as as的用法总结
as as的用法总结如下
其中的第一个 as 为副词,其后通常接形容词或副词(用原级),第二个 as 可用作连词(后接从句)。
as … as …的用法
基本用法:
虽然都是 as .… as …但在不同的语境下,意思也不同 例如:
1.表示不同人或物同一性质的比较,意为"……和……一样……"
2.表示同一个人或物不同性质的比较,意为"既……又……"
3.用于表示两个人或物不同性质的比较,表示程度相同或相当,意为"……且 而……"。
例句: He was as handsome as his wife was beautiful .他长得非常英俊,他的妻子也长得非常漂亮。
He was as experienced as his brother was green .他经验丰富。而他兄弟却涉世未深。
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 "
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 wantit ..无论多少人吃都够了。
