hope, demand, suggest等动词不能后接 动词不定式作宾补。 ①I hope my son will be back soon. ②She advises us to have a discussion about it. ③She suggests that we (should) have a discussion about it.
5．定语
定式与被修饰的名词往往构成逻辑上的关系。如名词 为不定式的逻辑主语，构成主谓关系； 若名词为逻辑宾语， 则构成动宾关系； He is not the first employee to arrive at the office this morning. There will not be enough space to stand in on the earth I have some books for you to read. 2、作定语的不定式与所修饰的名词之间是动宾关系， 不定 式动词又是不及物动词时，应在该动词上加上一个介词，如; He has a nice pen to write with. He is looking for a room to live in. He is said the best way to travel by is on foot.

(完整版)动词不定式的用法总结
动词不定式的用法总结动词不定式在中学英语中应用非常广泛，一方面在句中可起名词、形容词或副词的作用，同时也可在句中作主语、宾语、定语、状语和宾语补足语。
接下来为大家提供了以下：动词不定式的用法总结一动词不定式的形式一般是to +动词原形，但to有时要省去。
而动词不定式在具体运用时用不用to，取决于谓语动词的用法。
现就以下几方面介绍如下。
一、不定式结构1. 带to的不定式结构能直接跟带to的不定式结构的动词主要有：want, ask, tell, hope, learn, try, decide, forget, remember, like, love, stop, go, come等。
如：I want to go to the movies with you.我想跟你一起去看电影。
Don’t forget to turn off the light before you leave.在你离开之前别忘了关灯。
注意：动词不定式的否定形式是在不定式前直接加not，即not to do sth.。
如：Dave told me not to wake up Kate.大卫告诉我别叫醒凯特。
2. 不带to的不定式结构以下几种情况使用不带to的动词不定式：(1)在固定词组had better之后。
注意：had better的否定形式是had better not do sth.。
如：You had better go home now.你最好现在回家。
It’s cold outside. You’d better not go out.外面很冷，你最好不要出去。
(2)在let, make, see, feel, watch, hear等感官或使役动词后，要跟不带to的动词不定式作宾语补足语。
如：I made them give me the money back.我迫使他们把钱还给我。
I didn’t see you come in.我没看见你进来。
初中英语动词不定式的用法小结
初中英语动词不定式的用法小结当我们要表达“想要做某事、需要做某事或决定做某事”时，就会出现两个动词连用的情况，这时应如何表达呢？我们自然会想到want to do sth．,need to do sth．和decide to do sth．等表达方式。
主要行为动词后面的动词都采用了”to+动词原形”的结构，我们把这种结构称为不定式（有时可以不带to）。
动词不定式没有人称和数的变化，在句子中不能做谓语，那么英语中的动词不定式都可以表示什么意思呢？有什么样的语法功能呢？下面就做一下介绍。
一、动词不定式在句子中作主语。
1. 不定式作主语时，谓语动词一般用单数，常采用it作形式主语，不定式后置的方式，特别是不定式短语较长时，这样可以避免句子的“头重脚轻”，即It+形容词/名词+to do sth．。
动词不定式作主语，谓语动词用第三人称单数形式。
例如：It is not easy to learn English well. 学好英语真不容易。
It is difficult to speak a foreign language well. = To speak a foreign language well is difficult.说好一门外语是困难的。
It is necessary to remember enough words. = To remember enough words is necessary. 记住足量的单词是有必要的。
2. 带疑问词的不定式短语作主语常置于句首，复合不定式结构作主语常置于句末。
如：How to make requests politely is important. 如何有礼貌地提出请求很重要。
Where to go is not decided yet. 要去哪里还没做出决定。
It's good for you to walk after supper. 晚饭后散步对你是有益的。

动词不定式的否定形式是“not+动词不定式”(not不与助动词连用)。
三、动词不定式短语具有名词、形容词和副词等的功能，可在句中用做多种句子成分。
1、主语：常置于句末，而用it代替其做形式主语。
例：To go in for sports helps youstay fit.(book4，L28)It helps you stay fit to go in for sports. It is dangerous to swim in the deep sea on your own.注：此句式中不定式逻辑上的主语可由for或of引出，逻辑主语由of引出时，表语的形容词为kind，nice，good，polite，clever，foolish，right，wrong等表示评价的形容词。
例：It's right of him to refuse the invitation1.(him为逻辑主语)2、表语：Our duty is to protect the enviroment.3、动词宾语：此种情况可按固定搭配或句式去记。
例：would you like to see my photos?Kevin planned to visit his uncle.(book4，L11)和plan用法一样的词还有：start，want，agree，hope，begin，decide等。
