The sense of sound is one of our most important means (方法，手段) of knowing what is going on around us. Sound has a wasted product, too, in the form of noise. Noise has been called unwanted sound. Noise is growing and it may get worse before it gets any better. Scientists, for several years, have been studying how noise affects people and animals. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is a threat that should be looked at carefully. There is a saying about it being noisy that you can’t hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don’t we may have headaches, other aches and pains, or even worse mental problems. Noise adds more tension (紧张) to a society that already faces enough stress. But noise is not a new problem. In ancient Rome, people complained so much about noise that the government stopped chariots (四轮马车) from moving through the streets at night. Ways of making less noise are now being tested. There are even laws controlling noise. We can’t return to the “good old days“ of peace and quiet. But we can reduce noise—if we shout loudly enough about it.Why are scientists surprised by the findings in their noise study? Because the world is becoming more and more noisy. Because they have learned that noise is also a kind of pollution. Because noise is an unwanted waste for human beings. Because people knew little about the danger of noise before.

But I am still more delighted when they go, and the house is ours again. I feel that I may be mistaken in these guests, and this may happen at times. They leave me more room in which to live properly. My mind, like my body, wears its old clothes again. I like to think about life in this world, and it is not easy to do this when talkative people are all over the place. With the guests about, I find myself a solid. I feel uneasy. Often I feel I have nothing meaningful to say. I try my best to think of something interesting and useful to devote them. But usually it seems that no one appreciate what I focus on. Many times I even got angry over what they said, which made them upset. Frankly speaking; I am not used to gathering together with friends chatting, although I’d like them to stay with me.
