定语从句 定语从句 定语从句 定语从句（Attributive Clauses）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。  2. 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，在从句中所起作用如下： 　 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/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 　　它们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 before 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） 3. 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。 when, where, why 　 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 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？  4. 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 mountain village where I visited last year. （错） 　 I will never forget the days when I spent in the countryside. （错） 　 This is the mountain village (which) I visited last year. （对） 　 Ill never forget the days (which) I spent in the countryside. （对） 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. where　B. that　 C. on which　 D. the one 例2. Is this the museum ____ the exhibition was held. A. where　　B.
