定语从句先行词怎么用

修饰定语从句的先行词有哪些，如何使用呢~

定语从句放在先行词后面。定语从句分为限定性定语从句和非限定性定语从句。引导定语从句的词有关系代词that、which、who、which、whose和关系副词where 、when,关系代词和关系副词是引导词,在定语从句中担当某一成份。
1、先行词指物时,关系代词用that 或which(在句中作主语或宾语)。
如:China is a country which / that has a large population.
The computer game which/ that he is playing is his favorite.
2、先行词指人时,关系代词用(who)作主语或宾语,whom (作宾语),whose (作定语),that (作主语或宾语)。如:
The man who is mending the machine has been retired.
This is the policeman who/ whom they were talking about yesterday.
I like the girl whose mother is an actor.
注意:下列情况下关系代词只用that 而不用which 或who。
3、先行词是指物的不代词,如:all, little, few, much, none, anything, nothing, everything等时。如:I didn't understand the words all that he said.
4、先行词由最高级、序数词以及any, very, only, all, no, just 等所修饰。如:This is the most beautiful place that I have been to .
5、先行词既包括人,也包括物。如:They always like to talk about the man and the things that they see on the road.
当主句是以which 或who 开头的特殊疑问句时。如:who is the man that opened up the lab.

扩展资料必须注意的问题
(1)关系词作主语时，从句中谓语的数。
(2)注意区别定语从句与强调句。
①定语从句中关系词作从句成分，复合句。
②强调it无意义，that/who不是引导词。
③强调it is/was和that/who后如果句子意思讲得通则是强调句，讲不通则不是。
It is the museum that/which we visited last year。(定语从句)
It was in the hotel that we stayed last night。(强调句)
(3)定语从句与同位语从句的区别。
①定语从句引导词被称为关系词，that充当主语、宾语、表语。有时可省略。
②同位语从句引导词被叫做连词，that不能充当任何成分，不可省。
Word came that their army was defeated。(同位语)
We expressed to them our wish that was the same as their。(定语)
(4)关系词在从句中省略的情况。
①关系词作宾语，前无介词时。
②关系词作表语。
(5)限制性定语从句与非限制性定语从句的翻译。
(6)关系词前有介词或复杂介词，关系词只能是which和whom。

在这个定语从句中，先行词要用whom，是因为定语从句的先行词要在主句中去找，它在从句中可
以作宾语，主语等成份。whom指代的是主句“The man met the workers”中的“the
workers”，是宾语，所以先行词要用whom。

在这个定语从句中，先行词不能用them。因为定语从句中的先行词只有两类，them不能作先行
词。
1、关系代词： that， which， who， whom， whose。
2、关系副词： when， where， why， how。
扩展资料：
定语从句中的先行词关系代词有主语、宾语、定语之分。要注意区分。
一般who做主语，或其宾格形式的whom做宾语(whom作宾语时可以省略），whose作为定语
（whose不可省略）。关系代词在从句中作主语、宾语、定语等，关系副词在从句中作地点状语
（where），时间状语（when），原因状语（why）。

定语从句（一）概念：He is the boy who often goes to school late. 先行词 关系词 定语从句关系代词： that， which， who， whom， whose（定语）注：在定语从句中作主语或作宾语。关系副词： when， where， why， how。注：在定语从句中作状语。 （二）原则： a. 定语从句必须紧跟在先行词后面，限制修饰先行词。b. 定语从句必须用关系词来引导。c. 关系词在定语从句中作一个句子成分。 （三）定语从句可分为两大类，即限制性定语从句和非限制性定语从句。�① 限制性定语从句是先行词在意义上不可缺少的定语，如果去掉的话，主句的意思就不完整，意义就表述不明。这种句型一般定语从句紧接先行词（不用逗号隔开）如：�I was the only person in my office who was invited.��② 非限制性定语从句。它与主句的关系不十分密切，只是对先行词起补充，说明的作用，也就是说即便去掉定语从句，句意也不受影响。主从句之间常用逗号分开，且非限制性定语从句不能用that来引导。This was the American Civil War, which lasted 4 years before the North won in the end.He was taken to another room, where he found a wounded boy, who was dying. （四）引导词：关系代词与关系副词She is the old woman whom I saw this morning.Mary is the girl whose parents work in Japan.Is this the key which you are looking for?October 1, 1949 is the day when New China was founded.This is the house where the great man was born.I don’t know the reason why she looks unhappy today.（1）who 指人，在定语从句中作主语/宾语，不能省略。His father is the person who will be most unhappy. 他父亲将是感到最不高兴的人。（2） whom指人，在定语从句中作宾语。Do you know Mr. Zhang whom they like very much? 你认识他们非常喜欢的张先生吗？（3）whose 指人，在定语从句中作定语。He is the only student in our class whose father is a policeman. 他是我们班唯一一个爸爸是警察的学生。（4）which指物，在定语从句中作主语或宾语。作主语时，指物可与that 互换；做宾语时可省略。如果作介词宾语，且介词提前，则不能省略，也不能替换为that。This is the magazine about which we were talking. =This is the magazine（which/= that）we were talking about. This is the room（which/ that）I painted last week.（作宾语可省略）（5）that指物/人，在定语从句中作主语或宾语。作主语时，指人可与who替换；指物可与which 替换。做宾语时可以省略。The book that（=which）cost me a lot of money is interesting.The hero that（=who）saved me from the fire is a PLA man.The book（that/ which）I bought yesterday is well written. 下列定语从句只能用that来引导：1. 先行词为形容词最高级所修饰This is the longest bridge that I have ever seen.2. 先行词为序数词所修饰I happened to be the thousandth guest that visited the great hotel.This is the first composition that he has ever written in English. 3. 先行词既包括人又包括物They talked of things and persons that happened in the school.He talked about the teachers and schools that he had visited.4. 主句是who或which开头的特殊疑问句中的定语从句Who is the man that came this morning? Which is the bag that you lost?5. 先行词为the only, the very, the last, the same所修饰 He is the very person that the police are looking for.This is the only thing that I can remember. 6. 先行词是everything, nothing, something, all, little, much, everybody等不定代词Tell us everything that you know, please.Is there anything that you don’t understand?7. 先行词被all, every, no, some, any, little, much修饰All that glitters is not gold.I’ve read all the books that you gave me. 只能用which，不用that 的情况：1. 在非限制性定语从句中。例如：The meeting was put off, which was exactly what we wanted.2. 定语从句由介词+关系代词引导，先行词是物时。例如：The thing about which he is talking is of great importance. （五）“介词+ 关系词”及关系副词when, where, why1. The box is full of bottles. He is standing on the box. →The box on which he is standing is full of bottles.The box where he is standing is full of bottles.2. This is the train. We work on the train. →This is the train on which we work. This is the train where we work.3. I know the reason. She did it for the reason. →I know the reason for which she did it. I know the reason why she did it.4. The man is our school master. You shook hands with the man just now. →The man with whom you shook hands is our schoolmaster.5. The pen is made in Shanghai. She is writing with the pen. →The pen with which she is writing is made in Shanghai.不能拆开的词组： look for / look after /take care of / put on / take off… （六）关系代词在从句中作主语，谓语动词的数与先行词保持一致。The student who is good at English studies hard.The students who are good at English study hard.对比：He is one of the students who are good at English.（英语好的不止他一人，他是他们中的一员）He is the one of the students who is good at English. （学生不止一人，他们中只有一人英语好） （七）as 作为关系代词，习惯上用于下列词组：the same....as such ...as as ... as， so…as1. Take as many books as you want.2. Here is so big a stone as no man can lift.3. He read such books as will make him wiser.4. The town is about the same distance from Nanjing as Yangzhou is.As 用于非限制性定语从句，常见以下句型：as you know, as we have seen, as is known to all, as anybody can see, as was expected, as we can imagine, as has been pointed out注意： as与which的用法区别：as与 which在非限制性定语从句中，都可指代整个主句，但as引导的从句可放在主句的句首, 句中或句尾， 而 which引导的从句只可放在主句的句尾As we have seen, oceans cover more than 70 percent of the earth.Oceans cover more than 70 percent of the earth, as we have seen.She was awarded a gold medal, which the whole family considered a great honour. （八）the same…as, the same …that 的区别This is the same bag as I lost yesterday. （相似的事物）I am wearing the same coat that I wore yesterday. （同一事物） （九）定语从句和同位语从句的区别： 定语从句相当于形容词作定语，对先行词加以限制或修饰，同位语从句相当于名词，对先行词加以补充或说明，连接词that在定语从句中充当某个成分，而that在同位语从句不充当句子成分。The promise that my uncle gave me made us happy.（定语从句）The promise that my uncle would give me a new bike made us happy.（同位语从句）The news that they had won came.（十）关系代词what和that, which的区别： 先比较下列句子中的what和that：He told us the things that he had seen. →He told us what he had seen.This is the words which I said. →This is what I said.可以看出what 实际上等于是 “the thing that（which）”， 即 “先行词+关系代词”。因此在句中如果已有先行词，则不能用what，而只能用that（which），如没有先行词，则用what。what是一个没有先行词的连接代词，连接名词从句，如：宾语从句，主语从句等。

　　被定语从句修饰的名词、代词称为先行词。我们可以这样认为, 之所以称它为先行词, 是因为修饰它的定语从句总是放在它之后, 先行词总是出现在定语从句之前, 而不同于普通形容词修饰名词时, 形容词位于名词之前。

　　A.限定性定语从句
　　限定性定语从句, 用来修饰和限定先行词, 与先行词间的关系非常密切, 它所修饰的先行词代表一个（些）或一类特写的人或物, 从句用来说明先行词的性质、身份、特征等状况, 如果去掉, 则意思含混不清。

　　（who引导的限定性定语从句, 修饰先行词a person。who在从句中作主语。） 医生就是照顾病人的人。
　　B．非限定性定语从句
　　1.非限定性定语从句的特点
　　非限定性定语从句起补充说明作用, 也不会影响全句的理解, 译为汉语时常常不译作定语, 而根据句意翻译为相应的其他形式的从句。对它与主句的关系不如限定性定语从句的关系紧密, 只是对先行词作些附加说明, 即使去掉,
　　主句的意思依然清楚。在非限定性定语从句的前面往往有逗号隔开, 如若将非限定性定语从句放在句子中间, 其前后都需要用逗号隔开。
　　C．限定性定语从句和非限定性定语从句的区别
　　限定性定语从句和非限定性定语从句在结构、用法及意义上差别很大。
