In recent years the number of private cars has been increasing rapidly in our country. In 1990, there were about one million private cars. As time went on, the number of private cars went up to 5 million in 1999. Now there are more than 10,000,000 private cars in China.

　　　 As we know, a car is very convenient. We can go to any place more quickly. Besides, the increase of the number of private cars can help car industry develop faster.

　　　 However, more cars may cause more traffic accidents and more air pollution. What’s more, waste gases from cars can do great harm to our health.

　　　 I do hope people will pay enough attention to these problems.

　　　 Air travel has two advantages over train travel. First, it can save much time. We can fly from Beijing to Guangzhou just in two hours, but by train, we have to spend 24 hours or more. Second, air travel is more comfortable, because the plane flies so smoothly that we rest well during the trip, while the train is crowded sometimes and passengers have to sit for a long time, which makes them tired. But the train travel also has advantages. For example, traveling by train costs only 250 yuan while traveling by air will cost us 900 yuan. Besides this, through the train’s windows, we can enjoy views of many big cities such as Jinan, Zhengzhou, Wuhan and Changsha. So I think different people like different ways of traveling.

　 People often consider misery and setbacks as terrible as monsters. But hard times will offer new ways of looking at life, and strengthen our willpower. As Charles Dickens, a famous English writer, once said, “Minds, like bodies, will often fall into an ill-conditioned state from too much comfort”.

　 People admire those successful men, but I think their spirits that overcome the setbacks bravely are more inspiring, such as the famous Harvard Girl – Liz Murray. She lived in an unlucky family, for her parents were both addicted to drugs. She was the only member of the family who had a job. It was the strong willpower that helped her. Also, it was her willpower and determination that led her to success. So Liz Murray was a winner in this fight.

　 No one is always lucky in the world. When facing setbacks, we must become much braver than ever. Where there are setbacks, there are a lot of brave fighters.

Smoking Does a Lot of Harm

　　 If you look in some public places, you will see that most smokers are young people, even middle school students. It is said that in China smokers’ number is about 45 percent of the population.

　　 Why do so many people smoke? Some think that smoking is a pleasure. Some believe that they can refresh themselves by smoking.

　　 In fact, smoking is a bad habit. It does great harm to people’s health. Studies of smoking shoe that many kinds of diseases are related to smoking. Smoking itself is a waste. It costs one so much money. Besides, many fires are often caused by careless smokers.

　　 Today, more and more people all over the world have begun to give up smoking. If you are not a smoker, don’t start.

Learning English Is of Great Importance

　　 Learning English is very important. English is widely used all over the world. It is often used in the international meetings. Most business letters are written in English. With the help of English we can learn modern science and technology from the developed countries. We can also introduce our achievements and experience to other countries.

　　 Because of its importance, English is a required subject in high schools and colleges.

　　 Now many people are working hard at English. It is very important to learn English well. If we learn English well, we can serve our country better. English is very useful in the socialist construction.

　　 I have a different point of view on “People should not be allowed to play radios in public places”.

　　 It is known that many people obviously enjoy listening music in the open air and we have no right to interfere with their enjoyment. Those who do not like the music or many other kinds of programmes may move away. On the other hand, as we know, most of the people want to keep in touch with the news from both at home and abroad.

　　 The noise from air planes is quite different for it does not produce pleasure or information.

　　 Therefore, in my opinion, it does not matter that people play radios in public places.

Getting up early can help you to be healthy. The air in the morning is fresh. If you breathe such air, it does you a lot of good. You can have some sports, too in the morning. This can make you stronger.

The fresh air and quietness in the morning make you think more quickly than any other time of the day and memorize what you have learned easily. Another reason for you to think quickly and memorize things easily is that you have taken a long rest during the night.

Getting up early can also help you to train your character. Some students can get up early, but some can not. This needs perseverance.

There is a saying in English, “Early to bed, and early to rise makes a man healthy, wealthy and wise.” This is very true. I hope everyone will form the good habit of getting up early.
