【文章內(nèi)容簡介】 Loud noise is harmful to the inner二Most of us are bon with about 16,000 hair cells （聽毛細胞） 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, it39。s hard to get your hearing back. Some people might think that their music isn39。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 alight feel unfortable The safe level for most sound is below 80 dB for up to 40 hours a week. A level of 80 dB is about equal to （相當于） the noise of a subway. Here is some advice on safe listening. Over—the—ear headphones （頭戴式耳機） are better than in—ear ones. They do a better job of stopping outside noise, so you can listen at a lower volume. Don39。t listen to loud music on your headphones for a long time. Follow the 60:60 rule: listen to music at 60 percent of your headphones39。 maximum volume for no more than 60 minutes a day.（1）It is safe to listen to sounds that are louder than 100 dB for 15 minutes （2）Listening to loud noise for a long time can cause some hair cells in the inner ear to die. （3）From the fourth paragraph, we know people don39。t always realize how loud their music is. （4）In—ear headphones are better than over—the—eat ones because they can stop more outside noise. （5）This article mainly tells us why ears are an important part of our bodies. 【答案】 （1）0（2）1（3）1（4）0（5）0 【解析】【分析】文章大意： 本文主要講述了聽大音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這些細胞工作太猛，并使其中一些細胞死亡。這就是人們聽力損失的原因。 （1）判斷正誤題。根據(jù) It is not safe to listen to sounds that are louder than 85 dB （分貝） for eight hours or 100 dB for 15 minutes. 可知挺高于85分貝八個小時或者100分貝15分鐘是不安全的。故答案為錯誤。 （2）判斷正誤題。根據(jù) However, listening to loud noise for a long time can make these cells work too hard and cause some of them to die. 可知聽大聲的噪音很長時間能使這些耳毛細胞工作太猛，造成一些耳毛細胞死亡，故答案為正確。 （3）判斷正誤題。根據(jù) if you are in a noisy place like the subway, you might turn up your music too loud without realizing it. 可知如果你在像地鐵這樣吵鬧的地方，你可能無意識的把聲音調(diào)到太大，可知第四段告訴我們?nèi)藗儾豢偸悄芤庾R到他們的音樂有多大聲，故答案為正確。 （4）判斷正誤題。根據(jù) Over—the—ear headphones （頭戴式耳機） are better than in—ear ones.

Last month, China started its official online mapping service, Map World. Through this free online service users can fly over mountains and valleys around the world and search for restaurants and traffic information across the country for free, said Xu Deming, director of the State Bureau of Surveying and Mapping （SBSM）. The bureau, which does China39。s surveying and mapping work, is in charge of the Map World project. Users can get into Map World through or and search for 2 and 3D images from across the world. The home page shows a view of the Great Wall. It took about two years to prepare the service with all the satellite（衛(wèi)星） images taken from 2006 to 2010, said Jiang Jie, director of the database department（數(shù)據(jù)庫部門） under SBSM. The technology（技術(shù)） and website are still at an early stage. The images from inside China are detailed. Users can see close pictures of roadsides. But the views of places outside China are less clear. Service providers have more than 80 machines, with the ability to deal with 10 million requests （請求） daily, while Google Earth, Google39。s mapping service, has thousands of machines, Jiang said. Our map service can update（更新） data about twice a year, but Google Earth can update its information every couple of minutes, through satellites, Jiang said. The bureau said it will continue developing Map World. At the same time, you can have a try for yourself. Some users have given their opinions about the service after trying it. One student in Beijing said that Map World even shows the small bookstore near her school.（1）What is the main purpose of the first paragraph?
