初三英语寒假专题——动词不定式(Infinitive)知识精讲 人教版+汤姆森
初三英语寒假专题——动词不定式（Infinitive）知识精讲人教版＋汤姆森【同步教育信息】一. 本周教学内容：寒假专题——动词不定式（Infinitive）同学们，寒假来到了。
这是我们休整总结的一个好时机。
在这一段时间里，我们对初中阶段经常出现，但同学们不易掌握的几个语法项目进行专项讲解。
今天我们的题目是动词不定式。
我们经常会遇到它，也经常会犯错误，今天让我们攻克这个难题。
一. 动词的非谓语形式我们都知道，动词在句子中做谓语。
如果把动词的形式稍做变化，还可以起到名词、形容词或副词的作用，在句中充当主语、宾语、表语、补语、状语等各种成分。
动词的这些变化被称为非谓语形式。
也就是说，除了谓语之外，其它成份都能充当。
动词的非谓语形式有三种：（1）动词不定式：to study（to+动词原形）（2）分词：studying（现在分词）studied（过去分词）（3）动名词：studying（形式与现在分词相同，相当于名词）动词的非谓语形式不随主语的人称和数的变化而变化；它仍具有动词的一般特征，可以带宾语、状语等构成短语；另外它也有时态的不同变化以及语态的变化。
今天，我们先来学习其中的一种，动词不定式。
二. 动词不定式的结构和功能：一般结构：to＋动词原形时态的变化：一般现在时：to write（to be written 被动形式）现在进行时：to be writing现在完成时：to have written完成进行时：to have been writing动词不定式能起到名词、形容词、副词的作用，充当谓语以外的各种成分，是最神通广大三. 动词不定式功能分类：（一）作主语：eg.1. To learn English is not an easy thing.学习英语不是一件容易的事。
2. It is our duty to learn the knowledge well.好好学习知识是我们的职责。

n.（动词）不定式;
adj.不定式的;
复数：infinitives
动词不定式（infinitive）：在语法中，动词不定式是指动词的一种不带词形变化从而不指示人称、数量、时态的形式。
它之所以被叫做不定式，是因为动词不被限定，或者说不被词形变化所局限。
不定式属于非谓语动词。
在外语学习的课程中，动词不定式的一般现在时被称作“词典用词”，因为它一般被用作词典中该动词的词头。
对于英语来说接不定式的单词多为“打算”“计划”“希望”等表示未来的动词。
同样与不定时表示不同的动词不定式表示正在进行，一般性或经常发生性的行为。
动词不定式可以作以上各种成分，但它毕竟是动词，所以有动词的属性。
动词不定式及其短语还可以有自己的宾语、状语，虽然动词不定式在语法上没有表面上的直接主语，但它表达的意义是动作，这一动作一定由使动者发出。
这一使动者称之为逻辑主语。

Negative infinitive:
A negative infinitive is formed by adding not or never immediately before the infinitive sign to . E.g: We decided not to buy that house. She wished never to see him again. (not/never to + the base of the verb) Ex: I promised to lend them some money. ( negative form) I promised not to lend them some money. She pretended to see me. (negative form) She pretended not to see me.
f) The bare infinitive usually appears after “ causative verb+object”. ( have, let, make, help, get, set, have, etc.) E.g.: 1.make /have/ let/help +sb +do sth. We can’t let this go on. He won’t have us criticize his work. They made me repeat the story. 2.get/set/leave + sb to do/doing sth. I can't get anyone to do the work properly. We left him to paint the gate. But when the causative verb occurs in the passive, the bare infinitive should be turned into a to-infinitive. E.g.: They made me repeat the story.
b) The bare infinitive is used to follow semi-auxiliaries. E.g.: You’d better have that bad tooth pulled out. I happened to be out when he called.
c) The bare infinitive is used to combine with such modal idioms as would rather, would sooner, would (just) as soon, may/might just as well, cannot but, cannot help but, etc, E.g.: I would rather listen to others than talk himself.
She wanted to be reassured. He did not care to disturb his roommate. (Passive voice) He did not care to be disturbed by his roommate.
Different aspect and voice used to denote different idea:
Infinitives commonly occur with to, but in some contexts it is necessary to use the bare infinitive, and in some other cases the infinitive sign is optional. a) The bare infinitive is generally used to follow the modals including need and dare. Modals: e.g: You must do as you are told. Who should come in but the mayor himself! Need: e.g: We needn’t stay here this evening. ( modal) Do we need to stay here? ( main verb) Dare: e.g: She daren’t go there alone. (modal) She doesn’t dare to go there. (main verb)
1. Grammatical forms
The infinitive has no tense distinctions, nor person or number contrast But they can be passive and take the simple, progressive, perfective and perfective progressive forms. E.g. I have a lot of work to do. (simple) She had no need to be worrying. ( progressive) He is said to have left Shanghai. ( perfective) The president was reported to have been flying across the Atlantic. (perfective progressive)
He is so marvelous that I can’t help but ______him.
a. to respect b. respect c. to respect on d. respect on
d) The bare infinitive is commonly used to follow rather than and sooner than, especially when rather than/ sooner than takes the initial position. E.g.: Rather than cause trouble, he left. Sooner than marry that man, she would earn her living as a waitress.
Passive voice of infinitive:
A passive voice is formed by to be +-ed, or to have been +-ed. E.g. The matter to be discussed at the meeting is a hard nut to crack. They were all waiting for the gate to be opened. Ex: She wanted to reassure. (Passive voice)

2. To-infinitive and barase) + infinitive
8.5 Verb+infinitive
8.1 Forms of the infinitive
There are two types of infinitive: to – infinitive and bare infinitive. The bare infinitive is just the infinitive without to, which is identical form with the base of the verb.
Besides, it is also used to follow had better, had best, do nothing but, do nothing besides, do nothing than, do nothing except, etc..
e) The bare infinitive can be combined with a main verb to form some fixed combinations such as: make believe let slip make do (with/ on) let go (of) let drop let (go) of/ leave go of let fall hear tell (of) let fly (at) (let…) go hang Ex: Use the above expressions to fill the blanks. 1. He did all that just to ______. 2. He’s born cadger---never _______an opportunity of getting something for nothing. 3. I didn’t have time to buy any food today. You’ll have to ____ the left-over cold meat from yesterday. 4. His uncle was said to have _______ this remark. 5. He picked up a stone, and _______the barking dog. 6.
