1、专题14 【状语从句】解题指导触类旁通寻方法，求策略，掌握“套路”1确定是状语从句设空前后两个句子之间含有一定的逻辑关系时，应用状语从句的引导词。2两个关键点突破状语从句(1)重点关注几组引导词用法原因状语从句as, because, since, now that地点状语从句where, wherever目的状语从句so that, in order that, for fear that, in case结果状语从句so that, so . that ., such . that .条件状语从句if, unless, so/as long as, in case让步状语从句though/

2、although/while, as, even if/though, however, whether . or ., whatever, whoever, no matter how/what/which(2)利用时间先后法巧定时间状语从句引导词动作同时发生： when、 whenever、 while、 as等。动作接连发生： as soon as、 the minute、 immediately、 once等。先后发生： before、 after等。动作的延续： since。动作的终止或开始： till/until。3状语从句易错点：such . that . 结构中such修饰名词

3、；so . that .结构中so修饰形容词或副词。somany/much/few/little(少)名词that .the moment/the instant/every time/immediately 等相当于连词，引导时间状语从句，不能与when连用。not . until中的not可能换为never, no等表否定的词构成陷阱。4.析三大从句，辨七大易混点易混点(一)定语从句和并列句1She has many novels, some of _ are interesting.2She has many novels, and some of _ are interesting.分

4、析 1.whichwhich引导定语从句，修饰先行词novels, “some of which”在从句中作主语。2them此句为and引导的并列句。点拨定语从句与并列句的主要区别：句中若有and, but, so等并列连词或分号则为并列句，此时不需要再填引导词。易混点(二)定语从句和状语从句1.We young people should go to the place _ is in need of help.We young people should go _ were most needed.分析which/that关系代词which/that引导定语从句，修饰先行词“the pla

5、ce”，且在从句中作主语。wherewhere引导地点状语从句，修饰主句谓语动词go。点拨定语从句与地点状语从句的主要区别：定语从句有表示地点的先行词，而地点状语从句则没有；定语从句修饰的是先行词，地点状语从句修饰的是谓语动词。2.I will always remember the days _ I lived with my grandparents in the countryside.I always remember the days in the countryside _ I see the photo of my grandparents.分析 whenwhen引导定语从句，修

6、饰先行词“the days”，且在从句中作状语。whenwhen引导时间状语从句，修饰谓语动词remember。点拨定语从句与时间状语从句的主要区别：定语从句有表示时间的先行词，而时间状语从句则没有；定语从句修饰的是先行词，时间状语从句修饰的是谓语动词。3.This is such an interesting work of art _ all of us like.This is such an interesting work of art _ all of us like it.分析 assuch.as引导定语从句，as在定语从句中作like的宾语。thatsuch.that引导结果状

7、语从句。点拨定语从句与结果状语从句的主要区别：the same.as与such.as引导定语从句， as在从句中充当一定的成分；such/so.that.引导结果状语从句，that在从句中不作成分。易混点(三)定语从句和名词性从句1. _ is known to everybody, the moon travels round the earth once every month. _ is known to everybody that the moon travels round the earth once every month._ is known to everybody is

8、that the moon travels round the earth once every month.分析 Asas引导非限制性定语从句，修饰后面这句话的内容。Itit作形式主语，真正的主语是that引导的从句。Whatwhat在此引导主语从句，在从句中充当主语，而后面that引导的从句则是表语从句。1.Anyone _has helped to save the drowning girl is worth praising._ has helped to save the drowning girl is worth praising.分析 whowho在此引导定语从句并在从句中作

9、主语。Whoeverwhoever在此引导主语从句。点拨定语从句与主语从句的区别：定语从句是形容词性从句，其作用相当于一个形容词，在整个句子中作定语，用来修饰前面的名词或代词；而主语从句的作用相当于一个名词，在整个句子中作主语。1. The mother made a promise _ pleased all her children.The mother made a promise _ she would buy new toys.分析 that/whichthat/which引导定语从句并在从句中作主语。thatthat引导同位语从句。点拨定语从句与同位语从句的区别：定语从句是形容词性

10、从句，其作用相当于一个形容词，用来修饰前面的名词或代词；同位语从句是名词性从句，其作用相当于一个名词，对前面的名词做进一步解释，同位语从句一般都与抽象名词同位。定语从句的引导词that在从句中充当一定的成分，可作主语、宾语、表语等，作宾语时可以省略；而同位语从句的引导词that在从句中只起连接作用，不作任何句子成分，且不能省略。4.My uncle is the owner of a restaurant close to the place _ is the center of the town.My uncle is the owner of a restaurant close to _

11、 I live.分析 that/whichthat/which引导定语从句并在从句中作主语。wherewhere引导宾语从句。5.Our teacher did all _ he could to help us. Our teacher did _ he could to help us.分析 thatthat引导定语从句并在从句中作宾语。whatwhat引导宾语从句。6. I will help those _ are in need of help. I will help _ is in need of help.分析 whowho引导定语从句，并在从句中作主语。whoeverwhoe

12、ver引导宾语从句。点拨定语从句与宾语从句的区别：定语从句一般有先行词，从句是用来说明、描述先行词的，先行词用关系代词代替，在从句中充当成分(注意是在从句中作成分，如作宾语、主语等)；而宾语从句则是整个从句在主句中作宾语，宾语从句就是主句的宾语，简单地说，动词、介词后面的从句基本上是宾语从句。7.She was not _ she used to be. She was not the woman _ she used to be. 分析 whatwhat引导表语从句。thatthat引导定语从句并在从句中作表语。点拨定语从句与表语从句的区别：表语从句是系动词后的句子；而定语从句是跟在一个名词

13、或句子后，对名词或句子起修饰或补充说明作用的句子。易混点(四)定语从句和固定句型1It was the time _ chinese people had a hard life.2It is the first time_ she has been in Shanghai.分析1.whenwhen引导定语从句，并在从句中作状语。2.thatIt is the first/second/third.time.是固定句型。易混点(五)状语从句和并列句1_ you take this medicine, you will be all right.2Take this medicine, _ yo

14、u will be all right.分析1.Ifif引导条件状语从句。 2andand连接两个并列句。易混点(六)状语从句和名词性从句1Ill try my best to help him, no matter _ turns to me for help.2I will try my best to help _ turns to me for help.3_ turns to me for help is welcome.分析 1.whono matter who引导让步状语从句。2.whoeverwhoever引导宾语从句。3.WhoeverWhoever引导主语从句，并在从句中作

15、主语。易混点(七)状语从句和独立主格结构1_ time permits, well go camping.2Time_ (permit), well go camping.分析1.Ifif引导条件状语从句。2.permitting本句使用的是独立主格结构，其结构为“名词分词”。考点突破针对提能明考点，攻重难，有效提升考点一、时间状语从句1when, while和as引导的时间状语从句when从句谓语动词为延续性动词或非延续性动词。从句的动作和主句的动作可以同时发生，也可以先后发生while从句的谓语动词为延续性动词。从句的动作与主句的动作同时发生as从句谓语动词一般为延续性动词。从句的动作与主
