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.

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)

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: _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:

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.

动名词作主语

动名词作主语

————————————————————————————————作者:————————————————————————————————日期: ?

动名词作主语 如果一个动词加上了ing变成了名词,那么这个词称动名词。动名词是一种兼有动词和名词特征的非限定动词。它可以支配宾语被副词修饰。动名词有时态和语态的变化。 由于动名词是由动词变化而来,它仍保留着动词的某些特征,具有动词的某些变化形式,用以表达名词所不能表达的较为的意念。动名词的名词特征表现在它可在句子中当名词来用,作主语、宾语、表语、定语。它也可以被副词修饰或者支配 动名词的作用 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。 作主语 Reading is an art. 读书是一种艺术。 Climbing mountains is really fun. 爬山真是有趣。 Working inthese conditions is not a pleasure but a suffer.在这种工作条件下工作不是一件的事而是一件痛苦的事。 动名词作主语,在动词的基础上加Ing,使该动词或动词短语,有名词的各种特征,可作名词灵活使用。如: 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 It was hard getting onthe crowded street car. 上这种拥挤的车真难。 Itis funplaying with children.和孩子们一起玩真好。 There is no joking about such matters. 对这种事情不是开玩笑。 动名词作主语的几种类型 动名词可以在句子中充当名词所能充当的多种句子成分。在这里仅就动名词在句子中作主语的情况进行讨论。 动名词作主语有如下几种常见情况: 1. 直接位于句首做主语。例如: Swimming is a good sport in summer. 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。 动名词做主语时,不太常用 it 作先行主语,多见于某些形容词及名词之后。例如: It is no use telling him not toworry. 常见的能用于这种结构的形容词还有:better,wonderful,enjoyable,interesting,foolish,difficult ess,senseless,worthwhile,等。 注意:important,essential,necessary 等形容词不能用于上述结构。 3.用于“Therebe”结构中。例如: There is no saying when he'll come.很难说他何时回来。 4. 用于布告形式的省略结构中。例如: Nosmoking ( =No smoking is allowed (here) ). (禁止吸烟) No parking. (禁止停车) 5.动名词的复合结构作主语 当动名词有自己的逻辑主语时,常可以在前面加上一个名词或代词的所有格,构成动名词的复合结构(——这时,名词或的所有格做动名词的逻辑主语)。动名词的复合结构也可以在句中作主语。例如: Their coming to help was a greatencouragement to us. 6.例词

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. 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) It is better to stay home than _A__ out. A. to go B. going C. go D. gone

(禁止吸烟) No parking. (禁止停车) 5. 动名词的复合结构作主语

Climbing mountains is a good form of exercise. 二、动名词、现在分词和动词不定式都可以作定语 1.动名词作定语时,和它所修饰的名词之间没有逻辑上的主谓关系,只表示被修饰名词的一般用途,必须位于名词之前。如: There is a swimming pool in our school. 2.现在分词作定语时,和它所修饰的名词之间有逻辑上的主谓关系,表示所修饰名词的特征。如: Listen to the singing bird. Who is the boy running towards us。 3.动词不定式作定语时,当所修饰的名词指人时,和它所修饰的名词之间有逻辑上的主谓关系。如: He is always the first to come to school. 当所修饰的名词指物时,和它所修饰的名词之间有逻辑上的动宾关系。如: I have a meeting to attend. 如果作定语的动词不定式中的动词是不及物动词,需加上相应的介词。如:
