In today’s world, almost everyone knows that air pollution and water pollution are harmful to people’s health. However, not all know that noise is also a kind of pollution, and that is harmful to human, too.
People who work and live under noisy conditions usually become deaf(耳聋的). Today, however, scientists believe that 10% of workers in Britain are deafened by the noise where they work. Many of the workers who print newspapers and books, and who weave 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 people, 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 plane 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（分贝） can cause deafness.
Nowadays the governments in many countries have made laws to reduce or control noise and make it less than 85 decibels. In China, the people’s government is trying to solve not only air and water pollution problems but also the noise pollution problems.

When I was young, my father used to grow carnations — a kind of flower that was red, pink or white. He took care of them with much love and devotion. Every day he came home from work, he would enjoy watching them. And he used to tell us, “No one should touch my flowers.”
One day, my younger sister Clemence, who loved dad very much, wanted to help him. So she cut the carnation from their stems（枝干）one by one and arranged them on the ground. She believed that dad would be very pleased to see them that way.
When mom and I realized what my sister had done, we became completely speechless. However, my sister had no idea why no one showed her any appreciation. When dad arrived, he went as usual straight to watch the flowers. Seeing his flowers lying on the ground like dead animals, he was shocked at first. He looked towards the street to see if it was any of the neighbors’ children who could have done it. Then he looked at mom in silence. Finally mom, who always taught us to tell the truth no matter what, said, “No bad neighbors did this great job, only your lovely daughter Clemence.”
