London—Sheep, like turkeys and ostriches, are not considered the most clever animals. British scientists said last Wednesday humans may have underestimated the woolly creature. They could be much smarter than we think.

Researchers at the Babraham Institute in Cambridge, southern England, have shown that the 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 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, they have to have reasonable intelligence; otherwise, what is the point of having a system for remembering faces and not 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 (unable to speak, unintelligent) animals because they live in large groups and do not appear to have much individuality 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 which look extremely similar.

“The most important finding (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 individuals for a very long time,” said Kendrick. “It is a very strange system. They are showing similar abilities in many ways to humans.”

Sitting on the peaceful coast of Galapagos Islands. Ecuador, watching the sun move quietly into the sea, you shouldn't forget that Charles Darwin (1809-1882) arrived here in 1835. He stayed on the islands for five weeks, observing various animals. This finally inspired his famous work, On the Origin of Species. You can certainly follow Darwin's footsteps and enjoy a trip from four to seven days to the islands.

The islands are certainly a paradise (天堂) for wildlife, as there are no natural killers on the islands and the number of boats and visitors is under government control. Though you cannot walk freely as Darwin did about 200 years ago, each day is as impressive as it could be.

The most well-known animal of the Galapagos is the giant tortoise (巨型海龟), which can be seen moving slowly around the highlands of Santa Cruz, the second largest island in the archipelago (群岛). Some of these creatures are so old that they might have been seen in their youth by Darwin himself.

Despite strict control over activities and timing, your stay on the Galapagos will be remembered as a chain of incomparable pictures: diving with sea lions that swim and play within inches of you; feeling small sharks touch your feet as you swim; and, most magically, seeing a whale and her baby surface with a great breath of air.

Travelling between the islands and observing the wildlife that so inspired Darwin, you will feel as though you are getting a special view of an untouched world. At night you will sleep on board the ship, leaving the wildlife in complete occupation of the islands, which are as undisturbed now as they have been since the beginning of time.

1.What do we know about Darwin's visit to the islands?

A. He completed his famous book on the islands

B. He was touched by the geography of the islands

C. He studied different creatures on the islands

D. He was attracted by well-known animals of the islands

2.Which of the following plays a role in making the islands "a paradise for wildlife"?

A. People cannot visit the islands as they wish.

B. Animals on the islands feed on grass.

C. Local government forbids killing wildlife.

D. Tourists are not allowed to touch the animals.

3.Your stay on the islands will be most impressive mainly because of _____.

A. Darwin's inspiring trip

B. The beautiful sea views

C. a closer view of animals

D. various daring activities

4.Which of the following would be the best title for the passage?

A. Galapagos as a Paradise for Adventures

B. Charles Darwin as a Symbol of Galapagos

C. A successful Example of Wildlife Protection

D. A Unique Attraction for Wildlife Lovers
