听力原文： When you take a walk in any of the cities in the West, you often see a lot of people walking dogs. It is still true that a dog is the most useful and faithful animal in the world, but the reasons why people keep a dog have changed. In the old days people used to train dogs to protect themselves against attacks by other beasts. And later they came to realize that a dog was not only useful for protection but willing to obey his master. For example, when people used dogs for hunting, the dogs would not eat what was caught without permission. But now people in the city need not protect themselves against attacks of animals. Why do they keep dogs, then？ Some people keep dogs to protect themselves from robbery. But the most important reason is for companionship. For a child, a dog is his best friend when he has no friends to play with. For young couples, a dog is their child when they have no children. For old couples, a dog is also their child when their real children have grown up. So the main reason why people keep dogs has changed from protection to friendship.

A．For protection against other animals.
B．For protection against other dogs.
C．Just for fun.
D．For the purpose of guarding the house.

M: Actually, Laura, I think we laugh because we are glad it didn't happen to us. But of course there is also a kind of humorous satisfaction in seeing somebody self-important making a fool of themselves.
W: Yes, and then there are a lot of jokes about people who are too fat or physically handicapped, you know, deaf, or short-sighted, things like that. After all, it's not really funny to be like that.
M: Oh, I think that's because we're embarrassed. We don't know how to cope with the situation. Perhaps we are even a bit frightened we might get like that, so we laugh. What about the custard pie routine？
W: What do you mean "custard pie routine"？
M: You know, all those old films where someone gets so outraged with his boss, he picks up a custard pie and plasters it all over the other person's face.
W: That never makes me laugh very much, because you can guess it's going to happen. But a lot of people still find it laughable. It must be because it's the sort of the thing we'd all love to do once in a while and never quite have the courage to.
M: I had an old aunt who used to throw cups of tea at people when she was particularly irritated. She said it relieved her feelings.
W: It must have come a bit expensive.
M: Not really. She took care never to throw her best china.

Perhaps the most startling theory to come out of kinesics, the study of body movement, was suggested by Professor Birdwhistell.He believes that physical appearance is often culturally programmed.In other words, we learn our books, but we are not born with them.A baby has generally unformed facial features.A baby, according to Birdwhistell, learns where to set the eyebrows by looking at those around family and friends.This helps explain why the people of some regions of the United States look so much alike.New Englanders or Southerners have certain common facial characteristics that cannot be explained by genetics.The exact shape of the mouth is not set at birth;it is learned after.In fact, the final mouth shape is not formed until well after permanent teeth are set.For many, this can be well in adolescence.A husband and wife together for a long time often come to look somewhat alike.We learn our looks from those around us.This is perhaps why in a single country there are areas where people smile more than those in other areas.In the United States, for example, the South is the part of the country where the people smile more frequently.In New England they smile less, and in the western part of New York state still less.Many Southerners find cities such as New York cold and unfriendly, partly because people on Madison Avenue smile less than people on Peachtree Street in Atlanta, Georgia.People in densely populated urban areas also tend to smile and greet each other in public less than do people in rural areas and small towns.()
A.Ray Birdwhistell can tell what region of the United States a person is form. by how much he or she smiles
B.Ray Birdwhistell is a leader in the field of kinesics
C.Ray Birdwhistell says that our physical appearance is influenced by the appearance of people around us
D.People who live in the country are more friendly than people who live in densely populated areas
