三、阅读理解(共 20 小题,每小题 2 分,满分 40 分)
(A)
Do you often listen to music at loud volumes ( 音量 )? You should know that this habit is
bad for your hearing. Over 1 billion young people are at risk of hearing loss ( 听力丧
失 ) ,because of listening to loud noise for long periods of time. Listening to music or
watching a TV show at loud volumes can harm your hearing.
The United Nations has standards for safe listening. It is not safe to listen to sounds that
are louder than 85 dB ( 分贝 ) for eight hours or 100 dB for 15 minutes. The sound of a busy
road is about 85 dB and the sound of a rock concert can be about 100 dB .
Loud noise is harmful to the inner ear. Most of us are bon with about 16,000 hair cells
( 听毛细胞 ) in our inner ears. These cells notice sounds. However, listening to loud noise for
a long time can make these cells work too hard and cause some of them to die. This is what
causes hearing loss. Once this happens, it's hard to get your hearing back.
