在高三课本第十五单元出现了下面几个句子:
1 As Kofi Anna,Secretary General of the United States said,each contribution -- how small -- can help make a difference.
2 Now she is spending a year in remote part of southwest China working as a volunteer teacher in a village school.
这几个句子都涉及到了as的用法。作介词用,第一句话中as用作关系代词,引导定语从句,含义为正如,第二句话中as的含义为作为,当作,做介词。
下面让我们结合历年高考试题对其用法进行分析。
一.用作连词引导让步状语从句
从句必须用倒装语序,把作表语用的名词或作表语的形容词,或动词,或副词提到as前面。如:
1.Child as he is,he knows a lot.
2.Tired as they were,they stayed up late preparing for the coming exams.
3.Try as he would,he failed again this time.
考例:1.___,he talks a lot about his favorite singers after class.
A.A quiet student as he may be
B.Quiet student as he may be
C.Be a quiet student as he may be
D.Quiet as he may be a student
【解析】答案是B。作表语的是名词student,名词前不加冠词。
2.____,Carolina,couldnt get the door open.
A.Try as she might B.As she might be C.She might as try D.Might she as try
【解析】答案是A。as引导让步状语,将动词原形try提到as前面。
二.用作关系代词,引导定语从句
as用作关系代词,引导定语从句,含义为正如。如:
1.He is very careful,as his work shows.
2.As is known is reported in the newspaper,talks between the two countries are making progress.

【解析】答案是D。引导非限制性定语从句。
三.作为副词
用于表示和一样,的意思,asas中间要用形容词/副词的原级,如as long as:长达;as far as远达;as much as:多达;as tall as含义为高达。如:
That day they walked as far as ten kilometers in two hours.
