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。

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。

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(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。

动词不定式用法动词不定式没有人称和数的变化，在句中不能独立作谓语。
但动词不定式具有名词、形容词和副词特征，在句中可以作主语、宾语、宾语补足语、定语、表语和状语等多种成分。
另外，动词不定式具有动词特点，可以有自己的宾语和状语，组成动词不定式短语。
动词不定式的肯定形式是to＋do；其否定形式是not to＋do。
下面以动词不定式在句中的作用来予以详细说明。
1．作主语可以直接作主语。
如：To see is to believe．但在英语中，常用it作形式主语，真正的主语即动词不定式放在后面。
如：It's wrong to play tricks on other people．It's our duty to keep our environment clean and tidy．点击规律：动词不定式在句中作主语时，常放在It is ＋adj．（形容词）＋to do sth．或It is ＋n．（名词）＋to do sth．句型中，it仅作形式主语。
2．作宾语a．want，decide ，agree等动词后面跟并且只能跟不定式。
如：We agreed to start early．She wants to be a doctor．b．love，like ，begin，start，hate ，prefer等词后面可以接不定式。
点击规律：上述动词后面除接不定式外，还可以接动名词，意思无很大区别。
提示板：like doing指经常性动作，而like to do指一次性的动作。
如：I like swimming，but I don't like to swim now．我喜欢游泳，但我现在不想游。
c．stop，forget，remember，go on ，try等词或短语后面可以接不定式。
点击规律：上述动词后面接不定式和接动名词意思大不相同。
提示板：1）stop to do sth．：停止一件事，去做另一件事。
stop doing sth．：停止正在做的事。
例句：When the teacher came in，the students stopped talking；when he came out，the students stopped to talk．当老师走进来时，学生们停止说话；当老师走出去时，学生们又开始说话。
2）思考：forget，remember，go on，try等词或短语后面接不定式和动名词用法有何区别？d．在find／feel＋it＋adj．＋to do sth．句型中，it是形式宾语，真正的宾语是后面的动词不定式。
如：The man downstairs found it difficult to get to sleep．I feel it easy to recite the text．点击规律：某些动词或短语后面既可以接动词不定式作宾语，又可接动名词作宾语，二者用法上的区别可以通过造句子加以区分，如上面stop例句。
3．作宾语补足语a．tell，ask，want，order，teach，invite，warn，wish，help，get，wish，help等词后面常接不定式作宾补。
如：I tell him not to go there by bus ．Edison's mother taught him to read and write．b．let，make，have，see，hear，feel，watch，notice后面接不带to的不定式作宾补。
如：The boss makes them work 16 hours a day．I heard her sing in the next room．提示板：若变成被动语态，在上述结构中，不定式符号to要加上。
如：They are made to work 16 hours a day by the boss．She was heard to sing in the next room．4．作定语：放在被修饰的名词、代词后面例句：I have a lot of work to do．The doctor said he could do nothing to help the boy．点击规律：动词不定式若在句中作定语，常放在被修饰的名词、代词之后。
提示板：如果动词不定式和前面所修饰的词构成动宾关系，若动词是不及物动词，切记不要忘掉介词。
如：I have a small bedroom to live in．Have you got some pens to write with？5．表语：放在连系动词be后面例句：His wish is to become a scientist．The first important thing is to save the soldiers' lives．当务之急是抢救战士们的生命。
点击规律：动词不定式在句中作表语时，通常对连系动词前面的名词进行诠释说明。
6．作状语a．目的状语：放在go，come，use，live，in order等词后面。
如：I come to see you．He runs fast in order to get there in time．b．原因状语：放在sorry，glad，surprised，disappointed，excited等词后面。
如：I am glad to see you here．I am sorry to trouble you．c．作结果状语。
如：Some of the apples are hard to reach．The room is large enough to hold 1000 people．7．与what，who，whose，when，where，how等疑问词连用，作宾语、宾语补足语、主语等。
如：I don't know what to do next．（宾语）He taught us how to use the computer．（宾语补足语）It's still a question how to get there．（主语）【模拟试题】（答题时间：30分钟）一. 选择填空：1.
