现结合高考试题将as的用法归纳如下:一、用作连词的as1. 引导时间状语从句,表示“当……的时候”,其用法与when和while类似。
例如:As a child (When he was a child), she was sent to six different schools. 此用法中as多表示从句与主句动作同时进行,一般不与状态动词连用,意为“一边……一边……”。
例如:She sang songs as shedid her homework.as 还可以表示一动作紧接着另一动作发生,说明另一动作的结果,有“随着……”的含义。

2. 引导原因状语从句,表示“由于,因为”,相当于because, 但通常置于句首。
例如:As he is a qualified doctor, I trust his advice on medical matters.例2_____ modeling business is by no means easy to get into, thegood model will always be in demand.A. WhileB. SinceC. AsD. If解析:本题中as干扰性很强,很多同学误以为是原因状语从句,但仔细分析不难发现正确答案应是A(while表示“只要”)。
3. 引导让步状语从句,通常可与although或though通用,但语序不同,although或though用于句首,as用于倒装结构。
例如:Young as I am, I already know what career I want to follow. /Although(或Though)I am young, I already know what career I want to follow.as 表示让步用于倒装结构,通常将从句的表语、状语或动词前置。
如果表语有冠词a/an, 需去掉。
例如:Great scholar as he is, he is lacking in common sense./Much as I like you, I couldn’t live with you. / Try as hewould, he couldn’topen the door.例3_____ he has limited technical knowledge, the older worker hasa lot of experience.A. SinceB. UnlessC. AsD. Although解析:as 虽然有引导让步状语从句的用法,但本题不是倒装结构,故正确答案应是D。
4. 引导方式状语从句,表示“如,像”。
例如:When in Rome, do as Romans do./Do to others as you would have others do to you.例4We wanted to get home before dark, but it didn’t quite ______ asplanned.A. make outB. turn outC. go onD. come up解析:本题考查动词词组辨析,题干中的“as planned”提供了重要信息,答案选B。
