介词+which/whom结构的用法□安徽/王振祥在定语从句中，有时引导定语从句的既可以是where或when，也可以是介词＋which／whom。

其中，介词＋which／whom引导的定语从句的现象常令同学们无所适从，不知道该用哪个介词。

那么，介词从何而来呢？下面我们就此问题分析讲解一下。

一、当先行词在定语从句中充当介词宾语时，可使用介词＋which／whom的结构引导从句。

指物时，只能用which ；指人时，只能用whom 。

例如：She is the very girl with whom I went t o the conference last week.她就是我上周一同去开会的那个女孩。

He made a telescope through which he could observe the stars.他做了个望远镜，用其观察星座。

但是，若该介词与其前的动词是一固定词组，则通常不拆散该词组，该介词仍位于定语从句的句中或句末。

此时，指人时，可用who或whom ；指物时，可用which或that ，且多可省略。

例如：This is the girl ( who / whom ) they have taken good care of for over a year.这是他们已精心照料一年多的那个女孩。

（take care of 为固定词组，不可拆开）Skating is the sport ( which / that ) people go in for in winter.滑冰是人们冬季喜欢从事的运动。

（go in for 为固定词组，不可拆开）该结构既可引导限制性定语从句，也可引导非限制性定语从句。

例如：She is telling a story about Lei Lei, of whom ever one of our class is proud.她在讲述雷雷的故事，雷雷是我们全班同学都为之感到自豪的人。

定语从句which与when 定语从句which与when 导语：定语从句，一个简单句跟在一名词或代词后（先行词）进行修饰限定，就叫做定语从句。以下店铺为大家介绍定语从句which与when文章，欢迎大家阅读参考! 定语从句which与when 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 prosperitywhich / thathad 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 packagewhich / thatyou are carrying is about to come unwrapped. 你拿的包快散了。(which / that 在句中作宾语） 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，在非正式文体中that常被省略（正式文体中不可省略），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。 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。例如： （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） I'll 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.先行词在从句中作主、定、宾语时，应选择关系代词；先行词在从句中作状语时，应选 择关系副词。 例如：（对）Is this the museum which you visited a few days ago? （对）Is this the museum where the exhibition was held? 【定语从句which与when】

定语从句中的that和which两者均作关系代词，代替先行词在从句中充当一些成分，一般为主语或宾语，作宾语时可省略。

I like the cakes which / that / 省略we ate together.that能指代人和物，which只能指代物。

只能用which的情况：1、非限制性定语从句中Mary has a storybook, which she treasures very much.2、在介词之后（如把介词移后，则可用that）This is the book on which I spent 8 yuan.=This is the book which / that / 省略 I spent 8 yuan on.注意：定语从句中谓语动词是含有介词的动词短语时，介词应放在动词之后，不能拆开放在关系代词前。

This is the key which you are looking for. 物This is the baby whom you will look after. 人3、当主句中的主语被that修饰或that直接作为先行词时That dog which I found in the street belongs to Mary.I know that which you told me.4、在"those+复数形式的名词"结构中,其后的关系代词多用which You should grasp well those skills which may be used in the future work.5、一个句子中如有两个定语从句,第一个定语从句用了关系代词that,第二个从句中的关系代词宜用which;但在平行结构中,应重复同一个关系代词This is the book that you bought which you have lost.I have a house which is located on the hillside, which faces the south.6、如先行词和定语从句之间被其它较长的成分分隔,常用which Larry told her the story of the young airman which I narrated at the begi nning of this book.限制性定语从句中只能用that的情况：1、当先行词为all, much, little, none时We should do all that is useful to the people.2、当先行词为由any, every, some, no所构成的复合不定代词时Do you have anything that is important to tell me?3、当先行词被all, any, some, no, not, every, each, few, little, much等修饰时I have some books that are very good.There is little work that is fit for you.4、当先行词为序数词或被序数词所修饰时This is the first book that I bought myself.When you talk about interesting books, the first comes to my mind is Harry Potter.5、当先行词为形容词最高级或被形容词最高级修饰时The best that I could do was to apologize.The biggest bird that I caught is in the cage.6、当先行词既包含人又包含物时I won’t forget the things and the persons that I saw.7、当先行词被the very, the only, the last, the just, the same等修饰时This is the very book that I lost yesterday.The only thing that we could do was to wait.8、当先行词是疑问代词who，which，what或主句以这些词开头时Who is the woman that was praised at the meeting?Who that has ever worked together with him doesn’t admire him?9、在there be句型中There is a room that has two windows.10、当先行词为主句表语或关系代词为从句表语时Our school is not the one that it used to be.China is no longer the country that she was.最后请注意：关系代词在定语从句中作主语时，从句的谓语必须与先行词保持人称和数的一致。
