Lesson 25 Non-auditory effects of noise 噪音的非听觉效应

Many people in industry and the Services, who have practical experience of noise, regard any investigation of this question as a waste of time; they are not prepared even to admit the possibility that noise affects people. On the other hand, those who dislike noise will sometimes use most inadequate evidence to support their pleas for a quieter society. This is a pity, because noise abatement really is a good cause. And it is likely to be discredited if it gets to be associated with bad science.

One allegation often made is that noise produces mental illness. A recent article in a weekly newspaper, for instance, was headed with a striking illustration of a lady in a state of considerable distress, with the caption 'She was yet another victim, reduced to a screaming wreck '. On turning eagerly to the text, one learns that the lady was a typist who found the sound of office typewriters worried her more and more until eventually she had to go into a mental hospital. Now the snag in this sort of anecdote is of course that one cannot distinguish cause and effect. Was the noise a cause of the illness, or were the complaints about noise merely a symptom? Another patient might equally well complain that her neighbors were combining to slander her and persecute her, and yet one might be cautious about believing this statement.

What is needed in the case of noise is a study of large numbers of people living under noisy conditions, to discover whether they are mentally ill more often than other people are. The United States Navy, for instance, recently examined a very large number of men working on aircraft carriers: the study was known as Project Anehin. It can be unpleasant to live even several miles from an aerodrome; if you think what it must be like to share the deck of a ship with several squadrons of jet aircraft, you will realize that a modern navy is a good place to study noise. But neither psychiatric interviews nor objective tests were able to show any effects upon these American sailors. This result merely confirms earlier American and British studies: if there is any effect of noise upon mental health it must be so small that present methods of psychiatric diagnosis cannot find it. That does not prove that it does not exist; but it does mean that noise is less dangerous than, say, being brought up in an orphanages--which really is a mental health hazard. (NCE Book Four)

Lesson1 We can read of things that happened 5,000 years ago in the Near East, where people first learned to write. But there are some parts of the world where even now people cannot write. The only way that they can preserve their history is to recount it as sagas--legends handed down from one generation of story-tellers to another. These legends are useful because they can tell us something about migrations of people who lived long ago, but none could write down what they did. Anthropologists wondered where the remote ancestors of the Polynesian peoples now living in the Pacific Islands came from. The sagas of these people explain that some of them came from Indonesia about 2,000 years ago. But the first people who were like ourselves lived so long ago that even their sagas, if they had any, are forgotten. So archaeologists have neither history nor legends to help them to find out where the first 'modern men' came from.

NEW CONCEPT ENGLISH (IV) (new version) 2 Lesson 1 Finding Fossil man We can read of things that happened 5,000 years ago in the Near East, where people first learned to write. But there are some parts of the world where even now people cannot write. The only w ay that they can preserve their history is torecount it as sagas--legends handed down from one generation of story-tellersto another. These legends are useful because they can tell us somethin g aboutmigrations of people who lived long ago, but none could write down what they did. Anthropologists wondered where the remote ancestors of the Polynesianpeoples now living in th e Pacific Islands came from. The sagas of these peopleexplain that some of them came from Indo nesia about 2,000 years ago.But the first people who were like ourselves lived so long ago that ev en theirsagas, if they had any, are forgotten. So archaeologists have neither history nor legends to help them to find out where the first 'modern men' came from.Fortunately, however, ancient me n made tools of stone, especially flint, becausethis is easier to shape than other kinds. They may also have used woodand skins, but these have rotted away. Stone does not decay, and so the tool s oflong ago have remained when even the bones of the men who made them have disappeared without trace. 3 Lesson 2 Spare that spider Why, you may wonder, should spiders be our friends ? Because they destroy somany insects, and insects include some of the greatest enemies of the humanrace. Insects would make it impossible for us to live in the world; they woulddevour all our crops and kill our flocks and herds, if it were not for the protectionwe get from insect-eating animals. We owe a lot to the birds and beasts wh o eat insects but all of them put together kill only a fraction of the number destroyed by spiders. Moreover, unlike some of the other insect eaters, spiders never dothe least harm to us or our bel ongings.Spiders are not insects, as many people think, nor even nearly related to them.One can t ell the difference almost at a glance for a spider always has eight legsand an insect never more th an six.How many spiders are engaged in this work on our behalf ? One authority on spiders made a census of the spiders in a grass field in the south of England, andhe estimated that there were more than 2,250,000 in one acre, that is something like 6,000,000 spiders of different kinds on a f ootball pitch. Spiders are busy for at least half the year in killing insects. It is impossible to make more than the wildest guess at how many they kill, but they are hungry creatures, not content wi th only three meals a day. It has been estimated that the weight of all the insects destroyed by spi ders in Britain in one year would be greater than the total weight of all the human beings in the c ountry.T. H.

新概念英语第三册语法解析:类比法、夸张法、排比法

新概念英语第三册语法解析:类比法、夸张法、排比法 类比法(Analogy)是一种词义修辞格,把两种本质上不相同的事物就其某方面的共同 点进行比较,通过比喻说明某种道理或描绘某种复杂情况。例如,Lesson 27的第一句, “It has been said that everyone lives by selling something.” 作者把人们生活工作的方式类比成销 售货物的方式,每个人都是一定意义上的推售员,抽象的为谋生而付出的努力被比喻成具体的可供售卖的货物。通过这样的类比,读者找到了联系的线索,加深对句子的理解并引起共鸣。假如我们要借助类比描绘英语的作用,我们就可以说,“What English means to a student is what weapons mean to the soldiers who fight in the battlefield.” 或“If we obtain English proficien cy, we obtain the key which leads us to more knowledge and opportunities.” 夸张法(hyperbole)也是词义修辞,刻意地夸大或缩小把事物的特征,在数量,形状和 程度上加以渲染,“言过其实”地使事物的本质特征更好地呈现出来,给人强烈的印象。Lesson 49, 作者谈到阿姨家的仆人数量时提及”an army of servants (仆人大军)” and “the shifting population(流动人口)”, 把Bessie导致布丁砸在桌上的小意外说成“catastrophe (大 灾难)”, 不难看出这些都是夸张的例子。如果我们的朋友多不胜数,我们也可以自豪地说,“I have an army of friends.”, 但是如果他们都是“the shifting population who just come and go into my life without even a hello or goodbye (他们只是连招呼不打就来来去去的流动人口)”,那么这样的友情带来的只是一个“catastrophe”, 因为没有得到真正的知己。 排比法(Parallelism),属于结构修辞,以语法结构对称来突出意义,增添气势。Lesson 51,阐述Bagrid预测计算机的功能, 文中出现了连续四个排比,充分证明了Bagrid非凡的 眼光,“Bagrid foresaw a time when computers would be small enough to hold in the hand, when they would be capable of providing information about traffic jams…, when they would be used in hospital…, when they would relieve office workers and accountants of dull, repetitive clerical work..”排比是最常用的修辞之一,排比项通常以三项为起点,控制于五项之内。 结合一个写大学教育的主题,以下的排比句跃然纸上, “University is the place where we absorb the most comprehensive knowledge, where we encounter friends of lifetime, where we cultivate our characters and personalities, where we create the most impressive part of our life.

新概念英语第四册第二十单元课文原文

新概念英语第四册第二十单元课文原文 Lesson 20 Snake poison 蛇毒How it came about that snakes manufactured poison is a mystery. Over the periods their saliva, a mild, digestive juice like our own, was converted into a poison that defies analysis even today. It was not forced upon them by the survival competition; they could have caught and lived on prey without using poison just as the thousands of non-poisonous snakes still do. Poison to a snake is merely a luxury; it enables it to get its food with very little effort, no more effort than one bite. And why only snakes ? Cats, for instance, would be greatly helped; no running rights with large, fierce rats or tussles with grown rabbits just a bite and no more effort needed. In fact it would be an assistance to all the carnivorae--though it would be a two-edged weapon -When they fought each other. But, of the vertebrates, unpredictable Nature selected only snakes (and one lizard). One wonders also why Nature, with some snakes concocted poison of such extreme potency. In the conversion of saliva into poison one might suppose that a fixed process took place. It did not; some

新概念英语第1册第103-104课重点语法.doc

新概念英语第 1 册第 103-104课重点语法 第 103-104 课的内容: 一、重要句型或语法 1、副词 too 、very 和 enough 1)too 和 very 都有“很、非常”的含义,但too 一般都用来修饰 消极或负面的形容词或副词,而very 则是偏中性的。 2)enough 修饰名词时,放在前面,如enough water/books; 修饰 形容词或副词时,则要后置,如good enough/well enough。 二、课文主要语言点 How was the exam, Richard? Not too bad.1) 句中之所用was, 2)not too 是因为 Gary 问的是 Richard 之前参加过的考试的情况。 bad,不太糟糕、不算太坏。往往说明结果还能够。 I think I passed in English and Mathematics.1) 能够问学生 句中的 pass 为什么用过去式 ( 因为是在描述过去发生的事情) 。 2) 注 意 mathematics 的重音和拼写,能够简写为 math( 美式英语 ) 或 maths( 英式英语 ) 。另外,学科的单词首字母一般都要大写。 The questions were very easy. 可由easy 引出difficult 。 ,用来提问或建议。本句问的How about you, Gary?how about 是 Gary 考试的情况。 The English and Maths papers weren't easy enough for me.paper 表示纸张时,是不可数名词。本句中的paper 指的是试卷,是可数名词,所以要用复数 s。 I hope I haven't failed.1)I hope后接宾语从句,省略that 。 2)fail,失败。经常用来表示考试不及格,而且要注意:如果要表达

新概念英语第三册重点语法总结:名词性从句

新概念英语第三册重点语法总结:名词性从句 王牌要点:通常由 that或疑问词导出。 1. How some mammals came to live in the sea is not know.(主语从句) 2. The attorney told his client that they had little chance of winning the case.(宾语从句) 3. The problem is what we'll do next.(表语从句) 4. We have no idea that he has come back.(同位语从句) 同位语(Appositive): 同位语是英语语法的重点内容,也是各类考试中的一个考点,同时,在写作中正确运用同位语可以使你的句型更加简洁得体。 《新概念英语》第三册第一课有这样一个句子: When reports came into London zoo that a wild puma had been spotted forty-five miles south of London, they were not taken seriously.

(当伦敦动物园接到报告说,在伦敦以南45英里处发现一只美洲狮时,这些报告并没 有受到重视。) 在这里,a wild puma had been spotted forty-five miles south of London就是同位语从句,它本来应该放在“reports”后面,这里却被放在了谓语成分 came into London zoo的后面, 目的是让句型显得更为稳重。 I.简单记忆:同位语从句,就是对某些名词做进一步的解释的句子。 I was greatly shocked when I heard the news that his father died yesterday. (that 引导的句子解释了news的内容,注意:that不做任何成分) We have to face the fact that the weather is unexpectedly bad. (that 引导的句子解释了fact的内容) II.联想记忆: 能接同位词从句的名词有:belief(信仰),fact,idea,doubt,rumor(谣言), evidence(证据),conclusion(结论),suggestion(建议),problem,order,answer, discovery(发现)explanation(解释),principle(原则),possibility(可能性),truth,promise(承诺),report(报告),statement(声明),knowledge(知识),opinion(观点),likelihood(可能性) [大声朗读三遍,背下即可。]

新概念英语第四册课文:Lesson4

新概念英语第四册课文:Lesson4 【课文】 First listen and then answer the following question. 听录音,然后回答以下问题。 How did Vera discover she had this gift of second sight? Several cases have been reported in Russia recently of people who can read and detect colours with their fingers, and even see through solid doors and walls. One case concerns an eleven-year-old schoolgirl, Vera Petrova, who has normal vision but who can also perceive things with different parts of her skin, and through solid walls. This ability was first noticed by her father. One day she came into his office and happened to put her hands on the door of a locked safe. Suddenly she asked her father why he kept so many old newspapers locked away there, and even described the way they were done up in bundles. Vera's curious talent was brought to the notice of a scientific research institute in the town of Ulyanovsk, near where she lives, and in April she was given a series of tests by a special commission of the Ministry of Health of the Russian Federal Republic. During these tests she was able to read a newspaper through an opaque screen and, stranger still, by moving her elbow over a child's game of Lotto she was able to describe the figures and colours printed on it; and, in another instance, wearing stockings and slippers, to make out with her foot the outlines and colours of a picture hidden under a carpet. Other experiments showed that her knees and

NEW CONCEPT ENGLISH(IV) (new version) 2 Lesson1Finding Fossil man We can read of things that happened5,000years ago in the Near East,where people first learned to write.But there are some parts of the world where even now people cannot write.The only w ay that they can preserve their history is torecount it as sagas--legends handed down from one generation of story-tellersto another.These legends are useful because they can tell us somethin g aboutmigrations of people who lived long ago,but none could write down what they did. Anthropologists wondered where the remote ancestors of the Polynesianpeoples now living in th e Pacific Islands came from.The sagas of these peopleexplain that some of them came from Indo nesia about2,000years ago.But the first people who were like ourselves lived so long ago that ev en theirsagas,if they had any,are forgotten.So archaeologists have neither history nor legends to help them to find out where the first'modern men'came from.Fortunately,however,ancient me n made tools of stone,especially flint,becausethis is easier to shape than other kinds.They may also have used woodand skins,but these have rotted away.Stone does not decay,and so the tool s oflong ago have remained when even the bones of the men who made them have disappeared without trace. 3 Lesson2Spare that spider Why,you may wonder,should spiders be our friends?Because they destroy somany insects,and insects include some of the greatest enemies of the humanrace.Insects would make it impossible for us to live in the world;they woulddevour all our crops and kill our flocks and herds,if it were not for the protectionwe get from insect-eating animals.We owe a lot to the birds and beasts wh o eat insects but all of them put together kill only a fraction of the number destroyed by spiders. Moreover,unlike some of the other insect eaters,spiders never dothe least harm to us or our bel ongings.Spiders are not insects,as many people think,nor even nearly related to them.One can t ell the difference almost at a glance for a spider always has eight legsand an insect never more th an six.How many spiders are engaged in this work on our behalf?One authority on spiders made a census of the spiders in a grass field in the south of England,andhe estimated that there were more than2,250,000in one acre,that is something like6,000,000spiders of different kinds on a f ootball pitch.Spiders are busy for at least half the year in killing insects.It is impossible to make more than the wildest guess at how many they kill,but they are hungry creatures,not content wi th only three meals a day.It has been estimated that the weight of all the insects destroyed by spi ders in Britain in one year would be greater than the total weight of all the human beings in the c ountry.T.H.GILLESPIE Spare that Spider from The Listene Lesson3Matterhorn man Modern alpinists try to climb mountains by a route which will give them goodsport,and the more
