The old man ( ) they are talking about is a teacher.
The cat ( ) the dog is hunting for is Tom’s.
I like playing with the boy ( ) eyes are brown.
The fish ( ) body is red is from Africa.
老师咱们能不做题么，人与人之间的信任呢？
whose
who/that
whom/who/that
which/that
whose
whose
2.3. 只用“that”的情况
三大原则
1.说法绝对：先行词出现绝对性的描述，如唯一的(the only), 每个人(everyone), 每件事(everything),所有的(all),没有一个(none), 任何事(anything), 任何人(anyone)
2.数字常考: 当先行词前有序数词时，如 the first, the second, 其中the last，最后的也属于这种情况
3.最高级：先行词前有形容词最高级修饰时，也只能用“that”
此外：当先行词是人和物一起的时候，关系代词也要用that
又来？
This is the only book ( ) I can find.
This is the best book ( ) I have ever read.
Is there anything ( ) you don’t understand
The boy and his dog ( ) are walking along the street have lost their way.
3.关系副词及其用法
where: I remember the school where we had spent 3years.
when: Do you still remember these days when we were students.
why: Can you tell me the
reason why he leave me.
关系副词在从句中作状语
4.关系代词与关系副词的选择
I know the reason why he left home.
I forget the reason that he had told me.
(2) I still remember these days when we were best friends.
I still remember these days that he had forgotten already.
(3) This is the school where we had
left a good memory.
This is the school that was
destroyed in 2006.
我一定是听了假课，这又是什么东西？？？
来来来！不要松懈了，趁热再来几道题。
非限定性定语从句
1.区别：限定性定语从句是对先行词进行修饰说明的，是必要信息。
非限定性定语从句是对主句信息的补充说明。
The man who is standing under the tree is Mr. Wang.
Obama, who was the president of the US, loves his daughter.
原来是这样！
2.结构：
限定性定语从句关系词和主句之间不分开
非限定性定语从句常常用逗号单独隔开，且关系词用which，who，whom，whose, 关系代词的选择与前面判断限定性定语从句中关系代词的方法一致。此外，which可以指代主句的全部内容。
注意：that作关系词时前面不能有逗号。
Tom, who is a student, is my
neighbour.
He had won the first prize, which
surprised me a lot.
例题：
1. This car, ( )is dyed red, is Smith’s.
2. The boy, ( ) we all likes, is named Tom.
3. The Chairman’s daughter, ( ) name is Ann, gave me a patient smile.
4. The CEO, ( ) has earned a lot of money, is my father.
5. He had killed his father, ( )
surprised me a lot.

本堂小结
请同学来自己总结一下
定语从句
1.结构
2.关系词：关系代词与关系副词
3.关系代词和关系副词的判断
4.限定性定语从句与非限定性定
语从句
二.关系词
1.关系词的作用
He is a boy whom beautiful girls like
He is a boy/beuatiful girls like a boy
不要慌，且让老师娓娓道来
判断定语从句中到底是要选择关系代词还是关系副词，关键在于：
去掉要填的关系词后，如果从句依然完整，则使用关系副词，如果缺少主语宾语而使得句子不完整，则使用关系代词
He is a good student who likes reading books.
I know the reason why he came to my home.
He still remember the cliff where he jumped. (不及物动词)
谢谢！
