6、词的选择，该结构主要从以下几方面考虑。(1) 从先行词跟介词的搭配出发I 'll never forget the day on which we worked together in the countryside.(把the day带入从句后，加on 才成立，即we worked together on the day in the countryside)The clever boy made a hole in the wall, through which we could see what was happening inside the house. (through w

7、hich即through the hole)(2)从定语从句中动词、形容词等对介词的搭配要求出发Do you know the girl _ whom the man talked just now?(talk后用to, with还是about,则根据先行词、定语从句中的动词talk考虑，此处用with或to比较好）The two things of which they felt pound were Jim's gold watch and Della's hair.（3）根据定语从句所表达的意义来确定介词In front of the house Tom is plant

8、ing a trede, under which he will be able to sit and read some day.特别提示(1) 如果含有介词的动词短语不能拆开，则不能转化成“介词+关系代词”结构，介词仍然放在动词的后面。常见的这类动词有：listen to, look at, depend on, pay attention to, take care of, look into, break into, get rid of, take part in , make use of, take/catch hold of, catch up with, get along

12、特殊句型：（1）"介词+关系代词"后接不定式短语作后置定语，相当于一个定语从句。He has a knife with which to defend himself. = He has a knife with which he can defend himself.先行词way后定语从句当先行词是way，意为“方法，方式”时，引导定语从句的关系词有in which, that和不用任何关系词这三种形式。I don't understand the way in which/that/- they worked out the problem.试比较以下两个句子关

13、系词的不同The way that/which /-he explained to us was not difficult to understand. ( 关系代词that/which在从句中作宾语）The way that/in which he explained the sentence to us was not difficult to understand.(关系词在从句中作状语，相当于in this/that way）典例I will tell you the way _ you can study English well, because I know the way _
