　 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(拖拉机), 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(不断的) loud noise can cause a loss of hearing.

Scientists use a unit of measure called decibel(分贝) 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(层次) 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.

No-car day. On a no-car day, nobody comes to school in a car-not the students and not the teachers! Cars give pollution to our air, so remember:

Walk, jump, bike or run.

Use your legs! It’s lots of fun!

No-garbage(垃圾) lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will choose the classes that make the least garbage and report them to the whole school!

We love our environment. Let’s work together to make it clean!
