2025年中考英语定语从句知识点：介词+关系代词

　　7.介词+关系代词

　　★该结构的关系代词只有两种即 介词+which（指物） 介词+whom（指人）

　　★该结构介词的选用原则：

　　(1)根据定语从句中谓语动词的习惯搭配

　　This is the book on which I spent $ 8.

　　This is the book for which I paid $ 8.

　　(2)根据先行词的搭配习惯

　　I remember the days during which I lived there.

　　I remember the day on which I graduated from university.

　　(3)根据整个句子所表达的意思来决定

　　The colorless gas without which we can’t live is called oxygen.

　　(4)英语中为了强调某一名词，不定式前面也可以加上关系代词

　　Here is the money with which to buy the piano.

　　She is the right person on whom to depend

　　注意：

　　①如果介词后移，关系代词可以省略

　　The person (whom/who/that) you will write to is Todd.

　　②有些含有介词的动词短语介词不能提前如look for/after; take care of; send for; hear from/of/about deal with等

　　This is the baby that you will look after.
