研究生英语精读教程第三版下第三单元
Unit Three Evolution and Natural Selection［1］The idea of evolution* was known to some of the Greek philosophers. By the time of Aristotle①, speculation* had suggested that more perfect types had not only followed less perfect ones but actually had developed from them. But all this was guessing; no real evidence was forthcoming*. When, in modern times, the idea of evolution was revived*, it appeared in the writings of the philosophers – Bacon①, Descartes②, Leibniz③ and Kant④. Herbert Spencer① was preaching* a full evolutionary doctrine* in the years just before Darwin's② book was published, while most naturalists would have none of it. Nevertheless a few biologists ran counter to the prevailing* view, and pointed to such facts as the essential unity of structure in all warm-blooded animals.［2］The first complete theory was that of Lamarck①(1744～1829), who thought that modifications* due to environment, if constant and lasting, would be inherited and produce a new type. Though no evidence for such inheritance was available, the theory gave a working hypothesis* for naturalists to use, and many of the social and philanthropic* efforts of the nineteenth century were framed on the tacit* assumption that acquired improvements would be inherited.［3］But the man whose book gave both Darwin and Wallace the clue was the Reverend* Robert Malthus① (1766～1834),sometime curate* of Albury in Surrey. The English people were increasing rapidly, and Malthus argued that the human race tends to outrun its means of subsistence* unless the redundant* individuals are eliminated. This may not always be true, but Darwin writes:［4］In October 1838,I happened to read for amusement Malthus on Population, and being well prepared to appreciate the struggle for existence which everywhere goes on, from long continued observation of the habits of animals and plants, it at once struck* me that, under these circumstances, favorable variations* would tend to be preserved, and unfavorable ones to be destroyed. The result of this would be the formation of new species. Here then I had a theory by which to work.［5］Darwin spent twenty years collecting countless facts and making experiments on breeding* and variation in plants and animals. By 1844 he had convinced himself that species are not immutable*, but worked on to get further evidence. On 18 June 1858 he received from Alfred Russell Wallace a paper written in Ternate, in the space of three days after reading Malthus's book. Darwin saw at once that Wallace had hit upon the essence of his own theory. Lyell① and Hooker②arranged with the Linnaean③Society to read on July 1st 1858 Wallace's paper together with a letter from Darwin and an abstract* of his theory written in 1844.Then Darwin wrote out an account of his labors, and on 24th November 1859 published his great book The Origin of Species.［6］In any race of plants or animals, the individuals differ from each other in innate* qualities. Darwin offered no explanation of these variations, but merely accepted their existence. When the pressure of numbers or the competition for mates* is great, any variation in structure which is of use in the struggle has "survival value" and gives its possessor an improved chance of prolonging life and leaving offspring. That variation therefore tends to spread through the race by the elimination of those who do not possess it, and a new variety or even species may be established. As Huxley said, this idea was wholly unknown till 1858.Huxley① said the book was like a flash of lightning in the darkness. He wrote:It did the immense service of freeing us from the dilemma - Refuse to accept the Creation hypothesis, and what have you to propose that can be accepted by any cautious reasoner? In 1857 I had no answer ready, and I do not think anyone else hadA year later we reproached* ourselves with dullness for being perplexed* with such an enquiry. My reflection* when I first made myself master of the central idea of the Origin was " How extremely stupid not to have thought of that!"［7］The hypothesis of natural selection may not be a complete explanation, but it led to a greater thing than itself - an acceptance of the theory of organic* evolution, which the years have but confirmed. Yet at first some naturalists joined the opposition. To the many, who were unable to judge the biological evidence, the effect of the theory of evolution seemed incredible as well as devastating*, to run counter to common sense and to overwhelm* all philosophic and religious landmarks. Even educated man, choosing between the Book of Genesis and the Origin of Species, proclaimed* with Disraeli① that he was "on the side of the Angels".［8］Darwin himself took a modest view. While thinking that natural selection was the chief cause of evolution, he did not exclude Lamarck's idea that characters acquired by long use or disuse might be inherited, though no evidence seemed to be forthcoming. But about 1890 Weismann①drew a sharp distinction between the body (or soma) and the germ cells which it contains. Somatic cells can only reproduce cells like themselves, but germ* cells give rise not only to the germ cells of a new individual but to all the many types of cell in his body. Germ cellsdescend from germ cells in a pure line of germ plasm，but somatic cells trace their origin to germ cells. From this point of view, the body of each individual is an unimportant by-product of his parents’ ger m cells. The body dies, leaving no offspring, but the germ plasms show an unbroken continuity. The products of the germ cells are not likely to be affected by changes in the body. So Weismann's doctrine offered an explanation of the apparent noninheritance of acquired characters.［9］The supporters of pure Darwinism came to regard the minute variations as enough to explain natural selection and natural selection enough to explain evolution. But animal breeders and horticulturists* knew that sudden large mutations* occur, especially after crossing, and that new varieties might be established at once. Then in 1900 forgotten work by Mendel①was rediscovered and a new chapter opened.［10］In 1869 Darwin's cousin, Francis Galton①, applied these principles to mental qualities. By searching books of reference, Galton examined the inheritance of ability. For instance, he found that the chance of the son of a judge showing great ability was about 500 times as high as that of a man taken at random, and for the judge's father it was nearly as much. While no prediction can be made about individuals, on the average of large numbers, the inheritance of ability is certain.Ⅰ.

School often has too restricting atmosphere, with its timetable and disciplines, to allow him much time for independent assessment of the work he is asked to do. Most s tudents would, I believe, profit by a year or so’s exploration of different academic studies, especially those “all-rounders” with no particular interest.B.

Unit one你认为自己是什么样的人，那你就是什么样的人如果你改变想法——从悲观变为乐观——你就可以改变自己的生活卡勒普-撒弗兰[ 1 ] 你看酒杯是半杯有酒而不是半杯空着的吗?你的眼睛是盯着炸面圈，而不是它中间的孔吗? 当研究者们自细观察积极思维的作用时，这些陈辞滥调突然问都成了科学问题。
[ 2 ] 迅速增多的大量研究工作——迄今已有104个研究项目，涉及大约15 000人——证明乐观的态度可以使你更快乐、更健康、更成功。
与此相反，悲观则导致无望、疾病以及失败，并与沮丧、孤独及令人苦恼的腼腆密切相关。
位于休斯敦莱斯大学的心理学家克雷格·A·安德森说：“如果我们能够教会人们更积极地思考，那就如同为他们注射了预防这些心理疾病的疫苗。
”[ 3 ]“你的能力固然重要，”匹兹堡的卡内基一梅降大学的心理学家迈克尔·F·沙伊尔说，“但你成功的信念影响到你是否真能成功，”在某种程度上，这是由于乐观者和悲观者以截然不同的方式对待同样的挑战和失望。
[ 4 ] 以你的工作为例。
宾夕法尼亚大学的心理学家马丁·E·P·塞利棉曼与同事彼得·舒尔曼在一项重要研究中对大都市人寿保险公司的推销员进行了广泛调察。
他们发现，存工龄较长的推销员中，积极思考比消极思考者要多推销37％的保险额。
机新雇用的推销员中，乐观主义者则多销了20％。
[ 5 ] 公司受到了触动，便雇用了100名虽未通过标准化企业测试但在态度乐观一项得分很高的人。
这些本来可能根本不会被雇用的人售出的保险额高出推销员的平均额10％。
[ 6 ] 他们是如何做的呢？据塞利格曼说，乐观主义者成功的秘诀就在于他的“解释方式”。
出了问题之后，悲观主义者倾向于自责。
他说：“我不善于做这种事，我总是失败。
”乐观主义者则寻找漏洞，他责怪天气、抱怨电话线路、或者甚至怪罪别人。
他认为，是那个客户当时情绪不好。

研究生英语精读教程（下）答案Unit 2Exercise AI．Comprehension1．The distinction between active and passive euthanasia is clear．In the former case，some direct action is taken(for example，lethal injection is given．) to help finishing the patient’s unbearable pain for good，while in the latter，no direct action is taken，merely letting the patient die．2．The attitude of AMA is somewhat contradictory．First，it states that mercy killing is contrary to what the medical profession stands and also to its own policy．But then it goes on to say that the advice and judgment of the doctor should be available to the patient and／or his family．3．A lethal injection is one which can“kill”the patient immediately．The author thinks that once the decision not to prolong the patient's agony is made，to give him a lethal injection is the best choice．Otherwise the patient will suffer more rather than less．4．The most painful thing to do for a surgeon is to stand by and watch a savable baby die because his very duty is to use the scalpel to fight off death．5．Some people are opposed to all kinds of euthanasia because they believe that all people have the right to live．6．The author believes that the reason to let the baby die is only an excuse．And the real reason is that the child has Down's syndrome because the operation is very simple．7．No，killing someone is not morally worse than letting someone die．(An example is omitted．) 8．What the doctor does in active euthanasia is only for humane reasons．In a civil case of killing，however，the person acts from the motive of personal gain．That's the main difference．9．Mercy killing and conventional euthanasia are the same thing，because in both cases the passive part the doctor plays is emphasized．10．The attitude of AMA in its statement is contradictory．First，it forbids mercy killing, but then it goes on to deny that the cessation of treatment is the intentional termination of life．This is where the mistake is made, for the former is none other than the 1atter．Ⅱ．V ocabulary1．C 2．A 3．A 4．B 5．A6．C 7．C 8．D 9．A 10．D11．B 12．B 13：D 14．D 15．B16．C 17．A 18．D 19．A 20．DⅢ．Cloze1．B 2．A 3．C 4．D 5．C6．A 7．B 8．A 9．C 10．B11．D 12．A 13．B 14．B 15．CⅣ．TranslationA．没有一个年轻人相信他是要死的。
