不定式和动名词做主语的区别

不定式和动名词做主语的区别 不定式和动名词都可在句子中作主语,一般说来, 有下面几点须给予注意: (1)不定式一般表示具体的、特定的行为,通常表示一种意愿、目的或者未完成的事情。;而-ing分词一般表示抽象的、一般的行为通常表示已经知道的事实或者经验。 如: To complete the program needs much effort. 完成这项计划需要很大的努力。 Riding a bike can make a man smart. 骑单车能使一个人敏捷。 (2)在疑问句中,只能用动名词的复合结构作主语。如: Is his speaking reasonable? 她的说话有道理吗? (3)在某些句型中通常要用动名词短语作主语。如:It is no use doing…/ It is no goo d doing…/ It is useless doing…/ It is worthwhil e doing…如: It is no use talking your trouble to a man like him. 跟他那样的人谈你的烦恼没有用。 (4)一般说来,作主语和表语的非谓语动词形式应一致,即:或同时为不定式,或同时为-ing分词。如: Seeing is believing. 眼见为实(from https://www.360docs.net/doc/743262521.html,)。 但是,在现代英语中,当表语用来说明主语的特定意义或具体内容时,主语和表语的非谓语动词的形式可以不一致,即,主语用动名词,而表语用动词不定式。如:Waving your hand is to say “Good-bye”. 挥手就是说“再见”。 Nodding your head is to say “Yes”. 点头就是说“对,是的”。

动名词的用法

动名词的用法及练习 你听过英文语法有动词(verb)、名词(noun);但你听过有动名词(gerund)吗 1. The girl is singing a song. 2. The girl singing now is my sister. 3. Singing is one of her hobbies(爱好). 一、名词性的动名词(Nominal Gerund) Nominal Gerund 可以加上定冠词(Definite article,如the)或不定冠词(Indefinite article,如a, an),其他可加在动名词前的还有如:my, this, some, any, all, no 等等。举例如下: 1. The mellow(愉快地) singing of the birds announces the coming of spring. (singing前加定冠词the及形容词mellow;coming 前加the) 2. We knew the robber was near when we heard a faint rustling(沙沙声) in the bushes. (rustling 前加不定冠词a及形容词faint) 从上面的例子可看出如何将一个动词转成名词;但它和真正的名词还是有区别的,那就是没有单数或复数之分。不过,有一些动名词是可以变成真正名词的喔,如:saying, writing, opening, painting, cutting, heading, feeling, being,saving, surrounding, crossing, misunderstanding 等等。它们都可以有复数的喔,方法就是在它们的后面加个s,如:paintings。 二、动词性的动名词(Verbal Gerund) 看看下面的句子: Carelessly writing essays annoys the teacher. 上面的句子里的writing是动名词,但前面有副词carelessly(粗心地),后面又有受词(Object) essays。因此writing就有动词的特征。 注意:Verbal Gerund 这类动名词的前面可不能加上任何冠词(the, a, an ...)喔。 动名词的功能与用法 一、在句子中用作主语(Subject)或主语的补语(Subject Complement): 作主语 1. Listening to music gives me pleasure. (主语Listening ) 2. Running is good exercise. (主语running) 3. Walking to school is a good idea. (主语walking) 作主语的补语 1. My cat's favorite activity is sleeping. (补语sleeping) 2. Seeing is believing. (主语seeing, 补语believing) 主语置于句尾用It + be + ... +v-ing 句型 1. It is fun speaking English. 2. It is of great importance fighting against pollution(污染). 用It is 后接no use. no good, fun 等的句型 1. It is no use learning theory without practice. 2. It is no fun being lost in rain. 用It is 后接useless, nice, good, interesting, worthwhile 等的句型 1. It is worthwhile taking this into consideration. 用There + be + no + v-ing 的句型 1. There is no joking about such matters. 2. There is no getting along with him. (简直无法与他相处) 二、动名词也可以作宾语(Object) 作动词/动词短语的宾语(置于动词或动词短语的后面) 1. I cannot help laughing. (我禁不住笑了起来)(宾语laughing) 2. You should avoid quarrelling with your sister. (宾语quarrelling) 3. You should practice speaking English more. (宾语speaking) 注意:上面三个句子中的动词:help, avoid, practice 只能用动名词作宾语。这类动词还有:dislike 厌恶admit 接受repent 后悔acknowledge 承认

动词后接不定式与动名词的区别

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。

动名词的用法

动名词 定义:动名词是动词的一种非限定形式,兼有动词和名词的特征,它可以带宾语,也能被状语修饰。动名词接宾语或状语构成动名词短语。动名词有时态和语态的变化。 基本形式:由动词原形家词尾-ing构成,与现在分词形式相同。动名词已经名词化了,而现在分词常表示动作或状态。如:a sleeping chair 躺/睡椅(动名词,表用途) a sleeping child 正在睡觉的孩子(现在分词,表状态) 一、动名词的句法功能 动名词具有名词的性质,因此在句中可以作主语、表语、宾语、定语等。 1、作主语 1)直接位于句首做主语。 Reading is an art. 读书是一种艺术。 Climbing mountains is really fun. 爬山真是有趣。 Working in these conditions is not a pleasure but a suffering. 在这种工作条件下工作不是一件愉快的事而是一件痛苦的事。 注意:动名词做主语时,谓语动词为单数 2)用 it 作形式主语,把动名词(真实主语)置于句尾作后置主语。 It is no use/no good crying over spilt milk. 覆水难收 It is a waste of time persuading such a person to join us. 劝说这样的人加入真是浪 费时间。 It was hard getting on the crowded street car. 上这种拥挤的车真难。 It is fun playing with children. 和孩子们一起玩真好。 这种用法在习惯句型中常用,常用句型: It is + no use/no good/useless/senseless/fun/enjoyable/tiring/ interesting/foolish/nice/a waste of time/a plessure… + v.ing 注意:important,essential,necessary 等形容词后面不用动名词(常用不定式)。3)用于“There be”结构中。 There is no saying when he'll come.很难说他何时回来。
