归纳讲解

一、原因状语从句的引导词

引导原因状语从句的从属连词主要有because， as， since， for， seeing （that）， now （that）， considering （that）， in that等。

（一） because， since， as和for的区别

because引导的原因状语从句一般位于主句之后，because表示直接的原因，语气最强，从句是全句表达的中心，也用来回答由 why引导的特殊疑問句;since引导的原因状语从句一般位于主句之前，表示已知的事实，通常被翻译成“既然”，较为正式，语气比because弱;as 引导原因状语从句时表示附带说明的双方已知的事实或比较明显的原因，语气比since弱，较为口语化，位置较为灵活，常与since换用;for引导的原因状语从句并不说明主句行为发生的直接原因，只提供一些辅助性的补充说明或推断原因，for引导的原因状语从句只能位于主句之后，并且必须用逗号将其与主句隔开。例如：

He didnt attend the meeting yesterday because he was ill. 他昨天没来开会是因为生病了。（he was ill是他没来开会的直接原因，也是全句表达的中心。）

Since you are free today， you should help me with my mathematics. 既然你今天有空，你应该帮我补习数学。（you are free是附带说明的事实，着重点在主句。）

As it is raining， you should take a taxi. 既然在下雨，你应该乘出租车。（it is raining是附带说明的原因，不过其语气比since要弱，着重点也在主句。）

He must be ill， for he is absent today. 他今天没来，一定是生病了。（主句he must be ill是从he is absent today推断出来的，它们之间不存在因果关系。）
