解放军文职考试：“介词+关系代词which/whom”引导的定语从句

正式语体中，关系代词作介词宾语，常常把介词置于关系代词which/whom之前;非正式语体中，介词可置于从句末。介词的选择取决于其与作先行词的名词、代词的搭配或与定语从句中谓语动词的搭配。有时候需要兼顾先行词和定语从句中的动词。

　　【考例】Many people who had seen the film were afraid to go to the forest when they remembered the scenes______people were eaten by the tiger.(2005广东卷)

　　A.in which　　B.by which C.which　　D.that

　　此题中的介词取决于前面的名词scenes，构成in the scenes，故选A。

　　温馨提示：“介词+关系代词”引导的定语从句要和“介词+疑问代词”引导的宾语从句区别开。两种句子结构很相似，但亦有区别：“介词+关系代词”前面是名词或代词，而“介词+疑问代词”前面则是动词或形容词。

　　【考例】They way he did it was different ______we were used to. (2005江西卷)

　　A. in which　B. in that C. from what　D. from which

　　该题很容易让同学们误选D，把它看成“介词+关系代词”引导的定语从句。be different from是一形容词短语，what引导宾语从句作介词from的宾语，而不是from which引导的定语从句，故选C。
