用 介词,＋关系代词填空（英语题）

of whichfrom whomwith whomin whichwith whichin whichof whichof whom关系代词前介词选择三原则：一先,二动,三意义（重中之重）1。一先,即根据定语从句中介词与先行词的搭配关系选择。I never forget the day on which I came to this school。(on the day) 2。。二动,即根据定语从句中谓语动词与介词的搭配关系选择。This is the iPad on which I spent 3000 yuan。(spend money on sth。) 3。三意义,即根据定语从句的意义来确定介词。This is my pair of glasses,__without which__I cannot see clearly。1。“介词+关系代词”结构引导的定语从句中,关系代词只能用which（指物）或whom(指人) ,即：介词+which/whom。注意：当介词放在关系代词的前面时,用在介词后的关系代词不能省略。2。在限制性定语从句中,当介词置于定语从句的谓语动词之后时,可用that/which(指物)；that/who/whom（指人）作介词的宾语。且此处关系代词可以省略,特别是在口语中。如：（1) The man (who/whom /that )you spoke to is a teacher。（2）The city（which/that）she lives in is far away。注：通常介词放在定语从句中动词后,也可以放在关系代词前面,但有些特殊动词短语搭配不能拆分,介词只能放在动词后,如：look for,look after,pay attention to ,take care of ,look forward to,listen to等。不懂再继续问,
