课堂研讨
一、动词不定式分_______和___________两种。带to 不定式由_______构成，其否定形式为_______;不带to不定式与______同形。
二、不定式的用法 动词不定式在句中可作主语、宾语、宾补、表语 、定语、和状语。判断下列动词不定式的用法：
1.To learn English is not an easy thing . ( )
2.It is our duty to learn the knowledge well.( )
3.He wants to visit Nanjing . ( )
4.I expect you to write to me .( )
5.To see is to believe .( )
6.Is there anything toeat ?( )
7.My little sister is too young to go to school .( )
8.My job is to plant cotton .
9.I asked him to show me his new dictionary .( )
10.He has no house to live in ( )
三、注意几点
1.不定式作主语时，常用it 代替不定式结构，it被称为形式主语，作为句子真正主语的不定式后置。常用句型：It’s +adj./n.+for /of sb. +to do sth.形容词表示做事情怎样用for 引出不定式的逻辑主语；形容词表示人的特点或性质则用of引出不定式的逻辑主语。如：
It’s important _____us ____learn English well .
It’s very nice ______you _____help me .
___is hard to say .A.This B. It C.That
2. 常接不定式作宾语的动词有want,hope ,refuse ,would like,help,decide,wish,plan,等等。
The teacher decided _________a speech at that time.
A. giving B.to give C.give
3. 不定式作定语与被修饰的词是动宾关系，所以动词要用及物动词，如果为不及物动词则要接介词。
He is a man to depend on .(on不能省)
He has no house ____________
A. to live B.to live in C.live in
4. 常接不定式作宾语补足语的动词有want,ask ,tell,wish,would like ,get,encourge, allow,invite等。但在使役动词make ,let,have和感官动词see,hear,watch,notice,feel等之后，要把作宾补的不定式结构中的to省略。

A.sings B.sing C.singing
2)The teacher told the boys _________in the street.
A.not play B.not to play C.don’t play
3)The doctor often tells him_____________ more exercise

5) Linda was very sorry for being late. But the teacher’s smile made her _____better .
A feel B to feel C fall D to fall
5.疑问句+不定式
不定式可以和疑问词who ,what,which,why,when,how,where等连用，构成“疑问词+不定式”结构，通常用于 下列动词之后：tell,teach,know,wonder,learn,show,find,out,ask,understand等等。
1).We are going for a picnic tomorrow.I’ll call Wendy to make sure ____
A.why to start B.when to start C.what to start D.which to start
2). The worker is teachiing us _______ mend the chair .
A how B how to C what to D when
3) Nobody knows _____ do tomorrow .

6. find,think等动词之后接不定式+形容词作宾补中，常用it 作形式宾语，
把不定式放在后面。

A.take B.to take C.taking
8.多数动词后跟动词不定式或动名词作宾语，句意基本相同，但下面几个动词后跟动词不定式或动名词时 句意完全不同。
