1.用在感觉动词see,watch,notice,look at,hear,listen to,feel等后,作为宾语补足语,动词不定式不带to。如:

We often heard them sing.我们常常听到他们唱歌。

I saw her walk into the headmaster's office.我看见她走进了校长办公室。

2.用在使役动词make,let,have等后,作为宾语补足语,动词不定式不带to。如:

What makes you think I'm a farmer?你怎么认为我是一个农民?

Now let me hear you play.现在让我听你演奏。

I'll have my brother repair the radio for you.我要让我哥哥给你修理收音机。

注意:感觉动词see,hear,watch,notice,feel,look at,listen to和使役动词let,make,have等用于被动语态时,动词不定式作为主语补足语则要带to。如:

She was heard to sing in the next room.有人听到她在隔壁房间里唱歌。

3.用在 had better,had best(最好), would rather(宁愿)等结构后,词不定式不带to。如:

I'd better go and look for him.我最好现在就去找他。

You'd best get there before lunch.你最好午饭前到达那儿。

We would rather wait till tomorrow.我们宁愿等到明天。

4.两个或两个以上句法功能相同的动词不定式并列使用时,通常只是第一个动词不定式带to,后面的动词不定式则不带to。如:

So he decided to go and get some medicine for his cough.因此他决定去买点咳嗽药。

They began to read and write.他们开始读和写。

5.用在“Will you

please+动词不定式”一类表示邀请或命令的句型中,动词不定式不带to。如:

Will you please bring me some chicken?请你给我带点鸡肉来好吗?

Will you please ask her to call me tomorrow?请你让她明天给我打个电话好吗?

6.用在由“Why…”或“Why not…”一类表示建议的句型中,动词不定式不带to。如:

Why not join us?(=Why won't you join us?)为什么不加入到我们当中来呢?

Why spend so much money?为什么花这么多钱呢?

7.用在助动词will,shall,would,do和情态动词can,may,must,need,dare等后,动词不定式不带to。如:

I can sing in English.我会用英语唱。

I think it'll fit me quite well before long.我想这(件大衣) 很快就会合身的。

Unfair!How dare you

say that?不公平!你怎么敢这么说?

注意:ought to,have to中的to不能少。dare和need用作实义动词时,它后面的动词不定式要带to。如:

The girl doesn't dare to swim in the river.这女孩不敢在河里游泳。

8.用在动词help后作为宾语补足语,动词不定式既可以带to,也可以不带to。如:

Will you help me repair my bike?请你帮我修理一下自行车好吗?

Li Ping often helps me(to)do my lessons.李平经常帮助我做功课。

9.用在do anything(nothing,everything)but或except一类结构后,动词不定式不带to。如:

Can't you do anything but ask silly questions?难道你只会提些愚蠢的问题吗?

There is nothing to do except wait until the rain stops.除了静候雨停之外别无办法

回答2:

固定搭配,在词组中to
是个介词,比如object
to
就是object
to
doing.只因为这个to是个介词。诸如此类的有好多,你得积累才行。
