only silence lay over the fields and woods and marsh. 在清晨曾经有知更鸟、猫鹊、鸽子、松鸦、鹪鹩和许多其他鸟类的声音在合唱，现在却没有了声音；只有寂静笼罩着田野、树林和沼泽。 课前预习自检 ⑥_______ v. 生机勃勃；热闹 ⑦_______ n. 合唱曲 ⑧_______ n. 知更鸟 ⑨_______ n. 猫鹊 ⑩_______ n. 鸽子 ⑪_______ n. 松鸦 ⑫_______ n. 鹪鹩(一种褐色小鸟) ⑬_______ n. 沼泽，湿地 throb chorus robin catbird dove jay wren marsh 课前预习自检 Rachel Carson was a scientist by profession, but these lines from the opening chapter of her 1962 book Silent Spring, “A Fable for Tomorrow”， show her talent as a writer. 蕾切尔·卡森的职业是科学家，但她1962年出版的《寂静的春天》一书中开篇章节“明天的寓言”的这段话显示了她作为作家的才华。 By imagining a world without birds, she aimed to alert not only the scientific community but also the general public to the damaging effects of human activity on natural ecosystems—in particular, to the harmful use of pesticides, such as DDT. 通过想象一个没有鸟类的世界，她不仅是提醒科学界，而且是提醒普通大众，人类活动对自然生态系统的破坏性影响——特别是对DDT等杀虫剂的有害使用。 课前预习自检 She believed that the chemical industry was knowingly causing harm to plants, animals and even humans, and wished to see pesticides used in a more responsible, limited and carefully monitored way. 她认为，化学工业正在有意地对植物、动物甚至人类造成伤害，她希望看到人们以一种更负责任、有限制性的和仔细的监测方式来使用农药。 课前预习自检 ⑭______ n. 寓言 ⑮______ v. 提醒，使(某人)意识到 ⑯__________ adv. 故意地 fable alert knowingly 课前预习自检 Carson urged people to make themselves aware of the facts and do something about the situation. 卡森敦促人们要意识到现实，并对现状采取行动。 Silent Spring contains a lot of scientific research and case studies. 《寂静的春天》包含了大量的科学研究和案例研究。 The book details the gypsy moth eradication programme, which killed birds, in addition to gypsy moths. 这本书详细介绍了舞毒蛾根除计划，该计划杀死了舞毒蛾，还杀死了鸟类。 Another case study was the fire－ant programme that killed cows, but not fire ants. 另一个案例研究是火蚁计划，该计划杀死了奶牛，但没有(杀死)火蚁。 课前预习自检 ⑰ ____________ 舞毒蛾 gypsy moth 课前预习自检 •The book also gives dozens of other examples of eradication programmes that did nothing to reduce the problems they were originally designed to solve. 这本书还列举了许多其他根除计划的例子，这些例子都对最初用来解决的问题毫无帮助。 •The 50 or so pages at the end of the book list Carson's sources, showing how thorough and precise she was as a scientist. 在书的最后五十几页列出了卡森的资料来源，显示出她是一位多么严谨细致的科学家。 课前预习自检 ⑱_______ number 一打；许多 ⑲________ adj. 仔细的；缜密的 ⑳________ adj. 精确的；一丝不苟的 21 “主(The book)谓(gives)宾(dozens of other examples of eradication programmes)”。that did nothing to reduce the problems是_______从句，修饰先行词programmes;

half a century later it remains a book that deserves to be reread today, so that we can once again feel ourselves warm to the fire of its passionate message. 她的书不仅改变了(当时的)世界，在半个世纪后的今天，它仍然是一本值得我们重读的书，所以我们还能感受到它热情的文字所传递的温暖。 •For unless we do listen to Rachel Carson's warning, one day we may wake up to the strange and quiet horror of another silent spring. 因为，除非我们真的听从蕾切尔·卡森的劝告，否则总有一天我们可能在另一个奇怪而又相当恐怖的寂静的春天中醒来。 课前预习自检 30 __________ adj. 具有强烈信念的 31 “__________从句(unless ... warning)＋主句(one ... spring)”。主句的结构为“主(we)谓(may wake up) _____(to the strange and quiet horror of another silent spring)”。 passionate 条件状语 状 课前预习自检 重点合作探究 1 ban v. 禁止，取缔(教材P90) 归纳 拓展 情景 助记 重点合作探究 ①They banned visitors from smoking in the building. 他们禁止来访者在大楼内吸烟。 ②There is a ban on smoking in the public places. 在公众场合有不吸烟的禁令。 ③The government has put/placed a ban on the import of ivory. 政府禁止象牙进口。 ban的同义词是：forbid, prohibit。 重点合作探究 (1)单句语法填空 ①Do you think smoking should _________ (ban)? ②Officials have been banned _______ drinking at lunchtime.

Michalis Vousdoukas, of the European Union's Joint Research Center in Ispra, Italy, was the lead researcher. “Tourist areas which have sandy beaches as their main selling point will probably face strong consequences.” he said. Aside from economic value, beaches play an important environmental role. “Sandy beaches are important habitats supporting a wide range of species. They also protect the coast from the effects of storms, so without sandy beaches other inland environments can be affected by the effects of waves and saltwater entering，” Vousdoukas added. 课后课时作业 63 The main causes are rising sea­level and erosion (侵蚀) from storms, the study says, which warned of the near­disappearance of almost half of the world's sandy beaches by the end of the century. Beaches in the United States will be “greatly affected”， as will shorelines in Canada, Mexico, China and Chile. In the US, beaches along the East Coast and the Gulf Coast will experience the most erosion. 课后课时作业 64 Michalis Vousdoukas and other researchers used satellite images to track the way beaches have changed over the past 30 years and patterned how global warming might affect them in the future. They found that West Africa will see some of the worst losses, where more than 60% of sandy coastline may be lost in countries such as The Gambia and Guinea­Bissau. Australia will also take a hit: when the total length of sandy beach projected to be lost is analyzed, Australia would be hit the hardest, with more than 7，000 miles at risk. 篇章导读：本文是一篇说明文。文章介绍了到2100年将会有一半的沙滩消失，并提醒人们保护环境。 篇章导读 课后课时作业 65 解析：细节理解题。根据第二段中的“Sandy beaches are important habitats ... of species.”可知，沙滩为各种各样的物种提供栖息地，所以很重要。故选A。 答案 解析 1．Why are beaches important to wildlife?

A．Over population and more tourism. B．Severe erosion and coastline losses. C．Sea­level rise and storm destruction. D．Global warming and climate change. 课后课时作业 67 解析：细节理解题。根据最后一段中的“They found that ... such as The Gambia and Guinea­Bissau.(他们发现，西非将出现一些损失最严重的地区，冈比亚和几内亚比绍等国可能会损失60%以上的沙质海岸线。)”可知，冈比亚一半以上的海岸线可能会消失。故选C。 答案 解析 3．Which country possibly loses more than half of sandy coastline according to the study? A．Chile. B．Australia. C．The Gambia. D．The United States. 课后课时作业 68 解析：推理判断题。通读全文，尤其根据第一段内容可推知，作者写本文的主要目的是引起人们对沙滩逐渐消失这一问题的关注，呼吁人们共同保护环境。故选B。 答案 解析 4．What is the author's purpose in writing this text?
