1 Maintaining our health is very important. By doing this well we will be able to participate in the socialist construction of our country. No one should trifle with one's health. Since youth is the time for physical development, we must do strenous physical training every day in order to have a strong physique and enjoy vigorous health.
In physical training, perseverance is a primary necessity. We must struggle against our own laziness and stay with our training. It is also important to select suitable exercises and then to do them in an orderly way, step by step. Of course, if we enjoy the exercise we will perform more persistently.
Besides, it is a known fact that physical training, such as long distance races, can also generally strengthen our perseverance. Dear friends, especially those with health problems, come out to the playground and take part in physical exercise.
保持健康非常重要。锻炼好身体，我们就能够参加我国的社会主义建设。没有任何人不重视自己的健康。由于青年是长身体的时期，为了有一个强壮的体格和享有健康，我们必须每天刻苦锻炼。
在体育锻炼中，坚持不懈非常重要。我们必须同我们自身的懒惰作斗争，坚持锻炼。选择适合自己的锻炼方式，然后有条不紊地、循序渐进地锻炼是重要的。当然，如果我们喜欢某项运动，我们就会坚持不懈。
另外，众所周知像长跑这样的体育锻炼也可增强我们坚持不懈的精神。亲爱的朋友，特别是身体不好的朋友们，走出家门到操场上去参加体育锻炼吧。

For thousands of years, physical activity has been associated with health. Today, science has confirmed the link, with overwhelming evidence that people who lead active lifestyles are less likely to die early, or to experience major illnesses such as heart disease, diabetes and colon cancer.
Exercise benefits every part of the body, including the mind. Exercising causes the body to produce endorphins, chemicals that lead a person to feel peaceful and happy. Exercise can help some people sleep better. It can also help with mental health issues such as mild depression and self-esteem. Plus, exercise can give people a real sense of accomplishment and pride at having achieved a certain goal - like beating an old time in the 100-meter dash.
Exercising can help you look better, too. People who exercise burn calories and look more toned than those who don't. In fact, exercise is one of the most important parts of keeping your body at a healthy weight. When you exercise, you burn food calories as fuel. If a person eats more calories than he or she burns, the body stores them away as fat. Exercise can help burn these stored calories.
Finally, exercising to maintain a healthy weight also decreases a person's risk of developing certain diseases, including type 2 diabetes and high blood pressure
3 From Monday until Friday most people are busyworking or studying, but in the evenings and off weekends they are free to relax and enjoy themselves. Some watch television or go to the movies;others participate in sports.It depends on individual interests. There are many different ways to spend our spare time.
Almost everyone has some kind of hobby. It may be anything from collecting stamps to making model airplanes.Some hobbies are worth a lot of money; others are valuable only to their owners
I know a man Who has a coin collection worth several thousand yuan. A short time ago he bought a rare ten-yuan piece worth 250 yuan. He was very happy about the purchase and thought the price was reasonable, on the other hand, my son collects match boxes. He has almost 600 of them but I doubt if they are wortfi any money. However, to my son they are extremely valuable. Nothing makes him happier than to find a new match-box for his collection.
That’s what a hobby means, i guess. It is something we like to do in our spare time simply for the fun of. it. The value in money is not important, but the pleasure it gives us is.
4 The internet is an extremly important thing in our lives now. We get a lot of information from the internet. It is a very efficient tool.
I like surfing on the internet very much. I could usually find useful knowledge that teaches me a lot. I could listen to music. I could download useful resources. Internet surfing is also useful when I am doing research. There is just too much useful information on the internet.
The internet has changed my life. I have learnt a lot from the internet. Sometimes, when I'm confused, I could go on the internet and find the answer. Sometimes, when I feel lonely, I could go on the internet and make friends. The internet is really a place that can change people's lives.
Right now, technology is growing extremely fast. It is developing so fast that new inventions almost come out daily. The internet had been a slow, restricted area that only businessman used. Now, things like peer-to-peer technology developed and the internet is running much faster. All of us are familier with the internet. I think that the internet will even grow more advanced. It could become faster and more reliable. It will become an important aspect for us the success!
After all, the internet is very important. Being cut off from the internet would be a horrible experience. The feeling of isolation was inconvenient. We all know that the internet is inextricably bound to our lives
5 The earth scale change of climate has brought a new kind of natural disaster and the developed and complicated city system is holding a latent risk of expanding the damage artificially. Also people has been spoiling the health since the immense quantity of chemicals have been produced and already used in pursuit of convenience and various toxic substances have been produced unintentionally and accumulated in environment. Therefore, We need some countermeasures from the viewpoint to prevent the city environment form disaster and to manage environmental risks. So we will develop and improve a new risk management system and a disaster prevention system to preserve and create the city environment where people feel easy and sound in their life.
6 Once man did not have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be unlimited.
Today things are different. The world has become too crowded. We are using up our natural resources,and polluting our environment with dangerous chemicals. If we continue to do this, human life on earth will not survive.
We realize that if too many fish are taken from the sea, there will soon be none left. Yet,with modern fishing methods, more and more fish are caught.We know that if too many trees are cut down, forests will disappear. Yet, we continue to use powerful machines to cut down more and more trees. We see that if rivers are polluted with waste products, we will die. Yet, waste products are
still put into rivers.
We know that if the population continues to rise at the present rate, in a few years, there won’t be enough food.What can we do to solve these problems?
If we eat more vegetables and less meat, there will be more food available. Land for crops feeds five times more people than land where animals are kept.
Our natural resources will last longer if we learn to recycie them.
The world population will not rise so quickly if people use modern methods of birth control.
Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future

9 As we all know, the culture and customs of a country are part of the country's spirit.It's certainly true
that different countries have their local customs.That is to say,it is necessary to accustom youself to the culture no matter where you go.
Culture is not only something in perception but also something in daily life.The defination of culture is various,including folk music,native languages and so on.Here is my description of Chinese culture,which may be quite familiar to us.
Chinese culture is the product of a long history,therefore,it is still a mystory in the eyes of foreigners.For example,the Spring Festival is the most popular festival in China,and we celebrate it both for fun and for spiritual fulfillment.
That's all.However,if you want to enrich yourself with more about culture and customs,you'd better explore more and think more in everyday life.
10 保存习俗( Keeping Customs) When people move to another country, they not only face a different environment and language, but also different customs. Every culture has its own customs, and all of them aver valuable. However, deciding how to deal with the problem of unfamiliar customs is a challenge for many immigrants. Some choose to follow the customs of their new country, while others prefer to adhere to their own customs. Each of these choices has some advantages as explained below. When people choose to follow the customs of their adopted country, they may find that it helps them to adapt more quickly to the new society. They have something to discuss and share with their new neighbors, and sharing customs is one way for people to feel closer to one another. Thus, following the new customs may help immigrants feel more at home. It may also help them to see the positive things in their new environment and do forget their feelings of homesickness. On the other hand, those who choose to continue following their own customs may also find that it helps them feel more at home. There are many things to adjust to in another country, and following their traditional customs may help people feel more secure in the new surroundings. More importantly, our customs are a part of us. They are an expression of the culture that has shaped us. This is something that most of us would like to pass down to our children and share with others. Sharing our old customs can also bring us closer to our new neighbors. To sum up, our customs have value and are an important part of our culture. Therefore, I don’t believe that we should abandon our traditional customs when we move to another country. At the same time, I believe that we should learn about the customs of our new home and follow those that appeal to us. In this way, we can remember and celebrate our old culture while adapting to our new one
