高中英语语法:原因状语从句
比较because, since, as和for:
1)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.例如:
I didnt go, because I was afraid. 我不去是因为我怕。
Since /As the weather is so bad, we have to delay our journey. 天气那么糟,旅行推迟了。
2)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。但如果不是说明直接原因,而是多种情况加以推断,就只能用for.例如:
He is absent today, because / for he is ill. 他今天缺席,因为他病了。
He must be ill, for he is absent today. 他一定病了,所以今天缺席。
