总结了关于as……as的用法,供大家学习使用。
一、as…as 结构的基本用法
其基本意思为“与……一样”,其中的第一个as副词,其后通常接形容词或副词(用原级),第二个as可用作介词(后接名词或代词)或连词(后接从句)。使用时应注意以下几点:
1. 在否定句中,第一个 as 也可换成 so:
He doesn’t study as [so] hard as his brother. 他学习不如他弟弟努力。
2. 在该结构的两个as之间通常接形容词或副词的原级,但若涉及数量或程度,可用“as much+不可数名词+as”和“as many+可数名词复数+as”:
You’ve made as many mistakes as I have. 你犯的错误和我犯的一样多。
I haven’t got as much money as I thought. 我不像原来想像的有那么多钱。(R2/92)
其间接形容词时,有时该形容词还可修饰另一名词,但这个名词应带有不定冠词(注意词序):
She is as good a cook as her mother. 她和她妈妈一样是位好厨师。
也可说:She is a cook as good as her mother.
但不说:She is as a good cook as her mother. 或They are as good cooks as us.
二、关于第二个as的词性
第二个as后接从句时,该as通常为连词,但有时这个as还充当其后从句的主语或宾语,此时该as实为关系代词。如:
I gave him as much as he could eat. 他能吃多少,我就给了他多少。
We’ve got food for as many people as want it. 我们的食物,无论多少人吃都够了。
注:若第二个as用作连词引导一个表示将来意义的从句,则该从句可用现在时表示将来,也可直接使用将来时态。如:
We’ll get there as soon as you do [will]. 你一到,我们就到。
三、as…as…结构的修饰语
该结构根据情况可用使用以下修饰语:(not) nearly, almost, just, nothing like, exactly, not quite, half, one-ten, twice, three times, 30 per cent等,并且这些修饰语必须置于第一个as之前,而不能置于其后。如:
He doesn’t play half as well as his sister. 他演奏的水平不及他姐姐的一半。
This dress is twice as expensive as that. 这件连衣裙比那件贵一倍。
四、as…as…结构的省略
在非正式场合(尤其是美国英语中),有时可以省略第一个as。如:
When over forty, he married a woman poor as himself. 他在40多岁时娶了一个像他本人一样穷的女人。
另外,若意思明确,有时可省略第二个as及其后的相关词语。如:
The pianos in that shop will be cheaper, but not as good. 那家商店的收音机会便宜些,但质量没那么好
