定语从句（Ⅲ）——“介词+ 关系代词”引导定语从句
要点一　“介词+ 关系代词”引导的定语从句
关系副词when，where，why 引导定语从句时，它们也可用“介词+ 关系代词（which / whom）”代替。
在“介词+ 关系代词”引导的定语从句中，关系代词只能用which 或whom，不可用that 或who。先行词指物时用which，先行词指人时用whom。
（ 1）介词选择的三原则：一先二动三意义。
一先：根据先行词的搭配习惯来确定。
二动：根据从句中谓语动词的搭配习惯来确定。
三意义：根据从句所表达的意义来确定。
【误区警示】
表“所属关系”或“整体中的一部分”时， 常用... of which/ whom 引导定语从句。
（ 2）介词可后移，此时关系代词可省略（省 略时，介词必须后移）。
【误区警示】 　
有些含有介词的固定动词短语一般不能将介词单独放在关系代词前，如listen to，look for，care for，hear from，hear of， take care of 等。
（3）“名词/ 代词/ 数词 +of + 关系代词” 引导的定语从句通常是非限制性定语从句，该结构在定语从句中一般作主语。
（4）“介词+whose”在定语从句中作定语， 修饰其后的名词。
单句语法填空
（1）I remember
the day 　　　　 which I settled in China.
