As FAr As i know是什么从句

条件状语从句 As far as I know 据我所知 As/So long as we don’t lose heart,we’ll find a way to overcome the difficulty.只要我们不灰心,我们就能找到克服困难的方法. As/So far as I know,he is an expert on DNA.据我所知,他是一个DNA专家.

这个一般当成插入语的, 就像I think,I'm afraid等等 一样的,因为他跟全句句义 没有直接关系!

解释如下: as far as引导状语从句,强调程度或范围 例句: It only lasted a couple of years, as far as I know 据我所知,它仅仅维持了两三年。

据我所知 没有主语

as的九大用法: 一)as作副词,表示程度,意为“同样地”。在“as...as...”,“not as...as...”结构中的第一个as是副词,作“和/与...(不)一样”解。eg: Jack is as tall as his father.杰克和他的父亲一样高。 He doesn't speak En...

as far as 只要 肯定是从属句了

i don't think it matters as far as the weather is concerned 是状语从句

C 试题分析:考查状语从句的省略。A如果有一些;B如果这样;C如果曾经有过;D如果不;句意:据我所知,如果从句有过,他也很少会缺席。If ever="If" he has ever been absent from school。如果他参加缺席上学。点评:当状语从句的主语与主句的...

He is as tall as me. He runs as fast as Tom.
