Unit13 We are trying to save the earth

Unit 13 We’re trying to save the earth!要点详解1. We’re trying to save the earth!我们正尽力拯救地球！(1) 本句时态为现在进行时，表示现阶段正在做的事情。

现在进行时所表示的动作并不一定在说话人的说话时刻进行，而是在包括说话时刻在内的一段时间当中进行。

例如：George is translating a book now. 乔治现在在翻译一本书。

（说这句话时，乔治不一定正在翻译；但在包括“说话时刻”在内的一段时间当中，乔治是在从事翻译工作。

）(2) try to do 表示“设法或尽力去做某事”，实际上做与不做，视情况而定，而try doing表示“试着做”，即动作真的进行了或正在进行，成败则视结果而定。

例如：He tried to read, but he was too tired to read much.他想设法看书，但太疲倦了，没看多少。

He tried reading, but that could not make him forget his trouble.他试着看书，但这并没使他忘记烦恼。

2. I am like this animal because I am strong and intelligent.我像这种动物，因为我强壮而聪明。

(1) like在本句中做介词，意为“像”，例如：He looks like winning the race.他看来要在比赛中获胜。

She is like her mother.她像她的妈妈。

(2) like做介词时可用very，very much，rather，quite等副词修饰。

例如：You look very much like your father.你与你父亲很相像。

3. Some of the swamps have become polluted。

一些沼泽已被污染了。

Section A ,3a拯救鲨鱼很多人都听说过鱼翅羹。

这道昂贵又著名的菜在中国南方特别流行。

但是每次当你喝鱼翅羹的时候，你是否意识到你杀了一整只鲨鱼？当人们捕捉到鲨鱼的时候，他们切掉鲨鱼的鱼鳍，然后把它们扔回大海。

失去鱼鳍的鲨鱼再也不能再水里游，会慢慢死去。

这种做法不仅残忍，而且对环境有害。

鲨鱼处于海洋生态系统食物链的顶端，如果他们的数量下降得太多，将会给所有的海洋生物带来危害。

很多人认为鲨鱼永远不会濒临灭绝，因为他们是食物链的最强者。

但事实上，每年有七百万的鲨鱼被捕杀和交易。

在过去的20年到30年，某些品种的鲨鱼数量下降了超过90%。

世界各地的环保组织，如野生救援协会和世界自然基金会，都在向公众宣讲“猎翅的（残忍）行为。

他们甚至已经呼吁政府立法停止鱼翅的销售。

到目前为止，没有任何科学研究表明，鱼翅对健康有好处，那么为什么要吃他们呢？帮助拯救鲨鱼吧！Section B , 2a重新思考重新使用，重新利用你经常扔掉你不在使用的东西吗？你是否曾想过这些东西还能很好地重新利用？如果你有一个充满创意的头脑，没有东西是废品。

你可能从来没听说过艾米.海斯，但她是一个非常不寻常的女性。

Section A ,3a拯救鲨鱼很多人都听说过鱼翅羹。

这道昂贵又著名的菜在中国南方特别流行。

但是每次当你喝鱼翅羹的时候，你是否意识到你杀了一整只鲨鱼？当人们捕捉到鲨鱼的时候，他们切掉鲨鱼的鱼鳍，然后把它们扔回大海。

失去鱼鳍的鲨鱼再也不能再水里游，会慢慢死去。

这种做法不仅残忍，而且对环境有害。

鲨鱼处于海洋生态系统食物链的顶端，如果他们的数量下降得太多，将会给所有的海洋生物带来危害。

很多人认为鲨鱼永远不会濒临灭绝，因为他们是食物链的最强者。

但事实上，每年有七百万的鲨鱼被捕杀和交易。

在过去的20年到30年，某些品种的鲨鱼数量下降了超过90%。

世界各地的环保组织，如野生救援协会和世界自然基金会，都在向公众宣讲“猎翅的（残忍）行为。

他们甚至已经呼吁政府立法停止鱼翅的销售。

到目前为止，没有任何科学研究表明，鱼翅对健康有好处，那么为什么要吃他们呢？帮助拯救鲨鱼吧！Section B , 2a重新思考重新使用，重新利用你经常扔掉你不在使用的东西吗？你是否曾想过这些东西还能很好地重新利用？如果你有一个充满创意的头脑，没有东西是废品。
