六、阅读理解。
Do you think there is too much noise in the world? Perhaps you do. If you live near an airport, you will probably feel unhappy because of the noise of planes. It is said that the noise of planes or trains or lorries can make one deaf if he/she keeps on hearing it.
Noise is a kind of pollution. However, most people in our city do not seem to mind noise. They do not know it is harmful to their health. They like to enjoy music when they are doing their work. It is a new danger that music is played through powerful loudspeakers（扩音器）. It can reach 120 decibels（分贝）.
It is known that continuous（连续不断的） noise of over 85 decibels can make people deaf. For example, when newspapers and books are being printed, the noise is over 85 decibels, and some of the workers may become deaf. Scientists believe that ten per cent of all the workers in British printing offices have been deafened（使……聋） by the noise. Besides, noise of less than 85 decibels can make some people tired and nervous. We all know that too much noise makes things difficult and unpleasant. It can do great harm to health and prevent people from working well. Workers in noisy offices are not so efficient（高效的） as workers in quiet offices. Noise makes people less efficient. Can anything be done to keep down noise?
In China, the government has made several laws to keep down noise. We are trying to make airports and main roads quieter. In other countries, there are such laws too.
