Silent SpringThere was a strange stillness①．The birds，fr example—where had they gne？Many peple spke f②them，[1]puzzled③and disturbed．The feeding statins④in the backyards⑤were deserted⑥．The few birds [2]seen anywhere were mribund⑦；they trembled⑧vilently⑨and culd nt fly．It was a spring withut vices．On the mrnings [3]that had nce thrbbed⑩with the dawn chrus⑪f rbins，catbirds，dves，jays，wrens，and scres f⑫ther bird vices there was nw n sund；nly silence lay ver the fields and wds and marsh⑬．
[1]形容词短语作状语，表示主语的状态。[2]过去分词短语作后置定语，修饰birds。[3]关系词that引导的定语从句，修饰先行词mrnings。
Rachel Carsn was a scientist by prfessin⑭，but these lines frm the pening chapter f her 1962 bk Silent Spring，“A Fable⑮fr Tmrrw”，shw her talent as a writer．[4]By imagining a wrld withut birds，she aimed t⑯alert⑰nt nly the scientific cmmunity⑱but als the general public⑲t the damaging effects f human activity n natural ecsystems—in particular，t the harmful use f pesticides，such as DDT．She believed that the chemical industry was knwingly⑳causing harm t㉑plants，animals and even humans，and wished t [5]see pesticides used in a mre respnsible，limited and carefully mnitred㉒ way．
[4]该句是较长的简单句。by 是方式状语；nt als...连接并列的宾语。[5]“see＋宾语＋宾语补足语”结构，过去分词短语used 作宾语补足语；过去分词mnitred作定语修饰way。
Carsn urged peple t㉓make themselves aware f the facts and d smething abut the situatin．Silent Spring cntains a lt f scientific research and case studies．The bk details㉔the gypsy mth eradicatin prgramme，which killed birds，in additin t gypsy mths．Anther case study was the fire-ant prgramme that killed cws，but nt fire ants．The bk als gives dzens f㉕ther examples f eradicatin prgrammes that did nthing t reduce the prblems they were riginally designed t slve．The 50 r s pages at the end f the bk list Carsn's surces，[6]shwing hw thrugh㉖and precise㉗she was as a scientist．[6]动词-ing形式短语作状语，其中hw 为hw引导的宾语从句。
Carsn's message was very alarming㉘，[7]causing a great increase in envirnmental awareness㉙．Its impact was immediate and far-reaching㉚：the use f DDT was banned and the Envirnmental Prtectin Agency (EPA) was established in the US．Silent Spring was therefre regarded as a milestne㉛in the launch㉜f the green mvement in the Western wrld．It als earned Carsn a psthumus㉝Presidential Medal f Freedm and put her face n the 17-cent US stamp．[7]动词-ing形式短语作结果状语。
Silent Spring was nt，hwever，received㉞psitively㉟by everyne．[8]Thugh Carsn's research was strng㊱and was supprted by mst scientists wh reviewed her wrk，the bk quickly became a target fr㊲critics in the pesticide industry．They said that Carsn did nt understand the science behind her arguments because she was a marine bilgist㊳rather than a chemist．Sme als said that her wrk was mre emtinal than scientific．These were attempts t damage
Carsn's reputatin㊴and stp her wrk frm influencing public plicy，but she remained determined t stand by㊵her research．Carsn appeared in public and n televisin t defend her claims㊶—and tday，[9]mre than 50 years after it was published，the vice f Silent Spring is still ringing㊷[10]lud and clear．
[8]thugh引导的让步状语从句，从句中又包含一个wh引导的定语从句。[9]此处为插入语，修饰tday。[10]此处意为“掷地有声，深远绵长”。
Persnally，I enjy Carsn's bk．She [11]made a crucial but ptentially difficult-t-understand㊸subject interesting and accessible t millins f peple．This is nt s much because f the quality f her arguments，[12]strng thugh they are，but because f the beauty and elegance ㊹f her writing．Her bk nt nly changed the wrld；half a century later it remains a bk that deserves t be reread㊺tday，[13]s that we can nce again feel urselves warm t the fire f its passinate㊻message．[14]Fr unless we d listen t Rachel Carsn's warning，ne day we may wake up t㊼the strange and quiet hrrr f anther silent spring．
[11]“make＋宾语＋宾语补足语”结构，此处为形容词短语作宾语补足语。[12]thugh引导的让步状语从句，此处使用了部分倒装语序。[13]s that引导的结果状语从句。[14]此处fr作并列连词，表示因果关系；unless引导条件状语从句，从句中谓语用“d＋动词原形”的形式表示强调。
寂静的春天“一片古怪的寂静笼罩着这里。小鸟都飞到哪里去了？许多人谈论着，茫然困惑、惴惴不安。后院的饲养站已经被遗弃，为数不多的几只鸟也奄奄一息；它们浑身打战，无法飞翔。这是一个寂静的春天。原本喧闹的清晨，再也没有了知更鸟、北美猫鸟、鸽子、松鸦、鹪鹩的奏鸣曲以及其他小鸟的鸣叫声；只留下一片寂静，笼罩在田野、树林和沼泽的上空。”
蕾切尔·卡森本是一位科学家，但是1962 年，她在《寂静的春天》一书的开篇章节“明天的寓言”中的这段描写，展现了她作为作家的天赋。通过想象一个没有鸟类的世界，她想要警告科学界，提醒公众，人类活动已经对自然生态系统造成了破坏性的后果，尤其是使用DDT之类的杀虫剂给自然界带来了严重的危害。她认为化学工业正在明目张胆地对动植物，甚至对人类本身造成伤害，她希望人们在使用杀虫剂时能够更加负责、节制，并且严加监管。
卡森敦促人们认清事实，并且为此做出努力。《寂静的春天》中含有大量的科学研究和真实案例。在灭除舞毒蛾项目这一案例中，她细致讲述了人们在消灭舞毒蛾的同时，也杀死了鸟类；另一个案例则是在开展消灭火蚁计划时，人们杀死的是奶牛，而非火蚁。书中还讲了几十个其他灭除计划的案例，都未能像预期那样解决问题。这本书最后的五十几页列出了卡森的资料来源，显示出她作为一名科学家的周密和严谨。
卡森所述的事实让人们十分担忧，大大提升了人们保护环境的意识。这本书的效果立竿见影，并且影响深远：DDT被禁用，环境保护署也在美国成立。《寂静的春天》因此被视为西方发起绿色运动的里程碑，这使作者在去世后获得了“总统自由勋章”的荣誉，美国17美分的邮票上也印上了她的头像。
但并不是所有人都支持《寂静的春天》。虽然卡森的研究很有说服力，而且得到多数审阅过这本书的科学家的支持，但是这本书很快成了杀虫剂行业批判的对象。他们说卡森并不理解她论证背后的科学原理，因为她是一位海洋生物学家，而非化学家。还有一些人说她的作品过于情感化，科学性并不强。他们想要通过破坏卡森的名声来削减她的作品对公共政策的影响，但卡森仍然坚持自己的研究，在公众面前、在电视节目中捍卫自己的观点。时至今日，《寂静的春天》已经出版五十多年了，但它的影响力依旧深远绵长。
而我个人也十分喜欢卡森的书。她把一个至关重要但十分复杂的问题用简单有趣的方式传达给了数百万人。这并不都是因为她书中高质量的论点是多么强有力，而是因为她美丽和高雅的文笔让读者喜欢。她的书不仅在当时改变了世界，就是在半个世纪后的今天，它仍然值得人们重新阅读，以感受她充满感情的文字带给我们如火焰般的温暖。因为如果我们不听从卡森的劝告，可能有一天在我们醒来之后，真的会面对一个古怪而又相当恐怖的寂静的春天。
