❖ DESCRIPTION OF ACCOMPLISHMENTS: After completing her education, Carson joined the U. S. Bureau of Fisheries as the writer of a radio show entitled "Romance Under the Waters," in which she was able to explore life under the seas and bring it to listeners. In 1936, after being the first woman to take and pass the civil service test, the Bureau of Fisheries hired her as a full-time junior biologist, and over the next 15 years, she rose in the ranks until she was the chief editor of all publications for the U.S. Fish and Wildlife Service.
《寂静的春天》(Silent Spring)-文档资料
《寂静的春天》（Silent Spring）《寂静的春天》（SilentSpring）于1972～1977年间陆续译为中文，开首的几章曾在中国科学院地球化学研究所编辑出版的学术刊物“环境地质与健康”上登载过，全书于1979年由科学出版社正式出版。
20年后的今天，我们高兴地看到，在中国社会科学院哲学研究所吴国盛先生及吉林人民出版社的协同努力下，这本书得以纳入《绿色经典文库》再版。
我们衷心希望，这本彪炳史册的著作为中国环境保护事业带来的启迪和推动，能够继续下去。
《寂静的春天》1962年在美国问世时，是一本很有争议的书。
它那惊世骇俗的关于农药危害人类环境的预言，不仅受到与之利害悠关的生产与经济部门的猛烈抨击，而且也强烈震撼了社会广大民众。
你若有心去翻阅本世纪60年代以前的报纸或书刊，你将会发现几乎找不到“环境保护”这个词。
这就是说，环境保护在那时并不是一个存在于社会意识和科学讨论中的概念。
确实，回想一下长期流行于全世界的口号——“向大自然宣战”、“征服大自然”，在这儿，大自然仅仅是人们征服与控制的对象，而非保护并与之和谐相处的对象。
人类的这种意识大概起源于洪荒的原始年月，一直持续到20世纪。
没有人怀疑它的正确性，因为人类文明的许多进展是基于此意识而获得的，人类当前的许多经济与社会发展计划也是基于此意识而制定的。
蕾切尔．卡逊(RachelCarson)第一次对这一人类意识的绝对正确性提出了质疑。
这位瘦弱、身患癌症的女学者，她是否知道她是在向人类的基本意识和几千年的社会传统挑战?《寂静的春天》出版两年之后，她心力交瘁，与世长辞。
作为一个学者与作家，卡逊所遭受的诋毁和攻击是空前的，但她所坚持的思想终于为人类环境意识的启蒙点燃了一盏明亮的灯。
蕾切尔．卡逊1907年5月27日生于宾夕法尼亚州泉溪镇，并在那儿度过童年。
她1935年至1952年间供职于美国联邦政府所属的鱼类及野生生物调查所，这使她有机会接触到许多环境问题。

C. Big tradition and small tradition
An idea particularly important in the study of cultural anthropology.
✓ History is not a series of events that have a linear, causal relationship.
✓ The self-claimed objective analysis is impossible.
✓ Traditional historians ask, “What happened?” and “What does the event tell us about history?” New historicists ask, “How has the event been interpreted?” and “What do the interpretations tell us about the interpreters?”

Quotes from Rachel Carson
It is the public that is being asked to assume the risks that the insect controllers calculate. The public must decide whether it wishes to continue on the present road, and it can do so only when in full possession of the facts. We still talk in terms of conquest. We still haven't become mature enough to think of ourselves as only a tiny part of a vast and incredible universe. Man's attitude toward nature is today critically important simply because we have now acquired a fateful power to alter and destroy nature.

settlers moved during the 19th century to establish new farms and new cities. In films it is often shown as a place where cowboys and Native Americans fight each other, and where cowboys use guns rather than law to settle arguments. Therefore, a situation where there are no laws or controls is sometimes described as being like the Wild West.

Oral Work
Pesticides are not publicly dangerous. The major claims of Miss Rachel Carson's book, “Silent Spring”, are gross distortions of the actual facts, completely unsupported by scientific, experimental evidence, and general practical experience in the field. Her suggestion that pesticides are in fact biocides destroying all life is obviously absurd in the light of the fact that without selective biologicals these compounds would be completely useless.

精读-silent-spring-原文-寂静的春天(同飞君)
There was once a town in the heart of America where all life seemed to live in harmony with its surroundings. The town lay in the midst of a checkerboard of prosperous farms, with fields of grain and hillsides of orchards where, in spring, white clouds of bloom drifted above the green fields. In autumn, oak and maple and birch set up a blaze of colour that flamed and flickered across a backdrop of pines. Then foxes barked in the hills and deer silently crossed the fields, half hidden in the mists of the autumn mornings.Along the roads, laurel, viburnum and alder, great ferns and wild flowers, delighted the traveller's eye through much of the year. Even in winter the roadsides were places of beauty, where countless birds came to feed on the berries and on the seed heads of the dried weeds rising above the snow. The countryside was, in fact, famous for the abundance and variety of its bird life, and when the flood of migrants was pouring through in spring and autumn people travelled from great distances to observe them. Others came to fish the streams, which flowed clear and cold out of the hills and contained shady pools where trout lay. So it had been from the days many years ago when the first settlers raised their houses, sank their wells and built their barns.Then a strange blight crept over the area and everything began to change. Some evil spell had settled on the community: mysterious maladies swept the flocks of chickens; the cattle and sheep sickened and died. Everywhere was a shadow of death. The farmers spoke of much illness among their families. In the town the doctors had become more and more puzzled by new kinds of sickness appearing among their patients. There had been several sudden and unexplained deaths not only among adults but even among children, who would be stricken suddenly while at play and die within a few hours.There was a strange stillness. The birds, for example — where had they gone Many people spoke of them, puzzled and disturbed. The feeding stations in the backyards were deserted. The few birds seen anywhere were moribund; they trembled violently and could not fly. It was a spring without voices. On the mornings that had once throbbed with the dawn chorus of robins, catbirds, doves, jays, wrens, and scores of other bird voices there was now no sound; only silence lay over the fields and woods and marsh.On the farms the hens brooded, but no chicks were hatched. The farmers complained that they were unable to raise any pigs — the litters were small and the young survived only a few days. The apple trees were coming into bloom but no bees droned among the blossoms, so there was no pollination and there would be no fruit.The roadsides, once so attractive, were now lined with browned and withered vegetation as thoughswept by fire. These too, were silent, deserted by all living things. Even the streams were now lifeless. Anglers no longer visited them, for all the fish had died.In the gutters under the eaves and between the shingles of the roofs, white granular powder still showed a few patches; some weeks before it had fallen like snow upon the roofs and the lawns, the fields and streams.No witchcraft, no enemy action had silenced the rebirth of new life in this stricken world. The people had done it themselves.This town does not actually exist, but it might easily have a thousand counterparts in America or elsewhere in the world. I know of no community that has experienced all the misfortunes I describe. Yet every one of these disasters has actually happened somewhere, and many real communities have already suffered a substantial number of them. A grim spectre has crept upon us almost unnoticed, and this imagined tragedy may easily become a stark reality we all shall know.What has already silenced the voices of spring in countless towns in America This book is an attempt to explain.Form Silent Spring by Rachel Carson高中/大学组题型解析与赛前准备2014-12-18连云港组委会希望之星英语大赛连云港赛区2015年中央电视台希望之星英语风采大赛【高中/大学组题型解析】A：Hey！This is me. （自我介绍）个性化自我介绍不得超过90秒，出声计时开始。

11. Chemicals sprayed on croplands or forests or gardens lie long in soil, entering into living organisms, passing from one to another in a chain of poisoning and death.(--11) lie long in soil: they stay in soil for a long time because they don’t break down chemically there entering into living organisms, passing from one to another in a chain of poisoning and death: the chemicals that insecticides contain are likely to enter birds and animals in food, and then pass out in waste matter from their bodies, get into the soil and are absorbed by the plants that grow on it. When birds and animals and people eat the plants, these substances again are taken into their bodies. This process goes on and on endlessly, poisoning plant and animal life alike. In short, the chemicals tend to be endlessly recycled in the food chains.
Lesson 11 silent spring
Quotes from Rachel Carson
But man is a part of nature, and his war against nature is inevitably a war against himself. The rains have become an instrument to bring down from the atmosphere the deadly products of atomic explosions. Water, which is probably our most important natural resource, is now used and re-used with incredible recklessness. Now, I truly believe, that we in this generation, must come to terms with nature, and I think we’re challenged as mankind has never been challenged before to prove our maturity and our mastery, not of nature, but of ourselves.
Silent Spring
Summary of the book The book starts with a fable of a lovely rural town that suddenly suffers blight, sickness, and death. Its people finally realize they had poisoned themselves. She presented scientific evidence that this was happening all over the country. She explained in plain terms how the strongest bugs survive, making stronger pesticides necessary, and that DDT, though scarce in the water, becomes concentrated as it works its way up the food chain. She advocated integrated management: using a minimum of chemicals combined with biological and cultural controls.
