as…做宾补,as是介词还是连词,还是都是?as后可以接什么?

如题所述

as long as :第一个as是副词,表示程度;第二个as是连词,连接从句。
as作副词,表示程度,意为“同样地”。eg:
Jack is as tall as his father.杰克和他的父亲一样高。
He doesn't speak English as/so fluently as you.他的英语说得不如你流利。
as作连词,引导原因状语从句,与because的用法相近。eg:
I must stop writing now,as I have rather a lot of work to do.我必须停笔了,因为我还有许多工作要做。

2、when the pizza certificates stop as the incentives program winds down, reading might actually decline.
as 是连词,引导原因状语从句,与because的用法相近。eg: I must stop writing now,as I have rather a lot of work to do.我必须停笔了,因为我还有许多工作要做。

3、当然,as也有介词词性,不过在这两句中没体现出来。
eg; As a writer,he was famous.作为作家,他是很有名的。

连词通常用来引导从句,(并列连词还可以连接单词或词组),连词有两类,
1)并列连词(记住即可)
and, but, so, or, for,
2)从属连词,就是那些引导主语从句、宾语从句、状语从句、定语从句的关联词语,如:
that, whether, what, when, why, how, where, who, whose, which, after, before, until, as soos as, if, because, than, as, .

介词只能引出单词或词组,而且介词后如果是人称代词就要用宾格,如果是动词就要用动名词,介词短语一般在句子中做定语、表语、状语、宾补。如:
in, on, at, by, with, of, to, through, for, .

当然,有时一个词可能既是介词,也是连词,这就需要认真地研究后面跟的什么了。如:
I get up after six every day.我每天6点之后起身。(after是介词)
I get up after my mother does.我在我母亲(起身)后起身。。(after是连词)
