原因状语从句就是在复合句中表示主句动作发生原因的状语从句。用于引导原因状语从句最常用的连词是because,另外还有as, since以及now that等。

1. 用because引导:because是引导原因状语从句最常用的连词,其意为因为。如:

The little boy was crying because he was lost.

那小孩因迷路而哭。

I bought the house simply because it was large.

就是因为这所房子大我才买的。

2. 用as引导:as也可以用于引导原因状语从句,意思是由于。如:

As he is ill, he cant come to the meeting.

由于生病了,他不能来参加会议。

As you werent there, I left a message.

由于你不在那儿,我留了个信儿。

3. 用since引导:since引导原因状语从句时,意思是既然。如:

Since you ask, I will tell you.

你既然问,我就告诉你。

Since you are going, I will go.

既然你去,我也去。

4. 用now that引导:now that引导原因状语从句的意思也是既然。如:

Now that you have come you may as well stay.

既然你来了,你就留下。

Now that youre growing up you must learn to stand on your own two feet.

你既然已经长大成人,就得学会独立生活。

5. 习惯用法:不要受汉语意思影响将表示因为的连词与表示所以的 so 连用。如:

■既然你很忙,那就不必来了。

误:As you are busy, so you neednt come.

正:As you are busy, you neednt come.

正:You are busy, so you neednt come.

as是从属连词,在此引导原因状语从句;so 是并列连词,在此连接一个并列句,所以误句结构混乱,应去掉其中一个。
