定语从句 （3） ——“介词 + 关系代词”引导的定语从句1 “ 介词 + 关系代词 ” 引导的定语从句（1）由“介词 + 关系代词”引导的定语从句主要用于正式文体，在非正式文体中通常将介词放至句末。 This is the man t whm I referred. 我指的就是这个人。This is the man（whm） I referred t. 我指的就是这个人。（2）关系副词 when，where，why 引导定语从句时，也可用“介词 +关系代（which/whm）”代替，其中的关系代词只能用 which 或whm，不可用 that 或 wh。先行词指物时用 which，先行词指人时用 whm。
That is the day when （=n which） he was brn. 那就是他出生的日子。 That is the huse where（=in which） he lived. 那就是他住过的房子。That is the reasn why（=fr which） he must aplgise.那就是他必须道歉的原因。 ［词汇复现］（3）介词选择的三原则：一先二动三意义。① 一先：根据先行词的搭配习惯来确定。② 二动：根据从句中谓语动词的搭配习惯来确定。③ 三意义：根据从句所表达的意义来确定。I will never frget the day n which Mr. Li left. （n the day） 我将永远忘不了李先生离开的那一天。Is this the car fr which yu paid a high price? （pay fr）这是你花大价钱买的车吗 ? This is the pliceman with whm my father ever wrked. （my father ever wrked with） 这就是曾和我父亲一起工作的警察。（4）在很正式的文体中，“介词 + 关系代词”引导的定语从句可简化为“介词 + 关系代词 + 不定式”结构。
There the children had a garden in which t play. （很正式）=There the children had a garden in which they culd play. （正式）=There the children had a garden t play in.（口语） 在那儿孩子们有个可以在里面玩耍的花园。【误区警示】（1）“名词 / 代词 / 数词 +f+ 关系代词”通常引导非限制性定语从句，在定语从句中一般作主语，表示所属关系，或者整体中的一部分。He has three sns，ne f whm is a dctr.他有三个儿子，其中一个是医生。 There are 50 students in my class，all f whm are hard-wrking. 我们班有 50 名学生，所有人学习都很刻苦。（2）在定语从句中，有些含介词的短语动词不可拆开使用（短语拆开后含义发生变化），如 lk after，lk fr，care fr，take care f，hear f 等。 She is the girl whm I am lking after. （after 不能提前）她就是我照顾的那个女孩儿。
（3）“介词 +which/whm”（= whse）在定语从句中作定语，修饰其后的名词。He has written a bk，the name f which I have frgtten. =He has written a bk，f which the name I have frgtten. =He has written a bk，whse name I have frgtten. 他写了一本书，书名我忘了。 This kind f bk is fr children whse native language（=the native language f whm） is Chinese. 这种书是给母语是汉语的儿童看的。
