(一)原因状语从句引导原因状语从句的常见连词或短语:as, because, since, now that, considering that, seeing that(鉴于……)。

注意以下几点:1. because, since, as, for, now thatbecause语气最强,用于回答why的提问,可与强调词only, just 以及否定词not 连用。

但不可以与so 连用。

since 引导的从句语气次于because引导的从句,常表示稍加分析后而推断出的原因,或指人们已知的事实,比as正式一些,常置于句首。

as 语气最弱,其原因只是对结果的附带说明,一般放在句首。

for虽然解释为“因为”但只是一个并列连词,它也常引导句子表示原因,但不是原因状语从句,它是一个并列句。

for所提供的理由是一种补充性的说明,表示推测的理由。

now that意为“既然,由于”。

表示由于人们已知的事实或正在发生的事而产生某个结果。

He failed because he was careless.他因粗心而失败了。

Since everyone has come, let’s begin our meeting.既然大家都来了,我们开会吧。

As all the seats were full, he stood there.所有的座位都满了,他只好站那儿。
