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。

Travelling with kids is good f 1 them. They can find new interests. Travel makes information alive for kids, and makes it much more exciting than studying textbooks or d 2 experiments in the lab. While traveling, they learn h 3 to deal with new situations, and communicate with other people. They learn patience, because sometimes i 4 takes a long time to get to some exciting or interesting places.I’ve been traveling since I was seven years old. For me, to stop traveling would be like taking something a 5 from my soul（灵魂）. I can’t live without traveling and I wouldn’t be who I am if I don’t travel. Some people think it’s h 6 to travel after having kids. But in my opinion, when people become parents, it doesn’t m7 they couldn’t travel any more. My children have been traveling since they were three weeks old.Bringing a new life into the world comes with many responsibilities（责任）and I’d love to be a good mother. One of my duties is to e 8 my children. I’m so thankful that my parents took me on family trips when I was y 9 .I’ve learned that the outside world is more colorfu l than the little one I was living in.

如：He becomes a teacher.他成了一名老师。
(2)get多用于口语，表示一种变化过程，强调的是“渐渐变得”，后常接形容词的比较级形式。

如：You'd better cut the article down to about 2，000 words.你最好能把这篇文章压缩到两千字左右。
