听力原文： The year is 2501, and the Earth is desperately short of fuel. All Earth's coal, oil and wood have been used up long ago, and scientists have been sent to the ends of the universe in search of alternative forms of energy.

A rich and powerful civilization has been discovered on the planet Jupiter, and Earth is supplied with fuel by constant supply fleets from that planet, but the price is very high. Unless it discovers an alternative source of energy soon, civilization on Earth will fail, and its inhabitants will have to move to other planets where they will be little more than slaves. Then Jupiter will take possession of Earth-- the most beautiful, most desirable planet in the universe.

Human scientists have been sure for a long time that Jupiter possesses a method of creating constant energy and now ten explorers on a secret mission from Earth have discovered the secret--a kind of heavy, green dust which will change salt water to high grade petroleum. This dust covers a large part of Jupiter's surface, and just a few pounds of it could solve the world's energy crisis since it would reproduce itself continuously in Earth's atmosphere.

A．Explorers.

B．Doctors.

D．Coal-miners.

听力原文：W: Good morningM: Good morning.W: Well, what are your predictions about the world

听力原文：W: Good morning

M: Good morning.

W: Well, what are your predictions about the world？ What is it going to be like in the year 2020？

M: Hum, if present trends continue, I'm afraid the world in 2020 will be more crowded and more polluted than the world we live in now.

W: Don't you think we will be able to cope with the increase in world population？

M: I don't think so. Even though production is constantly increasing, the people of the world will be poorer than they are today. For hundreds of millions of the desperately poor, the supply of food and other necessities of life will not be any better. And for many they will be worse, unless the nations of the world do something to change the current trends.

W: What is your estimate of world population in the year 2020？

M: If present trends continue, that is with the number of births by far exceeding the number of deaths. In 2020 the world population could approach 6,500 million people.

W: How many people are born every day？

M: About 250 every minute, but only 100 people die!

W: That's worrying! Will there be enough oil to satisfy our needs in the year 2020？

M: During the 2000s, world oil production will reach the maximum and the price of oil will begin to increase. At the next ten years of the century, the available supplies will not be sufficient for our needs. So, at lest part of these needs will have to be met by alternative sources of energy.

W: Well, that's a warning that we all need to take seriously. And with that warning, we end part one of this week's.

(23)

A．Increase food production.

B．Increase oil production.

C．Birth control.

D．All of above.

听力原文：Scientists have observed that plants themselves produce many poisonous chemicals

听力原文： Scientists have observed that plants themselves produce many poisonous chemicals for defense against insects. But insects have developed ways of dealing with them and,in fact,have been eating plants for about 250 million years.Now insects are using these same mechanisms to deal with man-made poisons-insecticide.This is why resistance of insects to insecticide has developed so rapidly.What should be done？Scientists studyilg the problem suggest that farmers use less insecticide.At the moment,famlers regularly spray crops as a precaution against problems that are caused by large numbers of pests.They should,instead,spray only where pests have actually been seen.Secondly,farmers could use a combination of two or three jnsecticide at once.To survive,the insects would need to become resistant to two or more poisons at the same time.The most surprising suggestion,perhaps,perhaps,is that,at certain times of the year,famers should actually try to attract new insects onto the crops they are trying to protect.The new insects will mate with those which survived from a certain kind of insecticide and will lessen the latter's resistance to it.

Scientists hope that these and other measures will postpone the day when farmers and scientists will have to stand by while new super bugs which may be resistant to all our poisons invade our farms and devour our crops.

A．There are 250 million plants eaten by insects.

B．There are fewer plants than 250 million years ago.

C．They have their way of guarding against insects.

听力原文：Are electric cars the way of the future？Automobile manufactures are under pressur

听力原文： Are electric cars the way of the future？Automobile manufactures are under pressure to develop cars that do not pollute.One powerful motive is a California law requiring that by the year 2020 ten percent of new car sells in the state be so called zero-emission vehicles.These cars must put no pollutants whatsoever into the at-mosphere.

California is a huge market for the automobile companies,so they are working hard to meet these standards. So far the electric car seems to be the best alternative.So the big advantage of electric cars is that they don't pollute.However they will be in competition with gas-powered cars and that's where the weaknesses come out.The big problem is that the batteries that power electric cars weigh a lot relative to the amount of power they deliver.For instance,in one prototype electric car,the batteries weighed 400 kilograms.And they provide enough energy to go 250 kilometers before recharging,which takes eight hours.Compare that to a moderately fuel-efficient conventional car,it can go 600 to 700 kilometers on a tank of gas and refilling takes just minutes.If there are other drains on an electric car's batteries besides the motor,headlights,air-conditioning or a heater,its already limited range will be significantly reduced.So automobile engineers are trying to make more powerful batteries that would increase the cars'range and make them more attractive to buyers.

Why does the electric car seem to be the best alternative so far？

A．It is comfortable.

B．It is best made.

C．It causes no pollution.

D．It makes less noise.

听力原文： Why, you may wonder, should spiders be our friends？（26)Because they destroy so

听力原文： Why, you may wonder, should spiders be our friends？ (26)Because they destroy so many insects, and insects include some of the greatest enemies of the human race. Insects would make it impossible for us to live in the world; they would devour all our crops and kill our flocks and herds, if it were not for the protection we get from insect-eating animals. (27)We owe a lot to the birds and beasts which eat insects but all of them put together kill only a fraction of the number destroyed by spiders. Moreover, unlike some of the other insect eaters, (26)spiders never do the harm to us or our belongings.

Spiders are not insects, as many people think, nor even nearly related to them. One can tell the difference almost at a glance, (28)for a spider always has eight legs and insect never more than six.

How many spiders are engaged in this work in our behalf？ One authority on spiders made a census of the spiders in grass field in the south of England, and he estimated that there were more than 2 250 000 in one acre; that is something like 6 000 000 spiders of different kinds on a football pitcll. (29)Spiders are busy for at least half the year in killing insects. It is impossible to make more than the wildest guess at how many they kill, but they are hungry creatures, not content with only three meals a day. It has been estimated that the weight of all the insects destroyed by spiders in Britain in one year would be greater than the total weight of all the human beings in the country.

(33)

A．Because they are beneficial insects.

B．Because they destroy insects without hurting us in any way.

C．Because they protect insect-eating animals.

D．Because they include some of the greatest enemies of the human race.
