1.引导原因状语从句的从属连词主要有because，as，since，seeing (that)， now (that)，not that … but that。如：

They can't have gone out because the light 's on.

他们不可能出去了，因为灯还亮着。

Since you are going，I will go.既然你去，我也去。

Now that all are present，let's start the discussion.

既然全部出席了，我们就开始讨论。

既然外边在下雨，我们最好待在室内。

Now that you are here，you ’d better stay.

你既然来了，最好还是留下吧（既来之，则安之）。

2.除以上提到的大家比较熟悉的引导原因状语从句的从属连词外，when有时 也可引导原因状语从句，其意既然。

如：

I can't tell you when you won't listen.

既然你不想听，我就不告诉你了。 

3.because习惯上不与so连用。汉语习惯上说因为所以，但英语习惯 上却不能将so与because连用。如：

【正】 Because it was raining，we stayed at home. / It was raining，so we stayed at home.

【误】 Because it was raining，so we stayed at home.

因为下雨，所以我们待在家里。

4.because从句与because of短语的转换。because后跟句子，because of跟短语，二者可以转换。如：

He can't come because he is ill. / He can't come because of his illness.

他因病不能来。

I said nothing about it because his wife was there. / I said nothing about it because of his wife ’s being there.

因为他的妻子在那儿，我对此事只字未提。
