　　在复合句中，修饰某一名词或代词的从句叫定语从句。被修饰的名词或代词叫先行词，定语从句一般放在先行词的后面，引导定语从句的词被称为关系词。
引导定语从句的关系词有关系代词（在定语从句中作主语，宾语，表语，定语）和关系副词（在定语从句中作状语），常见的关系代词包括that， which， wh（宾格whm，所有格whse）等，关系副词包括where， when， why等。关系代词和关系副词放在先行词及定语从句之间起连接作用，同时又作定语从句的重要成分。
　　根据定语从句与先行词的关系，定语从句可分为限制性定语从句及非限制性定语从句。限制性定语从句紧跟先行词，主句与从句不用逗号分开，从句不可省去；非限制性定语从句主句与从句之间有逗号分开，起补充说明作用，如省去，意思仍完整。
1. that 既可以用于指人，也可以用于指物。在从句中作主语或宾语，作主语时不可省略，作宾语可省略。例如：Mary likes music that is quiet and gentle.玛丽喜欢轻柔的音乐。（that作主语）The cat（that）I put n the desk is blue.我放在桌子上的那件外套是蓝色的。（that作宾语）　
that 指人/物，作主语或宾语 (作宾语可省略）
A plane is a machine. It can fly.

注意：介词提前时只能用which 而不能用that 。

that和which在指物的情况下一般都可以互换，但在下列情况下，一般用which而不用that。
a.先行词为that，thse时，用which，而不用that。例如：What’s that which is under the desk？ 在桌子底下的那些东西是什么？b.关系代词前有介词时，一般用which，而不用that。例如：This is the rm in which he lives. 这是他居住的房间。c.引导非限制性定语从句，用which， 而不用that。例如：Tm came back, which made us happy. 汤姆回来了，这使我们很高兴
2. which用于指物，在句中作主语或宾语，作主语不可省略，作宾语可省略。
例如：The building which stands near the train statin is a supermarket.位于火车站附近的那座大楼是一家超市。（作主语）The film （which） we saw last night was wnderful. 我们昨天晚上看的那部电影很好看。（作宾语）

1. 当定语从句中含有介词，介词放在句末时，wh， that， which可省略，但介词在关系代词前时，只能用“介词+ which / whm”结构。例如：This is the huse in which we lived last year.这是我们去年居住的房子。Please tell me frm whm yu brrwed the English nvel.请告诉我你从谁那借的这本英文小说。
2. 含有介词的固定动词词组中，介词不可前置，只能放在原来的位置上。例如：This is the persn whm yu are lking fr. 这就是你要找的那个人。
3. that作介词的宾语时，介词不能放它的前面，只能放在从句中动词的后面。例如：The city that she lives in is very far away.她居住的城市非常远。
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，主句的意思就不完整或失去意义。这种从句和主句关系十分密切， 写时不用逗号分开。
非限制性定语从句和主句关系不很密切，只是对先行词作些附加说明，如果去掉，主句的意思仍然清楚。这种从句，写时往往逗号分开。
限制性定语从句和非限制性定语从句
My sister, wh is twenty, wrks in a bank.
The man wh came here yesterday has cme again.
whse 在定语从句中作定语，表示引导词与 whse 后的名词为所属关系。 whse多指人，也可指物，指物时可与 f which互换使用。
This is the bk whse cver is blue.This is the bk f which the cver is blue.
