because的基本意思是“因为”,强调直接造成某种结果的理由和原因,所引导的原因状语从句多置于主句之后,有时为了强调,也可置于主句之前,并用逗号与句子的其他部分隔开。

because还可用来引导让步状语从句,这时,通常用于否定句或疑问句中。

because有时还可引导表语从句。

because可用于强调句。

not...because...结构有时否定主句，有时否定从句，须根据上下文正确判断。一般来说，否定主句时because前多有逗号，而如果because前有just，则多半否定从句。

because可用于省略句。

conj.(连词)因为他病了,所以他没去上学。

误 Because he was ill, so he didn't go to school.

正 Because he was ill, he didn't go to school.

析 在英语中,如果原因状语从句用because引导,主句就不能用so; 反之,主句用so,从句就不用because。
