Book2A Unit1 动词不定式的用法
3. 作定语 4. 作表语 5. 作宾补 6. 作状语
动词不定式作主语，谓语动词用第三人称单数。 How to get enough money is still a question. To make a plan for our study is very important.
有时候为了保持句子平衡，常用it作形式主语， 放到句首，而将作真实主语的动词不定式放 到句末。
It will take a whole day to get there by car. It is important to make a plan for our study. It is impossible for me to finish the work in a week.
动词不定式作宾语常用于下列及物动词后： want, agree, decide, manage, wish, hope, ask, like, love 等等。
I have learned to drive the car.
He promised to come but he hasn’t turn up yet. He pretended to be reading when his mother came into his room.
2. 如果不定式作宾语而后面又有一个宾语 补足语，这时要用it作形式宾语而把这个 动词不定式放到补语后。 I feel it my duty to help you. I thought it impossible to finish the job in such a limited time.
He was the last one to leave school yesterday. We have much homework to do everyday.
动词不定式常放在系动词（be动词）后作表 语，有时也放在其他少数连系动词如： remain, seem, sound等后。
