使用asas结构的七个要点

1. 基本用法

中间只能用形容词或副词的原级,不能用比较级或最高级。如果在第二个as之后使用独立的人称代词,一般说来用主格(较正式)或宾格(非正式)均可。如:

He’s as old as she [her]. 他年纪跟她一样大。

但是,若第二个as之后的人称代词跟有谓语动词,则该人称代词只能用主格。如:

He is as old as she is.

但是有时用主格或宾格含义差别很大:

You love him as much as I (=as I love him). 你爱他像我爱他一样。

You love him as much as me (=as you love me). 你爱他像爱我一样。

2. 用于否定句

在肯定句中用as…as, 在否定句中用not as…as或not so…as 均可。如:

He doesn’t study as [so] hard as his brother. 他学习不如他弟弟努力。

3. 关于比较对象

使用该结构要注意比较对象的一致性,即比较的双方必须是可以比较的同类人或物,否则会出错。如:

你的房间与我的一样大。

正:Your room is as large as mine

误:Your room is as large as me.

4. 涉及数量或程度

如果涉及数量或程度可用:as much+ (不可数名词+) as / as many+ (可数名词复数+) as。如:

You must speak English as much as possible. 你必须尽可能地多说英语

You’ve made as many mistakes as I have. 你犯的错误和我犯的一样多。

5. 注意下列结构的词序

她和她妈妈一样是位好厨师。

正:She is a cook as good as her mother.

正:She is as good a cook as her mother.

误:She is as a good cook as her mother.(www.hxen.net)

6. 关于修饰语

修饰as…as结构的常见词语有nearly, almost, just, exactly, half, quite, twice, three times等,请注意这些修饰语都只能放在as…as 结构之前 (而不能置于其中或其后。如:

I earn half as much as you do. 我只赚你的一半钱。

This rope is twice as long as that one. 这根绳子比那根长一倍。

7. 省略用法

as…as结构在一定的上下文中可以用其省略结构(即省去其中的一个 as)。如:

She’s clever, but her brother is just as clever. 她很聪明,但她兄弟也一样聪明。

The woman married a man poor as herself. 这个女人嫁给了一个与她一样穷的男人。
