In today's world, almost everyone knows that air pollution and water pollution are harmful to people's health. However, not all the persons know that noise is also a kind of pollution, and that is harmful to human health, too.

People who work and live under noisy conditions usually become deaf（聾）. Today, however, scientists believe that 10 percent of workers in Britain are being deafened by the noise where they work. Many of the workers who print newspapers and books, and who weave（織）cloth become deaf. Quite a few people living near airports also become deaf. Recently it was discovered that many teenagers in America could hear no better than 65-year-old persons, for these young people like to listen to pop music and most of pop music is a kind of noise. Besides, noise produced by jet planes or machines will make people's life difficult and unpleasant, or even make people ill or even drive them mad.

It is said that a continuous noise of over 85 decibels（分貝）can make people deaf. Now the governments in many countries have made laws to control noise and make it less than 85 decibels.

When I was about 12, I had an enemy, a girl who liked to point out my shortcomings(缺點(diǎn)). Week by week her list grew: I was very thin, I wasn’t a good student, I talked too much, I was too proud, and so on. I tried to bear all this as long as I could. At last, I became very angry. I ran to my father with tears in my eyes.

He listened to me quietly, then he asked. “Are the things she says true or not? Janet, didn’t you ever wonder what you’re really like ? Well, you now have that girl’s opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said.”

I did as he told me. To my great surprise, I discovered that about half the things were true. Some of them I couldn’t change (like being very thin), but a good number I could—and suddenly I wanted to change. For the first time I go to fairly clear picture of myself.

I brought the list back to Daddy. He refused to take it.“That’s just for you,” he said.“You know better than anyone else the truth about yourself. But you have to learn to listen, not just close your ears in anger and feeling hurt. When something said about you is true, you’ll find it will be of help to you. Our world is full of people who think they know your duty. Don’t shut your ears. Listen to them all, but hear the truth and do what you know is the right thing to do.”

Daddy’s advice has returned to me at many important moments. In my life, I’ve never had a better piece of advice.

1.What did the father do after he had heard his daughter’s complaint?

A. He told her not to pay any attention to what her“enemy” had said.

B. He criticized (批評) her and told her to overcome her shortcomings.

C. He told her to write down all that her“enemy” had said about her and pay attention only to

the things that were true.

D. He refused to take the list and have a look at it.

2.What does “Week by week her list grew” mean?

A. Week by week she discovered more shortcomings of mine and pointed them out to me.

B. She had made a list of my shortcomings and she kept on adding new ones to it so that it was growing longer and longer.

C. I was having more and more shortcomings as time went on.

D. Week by week, my shortcomings grew more serious.

3.Why did her father listen to her quietly?

A. Because he believed that what her daughter’s “enemy” said was mostly true.

B. Because he had been so angry with his daughter’s shortcomings that he wanted to show this by keeping silent for a while.

C. Because he knew that his daughter would not listen to him at that moment.

D. Because he wasn’t quite sure which girl was telling the truth.

4.Which do you think would be the best title for this passage?

A. Not an Enemy, but the Best Friend

B. The Best Advice I’ve Ever Had

C. My Father

D. My Childhood
