Question

【題目】 Do you like music? Do you often listen to it at loud volumes? You should know that this habit is bad for your hearing, according to the World Health Organization (WHO).

Over 1 billion young people are at risk of hearing loss due to listening to loud noise for long periods of time, WHO said. 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 decibels 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 born with about 16,000 hair cells in our inner ears. These cells detect 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.

Some people might think that their music isn’t all that loud. But this can depend on where you are. For example, if you are in a noisy place like the subway, you might turn up your music too loud without realizing it. Later, when you listen to it at the same volume in a quiet place, you might feel uncomfortable.

WHO said the “safe level” for most sound is below 80 decibels for up to 40 hours a week. A level of 80 decibels is nearly the same as the noise of a subway.

Answer 1

【答案】

【1】C

【2】B

【3】B

【4】D

【解析】

本文主要講述了聽大量音樂的習慣對聽力有害。世界衛(wèi)生組織稱，超過10億的年輕人在聽力方面存在問題，因為他們長時間大聲聆聽。聯(lián)合國有安全聆聽標準，聽八十小時大于85分貝或15分鐘大聲100分鐘的聲音是不安全的。長時間聆聽大聲的聲音可能會使聽力細胞工作太猛，并使其中一些細胞死亡。這就是人們聽力損失的原因。

【1】細節(jié)理解題。根據“Listening to music or watching a TV show at loud volumes can harm your hearing.”可知大聲聽音樂或看電視節(jié)目會損害你的聽力。故選C。

【2】細節(jié)理解題。根據“The sound of a busy road is about 85 dB…”可知繁忙道路的聲音約為85分貝。故選B。

【3】細節(jié)理解題。根據“However, listening to loud noise for a long time can make these cells work too hard and cause some of them to die.”可知長時間聽太大的噪音會使這些細胞工作過度，會導致一些細胞死亡。故選B。

【4】推理判斷題。根據“…if you are in a noisy place like the subway, you might turn up your music too loud without realizing it.”如果你在像地鐵這樣嘈雜的地方，你可能會把音樂開得太大而沒有意識到。可知人們并不總是意識到他們的音樂聲音有多大。故選D。

本題考查閱讀理解，涉及細節(jié)理解題及推理判斷題，其中細節(jié)理解題要從文中找到答案，仔細對比原文中的信息，如小題1、小題2、小題3；推理判斷題要聯(lián)系上下文，閱讀每一個選項，根據文中信息做必要的推斷，如小題4，A、B、C三個選項在文中都沒有提及，只有D選項可以找到原文信息推斷出答案。
