1、状语从句知识复习相关要点要点一：英语状语有哪些种类，英语状语的分类英语中的状语按其用途，可以分为时间状语、地点状语、方面状语、 原因状语、结果状语、目的状语、条件状语、让步状语、程度状语、 方式状语、伴随状语等11种。一、时间状语She is to be married next month.她预定在下个月 结婚。Ill meet you at 4 oclock.我将在4点钟和你见面。A lot of students missed my lecture yesterday.昨天许多学生误 了我的 课。二、地点状语He lives over the mountain.他住在山的那一边。I fi

2、rst met him in Paris.我初次见到他是在巴黎。The children are swimming in the river.孩子们正在河里游泳。注：地点状语除表位置外，还可以表“出发”“去向”“距离”等。如：Are you glad to be going back to school?返回学校你感到高兴吗？ They lived many miles from the town.他们住的地方离镇子好几英里 远。三、方面状语She is very weak in physics.她物理很不行。China is very rich in natural resources. 中

3、国自然资源丰富。This is better in every way than that.这个在哪一方面都比那个要好。You will be late you leave immediately.A. unless B. until C. if D. or答案A。句意：除非你立即走，否则你就回迟到的。可转化为If you dong leave immediately, you will be late. B、D 句意不对，or 表转折， 句子如为 You leave immediately or you will be late.要点十：让步状语从句though, although注意：当有

4、though, although时，后面的从句不能有but,但是though 和yet可连用Although its raining, they are still working in the field. 虽然在下雨，但 他们仍在地里干活。He is very old, but he still works very hard.虽然他很老，但仍然努力 地工作。Though the sore be healed, yet a scar may remain.伤口虽愈合，但伤疤 留下了。（谚语） 典型例题1.she is young, she knows quite a lot.A. When

5、 B. However C. Although D. Unless答案：Co意为虽然她很年轻，却知道许多。2）as, though引导的倒装句as/though引导的让步从句必须表语或状语提前（形容词、副词、分词、实义动词提前）。Child as /though he was, he knew what was the right thing to do.=Though he was a small child, he knew what was the right thing to do.注意：a.句首名词不能带任何冠词。b.句首是实义动词，其他助动词放在主语后。如果实义动词有宾语 和状语，

6、随实义动词一起放在主语之前。Try hard as he will, he never seems able to do the work satisfactorily.=Though he tries hard, he never seems-虽然他尽了努力，但他的工作总做的不尽人意。3)ever if, even though.艮fl 使Well make a trip even though the weather is bad.4) whetheror- 不管者EWhether you believe it or not, it is true.5)no matter +疑问词或疑问词

7、+后缀everNo matter what happened, he would not mind.Whatever happened, he would not mind.替换：no matter what = whateverno matter who = whoeverno matter when = wheneverno matter where = whereverno matter which = whicheverno matter how = however注意：no matter不能引导主语从句和宾语从句。（错） No matter what you say is of no

8、 use now.（对）Whatever you say is of no use now.你现在说什么也没用了。（Whatever you say是主语从句）（错）Prisoners have to eat no matter what theyre given,（对）Prisoners have to eat whatever theyre given.囚犯们只能给什么 吃什么。要点十一：比较状语从句比较状语从句常用 than, so （as） . as, the more . the more 等引导。I feel better now than （I was） before.我现在觉得

9、比以前好了。He writes as well as you （do）.他写得和你一样好。This problem is more difficult than that one （is）.这道题比那道题难。要点十二：比较until和till此两个连词意义相同。肯定形式表示的意思是“做某事直至某时“，动 词必须是延续性的。否定形式表达的意思是直至某时才做某事”。动 词为延续性或非延续性都可 以。正确使用这两个连词的关键之一 就在于判断句中的动词该用肯定式还是否定式。肯定句：I slept until midnight.我一直睡到半夜时醒了。Wait till I call you.等着我叫你。

10、（在肯定句中可用 before 代替 Lets get in the wheat before the sun sets.）否定句：She didnt arrive until 6 oclock.她直至ll 6 点才至U。Dont get off the bus until it has stopped.公共汽车停稳后再下车。I didnt manage to do it until you had explained how.直至ll你教我后，我 才会做。l)Until可用于句首，而till通常不用于句首。Until you told me, I had heard nothing of w

11、hat happened.直到你告诉我以前，出了什么事我一点也不知道。2)Until when疑问句中，until要放在句首。Until when are you staying? 你呆到什么时候？-Until next Monday. 呆到下周一。注意：否定句可用另外两种句式表示。(1) Not until在句首，主句用倒装。Not until the early years of the 19th century did man know what heat is.直到19世纪初，人类才知道热能是什么。Not until I began to work did I realize how

12、much time I had wasted.直到我开始工作，我才认识到了我已蹉跖了几多岁月。(2) It is not until* that要点十三：表示 一就”的结构hardly/scarcely when/before, no sooner-than 和 as soon as 都可以表示一就的意思,例:I had hardly / scarcely got home when it began to rain.I had no sooner got home than it began to rain.As soon as I got home, it began to rain.注意

13、：如果hardly, scarcely或no sooner置于句首,句子必须用倒装 结构：Hardly / Scarcely had I got home when it began to rain.No sooner had I got home than it began to rain.要点十四：if引导的条件状语从句结构：if+一般现在时，主语+将来时含义：如果，将要例如：If you ask him, he will help you.如果你请求他，他会帮助你。If need be, we 11 work all night.如果需要，我们就干个通宵。要点十五：when、while

14、as引导时间状语从句的区别这三个词的意思很简单，都有“当时候”的意思。一、when的用法如果只从现象来看，when从句用的最多的是一般过去时，而主句的 时态没有限制，根据具体情况而定。When he was a child he was always trying out new ideas.他小时候就常常试验一些新的设想。 when she came into my room I was just reading a book.她走进我房间时，我正在看书。Were you writing when the teacher came in?老师进来的时候，你在写信吗？Sorry, I was

15、out when you called me.对不起，你打电话来的时候我出去了。He was on the point of leaving when someone knocked at the door.他正要走，这时有人敲门。I thought of it just when you opened your mouth.就在你要说话的时候，我也想到了。I had hardly scarcely closed my eyes when someone knocked at the door.我刚一闭上眼，就有人在敲门了。根据以上的例句，我们可以总结出一点：when从句的A事件，相当 于另一

16、个事件B发生的时间点。也就是说，when从句的重点不在动 作本身发生的状态，而只是把它作为一个时间点，所以when多数情 况下用的是一般过去时，则不用正在进行时。因为如果用正在进行时, 它表示的就是一段时间而不是一个时间点了。根据这一点，有的文章 补充说：when从句的动词大多是瞬时动词。这种说法也可以参照。 实际上，when从句也可以有其它的时态，但几乎也不用进行时，因 为它也只是作为一个时间参照点。例如：When I got to the airport, the guests had left. 当我赶到飞机场时，客人们已经离开了。When he had finished his hom

17、ework, he took a short rest.当他完成作业后，他休息了一会儿。Why do you want a new job when you have got such a good one already ?你已经找到如此好的工作，为何还想再找新的？You shall borrow the book when I have finished reading it.在我读完这本书后，你可以借阅。When the manager comes here for a visit next week, Ill talk with him about this.下周，经理来这参观时，我会

18、和他谈谈此事。 二、while的用法相比于when来说，while从句的侧重点就不一样了。while从句的 侧重点在于描述动作正在发生的状态，它的意思是：当while事件正 在发生的时候，另一件事如何如何。所以，while从句一般用的是正 在进行时。而另一件事的状态没有硬性的要求，根据具体情况而定。 例如：While my wife was reading the newspaper, I was watching TV.当妻子正在看报纸的时候，我正在看电视。While Jim was mending his bike, Lin Tao came to see him.正当吉姆修自行车时，林涛

19、来看他。While they were talking , the bell rang.正在他们谈话的时候，上课铃响了。You cant do your homework while youre watching TV.你不能一边看电视一边做家庭作业。While John was sitting biting his nails, I was working out a plan to get us home.约翰坐在那里咬指甲时,我想出了一个回家的办法。从时间的角度来看，while表示的是一段时间，是一个过程。这是 while的侧重点。因此，如果含有“一段时间”的含义的时候，就可 以用whi

20、leo例如：Strike while the iron is hot.趁热打铁。这句话中，是说趁着铁是热的这段时间，赶紧打铁。如果换成when 意思就变了，相当于说铁只热了一下，打一下，然后铁就冷了。这显 然不符合文意。再例：一Im going to the post office.一While youre there, can you get me some stamps?三、as的用法Kas从句表示的也是一件事情正在发生，另一件事也正在进行当中。 但与while从句不同的是，as从句用的一般不用正在进行时，而只 是一般过去时。as从句一般可以翻译成“边边”。例如： As my mother

21、 sang those old songs, tears ran down her cheeks. 当我妈妈唱起那些老歌时，眼泪顺着她的脸颊流了下来。The students took notes as they listened.学生们边听课边做笔记。As we talked on, he got more and more excited. 我们继续往下谈的时候，他越来越兴奋。The little girls sang as they went.小姑娘们一边走，一边唱。Just as he caught the ball, there was a tearing sound.当他抓住球的时

22、候,有一种撕裂的声音。2、as表达的事件，往往只是主句动作发生的背景或条件时，as只 是一个次要的时间说明，不像while从句有强调while动作本身的意思。因此，as常常翻译成“随着”之意。例如：As the time went on, the weather got worse.随着时间的推移，气候更加糟糕。The atmosphere gets thinner and thinner as the height increases.随着高度的增加，大气越来越稀薄。As years go by, China is getting stronger and richer.随着时间一年一年过去

23、，中国变得越来越富强了。3、少数情况下，如果强调动作正在发生，as从句也可以用正在进行 时。这只能算是特例了。The sad mother sat on the roadside, shouting as she was crying.伤心的妈 妈坐在路边，边哭边叫。As we was going out, it began to snow.我们出门时，开始下雪了。He came in as I was going to bed.正要上床睡觉，他进来了。要点十六：as long as和so long as引导条件状语从句的区别 as long as和so long as均可表示“只要，用于引导

24、条件状语从句， 两者没什么区别。如：I dont care so as long as she lets me be with her son,只要她让我和她 儿子在一起，我不在乎。You can take my car as so long as you drive carefully.你可以用我的 汽车，只要你小心点儿开。You may use my dictionary as so long as you dont keep it too long. 只 要使用时间不太长，你可以用我的词典。但是，当as long as用于本义表示“与一样长”时，与so long as在用法上是有区别的，

25、即as long as可用于肯定句或否定句，而so long as只用于否定句，不用于肯定句。如：It took three times as long as I had expected.这件事比我预料的多花了 两倍的时间。It didnt take as so long as I expected.花的时间比我预料的短。要点十七：“as”作连词的用法as作连词1 .当的时候He rose as she entered.当她进来的时候，他站了起来。2 .因为As Davidson had a passion for walking, we started off on foot.The br

26、idge is 2500 meters in length and 150 meters in height.这座桥长2500米,高150米。四、原因状语He was surprised at what she said.听到她说的话，他很吃惊。He succeeded by hard work.他由于努力工作而成功。He was sent to prison for robbery.他因为抢劫而坐牢。Last week she fell ill from cold.上星期她着凉生病 了。Were proud of our motherland.我们为祖国感至U骄傲。五、结果状语He talk

27、ed his wife into buying a car.他说服他妻子买一辆小汽车。The box is too heavy for me to lift.这个箱子太重 了，我提不动。It rained heavily, causing severe flooding in that country. 大雨滂沱，造 成了那个国家洪水泛滥。He went to Africa in 1963, never to come back.他在 1963 年到非洲,然 后就再也没回来过了。六、目的状语They went out for a walk.他们出去散步 了。He saves on behalf

28、 of his son.他为儿子存钱。He stood aside for her to pass.他靠边站让她过去。He cupped his ear to hear better.他的手捂着耳朵，以便听得更清楚。He went to the south in search of a better life.他去南方寻求更好的生 活。因为戴维逊很想走走路，所以我们就步行启程了。3 .既然As you are sorry, Ill forgive you. 既然你有认错之意，我就原谅你啦。4 .按照I have changed it as you suggest.我按照你的建议作了一些修改。5

29、 .像Do as I do it.像我作的方法再作一下。6 .正如As he knew, she wasnt much at letter-writing.正如他所知道的，她不太善于写信。这里举的例子都是as接状语从句。要点十八：unless和if not引导的否定条件句两者都可表示否定的条件，有时可换用。如：Come tomorrow unless I phone if I dont phone.要是我没有打电话， 明天就来。You wont catch the train unless you hurry if you dont hurry. 你要是不 赶快，你就赶不上火车了。但是在下列情

30、况下，通常要用if .not而不用unless：1 .当从句所引出的情况不是表示主句情况发生的一种例外而只是一种可能，并且这种可能正是导致主句情况发生的主要原因时，英语习 惯只用if.not,不用unlesso如：Ill be surprised if he doesnt win.如果他不赢，我会感到惊奇。Shed look nicer if she didnt wear so much make-up.要是她不过分打 扮，本来会更好看的。Ill be sorry if they do not come tomorrow.如果他们明天不来，我将感 到非常遗憾。2 .当从句内容与已知事实相反时（

31、即引出虚拟条件时），通常要用if.not,而不用 unlesso 如：If he werent so silly, he would understand,他要不是那样傻的话，他就 会明白了。（实际上他很傻）If I hadnt stopped her, she would have jumped down.要不是我阻止了 她，她就跳下去了。（实际上我阻止了她）unless有时可引出一个过去未曾实现的假想法情况，对前面主句进行 补充说明（此时必须置于主句之后，且前面常用破折号而不用逗号）。如：I couldnt have got to the meeting on time一unless I

32、had caught an earlier train.我不可能及时赶到会场，除非我赶上了较早一班火车。（事实 是“我”没有及时到会）此句若将unless改为if.not,则成为:I couldnt have got there If I hadnt caught an earlier train.如果我没赶上 较早一班火车，我就不能到达那儿了。（事实是“我”及时到会了）要点十九：主将从现规则主将从现六种情况：1 .如果主句是将来时或表示将来含义时，那么条件和时间状语从句 多用一般现在时。2 .如果主句是祈使句，那么从句通常要用一般现在时。3 .如果主句是含有情态动词的一般现在时，根据需要从句

33、多用一般 现在时。4 .如果if的条件状语从句遇到变换间接和直接时，祈使句应用notto5 .主将从现说的是在含有时间状语从句和条件状语从句的主从复合 句中，如果主句的时态是一般将来时，那么从句要用一般现在时。6 .如果主句的时态是过去将来时，那么从句要用一般过去时。If he comes, give him the picture.（主句是祈使句，关键句是一般现在时） If we try our best, well get good grades.r 11 telephone you as soon as I get there.我一到达那里就打电话给你。 She said she wou
