課堂研討

一、動詞不定式分_______和___________兩種。帶to 不定式由_______構成，其否定形式為_______;不帶to不定式與______同形。

二、不定式的用法 動詞不定式在句中可作主語、賓語、賓補、表語 、定語、和狀語。判斷下列動詞不定式的用法：

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、注意幾點

1.不定式作主語時，常用it 代替不定式結構，it被稱為形式主語，作為句子真正主語的不定式后置。常用句型：It’s +adj./n.+for /of sb. +to do sth.形容詞表示做事情怎樣用for 引出不定式的邏輯主語；形容詞表示人的特點或性質則用of引出不定式的邏輯主語。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. 常接不定式作賓語的動詞有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. 不定式作定語與被修飾的詞是動賓關系，所以動詞要用及物動詞，如果為不及物動詞則要接介詞。

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. 常接不定式作賓語補足語的動詞有want,ask ,tell,wish,would like ,get,encourge, allow,invite等。但在使役動詞make ,let,have和感官動詞see,hear,watch,notice,feel等之后，要把作賓補的不定式結構中的to省略。

1)I often hear Tom ________in the next room.

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

A to take B taking C taken D take

4) The teacher often tells Jim and John _____]too much time playing video games

A not to spend B to not spend C don’t D doesn’t spend

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.疑問句+不定式

不定式可以和疑問詞who ,what,which,why,when,how,where等連用，構成“疑問詞+不定式”結構，通常用于 下列動詞之后：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 .

A where to B what to C how to

6. find,think等動詞之后接不定式+形容詞作賓補中，常用it 作形式賓語，

把不定式放在后面。

1)I find______very important to learn English well because it is an international langange now. A.it B.its C.that D.this

2)He found it hard ____ his class

A to catch up B catch up with C catch up D to catch up with

7.在 why not…? Will/Would you please (not)….? had better (not)…

等句型后用省略to的不定式。

A.giving B.to give C.give

A.take B.to take C.taking

8.多數動詞后跟動詞不定式或動名詞作賓語，句意基本相同，但下面幾個動詞后跟動詞不定式或動名詞時 句意完全不同。

(1) stop to do st
