as as 的用法

问题描述

精选答案

中间接形容词或副词原级，在否定句中第一个as可为so；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；该结构修饰语可用almost、nothing like等修饰，修饰语须置于第一个as前等。

(1)基本用法该结构的基本意思是“与……一样”，其中接形容词或副词的原级，在否定句中，第一个as也可换成so。如：He doesn't study as[so]hard as his brother.他学习不如他弟弟努力。

（2）涉及数量或程度的用法若涉及数量或程度，可用“as much+不可数名词+as”和“as many+可数名词复数+as”。如：He doesn’t pay as much tax as we do/as us.他没我们交的税款多。There are not as many restaurants as there were.现在餐馆没有过去多了。

（3）有关词序的一点说明其间接形容词时，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)。如：I have as good a voice as you.我的声音和你一样好。

（4）该结构的修饰语根据情况可用(not)nearly,almost,just,nothing like,exactly,not quite,half,one-ten,twice,three times,30 per cent等修饰，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：This room is twice as large as that one.这个房间是那个房间的两个大。You’re not half as clever us you think you are.你远不是自己想像的那么聪明。It took three times as long as I had expected.这件事比我预料的多花了两倍的时间。
