摘要: The writer wrote the passage to tell students to . A. join in clubs B. help teachers C. make less pollution D. clean schools C Stop. Listen! What do you hear? You may hear many different sounds. Some of those sounds may be noise. Noise is a loud or unwanted sound. Noise can be caused by many kinds of machines, such as motorcycles, jet planes, farm tractors, rock music is also noise. What happens to people who live near noisy machines or use them over a period of time? Doctors have found that these people have trouble in sleeping. But, most important, constant loud noise can cause a loss of hearing. Scientists use a unit of measure called decibel to measure the loudness of a sound. The sound of a quiet room, for example, measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from traffic and from some rock bands can measure over 120 decibels. Noise at this high level causes the great hearing loss.

In most parts of the world, many students help their school make less pollution. They join in “environment(环境) clubs”. In an environment club, people work together to make our environment clean. Here are the things students often do.

Turn off the water! Do you know that some toilets can waste(浪费) twenty to forty tons of water an hour? In a year, that would fill a small river! In environment clubs, students mend those broken toilets.
