我将永远忘不了李先生离开的那一天。Isthisthecarforwhichyoupaidahighprice?（payfor）这是你花大价钱买的车吗?Thisisthepolicemanwithwhommyfathereverworked.（myfathereverworkedwith）

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。Therethechildrenhadagardeninwhichtoplay.（很正式）=Therethechildrenhadagardeninwhichtheycouldplay.（正式）=Therethechildrenhadagardentoplayin.（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+of+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。Hehasthreesons，oneofwhomisadoctor.他有三个儿子，其中一个是医生。Thereare50studentsinmyclass，allofwhomarehard-working.

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lookafter，lookfor，carefor，takecareof，hearof等。SheisthegirlwhomIamlookingafter.（after不能提前）她就是我照顾的那个女孩儿。（3）“介词+which/whom”（=whose）在定语从句中作定语，修饰其后的名词。Hehaswrittenabook，thenameofwhichIhaveforgotten.=Hehaswrittenabook，ofwhichthenameIhaveforgotten.=Hehaswrittenabook，whosenameIhaveforgotten.他写了一本书，书名我忘了。Thiskindofbookisforchildrenwhosenativelanguage（=thenativelanguageofwhom）isChinese.这种书是给母语是汉语的儿童看的。单句语法填空theday
