It's 21:00 in Beijing now. Let's look at what the four students are doing.

Beijing is the capital of China. It is a very 1 city. Lots of people live and work there. It usually takes them a long2to get to work.

My friend Zhang Yu works in a company (公司) in Beijing. The company is3from his home. He goes to work either by bus 4 by subway. When he gets up early, he5the bus to work. His home is next to the first stop of the No. 456 bus. It is easy for him to get a seat (座位)6 the bus. But he spends (花费) two hours getting to the7. When he doesn't get up early, he takes the subway. It takes8 about one hour to go to work by subway. But there are too9people on it. Sometimes Zhang Yu can't even(甚至)10!

It is Zhang Yu's dream to buy a house near his company. Can his dream come true?

The Internet has changed the world, people are able to get and share information in seconds. Nowadays, people begin to wonder: Is the Internet good or bad? "It's impossible to answer that question because the Internet means so many things," says psychologist （心理学家） Patricia Greenfield.

Some are truly wonderful. In many ways it makes life easier and simpler. It helps us get things done more quickly. It opens up the world to us. And if a friend lives far away, the Internet makes it easy to stay in touch.

However, the issue （话题）    isn't black and white. Some can become real problems if we don't take care. Spending too much time online is bad to people's health. It may even cause them to be less social with family and friends. Aside from that, some people attack the web or use the Internet to steal others' personal information, even banking information. Most of the young students think the Internet is simply an icon （图标） on the screen（屏幕）. Kids won't realize that the Internet is a network of millions of computers until about 10 years old.

The Internet can be a useful tool, but don't let it take up all of your time. Use the Internet properly and carefully and it can make your life more colourful.
