1、状语从句【导学线索】解状语从句“三部曲”第一步：弄清主从句的逻辑关系。第二步：辨析连接词的语义和语用特征。第三步：据逻辑关系选出适当的连接词。【导学目标】1】 了解状语从句的常见连词2】 能够辨析常考的状语从句连词。基础知识时间状语从句一， when, while, as1,when既可以引导一个持续动作，也可以引导一个短暂动作，可用于主句和从句动作同时发生或从句动作先于主句动作。如：When I lived there, I used to go to the seashore on Sundays.When the movie ended, the excited people didnt

2、 want to leave.当when引导的时间状语从句为系表结构，而且其主语和主句的主语一致，其表语又是一个名词时，就可以用以as引导的省略句来代替when引导的从句。如：As a young man(=when he was a young man), he was fond of hunting.2,while引导的动作必须是持续性的动作侧重主句动作和从句动作相对比。如：Please dont talk so loud while others are working.3,从属连词as可表示从句和主句两个动作交替进行或同时完成，可译为“一边,(一边)”或“随着”。如：He hurrie

3、d home, looking behind as he went.As time went by, it became warmer and warmer.随着时间的流逝，天变得越来越暖和了。4，when还可以做并列连词，其意义为“在那时，在这时”，相当于and at this/that time.常用于下列句式：Somebody was doing something when.Somebody was about to do/ going to do/ on the point of doing something whenSomebody had just done something

4、 when如：We were having a meeting when someone broke in.We were about to set off on our way when it suddenly began to rain.此外when还表示原因，“既然”。如：It was foolish of you to take a taxi when you could easily walk there in five minutes.5,while 作为并列连词，意为“而，却”，表示对比。如：He likes pop music, while I am fond of folk

5、music.6,如果主句表示的是短暂性的动作，而从句用延续性动词的进行时态表示在一段时间内正在进行的动作时，when while as 可互换使用。如：When/while/as I was walking down the street, I came across an old friend of mine.（ ）I was walking down the street, I noticed a police car in front of the store.二， as soon as, immediately, directly, instantly, the moment, the

6、 minute, the instant, once(一就.)这些从属连词引导的从句都表示从句的动作一发生，主句的动作随即就发生，常译为“一.就.”从句中用一般时态代替将来时态。如：The moment I hear the voice, I know father is coming.The boy burst into tears immediately he saw his mother.注意：no sooner than.; hardly/ scarcelywhen这一结构的时态搭配；no sooner与hardly/ scarcely引导的句子谓语动词应该用过去完成时，而than与w

7、hen引导的句子谓语动词应该用一般过去时。此外，当把no sooner和hardly/scarcely提到句首时，应用倒装语序。如：I had hardly got home when it began to rain.Hardly had I got home when it began to rain.三：till, until和not until1,肯定句：主句谓语动词必须是延续性动词，主句，从句都为肯定式，意为“某一动作一直延续到某时间点才停止”。如：He remained there until she arrived.You may stay here until the rain

8、 stops.2,否定句：主句谓语动词必须是非延续性动词，从句为肯定式，意为“某动作直到某时间才开始”。如：He wont go to bed till/ until she returns.3,till不可以至于句首，而until可以。如：Until you told me I had no idea of it.4, notuntil句型中的强调和倒装用法：It was not until you told me that I had any idea of it（强调句）Not until you told me did I have any idea of it.(not until置

9、于句首，主句要倒装)句型转化：I didnt leave until she came back._ _she came back_ _ leave._ _not until she came back_ I _.四Before 和since1,若表达“还未.就.;不到就. ; .才; 趁；还没来得及”时，需用连词before。如：We had sailed four days and four nights before we was land.We hadnt run a mile before he felt tired.2, it will be/ was+一段时间+before.多久

10、之后才.。如：It wasnt long before we met again.3,since从句的谓语动词一般是非延续性动词，主句的谓语动词是延续性的或者是反复发生过的动作。Since从句的时态若是一般过去时，相应的，主句的时态是现在完成时或现在完成进行时。如：I have written home four times since I came here.She had been working in this factory since she left school.4,在“it is+一段时间+since从句”句型中，时间的计算一律从since从句的动作完成或状态结束时算起。如：I

19、，之后，而so that引导的状语从句只能置于主句之后。如：Ill speak slowly so that you can understand me.In order that we might see the sunrise, we started for the peak early.2, for fear that, in case这些从属连词引导的目的状语从句中谓语动词要用（should+）动词原形，它本身带有否定意义、相当于so that.not或in order that.如;The boy hid himself behind the tree in case/ for fe

20、ar that his father should see him.Take your raincoat in case it should rain.三， 结果状语从句1，引导结果状语从句的连词有： so that, sothat, suchthat。在非正式语体中，由sothat, suchthat引导的句子中that可以省略，注意其结构形式： So+形容词/副词+that从句 So+adj+a/an+可数名词单数+that从句 So+many/much/few/little(少)+名词+that从句 Such+a/an+adj+可数名词单数形式+that从句 Such +adj+可数名词

(虚拟语气)2， as 引导的让步状语从句需倒装。As从句一般放在主句之前，需用倒装语序。从句中的表语，状语或动词原形置于句首。若表语是单数名词，前置时要省略冠词。如：Child as he is, he knows a lot.Much as I like it, I wont buy it, for

32、 so/as+ 形容词/副词+(名词)+ as+被比较对象” 这个句型。You are not so old as you look.There was no garden so lovely as his in this city.It isnt as cold as it was yesterday.有时as好像是从句的主语，其实是从句的主语省略了。There were not so many tickets available as were asked for.比较句的肯定形式还有the same as, suchas, 否定形式还有not the same as, not sucha

33、s.Your name is the same as your fathers.I never met such a man as your younger brother.2,主语+谓语+形容词/副词的比较级+than+被比较对象在这种结构中than是个连词，引导比较状语从句，如果被比较的对象为名词或代词，一般采用省略形式，省去与主句相同的部分。This river is longer than that one.She studies more diligently than her classmates.有时，连词than后直接跟从句的谓语，这时我们可以把它看成是省略了某些词语。She

34、played the piano much better than could have been expected.There were more casualties than was reported. (=than it was reported there were)在这种结构中，有时比较对象需要根据上下文内容进行判断； 有时对象含蓄在主句中，这时后面往往是一个表示时间或条件的修饰语。Taking this medicine helps to relieve his headache, and makes him less ill-tempered than before.Than

35、he no one could show a friendlier attitude to you.3,主句+谓语+形容词/副词最高级+（名词）+范围在这个句子结构中，形容词最高级前面要加定冠词the， 副词最高级的前面可加the，可不加。 形容词最高级后面可跟名词，而副词后面却不能跟名词，他只能修饰动词，比较范围一般是短语或从句。This coat is the most expensive that Ive ever bought.She bought the least expensive towels that she could find.最高级还可以用以下结构表示否定词语+ 比较级

37、 fast as any other student in the class.The river is as long as any other in the world.4, the+比较级， the+比较级这是表示比例的句型，意思是“越，就越”，后面跟的是形容词或副词的比较级。通常前面为条件状语从句，后面为结果主句。The more, the better.The sooner, the worse.The more you work, the greater progress you will make.主句的主谓有时半倒装，以保持句子的平衡。The more you read, th

38、e better will you write.5,类比句，表示两类事物的相同或相似关系，通常用连词引导从句，其主要句型是1）A is to B what/as C is to D.Reading is to the mind what exercise is to the body.2) A does for B what C does for D.Leaves do for plant what lungs do for animals.3) A is that to B which C is to DIntellect is that to mind which sight is to

39、the body.4) A does that for B which C does for D.Railways do that for a country which blood vessels do for a mans body.状语从句的省略现象当主从句的主语一致，从句的谓语部分有be，或者从句是it is/was时，可以省去从句中的主语和be动词或it is/ was.一， 时间状语从句中常见的省略。While in Beijing, I paid a visit to the Summer Palace.As a young man, Abraham Lincoln was a
