on doing eye exercises
Do eye exercises is an effective way to prevent myopia, should persevere every day. If you are not a scholar, you can gently massage the upper and lower eyes, or close your eyes to help you recover from eye fatigue. Once in the morning (after getting up), once in the middle (before eating) and once in the evening (before going to bed).
3. We should form good living habits
Strengthen physical exercise, advocate outdoor activities, often bask in the sun, breathe fresh air. Life should be regular, get up early and go to bed early, keep enough sleep and rest properly. Pay attention to nutrition, not partial to food, do not eat snacks, eat more vegetarian and vitamin rich food and calcium food, such as pig liver, milk, eggs and so on. We must often go to outdoor activities and nature to feel different colors.
4. Check your eyesight regularly
Do vision examination regularly, and adjust and improve the study and living habits according to the results of vision examination.
5. A convenient way to prevent
Cassia obtusifolia: fried, instead of tea, often take effective.
Students, do you remember? I hope that in the future life and study, we can form good habits to protect our eyesight.
Todays red scarf radio station is going to say goodbye to you. Well see you next week at the same time.
Leifeng was known as a pattern that offered help to others selflessly. He devoted all this life into his beloved career as well. I, myself, was totally shocked by his character.
Such is human nature; people trace the good, water flows to low. Everyone should copy his sprit as our daily life goes instead of uttering a meaningless slogan “learn from Leifeng, our decent idol”, so that we could definitely see a lot more smiling faces rather than conflict.
To help others is not a hard thing, however, what you need is to consist doing it. Take myself as an example. I am the representative of Math, to collect homework is my daily task, however, I would turn them to the right page for shorten the time for teachers when correcting them.
I strongly propose that we shall see a better world if each of us treat Leifeng as our model and copy his spirit.
Recently， a popularserioushot topic es into the eyes of our universal bodies as the cartoon depicts。 From the picture， we can see that a middle-age housewife， perplexed and terrified， is picking out her daily diet from a pile of undesirable things， such as illegal-cooking oil， fruits with excessive pesticide and the like。
It seems that there are many factors can be mentioned and accounted for this kind of case， and in my perspective， the followings are the obvious and have a far-fetching influence。 On the one hand， the merchants in an increasing number are aiming at maximizing their profits with the minimal principal in the wider ranges of petitive and more open social background。 On the other hand， it is the inplete system of law that has less supervision of the producing and processing of modities。
Considering all the points discussed， it is highly sensible that we should take prompt measures to resolve this problem。 In the first place， more bettering policies should be brought forward。 In the second，more moral schooling should be applied in all munities。 Only by enforcing these measures， can we effectively， efficiently， and eventually solve the problem。
