(一)动词不定式的时态和语态。
请同学们完成下列表格。
根据上面的表格,你能给下列句子对号入座吗?
(1) You seem to know this.
I hope to see you again.
(2) I’m sorry to have given you so much trouble.
(3) He is known to have been working on the problem in the past few years.

1. To see you is glad.
2. I want to see you.

5. He is the man to see you.
6. I am glad to see you.
7. I went to see you.
8. He went so early as to see you.
二、课中研学:
(一)动词不定式的句法功能
1. 作主语:句子的谓语动词常用单数,其位置有以下两种:
(1)不定式置于句首。
To get there by bike will take us half an hour.
(2)用it作形式主语时,把真正的主语不定式置于句后。
It is difficult for us to finish writing the composition in a quarter of an hour.
It is stupid of you to deal with it this way.
2. 作表语:不定式可在be动词或其他连系动词后作表语,当主语部分出现实义动词do或
do的其他形式如to do,did等时,作表语的不定式常不带to。
The only thing to do is call her.
3. 作宾语:(1) I happen to know the answer to your question.
(2) 不定式作think, feel, find, believe等动词的宾语时,一般用it作形式宾语,
不定式置于补语之后。
如:I find it difficult to learn physics well.
4. 作补语:The doctor advised me to take more exercise.
We consider Tom to be one of the best students. (“动词+to be+名词”结构)
The book is believed to be uninteresting. (“动词+to be+形容词”结构)
5. 作定语:置于被修饰的名词或代词之后,与被修饰词之间主要表示以下两种关系:
(1)主谓关系。
The next train to arrive is from Harbin.
(2)动宾关系。
Would you please give me some paper to write on?你能给我一些写东西的纸吗?
6. 作状语:(1)作目的状语。
可用to, in order to, so as to, so/such…as to…引导。
I come here only to say goodbye to you.
(2) 作结果状语。
表示事先没有预料到的事,一般放在句子后面。
He searched the room only to find nothing.
(3) 作原因状语。
I am sorry to be late for the meeting.
(二)不定式省略to的情况
口诀:宾补省“to”11个,五看二听一感觉,三个使役紧跟着,一个帮助两均可,如若主动变被动,该“to”一定要带着。
(notice observe see watch look at / hear listen to / feel / have let make / help / + sb do sth)
I heard her sing an English song last night.
She was heard to sing an English song last night.
(三)to作为不定式符号和作为介词的辨别
(1) get/be used to doing sth 习惯于used to do sth过去常常
