英语定语从句知识和用法概述I 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 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：I like music (that/which)I can sing along with.（which / that在句中作宾语）The bag(that/which) you bought me is lost. （which / that在句中作宾语）4) that 和 what 当that引导定语从句时，通常用作关系代词，而引导名词性从句时，是个不充当任何成分的连接词。宾语从句和表语从句中的that常可省略。What只能引导名词性从句，用作连接代词，作从句的具体成分，且不能省略。例如：I think（that）you will like the stamps. 我想你会喜欢这些邮票的。What we need is more practice. 我们需要的是更多的实践。II. 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。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： Ill never forget the day when (on which) I joined the party.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？ III.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. 这是我去年呆过的山村。Ill never forget the days when I worked together with you.我永远不会忘记与你共事的日子 判断改错： （错）This is the mountain village where I visited last year. （错）I will never forget the days when I spent in the countryside. （对）This is the mountain village（which）I visited last year. （对）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例1变为肯定句： This museum is _ you visited a few days ago.例2变为肯定句： This is the museum _ the exhibition was held. 在句1中，所缺部分为宾语，而where, that, on which都不能起到宾语的作用，只有the one既做了主句的表语，又可做从句的宾语，可以省略关系代词，所以应选D。 而句2中, 主、谓、宾俱全，从句部分为句子的状语表地点，既可用副词where，又因 in the museum词组，可用介词in + which 引导地点状语。而此题中，介词on 用的不对，所以选A。关系词的选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词（who, whom, that, which, whose）； 先行词在从句中做状语时，应选择关系副词 （ where 地点状语，when 时间状语，why 原因状语） 。IV. 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，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. 这是我们上个月买的那幢房子。（限制性）The house, which we bought last month, is very nice.这幢房子很漂亮，是我们上个月买的。（非限制性）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. 查理?史密斯去年退休了，他曾经是我的老师。My house, which I bought last year, has got a lovely garden.我去年买的的那幢房子带着个漂亮的花园。This novel, which I have read three times, is very touching. 这本小说很动人，我已经读了三遍。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. 他似乎没抓住我的意思，这使我心烦。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。V. 介词+关系词 1）介词后面的关系词不能省略。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. 这是我两年前住过的房子。 This is the house where I lived two years ago. Do you remember the day on which you joined our club? 还记得你加入我们俱乐部的那一天吗？ Do you remember the day when you joined our club? . 关系代词that 的用法 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. 我们依赖土地获得食物。 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, nothing, 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. 所需的只是供油问题。 Finally, the thief handed everything that he had stolen to the police. 那贼最终把偷的全部东西交给了警察。EXERCISES1.
