Sheep, like turkeys and ostriches, are not considered the cleverest animals. British scientists said last Wednesday human may have underestimated(低估) the woolly creatures. They could be much smarter than we think.

Researchers at the Babraham Institute in Cambridge, southern. England, have shown that animals have a good memory system and are extremely good at recognizing faces--which they think is a sure sign of intelligence.

Behavioral scientist Keith Kendrick and his friends trained 20 sheep to recognize and distinguish(区别) 25 pairs of sheep faces and used electrodes(电极) to measure their brain activity, which showed they could remember 50 faces for up to two years.

"If they can do that with faces, the fact is that they have to have reasonable intelligence, otherwise, what is the point of having a system for remembering anything else," Kendrick said in an interview.

So hours of seemingly mindless eating grass may not be so mindless after all.

Kendrick believes sheep got their reputation as dumb animals because they live in large groups and do not appear to have much ind

ividuality and are frightened of just about everything.

All animals, including humans, once they are frightened don't tend to show signs of intelligent action," he explained.

In research reported in the science journal Nature, Kendrick and his team showed that sheep, like humans, have a specialized system in the brain, which allows them to distinguish between many different faces that look extremely similar.

"The most important findings of the study is that they are able, both from a behavioral point of view and from looking at the way the brain is organized, to remember a large number of faces of individuals for a very long time," said Kendrick. "It is a very strange system. They are showing similar abilities in many ways to humans. "

From the first paragraph we can find that ______.

A. people used to think sheep are smarter than the other animals

B. people used to raise sheep in a wrong way

C. people don't consider sheep as clever animals

D. people have done a lot of research on sheep

From what Kendrick said in the interview we learn that ________.

A. scientists have learned a lot about sheep's intelligence

B. scientists have learned little about sheep's intelligence

C. scientists can't do anything more about sheep's memory

D. scientists don't have to research animals' memory

As is shown in the passage _________.

A. sheep are among the weak animals

B. it is not right for people to raise sheep in groups

C. when sheep eat grass in the fields their minds may be active

D. if people feel frightened, they may become more brave

When scientists found that sheep show similar abilities in many ways to humans they may think it _____.

A. worrying B. moving C. frightening D. interesting

Of the 10,000 or so species of birds, 46 cannot 37 . Flight plays a key role in 38 for most birds. It allows them to find food over a 39 area and to get away from enemies. Ancestors of flightless birds may have 40 their ability to fly because they had no regular predators (捕食者) or did not need to fly to find food. Rather than fly, some of these birds developed other 41 to catch food and avoid enemies. Two examples of 42 birds are penguins and ostriches.

43 birds that fly, penguins do not have wide wings or large feathers. In order to catch the fish they feed on, penguins use their powerful wings to swim 44 . And when they swim, they look as if they are flying through the water. The 45 of penguins’ bodies makes it possible for them to dive deep underwater, 46 their thick feathers protect them from the cold.

Ostriches are known for their long legs, long necks, and large size. To 47 themselves, they stay in groups and use their excellent sight and hearing to 48 enemies. As soon as 49 approaches, they can run at a speed of more than 65 kilometers per hour to 50 . In addition to using their strong legs to run, they can kick powerfully.

Not all flightless birds have been 51 in protecting themselves. Flightless birds on some islands had no enemies until people 52 .

第三部分阅读理解 (共20小题；每小题2分，满分40分)

阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。

Birds are the only animals with feathers, although some other animals, such as insects and bats, also have wings. Nearly all birds can fly, and even flightless birds, such as ostriches (鸵鸟), penguins, evolved from flying ancestors.

Birds are found worldwide in many habitats. They can fly over some of the highest mountains on earth as well as both of the earth’s poles, dive through water to depths of more than 250m, and occupy habitats with the most extreme climates on the planet, including arctic tundra (冻土地带) and the Sahara Desert. Certain kinds of seabirds are commonly seen over the open ocean thousands of kilometers from the nearest land, but all birds must come ashore to raise their young.

Highly developed animals, birds are sensitive and responsive, colorful and graceful, with habits that excite interest and inquiry. People have long been fascinated by birds, in part because birds are found in the same habitats in which humans live. And like people, most species of birds are active during daylight hours. Humans find inspiration in birds’ capacity for flight and in their musical calls. Humans also find birds useful---their flesh and eggs for food, their feathers for warmth, and their companionship. Perhaps a key basis for our friendliness with birds is the similarity of our sensory worlds: Both birds and humans rely more heavily on hearing and color vision than on smell. Birds are useful indicators of the quality of the environment, because the health of bird populations mirrors the health of our environment. The rapid decline in birds populations and the accelerating extinction rates of birds in the world’s forests, grassland, wetlands, and islands are therefore reasons for great concern.

1.Which of the following would be the best title of the text?

A. Animals with Feathers and Wings

B. Our friendliness with birds

C. An introduction to Birds

D. Bird’s life

2 What does the second paragraph mainly tell us ?

A. Bird’s friendship B. Bird’s habitats

C. Bird’s raising D. Bird’s environment

3.Which of following is NOT true according to the passage ?

A. Bird’s flying abilities and musical calls inspire humans greatly.

B. Birds live in the same surroundings in which humans live.

C. Both birds and humans rely more heavily on hearing and smell than on color vision.

D. Bird’s flesh and eggs for food, bird’s feathers for warmth, and their companionship are useful to us.

4.From the text it may imply but NOT state that __________.

A. the environment is being damaged seriously

B. if you want to raise birds, you should pay attention to environment

C. the environment affects the human beings

D. bird populations decrease rapidly
