1、The Attributive Clause,定语从句,知识准备,什么是定语： 用来修饰名词或代词的词、短语、从句。 .,4.定语 修饰和限定名词和代词的词。通常由形容词，代词(多为形容词性物主代词），数词，介词短语，动词不定式，分词和从句（定语从句）来担当。 a kind girl, a book on the desk I have homework to finish. the fallen leaves the boy who is very smart,基本结构,He was holding onto a tree that grew against the wall.,主句: He

2、 was holding onto a tree. 从句：A tree grew against the wall.,还原,定语从句相当于一个形容词，跟在名词或代词后修饰该名词或代词。 1. 被定语从句修饰的名词或代词叫先行词。 2. 引导定语从句的词叫关系词。 关系代词：who, whom(作宾语成分）, whose, that, which 关系副词：when（时间）, where（地点）,why（原因）,名词/代词 + 定语从句,关系代词和关系副词的作用： 1、引导作用 2、替代作用 3、在定语从句中担当某个成分的作用 Eg: 1.Those who want to go please

3、should be ready. 2. Bill, who was my student , asked me questions.,关系词引导定语从句，同时指代先行词在 定语从句中充当的成分 所以先行词在定语从句中不再出现,也不用其他词代替,Bill is a boy who I teach him.,关系副词引导定语从句时，既引导定语从句，又在定语从句中充当状语。不能省略. 关系副词可转化为介词+关系代词结构。 1、When指时间，在定语从句中充当时间状语。 He told me the date when(on which) he joined the Party. 2、Where指地点

4、，在定语从句中充当地点状语。 This is the place where(in which) we lived ten years ago. 3、Why指原因，在定语从句中充当原因状语。 I know the reason why(for which) she was so angry.,1.This is the park (that )we visited last year. This is the park where we held a birthday party. 2.She wont forget the days (that )she spent on the islan

5、d. She wont forget the days when they stayed together.,关系副词when, where和关系代词that, which的区分。,同样是修饰一个地点，有时使用where，有时使用that/which；同样是修饰一个时间，有时使用when， 有时使用that/which。这主要看两点：一：先行词在从句中所作成分；二：是定语从句中的谓语动词是否是一个及物动词。,（1）This is the factory _ I visited last year. （2）This is the factory _ I worked last year. （3）

6、This is the factory _ produces all kinds of TV sets.,用关系副词和关系代词,where B. which C. whom D. whose 以上三个句子只有细微的差别，但答案却不同：做这种题时，要通过还原先行词,看先行词在定语从句中所充当的成分； 1）中是动宾关系，即I visited the factory.因此选which 2）中factory应在定语从句中作地点状语，即：I worked in the factory，因此选where。 3）中是作定语从句中的主语，即: the factory produces all kinds 不作

7、地点状语，因此选which,A,B,B,(1)Hangzhou is the place _ I went last summer. 2) He read the book _ his sister had told him about. 3) The reason _ Peter is so happy is that he passed the exam. 4) I remember the day _ my father died.
