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 United1 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(不加冠词)或作表语的形容词,或动词(原形),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.(2005重庆)___,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.(2005.广东)____,Carolina,couldn't 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 known2 is reported in the newspaper,talks between the two countries are making progress.

考例:(2005浙江)___I explained on the phone,your re quest3 will be considered at the next morning.

A.When  B.After  C.As  D.Since

【解析】答案是C。意思是“正如我在电话里解释的那样……”。

2.(2006)The Beatles,____many of you are old enough to remember,came from Liverpool4.

A.what  B.that  C.how  D.as

【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,as…as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.

考例:(2005安徽)John is the tallest boy in the class,_______according to himself.

A.five foot eight as tall as B.as tall as five foot eight  C.as five foot eight tall as  D.as tall five foot eight as

【解析】选B.as…as中间要用形容词/副词的原级。

四.引导时间状语从句

含义为“当…的时候”,如:

1.I watched her as she combed her hair.

2.As he grew older ,he lost interest in everything except gardening5.

考例:1.(NMET1994)Mother was worried because little Alice was ill,especially____Father was away in France.

A.as  B.that  C.during  D.if

【解析】答案是A.“在……时候”,相当于when.而C选项是介词,不接句子。

2.(MET90)_____the day went on,the weather got worse.

A.With    B.Since    C.While    D.As

【解析】答案是D.“随着”的意思,as the day went on可以作为固定结构记住。

五.作介词用

有“作为,当作”的意思。如:

1.They were all dressed as clowns6.他们都打扮得如小丑。

考例:(2005广东)I feel that one of my main duties_____a teacher is to help the students to become better learners.

A.for  B.by  C.as  D.with

【解析】选C。“作为教师”的意思。
