Reading Comprehension (20%)Section A (1%×10=10%)Answer briefly the questions after each passage. Write the answers on the Answer Sheet.Passage 1Many people seem to know little about physical fitness. Even those who have been exercising for years have wrong ideas about how exercise and their bodies work. Here is one of the most common misconceptions: I’ve been doing 100 sit-ups and side bends a day for weeks. Why can’t I get rid of my fat waist?Because spot reduction is almost impossible. ”When you use fat, it comes from fatty substances throughout the body, not from one specific part,” says Robert M Otto, director of the Human Performance Laboratory at Adolphi University. Sit-ups are fine for strengthening the abdominal muscles, but they won’t melt fat away.So how do you lose fat? It seems relatively simple: just burn off more calories through exercise than you take in through food. Even then the weight problem may be the last to go: There’s a genetic tendency to lay down fat in certain a reas. We lose weight last from the place we put it on first. For most men, that will be in the abdominal or side areas, and for most women the upper thighs, buttocks and arms.1. What is the purpose of the writer in writing this passage?To correct _____________.2. Where does fat come from when you use it?From _____________.3. Sit-ups cannot melt fat away, but they can _____________.4. Where do men lose weight last?In the _____________.5. Why do men and women put on weight in different parts of the body?There is a _____________.Passage 2On the basis of research that we’ve been doing for the past six years, 40 percent of all Americans, or more than 80 million people, consider themselves shy. Among the notables who have at s ome time in their lives so described themselves are President and Mrs. Carter, England’s Prince Charles, movie star Catherine Deneuve, and TV’s Carol Burnett and Barbara Walters. Many people who publicly do not appear shy nevertheless experience the pain of shyness.Shyness develops out of the particular experiences we have in the home or in school. Our research shows that a quarter of the people who are shy as adults were not shy as children. Shyness makes it difficult to meet new people, and to make friends. It prevents an individual from speaking up, expressing opinions and values. With authorities such as a boss or a teacher, the shy are less likely to communicate effectively or express criticism.Can shy people change their behavior? Sometimes they can force themselves to do things that are difficult. Practice makes perfect.People who have more self-confidence can notice when people are shy and encourage them to talk and praise them when they are successful in their job or studies. Shy people feel miserable much of the time. Others can help them feel more comfortable.6. How many people consider themselves shy?7. How does shyness develop?8. How does shyness make life difficult?9. What does ”practice makes perfect” mean in the third paragraph?10. How can we help shy people?Section B (2% ×5 = 10%)Read passages A to E and complete the statements or answer the questions below. Write the answers on the Answer Sheet.1. Read Passage A.
