Noise pollution is doing much harm to our hea...

Noise pollution is doing much harm to our health now. Noise，in fact，is unwanted sound and is a kind of invisible (无形的) killer. More and more students enjoy listening to music very much. When they listen to MP3 players, they like to turn up the volume (音量)．Some people love listening to loud music. Furthermore, while watching TV, they keep the volume up. But they haven't realized that the noise is weakening their hearing. In fact, the noise not only influences each member in the family, but also makes a difference to the comfort of neighbors.

Noise pollution is a source of increasing misery (痛苦) to people in our society. If people are often disturbed by it, they may feel uncomfortable or upset. What's worse, the noise can make people mad sometimes. If a worker works in a printing factory for too long, his/her hearing loss is much faster than a common person working in a quieter environment. So everybody must pay more attention to noise pollution. Generally speaking，the following four types of noise should be watched out for：

◆Noise in the street

◆Construction site (建筑工地) noise

◆Noise at work

◆Transportation noise

I think the local department (部门) should take measures to control the noise levels, but it's everybody's duty to keep a quiet environment.

1.Why is noise called a kind of invisible killer?

A. Because we can't see it with our own eyes.

B. Because it's really harmful to our health，but people don't realize it.

C. Because it often causes people to die.

D. Because it has no direct effect on humans.

2.What do the words “makes a difference to” mean?

A. influences　　 B. produces　　 C. refers　　 D. provides

3.Noise pollution may not make people feel________.

A. uncomfortable　　 B. upset　　 C. mad　　 D. pleased

4.Which of the following is NOT true?

A. Listening to loud music may do some harm to your hearing.

B. Noise is a kind of unwanted sound.

C. We needn't watch out for the construction site noise.

D. Everybody has a duty to keep a quiet environment.

5.What's the best title for the passage?
