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 and 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.

Have you ever done something foolish and it made you feel so embarrassed（尴尬的）?
Well, that’s exactly how I felt. On a Saturday morning last autumn．I went to town to do some shopping and as I was on my way home from the shop，it suddenly began to rain. I at once ran into a nearby phone box because I didn’t have an umbrella．It was raining so heavily that I had to stay in the phone box until it stopped．
A few moments later，I saw a young man walk up to the phone box，wearing a yellow raincoat and holding a box. I didn’t want to go out into the rain，so I picked up the phone and pretended（假装） I was talking to someone. I thought the man would go away，but he didn’t. He just waited in the pouring rain，and I acted as if I was deep in conversation.
Luckily，the rain stopped after about ten minutes．“Okay，Mum，” I said loudly into the phone，“I’ll see you later. Bye!” I put the phone down, picked up my shopping bag and walked out of the phone box. “I’m sorry I took so long.” I said to the man．
“Oh, I don’t want to use the phone,” he answered, smiling．“I’ve just come to repair it. There is something wrong with it, you see .” I felt myself go red in the face and I hurried away with my head down，feeling a complete fool. That was certainly one of the most embarrassing moments of my life!

Waste can be seen everywhere in the school. Some ask for more food than they can eat , some students don’t to turn off the water taps after they finish washing, and others often forget to turn off the when they leave the classroom. They say these things are cheap, I don’t agree with them.
Waste can bring a lot of problems. Though China is rich in some resources (资源), we are of others. It is reported that we will have no coal or oil to in 100 years. So if we go on wasting our resources, can we use in the future and where can we move? Think about it. I think we say no to the students who waste things every day. should stop wasting as soon as possible. If we do our best, waste can be stopped and many natural resources can be saved.
