(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, I’ll ring you up as soon as I get to New York. I will tell him everything when he comes back. He won’t believe it until he sees it with his own eyes.. (3)when和while都表示"当........的时候",但有区别. when强调"特定时间",如: It was raining hard when got to school yesterday. while表示的时间是一段,而不是一点,如: While he was doing his homework, the telephone rang. while有时还有对比的含义,如:While I was reading, he was writing. (4)在带有till或until引导的时间状语从句的主从复合句里,如果主句用肯定式,其含义是"一直到....时",谓语动词只能用延续性动词.如果主句用否定式,其含义是"直到....才....","在....以前不....",谓语动词可用瞬间动词. I’ll read the book until she comes back. I’ll not come back until she goes home. 2、原因状语从句 (1)常由because, since, as, for等引导. (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,中心在主句,语气比because弱,常译为"既然" 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" 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" You haven't met him, for he didn't come here. 3、条件状语从句 (1)常由if(假如、如果)、no matter(不管)、unless(除非)来引导; No matter what he says, I won't believe him. What shall we do if it snows tomorrow? Don’t leave the building unless I tell you to. (2)在条件状语从句里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; I'll go for a picnic if it is fine. I’ll help you with your English if am free tomorrow. He won’t be late unless he i
