     We all know that as the population of a city grows, so do its problems.
Pollution,  too  many cars, and crowded streets are just a  few of these
difficulties.  One way to help with these problems is city trains. Trains
traveling to different parts of a city means fewer cars and buses on our roads, cleaner air, and more open streets. In recent years, cities such as Guangzhou, Shenzhen and Shanghai have all built city train lines.
     The first city train line in China was built in Beijing. The oldest part of the train line, from Beijing Stop to Pingguoyuan, was opened in 1969.  Its length was 23.6 kilometres. As the city grew after 1980, so did the need for more
trains.A newer train line was built to help move people around the city centre. The 16-kilometre-long "circle line" was finished in 1987. Since that time
even more train stations have been built and today the train lines in the city
are over 50 kilometres long.
    For  the  coming beautiful  future,  the trains of Beijing will be very
important.  We all know that most of the people who go to work or go to
school will travel by train.

Do you like to sit in front of the computer and play computer games hour after hour? Have you ever thought of what that may be doing to your health? More and more children are becoming overweight(肥胖的) and growing less creative because they spend too much time in front of the computer according to a survey.
Last week Child Protective Services(儿童保护组织)in America organized an activity. The aim of the activity was to encourage children to do some outdoor activities instead of playing computer games at home. Many American children spend about 1,000 hours a year playing computer games — more time than they spend in school. As a result, they are overweight. Some of them have very poor eyesight, and they can’t see clearly.
Everyone should pay attention to his health and try to keep healthy. The doctor says that the longer children play computer games, the more overweight they may become. And the junk food children eat while they’re playing computer games makes the weight problem more serious.
To keep fit, children need to take exercise regularly, play outside with friends, and explore the world around them. Can you spend two weeks without playing computer games? It might be difficult for computer lovers, but why not have a try?
