W: How is it that Bill could've gained so much muscle in a single year?M: Well, it's hard to say—but I suspect it was more than just exercise that helped him. I figure he's taking drugs.Q: What does the man suspect?12. W: How has your life changed since you started exercising every day after work?M: Too many ways to count! But the biggest surprise was how others look at me. People respect me more now that I'm healthy.Q: What was the biggest surprise for the man?13.13. W: I'd eat better and exercise more, but these things are too expensive for me.M: That's just an excuse! Healthy living doesn't need to cost much at all. You could run outside and eat more vegetables.Q: What does the man think?14. W: There are all sorts of news reports about a new pill that is supposed to help people lose unnecessary fat.M: Ah, I never believe these things. There's no replacement for exercise.Q: What is the conversation about?15. W: I've heard that 30% of people in our country are overweight and this makes them 60-70% more likely of an early death.M: Yeah. The worst news is that 50% of all children are too fat these days.Q: What percentage of children are overweight?16. W: I was afraid of talking to you about your health. But I think it's become a problem.M: You and Dad should leave me alone! Why don't you bother my sister? I'm not your only fat child, you know!Q: What is the relationship between the two speakers?W: You look so tired. What's the problem these days? Have you been ill?M: I'm not exactly sure what's been causing my problems. But I think it has something to do with me discontinuing my exercise program last month.Q: According to the man, what might be causing his problems?18. W: I was able to lose a lot of weight by eating better, but I'm still weak and soft.M: You look all right to me. But you could probably benefit from lifting the weights in the gym. Or better, take up swimming.Q: According to the man, what is the best thing for the woman to do?Long conversationsNo. 1M: Apples, tomatoes, pears... What do all these foods have in common? Water, that's what. They all contain lots of water, and that makes them the perfect weight-loss food.W: That's right. If you eat water-rich, lower-fat foods you can lose weight easily. You can start with a bowl of soup, have a salad, and then you can have a sandwich. Then you can bulk it up with lots of vegetables, and you can even have calories left for a fruit salad. This is a lot of food, but not many calories.M: Six hundred calories.W: Six hundred calories, yes.M: OK. Let's go back over it. Water-dense foods will fill you up and satisfy your hunger. That's a good thing when you're dieting, plus they're low in calories. But keep in mind, you can drink a glass of water and get the same effect. Fooling your body in this way is a little trick that can help you lose weight.W: Uh-huh. Fewer calories, but these foods won't leave you feeling hungry. Still, let's face it, water-dense foods just aren't as convenient as snack foods, and often they're a lot more expensive.Questions 1 to 5 are based on the conversation you have just heard.1. What is this passage about?2. What makes apples the perfect diet food?3. What can you begin your low-calorie meal with?4. What does the man call "a little trick"?5. What problem does the woman have with water-rich foods?No. 2M: Hey! Is Dad home?W: No. What's up?M: I have a problem.W: And you want to talk to him? What's wrong with talking to me? You used to do it all the time when you were younger.M: OK, OK. Have you heard the song All You Need is Love?W: Sure. I used to sing it to you when you were a baby. That's a famous song.M: Yeah—but it's a total lie, or it only tells half the story.W: OK, smart guy, then what's the full story?M: Love is important, but it's almost impossible to get if you are as fat as me.W: Hey, why are you feeling sorry for yourself? You've got a girlfriend.M: Who, me?W: I thought you had a girlfriend.M: Never. Women won't go anywhere near me because I'm too fat.W: Maybe you should start exercising to bring down your weight. Then maybe you could find the love you need.M: Yeah, of course you're right. But I find it so hard to get started on a program.W: Well, when it's important enough for you to work for, you'll start exercising. I, for one, have always exercised every day. And I never had a problem with love.Questions 1 to 5 are based on the conversation you have just heard.1. What is the relationship between the two speakers?2. What did the man use to do when he was younger?3. Why does the man have trouble finding a girlfriend?4. What has the woman never had trouble with?5. What is this conversation about?PassagesNo. 1Experts say moods are feelings that tend to become fixed, influencing a person for hours, days or even weeks. That's great if your mood is a pleasant one, but a problem if you are sad, anxious, angry or simply lonely.Perhaps the best way to deal with such moods is to talk them out; sometimes, though, there is no one to listen. Modern doctors offer a lot of anti-anxiety drugs. What many people don't realize, however, is scientists have discovered the effectiveness of several non-drug approaches to shake you free from an unwanted mood. These can be just as useful as drugs.Exercise seems to be the most efficient cure for a bad mood. "If you could always exercise, you'd be in high spirits," says one health expert.Researchers have explained why exercise is a better mood-raiser than drugs. Physical labor such as housework, however, does little. The key is exercise—running, cycling, walking, swimming or other such activities—boosts the heart rate, increases blood flow and improvesthe body's use of oxygen. Exercise for at least 20 minutes each time, three to five times a week.Questions 1 to 5 are based on the passage you have just heard.1. What is the main subject of the passage?2. What is perhaps the best way to deal with a bad mood?3. What is the speaker's attitude towards drugs in dealing with bad moods?4. Which is useful to cure bad moods?5. How often should a person exercise?No. 2There are several reasons for the new popularity of bicycles. The cost of fuel for cars is one reason. Another is the need to keep the environment clean. The third reason is a desire for exercise. Americans are one group of people who are leaving their cars at home. In fact, there are more than 100 million bicycles in the United States alone.The bicycle is more convenient and saves more energy than the car. Furthermore, it is nearly as fast as the automobile for short city trips. Many people, however, are still using their cars. Why? Time is one reason. It is still faster to drive a car than to ride a bicycle, especially for long trips.Another reason why people do not ride bikes is their lack of confidence. Some new bicycle riders, around 18 percent, do not trust themselves. If they are not completely certain that they can ride well enough, they decide to take their cars.A more important reason is lack of knowledge about bicycles. For example, the average person does not know how to shift the gears of the ten-speed bicycle. Researchers say that 80 percent of the ten-speed bikes in the United States have never been shifted!Questions 1 to 5 are based on the passage you have just heard.1. Which of the following is one of the reasons for the new popularity of bicycles?2. Why do many people still use their cars instead of bicycles?3. What do people need to do if they want to make better use of bicycles?4. What percentage of the ten-speed bicycles have never been shifted in the United States?5. What is the passage mainly about?。
