你这段文字有很多错误,可能是打的时候打错了吧!有些不合逻辑,我是按照我认为合理的讲法来翻译的.
1.1939年研制的DDT(敌敌畏）是世界上有史以来威力最强的杀虫剂.1940年至1950年间它被广泛用以清除疟疾的携带者——蚊子.它的发明者被授予诺贝尔奖.当它可被用于商业行销,喷酒到农作物上时,很少有人象雷切尔.卡森一样认为它危险.当她的书《寂静的春天》发表后,她的担忧受到广泛关注.《寂静的春天》的影响是巨大的.雷切尔.卡森以这本书为现代环境保护运动奠定了根基.
2.卡森原先并无意去写一本关于DDT的危害的书.一位老朋友的来信激起了她对于这一主题的兴趣,信中说空中喷洒的农药已经破坏了当地的生态系统.仅管雷切尔.卡森是一名畅销书作者,但没有一家杂志社愿意登载她关于研究DDT负面效应的文章.她决定开始写一本相关话题的书《寂静的春天》,这本书耗用了她四年时间才得以完成.这本书描述了DDT如何渗入到食物链,如何在动物包括人类的肌体组织中聚积,如何造成癌症和细胞损伤.这本书最著名的章节“明日寓言”描述了一座不知名的美国小镇,小镇中的一切生命：从鱼到鸟到苹果花果到孩子们都因DDT潜在的影响而沉寂.
3.这本书最先于1962年6月在纽约人杂志上连载刊登,为全国各地的读者们敲响了警钟,不足为怪,也引来了化工业愤怒的叫骂声.美国的一家氰胺制品公司的主管报怨道“如果人们真的听从卡森小姐的教导去做,我们将回到黑暗年代,昆虫和疾病也将再一次占领地球”.其中一些攻击更近乎个人行为,质疑卡森是否诚实,质疑她头脑是否健全.
