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。
(1) swamp意为“沼泽；沼泽地”，既可做可数名词，也可做不可数名词。
例如：There is some swamp in that province.那个省有一些沼泽地。
Those swamps are the best places for this kind of animal to live in.那些沼泽地是这种动物生活的最好地点。
(2) 本句的时态为现在完成时，表示一个发生在过去的动作对现在造成的影响及过去的动作、状态一直延续至今并有可能继续下去，强调的是现在的情况，所以现在完成时不能和确定的表示过去的时间状语连用。
例如：She has never read the book.她从未读过那本书。
We’ve been up for two hours.我们已经起来两个小时了。
4. I am writing to say that I am against building a new zoo in our town.我写信是要说我反对在我们城市建一所新的动物园。
(1) 短语be against (doing) sth. 意为“反对（做）某事”，而be against sb. 意为“反对某人”。
例如：I’m against putting off the meeting.我反对将会议延期。
They were against taking part in the activity.他们反对参加这项活动。
His father is always against him.他父亲总是反对他。
(2) 反义词：be for sb. / sth. 支持某人/某事5. I’ve visited a lot of zoos in my life, and l have never seen one I liked or one that was suitable for animals to live in.我一生中参观了很多动物园，但从未看见一个我喜欢的或是适合动物生存的动物园。
(1) 本句为并列复合句，由and连接的第二个分句中包含了两个定语从句，即l liked为定语从句修饰第一个one，that was suitable for animals to live in为修饰第二个one的定语从句。
在先行词one和定语从句I liked间省略了关系代词that，因为此时关系代词that在定语从句中做宾语，常可省略；而第二个one与定语从句间的关系代词that却不能省略，因为此时that在定语从句中做主语，不可省去。
例如：I mean the one that was bought yesterday.我指的是昨天买的那个。
(2) suitable做形容词，意为“适合的；适宜的；恰当的”；如be suitable (for sb.) to do sth.表示“适合某人做某事”。
例如：The park is suitable for children to play game.这个公园适合孩子们做游戏。
(3) suitable for... 意为“适合于……的”。
例如：It’s a place suitable for a picnic.那是个适合野餐的地方。
6. In 1972, if was discovered that they were endangered.1972年，发现它们濒临灭绝了。
(1) 句中的it为形式主语，代替that从句，that从句是句子的真正主语it做形式主语时还常用于下列结构。
例如：It’s said that there will be an exam soon.据说，很快就要考试了。
It is known that the movie star has gone to Paris.众所周知这位影星去巴黎了。
It’s reported that the weather is getting worse.据报道，天气会变糟。
It is said that there an several thousand languages in the world.据说世界上有数千种语言。
(2) it代替名词性从句做形式主语，主要用于“it + be +形容词/名词/过去分词+ that从句”结构。
例如：It was a pity that the president couldn’t come.可惜校长没能来。
It is important that we should learn English well.学好英语很重要。
(3) discover 做动词，意为“发现”，指的是发现原来已存的，但不为人知的事物。
可接名词、代词、带疑问词的动词不定式、wh-从句、that从句做宾语，也可以接复合宾语，可用于被动语态。
例如：Recently they have discovered a comet.最近他们发现了一颗彗星。
（接名词）7. They provide homes for many endangered animals and help to educate the public about caring for them.他们为濒临灭绝的动物提供家园，而且帮助教育大众来关心它们。
educate为动词，意为“教育；培养”，名词为education，形容词为educational。
The girl was educated at the teachers’ college.这个女孩曾在师范院校读过书/受过教育。
相关词组：(1) educate sb. to do sth. 教育某人做某事；培养某人做某事。
He wants to educate the player to be the champion in Olympic Games in 2008.他想把这个队员培养成2008年奥运会的冠军。
(2) educate sb. about sth. / doing sth.Parents should educate their children about speaking to the old politely.家长应当教育孩子们对老人有礼貌地讲话。
(3) care for; take care of 关心；照顾8. I urge all of your readers to visit our wonder zoo soon.我强烈要求所有的读者赶快来参观我们漂亮的动物园。
(1) urge是动词，意思是“竭力主张；强烈要求”，常用词组为urge sb. to do sth. 主张某人做某事。
例如：We urge all the people in the world to prevent the AIDS.我们主张全世界所有的人都来预防艾滋病。
(2) urge还可表示“驱策；推进”。
例如：The manager urged his staff on.经理督促职员更加努力。
(3) 常用短语：urge against 极力反对urge sb. into doing sth. 怂恿某人做某事9. It’s also at home that we save energy and recycle …在家里我们也节约能源、循环利用……这是一个强调句，在初中阶段不要求被掌握，只明白其意思就可以了。
如：It is from the sun that we get light and heat.我们正是从太阳那里得到光和热的。
10. Do you care about protecting the environment and saving energy?你关注环境保护和节约能源吗？care about可以表示“关心，重视；介意，在乎”。
如：Most parents care very much about their children’s future.大多数父母都特别关心自己孩子的将来。
拓展：(1) care这个词的用法很多。
这里简要地做些讲解，其他的用法请同学们以后留心整理。
carefor sth. 用于否定句或疑问句中，常与would连用，表示“愿意或同意做某事；希望或喜欢做某事”。
如：Would you care for going for a walk with me?愿意和我一起去散步吗？(2) care for还有“照看；照顾”的意思，与我们以前学过的take care of和look after同义，常用于被动语态中。
如：Old people are cared for by the whole society.老年人受到整个社会的照顾。
