2、同时发生的，或从句的动作发生在主句的动作之前；while 表示的时间是一段，而不是一点，as 多用在口语中，强调“同一时间”或“一前一后” ，有时还有“随着”的含义。Ill go on with the work whencome back tomorrow我明天回来后会继续做我的工作。When spring came, he felt like a trip.春天来了，他想去旅游。When he was eating his breakfast, he heard the doorbell ring.(强调吃饭的时候） 。While he was eating his breakfast,

15、句引导原因状语从句的连词有：because, for, since, as, now that 1) because 意为“因为” ，表示直接的原因或理由，着重点在从句，用于回答 why，语气最强。He is absent today because he is ill. 他今天缺席，因为他病了。I didnt go out because I was busy with homework. 我没有出去，因为我忙于家庭作业。有时，可用 because of 后接名词或代词表示原因，此时 because of=for(介词)。We wont be able to come because of

16、the weather. 由于天气的原因，我们来不了。She was looking all the better for her stay in hospital. 她因为待在医院，显得好多了。2) for 意为“因为” ，引导的从句并不说明主句行为发生的直接原因，只提供补充说明，且不可位于主句前。for 前往往用逗号或分号与主句分开，引起的从句对主句加以解释。I didnt go to see him, for a heavy snow was falling. 我没有去看他，因为在下大雪。The days were short, for it was now December. 白天短了

17、，因为现在已经是十二月了。We must begin planning now, for the future may bring unexpected changes.我们必须现在就开始筹划，因为将来可能会发生意想不到的变化。有时，for 引起的从句并不表示原因，而是表示一种推断或解释，而 because 则不能。Someone in the house must be ill, for a doctor has just come out.房子里一定有人病了，因为有个医生刚刚出来。3) since 意为“既然” 、 “由于” ，一般表示对方已知的、无需加以说明的既成事实的理由(如果从句表示

18、的原因不是确定的事实，就不能用 since，通常用 because)。Since you are going, I will go too. 既然你要走，我也走了。Since you are ill, Ill go alone. 由于你病了，我就一个人走了。4) as 意为“由于” ，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。As it is snowing, we shall not go to the park. 由于正在下雪，我们就不去公园了。He had to apologize, as he knew he had made a mistake. 他必须道歉，因为

19、他知道他错了。5由 as 表示的原因语势最弱，常用于口语。5) now that 意为“既然” ，有时可将 that 省去，含义与 since 接近。区别在于：since 表示原先已存在的情况，而now that 表示现在才发生的情况。Now that it has stopped raining, lets start at once. 既然现在雨停了，咱们马上开始吧！Now that you have come, you may as well stay. 既然来了，你最好还是待在这儿。2地点状语从句引导地点状语从句的连词有： where, wherever, anywhere, ever

20、ywhere Put it where you can see it. 把它放在你看得见的地方。Ill find him, wherever he is. 不管他在哪里我都要找到他。You should put the book where it was.你应该把书放在原来的地方。Wherever you go, you should do your work well. 不论你到哪里都要把工作做好。You cant camp anywhere/where/ wherever you like.你不能想在哪里安营就在哪里安营。针对性练习1 参照例句，用所给的原因状语从句连词将方框 1 和方框
