精品- 常见词as用法总结 近几年高考中有关as一词的题目出现过很多次，其中as或是最佳选项，或是干扰项，或是题干中的关键信息点，涉及as作为连词、介词、关系代词、副词以及习语等各种用法。现结合高考试题将as的用法归纳如下： 一、 用作连词的as 1. 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 she did 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。例如：As time went by, we found he was an honest man./As he grew older, he lost interest in everything except gardening. 例1 It wasn’t until nearly a month later________ I received the manager’s reply. A. since B. when C. as D. that 解析：本题中的as与when一起作为干扰项，容易使同学往时间状语从句上思考，事实上本题是强调句，正确选项是D。 精品- 精品- 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, the good model will always be in demand. A. While B. Since C. As D. 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 he would, he couldn’t open the door. 例3 _____ he has limited technical knowledge, the older worker has a lot of experience. A. Since B. Unless C. As D. Although
