（2007年）51.There are as good fish in the sea -------ever came out of it.

A.than

B. like

C.as

D.so

翻译：海里的好鱼是取之不尽的。

答案：C.解析：这是一句英语谚语，指虽然失去一个机会，还会有很多机会。原句不是比较级句型，不能用than；like 作为介词或动词，后不能跟动词；so作为副词，后面也不能跟动词，so 作为连词连接的是整个句子；as 常用作关联词后置于so或as表示同等的程度或量。

（2008年）55.--------he wanted to go out with his friends at the weekend, he had to stay behind to finish his assignment. A。Much though B.Much as C.As much D.Though much 翻译：尽管他想周末和朋友一起出去，但他不得不留下来完成作业。

答案：B. 解析：让步状语从句多由although和though引导，但是也可以把让步的成分（形容词、副词、动词）提前，此时用连词as或though. 例如：Poor as/though he was, he was honest；Try as you will, you won’t manage it.；

Much as I admire him as a writer, I do not like him as a man.从语法的角度来看，使用倒装形式的让步结构时，既可以用as, 也可以用though, 但是把though 用于倒装结构多属于口语。

（2012年）61.Which of the following contains an adverbial clause of cause?

A.I got a job as soon as I left university.

B.As there was no answer, I wrote again.

C.You must do the exercises as I show you.

D.Wealthy as he is, Mark is not a happy man.

答案：B. 解析：选项A中as soon as I left university是时间状语从句。选项B中as 为连词，相当于because,引导原因状语从句。选项C中as“像.......一样”是连词，引导方式状语从句。选项D中，as为“尽管”引导让步状语从句，且该句使用倒装结构。

一、as作连词的用法

1. as...as的用法

as...as意为"和……一样"，表示同级的比较。使用时要注意第一个as为副词，第二个as为连词。其基本结构为：as+ adj./ adv. +as。例如：

(1)This film is as interesting as that one.这部电影和那部电影一样有趣。

若有修饰成分，如twice, three times, half, a quarter等，则须置于第一个as之前。例如：

Your bag is twice as expensive as mine.你的袋子比我的贵一倍。
