Sport is something that everyone can enjoy. It can be played by individuals and as a team.
there are many type of sport, the most common ones are basketball, tennis, table tennis, netball, swimming and a lot of others that i can't possibly name.

The reason why sport is so popular for all age groups is because Sport help us to a healthier and fitter body and life.
Everyone wants to stay health and fit, so they won't be sick very often. Sport always help our body function properly and build muscles.

SO come on and have fun!
ladies and gentlemen,
i have had a lot of teachers in my school who have given me much help in my study.
for their help i will never forget them.
but today i am going to talk about a special teacher of mine.
this teacher is not a human being and its name is“computer”.
it has been teaching me a lot of knowledge and i appreciate it very much.
with the development of modern science and technology, computers are widely used in every teritories (1) including education.
how can a computer be my teacher? how does a computer teach me? multimedia(多媒体)helps a lot in this aspect in recent years, and computer-based training (cbt) has become a popular educational medium (手段).
even before the multimedia come (2) up, many different learning systems appeared, using the components and techniques we now associate with the term “multimedia”.
multimedia components, such as graphics (动画) , animations , sound and video, make the learning process easier through visualization.
animations can present many complex subjects dynamically, but human teachers can not do this on blackboards.
multimedia makes our study more lively and interesting.
for example, a cd-rom disk named “encarta encyclopedia” contains 650 mb information including images, graphics, music clips, video clips, animations , texts, hotwords, and database search functions.
fields involved includes physical sciences, performance arts, social sciences, politics, military, education and so on.
when pressing a button, i can hear american president clintons speech clip.
i may enjoy playing all kinds of musical instruments in the world.
i can also see the animation of many physical phenomena.
this makes physical concept to be understood deeply (3).
the audio features of multimedia can greatly help me learning (4) foreign languages.
with its speech output capabilities, im no longer dependent on an instructor for proper pronunciation.
how can i interact with a computer? there are many ways, including keyboard, mouse pointer, and touch screen.
i often use a keyboard.
when i press right keys, i can see and hear whatever i want.
information world is at my fingertip.
i wish that true speech input-output system would be invented one day.
as teachers, computers have a lot of virtues： they are positive, they have good memories and never lose any information stored in them.
As you know, there are four kinds of pollution. They are air pollution,water pollution, waste pollution and noise pollution. But what can we do tosolve the pollution? I think, firstly, we can make cars that don’t pollute theenvironment. We can ask companies to use modern clean technology. In some bigcities, we can limit the number of cars. Secondly, we can try to use less waterand make sure that we do not pollute the water. We can tell factories that theyare not allowed to pour waste water into the lakes and rivers. Thirdly, weshould not throw rubbish in parks and cities. We can pick up rubbish if we seeit. We can put more rubbish bins in our parks and cities. Fourthly, we can livefar from the noise and make the laws to limit the noise.
The air, water and the whole atmosphere directly influenced our lives, suchas the air, people may cough and it will lead to cancer. So we must try our bestto keep the world clean and tidy. To reach it, I want to put forward threepoints to everybody---Point 1: don’t spit and liter; Point 2: don’t draw on thewall; Point 3: clean the streets every day.
In order to make the environment clean, let’s join our hands together tomake the world better.
Thank you!
