Can you make animals work for us? Some scientists think that one day we can teach animals to do a lot of things for people. In a film shown on TV, you may see elephants, monkeys, tigers or some other animals are always given a little food to eat after they have done something. Scientists say that people can teach many different animals to do some of the easy work if they know they will get something to eat. We all know elephants can carry large logs(圆木)，and dogs can look after houses. And we even teach animals to work in factories. In America, for example, people have used apes to help make cars and scientists think that those large monkeys may drive trains one day. Now people are trying to get them to do the same thing that man does.Scientists think animals can help people to do something _____ .
| A．if they know they will get food after doing something. |
| B．because animals are so clever. |
| C．if they know the work is easy enough |
| D．because most animals are friendly to man |
_______ can do some heavy work because they are so strong.
| A．Tigers | B．Elephants | C．Monkeys | D．Dogs |
What does the underlined word “apes” mean in Chinese?
| A．猎豹 | B．猿猴 | C．孔雀 | D．狮子 |
Scientists are planning to make big monkeys to________.
| A．make trains | B．carry logs | C．drive trains | D．work at school |
If we teach animals carefully, ________.
| A．some animals can do the same things as man does. |
| B．all the animals can work for us. |
| C．many animals can do all the work as we do. |
| D．we may get many animals to work without giving them food. |

Someone is singing next door, but you feel unhappy because her singing is terrible. So you think she is just making noise. We know that too much noise makes people feel terrible.
Scientists are still trying to find out more about noise, but already it is known that a noise of over 85 decibels(分贝) can make some people tried and anxious(焦虑的).
In the past we thought only workers in very noisy places became deaf easily. Today, scientists believe that 10% of all workers in Britain become deaf in their work.
There are also new dangers from noise. Pop music, for example, can reach 120 decibels when it is played loudly five feet away! Only a plane can make such loud noise when it takes off.
There was an experiment in the United States. Some people would be given a lot of money if they stood below a jet when it was taking off over their heads. No one got the money after the jet flew past because all of them died in the noise.
People can’t pay their attention on what they are doing when there is much noise. Workers in noisy offices, for example, do their work more slowly than workers in quiet offices. Another study shows that workers in factories can do dull(枯燥的) jobs better when lively music is played for them.

Mrs. Baker’s sister was ill. She had someone to look after her from Monday to Friday, but not at the weekend, so every Friday evening Mrs. Baker used to go off to spend the weekend with her at her home in a neighbouring town. But as Mr. Baker could not cook, she had arranged (安排) for his sister to come over and spend the weekend looking after him at their home. This meant that Mr. Baker had busy time when he came home from work on Friday evenings. First he had to drive home from the railway station. Then he had to drive his wife to the station to catch her train. And then he had to wait until his sister’s train arrived, so as to take her to his house.
Of course, on Sunday evening he had to drive his sister to the station to catch her train back home, and then wait for his wife’s train, so as to bring her home.
One Sunday evening, he had seen his sister off on her train and was waiting for his wife’s arrival when a porter ( 搬运工 ), who had often seen him at the station, came over and spoke to him, “You are having a lot of fun,” he said, “ But one day one of those women is going to catch you with the other, and then you will be in real trouble!” Who was ill? ___________
| A．Mr. Baker | B．Mrs. Baker | C．Mr. Baker’s sister | D．Mrs. Baker’s sister |

We are all busy taking about and using the Internet. But how many of us know the history of the Internet?
Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks didn’t work well. If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way, computer network system would keep on working all the time.
At first the Internet was only used by the government (政府). But in the early 1970s, universities, hospitals and banks were allowed to use it, too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers became cheaper and easier to use. Scientists had also developed software that made “surfing” the Internet more convenient.
Today it is easy to get on-line and it is said millions of people use the Internet every day. Sending e-mails is more and more popular among students.
The Internet has now become one of the most important parts of people’s life.The Internet has a history of more than _________ years.
| A．fifty | B．ten | C．forty | D．twenty |
A new network system was set up to_______.
| A．make computers cheaper |

When we talk about how teenagers are getting worse and worse now, most young people don’t agree. Teenagers always say they are growing up. They can have part-time jobs. And they can even drive a car.
Their parents say, “Our children are very good. They like pop music and they play it in their own rooms. They help us in the house. You know they feel bored sometimes because there’s nothing interesting in the neighbourhood, no clubs, and no sports.”
A teacher says that he believes most young people are very kind. He thinks that it’s not bad for young people to like loud music because it can give them lots of energy and makes them feel excited. Also, a lot of young people work very hard at school, and they can get good jobs later.
Lewis, a sixteen-year-old boy said, “I have passed all my examinations but I can’t get a part- time job because older people always think I’ m lazy.”
In my opinion, a lot of teenagers are very kind. They belong to community(社区) work groups. They help old people, and they also volunteer in local hospitals or primary schools to help look after patients and younger students.
