1、高中英语定语从句讲解及练习 定语从句在句中做定语，修饰一个名词或代词，被修饰的名词词组或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。 关系代词有：who, whom, whose, that, which等。 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 t

2、he man who/that wants to see you? 他就是你想见的人吗？ He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。 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. Please pass me the book whose （of which） cover is green. 3）which, that所代替的先行词是事物的名词或代词，在从句中可

3、作主语、宾语等。例如： A prosperity which / that had never been seen before appears in the countryside. The package （which / that）you are carrying is about to come unwrapped. 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 occasions w

4、hen （on which h） one must yield. Beijing is the place where（in which h） I was born.Is this the reason why （for which h） he refused our offer?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 / when / in which） he was born. He is unlik

5、ely to find the place （that / where / in which） he lived forty years ago. 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. Ill never forget the days when I worked together with you. 判断改错： （ ） This is the mo

6、untain village where I visited last year. （ ） I will never forget the days when I spent in the countryside. （ ） This is the mountain village （which） I visited last year. （ ） Ill never forget the days （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

7、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 whichD. the one 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，

8、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 bought last month. The house, which we bought last month, is very nice.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. My house, which I bought last year, has got a lovely garden. Th

9、is novel, which I have read three times, is very touching. 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. Liquid water changes to vapor, which is called evaporation. 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。

10、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. Do you remember the day on which you joined our club?ur 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, smok

11、ing 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 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 2）The weather turned out to be very good, _ was more than we could expect. A. w

12、hatB. whichC. thatD. it 3）It rained hard yesterday, _ prevented me from going to the park. A. thatB. whichC. as D. it 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

13、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）. 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. 。 As is known, smoking 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。 18.9 关系代词that 的

14、用法 1）不用that的情况 a） 引导非限定性定语从句时。例如： （错）The tree, that is four hundred years old, is very famous here. b） 介词后不能用。例如：We depend on the land from which we get our food. We depend on the land that/which we get our food from. 2） 只能用that作为定语从句的关系代词的情况 a）在there be 句型中，只用that，不用which。 b）在不定代词，如：anything, nothi

15、ng, the one, all, much, few, any, little等作先行词时，只用that，不用which. c）先行词有the only, the very修饰时，只用that。 d）先行词为序数词、数词、形容词最高级时，只用that。. e）先行词既有人，又有物时。例如： All that is needed is a supply of oil. Finally, the thief handed everything that he had stolen to the police.二、关于非限制性定语从句1. 引导限制性定语从句时，关系代词which可以与that互换；但引导非限制性定语从句时，只能用which。 例1She heard a terrible noise, _ frightened her. A. that B. which C. what D. who 例2She h
