inconvenient, unnecessary, right, wrong...)＋( for/of sb.)＋ 不定式 【例如】 It is essential to reserve a table in advance of Christmas Eve. hard to put my hopessintoswords.

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
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？

动词不定式讲解、专项练习及答案
初中英语语法（动词不定式） 1．不定式的基本形式与结构 动词不定式指通常由to加上动词原形(如to write) 所构成的一种非限定性动 词形式，但在有些情况下to可以省略。动词不定式有进行体和完成体(如上to be writing，to have written)，也有被动态(如to be written)，所有的主动词，不论是 及物动词还是不及物动词，也不论是动作动词还是状态动词，都有不定式形式。 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，
非谓语动词之动词不定式(todo)的用法
非谓语动词之动词不定式（to do）的用法 非谓语动词是指在句子中不是谓语的动词，主要形式有：不定式、动名词和分词（现在分词和过去分词）。 “to do”动词不定式的变形 动词不定式的用法 充当主语（一般会用it 当形式主语） To swim here is dangerous. = It is dangerous to swim here. To pass this English exam is unlikely. = 充当表语（多数情况下，可以转换成动词不定式做主语） My job is to help with your English learning.

充当宾语补足语 I persuaded him to make a speech in public. 注意：在感官动词／使役动词／help后（see, hear, watch, notice, make, have, let后不定式做宾补时，可省略“to”） I saw them have a disagreement on who should sweep the floor. （我看到了他们争论的整个过程） 但，感官动词后面也可接Ving形式，表示正在进行。 I saw them arguing about who should sweep the floor. （我看到他们正在争论谁该扫地，并不一定看到了整个过程） 充当状语（目的，原因，结果状语，其逻辑主语与句子主语一致） I wrote him a letter to further explain this matter. （目的状语） I’m sorry to bother you.（原因状语） He queued for hours at the box office only to find that the show was sold out. （结果状语，only + to find/realize/discover表示出乎意料的结果） 充当定语（不定式作定语，要放在所修饰的词的后面） I have a lot of dishes to wash. Do you have anything to say There are 3 questions to answer. 一些固定句型中不定式省略“to” had better would rather do… than do… why not do “except/but” 有“do” 无“to”，有”to”无“do” have nothing to do but do… do everything but/except have no choice but to want nothing but/except to 当两个或多个作用相同的不定式并列（and/or/than）时，通常只保留第一个不定式的“to”.

动词不定式讲解
动词不定式的用法 概念： 动词不定式由to+动词原形构成。这里的to是不定式标志，没有词义。不定式具有名词、形容词或副词的某些语法功能，又有动词的时态和语态的特点及作用。可以做主语、宾语、宾语补足语、表语、定语、状语。 一、作主语 动词不定式作主语时，句子的谓语动词常用单数，其位置有以下两种： (1)把不定式置于句首。如： To get there by bike will take us half an hour. (2)用it作形式主语，把真正的主语不定式置于句后，常用于下列句式中。如： ①It＋be＋名词＋to do It's our duty to take good care of the old. ②It takes sb+some time+to do How long did it take you to finish the work ③It＋be＋形容词＋for sb＋to do It is difficult for us to finish writing the composition in a quarter of an hour. 在句型③中，常用表示客观情况的形容词，如： easy, difficult, hard, important, possible, impossible, comfortable, necessary, better; the first, the next, the last, the best, too much, too little, not enough ④It＋be＋形容词＋of sb＋to do It is stupid of you to write down everything the teacher says. 在句型④中，常用 careless,clever,good,foolish,honest,kind,lazy,nice,right,silly,stupid,wise rude, clever, foolish, thoughtful, thoughtless（欠考虑的；不考虑的）, brave, considerate(考虑周到的), selfish(自私的)等表示赞扬或批评的词。在不定式前的sb，可看作其逻辑主语。这一句式有时相当于Sb is＋形容词＋to do句式，如：It's kind of you to help me with my English.=You are kind to help me with my English. ⑤It seems(appears)＋形容词＋to do It seemed impossible to save money. It seemed selfish of him not to give them anything. 他不给他们任何东西，这显得太自私了。 注意：1) 其他系动词如，look，appear等也可用于此句型 2) 不定式作为句子主语时，动词用单数形式。 3) 当不定式作主语的句子中又有一个不定式作表语时，不能用It is… to…的句 型 对应性：To see is to believe. 百闻不如一见。 二、作宾语 1) 以下动词后，只能跟不定式作宾语 afford （付得起），agree（同意），aim(力求做到), appear（显得），arrange（安排），ask（要求），attempt （试图），care（想要），choose（决定），claim（声称），condescend （屈尊），consent（准许），decide（决定），demand（要求），determine（决心），endeavor （竭力），expect（期待），fail（未履行），help（帮助），hesitate（犹豫），hope（希望），learn（学会），manage（设法），neglect（疏忽），offer（主动提出），plan（计划），prepare （准备），pretend（假装），proceed（接着做），promise（答应），prove（证明），refuse （拒绝），resolve（解决），seem（觉得好像），swear（发誓），tend（往往会），threaten （威胁），undertake（承诺），volunteer（自愿做），vow（发誓），want（想要），wish（希
(完整版)动词不定式的用法总结
动词不定式的用法总结 动词不定式在中学英语中应用非常广泛，一方面在句中可起名词、形容词或副词的作用，同时也可在句中作主语、宾语、定语、状语和宾语补足语。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。 现就以下几方面介绍如下。 一、不定式结构 1. 带to的不定式结构 能直接跟带to的不定式结构的动词主要有：want, ask, tell, hope, learn, try, decide, forget, remember, like, love, stop, go, come等。 如： I want to go to the movies with you. 我想跟你一起去看电影。 Don’t forget to turn off the light before you leave. 在你离开之前别忘了关灯。 注意：动词不定式的否定形式是在不定式前直接加not，即not to do sth.。
如： Dave told me not to wake up Kate. 大卫告诉我别叫醒凯特。 2. 不带to的不定式结构 以下几种情况使用不带to的动词不定式： (1)在固定词组had better之后。 注意：had better的否定形式是had better not do sth.。 如： You had better go home now. 你最好现在回家。 It’s cold outside. You’d better not go out. 外面很冷，你最好不要出去。 (2)在let, make, see, feel, watch, hear等感官或使役动词后，要跟不带to的动词不定式作宾语补足语。 如： I made them give me the money back. 我迫使他们把钱还给我。 I didn’t see you come in. 我没看见你进来。 (3)在引导疑问句的why not之后。 Why not+不带to的不定式是Why don’t you do的省
