时间状语从句(1)常用的连词有when, while, before, after, until(till),since, as soon as等. (2)时间状语从句中一般不用将来时,若谈论将来的事情,往往用一般现在时代替, 如：I’ll go on with the work when I come back tomorrow./As soon as he finishes the work, he will come to see me. (3)when和while都表示“当……的时候”,但有区别. when强调“特定时间”,如： There was a loud knock at the door when he was just falling asleep. while表示的时间是一段,而不是一点,如： While he was having supper, he heard someone knock at the door. while有时还有对比的含义,如： While I was reading, he was writing. 2.原因状语从句(1)常由because, since, as引导. (2)because表示直接的原因,着重点在从句,用于回答why,语气最强. I can’t go to school because I am ill. since一般表示对方已知的,无须加以说明的既成事实的理由,全句中心在主句,语气比because弱,常译为“既然”,如：Since you are ill, I’ll go alone. as表示十分明显的原因,一般说明因果关系,着重点在主句,语气较弱.常译为“由于”,如：As it is raining hard, we won’t go hiking. for是个并列连词,只能放在另一个并列分句后面,表示一种推理或解释,或用作附加说明,而不是指理由或原因,语气最弱,一般不放在句首,常译成“因为”,如：You haven’t met him, for he didn’t come here. 3.条件状语从句 常由if(假如、如果)No matter(不管)来引导,如：No matter what he says,I won’t believe him,如果主句是一般将来时,从句往往用一般现在时来表示将来,如：I’ll go for a picnic if it is fine. 4.结果状语从句 一般由so...that, such...that引导,如：It’s such a heavy box that nobody can move it. The box is so heavy that nobody can move it.
