教学目标：
掌握Unit 1语法定语从句
教学重难点：
掌握定语从句
（一）that和which在指物的情况下一般都可以互换, 但在下列情况下, 一般用that而不用which。（1）先行词为all, everything, nothing, something, anything, little, much 等不定代词时。I am sure she has something （that） you can borrow.
（2）先行词被all, every, no, some, any, little, much等修饰时。
I’ve read all the books that are not mine.
（3）先行词被序数词或最高级修饰时。
This is the first book （that） he has read.
（4）先行词被the only, the very, the same, the last修饰时。
This is the very book that belongs to him.
（5）先行词既有人又有物时。
They talked about the things and persons that didn’t interest me.
（6）如果有两个定语从句，其中一句的关系词是that，另一句用which。
Let me show you the book that I borrowed from the library which was newly open to us.
用正确的关系代词连接下列两个句子：
（1）The scientist is very famous in the world. We met her yesterday.
The scientist / who /whom/ that we met yesterday is very famous in the world.（2）The dress is new. She is wearing it.
The dress that / which / she is wearing is new.
（3）He is the kind person. I have ever worked with him.
He is the kind person that/ who/ whom/ I have ever worked with.（4）This is the best film. I have ever seen this film.
This is the best film that / I have ever seen.（二）whose
I know the person. His company produces new machines.
I know the person whose company produces new machines.
She is the engineer. Her work is considered to be the best here.
She is the engineer whose work is considered to be the best here.
whose 在定语从句中作定语，表示引导词与 whose 后的名词为所属关系。whose多指人，也可指物，指物时可与 of which互换使用。
This is the book whose cover is blue.
This is the book of which the cover is blue.
This is the person. Her story surprised everybody.
This is the person whose story surprised everybody.
The person was Ms King. Her designs were the best.
The person whose designs were the best was Ms King.
This teacher is liked by all the students. I work with her son. This teacher whose son I work with is liked by all the students.
The chair is being repaired now. The legs of the chair are broken.
The chair whose legs are broken is being repaired now.
whose从句可转换为“of +关系代词”型，如：
e.g. They live in a house whose door opens to the south.
They lived in a house, of which the door opens to the south.
They lived in a house, the door of which opens to the south.
【典型例题】一、用适当的词填空
1. All _____ can be done has been done.
答案：that that can be done部分是定语从句修饰all，先行词为不定代词只能用that引导。
2. Is that the only （first, very, best） book ______ he has ever read?
答案：that 先行词被the only, the very, the same, the last, the best 修饰时，只能用that引导。
3. Is there anything ______I can do now?
答案：that 先行词为不定代词只能用that引导。
4. She is the only student who_____ （know） it.
答案：knows 先行词为the only student，单数形式，所以用knows5. She is one of the students who____ （know） it.
答案：know 注意与上一题区别，这时的先行词为students, 复数，所以用know6. The number of people who_____ （want） to go to America____ （be） rising.
答案：want, is who____ to go to America定语从句修饰people,先行词为复数，所以填want; the number of意为“……的数目”，单数，所以这里用is。
二、单项选择

A. which B. that C. what D. as
