attributive clauses intrduced by ____________________________________
a prepsitin + which/whm
Presentatin
在限制性定语从句中，除了用常见的关系代词或关系副词来引导定语从句外，当关系代词which，whm在定语从句中作介词的宾语时，从句可由“介词+which/whm”引出。
1. The man t whm yu spke is a teacher.2. He is a learned man with whm we are familiar.
当先行词是表人的名词或代词时，可由“介词+whm”引导从句。
1. The city in which she lives is far away. 2. The English play in which my students acted at the New Year’s party was a great success.
当先行词是表事物的名词或代词时，可由“介词+which”引导从句。
在“介词+关系代词”结构中，如何准确地选择介词呢？
This is the bk _____ which I gt the stry.
由于句意含有“从……”的意思，所以用介词 frm。
确定介词原则一：根据主从句之间的意思确定所需介词。
This rad will take me t the place ____ which I belng.
根据大意，从句意为“我属于的地方”。根据短语“belng t”可知空格处应填 t。
确定介词原则二：根据从句动词、形容词等构成的短语确定所需介词。
Jack is the very persn ________ I will turn when in truble.
据题干大意，从句意为“我遇到困难可以求助的人”。“求助”即“turn t”，又因先行词指人，故答案为 “t whm”。
The sng ften takes me back t the day when the accident happened. The sng ften takes me back t the day _____ which the accident happened.
据第一句可知，第二句中which用来指先行词“the day”，在从句中意为“在这天”，故填介词“n”。
确定介词原则三：根据先行词确定所需介词。
“介词+关系代词”结构往往可以和关系副词互换。
1. I’ll never frget the day when I jined the league.
2. This is the huse where I lived tw years ag.
3. There are many reasns why peple like traveling.
when =表时间的介词(in, n, at, during等)+which
n which (=n the day)
where =表地点的介词(in, at, n, under等) +which
in which (=in the huse)
why=表原因的介词 fr+ which
fr which (=fr the reasns)
1. I met the child (whm) I lked after ten years ag.我遇到了十年前我照料过的那个孩子。2. This is the pen (that/which) yu are lking fr.这是你正在找的钢笔。
定语从句的谓语如果是以介词结尾的动词固定短语，则不可把介词移至从句之首，如 hear frm，lk after， lk fr等。
另外，当关系代词作动词的间接宾语时，用t或fr。
1. Wh is the girl (that) he gave the flwer t?
2. The lady (whm/that) I wrte the pem fr was my sister.
用适当的关系词填空。I am sure she has smething ________ yu can learn frm. All the bks _______ Bb has just bught will be dnated t the children.This is the first bk __________ he has read. This is the very bk __________ belngs t him. They talked abut the schls and teachers _________they had visited. Wh is the man __________ is standing there?

relative clause (定语从句)关系词只能用which 不可用that的情况：1. 引导非限制性定语从句Ftball, which is a very interesting game, is ppular all ver the wrld.2. 关系代词之前有介词的。This is the huse in which he nce lived.
