定语从句which和where区别

　　在我们的学习时代，大家都没少背知识点吧？知识点就是掌握某个问题/知识的学习要点。掌握知识点是我们提高成绩的关键！以下是小编为大家整理的定语从句which和where区别知识点，希望对大家有所帮助。

　　一、区别

　　关键是看从句中的动词。

　　1）如果是及物动词（顾名思义，就是必须要接物做宾语的动词，或能用做被动的动词），则表明从句缺宾语，修饰物用which.

　　2）如动词是不及物（顾名思义就是不需要接物做宾语的或要接宾语时前面必须要加介词的，即用介宾的动词），则说明从句不缺宾语，可能是状语(或介宾）。表地点用where.时间用when.

　　二、例句

　　1）This is the town which I wanted to visit most.

　　这就是我曾经最想参观的城镇。

　　由于定语从句中谓语部分的动词visit缺少宾语,因此填入的关系词要充当它的宾语,故用关系代词which。

　　2）This is the town where I was born.

　　这就是我出生的城镇。

　　定语从句“I was born”不缺少主语和宾语,而是缺少地点状语,故用关系副词where,这里where充当地点状语,修饰was born。

　　3） Literature is the place where the past meets the present to contemplate the future.

　　在文学作品里,过去与现实交汇,以思考未来。

　　这里,先行词place表示地点,而且定语从句中不缺少主语和宾语,需要的`是一个地点状语修饰meets,因而,此处用where来引导定语从句。

　　4） In fact, there are now so many deer that some are being sent to places which would like to return this kind of deer to the wild.

　　事实上,现在鹿群数量过多,以至于有些鹿被送到能使其回到野外的一些地方。

　　这句话中,先行词places是表示地点的名词,但是由于定语从句中缺少主语,所以用关系代词which来引导,而不使用关系副词where来引导。

　　1、语法作用：

　　“介词＋关系代词”在从句中主要起关系副词的作用，即在定语从句中充当状语：

　　（1）表示地点，时间和原因的“介词＋which”分别相当于where，when，why。

　　I have found the book in which the names of all the early satellites are mentioned.（SEFC 2A L. 55）（＝I have found the book. The names of all the early satellites are mentioned in it.）

　　The earth on which／where we live is a planet.

　　I”ll never forget the day on which／when I joined the League.

　　I know a wood in which／where you can find roses.

　　Is there any reason for which／why you should have a holiday？

　　（2）way后常用that代替in which，也可省略that。

　　I really don”t like the way that he talks.

　　That was the way in which the old lady looked after us.

　　Do it the way I showed you.

　　2、“of＋which”起形容词的作用，相当于whose（用来指物），其词序通常是“n.＋of which”。

　　They live in a house whose door／the door of which opens to the south.

　　He”s written a book whose name／the name of which I”ve com- pletely forgotten.

　　3、可引导限制性定语从句和非限制性定语从句

　　There is a rocket by which the direction of the satellite can be changed.（SEFC 2A L. 55）

　　We carefully studied the photos，in which we could see signs of plant disease.（SEFC 2A L. 55）

　　4、介词的选择（选择介词时须考虑下列情况）

　　（1）介词与先行词的习惯搭配

　　There is no way in which it could be brought back to the earth.（SEFC 2A L. 55）（in与way是习惯搭配）

　　（2）介词与定语从句中的动词，形容词的习惯搭配

　　These are the wires with which different machines are connected.（be connected with是习惯搭配）

　　The author with whom all of us are familiar will visit our compa-ny.（be familiar with是习惯搭配）

　　（3）同形的先行词，或定语从句中的动词，形容词表示不同的含义时，要根据其含义选用不同的介词。

　　I can”t remember the age at which he won the prize.

　　That is the age in which people live in peace and happiness.

　　age在前句中意为“年岁”，与at搭配；在后句中意为“时期”，与in搭配。

　　（4）复杂介词须保持其完整形式，常见的复杂介词有on the top of，in the middle of，in front of，in spite of，at the back of，because of等。

　　We took a photo of rocket，the length of which was about 30me- tres.（SEFC 2A L. 55）

　　Sound is a tool by means of which people communicate with each other.

　　They marched through the square，in the middle of which stood a monument.

　　（5）短语动词中的介词不可与动词分开提至关系代词前。常见的短语动词有listen to，look at，depend on，pay attention to，take care of，look into，break into，get rid of，take part in，make use of，take hold of，catch hold of，catch up with，get along with，look forward to等。此时可用which，who，whom或that，也可将他们省略。

　　（误）This is the girl of whom he will take care.

　　（正）This is the girl whom he will take careof.

　　（6）当介词与定语从句中的动词或形容词联系紧密（但不是短语动词）时，介词也可放在动词或形容词的后面。但当介词与从句中的动词或形容词联系不紧密时，则需将介词置于关系代词前。比较：

　　The space station which we drove to was in the desert.（SEFC 2A L. 55）

　　I”ll never forget the day in which I joined the Party.

　　后句中的in若置于句尾则有“孤零零”之感，这时宜将介词置于关系代词前；而前句中的to则可后置。

　　5、关系代词的选择

　　用于介词后的关系代词只有which，whom，前者指物，后者指人。

　　There are many research stations on the earth in which outer space is studied.（SEFC 2A L. 55）（which指代research stations）

　　We questioned the pilot，from whom we learnt that no other planes had been seen.（SEFC 2A L. 55）（whom指代the pilot）
