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 didn't 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。

3.原因状语从句

你好。

以下也是原因状语从句； As / Since he is ill, he can't come.

同样，它也可以变成强调句：

It is as / since he is ill that he can't come.

所以，依据是：在英语句子中，你想强调的任何部分都有可能成为强调句的一部分。The question is whether you will do it or not, breaking out of the so called grammatical rules.

4.那些词可以引导原因状语从句

1. because因为，强调直接原因。如：

I study English because it is useful for my work.

我学英语因为它对我的工作有好处。
