高中英语语法：不定式和现在分词
一、不定式(to do的构成
1. 不定式的构成
不定式是由不定式符号to+动词原形构成,在某些情况下to也可省略。不定式一般有时式和语态的变化,通常有下表中的几种形式(以do为例: 主动式
被动式
一般式
to do

to have been done
进行式

/
完成进行式

/
1 不定式的一般式
不定式的一般式所表示的动作通常与主要谓语的动作同时或几乎同时发生,或是在它之后发生。如:
They invited us to go there this summer. 他们邀请我们今年夏天去那儿。He stood aside for me to pass. 他站到一边让我通过。
2 不定式的完成式
不定式的完成式所表示的动作在谓语所表示的动作之后发生,它在句中可作表语、状语、宾语,有时也可作主语、定语等。如:

听老师讲课。

We are happy to have been helping each other these days. 我们很高兴这些天能互相帮助。
5 动词不定式的否定形式是由not或never加不定式构成。如:

He wished us never to meet her again. 他希望我们永远不要再见到她。
6 疑问词+动词不定式:
不定式和疑问词whether, what, which, whom, where, when, how, why等连用可以在句中起名词的作用,通常跟在tell, know, show, decide, learn, wonder, explain, advise, teach, discuss, find out等动词后面作宾语,有时也可以充当主语、表语等。如:

I mean to change it for another one. 我想换成另外一个。 Missing the train means waiting for another hour. 误了这班车就意味着再等一个小时。 Having finished the exercises, we went on to learn the new words in the next unit. 做完练习以后，我们继续学习下一单元的单词。 After a short rest, they went on working. 短暂地休息以后，他们又继续工作。 He stopped talking when the bell rang. 铃响的时候，他停止了讲
话。 While working, he stopped to talk with Tom at times. 工作的时候，他不时地停下来和汤姆谈话。注意：有时人们把 stop 后的动词不定式理解为目的状语。③动词 allow, advise, forbid, permit 等可直接跟-ing 分词作宾语，不可以接动词不定式作宾语，但可接不定式作宾语补语。如： Please permit me to say a few words. 请允许我说几句话。We don’t permit smoking here. 我们这儿不允许吸烟。④动词 need, require, want 作“需要”解时，后面接-ing 分词或不定式的被动式。如： The room wants cleaning/to be cleaned. 这个房间需要打扫。 These little children require looking after carefully/to be looked after carefully. 这些小孩需要细心地照料。⑤动词 like, hate, prefer 等后面，如表示一般性动作，多用-ing 分词；如指特定的具体的某次动作，多用不定式。如： I like s wimming, but I don’t like to swim with you. 我喜欢游泳，但我不喜欢和你一起游泳。 I prefer walking to school every day. 我情愿每天步行去学校。 I prefer to stay at home today. 今天我情愿呆在家里。⑥动词 begin, start 后面，如表示有意识地开始做某事，常用-ing 分词，否则用不定式更多一些。
如： We began to do that job last year. 我们去年开始做那工作的。 They started talking about the film at once. 他们立刻开始谈论那部电影。注：下面几种情况多用不定式作宾语： a. 当 start, begin 本身用于进行时态时。 When the teacher came into the room, he was starting to write to his parents. 老师走进教室的时候，他正开始写信给他的父母亲。 b. 当 start, begin 后接表示心理活动的动词时。 Hearing the news, he started to think of a good way to solve the problem. 一听到消息，他就开始考虑一个好办法来解决这个问题。 c. 当句子的主语是无生命的东西时。 We were about to leave when it began to rain. 我们正准备离开，天开始下雨了。 4. -ing 分词作表语的两种不同含义：①-ing 分词作表语可以表示主语的内容是什么。如：
Their job is building houses. 他们的工作是盖房子。 The real question is getting to know the needs of the people. 真正的问题是了解人民的需要。②-ing 分词作表语还可以表示主语所具有的特征。如： This story is very interesting. 这故事很有趣。 The problem is quite puzzling. 这个问题很令人困惑。①–ing 分词作定语可用来说明被修饰的名词的用途和性能。如： reading material 阅读材料 walking stick 手杖 fishing pole 鱼杆 flying suit 飞行服 writing table 写字台 listening practice 听力训练②-ing 分
词作定语还可以表示所修饰的人或物的动作或状态，在意思上接近一个定语从句，可以表示正在进行的动作，也可表示经常性动作或当时的状态。如：developing countries = countries that are developing 发展中国家 a growing city = a city that is growing 发展着的城市 an ordinary-looking house = a house that looks ordinary 看起来很普通的房子 a touching story = a story that is touching 一个动人的故事working people= people who are working 劳动人民 6. 不定式和-ing 分词作宾语补语的区别：在 see, hear, feel, watch, notice 等感官动词后，既可用-ing 分词构成复合宾语，也可用不定式构成复合宾语，两者之间有一定的区别。用-ing 分词时，表示动作正在进行；用不定式时，表示动作发生了，即动作的全过程结束了。如：Do you hear someone knocking at the door? (Someone is knocking at the door. 有人在敲门你听见了吗？ Do you hear someone knock at the door? (Someone knocked at the door just now. 你听见有人敲门了吗？ 7. 高中阶段常见的带介词 to 的短语，后接-ing 分词或名词。如： admit to（承认）, contribute to（捐助、贡献）, get down to （着手做）, give way to（让位于），keep to （坚持、遵守）, lead to （导致）,look forward to（期待）, take to（从事）, turn to （求助于）, stick to（忠于、坚持）, point to （指向、表明）, see to （注意、处理） be used to （习惯于） devote , , oneself to （献身于） be equal to （胜任的、 , 等于） be familiar to （为…… , 熟悉）. 高中阶段有一些固定的-ing 分词短语，如 generally speaking（一般来说）, judging from…（根据……来判断）, considering…（考虑到……）, talking of…（谈到……，提到……）, supposing…（假如……）等，它们的逻辑主语和句子的主语不一致。这种短语可以被称之为句子的状语，也可当作一个插入语。如：Judging from his accent, he must come from Canada. 从他的口音看他一定来自加拿大。 Considering how poor he was, we decided to let him attend the concert for free. 考虑到他是多么的穷，我们决定让他免费听音乐会。
高中英语语法之动词过去分词 简介 规则动词的过去分词一般是由动词加ed构成(具体规则见后)，不规则动词的过去分词见不规则动词表。过去分词则属于类动词 1. 及物动词的过去分词作表语,与句子主语是被动关系,表示主语的状态,不但表示被动,还表示已完成了.The cup is broken. 茶杯破了. 2. 不及物动词的过去分词作表语,与句子主语是主动关系,表示主语的状态,只表示动作的完成. He is retired. 他已退休. 3. 有些过去分词作表语时,构成的谓语很接近被动结构. 过去分词构成规则 1 、规则动词：规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同。四点变化规则： (1)、一般动词，在词尾直接加“ ed ”。work---worked---worked ,visit---visited---visited (2)、以“ e ”结尾的动词，只在词尾加“ d ”。live---lived---lived , (3)、以“辅音字母+ y ”结尾的动词，将"y" 变为"i" ，再加“ ed ”。 study---studied---studied ,cry---cried---cried , (4)、重读闭音节结尾，末尾只有一个辅音字母，先双写该辅音字母，再加“ ed ”。 stop---stopped---stopped , drop---dropped--dropped 2 、不规则动词，见不规则表 一、当过去分词作为表语 The city is surrounded on three sides by mountains. 这座城市三面环山. 【注意】过去分词作表语与被动语态的区别:过去分词作表语,主要是表示主语的状态,而被动语态则表示动作. (1) The cup was broken by my little sister yesterday. 茶杯是昨天我小妹打碎的.(是被动语态,表示动作) (2) The library is now closed. 图书馆关门了.(过去分词作表语) 【注意】过去分词表示被动或完成, -ing 形式表示主动或进行.有些动词如interest, bore, worry, surprise, frighten 等通常用其过去分词形式来修饰人,用-ing 形式来修饰物. (3) The book is interesting and I'm interested in it. 这本书很有趣,我对它很感兴趣. 二、当过去分词作为定语 作定语用的过去分词相当于形容词,其逻辑主语就是它所修饰的名词.及物动词的过去分词作定语,既表被动又表完成;不及物动词的过去分词作定语,只表完成. 1. 过去分词用作定语,如果是单个的,常置于其所修饰的名词之前. We must adapt our thinking to the changed conditions. 我们必须使我们的思想适应改变了的情况. 2. 过去分词短语用作定语时,一般置于其所修饰的名词之后,其意义相当于一个定语从句,但较从句简洁,多用于书面语中. The concert given by their friends was a success.他们朋友举行的音乐会大为成功. 3.过去分词短语有时也可用作非限制性定语,前后常有逗号. The meeting, attended by over five thousand people, welcomed the great hero. 他们举行了欢迎英雄的大会,到会的有五千多人. 4. 用来修饰人的过去分词有时可以转移到修饰非人的事物,这种过去分词在形式上虽不直接修饰人,但它所修饰的事物仍与人直接有关.
不少英语语法书上认为英语中的感官动词如feel, hear, see, look at, listen to, notice, watch等后要跟复合宾语，即"宾语+宾语补足语"并举例说：I heard him speak.我听了他的发言句中的不带to的不定式speak表示已发过言了，表示一个完成的动作I heard him speaking.我听见他在说话句中的现在分词speaking表示"正在说话"笔者认为上述的解释是不正确的下面谈谈自己的一点肤浅见解，与同行们探讨 如果按上述I heard him speak.句中的解释，speak表示"一个完成的动作"，"讲过话了"，在我听的时候，speak怎么会是一个完成的动作呢?按理可推，I heard her singing.能理解为说话的此刻她还在唱歌吗? 由此可见，"一个完成的动作"是对哪个时间参照点而言，如果是对说话的此刻而言，那么，当hear,feel,notice,watch等为过去时，不管是不带to的动词不定式，还是现在分词都表示"完成的动作" 如果hear,feel,notice,see,watch等为一般现在时或一般将来时，则不带to的不定式不可能是"一个完成的动作"如：We want to come and hear you play.能解释为说话的此刻，play是"一个已完成的动作(已演出过了)"吗? 在语言的运用中，实际上不带to的动词不定式表示整个活动(a complete activity, a complete action或a whole action)，而现在分词表示正在进行的动作(an activity in progress)或者不管是不是全过程试比较： I saw him change the wheel of his car.我看见他在换汽车轮子(意味着我看到了整个动作过程) I saw him changing the wheel of his car.我看见他换汽车轮子(可能意味着我只看到动作过程的一部分) 又如：I saw him cross the road.是指"我看到他穿过马路的整个过程"(从离开人行道到另一侧的人行道)，而I saw him crossing the road.则是指"我看到他正在穿越马路"再比较下列动
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.
专题十六倒装句和省略句重难点分析 一、倒装句 倒装句主要考查以下几个方面： ◆含有否定意味的词置于句首，用部分倒装； ◆“only+状语/状语从句”置于句首，用部分倒装； ◆so/such…that句型中，“so+形容词/副词”提前，用部分倒装； ◆表示方位的副词或介词短语放在句首，要用完全倒装。 1. 倒装句用法一览表：
2. 特别提示 (1) there be结构的倒装句型中，除了be动词之外，there后还可接lie, live, seem to be等。如：There lived an old man in the village long long ago. 很久很久以前，村子里住着一位老人。 (2) here, there, now, then, up, down, away, out等副词位于句首，主语为代词时不到装。如：Away it flew. 它飞走了。 (3) 直接引语的一部分或全部位于句首，主句倒装，主句倒装，但是主语为代词时不倒装。如：“You have to finish it tonight,” she said. “今晚你必须完成它，”她说。 (4) so位于句首不倒装的情况：
① 主语与前句相同，表赞同，译为“确实如此”。如： — Mike studies hard. 迈克学习很刻苦。 — So he does. 确实是。 ② 表示前句内容也适用于另外的人或事，前句如果列举了两种事实以上，用“so it is/was with sb./sth.”回答。如： — Tom is kind and often helps those in trouble. 汤姆很友好，经常帮助处于困境中的人。 — So it is with his father. 他父亲也是。 (5) 使用as/though进行倒装时注意： ①句首有名词，名词不能带任何冠词。如：Child as he is, he can tell right from wrong. 尽管他是个孩子，却能够明辨是非。 ②句首是实义动词时，其他助动词则放在主语之后。如果实义动词有宾语和状语，则宾语和状语随实义动词一起放在主语之前。如： Try hard as he will, he never seems to be able to do the work satisfactorily. 虽然他尽力了，但他的工作总做得不尽如人意。 (6) not until位于句首的倒装结构中，如果是复合句，只有主句用倒装，从句不用。如： Not until he loses his health will he give up smoking. 他直到失去健康才会戒烟。 二、省略句 高考命题导向：省略是一种避免重复，保持简洁的语法手段。缺少一个或一个以上的必要语言成分，但在一定语境中能够独立存在，意义明确，并且能发挥交际功能的句子叫作省略句。高考主要是考查省略在固定结构中的运用。 省略句用法一览表：
接不定式和动名词含义不同的动词 1. remember(记得)，forget(忘记)，regret(后悔)后接不定式指该不定式所表示的动作还未发生，后接动名词(有时可用完成式)，则指该动名词所表示的动作已经发生。比较。如：Remember to post the letter. 记住把这封信寄了。(“寄信”未发生) I remember posting the letter. 我记得寄了那封信。(“寄信”已发生) He forgot to pay me the money. 他忘记要给我付钱了。(“付钱”未发生) He forgot paying me the money. 他忘记曾给我付过钱。(“付钱”发生了) 2. try 后接不定式表示设法做某事，接动名词表示做某事试试(看有什么效果)。如： I’ll try to come tomorrow. 我明天设法来。 Let’s try knocking at the back door. 咱们敲敲后门试试。 3. mean 后接不定式表示打算(想要)做某事，接动名词表示意味着(要)做某事。如： He means to be a teacher. 他打算当老师。 He did not mean to hurt you. 他不是有意要伤害你。 This illness will mean going to hospital. 得了这种病就意味着要住院。 4. stop 后接动名词表示停止做某事，接不定式表示停下正在做的事去做另一事。如： He stopped speaking, and there was not a sound in the room. 他停止讲话，房里一点声音也没有了。 He stopped to listen, but there was no more sound. 他停下来听，但再也没有听到什么声音。 【注】后接不定式时，不定式不是宾语，而是目的状语。 5. can’t help后接动名词表示禁不住去做某事，接不定式表示不能帮助做某事。如： He couldn’t help crying when he heard the news. 他听到这个消息时禁不住哭了。 The medicine can’t help to get rid of your cold. 这药不能帮你治好感冒。 6. go on 后接不定式表示做完某事后接着做另一事，接动名词表示继续做正在做的事。如： You oughtn’t to go on living this way. 你不应该再这样生活下去了。 Go on to do the other exercises after you have finished this one. 做完这个练习后, 请接着做其他的练习。 【注】也人认为go on doing sth中的doing是现在分词而不是动名词。

巧记跟不定式和动名词做宾语的动词用法 语法体现语言的规律,学好英语离不开语法学习。其中，动词的用法是重点，也是难点。对于谓语动词和非谓语动词的用法，学生普遍感到困难。学生感到50多个动词，用法难以掌握，但调整了单词的排列顺序，根据汉意编写顺口溜会方便记忆： （一）跟不定时作宾语的动词有： 打算(intend)计划(plan)和期盼(expect/desire) 假装(pretend)喜欢(would like/love/prefer)表祝愿(wish) 决定(decide)同意(agree)来帮助(help) 设法(manage)说服(persuade)不拒绝(refuse) 好像(seem/appear)答应(promise)做努力(attempt) 选择(choose)询问(ask)多学习(learn) 告诉(tell)失败(fail)也付得起(afford) 不定式宾语要牢记！ （二）跟动名词作宾语的动词有： 考虑（consider）完成（finish）多练习（practise） 避免（avoid）冒险（risk）求建议（suggest/recoomend） 面对（face）喜欢（enjoy/appreciate）和介意(mind) 允许（allow）承认（admit/permit）或放弃(give up/abandon) 推迟（put off/delay/postphone）逃避（escape）不原谅（excuse/pardon）提及（mention）坚持(keep/insist on）要想象（imagine/fancy） 还有词组feel like 和can’t stand！ 瞧！，我们就这样快快乐乐地记住了吧！ （三）在动词remember, try, regret, forget, need/want/require， stop, mean等后跟动名词V-和不定式意义不同，巧记一句话（记住努力；后悔忘记；需要停止；很有意义），学习采用对比法： remember to do something记着去做某事（现在还没有做） remember doing something记着曾做过某事（以前做过某事） try to do something努力、尽力做某事 try doing something试着做某事（看能否达到预期的结果） stop to do something开始做某事（停下正在做的事，开始做另一事） stop doing something停止做某事（停止正在做的事） regret to do something对将来做的事感到遗憾、惋惜 regret doing something对已经做过的事感到后悔
何时用不定式何时用分词和动名词 Ⅰ.动名词和不定式做主语的相同点 1.不定式短语和动名词做主语时，常常为了保持句子的平衡，用it来做形式主语，如： It is not easy to learn English well. It is no use asking him for help. 2.如果主语用了不定式,表语和宾语也要用不定式;主语用了动名词,表语和宾语也要用动名词,这在英语中称为对称性,如: To see is to believe. = Seeing is believing. (眼见为实) (85)It is better to stay home than _A__ out. A. to go B. going C. go D. gone Ⅱ.动名词和不定式做主语的不同点 1.不定式做主语常表示具体的某一动作;表示泛指或一般的抽象的概念时,多用动名词,如: (92)_B_ is a good form of exercise for both young and old. A. The walk B. Walking C. To walk D. Walk 2.在”There/It +be+ no use(good/help/need)”之后常用动名词做主语,而少用不定式,如: It /There is no use crying over the split milk. It /There is no help taking this medicine. ★但是如果该句型中用了for引出不定式的逻辑主语,就只能用不定式,如: (93) There is no good for us to do that exercise. 3.不定式可以和when, where, how, what, whether等连用,在句子中做主语,宾语和表语,而动名词则不能,如: How to solve the problem is a hot potato. Where to put the box seems hard to decide. Whether to do it hasn’t been decided. What to do next is up to you. 时态、语态及其基本用法 A. 不定式 1．不定式的时态、语态有三种形式：①一般式，如，to write / to be written ;②进行式，如，to be writing / to have been writing;③完成式，如，to have written / to have been written 。 2．基本用法 ①不定式的一般式，表示的动作与谓语动词表示的动作同时发生，有时也发生在谓语动词表示的动作之后。如： He seems to know this.(=It seems that he knows this.) I hope to see you again.(=I hope that I’ll see you again.) He doesn’t like to be laughed at. (=He doesn’t like that he is being laughed at.) ②不定式的进行式，表示不定式的动作正在进行，与谓语动词表示的动作同时发生。如： When the mother went into the room, the boy pretended to be sleeping. (=… , the boy pretended that he was sleeping .) I heard the English song being sung by him. (=I heard that the English song was being sung by him.) ③．不定式的完成式，表示的动作发生在谓语动词表示的动作之前。如： I am sorry to have kept you waiting so long. (= I am sorry that I kept you waiting so long. ) Having been well written, the book was translated into many languages. (=Because it had been well written, …) B. 分词 1.只有现在分词才有时态和语态形式的变化。现在分词的时态、语态有两种形式：①一般式，如，doing / being done;
动词不定式、动名词的用法和区别 动词不定式：动词不定式是由to + 动词原形构成，在句中起名词，形容词和副词的作用，可以担任除谓语以外的其它任何成分。 1. 动词不定式作主语： To mast a language is not an easy thing. / To teach English is my favorite. 动词不定式作主语时可以放在后面，而用it 作形式主语放在原主语的位置上。 It's very kind of you to have given us much help. 2. 动词不定式作宾语： 某些及物动词可以用动词不定式作宾语，这些动词有decide, begin, help, begin, want, wish, like, forget, learn, ask. I like to help others if I can. 3. 动词不定式作宾语补语。 We expect you to be with us. 我们希望你和我们在一起。/ Please ask him to come here quickly.请叫他快过来。 4. 动词不定式作表语： What I should do is to finish the task soon. / The most urgent thing is to find the boy immediately. 5. 动词不定式作定语： There are many ways to solve the problem. / I have something important to tell you. 6. 不定式作状语： We went to the hospital to see our teacher. / She is making a test to get a kind of useful medicine from a Tibet flower. 动词不定式的否定形式：not + to + 动词原形 The teacher told us not to swim in that river. 老师告诉我们不要在那条河里游泳。 It's unfair not to tell us. 没告诉我们真是不公平。 带疑问词的不定式： 疑问词who, what,which,when, where, how, why 可以加在不定式的前面，构成不定式短语，使含义更加具体。Where to go is not known yet. I don't know when to begin.。 Can you tell me where to get the battery. Do you know how to get to the station. 带逻辑主语的不定式： 动词不定式可以带有自己的逻辑主语，构成方法是：for + 逻辑主语+ 不定式。 注意：逻辑主语用宾格形式，for 本身无实际意义，它只表明后面的主语从逻辑上分析是不定式的主语。 It's necessary for us to help each other. / There are much work for me to finish, 动词不定式的被动形式：表示不定式动词同所修饰的名词是被动关系。 He is the man to be examined. 他是受检查的人。/ There are much work to be done. 有好多工作要做。 ●动名词 动名词是由动词原形+ ing 构成，同现在分词形式一样，在句中可作主语，宾语，表语和定语。 1) 动名词作主语： Talking like that is not polite. / Learning from others is important . / Putting on more clothes is not so good . （注：动名词可以象动词不定式一样，用it作形式主语，而把动名词写在后面做真正的主语。）It's no use waiting here, let's go home. / It's very difficult climbing this mountain. 2) 动名词作表语 The nurse's job is looking after the patients. 3)动名词作宾语 有些动词须用动名词来作宾语,它们是begin, mind, suggest, finish, stop, need, enjoy, miss, keep. Please stop smoking in the house. / I like reading in the forest. / Do you mind my opening the windows? 4）动名词作定语 She is studying in the reading room. / He slept in the sleeping bag. （动名词的否定形式：not + 动名词） He pretend not knowing it at all. 他假装全然不知。/ We considered not doing it now. 我们考虑现在不做这件事。 动名词的被动形式：当动名词和它的逻辑主语是被动关系时，用动名词的被动形式来表示。）His being looked down upon made him sick. / I can't really stand being treated like that.
高中英语语法：不定式和现在分词 一、不定式(to do的构成 1. 不定式的构成 不定式是由不定式符号to+动词原形构成,在某些情况下to也可省略。不定式一般有时式和语态的变化,通常有下表中的几种形式(以do为例: 主动式 被动式 一般式 to do to be done 完成式 to have done to have been done 进行式 to be doing / 完成进行式 to have been doing /
1 不定式的一般式 不定式的一般式所表示的动作通常与主要谓语的动作同时或几乎同时发生,或是在它之后发生。如: They invited us to go there this summer. 他们邀请我们今年夏天去那儿。He stood aside for me to pass. 他站到一边让我通过。 2 不定式的完成式 不定式的完成式所表示的动作在谓语所表示的动作之后发生,它在句中可作表语、状语、宾语,有时也可作主语、定语等。如: She seemed to have heard about this matter. 她似乎已听说过这件事。 I am sorry to have kept you waiting so long. 我很抱歉让你等了这么久。 I meant to have told you about it, but I happened to have an important thing to do. 我本来想告诉你这件事的,但我碰巧有一件重要的事要做。 It has been an honor for me to have traveled so much in your country. 对我来说,在你们国家旅行这么多地方是一件很荣幸的事情。 3 不定式的进行式 不定式的进行式表示正在进行的与谓语动词同时发生的动作。它在句中可以用作除谓语以外的所有成分。如: It’s nice of you to be helping us these days. 你真好,这些天一直帮我们。 He pretended to be listening to the teacher carefully. 他假装在认真地 听老师讲课。
动词不定式和动名词是英语非谓语动词的两个重要部分 一、作主语 1、不定式作主语：动词不定式可直接用作主语, 句子的谓语动词常用单数。 To get there by bike will take us half an hour. 对于主语较长的不定式，可以用it 作形式主语。例如： It's our duty to take good care of the old.How long did it take you to finish the work It is difficult for us to finish writing the composition in a quarter of an hour. It seemed impossible to save money.It's kind of you to help me with my English. 2、动名词作主语：动名词也可直接用作主语，或者用it 作形式主语。例如： Learning without practice is no good.It's no good reading in dim light.It's no use sitting here waiting.It's dangerous swimming in the sea in windy days.There is no saying what will happen next. 3、动词不定式和动名词作主语的区别 (1)不定式作主语经常表示具体动作，或者表示将要进行的动作。而动名词作主语经常表示 抽象的一般性的动作。例如：It's no good for you to eat so much fat. ( 有具体的人for you) It's no good eating too much fat. ( 泛指 ) (2) 不定式的逻辑主语常用 of, for 表示；动名词逻辑主语则常用物主代词、名词、代词表示。例如：It is stupid of you to write down everything the teacher says. (of you) It's no use your pretending that you didn't know the rules. (your) The doctor suggested them having their health check-up once a year. 二、作宾语 1、不定式作宾语 (1) 以下动词后 , 一般只用不定式作宾语 .如 :agree, attempt ， apply， ask, aim, arrange, beg ，choose, decide, demand, expect, fail , help, hope, lean, long, manage, offer, plan, prepare, pretend, promise, refuse, wish afford 等。 I decided to ask for my money back. I decided that I would ask for my money back. When our visit to the farm was over, we expected to start back on foot.

You must give up smoking, for it does too much harm to your health. (2)介词后只能接动名词做宾语 I should go to attend the birthday celebration instead of staying at home. What about inviting Li Jun to make a speech (3)少数特殊结构中只用动名词做宾语。它们可以看作是省略的介词的形式。例如： have difficulty prevent/stop (in) doing sth. have ? (from) doing sth. no trouble (in) doing sth.lose no ti me (in) there is no use (in) doing sth. doing sth. 3、不定式与动名词做宾语的区别 (1)动词后是接不定式还是动名词作宾语，主要是根据使用习惯。有些动词后一般只接不定
动名词作主语和动词不定式做主语的区别? 动词不定式与动名词的区别：）to+V 放句首为动词不定式，用法与V+ing差不多，多用于后面所说的事情还没有发生。例：To be a author is my dream. V+ing 放句首是动名词，其相当于名词，例：Doing lots of exercise is good for health. 一般来讲，to+ v. 表主动，表将来，表一次行动作。-ing 表主动，表进行。动词不定式与动名词的一些用法：）不定式与动名词都可以在句中作主语、宾语、表语和定语,但用法不尽相同。1．作主语一般情况下,不定式与动名词作主语可以互换,也常常可以用it充当形式主语,而把不定式和动名词放在句子的后半部分。但二者也有区别,不定式常常指某次具体的、将要发生的行为;而动名词则表示一般的、抽象的行为。例如: To save money now is not easy. 现在攒钱不容易。Saving money is a good habit. 攒钱是个好习惯。2．作定语不定式多为后置定语,动名词多为前置定语;不定式多表示将来的动作,动名词只能表示事物的属性、用途等。例如: He is looking for a room to live in.他正在找一间房子去住。Take these sleeping pills and you\'ll sleep better. 吃了这种安眠药,你会睡得更好。3．作宾语：有些动词后只能跟不定式作宾语,不能跟动名词作宾语;有些动词后常跟动名词作宾语,不能跟不定式作宾语;有些动词后跟不定式和动名词作宾语皆可, 1、动名词做主语往往表示普通的、一般的行为，不定式做主语常表示某次具体的行为。例 如：Collecting inform ation about children’s health is his job. 收集有关儿童健康的信息是他的工作。It’s necessary to discuss the problem with an experienced teacher. 与一位有经验的老师讨论这个问题是有必要的。2、常用不定式做主语的句型有：（1）It’s difficult (important, necessary) for sb. to do （2）It’s kind (good, friendly, polite, careless, rude, cruel, clever, foolish, brave) of sb. to do. 3、常用动名词做主语的句型有：It’s no good (use, fun) doing. It’s (a) waste of time one’s doing.另:1)动名词作主语通常表示抽象动作；而不定式作主语表示具体动作。Smoking is prohibited(禁止)here．这里禁止抽烟。(抽象) It is not very good for you to smoke so much．你抽这么多烟对你身体很不好。(具体) (2)动名词作主语时，通常用以表示一件已知的事或经验。 不定式短语通常用来表示一件未完成的事或目的。Climbing mountains is interesting．爬山很有趣。(经验) Driving a car during the rush hour is tiring．在高峰时刻开车令人厌烦。(经验) (3）不定式做主语，一般用it当形式主语，把作主语的不定式短语后置。It took me only five minutes to finish the job.
