众所周知,as是个非常高频的词。充分学好as用法,即彻底弄明白as这个词的用法,无疑对英语的阅读理解能力的提升起到重大的作用。我们第1讲已经讲了as用作介词、副词和关系代词的用法,今天我们讲as用作连词的用法。

as可用作连词

as用作连词,有以下一些用法。

1、表示时间

(1)表示时间过程,作主句谓语动词所表示的动作发生的背景。

例如:

As they were walking,the rain began.

He came up just as I reached the door.

(2)表示两个同时演变的情况,作“随着......”解释。

例如:

3、表示让步

例如:

Much as I like ice cream,I never eat much at a time.

Try as he would,he could not lift the rock.

注意:表示原因的as,有时也可用这一形式,这要从上下文才能判断。

4、表示动作的方式,作“正如......”解释。

例如:

When in Rome,do as the Romans do.

5、表示比较

比较两个人或物在某方面相同用as...as,不相同用not so/as...as。

(1)第一个as前可用表示倍数、程度等得词或词语来修饰。

例如:

Tom is twice as capable as Jim.(汤姆的能力比吉姆强一倍。)

She's just/quite as clever as her sister.(她完全像她姐姐那样聪明。)

(2)如果句中有a/an,要注意语序。

例如:

It was as pleasant a day as we have ever spent.

She is as good an actress as her mother.

(3)as...as结构还可以下面形式出现:

例如:

He found riding as tiring as walking.

It is as easy as falling off a log.(=Falling off a log is easy.)

The message is as clear as clear as is necessary.(=as clear as it is necessary.)

(4)as...as结构中第二个as后人称代词的格的形式应和主句中与之相比较的人称代词一致。

例如:

You hate him as much as I.(=You hate him and I hate him,too.)

You hate him as much as me.(=You hate him and you hate me,too.)

但在口语中,只要不引起误解,第二个as后人称代词(尤其是第一人称)的主格可以用宾格表示。

例如:

My sister is as tall as me.(=My sister is as tall as I.)

(5)在非正式文体中,诸如下列结构中的第一个as可以省略。

例如:

Your face looks(as)white as snow.

You look (as)pretty as ever.

She's(as)hard as nails.
