短语·巧记·典句·考点

　　be caught in 被困于......

　　【巧记提示】 be(表被动)+caught（抓）+in（在......里）

　　【经典例句】 I am often caught in a heavy traffic on my way to school.

我在上学路上常常遇到塞车。

　　【考点聚焦】 1)同义词组:be trapped in

　　2）与catch搭配的短语动词中，如果含有名词，注意被动意义的表达。例如:

All the toys in the shop caught the children's attention/eye.

　　=All the children's attention/eye was caught by the toys in the shop.

　　=The shop had all the children's attention/eye caught to the toys.

　　孩子们的注意力都被商店的玩具所吸引。

　　do one's best 尽力；努力

　　【巧记提示】 do(做）+one's（某人的)+best(最好的)

　　【经典例句】 I don't know if I can make great progress,but I'll do/try my best.

　　我不知道能否取得进步，但是我会尽力的。

　　【考点聚焦】 1）辨析try one's best，try as hard as one can和do what one can:

　　do/try one's best动词后是名词短语形式one's best； 

　　do/try as hard as one can动词后是状语从句形式as hard as one can； 

　　do what one can to 动词后是宾语从句形式what one can。

　　2）以上结构之后用不定式to do 表示目的状语。例如:

I'll try my best to/try as hard as I can to/do what I can to help you if possible.有可能我会尽力帮助你。

3）注意例句中的can to，这是考试中常设计的考点之一。原来，在例句中can 之后省略了动词do。即:I'll try as hard as I can/do what I can ( do ) to help you if possible.

　　too much 太多

　　【巧记提示】 too(太）+much（多）

　　【经典例句】 Too much carbon dioxide pollutes the air.

太多的二氧化碳污染空气。

　　【考点聚焦】 1）too much和much too的区别:

　　too much 后接不可数名词，这时much 相当于一个形容词。

　　much too作副词解，修饰形容词和副词，后接形容词、副词，意思为"极其；非常"。 2）too many和 too few 前不用much。例如:

　　There are far too many people here.这里人实在太多了。

　　cut down 砍下（倒）

　　【巧记提示】 cut(砍)+down(向下地)→向下砍→砍倒

　　【经典例句】 Many trees have been cut down in the past 20 years in my hometown.

　　过去20年家乡的许多树都被砍了。

　　【考点聚焦】 cut down 的其他含义:

　　1）意思是"砍倒（树等）"，例如:

All the big trees have been cut down.所有的大树都被砍倒了。
