1、高中英语语法复习专题讲解高中英语语法复习专题讲解-定语从句一、考点聚焦1、功能:相当于形容词,修饰名词或代词,在句中作定语2、位置:定语从句置于被修饰词之后Those who are willing to attend the party, sign here please.3、先行词:被定语从句修饰的词称为先行词(1)先行词一般是名词和不定代词,如:some-, any-, every-和no与-boy, -thing的合成词;或all、none、any、some、that、those等代词。数词也可以作先行词,人称代词也同样可作先行词。(2)先行词与关系词是等量关系。必须注意两点:先行词在
2、从句中作主语时,从句谓语动词的数由先行词而定。This is the place which is worth visiting.关系词在从句句子中充当了成分,其意思就是先行词的意义,所以在从句中不能重复其意。There are many places we can visit(them)in China.4、关系词:引导定语从句的都称关系词关系代词:who, whom, which, that, whose, as。关系副词:when, where, why。that偶尔也作关系副词。5、确定关系词的步骤(1)先找关系词,看先行词指的是什么。(2)看关系词在从句中所充当的成分。6、在定语从句
3、中,当先行词指物时,下列情况的关系词宜用that而不用which(1)先行词被形容词最高级 序数词 数词几种词修饰或被 only、any、few、little、no、all、one of等修饰时。(2)先行词为all、much、little、none、few、one、something、anything等不定代词时。(3)先行词中既有人又有物时。He was looking pleasantly at te children and parcels that filled his bus.(4)先行词在主句中作表语关系词在从句中作表语时。The village is no longer the
4、 one that was 5 years ago.(5)当主句中含有疑问词which时。Which are the books that you bought for me ?7、宜用which而不用that的情况(1)在非限制性定语从句中(2)在关系词前有介词时(3)当先行词本身是that时(4)当关系词离先行词较远时8、关系词who与that指人时,也有不同情况分别用不同的关系词(1)当主句是there be句型时,关系词用who。(2)先行词是为anyone、those、someone、everyone、one等词时,关系词用who。(3)当主句是who作疑问词时,关系词用that。W
5、ho is that girl that is standing by the window?(4)whom在从句中只作宾语,可被who取代。9、whose作关系词既指人又指物,在从句中作定语。如:Do you know Mr.Smith whose story is very moving ?There is a room, whose window faces the river.There is a room, the window of which faces the river.10、关系代词as,在从句中作主语、宾语和表语。(1)先行词被such和the same修饰,或句型as
6、many(much)中,从句都用as 引导。Such books as you bought are useful.The school is just the same as it was 10 years age.注意:区别such that 引导的结果状语从句。They are suchlovely children that we love them much.the same that 引导定语从句。I want to use the same tool that you used just now.(2)无先行词的定语从句用as和which引导。区别:意义上:as 含有“这点正如一
7、样”。位置上:as 从句可置句首,也可在另处。He didnt pass the exam, as we had expected.There is lots of air in loose snow, which can keep the cold out.As is known, the earth is round, not flat.11、关系副词when与where、why、thatwhen 指时间 = in / at / on / during whichwhere指地点 = in / at / from / whichwhy指原因 = for which当先行词为way、day、
8、reason、time时,可用that作关系副词。(非正式场合)I dont like the way that / in which / he talks.当time作先行词时,关系词可以省掉。This is the first time I have given you a lesson in French.12、必须注意的问题(1)关系词作主语时,从句中谓语的数。(2)注意区别定语从句与强调句。定语从句中关系词作从句成分,复合句。强调it无意义,that / who不是引导词。强调it is / was和that / who后如果句子意思讲得通则是强调句,讲不通则不是。It is the
9、 museum that / which we visited last year.(定语从句)It was in the hotel that we stayed last night.(强调句)(3)定语从句与同位语从句的区别。定语从句引导词被称为关系词,that充当主语、宾语、表语。有时可省略。同位语从句引导词被叫做连词,that不能充当任何成分,不可省。Word came that their army was defeated.(同位语)We expressed to them our wish that was the same as their.(定语)(4)关系词在从句中省略的
10、情况。关系词作宾语,前无介词时。关系词作表语。(5)限制性定语从句与非限制性定语从句的翻译。(6)关系词前有介词或复杂介词,关系词只能是which和whom。(7)几个特殊的定语从句句型:He is the only one of the students who has got very good marksin the match.(句中one为先行词)He is one of the students who have got good marks in the match.(句中students为先行词)Is this place the one (that) we visited y
11、esterday?Is this the place(that / which)we visited yesterday ?He stood at the window, from where he could see what was happening.It may rain, in which case the match will be put off.二、精典名题导解选择填空1.

12、 C.when D.where2. _ is known to everybody, the noon travels around the earth once every month.A.It B.As C.That D.What3. After living in Pairs for fifty years he returned to the small town _ he grew up as a child.A.which B.where C.that D.when (后附解析)词(关系代词或关系副词)引出。 关系代词有:who, whom, whose, that, which等
13、。 关系副词有:when, where, why等。 18.1 关系代词引导的定语从句 关系代词所代替的先行词是人或物的名词或代词,并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时,从句谓语动词的人称和数要和先行词保持一致。 1)who, whom, that 这些词代替的先行词是人的名词或代词,在从句中作主语和宾语。例如: Is he the man who/that wants to see you? 他就是你想见的人吗?(who/that在从句中作主语) He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。(whom
14、/that在从句中作宾语) 2) whose 用来指人或物,(只用作定语, 若指物,它还可以同of which互换)。例如: They rushed over to help the man whose car had broken down.那人车坏了,大家都跑过去帮忙。 Please pass me the book whose (of which) cover is green.请递给我那本绿皮的书。 3)which, that所代替的先行词是事物的名词或代词,在从句中可作主语、宾语等。例如: A prosperity which / that had never been seen b
15、efore appears in the countryside. 农村出现了前所未有的繁荣。(which / that在句中作宾语) The package (which / that)you are carrying is about to come unwrapped. 你拿的包快散了。(which / that在句中作宾语) 18.2 关系副词引导的定语从句 关系副词可代替的先行词是时间、地点或理由的名词,在从句中作状语。 1)关系副词when, where, why的含义相当于介词+ which结构,因此常常和介词+ which结构交替使用。例如: There are occasio
16、ns when (on which) one must yield.任何人都有不得不屈服的时候。 Beijing is the place where(in which) I was born.北京是我的出生地。 Is this the reason why (for which) he refused our offer?这就是他拒绝我们帮助他的理由吗? 2)that代替关系副词,可以用于表示时间、地点、方式、理由的名词后取代when, where, why和介+which引导的定语从句,在口语中that常被省略。例如: His father died the year (that / wh
17、en / in which) he was born.他父亲在他出生那年逝世了。 He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住过的地方。 18.3 判断关系代词与关系副词 方法一: 用关系代词,还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语,就必须要求用关系代词;而不及物动词则要求用关系副词。例如: This is the mountain village where I stayed last year. 这是我去年呆过的山村。
18、 Ill never forget the days when I worked together with you.我永远不会忘记与你共事的日子。 判断改错: (错) This is the mountain village where I visited last year. (错) I will never forget the days when I spent in the countryside. (对) This is the mountain village (which) I visited last year. (对) Ill never forget the days (
19、which) I spent in the countryside. 习惯上总把表地点或时间的名词与关系副词 where, when联系在一起。此两题错在关系词的误用上。 方法二: 准确判断先行词在定语从句中的成分(主、谓、宾、定、状),也能正确选择出关系代词/关系副词。 例1. Is this museum _ you visited a few days age? A. whereB. that C. on which D. the one 例2. Is this the museum _ the exhibition was held. A. whereB. that C. on whi
20、chD. the one 答案:例1 D,例2 A 例1变为肯定句: This museum is _ you visited a few days ago. 例2变为肯定句: This is the museum _ the exhibition was held. 在句1中,所缺部分为宾语,而where, that, on which都不能起到宾语的作用,只有the one既做了主句的表语,又可做从句的宾语,可以省略关系代词,所以应选D。 而句2中, 主、谓、宾俱全,从句部分为句子的状语表地点,既可用副词where,又因 in the museum词组,可用介词in + which 引导地
21、点状语。而此题中,介词on 用的不对,所以选A。 关系词的选择依据在从句中所做的成分,先行词在从句中做主、定、宾语时,选择关系代词(who, whom, that, which, whose); 先行词在从句中做状语时,应选择关系副词 ( where 地点状语,when 时间状语,why 原因状语) 。 18.4 限制性和非限制性定语从句 1) 定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分,去掉它主句意思往往不明确;非限制性定语从句是先行词的附加说明,去掉了也不会影响主句的意思,它与主句之间通常用逗号分开。例如: This is the house which we b
22、ought last month. 这是我们上个月买的那幢房子。(限制性) The house, which we bought last month, is very nice. 这幢房子很漂亮,是我们上个月买的。(非限制性) 2) 当先行词是专有名词或物主代词和指示代词所修饰时,其后的定语从句通常是非限制性的。例如: Charles Smith, who was my former teacher, retired last year. 查理?史密斯去年退休了,他曾经是我的老师。 My house, which I bought last year, has got a lovely ga
23、rden. 我去年买的的那幢房子带着个漂亮的花园。 This novel, which I have read three times, is very touching. 这本小说很动人,我已经读了三遍。 3) 非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数。例如: He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思,这使我心烦。 Liquid water changes to vapor, which is called evaporati
24、on. 液态水变为蒸汽,这就叫做蒸发。 说明:关系代词that和关系副词why不能引导非限制性定语从句。 18.5 介词+关系词 1)介词后面的关系词不能省略。 2)that前不能有介词。 3)某些在从句中充当时间,地点或原因状语的介词+关系词结构可以同关系副词when 和where 互换。例如: This is the house in which I lived two years ago. 这是我两年前住过的房子。 This is the house where I lived two years ago. Do you remember the day on which you joi
25、ned our club? 还记得你加入我们俱乐部的那一天吗? Do you remember the day when you joined our club? 18.6 as, which 非限定性定语从句 由as, which 引导的非限定性定语从句,as和which可代整个主句,相当于and this或and that。As一般放在句首,which在句中。例如: As we know, smoking is harmful to ones health. 如我们所知,吸烟有害健康。 The sun heats the earth, which is very important to
26、us. 太阳使地球暖起来,这对我们人类很重要。 典型例题 1)Alice received an invitation from her boss, _came as a surprise. A. it B. that C. whichD. he 答案C. 此为非限定性从句,不能用 that修饰,而用which.,it 和he 都使后句成为句子,两个独立的句子不能单以逗号连接。况且选he句意不通。 2)The weather turned out to be very good, _ was more than we could expect. A. whatB. whichC. thatD.
27、 it 答案B。which可代替句子,用于非限定性定语从句,而what不可。That 不能用于非限定性定语从句,it不为连词,使由逗号连接的两个句子并在一起在英语语法上行不通。 3)It rained hard yesterday, _ prevented me from going to the park. A. thatB. whichC. as D. it 答案B. as 和which在引导非限制性定语从句时,这两个关系代词都指主句所表达的整个意思,且在定语从句中都可以作主语和宾语。但不同之处主要有两点: (1)as 引导的定语从句可置于句首,而which不可。 (2) as 代表前面的
28、整个主句并在从句中作主语时,从句中的谓语必须是系动词;若为行为动词,则从句中的关系代词只能用which.。在本题中,prevent由于是行为动词,所以正确选项应为B。 as 的用法 例1. the sameas;suchas 中的as 是一种固定结构, 和一样。例如: I have got into the same trouble as he (has). 我碰到了跟他一样的麻烦。 例2. as可引导非限制性从句,常带有正如。例如: As we know, smoking is harmful to ones health. 如我们所知,吸烟有害健康。 As is known, smokin
29、g is harmful to ones health. As是关系代词。例1中的as作know的宾语;例2中,它充当从句的主语,谓语动词know要用被动式。 18.7 先行词和关系词二合一 1) Whoever spits in public will be punished here. (Whoever 可以用 anyone who 代替) 2) The parents will use what they have to send their son to technical school.(what 可以用all that代替) 18.8 what/whatever; that/wha
30、t; who/whoever 1)what = the thing which;whatever = anything。例如: What you want has been sent here. 你要的动词都送来了。 Whatever you want makes no difference to me. 不管你要什么,跟我没什么关系。 2) who= the person that whoever= anyone who。例如: (错)Who breaks the law will be punished. (错)Whoever robbed the bank is not clear. (对)Whoever breaks the law will be punished. 王子犯法,与庶民同罪。 (对)W
