Question

4．NOISE
    The people who lived in Rome 2，000 years ago were already talking about the noise in their
city．They couldn't sleep，they said，with all the people and carriages in the streets．For them noise was only a trouble，but for us it has become a real danger．We know that sounds of an ordinary city are loud enough to cause serious harm to the people's hearing--in the United States，one person out of twenty has suffered some hearing loss．（66）FIt has increased greatly in the 20th century with the development of machines．We live
surrounded by loud planes，trucks，buses，radios，machines--that make such loud noises day and
night up to 90 or 100 decibels（分貝）．A usual talk reaches 55 decibels．A jet plane goes to 100
decibels and more．"Pop"music reaches around 118 decibels．At 120 decibels the ear stops
hearing sound，and the ear suffers a lot．
    However，the human ear does not judge clearly the degree of loudness of a noise．A sound ten decibels louder than another one is felt as twice as loud，when，in fact，it is ten times louder．
 （67）EBut it is not only our hearing that is harmed．It has been known that loud noises，over a period of time，cause loss of sleep，anger，and many other problems．（68）GCan anything be done to make our world more quiet？We know how to build quieter machines，if the public wants them．But shop-assistants say that people who buy motorbikes like the loudest ones because they sound more loudly．（69）AIn America the drivers in some cities are fined fifty dollars for honking；they may lose their right to drive if they do it again．People who carry noisy radios in public places may lose them if they are caught with them．（70）DEven so，say the scientists，in twenty years the cities will be twice as loud as they are
today because of the increase of the population．People will have to shout to be heard at the dinner table．Unless，of course，they have all become completely deaf!

A．Some countries are trying to make laws．
B．People will become completely deaf in the future．
C．When a sound is getting louder and louder，our ears are in danger．
D．In fact，it will take everybody's hard work to keep city noises from increasing．
E．Since we cannot measure the increase or decrease of noise，we never know in what danger we are．
F．And all over the world the situation is getting worse all the time since noise increases with the population．
G．Such problems have been found among factory workers，and people who operate loud machines，or often go to pop music concerts．

Answer 1

分析 本文主要介紹噪音產(chǎn)生的原因以及噪音對(duì)人們產(chǎn)生的危害．也談到了一些國(guó)家正在努力制定法規(guī)來(lái)阻止噪音的產(chǎn)生．

解答 66--70 FEGAD
66．F 考查上下文理解判斷能力．根據(jù)前文We know that sounds of an ordinary city are loud enough to cause serious harm to the people's hearing--in the United States，one person out of twenty has suffered some hearing loss可知，一個(gè)普通城市的聲音大得足夠?qū)θ说穆?tīng)力產(chǎn)生嚴(yán)重的傷害，下文應(yīng)是：這種情況正在變得更糟糕．故選F．
67．E 考查上下文理解判斷能力．根據(jù)前文However，the human ear does not judge clearly the degree of loudness of a noise．A sound ten decibels louder than another one is felt as twice as loud，when，in fact，it is ten times louder可知，一個(gè)人的耳朵不能明確地判斷噪音的響度，下文應(yīng)是：既然我們不能測(cè)量噪音的上升或下降，我們從來(lái)不知道我們處在什么危險(xiǎn)中．
68．G 考查上下文理解判斷能力．根據(jù)前文It has been known that loud noises，over a period of time，cause loss of sleep，anger，and many other problems可知，已經(jīng)知道大的噪音在一段時(shí)間內(nèi)能產(chǎn)生睡眠不足，憤怒和許多其它的問(wèn)題，那下文應(yīng)是列舉一些例子．故選G．
69．A 考查上下文理解判斷能力．根據(jù)下文In America the drivers in some cities are fined fifty dollars for honking；they may lose their right to drive if they do it again可知，在美國(guó)，一些城市的司機(jī)因按喇叭要罰款50美元，再犯則失去開(kāi)車(chē)的權(quán)力，前文應(yīng)是：一些國(guó)家正在努力制定法律．故選A．
70．D 考查上下文理解判斷能力．根據(jù)下文Even so，say the scientists，in twenty years the cities will be twice as loud as they are可知，在二十所后，城市的噪音會(huì)是現(xiàn)在的兩倍大，上文應(yīng)是：這會(huì)使人們努力工作來(lái)阻止城市噪音的增加．故選D．

點(diǎn)評(píng) 七選五題型看似簡(jiǎn)單，實(shí)際上有時(shí)完全作對(duì)并不容易，需要方法和分析能力及足夠的耐力，有必要進(jìn)行專(zhuān)門(mén)練習(xí)．首先，快速瀏覽一遍七個(gè)備選答案，先確定哪個(gè)選項(xiàng)適合放在文章的什么位置．其次，快速瀏覽文章，確定文章體裁，抓住文章結(jié)構(gòu)，分析篇章結(jié)構(gòu)，找出各段的主題句或主旨大意．其三，注意各選項(xiàng)中出現(xiàn)的句子銜接手段，尋找句中銜接標(biāo)志詞，七選五備選答案中有兩個(gè)多余的選項(xiàng)，會(huì)對(duì)文章中兩個(gè)空的選擇構(gòu)成干擾，這時(shí)要特別細(xì)致地比對(duì)相似選項(xiàng)．最后，用代入法，檢查答案是否合理，將所有選擇答案放回空白處，通讀全文，檢查文章內(nèi)容是否語(yǔ)義連貫合理、緊扣主題，語(yǔ)篇結(jié)構(gòu)是否通順連貫、具有一致性、合乎邏輯，寫(xiě)作思路是否清晰明了，格式以及用語(yǔ)是否恰當(dāng)貼切，從而判斷選擇的答案是否正確．
