1、高中英语定语从句语法复习(名师精讲必考知识点，值得下载练习)一几个基本概念1.定语从句的定义：用作定语的从句叫定语从句。2.先行词：被定语从句所修饰的名词或代词。3.定语从句的位置：紧跟先行词（名词或代词）之后。4.引导词：引导定语从句的词（包括关系代词和关系副词）。1关系代词：that/who/whom/which/as 2关系副词：when/where/why 5.引导词的位置：位于定语从句之前（先行词之后）。【as 除外】6.引导词的功能（作用）：1连接先行词和定语从句。2在定语从句中充当一定的成分（关系代词充当主语或宾语，关系副词充当状语）。7.定语从句的类型：1限定性定语从句（主句和
2、定语从句之间无逗号）。直接由引导词引导定语从句The man who youre talking to is my friend.由介词+关系代词（whom/which）引导The man to whom youre talking is my friend.I need a pen with which I can write a letter.=I need a piece of paper on which I can write a letter.介词的选用可根据从句中的相关词组确定，该介词通常可以放在关系代词之前，也可放在从句之尾。例如：The man(who/whom/that)I
3、 talked about at the meeting is from Beijing University.=The man about whom I talked at the meeting is from Beijing University.The palace(which/that)I often pay a visit to was built in the 17th century.=The palace to which I often pay a visit was built in the 17th century.2非限定性定语从句（主句和定语从句之间用逗号隔开）。直
4、接由引导词引导定语从句。由介词+关系代词（whom/which）引导。I live in a house far away from the city,in front of which is a big tree.There is an apple tree standing at the gate,on which are many apples.This is the man to whom I gave the book.由“代词/名词+of+whom/which”或“of which/whom+名词/代词”（先行词指人用 whom,指物用which)引导。One,some,any,n
5、one,all,both,several,many,most,neither,either等词、数词、分数或百分比与of whom 或 of which连用。He has five children,two of whom are abroad.(比较：He has five children,and two of them are abroad.)We have three books,none of which is/are interesting.(比较：We have three books,but none of them is/are interesting.)除 why 和 th
6、at 不能引导非限定性定语从句 外，其余引导词都可以，用法同限定性定语从句一样。但要注意以下区别。1.在形式上非限定性定语从句与主句有逗号隔开。2.非限定性定语从句的作用：它只是补充说明先行词的情况，翻译时可译成两个句子。The engineer,whose leg was badly hurt,was quickly sent to hospital.（那位工程师被很快送往医院，其腿部受了重伤）The engineer whose leg was badly hurt was quickly sent to hospital.（那位腿部受了重伤的工程师被很快送往医院）3.在非限定性定语从句中
7、，任何引导词都不能省略（包括引导词在此定语从句中充当宾语在内）。指人做主语时只能用who,做宾语时用 whom;指物做主语，宾语都用which;关系副词用 when 或 where，也不能省略。The man,_ is sitting on the chair,is my father.The woman,_ I met yesterday,is my English teacher.The city,_ is far away,is very beautiful.He went to America,_ his parents live.He joined the Army yesterda
8、y,_ I left,too.4.whose 引导非限定性定语从句：The house,whose window faces south,is mine.=The house,the window of which faces south,is mine.The house,of which the window faces south,is mine.二.定语从句中关系代词和关系副词的基本用法。1.who/that指人是主格在定语从句中代替先行词，又作定语从句的主语，不能省略。Do you know the gentleman who/that is sitting there?2.whom
9、/who/that指人是宾格，在定语从句中代替先行词，又作定语从句的宾语（动宾或介宾）。当作动宾（动词后接宾语）时，关系代词可省略。Do you know the gentleman(whom/who/that)we met just now?当作介宾（介词后接宾语）时：介词不提前时，关系代词可省略；介词提前时，关系代词不可省，即介词whom(指人时介词后的关系代词只能用whom)。The man(whom/who/that)I spoke with is my teacher.The man with whom I spoke is my teacher.注：固定的动词短语（动词+介词）如
10、look for,take care of等不能把动词与介词拆开，既介词不能提至引导词前。She is the right girl(who/whom/that)we are looking for.3.whose:指人或物，是所有格“的”形式。Whose+n.一起在定语从句中充当主语、宾语（动宾或介宾）即先行词的什么东西怎样了，whose 不能省略。Whose+n.=the+n.+of which/whom=of which/whom+the=n.I didn t find the desk whose leg was broken.（主语）He is the student whose p
11、encil I broke yesterday.（动宾）The boss in whose company I work is very kind.（介宾）4.which/that 指物，指代先行词且在定语从句中作主语或宾语（动宾或介宾）。当作动宾时，关系代词可省略。当作介宾时：介词不提前时，关系代词可省略；介词提前时，关系代词不可省，即介词 which(指物时介词后的关系代词只能用which)。The house which/that was destroyed in the earthquake is weak.The pen(which/that)you found yesterday
12、is mine.The games(that/which)the young men competed in were difficult.The games in which the young men competed were difficult.注:介词+关系代词即介词+whom/which(先行词指人用whom，指物用 which)。5.as指人或物，在定语从句中可作主语，宾语，表语或状语，不能省略。主要用于“the same as；such as；so as；as as；as follows”固定结构中，形式固定此时的引导限定性定语从句。要用 as 代替 who(m),which,
13、或 that引导定语从句：Such people as knew Hill thought he was honest.Such people as Hill knew thought he was honest.My hometown is no longer the same as it was.Here is so big a stone as no one can lift.The child knows as much as grow-ups(know).I d like to have the same books as a re used in your school.He is
14、 not such a person as I expected.He will marry as pretty a girl as he can find.注：which 和 as 可引导非限定性定语从句：可以指代主句中的一部分或整个句子的内容，which 和 as 都可以指代主句中的一部分或整个句子的内容，有时可以互换。因此，当 as/which 指代前面的整个句子，或前句中的部分内容作定语从句的主语时，谓语用单数Our team lost the game,as/which was reported in the newspaper.She was terrified,as/which
15、I could see from her eyes.He married her,as/which was natural.区别：as 引导的非限制性定语从句可以放在主句前面、插在主句中间或放在主句末尾；而 which 引导的非限制性定语从句只能放在主句后面。He married her,as/which was natural.=As was natural,he married her.Mark Twin is a great writer,which/as is known to all.=As is known to all,Mark Twin is a great writer.as
16、 引导的从句有“正如”、“正像”之意，而 which 则无此意。常用句型有：as we all know,as is known to all,as everybody can see,as is expected,As is known/said/reported/told/we all know等。如：As we all know,paper was first made in China.To shut your eyes to facts,as many of you do,is foolish.主句和从句有因果关系时，用which.Our class has won the foot
17、ball match,which made us very happy.Bamboos are hollow,which makes them very light.从句含否定意义时常用which.She didnt pass the exam,which we couldnt expect.She didnt pass the exam,as we expected.6.when 关系副词：指时间。在定语从句中作时间状语，不能省略。此时的when还可用介词+which 替换（此时先行词一定是表时间的名词）。I still remember the time when I joined the
18、 League.I still remember the time on which I joined the League.I still remember the time(which/that)I joined the League on.7.where 关系副词：指地点。在定语从句中作地点状语，不能省略。此时的when还可用介词+which 替换（此时先行词一定是表地点的名词）。I still remember the school where I joined the League.I still remember the school in which I joined the L
19、eague.I still remember the school(which/that)I joined the League in.注：对关系副词 when,where 的认识。.先行词是时间的名词，并非都用关系副词when 引导定语从句。I ll never forget the time(which/that)I spent in Beijing.先行词是地点的名词，并非都用关系副词where 引导定语从句。This is the factory(which/that)he visited yesterday.当句型为 It/This/That is(was)the first(sec
20、ondlast)time 引起的句子时用that连接其后的句子。此时的time 是次数，不是时间。It/This is the first time that we travel.It/This is the last time that I shall give you a lesson.8.why 指原因，在定语从句中作原因状语，先行词通常为reason,不能省略。且why 引导的定语从句只能是限定性定语从句。Why=for which I don t know the reason why he was late yesterday.The reason why(for which)he
21、 was late is that he missed the bus.注：当先行词为 reason 时，关系副词并非都用why。This is the reason(that/which)he gave/explained to us.【判断用关系代词还是关系副词】从句缺少的是主语、宾语还是状语是确定用关系代词还是关系副词的关键。试比较：I will never forget the day(which/that)I spent in Hongkong.(spent 是及物动词，后缺宾语，因此用关系代词或省略)I will never forget the day when/on which
22、 Hongkong returned to its motherland.（从句主谓宾结构完整，缺状语，因此用关系副词或介词加关系代词）The reason（that/which）he gave for not coming to school yesterday isnt believable.(gave 是及物动词，后缺宾语，因此用关系代词或省略)The reason why he didnt come to school yesterday isnt believable.（从句主谓宾结构完整，缺状语，因此用关系副词或介词加关系代词）三.值得注意的几个问题：第一.当先行词是物时，关系代词
23、(that/which)只用 that 的情况。1.当先行词被序数词或形容词的最高级修饰时。This is the best film that has been shown this year.This is the first book(that)I borrow from the library.He is the first student that/who came to school today.2.当先行词为两个或两个以上分别指人和物的名词时。He talked about the teachers and the school(that)he had visited.3.当先行
24、词本身是all 的，用 that。(all that=what)All that(what)I want to say to you is“Thank you”=All(what)I want to say to you is“Thank you”Go over all that(what)we learned.=Go over all(what)we learned.（that 在定语从句中充当宾语可以省略）4.先行词为 something,anything,nothing,everything,thing时，用 that.I ll tell you anything(that)I know
25、.5.当先行词前有 all,much,little,many,(a)few,every,some,any,no,only,the very,one of,the only,the last,the next等修饰语时。This is one of the books(that)Im very interesting in.This is one of the books in which Im very interesting.This is the only book(that)I read.He is the only one of the boys that likes playing
26、the piano.All the glasses that were on the table fell off onto the floor.6.（人，物），当先行词在以who 或 which 开头的特殊疑问句中时，用that 引导以避免混淆Who is the man that is talking with the lady?Which of you that know the answer can come to the front?7.当先行词是在定语从句中作表语时，用thatHe likes the girl that she used to be.第二.当先行词是物时，关系代词
27、(that/which)只用 which 的情况。1.作介宾且介词置于引导词之前时The room in which he lives is very large.2.引导非限定性定语从句时（主，宾都用which,都不能省略）Football,which is a very interesting game,is played all over the world.The house,which I visited yesterday,is very large.3.which 指整个句子的内容或部分内容，引导非限定性定语从句He always makes fun of me,which up
28、sets me.第三.其他特殊情况1.先行词是 these,those指人时，关系代词只用who.Those who are playing over there are my students.2.先行词是人称代词(he,she）时，关系代词只用who.He who doesnt reach the Great Wall is not a true man.3.不定代词 someone,anyone,everyone,no one,somebody,anybody,everybody作先行词时，关系代词用who.Anybody who breaks the rules would be pu
29、nished.4.先行词是 the only one of+可数名词复数，在定语从句中作主语时，定语从句中的谓语用单数形式（因为此时的先行词是 the only one,而不是 of 后的可数名词复数）He is the only one of the boys that likes playing the piano.This is the only one of the books that is borrowed.先行词是 one of+可数名词复数，在定语从句中作主语时，定语从句中的谓语用复数形式（因为此时的先行词是of 后的可数名词复数,而不是 one）This is one of
30、the students who are late.5.当主句缺先行词时，用the one 代替，但须注意：the one 只能代替可数名词单数如为不可数名词时，指什么用什么Is this school the one I visited yesterday?Is pop music the music he likes best?6.当先行词是 the way,在定语从句中充当方式状语时（the way 表以 方式方法），引导词通常用 that 或省略，也可用 in which I don t like the way(that)you speak.=I don t like the way
31、 in which you speak.=I don t like the way(which/that)you speak in.【“介词+关系代词”十种情况】在定语从句中，介词+关系代词结构是一种较为复杂的问题。现就几种常见的介词+关系代词的结构浅析如下：1介词+which在定语从句中分别作时间、地点和原因状语，代替相应的关系副词 when,where 和 why。如：I still remember the day on which(when)I first came to school.我仍然记得初来学校的那一天。The factory in which(=where)I work i
32、s a large one.我工作的工厂是一个大工厂。This is the reason for which(=why)he was late.这就是他为什么迟到的原因。2介词+which（指物）/whom（指人）在定语从句中作地点状语，表示存在关系，定语从句主谓一般要倒置。They arrived at a farmhouse,in front of which sat a small boy.他来到一处农舍，前边坐着一个小男孩。I saw a man,on the head of whom stood a bird.我看见一个人，他的头上站着一只鸟。3介词+which（指物）/whom（
33、指人）在定语从句中作目的、方式或地点状语。这种结构中的介词一般受动词或介词后的名词所制约。如：Could you tell me for whom youve bought this coat?你能告诉我这件衣服是给谁买的吗？The man,from whom I learned the news,is an engineer.这人是一位工程师，我是从他那里得到这消息的。4介词+which/whom，用于被动结构的定语从句中，作状语，说明动作的出发者。如：The wolf by which the sheep was killed was shot.伤害羊的那只狼被打死了。The man by
34、 whom the wolf was shot was a good hunter.打死狼的那人是个好猎手。5不定代词+of+which/whom，在定语从句中作主语，说明整体中的部分，常用的不定代词有：both,all,any,some,each,none,most等。如：There are a lot of books here,none of which belongs to me.这儿有许多书，可一本也不属于我。Yesterday Mary bought a few clothes,all of which were expensive.昨天玛丽买了一些衣服，他们都很贵。6数词+of+
35、which/whom，在定语从句中作主语，说明整体与部分的关系。数词可以是基数词、序数词、分数或百分数。如：In our class there are fifty-four students,twenty-five of whom are girls.我们班有 54名学生，25 人是女生。Two watches were stolen,one of which was mine.两只手表被偷了，其中一只是我的。7名词+of+which代替 whose+名词，在定语从句中作定语。如：I saw some trees,the leaves of which(=whose leaves)were black with disease.我看见一些树，他们的叶子因害病而发黑。
