2020年学位英语备考， 下面小编整理了定语从句分享给大家，定语从句：定语可以由形容词、名词、代词、分词、不定式以及介词短语等来担任，也可以由一个句子来充当，充当定语功能的句子称为定语从句。
1知识点精讲
定语从句的“三要素” 先行词： 被定语从句所修饰的名词或代词 ①指人的先行词 ②指物的先行词 先行词还可以是前面整个句子所叙述的事情。 He has passed the driving test, whichsurprises all of us. (which替代前面所叙述的事情) 先行词2.关系词： 引导定语的词 (1)关系词的作用 ①替代前面的先行词（替代作用） ②连接主句和定语从句（连接作用） ③在定语从句中作句子成分（成分作用） (2)关系词的分类 ①标准：根据关系词在从句中做的句子成分种类 ②关系代词：在从句中做 主，宾，表，定（that/which/who/whom/whose/as） ③关系副词：在从句中作状语(When/where/why)
2.定语从句： 用来做定语，修饰限定先行词的句子 定语从句的分类
性定语从句： 对先行词起限定修饰作用。 He is a teacher whoworks at our school.
非性定语从句： 对先行词起补充说明作用(先行词与定语从句之间有逗号隔开) Beijing, whichis the capital of China, is a beautiful city with a long history. 比较： He has two sons, who work in the same company. (He has only two sons.) He has two sons who work in the same company. (Perhaps he has two more sons)
考点重难点
1.关系代词的省略(限定性定语从句)
(1)关系代词在定语从句中作宾语 She is the girl (whom / that)I loved before. (可以省略whom/that)(2)关系代词在定语从句中作表语 He is no longer the boy (that)he used to be. (可以省略that)(3)关系代词作介词宾语，介词在从句句尾时可以省略 Housing price is a problem(that/which) people are interested in. 比较： Housing price is a problemin whichpeople are interested.（此时只能用which且不能省略）
2.先行词是人(that/who的区别) (1)用that的情况 ①以疑问词who开头的句子中 Who is the man thatis shouting there? ②关系代词在从句中作表语时 She is not the girl thatshe used to be. ③先行词被the very, the right, the only修饰 This is the very person thatwe are looking for.(2)用who的情况 ①先行词是one, ones, anybody, all, none, those 等 Those whowant to go to the cinemawill have towait at the gate of the school. ②句子中有两个定语从句,一个用了that,另外一个用who Who is the boy thatwon the gold medal? ③在there be 结构中 There are many young men whoare against him. ④在非限定性定语从句当中 Tom, whois my best friend,has gone abroad to study.
3.先行词是物(that / which的区别) (1)用which的情况 ①在非限定性定语从句中 She lost the game, whichdepressed her greatly. ②关系词置于介词之后，作宾语 The pen with whichyou writeis Jack’s. ③先行词是that或定语从句中套定语从句,一个关系词用that,另一个用which. Let me show you the novel thatI borrowed from the library whichis newly open to us.(2)用that的情况 ①先行词是不定代词如all, little, few, much,anything, everything, nothing, none, no one等 She did all thatshe couldto help us. ②先行词被all, every, no, some, little, much, the only, he very, the right，the last等所修饰时 This is the very book thatI want. ③先行词中既有人又有物时 She described in her compositions the people andhe places thatimpressed her most.
④先行词前有序数词或形容词高级修饰时 This is the best book thatI have ever read. This is the first film thatI’ve seensince I came here. ⑤定语从句中套定语从句，其中一个关系词以用which, 另外一个用that He built a factory whichproduced things thathad never been seen before. ⑥当主句的主语是疑问词which,另一个用that Who is the person thatis standing at the gate?
4.As引导定语从句用法 (1)As 既可以引导性定语从句也可以用于非限定性定句中充当主语，宾语，表语等。 常用于以下句型当中： Such/so….. as…. 像…..一样 the same …. as… 和…...同样的 A computer is souseful a machine aswe can use everyday. He is not the sameman ashe was.(2)引导非性定语从句，此时译为“正如，像”等。 可以放在句首，句中或句末。 As I remember, there were a net bar here. Taiwan is an inseparable part of China, as is known to all. the same as...和the same that...引导定语从句的区别 This is the samebike thatI lost yesterday.(同一事物) This is the samebike asI lost yesterday. （同类事物）
5.关系副词的运用(1)When 在定语从句中做时间状语，先行词为表示时间的time, day等I still remember the day whenI first came to Beijing. (when=on which)(2)Where 在定语从句中做地点状语，先行词为表地点的place, spot等 Can you tell me the office wherehe works? (where = in which)(3)Why 在定语从句中做原因状语，先行词只有reason. I don’t want to listen to any reason whyyou were absent. (why = for which) 关系副词 = 相应的介词 关系代词 Where引导的定语从句还可以修饰抽象空间的名词如case(情形)，situation, position(位置),stage (阶段)，point（地步）等 What are the situations wherebody languageis the only form of communication? 在哪些情况下身体语言是的沟通方式。(此时where = in which)
6.几个特殊的先行词 (1)way在定语从句中做状语时的三种引导方式 that / in which / 不填 The way in which / that / 不填he explains the sentence to us is quite simple. 比较： The way which /that/不填 he told to us was quite simple. way在定语中作tell的宾语(2)先行词time time表示“次数”时，用关系代词that引导定语从句 This is the first time thatthe president has visited the country. time作“一段时间” 讲时，应用关系副词when This was the time whenthere were no radios, no telephones or no TV sets 此时when = during which 在..期间
(3)先行词reason当在定语从句中作状语时，定语从句的4种引导方式 why/for which/that/不填 This is the reason why/for which/that/不填he can not come here. 比较：Is this the reason that/which/不填he explained to us for his absence from the conference. reason 在定语从句中做explain的宾语
7.介词 关系代词 该结构的关系代词只有两种即 介词 which（指物） 介词 whom（指人） 该结构介词的选用原则：(1)根据定语从句中谓语动词的习惯搭配 This is the book on whichI spent $ 8. This is the book for whichI paid $ 8.(2)根据先行词的搭配习惯 I remember the days during whichI lived there. I remember the day on whichI graduated from university.(3)根据整个句子所表达的意思来决定 The colorless gas without whichwe can’t live is called oxygen.
(4)英语中为了强调某一名词，不定式前面也可以加上关系代词。 Here is the money with whichto buy the piano. She is the right person on whom to depend注意： ①如果介词后移，关系代词可以省略 The person (whom/who/that) you will write to is Todd. ②有些含有介词的动词短语介词不能提前如look for/after; take care of; send for; hear from/of/about deal with等 This is the baby that you will look after.

8.定语从句的主谓一致 (1)当先行词是 one of 复数名词，定语从句的位于动词要用复数形式 The Great Wall is one of the world-famous buildings thatdraw lots of visitorevery year.(2)当先行词是 the only one of 复数名词，从句谓语用单数形式 The Great Wall is the only one of the buildings on the earth thatis seen from themoon.(3)先行词如果是整个句子，定语从句的谓语动词用单数 Great changes have taken place in China, asis known to all. He has passed the driving test, whichsurprises all of us.
9.定语从句的转化 定语从句可以转换为 –ing或-ed形式 The girl(who is) dancing nowjust returned from Taiwan. I love the stories(which were) written by Hemingway. The man(who stands) standing thereis my friend.
10.定语从句的解题方法 (1)判断从句是否为定语从句 （先行词，关系词，定语从句）(2)准确判断先行词在定语从句中的成分(主、宾、表、定、状)从而正确选定使用关系代词或关系副词注意： ①关系代词whose的用法。Whose在定语从句中做定语。 当先行词是人：whose = the 名词 of whom 当先行词是物：whose = the 名词 of which Do you know the boy whose parents / the parents of whom are on holiday? I’d like a room whose window / the window of which faces the sea. ②That引导定语从句，名词性从句 和 强调句型的区别: 定语从句中的that: 关系代词，在后面的定语从句中做句子成分。 名词性从句中的that：从属连词，只起连接主从句的作用，在从句中不做句子成分。
强调句中的that, 运用于it is/was…that..结构；判断标准：去掉强调句型结构，成分仍然完整。比较： This is the book that I am looking for. (that 引导定语从句) It is at Bashu middle school that I have studied for three years. (that和前面的it is构成强调句型) The fact that he stole the moneysurprised all of us. (that 引导名词性从句--同位语从句) That he will come to the conferencehas excited all of us. (that引导名词性从句--主语从句) We all expect that they win, for members of their team are stronger. (that引导名词性从句--宾语从句) The reason for your failure isthat you lack confidence in yourself. (that 引导名词性从句--表语从句

【参考答案】
1. A. 主语与run(延伸)是主动关系，所以用现在分词。 Those指街道，所以不用who而用that来引导定语从句。
2. B. 因为在此题中where引导定语从句，表示“在这种种况下”，与in which相当。
3. A. 因为先行词是Beijing而不是this autumn所以用where引导定语从句。
4. B. 答案B是省略了关系代词that的定语从句，另外，to后还省略了动词原形paint。
5. C. 因为of which引导定语从句，并在从句中作定语。 of which the telephone number = whose telephone number。
6. D. 因为这是个非性定语从句，先行词是前面一句话的内容。
7. B. 因为表示“阶段、程度、地步”的the point在定语从句中作地点状语，所以用where引导定语从句。
8. B. 因为先行词是research centers并在定语从句中作状语，所以用where。
9. C. 因为当先行词是表示事物的all, little, few, much, anything, everything, nothing等时，多用that引导定语从句。
10. 因为先行词是the time，且在定语从句中作状语，所以用when引导。 此题的先行词与定语从句被主句谓语分开了，要善于辨别。
11. B. 先行词是Taiwan is a part of China整个主句，一般由as或which引导定语从句，但which引导的定语从句只能放在主句之后，另外，as有“正如”之意，而which没有，所以用as。 顺便说说，原句改为： It is known to everybody that Taiwan is…= What is known to everybody is that Taiwan is…
12. A. 两空都是考查定语从句，先行词分别是the day和Shen Zhou V was launched, the day在定语从句中作状语，用when引导； 后句是非性定语从句，不能用that，要用which。
13. A. 因为替代不可数名词 (the bread) 只能用that，排除B和D； 又因为先行词that (the bread) 在定语从句中作buy的宾语，用which，所以选A。

14. D. 当定语从句的先行词前有such, so, as等词语时，由as引导，并且as在定语从句中作主语或宾语，as在此题中作dream of的宾语。 注意： 在表示“如此…以致…”的such /so…that…结构中，that不作任何句子成份。
15. B. 考查非性定语从句，all of whose homes = all of their homes他们所有的房子。
16. D. 因为先行词是前面整个句子，且在从句中作主语，所以用which。 of course是插入语。
17. D. 将疑问句改为陈述句： this research center is…显然缺少先行词，必须加上代词the one来作先行词，又因定语从句不缺主语或宾语，所以用关系副词where。 假若在this后加the，就选where，请想想这是为什么。
18. A. 因为先行词是the days，并在定语从句中作状语。
19. B. 当先行词前有so时，用as引导定语从句，as在从句中作主语或宾语。 假若在lift后加上it，答案就是that了，请想想这是为什么。
20. C. 因前后均的句子，必须要选连词，排除B和D； 又因在介词后不能用that来引导定语从句，所以选C。 during which time在那段时间里。
