状语从句总结

一、原因状语从句

(1)原因状语从句通常由 because, since, as, for引导。

(2)because表示直接原因，语气最强。 because引导的原因状语从句多放在主句之后。回答 由why提出的问题，只能用 because。此外，because和so不能同用在一个句子里。

例如： Why aren' t going there?——Because I don ' t want to.

since引导原因状语从句，相当于 now that ,意思是 因为??…，?既然??…；鉴于……o 例如：Since the rain has stopped, let ' s go for a walk.然雨停了，我们出去散散步吧。

as和since语气较弱，一般用来表示明显的原因。由 as和since引导的原因状语从居多放 在句首。

例如 ：As he has no car, he can ' t get there easily.

Since we have no money, we can ' t buy it.

(3)for表示所说的理由是一种补充说明 ，for引导的从句一般不放在句子的开头。如 ：

I decided to stop and have lunch, for I was feeling quite hungry.

练习： I was late for class yesterday there was something wrong with my bike.

He took off his coat he felt hot.
