13、l,since,as soon as,now that,hardlywhen,scarcelywhen,no soonerthan,有一些表示时间的副词（短语）或名词短语也可引导时间状语从句。如：directly,instantly,immediately,by the time，the moment,the second,the minute,the instant,every time,each time,next time,the last time等重点内容如下：when,while,as引导的时间状语从句as表示“当的时候”，往往和when/ while通用，但它着重强调主句与从句的

14、动作或事情同时或几乎同时发生。She came up as I was cooking.(同时)The runners started as the gun went off.(几乎同时)when(at or during the time that )既可以表示在某一点的时候，又可表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。It was raining when we arrived.(指时间点)When we were at school, we went to the library every day.(在一段时间内)When we arrived there

15、,the film had already begun.(先后发生)while意思是“当的时候”或“在某一段时间里”。主句中的动作或事情在从句中的动作或事情的进展过程中发生，从句中的动词一般要用延续性动词。在when表示a period of time时，两者可以互换。Please dont talk so loud while/when others are working.He fell asleep while/when reading.Strike while the iron is hot.( 不可用as或when，这里的while意思是“趁”)before状语从句的重点句型之后才：

16、It was a long time before I got to sleep .不多久就：It wasnt long before he told me about the affair.不等就：Before I could get in a word, he had measured me.刚就：He hardly entered the room before he heard the telephone ring.先再：You can have a few days to think about it before you make your decision.since 引导的从句

17、用延续性动词的过去式（包括过去完成时），则从句的动作已经结束,从句意思是否定的。如果从句的动词是延续性的用完成时态，从句意思是肯定的。He has never been to see me since I was ill.我病愈后，他一直未来看我。（不在生病了）He has never been to see me since I have been ill.我病了，他一直未来看我。I havent heard from him since he lived here.自从他这里搬走，我就没有收到他的信。（不住在这儿了）I know him very well since he has liv

18、ed here near us.自他住在我们附近以来，我对他很了解。Its three years since I was in the army.我退伍已三年了。（不在服役了）Its three years since I have been in the army=It's three years since he joined the army.我入伍已三年了。如果与till与until从句使用的主句是肯定的，则主句中谓语要用延续性动词如果与其使用的主句是否肯定的，则主句中谓语要用短暂性动词。另till从句不可以置于句首，只有until从句可以放在句首。not until 放在句

19、首时主句要倒装。2.原因状语从句由下列连词引导：as（由于）,because(因为), since（既然）,now (that) (既然), considering that（顾及到）, seeing that（由于）。I do it because I like it.因为我喜欢我才干。(because不能与 so连用)He couldnt have seen me, because I was not there.他不可能见过我，因为当时我不在那儿。Seeing (that) quite a few people were absent, we decided to put the mee

20、ting off.由于好些人都没到会，我们决定延期开会Now that/Since you are all here, lets try and reach a decision.既然大家都来了咱们就设法做一个决定吧As she was ill, she didnt come to the party.由于病了，她没来参加晚会。Considering that they are just beginners, they are doing quite a good job.考虑到他们才刚刚学做，他们干得算很不错的了。重点内容如下：because语气最强，用于回答why的提问，可与强调词only

21、,just 以及否定词not 连用。但不可以与so连用。如You shouldnt get angry just because some people speak ill of you.另外注意与not连用时否定的转移。He didnt do such a thing because he was afraid of his wife.他并不是因为怕他的妻子才做这样的事。Cf:He didnt do such a thing,because he was afraid of his wife.因为怕妻子，他没有做这样的事。because引导的从句可以被强调：It was because sh

22、e wanted to study abroad that she entered for TOEFLas语气较弱，since语气也较弱，但比as正式一些,所说明的原因比较明显或是已知的事实，多用于口语中，所以不应该强调。常置于句首。As all the seats were full,he stood there.Since you are going,Ill go,too.for虽解释为“因为”但只是一个并列连词，它引导的是并列句，不是原因状语从句。The day was short,for it was December.3.地点状语从句由下列连词引导:where,wherever,an

23、ywhere,everywhere。Anywhere he went,he got warm welcome.

24、的从句不是定语从句)4.结果状语从句由下列连词引导：that，sothat，so that（从句中不带情态动词），suchthat，with the result that等。注意以下几种结构：so+adj/adv+that                        such(a/an+adj)+n+thatso+adj+a/an+n+that=such a/an

25、+adj+n+that  so many/much/few/little(少)+n+that注意以上结构与定语从句so/suchas的区别。This is such an interesting/so interesting a film that/as everyone wants to see it/(it).He didnt plan his time well so that/so he didnt finish the work in time.他没把时间计划好，结果没按时完成这项工作。We left in such a hurry that we forgot to lo

28、语动词常与情态动词can, could, may, might, should连用。（so that也可用来引导结果状语从句，但从句中不带情态动词）Lets take the front seats (so) that we may see more clearly.我们坐前排吧，这样我们看得更清楚些。School was closed early in order that the children might go home ahead of the storm.早点儿放学是为了让孩子们在暴风雨到来之前回家。He took the name down for fear that he sh

29、ould forget it.他把名字写下省得忘了。（该从句中一般用情态动词should+动词原形，或省略should）Better take more clothes in case the weather is cold.最好多带些衣服以防天气会冷。注意：so that引导的目的状语从句只能放在主句之后，in order that 引导的目的状语从句可以放在主句之前或之后。6.条件状语从句分为真实条件句和非真实条件句（用在虚拟语气中）。表示条件的状语从句可以由if（如果）,unless（除非）, in case（万一）, so /as long as（只要）, as/ so far as（

30、就而言）, on condition that（条件是）suppose（假设）supposing（假设）（仅用在问句中）等词或词组引导。一般情况下当主句是将来时的时候，从句要用一般现在时。As/So long as we dont lose heart, well find a way to overcome the difficulty.只要我们不灰心，我们就能找到克服困难的方法。Send us a message in case you have any difficulty.万一你有什么困难，请给我们一个信儿。If you leave at 6 oclock tomorrow morni
