原因英文（表示原因的三种英语表达方式归纳）

表达原因的多种方式：

一、从属连词because/ as /since /和并列连词for.如：

I did it because they asked me to do it. 我做了这件事是因为他们请我做的。

As it was raining ,you’d better take a taxi .天在下雨，你最好乘出租车去。

Since we have no money ,we can’t buy it. 我们没有钱，所以我们没法买。

I asked her to stay to tea, for I had something to tell her .我请她留下来喝茶，因为我有点事要告诉她。

解析：1.这四个词语气逐级递减。2.because 表示直接的原因或理由，重点在从句，常译为

“因为”；since 表示对方已知，无需说明的既成事实，中心句在主句，常译为“既然”；as 表

示明显的原因，重点在主句，常译为“由于”；for是个并列连词，只能放在另一个并列句

后面，表示一种推理或解释，或用作附加说明，并不指理由或原因，一般不放在句首，常译

为“因为”，“其理由是”（for表示因果关系时可以同because交替使用，但for前须用逗号，而

because则不必。
