初中英语语法总结(动词不定式)
初中英语知识点总结：动词不定式
初中英语知识点总结：动词不定式动词不定式在英语中，不充当句子谓语的动词，叫作非谓语动词。
由于非谓语动词不受主语的限制，没有时态和语态，所以又叫非限定动词。
非限定动词有三种形式：动词不定式；动名词和分词。
1、动词不定式（1）动词不定式的构成和性质动词不定式是一种非谓语动词，所谓非谓语动词就是不能作谓语的动词。
正因为如此，它不受主语的人称和数的限制，没有人称和数的变化，但它具有动词的某些特征，可以带宾语和状语构成不定式短语。
其构成是：“to + 动词原形”，否定式是“not to +动词原形”。
to是不定式符号，无词义。
（2）动词不定式的用法动词不定式除了不能作谓语外，可以作主语、表语、宾语、宾语补足语、定语和状语。
①作主语To learn English well is not easy.To drive fast is quite dangerous.不定式作主语时常常用it作形式主语，不定式放在谓语之后以上两个例句可以写成：It is not easy to learn English well.It is quite dangerous to drive fast.这种用法可以归纳成这样一个句型：It is (not) + 形容词+ (for sb.) to do sth.It is very expensive for me to buy a car.It is very difficult for a child to do that job.有些形容词之后跟of + 名词（代词宾语）+不定式。
如：It is very kind of you to say so. It is very good of you to come.②作表语。
如：My job is to teach English. The first thing is to ring him up.③作宾语。
如：She wanted to ask you a question. He forgot to turn off the light. We decided to hold a class meeting.常见的可以用不定式作宾语的动词有：like, love, begin, start, try, ask, prefer, hate, find等，有些形容词可接不定式，这种不定式也可作宾语。
最全面英语动词不定式的用法归纳整理总结
动词不定式的归纳总结动词不定式是由“to+动词原形”构成的，否定形式为“not to+动词原形”构成的，这里的to没有词义，只是为了构成不定式的一种符号，是非谓语动词形式的一种，动词不定式在句中不能独立作谓语，除了不能作谓语以外，其他成分都可以作，因此，在句中可以作主语、表语、宾语、定语、状语和补足语。
❶ 动词不定式做主语：这种情况一般要改成it作形式主语的形式，后接不定式，为了避免头重脚轻。
●“It is+形容词+for sb.+to do sth.”意为“做某事对某人来说是…的”中句中的形容词多为描述性的词语，不对人或物的品格进行评价，如difficult, easy, hard, inportant, dangerous, inpossible等。
eg To learn English is very important for me 对我来说学英语很重要。
=It is very important for me to learn English.For you to make more friends is a good plan. 广交朋友是个好办法。
= It's a good plan for you to make more friends.●“It is+形容词+of sb.+to do sth.”意为"做某事对某人来说是…的”。
其中句中的形容词用于描述人的性格、品质, 如：kind, good, nice, right, wrong, clever, careless, polite, foolish 等。
eg It was stupid of him to press the emergency button. 他按了紧急按钮，这真愚蠢。
❷ 本单元我们主要学习动词不定式作宾语的用法：现就动词不定式作宾语的用法介绍如下：●谓语动词＋动词不定式，此类动词很多，常见的有：want, like, wish, hate, prefer, hope, continue, manage, try, ask, offer（主动提出）, start, forget, promise, mean, pretend（假装）, intend（打算）, begin, attempt（试图）, decide, learn, desire （渴望）, agree, care, choose, determine（查明）, undertake（承担，承诺）,expect 等eg Some students hate to study English. 有些学生不喜欢研读英语。

初中英语动词不定式用法小结
初中英语动词不定式用法小结【1 】动词不定式是动词的一种非谓语情势,又叫非谓语动词,它没有人称和数的变更,在句子中不克不及做谓语;它由“to+动词本相”组成,这里的to是动词不定式符号,本身没有词义,其否认情势常在to前加not;因为它仍保持动词的特色,可以有本身的宾语和状语,还可以带疑问词和由for引出其逻辑主语等形成动词不定式短语;不定式或不定式短语具著名词.形容词和副词的特点,在句子中可作主语.表语.宾语.宾语补足语.定语和状语等句子成分.为使同窗们更好地控制其用法,现总结如下：一.动词不定式作主语动词不定式作主语时,为防止句子的头重脚轻,经常应用it作为情势主语,而真正的主语动词不定式后置.如要解释动作的履行者,可在不定式前加for引诱的短语;但假如表语是nice, kind, clever 等描写动作履行者的性情.品德的形容词时,则应在不定式前加of引诱的短语.经常应用句型:It +be+adj./n.+(for/of sb.) to do sth./It takes sb. some time to do sth.二.动词不定式作宾语一些动词,如want, decide, hope, ask, agree, choose, learn, plan, need, teach, prepare,等,常接动词不定式作宾语.当动词不定式作宾语时,假如后接宾语补足语,经常应用it作情势宾语,而把真正的宾语放在宾语补足语之后.应留意有些动词后面可接不定式作宾语,也可接动名词作宾语,但所表达的意义不合.罕有的有：（1）stop to do sth.停滞正在做的事,去做另一件事;stop doing sth. .停滞正在做的事（2）go on to do sth. 做完一件过后,持续做另一件事;go on doing sth.持续做统一件事（3）remember/forget to do sth.记住／忘却去做某事;remember/forget doing sth. 记得／忘却做过某事三.动词不定式作定语动词不定式作后置定语时,与被润饰的名词逻辑上有动宾关系.假如动词不定式是不及物动词时,则要带上与之搭配的介词,组成及物动词短语.动词不定式作后置定语经常应用于“have/has ＋某事＋to do”或“enough＋名词＋to do”“It’s time to do sth.”等构造中.四.动词不定式作宾语补足语有些动词,如tell, ask, want, invite, teach, like, call等可接带to的动词不定式作宾语补足语,组成tell/ask/want /call/invite sb. to do sth.构造.应留意动词不定式作使役动词和感官动词的宾语补足语时应省去to,在自动语态中应加上to.这些动词可归纳为“一感(feel),二听(listen to, hear),三让(let, make, have,,四看(look at, see, watch, notice),半帮忙(help)(即在动词help后面作宾语补足语时,to无关紧要)”.尚有口诀帮忙记忆：“感使动词真奇异,to在句中像魔鬼,自动句中to分开,自动句中to回来.”(let不必于自动语态)五.动词不定式作状语动词不定式作状语重要用来润饰动词,暗示目标,成果或原因.为了强调目标,有时可以把动词不定式放在句首,或在不定式前加in order或so as.经常应用构造有too + adj./adv. + to dosth.等.六.固定句式中动词不定式的用法在固定句式中对不定式的考核罕有的有：had better (not) do sth./W ould you like to do sth.?/Why not do sth.?/W ould you please (not) do sth.?等.动词不定式专项练习题：一.单项选择.1._______ is difficult to work out the maths problem.2.W e decided _______ at the end of this month.3.They have no paper_______.A.to writeB.to write withC.write onD.to write on4.Let him _______ a rest.

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(to do)是初中英语课的一个重点，也是中考要考查的一个项目。
接下来，小编给大家准备了动词不定式的用法总结,欢迎大家参考与借鉴。
动词不定式的用法总结动词不定式属于非谓语动词的一种形式，很多同学经常把它和谓语动词混在一起，掌握起来有困难。
下面我们对动词不定式的用法做简单归纳，帮助同学们记忆：一、动词不定式在句子中不能充当谓语，没有人称和数的变化。
二、动词不定式是由“to+动词原形”构成(有时可以不带to)。
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。

助动词除be和have外，没有不定式形式。
动词不定式在语法功能上可作主语、宾语、表语、定语和状语。
2．不定式的用法1)不定式结构作主语1.Te get contact with his family in Taiwan made him extremely happy since they separated more than 40 years ago．2.To finish that task in such a short time is really a challenge．在上述情况下，如果不定式较长，显得头重脚轻，则可由代词让作形式主语(形式主语it不可由that或this等其他代词代替)，而将不定式放到后面。
如：1.It made him extremely happy to get contact with his family in Taiwan since they separated more than 40 years ago．2.John admitted that it is always difficult for him to be on time．不定式结构所表示的动作是谁做的，即不定式的逻辑主语，通常可以通过for sb. to do sth. 结构表达：1.It is quite important for us to read good books during a general review．2.It is not difficult fot those talented students to pass the exam.在某些形容词(如careless，clever，considerate，foolish，good，impolite，kind，naughty，nice，silly，stupid等)作表语时，不定式后可以加of来引导出其逻辑主语：1.It is very kind of you to tell me the truth．2.It is stupid of him to do such a silly thing．2)不定式作宾语不定式作宾语有两种：一种是及物动词后直接跟带to的不定式，另一种是“及物动词+疑问词+带to的不定式。
及物动词+带to的不定式结构:只能跟动词不定式的动词，常见的有: afford，agree，aim，appear，ask，believe，care，claim，decide demand，desire，determine，expect，fail，happen，hesitate，hope，intend，learn，long，manage，offer，pretend，promise，prepare，refuse，seek，swear，undertake，want，wish等。
1.He managed to solve the complicated problem.2.The stranger offered to show me the way.3.Mr. Smith undertook to build a new plant in South Africa.动词+疑问代(副)词+不定式：这类动词常见的有advise，decide，find out，forget，inquire，know，learn，see，regard初中英语语法总结，remember，teach，tell，understand，wonder等。
常见的疑问代(副)词有: what，when，where，which，how，whether等。
1.He does not know when to start.2.Y ou can decide whether to continue or to stop.3.I will show you how to deal with it.有时，不定式可由it代替，而把不定式放到后面去。
这可以用这一结构表达：动词(如find，think，consider，feel等)+it+ 形容词+不定式。
1.She considers it necessary to make friends with him.2.We find it difficult to finish all the homework before 9 o’clock.3)不定式做表语一种情况为主语是不定式(表示条件)；表语也是不定式(表示结果)：1.To see is to believe.2.To work means to earn a living．另一种情况为主语是以aim，duty，hope，idea，job，plan，problem，purpose，thing，wish等名词为中心的短语，或以what 引导的名词性从句，不定式表语对主语起补充说明作用：；例如：1.His aim is to study abroad in the near future．2.The most important thing is to negotiate with them about the price．3.What I want to say is to forget all the unhappy experience．4)不定式作定语不定式结构作名词词组修饰语主要有三种类型：第一种，被修饰的名词词组是不定式的逻辑宾语。

例如：1.Mary needs a friend to play with．2.That girl has nothing to worry about．3.They have a strict teacher to listen to．4.Although the film had been on for ten minutes，I still was not able to find a chair to sit on．第二种，被修饰的名词词组是不定式的逻辑主语；例如：1.Have you got a key to unlock the door?2.The action to be taken is correct．3.There is nothing to be gained by pretending．第三种，被修饰的名词词组是不定式的同位结构。
这类名词通常是表示企图、努力、倾向、目的、愿望、is算、能力、意向等意义的名词：ability，attempt，effort，impulse，inclination，wish等。
例如：1.Her daughter will make an even bigger effort to please her．2.I have no wishto quarrel withyou．3.Neither of them had any inclination to do business with Mary.5)不定式作状语不定式结构在句中作状语通常都能转换为限制性状语从句。
例如作原因状语：1.They are quite surprised to see the great changes taking place in the area．2.They are quite surprised because they see the great changes taking place in the area．3.He was lucky to arrive before dark．4.He was lucky because he arrived before dark．作目的状语：1.She raised her voice to be heared better．2.She raised her voice so that she could heard better．3.We went via Heidelberg to miss the traffic jam．4.We went via Heidelberg so that we could miss the traffic jam．作结果状语：1.The French football team played so successfully as to defeat the Brazilians．2.The French football team played so successfully that they evendefeated the Brazilians．3.He got to the station only to be told the train had gone．4.He got to the station and was told that the train had gone．不带to的不定式的使用动词不定式通常带to，但在有些搭配中不带to，在另一些搭配中可带to可不带to。
归纳起来，以下情况下使用不带to不定式：1) 在can／could，/may／might，will／would，shall／should，must，need，dare等情态动词之后，动词不定式不带to。
2)在表示感觉意义的动词，如see初中英语语法总结，feel，watch，notice，smell，hear，observe等后，或是表示“致使”意义的动词，如have，let，make等后，动词不定式不带to。
例如：1.I often heard him say that he would study hard．2.I must have him see his own mistakes．但是，当这类结构转换为被动语态时，后面的不带to不定式一般转换为带to不定式。
