Lesson 2 Spare that spider不要伤害蜘蛛

First listen and then answer the following question.

听录音，然后回答以下问题。

How much of each year do spiders spend killing insects?

Why, you may wonder, should spiders be our friends? Because they destroy so many insects, and insects include some of the greatest enemies of the human race. Insects would make it impossible for us to live in the world; they would devour all our crops and kill our flocks and herds, if it were not for the protection we get from insect-eating animals. We owe a lot to the birds and beasts who 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 do the harm to us or our belongings.

Spiders are not insects, as many people think, nor even nearly related to them. One can tell the difference almost at a glance, for a spider always has eight legs and insect never more than six.

How many spiders are engaged in this work no our behalf? One authority on spiders made a census of the spiders in grass field in the south of England, and he 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 football 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 with only three meals a day. It has been estimated that the weight of all the insects destroyed by spiders in Britain in one year would be greater than the total weight of all the human beings in the country.

New words and expressions

Beast n. 野兽

Census n. 统计数字

Acre n. 英亩

Content adj. 满足的

参考译文

你可能会觉得奇怪，蜘蛛怎么会是我们的朋友呢？因为它们能消灭那么多的昆虫，其中包括一些人类的大敌，要不是人类受一些食虫动物的保护，昆虫就会使我们无法在地球上生活下去，昆虫会吞食我们的全部庄稼，杀死我们的成群的牛羊。我们要十分感谢那些吃昆虫的鸟和兽，然而把它们所杀死的昆虫全部加在一起也只相当于蜘蛛所消灭的一小部分。此外，蜘蛛不同于其他食虫动物，它们丝毫不危害我们和我们的财物。

许多人认为蜘蛛是昆虫，但它们不是昆虫，甚至与昆虫毫无关系。人们几乎一眼就能看出二者的差异，因为蜘蛛都是8条腿，而昆虫的腿从不超过6条。

有多少蜘蛛在为我们效力呢？一位研究蜘蛛的权威对英国南部一块草坪上的蜘蛛作了一次调查。他估计每英亩草坪里有225万多只蜘蛛。这就是说，在一个足球场上约有600万只不同种类的蜘蛛。蜘蛛至少有半年在忙于吃昆虫。它们一年中消灭了多少昆虫，我们简直无法猜测，它们是吃不饱的动物，不满意一日三餐。据估计，在英国蜘蛛一年里所消灭昆虫的重量超过这个国家人口的总重量。

Though Jimmy agreed to go at once, Jumbo refused to move. Fifteen policemen had to push very hard to get him off the main street. The police had adifficult time, but they were most amused .‘Jumbo must weigh a few tons,’said a policemen afterwards, ‘soit was fortunate that we didn't have to carry him.

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.

新概念第二册课后题答案详解Lesson65

新概念第二册课后题答案详解Lesson65 新概念英语第二册课后习题Lesson 65 1. a 根据课文第6-8行A policeman approached Jimmy and told him he ought to have gone alone a side street 能够推断,只有a. He had gone down a side street 符合课文所暗示的情景,其他3个选择都与课文的实际意义不符合. 2. d 根据课文第9-10行 The police had a difficult time, but they were most amused 只有d. The police had a difficult time getting Jumbo off the main street 与课文所描述的情景相符，其他3个选择都与课文事实不符。 3. b a. seemed as 不是准确表达方式，应该是seem as if ( 好像是); b. looked like 意思是“看上去像是”; c. look ed as 不是准确表达方式，应该是look as if (看来好像); d. seem (似乎，好像)后面常跟动词不定式或形容词做表语;只有b. looked like 最合乎题目意思和语法，所以选b. 4. b 该句的谓语should have known 表示“本应该知道但是却不知道”，所以b. but he didn't(但是他却没做到)是准确的答案。其他3个选择都与该句的谓语动词含义不符合。 5. c

前一句中的谓语ought to have gone 意思为“本应该走但实际却没有走”。该句需要选一个同前一句动词含义相同的短语。 a. should do (理应做); b. should be doing(应正在做); c. should have done(本应该做); d. should(应该); 只有c.与 ought to have done 意义相同，所以应该选c. 6. a 前一句的谓语动词，must weigh 意思是“一定有...重”，表示推测，该句需要一个与前一句谓语含义相同的短语。 a. probably weighs (可能重)， b. has to weigh(必须重), c. ought to weigh(理应重)， d. should weigh(理应重)，只有a.与must weigh 的含义相符合，所以选a. 7. a 只有选a. Did they have 最合乎语法，因为have to 作情态助动词时，其疑问句形式应该用助动词do,如do you have to..., 所以选a. 其他3个选择都不符合语法。 8. d 前一句中的set off 意思为“启程”，“出发”，该句只有选出同它含义相同的词或词组才能同前一句意义相符合。 a. ran(跑); b. walked(步行，走); c. rode(骑); d. started his journey (启程，开始旅程)这4个选择中只有d.同set off 的意义相同，所以选d.

Lesson 39 Am I all right? 我是否痊愈？ Why did Mr. Gilbert telephone Dr. Millington? While John Gilbert was in hospital, he asked his doctor to tell him whether his operation had been successful, but the doctor refused to do so. The following day, the patient asked for a bedside telephone. When he was alone, he telephoned the hospital exchange and asked for Doctor Millington. When the doctor answered the phone, Mr. Gilbert said he was inquiring about a certain patient, a Mr. John Gilbert. He asked if Mr. Gilbert's operation had been successful and the doctor told him that it had been. He then asked when Mr. Gilbert would be allowed to go home and the doctor told him that he would have to stay in hospital for another two weeks. Then Dr. Millington asked the caller if he was a relative of the patient. 'No,' the patient answered, 'I am Mr. John Gilbert.' 参考译文当约翰.吉尔伯特住院的时候，他问医生他的手术是否成功，但医生拒绝告诉他。第二天，这位病人要了一部床头电话。当房里只剩他一个人时，他挂通了医院的交换台，要求与米灵顿医生讲话。当这位医生接过电话时，吉尔伯特先生说他想询问一个病人的情况，是一位名叫约翰.吉尔伯特的先生。他问吉尔伯特先生的手术中否成功，医生告诉他手术很成功。然后他又问吉尔伯特先生什么时候可以回家，医生说他在医院还必须再住上两个星期。之后，米灵顿医生问打电话的人是否是病人的亲属。“不是，”病人回答说，“我就是约翰.吉尔伯特先生。” 一、New words and expressions 生词和短语 operate V． 1)操作，操纵（机器等），运作，运转( control，run) operate a machine操纵一台机器 operate the lift开电梯例：This sewing machine doesn't operate properly. 这台缝纫机不太好用了。 2)经营，管理(run, manage) operate a company经营一家公司例: The company operate ten factories. 这家公司管理十个厂子。 The business operate in various counties.

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.
