asas用法讲解
“as...as...句型”是由两个as组成的,其中第一个as的词性是副词,词义是“同样地”,第二个as可用作介词(后接名词或代词)或连词(后接从句)。
(1) 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) 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+复数名词+as”。如:
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。
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:
She is as good a teacher as her mother. 她和她妈妈一样是位好老师。
(3) 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。
