To inspire young people to take action⑪ for the environment，animals and their community⑫，Roots & Shoots was established.This institute⑬ was set up in the early 1990s⑭ by Dr.Jane Goodall，a scientist who's the world's best­known expert on wild chimpanzees⑮.In addition to⑯ her research，she has been whole­heartedly committed to⑰ environmental protection⑱.The whole purpose of Roots & Shoots is to educate young people，from pre­schoolers⑲ to university students，so they can help to build a future that is secure and live together in peace with nature⑳. The organisation is called Roots & Shoots because roots move slowly under the ground to make a firmeq \o(○,\s\up8(21))foundationeq \o(○,\s\up8(22))，and shoots seem small and weak，but they can break open brickeq \o(○,\s\up8(23)) walls to reach the lighteq \o(○,\s\up8(24)).The roots and shoots are you，your friends and young people all around the worldeq \o(○,\s\up8(25)).Hundreds and thousands of roots and shoots can solve the problems，change the world and make it a better place to live ineq \o(○,\s\up8(26)). Do you think you help to make the world a better place when you make a sad person smile，when you make a dog wageq \o(○,\s\up8(27)) its tail，and when you water a thirsty plant？One cheered­up person，one happy dog，one flowering plant，and you.That's what Roots & Shoots is all abouteq \o(○,\s\up8(28))：the value and importance of each individual—human，animal or plant.Dr.Jane Goodall believes that the most important thing is that：“Every individual matters.eq \o(○,\s\up8(29)) Every individual has a role to play.Every individual makes a differenceeq \o(○,\s\up8(30)).” 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 ineq \o(○,\s\up8(31)) everyone's heart？Do you want to be a part of a community for a shared future？You cannot be absent. It is by acting together，in this exciting way，that we can involveeq \o(○,\s\up8(32)) thousands­millions­of people，and this is what is going to change the world. —Jane Goodall 语料积累 ①root n.树根；根源 vi.& vt.生根；固定 ②shoot n.芽，苗；嫩枝 vi.& vt.射击，射中；拍摄；发芽 ③suffer from 患……病；受……之苦 ④句中what引导宾语从句。 ⑤leave the tap running让水龙头开着 ⑥litter n.垃圾vt.& vi.乱丢 ⑦can't be bothered to do sth懒得做某事 bothered adj.担心的；烦恼的 ⑧so what那又怎样 ⑨本句为if引导的虚拟条件句。 ⑩gallon n.加仑 ⑪take action采取行动 ⑫本处为不定式作目的状语。 ⑬institute n.机构；研究院 ⑭in the early 1990s 在20世纪90年代早期 ⑮本句为who引导的定语从句。 chimpanzee n.黑猩猩 in addition to 除……之外 (还有，也) in addition另外，此外 ⑰be committed to 致力于；委身于 ⑱environmental protection 环境保护 ⑲pre­schooler n.学龄前儿童 ⑳本句为that引导的定语从句。 eq \o(○,\s\up3(21))firm adj.坚实的；稳固的 firmly adv.牢牢地；坚定地 eq \o(○,\s\up3(22))foundation n.基础；地基 eq \o(○,\s\up3(23))brick n.砖，砖块 eq \o(○,\s\up3(24))本句中because引导原因状语从句，and和but连接并列句。 eq \o(○,\s\up3(25))all around the world全世界 eq \o(○,\s\up3(26))make it a better place to live in 让它成为更好的居住地 eq \o(○,\s\up3(27))wag vi.& vt.(狗) 摇 (尾巴) eq \o(○,\s\up3(28))本句为what引导的表语从句。 eq \o(○,\s\up3(29))本句中第一个that引导宾语从句；第二个that引导表语从句。 eq \o(○,\s\up3(30))make a difference 有影响，有关系 eq \o(○,\s\up3(31))be rooted in 植根于 eq \o(○,\s\up3(32))involve vt.参与；包含 课文译文 根与芽 大多数人都患有所谓的“唯我主义”。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。你知道这些都是不对的，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，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，那就无所 谓了。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；掉下数百万块垃圾。而所有的这些将是非常有害的。 为了激励年轻人行动起来保护环境、动物和他们的社区，“根与芽”诞生了。这个组织于20世纪90年代初由珍·古道尔博士创立，在野生黑猩猩研究领域，她是世界上最著名的专家。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。 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。 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·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。 正是通过共同行动，以这种令人兴奋的方式，我们可以让成千上万的人参与进来，这将改变世界。 ——珍·古道尔 Ⅰ.重点单词 ◎核心单词 1．　root　n.树根 2．　shoot　n.芽，苗；嫩枝 vt.射中；射击 3．　bothered　adj.担心的；烦恼的 4．　institute　n.机构；研究院 5．　brick　n.砖，砖块 6．　gallon　n.加仑 7．　chimpanzee　n.黑猩猩 8．　wag　vi.& vt.(狗) 摇 (尾巴) 9．　just­me­ism　n.以自我为中心 ◎拓展单词 10．　bother　vi.& vt.费心；麻烦；烦扰→bothered adj.担心的；烦恼的 11．　firm　adj.坚实的；稳固的→firmly adv.坚定地；牢牢地 12．　found　vt.建立；创立；创办→founder n.创立者→foundation n.基础；地基 13．　involve　vt.参与；包含→involved adj.参与的；投入的→involvement n.参与 Ⅱ.重点短语 1．　suffer from　遭受；患……病；受……之苦 2．　be known as　以……著称 3．　not be bothered to do sth　懒得做某事 4．　so what　那又怎样 5．　take action　采取行动 6．　in addition to　除……之外 7．　be committed to　致力于；委身于 8．　all around the world　全世界 9．　make a difference　有影响，有关系 10．　be rooted in　植根于 Ⅲ.句式语境 1．Most people suffer from　what is known as “Just­me­ism”　. 大多数人都患有所谓的“唯我主义”。 2．Well, say you leave the tap running　while　you brush your teeth... 比方说你刷牙的时候让水哗哗地流…… 3．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? 如果我让一个小水龙头开着，一盏小灯开着，或者在路上丢下一小片垃圾，这又有什么关系呢？ Ⅰ.Skim the text and choose the best answer. 1．What's the main idea of the text?
