letter on the Answer Sheet with a single line through the center.

Questions 21 to 25 are based on the following passage:

Some radio singals were heard in 1967.They were coming from a point in the sky where there was unknown star.They were coming very regularly,too:about once a second,if they were controlled by clock.?

The scientists who heard the signals did not tell anybody else.They were rather afraid to tell in case they frightened people.The signals were coming from a very small body—no bigger,perhaps than the earth.Was that why no light could be seen from it?Or were the signals coming from a planet that belonged to some other star??There was no end to the questions,but the scientists kept the news secret.“Perhaps there are intelligent beings out there.”they thought,“who are trying to send messages to other planets,or to us?So the news was not given to the newspaper.Instead,the scientists studied the signals and searched for others like them...Well,all that happened in 1967 and 1968.Since then scientists have learnt more about those strange,regular,radio signals.And they have told the story,of course.

The signals do not come from a planet;they come from a new kind of star called a “pulsar””.About a hundred other pulsars have now been found,and most of them are very like the first one.?

Pulsars are strong radio stars.They are the smallest but the heaviest stars we know at present.A handful of pulsar would weigh a few thousand tons.Their light—if they give much light—is too small for us to see.But we can be sure of this,no intelligent beings are living on them.

21. The radio signals discussed in this passage____.?

A.were regular B.were controlled by a clock?

C.were heard in 1967 only D.were secret messages ?

Questions 26 to 30 are based on the following passage:?

Over vast areas of every continent,the rainfall and vegetation necessary for life are disappearing.Already more than 40 percent of the earth's land is desert or desert?like.About 628 million people—one out of seven—live in these dry regions.In the past,they have managed to survive,but with difficulty.[ZZ(Z]Now largely through problems caused by modern life,their existence is threatened by the slow,steady spread of the earth's deserts.

Scientists still do not understand all the complex problems of the desert,but there have been many ideas for saving the land.Sandi Arabia has planted 10 million trees to help keep the sand from taking over fertile areas.The Israelis are again using some of the water collection systems left by the ancient people in the

Negev desert.They plan to water their orchards with the extra water.Some Sahel farmers still raise cattle on their poor farm land,but before the cattle are sold, they are taken to greener lands in the south to get fat.

A.The problem of spreading desert.?

B.The rainfall and vegetation in desert areas.?

C.Their life in the desert is threatened now by traditional problems.?

D.New water wells can solve the problem in Africa's desert. ?

Questions 31 to 35 are based on the following passage:

Telephone, television, radio, and telegraph all help people communicate with each other. Because of these devices, ideas and news of events spread quickly all over the world. For example, within seconds, people can know the results of an election in another country. An international football match comes into the homes of everyone with a television set.News of a disaster such as an earthquake or a flood can bring help from distant countries within hours, help is on the way. Because of modern technology like the satellites that travel around the world, information travels fast.

How has this speed of communication changed the world? To many people,the world has become smaller. Of course this does not mean that the world is actually physically smaller. It means that the world seems smaller. Two hundred years ago,communication between the continents took a long time. All news was carried on ships that took weeks or even months to cross the ocean. In the seventeenth and eighteenth centuries,it took six weeks for news from Europe to reach America.This time difference influenced people's actions. For example, one battle, or fight, in the War of 1812 between England and the United States could have been avoided. A peace agreement had already been signed. Peace was made in England, but the news of peace took six weeks to reach America. During these six weeks, the large and serious Battle of New Orleans was fought. Many people lost their lives after a peace treaty had been signed.They would not have died if news had come in time.In the past,communication took much time than it does now.?

There was a good reason why the world seemed so much larger than it does today.

31. News spreads fast because of____.?

A.modern transportation B.new technology?

C.the change of the world D.a peace agreement ?

32. According to this passage,____is very important to people in a disaster area.

A.fast communication B.modern technology?

C.latest news D.new ideas ?

A.The world now seems smaller because of faster communication.?

B.The world is actually smaller today.?

C.The world is changing its size.?

D. The distance between England and America has changed since the War of 1812 ?

34. Two hundred years ago,news between the continents was carried____.?

A.by telephone and telegraph B.by land?

C.by air D.by sea ?

35. The New Orleans Battle could have been avoided if the peace agreement had been signed____.?

A.by both sides B.in time?

C.in America D.in England ? 答案
