---------------------------------------------------------------------------- 动词不定式可以有自己的逻辑主语,即不定式动作的发出者通常用for + 名词(代词)或of + 名词(代词)放在不定式的前面。

It’s difficult

It’s kind of you

It’s silly of him

他做那件事真是太傻了。

注:确定逻辑主语前是加of还是加for的办法是:如果表语可以修饰逻辑主语,即能说明逻辑主语性质和特点,就加of引出逻辑主语否则用for。

Tom is difficulty.

汤姆是困难的。

You are kind.

以上句中的necessary和difficult不能修饰flight attendant和Tom,所以用for +名词(代词)做逻辑主语,而→↓两句中的kind和silly可以修饰人,用of +名词(代词)。

高中英语讲解不定式语法

高中英语语法讲解不定式 (The Infinitive) 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。 E.g. He want his students to read the book aloud. A. 1不定式的构成(以动词do为例) 2 不定式的意义 不定式的一般式(to do ) 一般式表示的动作或状态,发生在谓语动词表示的动作或状态的同时或之后My wish is to become a doctor He seemed to be tired. She stopped to have a rest. 不定式的被动式 (to be done) 当不定式的逻辑主语是这个不定式所表示的动作的承受者时,不定式一般要用被动式. The building to be finished next month is for our teachers. I am going to Beijing, I have something to take to my parents, do you have something to be taken to your parents? 如果谓语表示的动作(情况)发生时, 不定式表示动作正在进行,这时候不定式就要用进行式.(to be doing) They are said to be building another bridge across the street. They seemed to be talking about something important. When I went to his home, he happened to be traveling around the world. I’m glad to be working with you. 如果不定式所表示的动作或状态发生在谓语动词所表示动作或状态之前,就用完成式 (to have done) ;若是在此基础上的被动含义,就用完成被动式( to have been done). He is said to have written a novel about the Long March. He thought it a pity not to have invited us. The assistant seemed to have been fired. He is said to have been taught French when he was a child. Einstein is said to have built up his theory when he was in his twenties. 如果不定式的动作是在谓语所表示的时间之前一直在进行的动作,就要用完成进行式. They are said to have been collecting folk song in Xinjiang. We’re happy to have been working with the experts all the month.

初中英语语法精讲动词不定式用法(教案)

动词不定式用法 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。 下面以动词不定式在句中的作用来予以详细说明。 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. 点击规律:动词不定式在句中作主语时,常放在It is +adj +(for sb.)+(not)to do sth句型中,表示说话人对客观事件的决断,意为:做…..是……的,it仅作形式主语,真正的主语是to do sth It is very interesting to read.读书是有趣的 It is useful to read.看书是有用的 It is healthy to run every day.每天跑步是健康的 It is a little difficulty for me to work out this question.解出这道题对我来说有点难 It is bad not to finish homework.不完成作业是糟糕的 It is bad to be late for school.迟到是糟糕的 It is+adj+of sb +(not)to do sth该句型通常表示说话人对客观事件的惊讶、兴奋、懊悔、难过等感叹情绪,与It is +adj +(for sb.)+(not)to do sth的意义不同。 It is very kind of you to tell me the truth.你能告诉我事实,真是太好了 It is stupid of him to do such a silly thing.他做那件傻事,真是太笨了 It is very clever of you to work out this question. 你能解出这道题目,真是太聪明了 It is very wise of you to read this novel. 你看这本小说,真是太明智了 这个句型中用介词of而不是for的原因是这里的形容词是用来形容人的品质性格的。 类似的词有:careless,careful,clever,considerate,foolish,good,impolite,kind,naughty,nice,silly,stupid,friendly 因此区分是用It is +adj +(for sb.)+(not)to do sth还是It is+adj+of sb +(not)to do sth,要

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

不带to的动词不定式讲课教案

不带to的动词不定式有哪些 不定式是英语动词的非限定形式之一,是英语中一种非常活跃的语言现象,不带to的不定式(bare infinitive)是我们学习、掌握和运用这一语法现象的难点。本文的目的就是要对不带to的不定式作一粗浅的探讨。首先要指出的是,不带to的不定式的使用实际上非常普遍,主要用在情态动词和助动词will,shall,would,should,can,could,may,might,must…以及在作为情态动词的need和dare之后。但因为这一点在学习英语的过程中极易掌握,故不在此赘述。除此以外,在下列情况下也要使用不带to的动词不定式。 1.在see,feel,hear,watch,observe,listen to,look at, notice等感官动词或短语以及let,have,make等表示祈使意义的动词后面;不定式作宾语补足语不能带to;help后面的不定式可以不带to,也可以保留to;know在一定的条件下,后面的不定式作宾语补足语时可以不带to。例如: I saw the man come out of the house. I heard her say that she was from Japan. We felt the house shake. They watched the sun sink into the sea. Did you notice him stop? They did not observe Jim come in and go upstairs. She was listening to him climb the stairs. Look at the boy run! I'll let you know as soon as I hear from her. I had him mend my watch. Electricity makes motors run. He helped me(to)plant trees. I have never known him sing so beautifully. 不带to的动词不定式跟在上述动词后面时,情况比较复杂,有以下几个问题须特别注意: (1)当上述句子变成被动语态时,原来作宾语补足语的不定式则相应地成为主语补足语。这时,不定式就一定要带to,以上述句子为例:

北京四中 撰稿老师:黄浩编审老师:蔡正礼责任编辑:丁华 动词不定式的用法讲解及练习题 不定式既具有动词的一些特征,又具有名词,形容词和副词的句法功能 否定式:not +不定式 不定式的时态 一般说来,不定式一般式表示的动作有时与限定动词表示的动作同时发生,也有时发生在限定动词表示的动作之后。如: Who heard him say that? He seems to know this. I hope to see you again. 不定式进行式表示动作正在进行,通常与限定动词表示的动作同时发生,如: They are said to be building another bridge across the river. I happened to be going that way too. 不定式完成式表示的动作发生在限定动词表示的动作之前,如: I am sorry to have given you so much trouble. I am glad to have seen your mother. 不定式的句法功能: (1)作主语 To talk with him is a great pleasure. 不定式短语作主语时,为了保持句子的平衡,往往以it作形式主语,而把不定式短语置于谓语动词之后,如: It's nice to hear your voice. (2)作表语

Her wish is to become an artist. (3)作宾语 常用于及物动词: want , hope, wish, like, need, hate, offer, prefer, begin, start, attempt, decide, determine, expect, promise, pretend, refuse ,afford, manage, help等之后,如: You should continue to learn as long as you live. 注1:如果作宾语的不定式又有自己的补语,则须用先行词it 作形式宾语,而将真正的宾语不定式后置,如: They found it impossible to get everything ready in time. 注2:不定式一般不能作介词的宾语,只有在极少数介词如:but, except等后边才行。此时不定式可以带to或不带to,如: In very cold winter weather a cold-blooded animal has no choice but to lie down and sleep. There was nothing left to do but clean the windows.(前边有do, to 省略) 但“疑问词+不定式”结构可以作介词的宾语,如: I have no idea about what to do next. (4)作宾语补足语 通常用于及物动词或动词短语:want ,wish, ask, order, beg, tell, permit, know, help, advise, persuade, allow, prepare, cause, force, require, call on, wait for 等之后,如: The teacher asked the students to hand in their homework. (5)作定语 不定式作定语时,须放在被它修饰的名词或代词之后。被修饰的名词或代词往往是不定式的逻辑宾语。 I have a lot of work to do. 当作定语的不定式所修饰的名词或代词是不定式动作的承受者时,不定式既可用主动语态,又可用被动语态,但其含义有所不同。所以如果修饰名词的不定式的动作是主语作的, 不定式用主动。

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说课讲解

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.

初中英语动词不定式讲解试题和答案

初中英语动词不定式讲解试题和答案 一、作主语,可以用it代替,it叫形式主语,动词不定式放在后面叫真正主语 1.To learn a foreign language is not easy. It is not easy to learn a foreign language. 2. It’s dangerous to drive very fast. 二、作表语 My idea is to ring him up at once. 我的想法是马上给他打电话。 如果主语部分含实义动词do,且作表语的动词又是“do”的内容,这时表语不定式的“to”可以省略。如:All I did was wait here. 我能做的就是在这里等。 三、常可接动词不定式作宾语的动词有:agree(同意), hope(希望), decide(决定), need(需要), mean(打算), wish(希望), fail(失败), want(想要), begin(开始), would like(想要)等。 He has decided to go to the countryside. 他已决心去乡下。 四、“疑问词+ 动词不定式”结构可以作动词know、think、find out等的宾语。 I don’t know who to ask. 我真不知道该问谁。 五、“疑问词+ 动词不定式”可以作动词show、teach、ask等后面的直接宾语。 She told me where to find the earphone. 她告诉我什么地方可以找到耳机。 六、如果宾语太长,可用it作形式宾语,构成“主语+ 谓语+ it + 宾语不足语(名词或形容词) + to do sth”结构,谓语动词常为find、think、feel等。 I found it difficult to stop him. 我发现拦截他很困难。 七、动词不定式可以作介词的宾语。 Autumn harvest is about to start. 秋收即将开始。 I’m worrying about what to do next.我正愁下一步该怎么办。 八、作定语的动词不定式与被修饰词有动宾关系。

详解动词不定式的五种

详解动词不定式的五种“式” 不定式根据其发生的时间不同以及所处的状语的不同,可以有一般式、完成式、进行式、完成进行式,同时根据它与逻辑主语的关系的不同,可以有主动式和被动式。如下表: 一、不定式一般式的用法 1. 表示未发生的动作 即表示发生在谓语动作之后的动作。如: I expect him to arrive tomorrow. 我预计他明天到达。 I hope to catch an early train. 我希望赶上早班火车。 The doctor advised me to take a complete rest. 医生建议我完全休息。 2. 表示同时发生的动作 即表示与谓语动作同时发生或略先于谓语动作的动作。如: Who heard him say that? 是谁听到他这样说的?(say与heard几乎同时发生) I?m sorry to hear that. 听到这事我很难过。(to hear 略先于am sorry) 3. 表示一般情况 即看不出动作的先后关系,而是表示一种情况或现象。如: Washing the car seems to be your main hobby. 擦洗汽车似乎是你的主要爱好。 None of her many lovers seemed to want to marry her. 在她的许多情人中似乎没有一个愿意娶她的。 二、不定式进行式的用法 1. 表示同时进行
