原因状语从句 (1) 原因状语从句通常由 because, si nee, 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弓I导原因状语从句，相当于 now that，意思是 因为........ ，既然 ..... ,鉴于 ...... ”。 例如：Si nee the rain has stopped , let ' s go for a walk.既然雨停了，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 例女口 : As he has no car, he can ' t get there easily.
Since we have no money, we can
(4)for表示所说的理由是一种补充说明
' t buy it.
as和since引导的原因状语从居多放在句首。

Mother lives so far away that we hardly ever 在由such…that引导的结果状语从句中，
such是形容词，它修饰的可以是单数或复数可数名词，也可以是不

=The film was so won derful that all of us wan ted to see it aga in.
