— That's the reasons why so many people go to work by bus instead.

    Computers are useful machines. They can help people a lot in their everyday life. For example, they can help people save much time, and they can help people work out many problems they can't do easily. Our country asks everyone to learn to use computers except the old people.

    Today more and more families own computers. Parents buy computers for their children. They hope computers can help them improve their studies in school. Yet many of the children use computers to play games, to watch videos or to sing Karaoke, instead of studying. So many teachers and parents complain (抱怨）that computers cannot help children to study but make them fall behind. So these parents lock computers in the boxes.

In some other countries, even some scientists hate computers. They say computers let millions of people lost their jobs or bring them a lot of trouble.

Will computers really bring trouble to people or can they bring people happiness? In fact, people can decide it by themselves.

    The computers changed our lives in the 1980s, the Internet changed our lives in the 1990s, and the robots will change our lives in the new century.

    Do you think there will be robots in people's homes? It's not a dream that every home will have a robot.

    Now, robots are not only able to help people do the housework, they can also help the doctors do the difficult operations, play chess with people, play the piano and so on.

    A new cooking robot is used in Beijing. It can cook all the dishes on the menu; you only need to wait two to four minutes. In the future, the robot will be a nurse, a security (安全）guard, or a partner in your life.

    Experts believe robots will be used everywhere from the industrial (工业的） robots to service robots. In the future, robots will become part of the family, and provide close service for people. We all look forward to the new robot age.

    Have you ever seen a horse with toes? Millions of years ago, horses had many toes. They had four toes on each front foot. They had three toes on each back foot. The horses were no bigger than cats.

    These small horses lived in the forest. Their many toes helped the horses run over the soft, wet ground.

    It was very hot in the forest. But the weather changed. It became cold. Many trees could not live in cold weather. The trees died and fell. Open fields took the place of forests. The sun made ground dry and hard.

    Horses began to change, too. They began to get bigger. This took a long time. On the dry, hard land, horses needed only their middle toes for running. Their middle toes became hard. After a long while, horses had only one hard toe on each foot. We call this hard toe a hoof.

    Long long ago, there was a man who lived in a village. One day, he went to a market and did some  (shop). He  (sudden) found two boxes. Both the two boxes  (be) very beautiful and the man fell in love with them at the first sight. So he bought them.

    After he got home, he didn't know how to use the two boxes. He thought it over and decided to do something  (specially). He decided to put all of his happiness in the yellow box and all of his sadness in the black box. He thought that it was funny to do that.

A few days  (late), the yellow box was very heavy,  the black box was still light.

    He didn't know . He decided to open the two boxes and found out the   (true). He opened the yellow box and found nothing. Then he opened the black box and saw  hole at the bottom (底部).

    Then he smiled to  and said, “Happiness is for me. Let sadness go.”
