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.

He is looking for a room to live in. He is said the best way to travel by is on foot.

动词不定式用法不定式是动词的一种非限定式,它是不受主语的单复数、人称、时态、语态等的限定及影响的一种动词形式。
一、动词不定式的基本结构动词不定式的基本形式为:to+动词原形,有时可不带to。
不定式的否定形式是:not to+动词原形。
在句中除不能作谓语外,其他成分都可作。
如:主语、表语、宾语、宾语补足语、定语和状语等。
注意:不定式之前的to(又称为小品词)与介词to的功能不同。
介词to之后要接名词或代词的宾格,或相当于名词的短语作它的宾语;而不定式符号to的后面需要跟动词原形。
speak to him (to 是介词) 对他讲话to speak English (to 是不定式的小品词) 讲英语二、动词不定式的用法不定式在句中有各种作用,一般可归类为三种基本用法:作名词,作形容词,作副词。
(一) 不定式作名词的用法不定式起名词作用,在句子中担当主语、表语、宾语和宾语补足语。
⒈作主语名词用法的不定式和名词一样,可担任句子的主语。

To hear your voice is so nice.(=It is so nice to hear your voice.) 听到你的声音真高兴。
To speak English well is not easy for me.(=It is not easy for me to speak English.) 把英语说好对我来说并不容易。
To walk to school takes me twenty minutes.(=It takes me twenty minutes to walk to school.) 步行到学校我要花20分钟。
的句型中,it是形式主语,真正的主语是不定式;使用这种注意:在It is… to…”结构,可以避免句子的头重脚轻。

(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。
(3)在引导疑问句的why not之后。
Why not+不带to的不定式是Why don’t you do的省略,可以用来提出建议或劝告。
如:Why not study with us?为什么不和我们一起学呢?Why not take a holiday?=Why don’t you take a holiday?为什么不休个假呢?(4)不定式动词在介词but, except, besides后面时,如这些介词前有实义动词do的各种形式,则后接不带to的不定式,否则带to。
如:I have no choice but to accept the fact.除了接受这个事实我别无选择。
What do you like to do besides swim?除了游泳你还喜欢做什么?(5)为了避免重复,不定式可省去to。
如:I’m really puzzled what to think or say.对于想什么或说什么,我真的很困惑。
二、不定式的时态不定式常用的时态有一般时、完成时、进行时和完成进行时四种,常用的为前三种。
1. 一般时动词不定式的一般式表示不定式的动作或状态与谓语动词所表示的动作同时发生或在之后发生。
如:I plan to attend the meeting.我计划参加这次会议。
2. 完成时不定式的完成式表示不定式的动作发生在谓语动词表示的动作之前。
如:I am sorry to have kept you waiting.很抱歉让你久等了。
3. 进行时不定式的进行式表示不定式的动作与谓语动词所表示的动作同时发生。
如:They are said to be working hard.据说他们工作得很努力。
4. 完成进行时不定式的完成进行式表示不定式的动作在谓语动词之前已经发生,并且一直进行着。
如:He is said to have been working in that factory for twelve years.据说他已在那家工厂工作12年了。
三、动词不定式在句中的作用1. 作主语如:To live is to work.生活就是工作。
To save time is to lengthen life.节约时间就等于延长了人的生命。
不定式结构作主语时,现代英语倾向于采用it作形式主语,而把不定式结构后置的形式。
如:It is important for students to study English.学好英语对学生来说是很重要的。
2. 作定语(1)不定式作定语,要放在它所修饰的名词或代词的后面。
如:I have nothing to say on this question.对这个问题我无可奉告。
(2)如果不定式是不及物动词,后面就应有必要的介词。
如:Give me a piece of paper to write on. 给我一张纸写字。
(3)有些名词常可用不定式作定语。
如:Our teacher had no time to think about rest.我们老师根本没时间考虑休息一下。
3. 作宾语I wish to be a college student.我希望成为一名大学生。
有的及物动词要求跟复合宾语(宾语+宾语补足语)。
如果其中的宾语是不定式短语,则必须将形式宾语it 放在宾语的位置上,而将不定式短语(真正的宾语)放在宾语补足语之前。
如:I find it useful to learn English well.我发现学好英语很有用。
4. 作宾语补足语动词不定式作宾语补足语是动词不定式用法的一个重点,学习时要注意以下三种情况。
(1)作动词ask, like, tell等的宾语补足语时,动词不定式符号to不可以省略。
如:He asked me to talk about English study.他请我谈谈英语学习。
(2)作使役动词let, have, make以及感官动词feel, hear, see, watch等的宾语补足语时,动词不定式符号to 要省略。
如:The teacher made him say the word like this.老师让他像这样说这个单词。
(3)作动词help的宾语补足语时,动词不定式符号to 可以带,也可以不带。
如:Could you help me (to) carry the heavy box?你能帮我搬这个重箱子吗?5. 作状语动词不定式及其短语具有副词的特性,可在句中作状语。
(1)作目的状语。
如:He stopped to have a rest.他停下来休息。
(2)作结果状语。
如:He woke up to find everybody gone.他醒来发现大家都走了。
(3)在某些表示喜、怒、哀、乐等的形容词后作原因状语。
如:I’m sorry to hear your grandma is ill.听到你奶奶生病真遗憾。
(4)在带有enough或too的句子里作状语,表程度。
如:He is old enough to go to school.他到了上学年龄了。
(5)强调动词不定式所表示的目的时,动词不定式可用in order to或so as to +动词原形,so as to不用于句首。
如:The bus stopped so as to pick up passengers.公共汽车停下来以便接乘客。
