Question

Do you like listening to music? Do you often turn up the music when you’re using earphones? If so, your hearing may have been damaged(损坏).

The World Health Organization (WHO) is worried that 1.1 billion children and young people are damaging their hearing by listening to loud music. Nearly half the young people in developed countries may lose their hearing because of the "unsafe use" of music players, including smartphones. Loud music in nightclubs, parties and at sports also make it worse. The WHO advises young people to listen to music for just one hour a day. Dr. Etienne Krug told BBC: "What we're trying to do is to draw people's attention to a problem that is not talked about enough." He said it's easy to solve this problem.

Dr. Krug said keeping the music down and limiting (限制) the listening time to less than one hour a day would save a lot of people's hearing. However, he also said, "Even an hour can be too much if the music is too loud.” Ralph Holme, a researcher, explained how loud noise can damage ears. He said: "Loud sounds damage your hearing by killing off thousands of little hair cells(细胞) in the inner ear. The cells can tell different sounds through vibration(振动). But they are very fragile — they get damaged easily and even die if they vibrate too much because of loud sounds for too long.” He warned: "The bigger problem is they don't grow back and the ear can no longer get sound."

No one wants to lose their hearing! Therefore, next time when you listen to music, make sure it's not too loud and only listen for less than an hour. You can enjoy your music much better in this way.

【解析】

试题分析：这篇短文中作者介绍了大声并且长时间听音乐对听力是有损害的。因此建议年轻人把音量调小并且把听的时间限制在一小时之内。

1.C细节理解题。By using smartphones是通过使用智能手机；By going to the party是通过参加聚会；By talking with friends是通过和朋友谈话；By listening to loud music是通过听大声的音乐。根据第一段The World Health Organization (WHO) is worried that 1.1 billion children and young people are damaging their hearing by listening to loud music可知世界健康组织担忧11亿孩子及年轻人正在通过大声地听音乐损害他们的听力。故选C。

2.B细节理解题。根据第二段The WHO advises young people to listen to music for just one hour a day.可知世界健康组织建议年轻人每天仅听一个小时的音乐。故选B。

3.A词义猜测题。根据最后一段The cells can tell different sounds through vibration(振动). But they are very fragile — they get damaged easily and even die if they vibrate too much because of loud sounds for too long.可知细胞可以通过振动区分不同的声音。但是它们很脆弱—它们很容易被损害甚至死亡如果它们由于长时间的巨大声音振动得太频繁。联系上下文可推断出fragile表示脆弱的。clever聪明的；small小的；strong强壮的；weak弱的；因此跟A项意思最接近。故选A。
