20、阅读以下文字,给“知识经济”下个定义。(3分)以前的经济以传统工业为支柱,以稀缺自然资源为主要依托。而知识经济则以高技术产业为第一产业支柱.以智力资源为首要依托。因此,“知识经济”是一种可持续发展的经济,它是一种新型的经济。知识经济是_______________________________________。

Life today is much easier than it was hundreds of years ago, but it has also brought new problems. One of the biggest is pollution. Pollution comes in many ways. We see it, smell it, drink it and even hear it.The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. Man is now slowly polluting the whole world..Air pollution is still the most serious. It’s bad to all living things in the world. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us become angry more easily.Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city.The pollution of SO2 is now the most dangerous problem of air pollution. It is caused by heavy traffic. It is sure that if there are fewer people driving, there will be less air pollution.( )30. Which of the following is NOT TRUE A. Many countries are making rules to fight pollution. B. The pollution of the earth grows as fast as the world’s population does. C. From now on, maybe people should try to go to work by bus or bike instead of car or motorbike. It is helpful to fight against the problem of SO2. D. The problem of pollution is not so serious because there are so many peopleBPeople like to say:“The hand that rocks(摇动)the cradle(摇篮)rules the world.”Or theysay:“Behind every successful man,there is a woman.”Now some women still like making their husbands and sons successful.But some womenwant more for themselves.They want to be successful as men.Today the best jobs are still given to men.Even when women do the same work,they areoften paid less than men.Some women want these things changed.They want to stand beside the men,with the same chances for success.Now many American women are earning money outside their homes.More than half of thewomen at the age of eighteen to sixty-five have good jobs.In general,working women have more education than those who stay at home.Among women with jobs,eight out of ten drive a car to work,and most of them often spend their holidays away from home.They like traveling by air.Women’s work has made several changes in women’s lives and in men’s lives,too.But things are quite different from those in the Middle East countries.In the Middle East countries,women have to stay at home.They look after their families and do all the housework.They can’t find work outside.When they go out in public.they cover their faces with something and walk behind their husbands.For the past few years the women’s life has been changing in those countries.Many women want to play an active role in the society.Though working gives them few chances of getting married,many men still want to marry them in the old ways.( )31.More and more women want to get jobs because .A.they don’t want to stand behind their husbands in the streetB.they think they are more important than menC.they think they are as important as menD.housework troubles them too much( )32.Some women are still badly paid .A.because women want more money B.because of the old ways of thinkingC.because women can’t do as well as men do D.but we don’t know why21世纪教育网CEveryone needs friends. Friends bring us happiness and hope in our lives. But the ability to make friends changes from person to person. To some people, making friends is easy, and to others it’s very difficult.[来源:21世纪教育网]Making friends is a skill, and the first thing is to know how to get on with others.If you have trouble in making friends, maybe I can tell you how to do it. Realize your own good points. You have skills and talents(才能) that others will like. Believe that you are a good person and have something nice to share with others. Be humourous. Learn to laugh at yourself and your weakness. Remember to smile at others. Respect the others. Everyone has his own idea. Learn how to listen to others’ ideas without trying to make them accept yours. Be kind. If you are kind to others, they will usually be kind to you. There are hundreds of little things you can do to show your kindness. Open the door for someone. Wave to a friend and so on. Don’t complain(抱怨). Learn to accept what you can’t change, and work hard to change what you can. No one is willing to hear your complaints all the time. Never give up. Even if you are faced with some closed-minded people, never give up. And try to find someone who will understand you.( )36. Why do we need friends according to the passage A Friends can do everything for us. B Friends can bring us happiness.C Friends accept our ideas all the time. D Without friends, we could not live.A Respect others. B Complain. C Give up. D Laugh at themDThirty years ago, Lake Ponkapog in Hartwell, New Jersey, was full of life. Many birds and animals lived beside the water, which was full of fish. Now there are few birds, animals, and fish. The lake water is polluted. It is in a colour of dirty brown, and it is filled with strange plants.How did this happen First, we must think about how water gets into Lake Ponkapog. When it rains, water comes into the lake from all around. In the past, there were forests all round Lake Ponkapog, so the rainwater was clean.Now there are many homes around the lake. People often use the chemicals (化学制品)in their gardens. They use other chemicals inside their houses for cleaning and killing insects. There are also many businesses. Businesses use chemicals in their machines of shops. Other chemicals fall onto the ground from cars or trucks. When it rains, the rainwater picks up all the chemicals from home and businesses and then carries them into the lake . They pollute the water and kill the animals.Boats on the lake are also a problem. Lake Ponkapog is a popular place for motorboats(汽船). But oil and gas from boats often get into the lake. So more bad chemicals go into the water this way.People in Hartwell are worried . They love their lake and want to save it. Will it be possible A clean lake must have clean rainwater going into it. Clean rainwater is possible only if people are more careful about chemicals at home and at other chemicals on the ground. And they mustn’t use motorboats any more on the lake. All these may change people’s lives. Only then can Lake Ponkapog be a beautiful, clean lake again.( )41.
