初中动词不定式专题讲解及练习(全面)

语法：动词不定式

动词不定动式是一种非谓语动词形式，它没有人称和数的变化，在句子中不能作谓语，但可以作除谓语之外的其它任何句子成分（主语、表语、宾语、宾语补足语、定语和状语）；动词不定式具有名词、形容词和副词的特征，同时还保持动词的某些特点，既可以有自己的宾语和状语，动词不定式和它的宾语和状语构成不定式短语。

一、构成：to do .否定式not to do

二、常见时态：一般时to do 进行时to be doing 完成式to have done

完成进行式to have been doing

三、动词不定式在句子中的成分

1、作句子的主语：现实中常用it作形式主语，而把真正的主语动词不定式（或短语）

后置。

比较下列句子

To learn from your friends is important.=It is important to learn from your friends .

To leave without saying goodbye is impolite.= It is impolite to leave without saying goodbye.

To chat with Miss White is a pleasant thing.=It is a pleasant thing to chat with Miss White.

To walk to school takes me ten minutes.=It takes me ten minutes to walk to school.

句型总结

●It is + adj. + of sb. to do…= sb. is\are +adj. +to do…在以某些表示人的品质、特征等的形容词（如kind、good、nice、wrong、clever、right等）作表语时，不定式之前常加一个引起的短语，说明不定式指的是谁的情况（可以理解为某人的好，坏，聪明，愚蠢，对，错等等）。

It is very kind of you to help me.

It’s not polite of him to speak to old people like that.

●It is + adj. + for sb. to do…≠ sb. is\are +adj. +to do…如果要说明不定式表示的动作是谁做的，则在不定式前加一个for引起的短语，即不定式的逻辑主语。

It is necessary for us to study hard.

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？

动词不定式练习题及 讲解

动词不定式用法要点讲解 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 a quarter of an hour. ④It＋be＋形容词＋of sb＋to do It is stupid of you to write down everything the teacher says. ⑤It seems(appears)＋形容词＋to do It seemed impossible to save money. 二、作宾语 ⒈不定式作宾语 ①以下动词后，只能跟不定式作宾语。如： agree,ask,aim,arrange,choose,decide,demand,expect,fail ,help,hope,lean,long manage,offer,plan,prepare,pretend,promise,refuse,wish等，这些词大部分可接 th at引导的从句。如： When our visit to the farm was over, we expected to start back on foot. When our visit to the farm was over, we expected that we would start back on foot. ②当复合宾语中的宾语是不定式时，先用形式宾语it代替不定式，把不定式置于补语之后，即：主语＋动词＋it＋补语＋to do句式。 He feels it his duty to help the poor. ③介词but,except,besides+to do(do) 在这种句型中，如介词前有动词do，后面应接不带to的不定式；如无do，则接to 不定式，即带do不带to，带to不带do。如： The enemy soldiers had no choice but to give in. ⒉部分动词后面，既可接动词不定式，也可接动名词作宾语，意义不变。如：begin,continue,start,hate,like,love,need,require,want等。 在need,require,want后接-ing形式，表示被动意义，也可接不定式，但要用被动形式，如：Your handwriting needs improving(tobe improved). hate,love,like接不定式表示特定的未来事件，接动名词表示目前正在进行的活动或一般的行为。 在下列情况下，一般要用不定式： ①hate,like,love前有would(should)时，如：I'd like to have a cup of coffee. ②当谓语动词begin,continue,start等是进行式时，如：Thestudents are starting to work on the difficult maths problem. ③begin,continue,start与know,understand等状态动词连用时，如：I soon began to understand what was happening. 3．advise,allow,encourage,forbid,permit等动词后接动名词作宾语，或带不定式作宾语补足语。如： Our teachers don't permit our/us swimming in the lake. Our teachers don't permit us to swim in the lake. 4．部分动词后接不定式或动名词时，意义差别较大，应根据句子语境选择使用。 ①forget,remember,regret后接不定式，表示现在或未来的动作，接动名词表示动作已经发生。如： We regret to tell you that all of you are not invited to attend the meeting. They regretted ordering these books from abroad. ②mean to do 打算做某事 ;mean doing 意味着…… ③try to do 设法尽力做某事; try doing 试着做某事 ④stop to do 停下一件事去做另一件事（不定式作目的状语）; stop doing 停止做某事 ⑤can't help doing 禁不住…; can’t to do不能帮助干…… ⑥go on to do 做不同的事或不同内容的事; doing 继续不停地做某事，指同一动作的继续 ⑦leave off to do 离开某地去干什么（目的状语）; leave doing停下某事 三、做表语 To be kind to the enemy is to be cruel to the people. 四、作定语 不定式在句中作定语，置于被修饰的名词或代词之后。如： Have you anything to be taken to your sister? 收集于网络，如有侵权请联系管理员删除
