1、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 arent going there?-Because I dont 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”。例如：Since the rain has stopped，lets go for a walk.既然雨停了，我们出

5、nderful film that all of us wanted to see it again.=The film was so wonderful that all of us wanted to see it again.(3)如果名词前由 many,much,little,few等词修饰时，只能用 so,不用 such。例如：Soon there were so many deer that they ate up all the wild roses.He has so little time that he cant go to the cinema with you.(4)如
6、果主从句的主语相同，并且从句是否定的形式，可以用 too.to.句型转化。例如：He was so excited that he couldnt go to sleep that night.=He was too excited to go to sleep.(5)如果主从句的主语相同，但从句是肯定的形式，可以用 adj.+enough替换。例如：He is so old that he could go to school.=He is old enough to go to school.他够大了，可以去上学。练习：It is _ hot in the room _ we have t
