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。

3. The air is badly polluted. 空气被严重污染。
4. The method is not only cruel, but also harmful to the environment. 这种方法不仅残酷，而且对环境也有害。

2. Not only can the art bring happiness to others, but it also shows that even cold, hard iron can be brought back to life with a little creativity. 不仅艺术品能给人们带来快乐，而且冰冷坚硬的钢铁在艺术创作下也恢复了生命。
重要句型详解：1.To cut down air pollution, we should take the bus or subway instead of driving. 为了减少空气污染，我们应该乘坐公共汽车或者地铁，而不是开车。
cut down 意为“减少”；是“动词+副词”结构的短语，所带的宾语为名词时，宾语可位于down的前面或后面；为代词时，只能位于down前面。
You’d better cut the article down to about 2,000 words. 你最好能把这篇文章压到两千字左右。
【拓展】cut down 还可表示“砍倒”的意思。
They cut down the big tree. 他们砍倒了这棵大树。
辨析：spend, cost, take, pay2.Have you ever taken part in an environmental project? 你曾经参加过环境保护活动吗？辨析：join, join in 和take part inWill you join us in the discussion? 你参加我们的讨论吗？She joined the Young Pioneers. 她加入了少先队。
Why didn't you join in the talk last night? 昨晚你为什么没参加座谈？Did you take part in the sports meet? 你参加运动会了吗？3. We can’t afford to wait any longer to take action! 我们不能再等了，要采取行动了。
⑴ afford是动词，意为“买得起,担负得起”，通常与can, could, be able to连用,多用于否定句中。
They couldn’t afford $50 for a ticket. 他们拿不出50美元买一张票。
⑵ afford后面常跟带to的动词不定式。
We can’t afford to go abroad this summer. 今年夏天我们没有足够的钱出国。
4.And the gate in front of her house is made of rocks and old glass bottles. 她房子的前门是由岩石和旧玻璃瓶子制成的。
【辨析】be made + 介词4. Not only can the art bring happiness to others, but it also shows that even cold, hard iron can be brought back to life with a little creativity. 不仅艺术品能给人们带来快乐，而且冰冷坚硬的钢铁在艺术创作下也恢复了生命。
“not only … but also …”是一个并列连词词组，其意思基本等于“both … and …”。
使用not only … but also … 时须注意的几点：⑴ not only与but also后面所连接的词的词性必须对等：They completed the project not only punctually but also perfectly. 他们不仅准时完成工程，而且完成得很出色。
⑵ not only只能连用，而but also既可连用，也可分开用：Television is not only boring, but it also wastes a lot of time. 电视不仅乏味，而且还浪费许多时间。
⑶谓语动词的数应与but also后主语的数保持一致：Not only you but also Mr. Zhang teaches in this college. 不仅你，张老师也在此学院教书。
⑷ not only放在句首，后接句子时要用倒装结构：Not only had the poor man been fined, but also he had been sent to prison. 这个可怜的人不仅被罚款，而且还被送进了监狱。
6.Which parts need to be improved? 哪些部分需要被改善？辨析：need to be done; need doing与need to do⑴need doing=need to be done 需要被…现在分词doing表被动“需要被做”，相当于need to be done。
My watch needs repairing. =My watch needs to be repaired.我的表需要修了。
⑵ need后加不定式，证明need为实义动词，而非情态动词，这时need有人称和数的变化。
He needs to get up early. 他需要早起。
7.What or who is causing these problems? 什么或谁将会导致这些问题？cause用作动词，当“引起，造成，使得”讲。
一般指引起或造成不好的结果。
cause sb. sth.= cause sth. to sb.(后接间接宾语+直接宾语)为固定用法。
He caused his parents much trouble.= He caused much trouble to his parents. 他给父母带来很多烦恼。
