Unit 15 We are trying to save the manatees
新人教版九年级英语下册Unit 13 We’re trying to save the earth!要点详解
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。

5. I have visited a lot of zoos in my life, and I have never seen one I liked or one thatwas suitable for animals to live in.我一生中参观过许多动物园，我从未见过一个我喜欢的或者适合动物住的。
6. They are like living textbooks for young people.它们就像年轻人的活教科书。

2. I agree with you. 我同意你。
3. There used to be a lot of manatees. 过去有许多海牛。
二、精讲巧练1. We are trying to save the manatees. 我们在尽力挽救海牛。
点拨：（1）本句的时态是现在进行时，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的时刻进行，而是在包括说话时刻在内的一段时间当中进行。
例如：My mother is writing a novel now. 我妈妈目前在写小说。
（2）动词短语try to do something意思是“尽力做某事”；try doing something表示“试着做某事”。
例如：He tried to read more, but it was too dark to read.他想要多看会书，但是天太黑了以至于不能看了。
They tried to solve the problem. 他们尽力解决这问题。
He tried pulling the door, and opened it at once.他试着拉了拉门，门一下子就开了。
随时练：【考例】They were trying ______ the child but they failed at last.A. saveB. to saveC. savedD. saves【答案与解析】答案是B。
动词try的后面用动词不定式表示“尽力做某事”的意思。
从句子的意思“他们在尽力挽救那个男孩，但最后失败了”可以判断是用动词不定式。
2. I am like this animal because I am strong and intelligent.我像这种动物，因为我强壮而且聪明。
点拨：（1）句子的like是介词，意思是“像”，它和一些连系动词be，look和seem等连用构成动词短语，表示“长得像、看起来像、似乎好像”的意思。
例如：It looks like my cat. 它看起来像我的猫。
（2）like的前面可以用very, much，rather，quite等修饰表示“很像、非常像、相当像、十分像”的意思。
例如：You look very much like your father. 你看上去非常像你的爸爸。
随时练：【考例】The boy _____ his mother, not only tall but also thin.A. likesB. likeC. look likeD. looks like【答案与解析】答案是D。
本句子的like是介词，和连系动词look连用表示“长得像”的意思，主语是第三人称单数形式，所以连系动词用looks。
3. There used to be a lot of manatees. 过去有许多海牛。
点拨：句型there used to be是there be的中间加动词短语used to表示“过去曾经有而现在没有”的意思。
There be的中间可以加will表示将来有；加情态动词may/can/must表示“可能有、一定有”的意思。
例如：There used to be a tall building in front of our school.在我们的学校前面曾经有一座大楼。
随时练：【考例】There ______ be an English party tomorrow. Would you like to go with me?A. canB. may C used to D. will【答案与解析】答案是D。
本句子的时间状语是tomorrow表示一般将来时，所以用will 表示“将来有”的意思。
4. I am writing to say that I am against building a new zoo in our town.我写信是想说我反对在我们镇建公园。
点拨：（1）against是介词，此句中意思是“反对”，反义词是for（赞成），后面如果接动词时要用动名词形式（动词-ing形式）。
No one is against this proposal. 没有人反对这个提议。
We are all against inviting such a person to the party.我们都反对邀请这样一个人参加晚会。
（2）against 还有“倚着、靠着、逆着”等意思。
We sailed against the wind. 我们逆风行船。
He placed the ladder against the wall. 他把梯子靠在墙上。
随时练：【考例】He agreed to most of the plan, but ________ starting it now.A. forB. was forC. againstD. was against【答案与解析】答案是D。
选项D意思是“反对”，against是介词，作谓语时必须加be。
选项B意思是“赞成”，不合句意。
句意：他对这个计划的大部分内容都赞成，但是反对现在开始实施。
5. I have visited a lot of zoos in my life, and I have never seen one I liked or one that was suitable for animals to live in.我一生中参观过许多动物园，我从未见过一个我喜欢的或者适合动物住的。
点拨：（1）连词and引导的是并列句，第一个句子是现在完成时I have visited a lot of zoos in my life；第二个句子中的动词seen后面用两个宾语one。
第一个one有定语从句I liked 修饰，第二个one有that引导的定语从句修饰。
（2）动词短语be suitable for somebody to do的意思是“适合某人做某事”，句子后面的to livein中的in不能省略，因为前面的one是此介词的宾语。
This toy is not suitable for young children to play with.这个玩具不适合小小孩玩。
（3）in one‟s life 一生，一辈子Lei Feng did lots of good deeds in his life.雷锋一生中做了许多好事。
随时练：【考例】There is not enough space for everyone _______.A. to stand onB. to standC. standing onD. standing【答案与解析】答案是A。
本句子是考查动词不定式的用法，for everyone to stand on 中的介词on不能省略，因为它带有逻辑宾语，即前面的名词space，去掉on就成了stand a place，应该是stand on a place。
