动词不定式用法归纳
动词不定式用法归纳 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。 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．（Lesson 10）． 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.以下动词只能to do 作宾语。 attempt企图 enable能够 neglect忽视 afford负担得起 demand要求 long渴望 arrange 安排 mean意欲，打算 begin开始 expect期望 appear似乎，显得 determine决定 manage设法 cease停止 hate憎恨，厌恶 pretend假装 ask问 need需要 agree同意 desire愿望 love爱 swear宣誓 volunteer志愿 wish希望 bear承受 endeavor努力 offer提供 beg请求 fail不能 plan计划 bother扰乱；烦恼 forget忘记 prefer喜欢，宁愿 care关心，喜欢 happen碰巧 prepare准备 decide决定 learn学习 regret抱歉，遗憾 choose选择 hesitate犹豫 profess表明 claim要求 hope希望 promise承诺，允许 start 开始 undertake承接 want想要 intend想要 refuse拒绝 decide决定 learn学习 contrive设法，图谋 incline有…倾向 propose提议 seek找，寻觅 try试图 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。 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．下面的动词要求不定式做宾补：动词+宾语+动词不定式 ask要求，邀请 get请，得到 prompt促使 allow允许 forbid禁止 prefer喜欢，宁愿 announce

动词不定式作主语的三种方式
动词不定式作主语的三种方式 I 不定式作主语通常位于句首。如： ①To see is to believe．百闻不如一见。 ②To get up early is necessary．早起是必要的。 II 把引导词it放在句首作形式主语，而把真正的主语———动词不定式（短语）放在后面。如： ①It's not easy to work out the problem．计算出这道题不容易。 ②It is interesting to play with snow in winter．冬季里玩雪是很有趣的。 it作形式主语时，有三种情况： 1）常用形容词作它的表语。真正主语不定式通常有逻辑主语，一般用for短语来表示，即for sb．to do sth．（其中sb．就是to do的逻辑主语）。如： It's important for us to keep the water clean．保持水质清洁对我们来说是很重要的。 ［注意］for不能用of来代替，因为不能说：Y ou are important． 当表语形容词表示不定式的逻辑主语的性质或特征时，则不用for，而用of（sb．to do sth．）。如： It's very kind of you to say so．你这样说真是太好了。 （可以说：Y ou are very kind．） 2）有时也接名词作表语。如： It must be great fun to fly to the moon in a spaceship．乘宇宙飞船飞往月球一定很有趣。 3）it作形式主语时，还常用于“It takes（took ／will take）sb．some time（money）to do sth．”句型中。如： ①It took me more than an hour to do my homework yesterday evening．昨天晚上我做作业用了一个多小时。 ②It will take us a long time to walk there．步行去那儿要花费我们很长时间。 III．动词不定式与疑问词how，what，when，where，which等连用构成不定式短语，也可作主语。如： ①How to use the computer is the question．如何使用计算机是个问题。 ②Where to go has not been decided．去哪儿还没有定下来。 【巩固练习】选择正确答案填空。 1．It's important you walk after supper． A．of；to B．for；of C．to；to D．for；to 2．It's very kind you help me． A．to；of B．of；to C．for；to D．to；to 3．To make friends with them nice． A．is B．are C．be D．does 4． the meeting has not been discussed yet． A．Why to hold B．Where to C．When to hold D．Which to （Keys：1—4 DBAC）
动词不定式讲解
非谓语动词 一、英语句子需要遵循一个总原则：一个句子只能有一个动词。当一个句子必须要出现两个或两个以上的动词才能完整 表达一个意思时，为了不违法总原则，英语有四种处理方式： 1. 切分成两个或者多个句子 She is a girl. She likes English 2. 将一个谓语动词做主句，其余动词改成从句 She is the girl who likes singing. 3. 添加and, but, or, when, because, not only..but also, either..or 等连词变成并列结构 She got off the bus, but left her handbag on her seat. 4. 将其中一个动词变成非谓语动词形式 She got off the bus, leaving her handbag on her seat. 二、非谓语动词使用条件：一个句子当中，已经存在一个主句（谓语动词），又没有连词(and,but,or等)的情况下， 还有别的动词出现时，这时就要用非谓语动词 三、非谓语除了不能做谓语外，其他成分都可以做 不定式（to do） 四、非谓语动词三种形式分词现在分词（doing） 过去分词( done ) 动名词(doing) 五、非谓语动词解题技巧： 1. 判断是不是用非谓语动词（1.看有没有逗号 2.看有没有谓语 3.看有没有连词。要牢记英语中逗号不能连接两个 句子，一个句子如果没有连词只能有一个谓语） 2. 判断是主语和动词是主动还是被动关系 3. 判断时间, 确定非谓语动词和主句动词谁先发生，谁后发生 不定式的用法 不定式构成一般式完成式进行式 主动关系to do to have done to be doing 被动关系to be done to have been done 不定式动词和谓语动词发生的时间关系不定式的动作和谓语动作同时发生， 或发生谓语动作之后 he seems to know a lot 不定式的动作发生在谓语动 作之前 I regretted to have told you a lie. 不定式的动作和谓语 动作同时发生 I’m glad to be talking with you 不定式否定形式在to前加not. 即not to..... 不定式充当的成分主语，宾语，表语，定语，状语，宾补
英语语法之不定式及名词后加动词不定式
English语法之不定式及名词后加动词不定式 在English语法中，动词不定式是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。基本形式是to+动词原形，部分词和词组不带to也表达不定式。之所以叫做不定式，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，即不能单独作谓语。但它毕竟是动词，所以有动词的属性，也可以理解此类动词形式为不定式状态的动词。动词不定式及其短语有自己的宾语、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。 动词不定式可以作多种句子成分。 在外语学习的课程中，"动不式"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”“将要”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。 A.不带to的不定式有四种情况： 1、1、let, make, have等使役动词后。 例如： Let us go!出发 The boss made the child labors work the whole night.老板逼迫童工整夜 劳作 注意：这些情况在被动语态中，不可省to. 例如：The child labors were made to work the whole night. 2、would rather, had better后。
例如：You had better stay at home.你最好呆在家 3、w hy…/w hy not…后。 例如：Why not have a happy rest on Sunday? 不定式的否定式是not to do.. / never to do..，不带to的不定式的否定式是not do.../ never do.. 例如：His parents tell him never to drive after drinking.他的父母告诉他酒后严禁驾驶 4.感官动词see, watch, look at, hear, listen to, smell, feel, find，notice等后作宾语补足语。 例如: I saw her dance.我看到她在舞 除以上四种情况之外，都不得省略to B. 动词不定式的复合结构 动词不定式的复合结构是“for sb. to do sth. / of sb. to do sth.” for / of引出不定式动作的逻辑主语。这种结构在句子中可以作主语、宾语、表语、定语、状语等。不定式复合结构的介词用for还是of，主要决定于前面形容词的性质。一般说来，of前面的形容词是careful, clever, foolish, good, kind, nice, wise等，既说明人的特性，又说明不定式动作的特性。for前面的形容词是dangerous, difficult, easy, hard, heavy, important, interesting, necessary等，一般说明不定式动作的特性，不说明人的特性。 例如：

动词不定式用法讲解
动词不定式用法小结 动词不定式用法小结 动词不定式是一种非谓语动词形式，其结构为“to＋动词原形”，其中to不是介词，而是动词不定式的符号，称为小品词，动词不定式没有人称和数的变化。动词不定式和其后面的名词等构成不定式短语，在句子中可以用作主语、表语、宾语、补足语、定语、状语等。 一. 作主语例如： To be a doctor is hard. 做医生很难。 To learn English well is not easy. 学好英语不容易。 动词不定式（短语）作主语时，为了避免句子的头重脚轻，可以用“it”作形式主语，而把真正的主语－－动词不定式（短语）放在句子的后部。例如上面的句子可以表示为： It is hard to be a doctor. It is not easy to learn English well. 再如： It’s important to plant trees in spring. 如果动词不定式的动作是谁做的，可以在动词不定式前面加一个由介词for 引导的短语，称为不定式的复合结构。例： It’s good for us to read English aloud in the morning. 对我们来说每天早晨大声读英语是很有益的。 It is important for students to use English every day. 对学生来说每天使用英语是很重要的。 二. 作表语： 动词不定式（短语）作表语常用于系词be的后面。例： His work is to drive a car. 他的工作是开车。 My job is to feed animals. 我的工作是饲养动物。 Her ambition is to be a doctor. 她的理想是当医生。 三. 作宾语 动词不定式（短语）可以放在一些动词后面用作宾语，能以动词不定式作宾语的动词有：begin,start, want, forget, remember, show, learn, like, hate, love, ask等。例： I want to tell you a story. 我想给你讲个故事。 They begin to work at eight every morning. 他们每天早晨8点开始工作。 Don’t forget to lock the door. 别忘了锁门。 Would you like to go and have a picnic with us tomorrow? 明天和我们一起去野餐好吗？
