as宾补是什么

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）
