什么是原因状语从句?

答案

其他答案(2)原因状语从句x0d要点:由连词because,since,as引导,也可由for,now that 等词引导x0d1.I didn’t go to school yesterday because I was ill.x0d我昨天没去上学,因为我生病了.x0d2.Since everybody is here,let’s begin our meeting.x0d既然大家都来了,让我们开始开会吧.x0d3.As you are in poor health,you should not stay up late.x0d既然你身体不好,你就不该熬夜.x0d4.I asked her to stay to tea,for I had something to tell her.x0d我请她留下来喝茶,因为我有事要告诉她.x0d.难点——because ,since ,as ,for,辨析x0d1） because语势最强,用来说明人所不知的原因,回答why提出的问题.当原因是显而易见的或已为人们所知,就用as或 since.x0dI didn’t go,because I was afraid.x0dSince /As the weather is so bad,we have to delay our journey.x0d2） 由because引导的从句如果放在句末,且前面有逗 号,则可以用for来代替.
