Unit6 “介词+关系代词”引导的定语从句学案 2022-2023学年高中英语外研版必修第一册

必修一 M6 “介词+关系代词”引导的定语从句 一.关系代词的确定 “介词+关系代词"可以引导限制性定语从句，和非限制性定语从句。在此结构中，先行词指人时关系代词用whom,不可以用who或that；先行词指物时关系代词用which,不能用that。 但如果介词后置，则不受这种限制，限制性定语从句中的关系代词还可以省去，尤其在口语中。 e.g. Do you know the girl to whom our teacher is talking? =Do you know the girl (that/who/whom) our teacher is talking to? The school in which my friend once studied is very famous. =The school (that/which) my friend once studied in is very famous. 二.介词的选取 “介词+关系代词”结构中介词的选用： 1.根据上下文要表达的具体意思来确定介词。有些句子的先行词完全一样，这时，需要根据句子所要表达的意思选用不同的介词。 e.g. This is the pilot with whom my brother has worked for ten years. This is the pilot by whom my son was saved. 2.根据定语从句修饰的先行词的习惯搭配来确定介词。 e.g. Do you still remember the day on which we met for the first time? 3.根据定语从句中某些词或短语的习惯搭配来确定介词。有时候，这个介词可能就是作定语从句谓语的短语动词的一个固定介词，如choose from中的from等。 e.g. Is this the car for which you paid a high price? In the dark street, there wasn't a single person to whom she could turn for help. 三. "介词+关系代词”的特殊用法 1.有些固定的动词短语在定语从句中作谓语动词时，该动词短语中的介词一般不提至关系代词前，常见的此类动词短语有look for, listen to, look after, take care of等。 e.g. This is the watch for which I am looking. This is the watch which/that I am looking for. 2.介词in，on，at，for等与关系代词which一起引导定语从句时，有时可用相应的关系副词when，where，why等替换。 e.g. The reason for which (=why) he refused the invitation is not clear. Great changes have taken place in the city in which (= where) I was born. 3.the way(方式，方法)后定语从句的关系词：the way 作先行词，后接定语从句时，①若关系词在从句中作状语，则用in which或that,关系词也可省略；②若关系词在从句中作宾语、主语等，关系词用which/hat，且关系词在从句中作宾语时也可省略。 e.g. The way (that/ in which) he treats his children is very good. The way (which/ that) you told me yesterday doesn't work. Exercise 1: 1.The study suggests that the cultures we grow up in influence the basic processes by ________ we see the world around us. 2. This is the computer _________ which I spent 3,000 yuan. 3.The two things about/of _________ he was not sure were the grammar and some of the idioms. 4.Creating an atmosphere _______ which employees feel part of a team
