2、状语从句的分类:时间状语从句、地点状语从句、条件状语从句、原因状语从句、结果状语从句、比较状语从句、目的状语从句、让步状语从句、方式状语从句二、状语从句考点纵览考点一:时间状语从句考点1:when, as和while引导的时间状语从句。

① when, as和while引导时间状语从句均表示“当……时候”。

典型例句It was raining hard when I got to school yesterday.While he was doing his homework, the telephone rang.As he walked along the lake, he sang happily.②时间状语从句引导词while, when和as的区别。

◆when既可以指“时间点”,与瞬间动词连用,也可以指“时间段”,与延续性动词连用(=while)。

如:When he came in, his mother was cooking.When (While) we were at school, we went to the library every day.◆while表示时间段,因此,while从句的谓语动词要用延续性动词。

另外while 还可以表示对比。

如:Please don't talk so loud while others are working.Tom’s brother was playing the computer games while Tom was studying hard.◆as与when用法相似,但着重强调主句动作与从句动作同时发生,有“随着……”或“一边……一边……”之意。

As you get older, you get more knowledge.考点2:before“在……之前”和after“在……之后”引导的时间状语从句。

典型例句He had learned a little Chinese before he came to China.After he had finished middle school, he went to work in a factory.考点3:until/till“直到……”引导的时间状语从句。

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。

典型例句The young man read till the light went out.Let’s wait until the rain stops.We won’t start until Bob comes.Don’t get off until the bus stops.考点4:as soon as“一……就……”引导的时间状语从句。

As soon as I arrive, I will call you.He will be happy as soon as he thinks of his childhood.考点5:since“自从……”引导的时间状语从句。

since引导时间状语从句,表示主句的动作,从过去的某一点时间持续到现在,从句时态常用一般过去时,主句的时态一般用现在完成时。

典型例句He has not written to me since he graduated from high school.We have known each other since we came to the school two years ago. 。

考点6:在时间状语从句里,通常不用将来时态,用现在时态表示将来的动作或状态。

典型例句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.考点1:条件状语从句通常由if“如果……”, unless“除非……”引导。

考点二:条件状语从句典型例句What shall we do if it snows tomorrow?Don’t leave the building unless I tell you to.考点2:在条件状语从句里,谓语动词通常用现在时态表示将来的动作或状态。

典型例句I’ll help you with your Engli sh if I am free tomorrow.He won’t be late unless he is ill.考点3:“祈使句+ and (or)+ 陈述句”在意思上相当于一个带有条件状语从句的复合句。

典型例句Hurry up, or you’ll be late.=If you don’t hurry up, you’ll be late.Study hard and you will pass the exam.=If you study hard, you will pass the exam.考点1:地点状语从句常常由where来引导。

考点三:地点状语从句Go where you like.Where there is a will, there is a way.考点1:原因状语从句通常由because, since, as和for引导。

考点四:原因状语从句典型例句He didn’t come to school because he was ill.As it is raining, we shall not go the zoo.Since you can’t answer the question, I’ll ask someone else.He could not have seen me, for I was not there.考点2:because,as,since和for 的区别。

because用于表示直接原因,回答why提出的问题,语气最强;as用于说明原因, 着重点在主句,常译成“由于”;since表示显然的或已知的理由或事实,常译成“既然”;for表示原因时,只能放在主句之后,起到补充说明的作用。

典型例句---Why didn’t you go there? ---Because I didn’t want to.Water is very important because we can't live without it. He didn't come yesterday as his mother was ill. 。

I'll do it for you since you are busy.It must have rained last night, for the ground is wet.考点3:because和so不能同时在一个句子中出现。

Because he spends little time learning English, he fails in the exam.=He spends little time learning English, so he fails in the exam.考点五:结果状语从句考点1:结果状语从句由so…that, such…th at, so that引导。

典型例句He is so poor that he can’t buy a bike for his son.She is such a good teacher that everybody likes her.My pencil fell under the desk, so that I couldn’t see it.考点2:so…that与such...that可以互换。

①在so...that引导的结果状语从句中,so是副词,与形容词连用。

其结构是: “...so + 形容词(副词)+ that + 从句”。

典型例句He was so glad that he couldn’t say a word.The hall is so big that it can hold 2,000 people.Mother lives so far away that we hardly ever see her.②在such…that引导的结果状语从句中,such是形容词,它修饰名词。

其结构是:“...s uch + a/an+形容词+可数名词单数+ that + 从句”、“...s uch +形容词+可数名词复数+ that + 从句”和“...s uch +形容词+不可数名词+ that + 从句”典型例句It was such a hot day that nobody wanted to do anything.He had such long arms that he could almost touch the ceiling.He made such rapid progress that he did very well in the mid-term exams.③有时上述两种结构是可以互换的。

典型例句It was such a wonderful film that all of us wanted to see it again.=The film was so wonderful that all of us wanted to see it again.It is such an important match that nobody wants to miss it.=The match is so important that nobody wants to miss it.考点3:如果名词前由many, much, little, few等词修饰时,只能用so, 不用such。

典型例句There were so many deer that they ate up all the wild roses. He has so little time that he can’t go to the cinema with you.考点六:目的状语从句考点1:目的状语从句通常由so that, in order that引导。
