英语语法里定语从句什么时候该用什么引导词
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,在从句中所起作用如下: Is he the man who/that wants to see you? 他就是想见你的人吗?(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在句中作主语) 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) 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)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? 2)that代替关系副词 that可以用于表示时间、地点、方式、理由的名词后取代when,where,why和"介词+ 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.他父亲在他出生那年逝世了. He is unlikely to find the place (that / where / in which) he lived forty years ago.他不大可能找到他四十年前居住过的地方.
我告诉你:
只有引导词同时作为定语从句的动词宾语时(不包括介词宾语),才不用引导词。
这个要看定语从句修饰的名词在句子中的成分
有that、which、who、whom等,当修饰限制的是人的时候,引导词用who,whom,that;
当修饰限制的是物品的时候,引导词用that,which;
且which一般用来引导非限制性定语从句
就这些,希望能够帮到你
