初中英语阅读理解
Noise pollution is doing much harm to our health now．Noise 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)．While watching TV,they keep the volume up．But they haven’t realized that the noise is weakening(减弱)their hearing．In fact,the noise not only influences each member in the family,but also influences the ne ighbors．
Noise pollution is a source of misery to people in our society．If people are often disturbed by it,they may feel uncomfortable or sad．What’s worse,the noise can make people mad sometimes．If a worker works in a printing factory for too long,his hearing loss is much faster than a common person working in a quieter environment．So everybody must pay attention to noise pollution．
The following simple ways can be used to avoid(避免)noise：
★Try to use less noisy equipment(设备)(e．g．washing machines)．
★Keep the volume of TV,radio and music as low as possible,especially late at night．
★If your dog barks when left alone,make sure to leave it with a friend．
★If you have a party,tell your neighbors in advance(提前)and keep the noise a little lower．
I think the local environment protecting department(部门)will take measures to control the noise levels．But it’s everybody’s duty to keep a quiet environment.
The noise can do harm to people's hearing when___
A.they listen to musc on an MP3 player
B.they listen to loud music
C.they watch TV
D.they use earphones
抱歉，第二行应该为：
More and more students enjoy listening to music with earphones．When they listen to MP3 players，they like

很高兴为你
本题答案是：B
从文中第三行”When they listen to MP3 players,they like to turn up the volume(音量)．“可以得到答案~
A、C选项,根据文意,如果是正常看电视或者听MP3,噪声是不会影响人们健康的.原因在于看电视或者听MP3时,人们常常把音量调的太高了~所以排除A、C选项；
D选项,用耳机具体会产生什么影响,文中没有提及,故也排除~
这样解说希望楼主能理解,不清楚的话欢迎追问交流,希望能帮到楼主~
再问： 对不起，刚才打字有误，现已改正，请重新解释一下为何不选D。
再答： 楼主你好~根据句意的话，喜欢用耳机听音乐并不会造成什么危害（文中没有提及），关键在于是听歌的时候音量太大。这点从下文看电视音量开太大也会造成危害中可以得到印证~简单来说，对人们的听力造成危害的原因就是听太大的声音~
