Ⅲ.阅读理解(每小题2分，共40分)

阅读下面的短文，从每题所给的四个选项(A、B、C、D)中，选出最佳选项。

A

1970 was“World Conservation Year”. The Moduleed Nations wanted everyone to know that the world is in danger. They hoped that government would act quickly in order to conserve nature. Here is one example of the problem. At one time there were, 1,300 different plants, trees and flowers in Holland, but now only 860 remain. The others have been destroyed by modern man and his technology. We are changing the earth, the air and water, and everything that grows and lives. We can't live without these things. If we continue like this, we shall destory ourselves.

What will happen in the future? Perhaps it is more important to ask，“What must we do now？” The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation is necessary. Many are helping to save our world. They plant trees in forests, build bridges across rivers, and so on. In a small town in the Moduleed States a large group of girls cleaned the banks of eleven kilometers of their river. Young people may hear about conservation through a record called NO ONE'S GOING TO CHANGE OUR WORLD. It was made by the Seattles, Cliff Richard and other singers. The money from it will help to conserve wild animals.

36．There are fewer plants, trees and flowers in Holland now because ________.

A．Holland does not need so many plants, trees or flowers

B．many plants, trees and flowers don't grow there any more

C．some of them are useless

D．they are polluted

37．We shall destroy ourselves if we don't________.

A．go on cutting the plants

B．build bridges across rivers

C．try our best to save the world

D．conserve wild animals

38．NO ONE'S GOING TO CHANGE OUR WORLD was________.

A．an important book published in 1970

B．a talk given by an official from the United Nations

C．a record calling on people to conserve nature

D．a film made to protect nature

39．What is the most important thing for us to do to save our world?

A．We should join the singers to collect money.

B．We should stop hunting wild animals.

C．We should know what would happen in the future.

D．We should know what we should do and begin to do it now.

B

Scientists have recently discovered that animals that live in groups, such as elephants, foxes, and wolves, are more likely to follow rules. If they don't, and each does its own thing, the group will probably break apart. Group members would be forced to live alone, and would have a harder time hunting and raising their young. That's probably why a traveling wolf pack was seen stopping and waiting for its limping (跛行的) leader to catch up. Similar social ties are believed to be responsible for a captive elephant saving her friend from drowing.

Sometimes, though, animals try their best to do what's right, even when there's nothing in it for them. Nobody knows exactly why. “It might simply feel good to be kind, just as it does for humans，” says Bekoff. If your friend wasn't nice to you, what would you do? Maybe you would just walk away. That's exactly what a wild red fox did when she was playing boxing with another fox.

Toby was a generous cat. For ten years, the kind kitty shared his food with a spaniel (长耳狗) named Katie. After supper, owner Linda Gustafson always divided up the table scraps. She'd drop some in Katie's bowl on the floor and some in Toby's dish on the kitchen counter. Gustafson kept the cat's dish up high to keep Katie from stealing Toby's treats. As it turned out, Katie didn't need to steal; she only had to beg. Every night, the spaniel ate her food in a few seconds. Then she's sit and stare at the cat and every night. Toby would be nice. Using his paw, he'd flick several pieces of tasty food down to the waiting pup. Apparetnly Katie appreciated it, because whenever she was curled up in her beanbag bed and the cat walked over, she would give up her nice, warm spot. “Toby would then lie down in center of the beanbag，” says Gustafson, “and Katie would lie on the floor.”

40．The reason why some animals prefer to live in groups lies in that ________.

A．they have to follow natural rules

B．they are afraid of staying alone

C．they cannot find food by themselves

D．living alone would make their lives harder

41．According to Bekoff, animals try their best to do what's right because ________.

A．it feels good to be kind

B．animals are friendly by nature

C．they have learned to do so for a long time

D．they want their owners to like them

42．It can be inferred from the last paragraph that ________.

A．Linda always lets the animals eat together

B．Katie sometimes gets her food by stealing

C．Toby is generous but Katie isn't

D．Katie and Toby help each other

C

Far from the land of Antarctica(南极洲), a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.

For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.

Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish's blood and measured its freezing point.

The fish were taken from seawater that had a temperature of －1.88℃and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to －2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixtu
