Step1: 听暴风听力
Step2: 自主学习—定语从句
一、在复合句中，修饰某一代词或________ 词的句子，叫做定语从句；被修饰的名词
或代词叫__________词，定语从句放在先行词的________ ( 前/后)面。
请观察下列例句：1）Mary is a girl who/ that has long hair.
2) These are the trees which / that were planted last year.
3) The woman (whom/ that) they wanted to visit is a teacher.
4) I know the girl whose mother is a teacher.
5）This is the park where we held a birthday party.
归纳：1、定语从句的结构：先行词+ __________ + 句子
2、关系词分为关系______ 词和关系________ 词。
3、1) 指人的关系代词有：________ ________ _______
2) 指物的关系代词有： ___ ___ ___ _________
3) _________ 即可指人，也可指物，在定语从句中作定语。
4）关系副词有：___ _____ _________ ___ ________
二、请观察例句：1）The boy with whom John spoke is my brother.
2) We depend on the land from which we get our food.
归纳：当关系代词指人且前面有介词时，只能用________; 当关系代词指物且前面
有介词时，只能用________。
三、关系代词在定语从句中作主语时，定语从句中谓语动词的单复数应该与先行词一致。
先行词是单数时，谓语动词用______数；先行词是复数时，从句中的谓语动词用_______数。Eg: I have three good friends who ______ ( be ) from the USA.
四、关系代词与关系副词的用法区别
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：一是定语从句是否完整；二是定语从句中的谓语动词是否是一个及物动词。请比较以下句子：
1）This is the park that we visited last year.
2）This is the park where we held a bi rthday party.
3）That’s the date when we went to the college.
4）That’s the date that she won’t forget for ever.
及时训练：（ ）1. Is this the place ______ you were born?
A. wh ich B.where C.what D.that
（ ）2. Is this the place ______ some German friends visited last year?
A. which B.where C.what D. Why
【注意】有6种情况下关系代词只用that，请在P98用红笔划出来。
