语法解读( "介词+关系代词"引导的定语从句(

(1) 根据动词选择介词。有些定语从句中的介词本身是从句的一部分,这样的介词可位于关系代词前,也可位于关系代词后。例如:(

I don't know the foreigner with whom my teacher shook hands.(

=I don't know the foreigner(whom)my teacher shook hands with.(

但要注意:who和that不能直接位于介词后作宾语;有的短语动词是不能拆开的,因为这些介词存在于关系密切的固定短语中,常见的这类短语有look for, look after等。例如:(

This is the pencil that Ma Lili is looking for.(对)(

This is the pencil for which Ma Lili is looking.(错)(

(2) 根据先行词选择介词。介词和先行词之间构成习惯搭配,此时,介词一般位于关系代词之前,它和从句中的动词不存在逻辑或意义上的关系。例如:(

He stood by the window, through which he could see what was happening outside.(the window 是介词through的逻辑宾语)(

(3) 有时,"介词+关系代词"可转换为关系副词,这样的关系副词一般为when, why, where。例如:(

This is the house in which(=where)Chairman Mao once lived.(

Everyone knows the reason for which(=why)the High Dam was built.(

I still remember the day on which(=when)we visited the temple.(
