动词不定式专题一
动词不定式是一种非谓语动词，其结构为“(to) + 动词原形”。
动词不定式的用法I:
1. 用作主语
to不定式常用作句子主语，但多数情况下常用it作形式主语，将to不定式后置。
例如：To take part in sports and recreation is important.
It is important to take part in sports and recreation. 参加运动和娱乐很重要。
在动词不定式用作主语的句子中常出现一个for引起的短语，用来说明不定式的逻辑主语。
例如：To fly was difficult for human beings.
It was difficult for human beings to fly. 人类飞行曾经是很困难的。
To learn to speak Chinese is not easy for a foreigner.
It is not easy for a foreigner to learn to speak Chinese. 外国人学说中国话不容易。
而在某些形容词如kind，good，nice，clever，careless，stupid等作表语时，不定式前常加上一个of引起的短语，说明不定式指的是谁的情况。
例如：It’s kind of you to say so. (=You are kind to say so.) 你这样说太好了。
It’s careless of you to give me the wrong number. 你很粗心，给了我错的电话号码。
It was stupid of him to buy such a thing. 他很笨，买这样的东西。
to不定式还可以用于结构“it + take + (sb) + 时间段+ to不定式”，解释为“（某人）花时间做某事。
例如：It usually takes me half an hour to ride to my office. 我通常花半小时驾车到我办公室。
It will take three days for the parcel to reach Beijing. 这个包裹将要花三天寄到北京。
2. 用作表语
to不定式可用于be动词后做表语。
例如：Qu Yuan’s job was to give advice to the king. 屈原的工作是向皇帝进谏。
My wish is to become a college student. 我的愿望是成为一名大学生。
His plan is to set up another book store in the street. 他的计划是在街上再办一家书店。
3. 用作动词宾语
不定式常用作某些动词的宾语如hope，wish，agree，learn，like，love，manage(设法)，offer(表示要)，plan，promise，remember，forget，try(努力)，decide(决定)，want，begin，start等。
例如：She wanted to buy a few postcards. 她想买几张明信片。
The car repairer began to check my car engine. 汽车修理工开始检查我的汽车发动机。
It started to snow at midnight. 半夜里开始下雪了。
在某些动词如know，learn，decide，wonder(想知道)，remember，forget，tell，show，teach等后，还可以接“疑问词+ to不定式”。
例如：I didn’t know what to say to him. 我不知道对他说什么好。
They are learning how to use the computer. 他们正在学习怎样使用电脑。
Did they tell you where to go? 他们告诉你去哪儿吗？
The farmer showed us how to cut rice. 农民教我们怎样割稻。
★动词不定式作宾语与动名词作宾语辨析
⑴在动词want，wish，hope，decide，help，promise，plan，manage，agree等后只能用动词不定式作宾语，而在动词dislike，keep，finish，mind(介意)，practise(练习)，enjoy等后只能用动名词作宾语。
例如：We promise to keep our classroom clean all the time. 我们答应始终保持我们
的教室清洁。
Ted enjoys growing flowers. 泰德喜欢种花。
Would you mind telling me your address? 你介意把你的地址告诉我吗？
They have all finished reading the passage. 他们都读完了这篇短文。
⑵在like，love，prefer后既能跟动词不定式作宾语也能跟动名词作宾语，但意思上有细微差别，不定式多表示具体的动作，而动名词多指一般的情况，表泛指。
例如：He would like to listen to pop music for a while. 他想听一会儿流行音乐。
He likes listening to pop music. 他喜欢听流行音乐。
She should love to invite her friends to her house next Sunday. 她想邀请她
的朋友下个星期天到她家来。
She loves inviting her friends to her house on Sundays. 他喜欢在星期天邀
请她的朋友到她家来。
⑶在begin，start，continue(继续)后接既能跟动词不定式作宾语也能跟动名词作宾语，且意义没有差别。
例如：We began to learn / learning English two years ago. 我们两年前开始学习英
语。
Le t’s continue to play / playing the PC game. 咱们继续玩电脑游戏吧。
⑷remember，forget，mean，go on，stop，try后既能跟动词不定式也能跟动名词但意义差别很大。
①remember to do sth. 记得要做某事
remember doing sth. 记得做过某事
例如：Remember to tell him not to smoke any more. 记得叫他不要再抽烟了。
I remember smoking the first cigarette. 我还记得第一次抽烟的情景。
②forget to do sth. 忘记要做某事
forget doing sth. 忘记做过某事
例如：He forgot to telephone Mike. 他忘了给麦克打电话。
He forgot telephoning Mike this morning. 他忘了今天早晨曾给麦克打过
电话了。
③mean to do sth. 打算做某事
mean doing sth. 意味着......、意思是......
例如：I meant to go jogging this morning. 我今天早上本打算去慢跑的。
Wasting time means killing life. 浪费时间就意味着浪费生命。
④go on to do sth. 继续做另外一件事情（强调事情的转接）
go on doing sth. 继续做未做完的事（强调动作的待续）
例如：Let the children go on telling stories one by one. 让孩子们继续一个一个地
讲故事。
After the jazz, the band went on to play a piece of country music. 在爵士
乐之后，乐队接着弹奏了一曲乡村音乐
⑤stop to do sth. 停下来做另一件事
stop doing sth. 停止做某事
例如：They stopped to have a look. 他们停下来看一看。
They stopped looking out of the windows. 他们不再看窗外了。

(完整)初中英语be动词用法

It is a dog. 它是一只狗。 This is a bike .这是一辆自行车。 That is a cup . 那是一个杯子。 is也可与主语缩写, 如:He is=He's,My mother is=My mother's等。但是This is不可缩写。而is与not可缩写成isn't。 如:This isn't a book.这不是一本书。 [解题过程] 根据以上叙述我们可以把动词的用法以口诀的形式表述出来： 我（I）是am, 你（you）是are, 剩下is留给她（she）,他（he）,它（it）, 两个以上都用are。 be动词用法歌 be动词真伟大，生出is, am, are。 我用am，你用are，is连接他，她，它。 单数名词用is，复数名词全用are。 变疑问，往前提，句末问号莫丢弃。 变否定，更容易，be后not莫忘记。 疑问否定任你变，句首大写莫迟疑。 1 用动词be （am，are，is）填空
动词不定式的用法学案
动词不定式的用法 非谓语动词是指那些在句中不能单独充当谓语的动词，可分为不定式，动名词，现在分词和过去分词。 1. 不定式形式:由to＋动词原形构成。 2.用途： 在句中不能作谓语。它具有动词的性质，本身可以带宾语和状语。动词不定式在句中除了不做谓语，可以作句子任何成分。动词不定式的被动形式除了一般形式外还有其完成式和进行式。 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，这一动作一定由施动者发出。动作的施动者我们称之为不定式的逻辑主语，其形式如下： 主动形式被动形式 一般式（not） to make （not） to be made 完成式（not） to have made （not） to have been made 进行式（not） to be making (1)语态 如果动词不定式的逻辑主语是这个不定式所表示的动作的承受者，不定式一般要用被动语态形式。如： It's a great honor _____________ (invite) to Mary's birthday party.（不定式作______） I wish ______________ (send)to work in the country.（不定式作__________） Can you tell me which is the car________________( repair)（不定式作________） He went to the hospital______________________ (examine).（不定式作__________） (2)时态 1) 现在时：一般现在时表示的动词，有时与谓语动词表示的动作同时发生，有时发生在谓语动词的动作之后。 I hope_________(see) you again. = I hope that I'll see you again. 我希望再见到你。 2) 完成时：表示的动作发生在谓语动词表示的动作之前。 I'm sorry __________________ (give) you so much trouble. 3) 进行时：表示动作正在进行，与谓语动词表示的动作同时发生。 He seems ____________________ (eat) something. 4) 疑问词who, what, which, when, where, whether, how后可接不定式构成不定式短语，在句中作主语、宾语、表语等。如： Eg. 什么时候出发去伦敦到现在还没有决定呢。 _______________________________________________________________________我问陈老师怎么样学好英语。 __________________________________________________________________________

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
动词不定式的精讲与专项练习
动词不定式（The Infinitive） 一、概述 不定式是动词的一种非谓语形式，在句中不能单独作谓语。它有两种形式：（1）带to的不定式；（2）不带to的不定式（即通常所说的动词原形），它可以和助动词或情态动词构成谓语。不定式既有动词性质，又有名词性质。 1）不等式具有动词性质，即它有时态和语态的变化；可有自己的宾语或状语并构成不等式短语。如： Would you like to tell me an interesting story? 你可不可以给我讲一个有趣的故事？（不等式to tell有自己的宾语me和story）He was too clever a man to be fooled.他这个人很机灵，不会被愚弄的。（不等式的被动语态） I’m going to go there by bike. 我想骑自行车去那儿。（不定式有状语there） They will set up more primary schools in the countryside. 他们将在乡村修建更多的小学。（不带to的不等式与助动词will一起构成谓语）但是，不等式没有人称和数的变化，即不受人称和单数、复数的限定或影响。 She likes to play the accordion. 她喜欢弹奏手风琴。 She liked to play the accordion when she was young. 她很小就喜欢弹奏手风琴。 2）不等式具有名词性质，即它在句中可用作主语、宾语、表语等。如： To see is to believe. 百闻不如一见。（作主语） This suit doesn’t seem to fit me.这件衣服似乎不适合我穿。（作表语） She wanted to see which shops offered the best service. 她想看看哪家商店提供最好的服务。（作宾语） There’s no need to be worried. 不需要担心。（作定语） He went there to see what would happen.他去那儿是想看看会出什么事。（作状语） 3）不等式虽然在语法上不能有主语，但它表示的动作，在意思上是可以有自己的主语，在语法上这个主语称为不等式的逻辑主语。这个逻辑主语可能是整个句子的主语、宾语等，也可以用一个由for引起的短语表示。如： His friends tried to encourage him. 他的朋友设法鼓励他。（不等式的逻辑主语His friends同时也是句子的主语） Every year, tobacco companies must persuade new people to start smoking cigarettes. 每年烟草公司要设法使一些比吸烟的人开始吸烟。（不等式的逻辑主语new people是句子的宾语）It’s very difficult for a foreigner to learn Chines e. 外国人学汉语是很不容易的。（不等式的逻辑主语由for引起的短语表示） 另外，不等式的否定形式一般在它的前面直接加not或never。 The teacher has told me many times not to come late again.老师多次告诉我不要再来晚了。 She seems not to have a bright time with her new friends.和新朋友在一起她似乎过得不是太好。 二、不定式的主要用法 动词不等式具有名词、形容词及副词的特征，因此在句中可作主语、宾语、宾语（或主语）补足语、表语、定语、及状语等。 1、不定式作主语 ①不等式作主语时，谓语动词用单数形式。 To conquer English is not easy. 征服英语不容易。 To make plan firs t is a good idea. 先制定计划是个好主意。 To know everything is to know nothing. 事事皆通，无一精通。 ②不等式作主语时，常常用形式主语it替代，而将真正的主语不等式放在句子的后面。 It is necessary to master a foreign language.掌握一门外语很有必要。 It’s a great pleasure to see you again.再次见到你真高兴。 It is a bad manner to stare at a foreign guest.盯着外宾看是一种不良的举动。 ③如果说明不等式表示的动作是谁做的，可以在不等式的前面加一个for引起的短语，这就是常见的“It is adj./n. for sb. to do sth.”句式。如： It is good manners for an Arab to stand close to his friends when they are talking. 对阿拉伯人来说，交谈时站得离朋友近些是好的礼貌。 It is a great honor for us to be presented at the party.我们能来参加晚会，深感荣幸。 It will be a regret for us not to help him. 我们没有帮助他是个遗憾。 ④在某些形容词（如kind, good, nice, wise, unwise, clever, silly, wrong, right, foolish, stupid, careless, considerate, rude, naughty, impolite等）作表语时，不等式前常加一个以of引起的短语，来说明不等式指的是谁的情况。这就是常见的 “It is adj. of sb to do sth.”句式。如：

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）
