Question

8．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（損壞）．
       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（細胞） in the inner ear．The cells can tell different sounds through vibration（振動）．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．

Answer 1

分析 文章大意：這是一篇議論文．主要講經(jīng)常用耳機聽音樂會對耳朵造成一定的傷害．耳朵內(nèi)的細胞很脆弱，很容易損壞，因此聽音樂的時間最好不要超過一個小時．也不要放太大的聲音，用這樣的方式會使你更好的享受音樂．

解答 49．答案：C．細節(jié)理解題．根據(jù)第一段Do you often turn up the music when you're using earphones？If so，your hearing may have been damaged（損壞）．當你使用耳機時，你經(jīng)常大聲播放音樂嗎？如果是這樣的話，你的聽力可能已經(jīng)受損．可知，聽大聲音的音樂會損失聽力，選C．
50．答案：B．細節(jié)理解題．根據(jù)第三段第一句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克魯格博士說，把音樂放下來，把每天的收聽時間限制在一小時以內(nèi)，這樣可以挽救很多人的聽力．可知，一天聽一小時．選B．
51．答案：A．詞意猜測題．根據(jù)后面they get damaged easily and even die 他們很容易損壞，甚至死亡．可知耳朵內(nèi)的細胞太"脆弱"了．因此選A．
52．答案：A．主旨大意題．根據(jù)最后一段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．沒有人想失去他們的聽力！因此，下一次當你聽音樂，確保它不是太大聲，只聽不到一個小時．及第三段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克魯格博士說，把音樂放下來，把每天的收聽時間限制在一小時以內(nèi)，這樣可以挽救很多人的聽力．可知，短文主要告訴我們應(yīng)該"把音樂放下來可以挽救年輕人的聽力"，故選A．

點評 閱讀題型，要注重句子與句子之間、段落與段落之間邏輯關(guān)系以及對篇章的整體理解．根據(jù)所給問題選擇正確選項完成試題．
