初二英语动词不定式用法小结

动词不定式是动词的一种特殊形式，它没有人称和数的变化，在句子中不能做谓语；它由“to+动词原形”构成，其否定形式是“notto+动词原形”.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。为使同学们更好地掌握其用法，现总结如下：

一、动词不定式作主语

动词不定式作主语，例如To think of the animals in danger is sad .为避免句子的头重脚轻，常用it作为形式主语，而真正的主语动词不定式后置，如It is sad to think of the animals in danger .常用句型:It +be+adj./n 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。应注意有些动词后面可接不定式作宾语，也可接动名词作宾语，但所表达的意义不同。常见的有：（1）stop to do sth.停下来去做另一件事；stop doing sth. .停止正在做的事（2）tryto do sth.尽力做某事；try doing sth.尝试做某事（3）remember/forget to do sth.记住／忘记去做某事；remember/forget doing sth.记得／忘记做过某事。下列动词（enjoyfinish keep mind practice spendadvise suggest allow）后面不能用不定式，用动名词作宾语

三、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，构成tell/ask/want /call/invite sb. to do sth.结构。而表示使役动词和感官动词后面的宾语补足语时应省去to，（在被动语态中应加上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)，半帮助(help)(即在动词help后面作宾语补足语时，to可有可无)”。

四、动词不定式作状语

动词不定式作状语主要用来修饰动词，表示目的they did lots of workto save the candas等。，表结果，常用结构有too + adj./adv. + to do sth. adj./adv.enough + to do sth，表原因be +形容词+ to dosth如I am surprised to hear the news.为了强调目的，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 to。

五、动词不定式作后置定语时，与被修饰的名词逻辑上有动宾关系。如果动词不定式是不及物动词时，则要带上与之搭配的介词，构成及物动词短语。动词不定式作后置定语常用于“have/has＋某事＋to do”（some words to say, nothing to do,enough place to live）“It’s time to do sth.”等结构中。

六、特殊疑问词+不定式

特殊疑问词what when why how where等可以和不定式连用在句子做各种成分。如How touse compurers is a problem. I can`t decide when to do it .

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

英语动词不定式的完成式用法小结

英语动词不定式完成式在使用语境中的学习与考查 江苏省沛县湖西中学鹿俊先221611 综观近年的英语高考试题，我们可以看到题目的设置往往强调语言知识在特定语境中的使用，把语言知识放在了语用层面上，即考察实际应用知识的能力。 英语动词不定式的完成式，即(to) have +动词的过去分词形式，是中学英语学习中的重点及难点知识之一，也是高考试题中频繁出现的形式。对于这一形式考查的题目设置通常围绕三类语境，即陈述已经发生过了的事实，推测可能已经发生过了的事实，表达与过去实际情况相反的事实。下面分别加以叙述，以便从语用角度掌握这一语言知识。 1.陈述已经发生过了的事实。 1.1.置于表示情感反应的动词、形容词、分词之后，作为引起该反应的刺激，表示情感反应之前完成的动作。例如： I'm sorry to have given you so much trouble. (=I'm sorry that I gave / have given you so much trouble.) It is good to have finished work for the day. (=I am pleased because I have finished.) She said she was sorry to have missed you. (=She said she was sorry that he had missed you.) There was a smile on the boy's face, which seemed to show that he was happy to have given his life to his country. (=…he was happy that he had given his life to his country.) 1.2.置于be said, be considered, be believed, seem, appear, happen, turn out,等之后表示这些动作之前完成的动作。例如： I don't know whether you happen to have heard, but I am going to study in the U.S.A. this September. Charles Babbage is generally considered to have invented the first computer. (=It is generally considered that Charles Babbage invented the first computer.) He is said to have studied abroad, but I don't know which country he studied in. (= It is said that he studied abroad, b ut….) I appear to have made a small mistake. (=It appears that I made / have made a small mistake.) He seems to have missed the train. (=It seems that he missed the train.) 1.3.置于should之后，表达说话人对已发生了的事实的情感的反应，如惊奇、遗憾、喜悦、不安、失望，等，should相当于汉语中的“竟然”，“居然”。例如：They were surprised (that) a child should have worked out the problem while they themselves couldn't. It is strange that she should have married such an old man. 2.推测可能已经发生过了的事实。 2.1.置于must, will, would, can't, couldn't 之后，表示很有把握的推论。例如： The city must have been prosperous, for it enjoyed a high level of civilization. An ambulance is waiting in the street. Somebody must have been hurt or killed. --I met her soon after the war.

动词不定式用法例句总结

定义 （语态）动词和参与此动作的主语之间关系的一个术语。当主语是动作的发起者（或之一）时，称为主动语 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 honour to be invited to Mary's birthday party. （不定式作主语是被动语态to be invited 是被邀请）It was impossible for lost time to be made up. （不定式作主语） I wish to be sent to work in the country. （不定式作宾语） Can you tell me which is the car to be repaired? （不定式作定语） He went to the hospital to be exam in ed. （不定式作状语） My work is to clea n the room every day. （不定式作表语） 在There be 结构中，修饰主语的不定式可用被动，也可用主动。如：There are still many things to take care of （to be taken care of）. 但有时两种形式表达的意思不同，如：There is noth ing to do now.（ We have nothi ng to do no w.） There is nothing to be done no w.（We can do nothing no w.） 形式 1）现在式：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。一般为：动词+ to do sth He seems to know this. I hope to see you aga in. = I hope that r II see you aga in. 我希望再见至M尔。 2）完成式：表示的动作发生在谓语动词表示的动作之前。 rm sorry to have give n you so much trouble. He seems to have caught a cold. 3）进行式：表示动作正在进行，与谓语动词表示的动作同时发生。 He seems to be eat ing someth ing. 4）完成进行式： She is known to have been wreaking on the problem for many years. 一般在表示情绪的动词后加to do也表将来 疑问词 疑问词who,what,which,when,where,whether,how 语等。如： ①W hen to leave for London has not bee n decided yet. ② Mr. Smith did n't know whether to leave or stay there. ③ I asked Professor Xu how to lear n En glish well. ④The questi on was where to get the medici ne n eeded. 以上例句中疑问词+不定式部分，均可转换为相应的 could lear n ......... 后可接不定式构成不定式短语，在句中作主语、宾语、表 （不定式在句子中做主语） （不定式在句子中做宾语） （不定式在句子中做直接宾语） （不定式在句子中表语） 从句形式。如：①When we shall leave …③? -how I

八年级英语语法专题（II）动词不定式的用法 初中英语单位测试,中考英语语法辞汇,中考英语应试技巧,中考英语模拟题,更多精美内容尽在“尹氏欢愉英语”中，欢迎大家登岸学习。 动词不定式是初中英语的语法重点之一，也是每年中考英语试题的考点之一。它是动词的一种非谓语情势，没有人称和数的变化，不能单独作句子的谓语。其构成情势为＂to+动词原形＂，to为动词不定式的符号，本身无意义。动词不定式具有两大特点：1.具有动词的特点，是以，后面可以跟表语、宾语或状语，构成动词不定式短语。2.具出名词、形容词或副词的特点，可以在句子中用作主语、宾语、宾语补足语、状语、定语、表语及同位语等。根据新课标八年级要求介绍近几年全国部分省市的中考英语试题为例，对不定式的难点以及它在中考英语中的考查点，作一简要的总结八年级英语下册总结和分析，供同学们学习时参考。 一、动词不定式作主语 1. It's our duty _________ the room every day. A. to clean B. cleaned C. clean D. cleans(甘肃省) 2. It's hard for us _________ English well. A. learn B. learns C. to learn D. learning(江西省) 3.建造这座立交桥将花费工人们一年多的时间。 It will _________ the workers over a year _________ _________ the flyover.(BeiJing市海淀区) 4. It's very nice _________ you to get me two tickets _________ the World Cup. A. for，of B. of，for C. to，for D. of，to(安徽省) Keys：1. A 2. C 3. take，to，build 4. B ［简析］动词不定式作主语时，可以直接放在谓语动词前面的主语位置，也可以用先行词it作情势主语，而将真正的主语(不定式)置于后面。常见的句式有： (1)It is +形容词(of sb)to do sth. ⑵It is +名词(for sb)to do sth .⑶It takes sb some time to do sth .⑷It is +形容词(for sb)to do sth.句式 (1)中常用nice，kind，clever，good，right，wrong，foolish，careless等形容词，与前置词of搭配，这些形容词常表述不定式逻辑主语的属性或性质；句式⑷中常用hard，difficult，easy，important等形容词，与前置词for搭配，暗示不定式暗示的动作、举动的性质。 注意：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)To see is to believe. 百闻不比一见。(错)It is to believe to see. It's for sb.和It's of sb. 1) for sb.常用于暗示物质的特征特点，暗示客观情势的形容词，如easy, hard, difficult, interesting, impossible 等： It's very hard for him to study two languages.对他来讲学两门外语是很难的。 2) of sb的句型一般用暗示人物的性格，道德，暗示主观感情或态度的形容词，如good, kind, nice, clever, foolish, right。 It's very nice of you to help me.你来帮助我，你真是八年级下册英语语法太好了。 for与of的辨别要领：用前置词后面的代词作主语，用前置词前边的形容词作表语，造个句子。如果道理上通顺用of，欠亨则用for。如：You are nice.

动词不定式 一. 定义： 动词不定式是非谓语动词的一种，它没有人称和数的变化，在句子中不能独立作谓语，但它仍保持动词的特点，既可以有自己的宾语和状语。同时动词不定式又具有名词、形容词、副词的特征，在句中可以作主语、表语、宾语、宾语补足语、定语和状语。 二. 动词不定式的构成：to+动词原形 三. 动词不定式作宾语 动词不定式作宾语的注意事项（6点） 1.可以接带to的动词不定式作宾语的动词主要有：要求选择同意(ask, choose, agree)，期望决定学习(expect, hope, decide, learn)，宁可假装知道(prefer, pretend, know)，希望想要愿意(wish, want, would like / love)。如： 1)We decided to talk to some students about why they go there. 2)He prefers to eat white bread and rice. 3)Id love to visit Mexico. 2.动词decide, know, learn, show, teach, tell...，介词结构on...可用疑问词带to 的不定式短语作宾语，但why后面的不定式不带to。如： 1)Could you please tell me where to park my car? 2)It gives advice on what to do in lots of different situations. 3.动词feel, find, make, think等后面，可以用it作形式宾语代替真正的宾语——动词不定式，句子结构是...feel / find / make / ... it + adj. / n. + to do...。如： I find it difficult to remember everything. 4.既可接动词不定式又可接v_ing形式作宾语，意思差别不太大的动词有begin, start, like, love等。一般说来，动词不定式表一次、数次的具体动作、将来动作或动作的全过程，v_ing形式表习惯性的连续动作。但是这种区别并不很严格，特别是美国英语，即使是习惯性的动作也可以用动词不定式。如： 1) Then I started to watch Tv. 2) I am beginning to understand my parents. begin用了进行时态，后面只接不定式作宾语，表示事情刚开始，还要继续下去。 3) I like to eat vegetables. 感知动词like, love, know等一般不用进行时态。 5.后接动词不定式或v_ing形式作宾语，意思差别较大的动词有forget, remember等。后接不定式作宾语，表动作尚未发生；后接v_ing形式作宾语，表动作已经发生。stop to do 停下来做另外一件事，to do是目的状语；stop doing停止做、不做当前这件事，doing是宾语。try to do尽力做，try doing试试看；go on to do接着做另外的事，go on doing 继续做原来的事。如： 1)When I left home, I forgot to bring it with me. 2)I stopped using them last year. 6. 不定式作宾语时，如带有宾语补足语，则要把不定式放到后面，用it作形式宾语，构成“主语+动词+it+宾补（形容词、名词）+不定式”结构。 如：He found it very difficult to get to sleep. 他发现很难入睡。 ( ) 1. I often see Tom____on the playground. When I passed the playground yesterday, I saw him_____. A. play; playing B. to play; play C. playing; to play C. playing; play
