阅读下面短文,掌握其大意,然后从各题所给的A,B,C,D四个选项中选出最佳选项。

    A thousand years ago, Hong Kong was covered by a thick forest. As more and more people came to 1 in Hong Kong, these trees were cut down and burnt. Now there is 2 forest left, though there are still some small areas covered with trees. We call these woods, not forests.

    Elephants,tigers and many 3 animals were living in the thick forest. When people came to live in Hong Kong, the 4 began to die out. Early farmers grew rice and kept pigs and chickens in the valleys (山谷). They cut down the trees and burnt them. They needed fire to keep themselves 5 in winter, to cook their food and to keep away the dangerous animals. Elephants 6 disappeared because there was not enough food for them. So did most of the wolves and tigers. Monkeys and many other animals soon died 7 the same way.

    You might think that there are no longer any animals in Hong Kong except in the zoos. There  8 still about 36 different animals living there. One of the most interesting of Hong Kong's animals is the barking deer (麂). These are beautiful little animals with a rich brown coat and a white patch(补丁) under the tail. They look like deer but they are much smaller. They are less than two feet  9 . They make a noise rather like a dog barking. In Hong Kong the barking deer has only one real enemy – 10 . People hunt these little animals though it is illegal (违法的). There are now not many barking deer left. So it is important for people to protect wild animals.

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两项为多余选项。    

Faces, like fingerprints, are unique. Did you ever wonder how it is possible for us to recognize people?           Yet a very young child – or even an animal, such as a pigeon, can learn to recognize faces. We all take this for granted.

____ When we talk about someone’s personality, we mean the ways in which he or she acts, speaks, thinks and feels that make that individual different from others.

Like the human face, human personality is very complex. But describing someone’s personality in words is somewhat easier than describing his face. ____ ____ But if you were asked to describe a “nice person”, you might begin to think about someone who was kind, considerate, friendly, warm, and so forth.

There are many words to describe how a person thinks, feels and acts. Gordon Airport, an American psychologist, found nearly 18,000 English words characterizing differences in people’s behavior. ____ Bookworms, conservatives, military types – people are described with such terms.

People have always tried to “type” each other. Actors in early Greek drama wore masks to show the audience whether they played the villain’s or the hero’s role. In fact, the words “person” and “personality” come from the Latin persona, meaning “mask”. Today, most television and movie actors do not wear masks. ____

A  If you were asked to describe what a “nice face” look like, you probably would have a difficult time doing so.

B  But we can easily tell the “good guys” from the “bad guys” because the two types differ in appearance as well as in actions.

C  We also tell people apart by how they behave.

D  People have difficulty in describing the features of fingerprints.

E  And many of us use this information as a basis for describing, or typing one`s personality.

F  Experts say that actors differ in their behavioral and physical characteristics in acting.

G  Even a skilled writer probably could not describe all the features that make one face different from another.
