2、 关系词：引导定语从句的词叫关系词。关系代词：who/whom (指代人), which（指代物），that（指代人/物），as, whose等关系词的分类:关系副词：when （指代时间），where (指代地点)，why (指代原因)1. 引导定语从句关系词的功能: 2. 代替先行词在定语从句中担当一个句法成分解题步骤总结：1、找出先行词，划出定语从句2、判断选择关系代词还是关系副词,（缺主、宾、表语用关系代词，不缺成分用关系副词）3、根据语境选择合适的关系词三、基础知识学习：I. 关系代词that, which, who(whom)引导的定语从句1.指人的关系代词: who / whom

3、 / that先行词在从句中作主语 ：A doctor is a person who / that looks after peoples health.先行词在从句中作宾语 ：Mr White invited many friends to his party (who / whom / that) he respected much.关系代词前有介词：Nancy is the right person on whom you can depend.2.指物的关系代词: which / that先行词在从句中作主语：The river which / that runs through t

4、he city brings us lots of pleasure.先行词在从句中作宾语：The book (which / that) you just laid on the shelf is mine.关系代词前有介词： Here is the money with which I will buy a piano.总结：关系代词中在从句中充当主语的是which、that、who且在句中不可以省略。关系代词中在从句中充当宾语的是which、that、who、whom且可以省略。当关系代词前有介词时，指人只能用 whom， 指物只能用which。which 只能指物，whowhom 只能

5、指人，that既可指人又可指物。3.表示所有格：whose (既表示人的所有也表示物的所有)表示人的所有： The girl whose father is a model worker is our monitor.表示物的所有： Id like a room whose window looks out over the sea.the + 名词+of + whom (which) 的结构= whose + 名词，下面三句意思相同，例如：The river whose banks are covered with trees flows to the sea.The river of wh

6、ich the banks are covered with trees flows to the sea.The river the banks of which are covered with trees flows to the sea.There are twenty students, whose backgrounds are different.There are twenty students, the backgrounds of whom are different.There are twenty students, of whom the backgrounds ar

7、e different.活学活用：The classroom whose door is broken will be repaired soon._记住下列表格:关系代词指人指物主格who、that、that、which、宾格whom 、who、that、that、which、所有格of whom 、whoseof which、whose、 注意：关系代词只能用that，而不能用which的情况：1) 当先行词为不定代词（something,anything,all, little,much等）。如：There is nothing (that) I can say about it.I a

8、m interested in all that you have told me.There isnt much that I can do.2）序数词或形容词最高级修饰先行词时。如：This is the best basketball match that I have ever seen.The first English film that I saw was “Oliver Twist”.3）先行词被the only，the very或the last修饰时。如：The only thing that we can do is to ask our teachers help.Is

9、 this the very museum that you visited the other day?4）先行词既指人又指物时。例如：They talked about the factories and workers that they had visited.先行词被all, any, every, few, much,little, no，some等修饰时 I have read all the books that you gave me. Any boy that wants to succeed must work hard.6）当句中已有which或who时，为避免重复，多

10、用thatWhich is the book that he bought yesterday?Who that you have ever seen can beat him in the game?练习：Egypt is a country _is famous for its pyramids.On the train I saw a student _was sleeping.This is the book _she gave me yesterday.She is my mother _the teacher is talking with now.Is there anythin

11、g _ I can do for you?This is the best hotel _I know.Dont stay in the room _roof is under repair.I know the boy _ambition is to become a soldier.The composer _ _ the teenagers are familiar has written many songs.Mary lives in a large room, the door of _opens east.2. 关系副词where when why引导的定语从句Do you re

12、member the teahouse where we used to play chess? (where=at which)There was a time when there was no radio, TV or cinema. (when=during which)The days are gone when he was an ignorant boy. (when=in which)They didnt explain the reason why they had canceled the rehearsal. (why=for which)（定语从句中关系副词 = 介词

13、+ 关系代词）注意：有些先行词后面既可以用关系代词，也可以用关系副词。判断的重点在于分析先行词在定语从句中充当什么句子成分。 以the city 为例(1) This is the city that/which I visited last year.分析：主句：This is the city. 从句：I visited the city last year. visit：vt.，the city充当的成分：宾语(2) This is the city where I lived last year.分析：主句：This is the city. 从句：I lived in the cit

14、y last year. live：vi.，the city 充当的成分：状语，表地点。练习：He took us to a small town _he intended to settle down.This is the small village _I often visited when I was a child.I will never forget the days _we spent together last year.I will never forget the days _we stayed together last year.This is the small h

15、otel _we stayed not long ago.It is a factory _his father worked a few years ago.Can you tell the reason _the car broke down?The reason _he failed in the test is that he didnt study hard.Nobody believes the reason _the worker explained for his carelessness in his work.Do you know the reason _ _he was

16、 late?四、其他情况：限制性定语从句与非限制性定语从句限制性定语从句对先行词起限制作用，是先行词不可缺少的定语，如果去掉句子的意思不完整，不明确或失去意义。这种从句与主句的关系十分密切，写时不用逗号隔开。 I have found the key that I lost yesterday. It happened at the time when I left.非限制性定语从句和先行词的关系比较松散，只是对先行词作附加说明的作用。如果去掉，主句的意思仍然清楚，这种从句与主句之间常用逗号隔开。 He lives in Beijing, which is about five hours r

17、ide from here. My cousin, who is an engineer, went to Europe last week. His speech, which bored everyone, went on and on.She is working hard，which everyone can see.两者区别区别限制性定语从句非限制性定语从句形式与主句之间不用逗号隔开与主句之间一般用逗号隔开功能对先行词进行限定、修饰。如果去掉，剩余部分的意义便不完整、不明确对先行词作附加说明，去掉后，句子剩余部分的意思仍然完整、明确先行词名词或名词性词组名词、名词性词组或整个主句引导

18、词所有的关系代词/副词除that和why之外的关系代词/副词翻译常译成前置定语常译成并列分句【提示】并非只有which才能引导非限制性定语从句。使用非限制性定语从句时，如果先行词指人，可用who，whom或whose来引导；先行词指物，可用which，whose来引导；先行词表时间或地点，可用when，where来引导(它们在从句中分别作时间状语和地点状语)。总结：非限制性定语从句不能用that引导非限制性定语从句不能用why引导，要用for which代替whyI had told them the reason, for which I didnt attend the meeting.I

19、 had told them the reason why(for which) I didnt attend the meeting.在非限制性定语从句中，指人的关系代词作宾语时只能用whom,不能用who,也不能省略 Do you know Tom, whom we talked about?练习：Chapin, _has earned enough money, will start a new life.The chairman, _spoke first, sat on my right.He must be from Africa, _can be seen from his sk

20、in.His sister has become a doctor, _made their parents very proud.Amy, _father was a doctor, gave me a kind smile.He will put off the picnic until May, _he will be free.No outdoor sports will be allowed tomorrow,_the weather will be terrible.He used to live in Canada, _English is used to as the offi

21、cial language.二、as在定语从句中的用法1as引导非限制性定语从句（和which的区别）a. as引导非限制性定语从句时，先行词一般为整个主句；而which引导非限制性定语从句时，先行词既可以是整个主句又可以是主句的一部分。bas引导的从句位置比较灵活，可位于先行词之前、之中和之后，而which引导的从句仅能位于先行词之后。As is known to all, the earth goes around the sun.As was expected beforehand, the concert was very successful.Bamboo is hollow, wh

22、ich makes it very high.cas引导从句时常译为“正如”，而which常译为“这；那”。常用句型有：as we all know，as is known to all，as everybody can see，as is expected等。He did the experiment successfully，as had been expected.正如期望的那样，他试验做得非常成功。He failed in the experiment，which was unexpected.他试验失败了，这是没有料到的。2.as作关系代词的用法(用于固定结构中）常作主语或宾语as引导的定语从句常出现于the sameas,suchas,asas和soas结构中,解释为和.一样。当定语从句的先行词被the same，such，as 或so修饰时，关系代词可选as，且不能省略。Lets meet at the same place as we did yesterday.让我们在和昨天碰面的同样的地方碰头吧。I never heard such stories as he told. 我从未
