总结动词不定式的使用方法:用途、结构与注意事项

总结动词不定式的使用方法:用途、结构与注意事项

总结动词不定式的使用方法:用途、结构与注意事项动词不定式是一种由动词原形加上“to”构成的结构,在英语中具有多种用途和结构。

首先,动词不定式可以用作动词的宾语或宾语补足语。

例如,“I want to learn English”中的“to learn”就是动词不定式作为动词“want”的宾语。

此外,动词不定式还可以用来表示目的或意图。

比如,“She went to the store to buy some groceries”中的“to buy”表示了目的,即购买食品。

同时,动词不定式还可以用在感官动词(如see, hear, watch 等)后作宾语补足语。

比如,“She saw him leave the house”中的“leave”就是动词不定式作为宾语补足语的用法。

此外,动词不定式还可以用在形容词后面,起到修饰作用。

例如,“It's important to study regularly”中的“to study”修饰了形容词“important”。

总的来说,动词不定式在英语中的使用非常灵活,可以用来表示各种不同的语法功能。

然而,在使用动词不定式时也需要注意一些细节。

首先,有些动词后面必须跟动词不定式作为宾语,而有些动词则只能跟动词的-ing形式作为宾语。

例如,“I enjoy reading”中的“reading”是-ing形式,而“I want to read”中的“to read”是不定式形式。

此外,有些动词后面可以跟动词不定式也可以跟动词的-ing形式,但意思可能会有所不同。

比如,“remember”后面可以接动词不定式或-ing形式,但表示的意义有所区别,例如“I remember to call her”和“I remember calling her”。

在动词不定式的结构方面,动词不定式通常由“to”加上动词原形构成,但有时候也会有一些特殊的结构。

比如,有些动词后面要求省略“to”,如“let, make, help”等。

动词不定式的归纳总结动词不定式是由“to+动词原形”构成的,否定形式为“not to+动词原形”构成的,这里的to没有词义,只是为了构成不定式的一种符号,是非谓语动词形式的一种,动词不定式在句中不能独立作谓语,除了不能作谓语以外,其他成分都可以作,因此,在句中可以作主语、表语、宾语、定语、状语和补足语。

❶ 动词不定式做主语:这种情况一般要改成it作形式主语的形式,后接不定式,为了避免头重脚轻。

●“It is+形容词+for sb.+to do sth.”意为“做某事对某人来说是…的”中句中的形容词多为描述性的词语,不对人或物的品格进行评价,如difficult, easy, hard, inportant, dangerous, inpossible等。

eg To learn English is very important for me 对我来说学英语很重要。

=It is very important for me to learn English.For you to make more friends is a good plan. 广交朋友是个好办法。

= It's a good plan for you to make more friends.●“It is+形容词+of sb.+to do sth.”意为"做某事对某人来说是…的”。

eg It was stupid of him to press the emergency button. 他按了紧急按钮,这真愚蠢。

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 examined.(不定式作状语)My work is to clean 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 nothing to do now.( We have nothing to do now.) There is nothing to be done now.(We can do nothing now.)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 sthHe seems to know this.I hope to see you again. = I hope that I'll see you again.我希望再见到你。

2) 完成式:表示的动作发生在谓语动词表示的动作之前。

I'm sorry to have given 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 eating something.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后可接不定式构成不定式短语,在句中作主语、宾语、表语等。

如:①When to leave for London has not been decided yet. (不定式在句子中做主语)②Mr. Smith didn't know whether to leave or stay there. (不定式在句子中做宾语)③I asked Professor Xu how to learn English well. (不定式在句子中做直接宾语)④The question was where to get the medicine needed. (不定式在句子中表语)以上例句中疑问词+不定式部分,均可转换为相应的从句形式。

如:①When we s hall leave…③…how Icould learn……经常在这种结构中使用的动词有:consider,decide,discover,explain,find out,forget,hear,know,lea rn,observe,understand,wonder等。

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.骑自行车到那儿将花费我们半个小时。

To make up for lost time is not possible.要弥补失去的时光是不可能的。

To lean out of the window is dangerous.身子探出窗外很危险。

如:①It+be+名词+to doIt's our duty to take good care of the old.照顾老人是我们的责任。

It is an offence to drop litter in the street.在马路上乱丢废物是违章的。

②It takes sb+some time+to doHow long did it take you to finish the work?你花了多少时间来完成这项工作?③It+be+形容词+for sb+to doIt is difficult for us to finish writing the composition in a quarter of an hour.我们难以在四分之一小时内完成这篇作文。

It is stupid of you to write down everything (that) the teacher says.你把老师说的所有东西都记下来的行为是很愚蠢的。

④It seems(appears)+形容词+to doIt seemed impossible to save money.在句型③中,常用表示客观情况的形容词,如:difficult,easy,hard,important,impossible,necessary 等;在句型④中,常用careless,clever,good,foolish,honest,kind,lazy,nice,right,silly,stupid,wise等表示赞扬或批评的词。

在不定式前的sb,可看作其逻辑主语。

这一句式有时相当于Sb is+形容词+to do句式,如:It's kind of you to help me with my English.=You are kind to help me with my English.⑤It + 不定式结构可位于believe/consider/discover/expect/find/think和wonder之后He thought it would be safer to go by train.他认为乘火车比较安全。

He will find it is hard to make friends.他会感觉到交朋友困难。

⑥不定式的完成式也可作句子的主语To have made the same mistake twice was unforgivable.两次犯同样的错误是不可原谅的。

Kind,nice,stupid,rude,clever,foolish,thoughtful,thoughtless,brave,considerate(考虑周到的),silly,selfish(自私的)例句:It was silly of us to believe him.我们真愚蠢,竟然相信了他。

It seemed selfish of him not to give them anything.他不给他们任何东西,这显得太自私了。

注意:(1)其他系动词如,look,appear等也可用于此句型(2)不定式作为句子成分时,动词用单数形式。

(3)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.眼见为实。

(错)It is to believe to see.作宾语1) 以下动词后,只能跟不定式作宾语afford(付得起),agree(同意),aim(力求做到),appear(显得),arrange(安排),ask(要求),attempt (试图),care(想要),choose(决定),claim(声称),condescend(屈尊),consent(准许),decide (决定),demand(要求),determine(决心),endeavor(竭力),expect(期待),fail(未履行),help (帮助),hesitate(犹豫),hope(希望),learn(学会),manage(设法),neglect(疏忽),offer(主动提出),plan(计划),prepare(准备),pretend(假装),proceed(接着做),promise(答应),prove(证明),refuse(拒绝),resolve(解决),seem(觉得好像),swear(发誓),tend(往往会),threaten(预示),undertake(承诺),volunteer(自愿做),vow(发誓),want(想要),wish(希望)举例:The driver failed to see the other car in time.司机没能及时看见另一辆车。
