Part BDirections: You will hear four dialogues or monologues. Before listening to each one
Part BDirections: You will hear four dialogues or monologues. Before listening to each one, you will have 5 seconds to read each of the questions which accompany it. While listening, answer each question by choosing A, B, C or D. After listening, you will have 10 seconds to check your answer to each question. You will hear each piece ONLY ONCE.听力原文: Are you afraid to raise your hand in class even when you know the answer? If you are, most people would say that you are shy. If you feel shy, you are not alone. Nine out of ten people are at least a little shy. But however shy you are, scientific evidence seems to show that it isn't your fault. You may have been born that way. How do psychologists measure shyness? One way is by observation. They keep detailed records of people's actions, like how often these people speak to others or how long it takes someone to say hello to a stranger. Another way to measure shyness is to ask people questions. The test only takes about 10 minutes. It asks questions like "Do you like going a lot?" and "Do you have many friends?" People must answer either yes or no. These questions can predict how people actually behave in social situations. Suppose the test tells you that someone is shy, chances are good that person will act shy. When scientists measure shyness, they are really comparing degrees of shyness. In other words, when researchers say people are shy, they really mean they are more shy than others.Why does the speaker say that it isn't a fault to be shy?A.Because many people don't know how to behave in social situations.B.Because one may have been born that way.C.Because most persons are shy.D.Because it's good to be shy.
