你的耳朵可以让你听到许多不同的声音，有些声音听起来很舒服，有些听起来不那么愉快，声音越响，你听的越久，就越有可能对你的听力造成伤害，这篇文章就向读者介绍了远离噪音的重要性以及推荐做法。
【1】句意：我们可以从第一段知道什么？A.有两种不同的声音。B.所有的声音听起来都很愉快。C.有些声音可能会损害你的听力。D.长时间听更响亮的声音对你有好处。原文“The louder the sound and the longer you listen to it，the more possible it is to cause damage(损害) to your hearing.”（声音越大，听到的时间越长，就越有可能对听力造成伤害。）说明有的声音是会损害听力的，C选项正确，故选C。

【3】句意：120的声音对你的听力有害。A. 0；B. 60 ；C. 80；D. 120。原文“The sound at 85 decibels and above may harm your hearing.”（85分贝及以上的声音可能会损害你的听力。）说明120的声音是会对你的听力有害，故选D。
【4】句意：烟花的声音约为140分贝。A.繁忙的城市交通；B.洗衣机；C.火箭发射；D.烟花。通过观察文中的图示，发现140对应的是fireworks（烟火），说明烟花的声音约为140分贝，故选D。
