Want/ask/ tell /order/ allow/ wish/beg/advise / call /invite +sb. to do sth.

7. 动词不定式省to的情况
一感feel
二听hear, listen to +sb. do sth.
三使have, let, make
四看see, watch, look at, notice
常考短语：hear/see/ make / let sb. do sth.
被动语态：Sb. be heard/ seen/made/let to do sth.（变成被动语态时补回to）
I often see him help others. He is often seen to help other by me.
二、动词不定式的句式：
1..动词不定式作主语，主语较长时，常用it作形式主语，而将真正的主语放在句。
It + is/was+adj.+(for sb.) + to do sth.
To learn English well is useful. = It’s useful to learn English well.学好英语是有用的。
To protect environment is important for us.
= It’s important for us to protect environment.对于我们来说保护环境是很重要的。
2. It is / was + adj.(kind / good/ nice/ clever) + of sb. +to do sth.
It’s very kind of you to help me. =You are very kind to help me你帮助我真是太好啦。
It’s very clever of you to do like that.=You are clever to do like that你那样做真的太聪明啦。
这个句型的形容词为表示人的品格，气质之类的词。
可以等于句型：sb. is / was + adj. +to do sth.
3. It takes ( took , will take ) sb. some time to do something. (做某事花费某人…时间)
4.. 主语+ find / think + it +形容词+ (for sb.) + to do
I find it easy to read English every day. 我发现每天读英语和容易的。

I think it very interesting to learn English. 我认为学英语很有趣。

5.不定式作表语表示主语的“职业、职责或性质”等

My dream is to be a teacher.我的梦想是当一名教师。
6.不定式作状语的用法

The question is simple for him to answer.（表程度）这个问题对他来说太容易回答了。
7. 动词不定式可以和疑问词who, what, which, when, how, where(why除外)等连用，构成不定式短语。
Can you tell me how to get to the post office?
I didn’t know what to do next.
How to learn English well is the question that we all want to ask.
The question is when to get there.
What to do 与how to do 的区别:
I don’t know what to do next?我不知道下一步该做什么。(What to do后没有sth.)
I don’t know how to use this machine.我不知道怎么样使用这部机器（how to do +sth.）
三、动名词（动词+ing）作用相当于名词。（可以作主语、宾语、表语和定语）
