Module6 At one with nature 定语从句（介词+关系词） Step1: 情境导入 定语从句在前边两个单元已经学习过了，学生已经比较熟悉了，所以在这先对定语从句来一个基本用法的总结 Step2: Have a Look 1. These terraces were built by the local Zhuang and Yao people, to whom Guangxi is home. 2. Building the terraces therefore meant that they could increases the areas in which they could grow rice. 3. What is most significant is the way in which people have worked in harmony with nature. 4. This forms clouds from which rain falls down onto the mountain terraces. 5. These terraces still mean a lot to the local people for whom traditions hold much value. Step3： 介词+关系代词”引导的定语从句 一、基本用法  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。 The man to whom you spoke is a teacher. The little girl is reading a book, in which there are many cartoons.  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. 关系副词when，where，why可用“介词＋which”来代替。关系副词实际上是介词＋先行词。其中 when=表时间的介词（如：in，at,on,during等）+which； Where=表地点的介词（如：in，at,on,under等）+which Why=表原因的介词（如：for）+which   I still remember the day on which I came here.   This is the house in which I lived last year. There are many reasons for which many people like travelling.   3. Whose 也可以用of+关系代词替换 They live in a house, whose door opens to the south. They live in a house, the door of which opens to the south. They live in a house , of which the door opens to the south. 2、 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   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   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, ____I cannot see clearly.
