动词不定式

意义、形式和特征

b)动词不定式可以被状语修饰。如:

动词不定式加宾语或状语构成动词不定式短语,如上二例中的to study Japanese和to fall heavily。

3)动词不定式的非动词特征

用法动词不定式具有名词、形容词和副词的特征,所以它在句子中可用作主

语、表语、宾语、定语和状语。

1)主语

To lean out of the window is dangerous.把身子伸出窗外是危险的。

To talk with him is a great pleasure.和他谈话是一件非常愉快的事。

To die for the people is a glorious death! 为人民而死,虽死犹荣。

动词不定式短语作主语时,往往放在谓语动词的后面,而在句首用引词"作语法上的主语。上述两句即可改为:

It is a glorious death to die for the people.

注意也常用"It is+形容词+动词不定式短语"这样的句型:

Do you like to watch football matches? 你喜欢看足球赛吗?

Learn to walk before you run.先学走后学跑。

We decided to make changes in our plan.我们决定把计划做些修改。

[注三] 注意有些用作句子独立成分的习惯语,如to begin with(首先),to conclude(最后),to be sure(当然),to tell you the truth(老实对你说)等。

疑问词 + 动词不定式

疑问代词who,what,which和疑问副词when,where,how等后加动词不定式,构成一种特殊的动词不定式短语,可在句子中作主语、宾语、表语等成分。如:

动词不定式复合结构"for + 名词(或代词宾格) + 动词不定式"

在这种结构中的for本身无意义。名词(或代词宾格)形式上是for的宾语,但在逻辑上可以说是动词不定式的主语。这种不定式复合结构在句子里可作下列成分:

1)主语

For us to learn foreign languages is important.学习外语对我们来说是重要的。

在句中,for us在逻辑上是to learn foreign languages的主语。这种结构作主语时,和简单的动词不定式结构一样,一般都用引词讧来代表并放在句首,"for + 名词 (或代词宾格) + 不定式"则放在句末。如:

It is important for us to learn foreign languages.

It is necessary for us to learn from each other.我们必须相互学习。

2)表语

It is for you to decide.这得由你决定。

3)宾语

I saw him go out.我看见他出去了。(saw与go out两个动作同时发生)

Would you help me put things in order before we leave?在我们离开之前,你帮我整理一下东西好吗?(would help和put同时发生)

2)但在很多情况下,动词不定式一般式表示的动作发生在谓语动词表示的动作之后;如:

I hope to see you again.我希望再见到你。(to see这个动作发生在hope 之后)

The boy said he wanted to be a scientist.这男孩说他想做一个科学家。(to be在wanted之后)

动词不定式的时态形式

动词不定式通常有三种时态形式,现以write为例:

一般式to write进行式to be writing

完成式 to have written

动词不定式完成式的用法

动词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 kept you waiting.对不起,叫你久等了。(to have kept 发生在am所表示的时间之前)

She seems to have read the book before.她好像看过这本书。(to have read 发生在seems所表示的时间之前)

The battery appears to have run down.这组电池好像已经用完了。(to have run down发生在appears所表示的时间之前)

但在下面句子中,动词不定式表示"动作没有完成":

We were to have met at ten.我们本来是约定十点钟见面的。(结果未见面) 动词不定式进行式的用法

动词不定式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。如:He see ms to be recovering.他看来在康复。

分裂不定式

有时在不定式符号"to"和动词原形之间插入一个副词,这种现象叫做分裂不定式(split infinitive)。插入动词不定式的副词,习惯上往往与不定式动词连在一起。如:

He likes to half close his eyes.他喜欢半闭着眼睛。

Our object is to further cement friendly relations between the two countries.我们的目的是进一步加强两国之间的友好关系。

At first he wasn't interested in bookkeeping,but later he began to actually like it.起初他对会计工作没有兴趣,但到后来倒喜欢起它来了

2)作表语:

动词不定式的用法有哪些

动词不定式的用法有哪些? 动词不定式在中学英语中应用非常广泛,一方面在句中可起名词、形容词或副词的作用,同时也可在句中作主语、宾语、定语、状语和宾语补足语。动词不定式的形式是:to +动词原形,但to有时要省去。而动词不定式在具体运用时用不用to,取决于谓语动词的用法。现就以下几方面介绍如下: 一、不定式结构 1. 带to的不定式结构能直接跟带to的不定式结构的动词主要有:want, expect,plan,begin,start,ask, tell, hope, learn, try, decide, forget, remember, like, love, stop, go, come等。 如:I want to go to the movies with you. 我想跟你一起去看电影。 Don’t forget to turn off the light before you leave. 在你离开之前别忘了关灯。 注意:动词不定式的否定形式是在不定式前直接加not,即not to do sth.。 如:Dave told me not to wake up Kate. 大卫告诉我别叫醒凯特。 2. 不定式有时和一连接代(副)词一起构成宾语。 如:I don’t know what to say.我不知道说什么。 3. 不带to的不定式结构以下几种情况使用不带to的动词不定式: (1)在固定词组had better之后。注意:had better的否定形式是had better not do sth.。 如:You had better go home now. 你最好现在回家。 It’s cold outside. You’d better not go out. 外面很冷,你最好不要出去。 (2)在let, make, see, feel, watch, hear,have等感官或使役动词后,要跟不带to的动词不定式作宾语补足语。 如:I made them give me the money back. 我迫使他们把钱还给我。 I didn’t see y ou come in. 我没看见你进来。 (3)在引导疑问句的why not之后。Why not+不带to的不定式是Why don’t you do的省略,可以用来提出建议或劝告。 如:Why not take a holiday?=Why don’t you take a holiday? 为什么不休个假呢? (4)不定式动词在介词but, except, besides后面时,如这些介词前有实义动词do的各种形式,则后接不带to的不定式,否则带to。 如:I have no choice but to accept the fact. 除了接受这个事实我别无选择。What do you like to do besides swim? 除了游泳你还喜欢做什么? (5)为了避免重复,不定式可省去to。 如:I’m really puzzled what to think or say. 对于想什么或说什么,我真

英语动词不定式大全

英语动词不定式大全 动词不定式是一种活跃的非谓语动词。它在句中起的是名词。形容词或副词的作用,可在句子中作主语。宾语。定语。状语和宾语补足语。动词不定式的形式是"to +动词原形",但to有时要省去。动词不定式在具体运用时,用不用to,取决于谓语动词的用法: 一。带to的不定式结构 1.我们学过的能直接跟带to的不定式结构的动词主要有:want, ask, tell, hope, learn, try, decide, forget, remember, like ,love, stop, go, come 等。 2.动词不定式的否定形式是在不定式前直接加not,即not to do sth.。例如: Jim told me not to wake up Kate.吉姆告诉我别叫醒凯特。 二。不带to的不定式结构 以下几种情况使用不带to的动词不定式: 1.在固定词组had better之后。注意:had better的否定形式是had better not do sth.。例如: You had better go home now.你最好现在回家。 It's cold outside. You'd better not go out.外面很冷,你最好不要出去。 2.在let,make,see, feel, watch,hear等感官或使役动词后,要跟不带to 的动词不定式作宾语补足语。例如: I made them give me the money back.我迫使他们把钱还给我。 I didn't see you come in.我没看见你进来。 3.在引导疑问句的why not之后。 "Why not+不带to的不定式"是Why don't you do…的省略,可以用来提出建议或劝告。例如: Why not go with us。为什么不和我们一起去呢。 Why not take a holiday。=Why don't you take a holiday。为什么不休

引言:英语中语气、语态的变化都是通过动词变形实现的,所以掌握动词的变形举足轻重。切记:要把示意动词充当谓语和非谓语动词要分开,非谓语顾名思义 已经不是谓语动词了,所以它的用法和变形与动词时态是不一样的!

It is no use crying.哭没有用。 It is no good objecting.反对也没有用。 It is a great fun playing football .打篮球很有趣。 It is a waste of time trying to explain .设法解释是浪费时间。

(完整版)非谓语的用法总结

非谓语动词的用法总结 李靖 非谓语动词(不定式、动名词、分词)不是真正意义上的谓语动词,在句中都不能单独作谓语。但都具有动词的某些特点,可以有自己的宾语或状语,构成非谓语动词短语。不定式表目的,表将来;动名词表主动,表进行;过去分词表被动,表完成。 一.作主语( 动名词、不定式、过去分词前面加being, 动名词做主语谓语动词用单数) 1)不定式、动名词都可做主语,但是动名词做主语多指抽象的概念性的动作,可以是多次的经常的行为;不定式多表示具体的动作,尤其是某一次的动作。如: Playing with fire is dangerous. 玩火危险。(泛指玩火) To play with fire will be dangerous. 玩火会发生危险。 2)用动名词做主语的句型: It’s no use/no good/pleasure doing sth 做.......没有用处/好处/乐趣 It’s a waste of time doing sth 做.... 浪费时间 It is worth doing sth 值得做某事 It is no use crying over spilt milk. 覆水难收 It is worth making an appointment before you go. 去之前预约一下是值得的。 3)不定式做主语的句型. It is + adj +for sb to do sth. 比较:表示人的品质时只能用of sb 如considerate/kind/nice/foolish/stupid/rude/cruel /wise/clever/brave/selfish/crazy/good/careful/careless/impolite/right/wrong等单词出现 时。 It is silly of you to say so. It is important for us to learn English well. It is a must/ a necessity for us to have a good command of the English language. 4) “Wh- + to 不定式”可做主语。如: When to leave hasn’t been decided yet.什么时候动身还没定呢。 Whether to drive or take the train is still a problem.是自驾车还是乘火车仍是一个问题。 5)一般情况下,不定式和动名词作主语,谓语动词一般用单数形式。如: Seeing is believing.= To see is to believe 眼见为实。 . Planting flowers needs constant watering. 但and连接的多个动名词作主语,谓语动词大多用复数(如果前后动名词的语义一致, 谓语一般用单数)。如:Lying and stealing are immoral. 说谎与盗窃是不道德的。 6) 动名词前面可以加上形容词性物主代词构成动名词的复合结构。如: ----- What made him angry? ------ Mary’s /My/His/Her /Their/ The boy’s/ The president’s being late(made him angry. 7being,构成动名词,做主语。如: . Being examined twice a year , driver must obey in this city. 经典练习:
