原因结果目的状语从句

10 逻辑关系（Logical relations）

(61) 原因和结果

表原因的词：becau, since, as, for, becau of

表结果的词：so

一、原因状语从句

(1)原因状语从句通常由becau, since, as, for引导。

(2)becau表示直接原因，语气最强。回答由why提出的问题，只能用becau。

此外，becau

和so不能同用在一个句子里。

eg：------Why were you late for school?------Becau I got up late.

since引导原因状语从句，相当于now that，意思是“因为……，既然……，鉴

于……”。

eg：Since the rain has stopped，let’s go for a walk. 既然雨停了，我们出去散

散步吧。

as和since语气较弱，一般用来表示明显的原因。由as和since引导的原因状语从

居多放在句首。

例如：As he has no car, he can’t get there easily.

Sin ce we have no money, we can’t buy it.

(3)for表示所说的理由是一种补充说明,for引导的从句一般不放在句子的开头。如:

I decided to stop and have lunch, for I was feeling quite hungry.

练习： I was late for class yesterday _______ there was something wrong with

my bike.

He took off his coat _______ he felt hot.

you can’t answer the question, I’ll ask someone el.

________the bad weather, we misd the train.

二、结果状语从句

(1)结果状语从句由so…that, such…that, so that引导。
