必修第三册 UNIT 8　GREEN LIVING Period 2　Lesson 1　Roots and Shoots—Reading Comprehension　 Roots & Shoots Most people suffer from what is known as “Just-me-ism①”. What is that? Well, say you leave the tap② running while you brush your teeth, leave a light on when you go out or you drop a piece of litter and can’t be bothered③ to pick it up. You know that all those things are wrong, but so what? “What difference can it possibly make？” you say to yourself.“There are millions of people in the Part 1　教材原文助读 world and I’m just me. How can it matter if I leave one little tap running, one little light on or leave a little piece of litter on the road? And anyway, no one will know.” Of course, it wouldn’t matter if there were just a few people in the world. But just think of all the millions of people saying to themselves: “It doesn’t matter. It’s just me.And, anyway, no one knows.” Millions of gallons④ of water would be wasted; millions of lights would be left on; millions of pieces of litter would be dropped. And all of this would be very harmful⑤. 本句使用了虚拟语气，表示与将来事实相反的假设。这里假设的条件没有通过条件状语从句表达出来，而是隐含在上文中。 ①just-me-ism /dʒəst'miːIzəm/ n．以自我为中心，自我中心主义 ②tap /tæp/ n．龙头；阀门 ③bother /'bɒðə/ vi.& vt.费心，麻烦 can’t be bothered to do sth.懒得做某事 ④gallon /'ɡælən/ n．加仑 ⑤harmful adj.(尤指对健康或环境)有害的，导致损害的 根与芽 很多人都有所谓的“就我一个”问题。这是什么意思呢？比方说你刷牙的时候让水哗哗地流，外出的时候不关灯，或者掉了一块垃圾却懒得捡起来。你知道这些都是错的，但那又怎么样？“会有什么差别呢？”你对自己说，“世界上有数百万人，我不过是我自己。如果我不关一个小小的水龙头，开着一盏小小的灯或在路上掉了一小块垃圾，这会有什么问题？而且不管怎样， 也没人会知道。”当然，如果世界上只有几个人这样，那也没关系。但试想要是数百万人都对自己说：“没关系，只有我一个。而且，不管怎样，也没人会知道。”那将会浪费数百万加仑的水，忘记关掉数百万的灯，掉下数百万块的垃圾。而这些都是非常有害的。 To inspire young people to take action⑥ for the environment, animals and their community, Roots & Shoots was established. This institute⑦ was set up⑧ in the early 1990s by Dr. Jane Goodall, a scientist who’s the world’s best-known expert on wild chimpanzees⑨. In addition to⑩ her research, she has been whole-heartedly committed to⑪ environmental protection. The whole purpose of Roots & Shoots is to educate young people, from pre-schoolers to university students, so they can help to build a future that is secure⑫ and live together in peace with⑬ nature. 本句为so连接的并列复合句。第一个分句中，不定式短语to educate...students作表语；第二个分句中，定语从句that is secure...with nature修饰先行词a future。 ⑥take action采取行动 ⑦institute /'InstItjuːt/ n．机构；研究院 ⑧set up设置；创建；建立；开办； 引发；产生 ⑨chimpanzee /ˌtʃImpæn'ziː/ n．黑猩猩 ⑩in addition to除……以外(还) ⑪commit to sb./sth. 忠于(某个人、机构等)；全心全意投入(工作、活动等) ⑫secure adj.安全的；稳当的；有把握的 a secure job/income稳定的工作/收入 ⑬in peace with与……和平相处 为了激励年轻人行动起来保护环境、动物和社区，“根与芽”组织成立了。这个研究所是由世界上最著名的野生黑猩猩专家珍妮·古道尔博士在20世纪90年代初建立的。除了自己的科研，她还全身心地投入环保事业。“根与芽” 的目的是教育年轻人，从学龄前儿童到大学生，使他们能够为创造一个安全、与自然和平共处的未来而贡献力量。 The organisation is called Roots & Shoots because roots⑭ move slowly under the ground to make a firm⑮ foundation⑯， and shoots⑰ seem small and weak, but they can break open brick⑱ walls to reach the light. The roots and shoots are you, your friends and young people all around the world⑲. Hundreds and thousands of roots and shoots can solve the problems, change the world and make it a better place to live in. ⑭root /ruːt/ n．树根 ⑮firm /fɜːm/ adj.实的；稳固的 ⑯foundation/faʊn'deIʃən/ n．基础；地基 ⑰shoot /ʃuːt/ n．芽，苗；嫩枝 vt.射中；射击 ⑱brick /brIk/ n．砖，砖块 ⑲all around the world全世界 这个组织取名“根与芽”，取意根部在地下缓慢延伸以形成坚实的基础，而芽看起来又小又弱，却可以向着光明冲破砖墙的阻挡。根和芽就是你、你的朋友和世界各地的年轻人。成千上万的根和芽能够解决问题，改变世界，使其更加宜居。 Do you think you help to make the world a better place when you make a sad person smile, when you make a dog wag⑳ its tail, and when you water a thirsty plant？ One cheered-up person, one happy dog, one flowering plant, and you. That’s what Roots & Shoots is all about: the value and importance of each individual—human, animal or plant. Dr. Jane Goodall believes that the most important thing is that: “Every individual matters㉑. Every individual has a role to play㉒. Every individual makes a difference㉓.” You get to choose: Do you want to use your life to make the world a better place for people, animals and the environment? Do you want to make Roots & Shoots rooted in everyone’s heart? Do you want to be a part of㉔ a community for a shared future? You cannot be absent. 本句中含有三个when引导的时间状语从句，并包含了三个“make＋宾语＋宾语补足语”结构。 ⑳wag /wæɡ/ vi.& vt.(狗)摇(尾巴) ㉑matter vi.事关紧要；要紧；有重大影响 As long as you’re happy, that’s all that matters.只要你幸福，这就是最重要的事情。 ㉒have a role to play扮演一个角色；发挥作用 ㉓make a difference有影响； 起(重要)作用 ㉔be (a) part of...成为……的一员；成为……的一部分 当你使一个悲伤的人破涕为笑，让一只狗摇尾巴， 给一株干渴的植物浇水时，你觉得自己让世界变得更美好了吗？一个振作起来的人，一只快乐的狗，一株开花的植物和你。这就是“根与芽”的全部意义：重视每一个个体的价值和重要性，不管是人、 动物还是植物。珍妮·古道尔博士认为，最重要的是：“每一个个体都很重要。每一个个体都有自己的角色。每一个个体都能有所作为。”你可以选择：你想通过自己的生活，为了人类、动物和环境而让世界变得更美好吗？你想让“根与芽”植根于每个人的心中吗？你想成为命运共同体的一员吗？你不能缺席。 It is by acting together, in this exciting way, that we can involve㉕ thousands—millions—of people, and this is what is going to change the world. 本句为and连接的并列句。第一个分句使用了强调句型，强调方式状语；第二个分句中含有what引导的表语从句，what在从句中作主语。 —Jane Goodall ㉕involve /In'vɒlv/ vt.参与；包含 正是通过这种令人激动的方式共同行动起来，我们可以让数千甚至数百万人参与其中，这将改变世界。 ——珍妮·古道尔 1．Match the main ideas with the paragraphs.

On November 7, 2003, researchers attached an electronic tracker to her fin (鳍) while she was in the waters of South Africa.After completing the first leg of the journey, the tag (标签) fell off near Exmouth Gulf in Western Australia and sent the data to the satellite. It showed that she had swum from South Africa to Australia, around 11，100 kilometers, in just 99 days—a record-breaking achievement. The researchers thought this would be the end of the story, but she was spotted again on August 20, 2004—all the way back in South Africa. “This is one of the most significant discoveries about white sharks and suggests that we might have to rewrite the life history of this powerful fish，” Dr.Ramón Bonfil said.“More importantly, Nicole has shown us that separate populations of great white sharks may be more directly connected than previously thought, and that wide-ranging white sharks that are nationally protected in places such as South Africa and Australia are much easier to be hurt by human fishing in the open oceans than we previously thought.” Great white sharks are some of the world’s toughest travelers, which are regularly seen crossing extreme routes around the world’s oceans.They don’t gently wander on their voyages either；the species can complete some of the fastest transoceanic migrations ever seen by sea animals.While most of the journey was made at the ocean’s surface, Nicole regularly jumped into the Indian Ocean basin (盆地) at a depth of 980 meters.In 2005, this was a record breaker for great whites, but scientists have since found they can swim as deep as 1，128 meters. [语篇解读]　本文是一篇说明文。文章主要说明了大白鲨Nicole从南非游到澳大利亚再返回的迁徙历程，其中第一阶段创下了海洋动物跨洋回迁的最快纪录。通过收集相关数据，科学家们对大白鲨的生活史有了新的认识。 1．What was unique about Nicole’s journey to Australia? A．It was the longest journey by a shark. B．She was the first shark tagged electronically. C．It was the fastest recorded transoceanic trip. D．It took her less than 100 days to complete. 答案：D 2 3 1 4 解析：细节理解题。根据第三段中的“It showed that she had swum from South Africa to Australia, around 11，100 kilometers, in just 99 days—a record-breaking achievement.”可知，Nicole的澳大利亚之旅花了不到100天的时间完成。故选D。 2 3 1 4 2．What can we learn from Dr.Bonfil’s research? A．Populations of white sharks are completely alone. B．White sharks have no significant interconnections. C．White sharks have closer connections than thought. D．Human fishing has fewer influences on sharks. 答案：C 2 3 1 4 解析：细节理解题。根据倒数第二段中的“More importantly, Nicole has shown us that separate populations of great white sharks may be more directly connected than previously thought”可知，白鲨种群之间的联系比我们想象的要紧密。故选C。 2 3 1 4 3．What does Nicole’s deep swimming behavior suggest? A．Great whites prefer deeper waters. B．Great whites hunt in deep ocean basins. C．All great whites jump into similar depths. D．Great whites can survive extreme pressures. 答案：D 2 3 1 4 解析：推理判断题。根据最后一段中的“While most of the journey was made at the ocean’s surface, Nicole regularly jumped into the Indian Ocean basin at a depth of 980 meters.In 2005, this was a record breaker for great whites, but scientists have since found they can swim as deep as 1，128 meters.”可知，Nicole的深海游泳行为说明了大白鲨能在极端压力下生存。故选D。 2 3 1 4 4．In which section of a newspaper may the text appear? A．Nature.　　　　　　　 B．Technology. C．Entertainment. D．Education. 答案：A 2 3 1 4 解析：文章出处题。本文介绍的是Nicole的越洋旅行展示了大白鲨种群间可能的联系，并揭示了它们在国际水域面临的危险。由此可知，本文与自然有关。故选A。 2 3 1 4 B Austrian biologist Johannes Fritz has devoted his career to helping northern bald ibises (鹮), also called waldrapp.This rare species of bird was completely extinct in the wild 50 years ago.However, through careful reintroduction, he’s been able to “rewild” 277 ibises in his home country.To ensure that they survive the temperatures of the winter, Fritz even taught young birds a new migration (迁徙) path from Austria to Italy with the help of a flying machine. Fritz guided the first group of ibises in 2004.However, that path has already been affected by climate change. After noticing that the first group of ibises failed to make the trip, he and his team at Waldrapp Team captured the birds and drove them where they needed to go. This was only a temporary solution, of course. Soon afterward, Fritz was designing a new route for the ibises which would help them avoid the dangers of the Alps. Using a special three-wheeled vehicle, Fritz took off with the birds. He taught them a new migration path measuring about 2，500 miles, which is about three times longer than the old route. Rather than go to Italy, the ibises now travel to Spain’s southern Atlantic coast. It takes Fritz and the birds six weeks to make a one-way trip. Some may wonder how Fritz is able to teach the birds in his flying machine, and why the ibises choose to follow him.The answer is quite simple.Fritz and the Waldrapp Team have taken good care of the birds, feeding them and supporting them.So they willingly follow him in these training sessions, despite not knowing their new destination. [语篇解读]　本文是一篇说明文。文章主要讲述了Fritz重新引入隐鹮，教它们新的迁徙路线的故事。 5．What do we know about northern bald ibises? A．They are common after reintroducing. B．They always migrate from Austria to Italy. C．They were saved by Fritz. D．They died out in the wild 50 years ago. 答案：D 5 6 7 8 解析：细节理解题。根据第一段中的“Austrian biologist Johannes Fritz has devoted his career to helping northern bald ibises , also called waldrapp.This rare species of bird was completely extinct in the wild 50 years ago.”可知，隐鹮在50年前就在野外灭绝了。故选D项。 5 6 7 8 6．What does the underlined word “captured” in paragraph 2 mean? A．Caught. B．Fed. C．Set free. D．Warmed up. 答案：A 5 6 7 8 解析：词义猜测题。根据画线词所在句上文“After noticing that the first group of ibises failed to make the trip”以及下文“and drove them where they needed to go”可知，在看到第一组隐鹮未能成功飞行后，隐鹮小队要把它们驱赶到它们需要去的地方，从而推知，画线词应为“捕捉，捕获”的意思，与A项同义。故选A项。 5 6 7 8 7．How many miles does the old migration route measure probably? A．7，500. B．625. C．833. D．2，500. 答案：C 5 6 7 8 解析：细节理解题。根据第三段中的“He taught them a new migration path measuring about 2，500 miles, which is about three times longer than the old route.”可知，旧的迁徙路线大约长2 500÷3≈833英里。故选C项。 5 6 7 8 8．Why do ibises accept help from Fritz? A．They are aware of their destination. B．They are kind and simple. C．They are looked after by Fritz. D．They are forced to do that. 答案：C 5 6 7 8 解析：推理判断题。根据最后一段的内容可知，隐鹮会接受Fritz的帮助的原因是它们被Fritz照顾得很好。故选C项。 5 6 7 8 $$
