大学英语四级模拟题目3答案(2)

W: [24] But you don’t learn a language from the rules, anyway. You have to use it.

M: Yes. That’s something else they tell us. But why can’t we just go to class, study, and do our homework? That’s what I know how to do.

W: Look at this way, can you learn to play soccer by sitting at home and reading about soccer? M: No, of course. Not if you want to play well.

W: But why not? You could understand the rules of strategy, the duties of each position, and all the special situations. You have to feel the ball, practice kicking it hundreds of times, practice running down the field, moving toward the goal, and centering the ball. No one can learn that by passively studying. Learning a language is more like learning to play soccer than learning mathematics. You have to ask a lot of questions, and hear how the answers sound. You have to listen to how people indicate the important part of what they’re saying. And then of course endless practice on all the details—spelling, “s” endings, articles…just likes practice in simple dribbling and kicking.

M: But if it’s a skill like soccer, not a science, why do they teach it in schools and universities, and give you diplomas and grades?

W: That’s a good question. It is confusing, but languages are important and people do want to learn them. But the main thing is to practice the language a lot, just like soccer.

M: [25] Maybe I’ll join a soccer team and practice English and soccer at the same time. I can talk with people before and after the practice.

W: That’s a good idea.

Section B

Passage One

【听力原文】

[26] There are so many things going on in our modern lives, and change happens so quickly.

[27] It is hard to imagine a time when things were slower and you could really see a new thing come into your life and to remember the day or the year when those things happened. I know that today, for example, there are many instances of second and third generations of things, such as television or radios, when some of us were not even aware that there was a first generation.

A friend of mine was born at the end of the19th century, and talking to her, I really got a sense of her being a living history book, of being able to talk about the changes in her own life and to know that these changes were really the changes that society was going through.

She gets really excited, for example, when she talks about the first time she ever saw a camera, and even more excited when she saw herself in the picture that the photographer took. She lived in a small town, and at the time that she was very young, there were no cars or trains in her town at

all. As she grew up, cars and trains came in, and [28] she remembers her first ride with a real sense of amazement that anyone could move so fast.

Passage Two

The first step to stop drug abuse is to know why people start to use drugs. The reasons people abuse drugs are as different as people are from one to another. [29] But there seems to be

one common thread: people seem to take drugs to change the way they feel. They want to feel better or feel happy or to feel nothing. Sometimes, they want to forget or to remember. People often feel better about their lives when they are under the influence of drugs. But the effects don’t last long. Drugs don’t sol ve problems. They just postpone them. No matter how far drugs may take you, it’s always around trip. After a while, people who use drugs may feel worse about themselves, and then they may use more drugs. If someone you know is using or abusing drugs, you can help. [30] The most important part you can play is to be there. You can let your friends know that you care. You can listen and try to solve the problem behind your friend’s need to use drugs. Two people together can often solve a problem that seems too big for one person alone. [31] Studies of heavy abusers in the United States show that they felt unloved and unwanted. They didn’t have close friends to talk to. When you or your friends take the time to care for each other, you’re all helping to stop dru g abuse. After all, what is a friend for?

Passage Three

[35] One way that scientists learn about man is by studying animals, such as mice, rats, and monkeys. The scientists in a laboratory are experimenting on mice. [32] They are studying the relationship between diet and health. At this time, over one hundred experiments are going on in this laboratory.

In this experiment, the scientists are studying the relationship between the amount of food the mice eat and their health. The mice are in three groups. All these groups are receiving is different. [33(1)] The first group is eating one cup of food each day, the second group is eating two cups, and the third group of mice is eating three cups.

After three years, the healthiest group is [33(2)] the one that is only eating one cup of food each day. The mice in this group are thinner than normal mice. But they are more active. Most of the day, they are running, playing with one another, and using the equipment in their cages. Also, they are living longer. [34] Mice usually live for two years. Most of the mice in this group are still alive after three years.

The second group of mice is normal weight. They are healthy, too. They are active, but not as active as the thinner mice. But they are only living about two years, not the three years or more of the thinner mice.

The last group of mice is receiving more food than the other two groups. Most of the day, these mice are eating or sleeping. They’re not very active. These mice are living linger t han the scientists thought—about a year and a half, but they aren’t as healthy. They’re sick more often than the other two groups.
