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（分贝）．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 本文主要介绍噪音产生的原因以及噪音对人们产生的危害．也谈到了一些国家正在努力制定法规来阻止噪音的产生．

解答 66--70 FEGAD
66．F 考查上下文理解判断能力．根据前文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，一个普通城市的声音大得足够对人的听力产生严重的伤害，下文应是：这种情况正在变得更糟糕．故选F．
67．E 考查上下文理解判断能力．根据前文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，一个人的耳朵不能明确地判断噪音的响度，下文应是：既然我们不能测量噪音的上升或下降，我们从来不知道我们处在什么危险中．
68．G 考查上下文理解判断能力．根据前文It has been known that loud noises，over a period of time，cause loss of sleep，anger，and many other problems可知，已经知道大的噪音在一段时间内能产生睡眠不足，愤怒和许多其它的问题，那下文应是列举一些例子．故选G．
69．A 考查上下文理解判断能力．根据下文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，在美国，一些城市的司机因按喇叭要罚款50美元，再犯则失去开车的权力，前文应是：一些国家正在努力制定法律．故选A．
70．D 考查上下文理解判断能力．根据下文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，城市的噪音会是现在的两倍大，上文应是：这会使人们努力工作来阻止城市噪音的增加．故选D．

点评 七选五题型看似简单，实际上有时完全作对并不容易，需要方法和分析能力及足够的耐力，有必要进行专门练习．首先，快速浏览一遍七个备选答案，先确定哪个选项适合放在文章的什么位置．其次，快速浏览文章，确定文章体裁，抓住文章结构，分析篇章结构，找出各段的主题句或主旨大意．其三，注意各选项中出现的句子衔接手段，寻找句中衔接标志词，七选五备选答案中有两个多余的选项，会对文章中两个空的选择构成干扰，这时要特别细致地比对相似选项．最后，用代入法，检查答案是否合理，将所有选择答案放回空白处，通读全文，检查文章内容是否语义连贯合理、紧扣主题，语篇结构是否通顺连贯、具有一致性、合乎逻辑，写作思路是否清晰明了，格式以及用语是否恰当贴切，从而判断选择的答案是否正确．
