篇3:小议动词不定式的基本用法

一、做主语

如:To learn English well is very important.(学好英语是很重要的。)To stop the work now seems impossible.(现在把这个工作停下来似乎不可能。)但在很多情况下,为了保持句子结构平衡,避免头重脚轻的现象,用it形式主语,把真正的主语动词不定式(或短语)放在后面。如:It's important for students to use English every day.(对学生们来说,每天使用英语是重要的。)It is necessary to learn English.(学习英语是必要的。)

二、做表语

1. 不定式做表语一般表示具体动作,特别是表示将来的动作

如:Today's job is to teach you how to study English.(今天的任务是教你如何学习英语。)

2. 如果主语是以hope,idea,problem,wish等为中心的名词,不定式做表语是对主语起补充说明作用,说明主语的具体内容

如:My only wish is to do something for the public.(我唯一的愿望是为公众做些事。)

三、做宾语

1. 许多动词(如want,learn,decide,hope,plan等)后都可直接跟动词不定式做宾语。

如:I want to go to Beijing tomorrow.(我想明天去北京。)

He learnt to skate on real ice.(他在真冰上学滑冰。)

2. 疑问词+不定式一起构成宾语。

如:I don’t know what to do.(我不知道该做什么。)

He taught me how to swim.(他教我怎样游泳。)

3. 不定式有时用it代替,做形式宾语,把真正做宾语的动词不定式放在句末

如:He feels it his duty to help the poor.(他觉得帮助穷人是他的责任。)

He finds it very difficult to study English well.(他发现学好英语很难。)

四、做宾语补足语

1. 在许多动词(如ask,allow,invite,teach,tell,等)后都可直接跟动词不定式做宾语补足语

如:I asked him to arrive on Saturday.(我让他星期六来。)He allowed me to come here.(他允许我来这儿。)

2. 某些感官动词(如see,here,watch,feel,notice等)和使役动词(如let,make,have等)后面要跟不带to的动词不定式做宾语补足语

如:I saw him play basketball with Jack an hour ago.(一小时前我看见他和杰克打篮球。)

Let me tell you something about the Olympic Games.(让我告诉你一些关于奥运会的事情。)

注意:含有感官动词和使役动词的句子在变成被动语态时,不定式to要还原,不能省去,因为这时它在句中做主语补足语。

如:The baby was made to cry by the boy.(这个孩子被男孩弄哭了。)

The workers are made to work twelve hours a day.(工人们每天被迫工作12小时。)

3. help后面接动词不定式做宾语补足语时,既可以带to,也可以省略to

如:The Young Pioneers helped Grammy Wang(to)carry water.(少先队员们帮助王奶奶打水。)

He often helps me(to)learn English.(他经常帮助我学习英语。)

五、动词不定式做定语

动词不定式做定语要放在它所修饰的名词或代词之后,常做后置定语。

如:I have some homework to do.(我有一些作业要做。)

She was the only one to get the award.(她是唯一一个获得奖励的人。)

注意:当动词不定式与所修饰的词之间存在逻辑上的动宾关系时,动词不定式的动词要用及物动词或相对于及物动词的动词短语。

如:She has no paper to write on.(她没有写字用的纸。)

That is the only thing to worry about.(那是唯一令人担心的事。)

六、动词不定式做状语

1. 动词come,go,step,hurry后接动词不定式做状语,表示目的

如:He went to see his sister yesterday.(他昨天去看妹妹了。)

They got up early to catch the early bus.(他们起床早是为了赶上早车。)

2. 用于“be+形容词+不定式”结构

如:I was sorry to hear that you were ill.(听说你病了,我很难过。)

七、动词不定式的被动语态

动词不定式的被动语态是由“to be+过去分词”构成。

如:There are twenty trees to be planted.

八、动词不定式的否定结构

动词不定式的否定结构是:not+to+动词原形。在感官动词和使役动词后,to也可省略。

如:I told him not to stand here.(我叫他不要站在这儿。)

篇4:动词不定式省略to的用法总结

不定式省to有六种情况:

一、 在主动结构中,下列动词后作宾补的动词不定式应省略to

“五看”(see, watch, notice, observe, look at)“三使”(make, let, have)“两听”(hear, listen to)“一感觉”(feel)半帮助(help)

如:Who made him work all night long?

但是,改为被动结构后,应补出省略的to。

如:He was seen to break the window.

二、would rather, had better,Why…,Why not…后

如:You had better stay at home.

Why not have a good rest on Sunday?

三、介词except / but/other than等后遵循“有do略to,无do 补to”

用作介词except, but宾语的不定式有时带to,有时不带to。其大致原则是:若其前出现了动词 do,其后的不定式通常不带 to;若其前没有出现动词 do,则其后的不定式通常带 to。

如:I had no choice but to wait. 除了等,我没有别的选择。

He wanted nothing but to stay there. 他只想留在那儿。

She can do everything except cook. 除了做饭之外她什么都会。

四、主语带do表语省略to的情况

当主语部分有动词do的某种形式时,用作表语的不定式可以省略to。

如:All you do now is (to) complete the form. 你现在要做的只是把这张表填好。

The only thing to do now is (to) go on. 前进是现在唯一的出路。

What I’ll do is (to) tell her the truth. 我要做的就是告诉她真相。

五、并列不定式省略to的情况

当两个或多个作用相同的不定式并列时,通常只需在第一个不定式前用to,其余不定式前的to可以省略。

如:He told me to stay there and wait for him. 他叫我在那儿等他。

I’m really puzzled what to think or say. 我真不知该怎么想怎么说。

It is easier to persuade people than (to) force them. 说服人容易,强迫人难。

但是,如果两者有对比关系,则后面不定式前的to不可省略。

如:To try and fail is better than not to try at all. 尝试而失败总比不尝试好。

六、省略不定式是否保留to

在一定的上下文中,为了避免重复,有时不定式可以省略,但通常保留不定式符号to。

如:I shall go if I want to. 如果我想去就去。

“Don’t be late.” “I’ll try not to.” “不要来晚了。”“我尽量不来晚。”

Don’t go till I tell you to. 等我叫你走你再走。

注意:1>. 若被省略的不定式为to be短语,则通常应保留to be。

如:He is not the man he used to be. 他已不是原来的那个样子了。

2>. 有时省略不定式时,同时也可省略to。

如:She may go if she likes (to). 她想去就可以去。

篇7:动词不定式的用法

I am very glad to hear it.

The question is difficult to answer.

“too + 形容词或副词 + 不定式”作状语。如:

He is too old to do that.

另外,句子中有enough这个词时,常用不定式作状语。例如:

The room is big enough to hold us.

6)作表语。如:

My job is to help the patient.

7)作独立成分。如:

To tell the truth, I don’t agree with you.

8)不定式与疑问词who,which,when,where,how,what等连用,在句中起名词作用,可充当主语、表语、宾语等。如:

He didn’t know what to say. (宾语)

How to solve the problem is very important. (主语)

注意:在与why连用时,只用于why或why not开头的简短疑问句中,后面紧跟的动词不定式不带to。例如:

Why not have a rest ?

9)不定式在句中用主动式还是被动式,多数情况下是容易判断的,但有时的确比较复杂,请注意以下几点:

①不定式修饰的名词或代词和不定式逻辑上构成主谓关系时,不定式往往用主动形式。如:

Have you got a key to unlock the door ?

(A key unlocks the door. )

②不定式和它前面被修饰的名词或代词构成逻辑上的动宾关系,又和该句主语构成逻辑上的主谓关系时,不定式常用主动形式。

I have got a letter to write. (I write letter. )

He needs a room to live in. (He lives in a room. )

I know what to do. (I do what. )

但这句如改为下列形式,不定式就得用被动形式:I know what is to be done.

这是因为what is to be done是宾语从句,从句中的主语what是动词do的动作对象。

③不定式作表语形容词的状语,和句中主语构成逻辑上的动宾关系时,不定式多用主动形式,这是因为人们往往认为形容词后省去了for sb. 。如:

He is hard to talk to. (to talk to him)

The book is difficult to understand. (to understand the book)

④在there be结构中,当说话人考虑的是必须有人去完成某件事时,不定式用主动形式;如果说话人强调的事情本身必须完成,则用被动形式。

There is a lot of work to do. (Somebody has to do the work. )

There is a lot of work to be done. (The work has to be done. )

请注意下面两个句子的含义是不同的:

There is nothing to do. (无事可做,感到十分乏味。)

There is nothing to be done. (某东西坏了,无法使之恢复正常。)

2.不定式的时态

1)不定式的一般形式所表示的动作,通常与谓语的动作(状态)同时(或几乎同时)发生,或是在它之后发生。例如:

I saw him go out.

2)如果谓语表示的动作(情况)发生时,不定式表示的动作正在进行,这时不定式就要用进行式。例如:

He pretended to be reading a book when she went in.

3)如果不定式的动作发生在谓语动词之前,就要用完成式。例如:

I’m sorry to have kept you waiting.

3.不定式的语态

当不定式逻辑上的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形式。如:

He asked to be sent to work in the countryside.

It is possible for our hopes to be realized.

4.不定式符号to的保留问题

有时为了避免重复,可以用to来代替前面的不定式,这种情况常出现下列动词后:expect,prefer,care,mean,forget,want,wish,hope,try以及be glad/happy等后。

如果在省略的不定式结构中含有be,have,have been,这些词要保留。如:

―Are you on holidays ?

―No, but I’d like to be.

―I didn’t tell him the news.

篇9:小议动词不定式用法

关键词:动词不定式;形式;方法

中图分类号:G632 文献标识码:A 文章编号:1002-7661(2012)01-167-01

动词不定式通常有以下几种形式:一般式:to do被动to be done.完成式:to have done.被动式:to have been done,进行式:to be doing,完成进行式:to have been doing。不定式在句中可以充当主语、表语、宾语、定语、同位语、状语、补语等成分。

一、作主语

不定式作主语时直接放在谓语动词之前,谓语动词用第三人称单数。To do more practice is right.但更常见的是用it作形式主语,将真正的主语(动词不定式)置于谓语之后。It is right to do more practice.

二、作表语

不定式作表语通常说明主语的内容。例如:All he wanted was to be left alone.

1、主语不定式与表语不定式呼应,例如:To see is to believe.2、主语是由动词转化或派生而来的名词,如果原动词要求接不定式,则表语也应当用不定式,例如:My wish/hope/idea/plan/purpose/intention is to buy a new car.3、主语为all或what从句,表语可用不定式,例如:All you must do is to water the flowers.4、系动词为含有“似乎”、“看来”或“碰巧”之意的动词,表语可用不定式,基本句型为:Sb+seem/appear/happen to do/to be adj.=It seems(ed)/appears(ed)/happens(ed)that.

三、作宾语

不定式作宾语时,不定式的逻辑主语也是全句的主语。例如:He pretended not to see me when I passed.

1、只能跟动词不定式作宾语的动词 考生应牢记want, wish, hope, agree, afrord,choose,forget,manage, promise, expect等只能跟动词不定式作宾语的动词。

2、一些形容词(包括形容词化的分词)后可接不定式 这种不定式也可以叫做宾语。这样的形容词多是表示感情的,通常有:glad/sorry/sure/able/afraid/anxious/careful/content/determined/easer/foolish/free/inclined/likely/lucky/prepared/quick/ready/slow/willing.句中的不定式与句子主语可是主谓关系,例如:I am very glad to see you.句中的不定式与句子主语也可是动宾关系,例如:Volleyball is very interesting to watch.

3、ask/inform/tell/show/advise+间接宾语+直接宾语(疑问词十不定式)

4、think/consider/regard/believe/feel/make/find/suppose+it(形式宾语)+宾补+(for sb.)+不定式(真正主语)例如:Do you find it difficult to answer the question?

四、作补语

动词不定式作主语补足语时一律带to.①S+be+v-ed+to do。表示动作同时发生。②S+be+v-ed+to have done动词不定式作宾补表示动作发生了(即动作全过程结束了)这类动词包括“四看”:see,watch,notice,observe;“三使役”:let,make,have;“二听”:listen to,hear;“一感觉”:feel。

五、作定语

①它与其修饰的词可能是主谓关系,例如:The next train to arrive was from New York.②它与其修饰的词也可能是动宾关系,如果是不及物,则要用“不定式+相应的介词”的结构,这里的介词一般不可省去。例如:He is looking for a room to live in.当不定式若修饰的名词是time,place,way时,不定式后面的介词习惯上可省去。例如:He had no money and no place to live(in).

六、作同位语

例如:He gave the order to star the attack.又如:He followed the instruction to walk along a certain street where I picked him up.

七、作状语

不定式作状语时,可以表示目的、原因、结果等。

例如:1、we have come to learn from you.(目的)

2、I'm glad to meet you.(原因)

3、He is too young to join the army.(结果)

不定式表示目的时,常可用in order to, so as to换用。

八、不带to的不定式

①在感官动词和使役动词后,不定式作宾补要省略to。②在would rather(would sooner,had rather,hadsooner)…than,rather than等结构的,than之后用省to的不定式。例如:I would rather go than stay;③在以why引导的疑问句中不带to,例如:Why not have a rest?④在cannot but, cannot choose but, cannot help but之后的不定式不带to, 例如:He cannot choose but keep silent. ⑤不定式动词在介词but, except, besides后面时,如果这些介词之前有行为动词do的各种形式,那么这些介词后的不定式不带to,否则要带to。例如:She could do nothing but cry. ⑥为了避免重复,有些不定式可省去。例如:I’m really puzzled what to think or say. ⑦不定式还可用在let fly(投射),make believe(假装)。

九、学习动词不式定需要注意哪些问题?

1、不定式的逻辑主语可以为分以下几种情况:

①与该句子的主语一致。例如:

I came here to attend an important conference.

②该句子的宾语是不定式的逻辑主语。例如:

The lady asked him to bring a cup of coffee for her.

③不定式的逻辑主语有介词of和for引出。例如:

It's very nice of you to lend me so much money.

2、不定式与介词。

介词后面一般不跟动词不定式作其宾语。例如:

不能说:I'll take a rest after to have supper.

应该说:I'll take a rest after(having)supper.

晚饭后,我将休息一下。

篇10:do强调句型的用法

当句子中没有其他的助动词时,我们可以在动词前使用助动词do表示对该动词的强调。如:

Do be careful with that vase!务必小心那个花瓶!

I do hope you’ll stay for lunch.我真的希望你留下吃午饭。

用于表示强调的do可以有时态的.变化,但其后的动词要用原形。如:

He does look tired. 他确实显得很疲倦。

He did come but soon went back.他的确来过,但很快就回去了。

She did write to say thank you.她的确写信向你道谢了。

篇11:初中动词不定式用法讲解

动词不定式是动词的一种非谓语形式,又叫非谓语动词,它没有人称和数的变化,在句子中不能做谓语;它由“to+动词原形”构成,这里的to是动词不定式符号,本身没有词义,其否定形式常在to前加not;由于它仍保持动词的特点,可以有自己的宾语和状语,还可以带疑问词和由for引出其逻辑主语等形成动词不定式短语;不定式或不定式短语具有名词、形容词和副词的特征,在句子中可作主语、表语、宾语、宾语补足语、定语和状语等句子成分。为使同学们更好地掌握其用法,现总结如下:

一、动词不定式作主语

动词不定式作主语时,为避免句子的头重脚轻,常用it作为形式主语,而真正的主语动词不定式后置。如要说明动作的执行者,可在不定式前加for引导的短语;但如果表语是nice, kind, clever等描述动作执行者的性格、品质的形容词时,则应在不定式前加of引导的短语。

常用句型: 1,It +be+adj./n.+(for/of sb.)to do sth.(用of还是for决定于前面的adj, adj若是指sb.的特性,就用of,adj若是指sth的特性就用for)

例句:It’s so nice of you to help me with my homework.你真是太好了,帮助我完成作业。

It’s very difficult for me to do the math homework.数学作业对于我来讲太难了。

2,It takes sb.some time to do sth.例句:It takes my mother all day to do the housework.做家务花了我妈妈一整天的时间。

二、动词不定式作宾语

一些动词,如want, decide, hope, ask, offer, agree, choose, learn, plan, need, teach,prepare等,常接动词不定式作宾语(如want/decide to do sth.等)。当动词不定式作宾语时,如果后接宾语补足语,常用it作形式宾语,而把真正的宾语放在宾语补足语之后。注意:有些动词后面可接不定式作宾语,也可接动名词作宾语,所表达的意义也不同。如:

(1)stop to do sth.停止正在做的事,去做另一件事;

stop doing sth..停止正在做的事

(2)go on to do sth.做完一件事后,继续做另一件事;

go on doing sth.继续做同一件事

(3)remember/forget to do sth.记住/忘记去做某事;(未做)

remember/forget doing sth.记得/忘记做过某事(已做)

三、动词不定式作定语

动词不定式作后置定语时,与被修饰的名词逻辑上有动宾关系。如果动词不定式是不及物动词时,则要带上与之搭配的介词,构成及物动词短语。

如: have/has +某事+to do

eg: I have so many homework to do.我有许多作业要做。

enough+名词+to do

eg: It’s difficult enough to do my math homework.数学作业太难了。

“It’s time to do sth.”

eg: It’s time to go home.是时候回家了。

四、动词不定式作宾语补足语

有些动词,如tell, ask, want, invite, teach, like, call等可接带to的动词不定式作宾语补足语,构成tell/ask/want /call/invite sb.to do sth.结构。应注意动词不定式作使役动词和感官动词的宾语补足语时应省去to,在被动语态中应加上to。这些动词可归纳为“一感(feel),二听(listen to, hear),三让(let, make, have,,四看(look at, see, watch, notice),半帮助(help)(即在动词help后面作宾语补足语时,to可有可无)”。另有口诀帮助记忆:“感使动词真奇怪,to在句中像妖怪,主动句中to离开,被动句中to回来。”(let不用于被动语态)

五、动词不定式作状语

动词不定式作状语主要用来修饰动词,表示目的,结果或原因。为了强调目的,有时可以把动词不定式放在句首,或在不定式前加in order或so as。常用结构有too + adj./adv.+ to do sth.等。

例句:I go to bed early in order to get up early in the next day.我那么早睡觉就是为了第二天能早起。

My little brother is too young to go to school.我的弟弟太小而不能上学。

六、固定句式中动词不定式的用法

在固定句式中对不定式的考察常见的有:

had better(not)do sth.最好做(不做)某事。

Would you like to do sth.?你想要做(不做)某事吗?

Why not do sth.?为什么不做某事?

Would you please(not)do sth.?请您可以做(不做)某事么?

What is American food? At first you might think the answer is easy as pie. To many people, American food means hamburgers, hot dogs, fried chicken and pizza. If you have a sweet tooth, you might even think of apple pie or chocolate chip cookies. Its true that Americans do eat those things. But are those the only kind of vittles(食物) you can find in America?

篇13:英语动词不定式用法详解

【关键词】动词不定式 句法功能 时态语态 否定式 疑问词+不定式 省略

非谓语动词是由动词变来但不能作谓语的动词形式,但可以带自己的宾语或状语,构成非谓语动词短语。不定式是最常用的非谓语动词之一,下面从句法功能、时态和语态等方面举例说明其用法。

一、句法功能

动词不定式具有名词、形容词和副词之特性,同时也保留动词特征,同自己的宾语和状语一起构成不定式短语,在句中作主语、宾语、定语、状语、补语、表语。

1.作主语

To love and to be loved are both happiness.

(1)不定式作主语时,为了避免头重脚轻,常用it作形式主语,不定式作真正主语,常见句型有:

It is very nice to get up early and do morning exercise.

It is a great honor to make a speech at the meeting.

It took me five hours to finish my homework yesterday.

It is against my will to tell her the secret.

(2)不定式的逻辑主语用of或for引出。用for时,它前面的形容词说明不定式的性质,而不是说明逻辑主语,常见的形容词有:important, necessary, difficult等;用of时,常用表示人的品质的形容词,常见形容词有:nice, good, cruel, typical, silly, foolish, stupid, bright, clever, wise, right, wrong, mistaken等,也可以用“逻辑主语+系动词+该形容词”模式改写:

It is very important for us to fasten safety belts.

It was silly of her to believe what he said = She was silly to believe what he said.

2.作宾语

(1)agree, beg, choose, decide, afford, fail, expect, hope, long, offer, manage, plan, prepare, pretend, strive, refuse, intend, promise, seem, wish, want等后常跟不定式作宾语。不定式一般不作介词宾语,但可以作but, except的宾语:

My parents agreed to send me abroad for holidays if I passed the exam.

He had no choice but to have a rest at home.

(2)like, love, hate, continue等动词后跟不定式和动名词作宾语意义接近,区别在于不定式表示具体的动作,动名词表示抽象概念:

I like reading, but I don’t like to read in the classroom today.

(3)不定式作宾语时,用it作形式宾语,常跟一个形容词或者名词作宾补:

We consider it necessary to learn English well in case you go abroad.

We have made it a rule not to watch TV during dinner time.

3.作定语

(1)作定语时,与被修饰词之间有逻辑上的“主谓关系”、“动宾关系”等:

He is always the first to come and the last to go. (主谓关系)

I have a very important meeting to attend this afternoon. (动宾关系)

I will go to Shanghai. Do you have anything to be taken there? (主谓关系)

注:此句中you不是不定式逻辑主语,故anything就成逻辑主语,anything与take之前构成被动关系,故用被动形式,但也可用主动形式:

I will do some washing. Do you have any clothes to wash (to be washed)?

There is a lot of homework to do (to be done) today.

(2)如果作定语的动词不能与被修饰词之间构成动宾关系时,要加相应的介词,构成介宾关系:

I have bought a pen to write with and some paper to write on.

(3)某些抽象名词ability, way, need, possibility, determination等后也跟不定式作定语:

The girl has the ability to operate this modern machine.

He has showed the determination to finish the work ahead of time.

4.作状语

不定式作状语时,通常表示原因、目的和结果,逻辑主语通是句子的主语,有主动和被动之分:

I was very pleased to hear the satisfactory news. (原因)

In order to go to college, I have to learn English well. (目的)

The question is very difficult to answer. =To answer the question is very difficult.

注意:不定式在这种情况下作状语,一般是及物动词,与主语之间是逻辑上的动宾关系,翻译为“…起来”,不用被动式:

The woman is very difficult to deal with.= To deal with the woman is very difficult.

He woke up at midnight, only to find the door was open.(结果)

He hurried to the school, only to be told that in was Sunday. (结果)

注意:分词也可作结果状语,但不定式的主动和被动形式都表示出乎预料的结果,而现在分词和过去分词均表示必然结果:

He was late again and again, thus making the boss angry.

He smoked again at work, thus caught by the boss.

5.作补语

(1)作宾补或主补时,不定式的逻辑主语就是句子的宾语或者主语,有主动和被动之分。常用动词有:advise, allow, ask, beg, cause, consider, desire, encourage, expect, force, get, invite, oblige, order, permit, persuade, prefer, request, teach, tell, want, warn等:

Our school doesn’t permit anyone to smoke in the school campus.(宾补)

We were forced to leave the classroom when school was over. (主补)

(2)动词notice, let, make, hear, listen to, see, look at, watch, observe, have, feel跟省略to的不定式作宾补,但这些动词变为被动语态时,作主补的不定式要加上to:

I noticed a young lady enter the room hurriedly.

A young lady was noticed to enter the room hurriedly.

6.作表语

不定式作表语既可表示将来发生的动作,也可表示应该做某事:

My job is to teach children English after graduation.

Who is to blame for the broken window?

二、动词不定式的时态和语态

不定式不仅有时态的变化,而且有语态的变化。当不定式的逻辑主语是不定式动作的承受者时,就用被动语态。

1.一般式表示动作或状态与谓语动词动作或状态同时发生或之后发生:

He likes to swim in the small river this afternoon.

Nobody likes to be criticized in public.

2.完成式表示动作或状态在谓语动词动作或状态之前发生:

He was lucky to have met a kind and helpful man.

The book is said to have been translated into English.

3.进行式表示动作在谓语动词动作或状态发生时正在发生:

He pretended to be sleeping when his mother told him to do washing.

4.完成进行式表示在谓语动词动作或状态发生之前开始的动作,到谓语动词动作发生时可能停止,也可能会持续下去:

He seems to have been standing there for five hours.

三、动词不定式的否定及其它

1.不定式的否定式是在不定式符号to前面加not:

The teacher ordered us not to make any noise in the classroom.

2.疑问词+不定式

“疑问词+不定式”相当于一个名词,在句中作主语、宾语和表语,其中的不定式常用一般式:

When to start for the journey has not been decided.

If you don’t know when to start for the journey, you’d better call him.

The problem is when to start for the journey.

3.不定式to的省略情况

(1)在had better, would rather…than…, would…rather than…, do nothing but \ except \ other than, might as well, cannot help but \ cannot choose but \ cannot but以及情态动词、助动词之后:

I would rather stay at home than go to the cinema in such terrible weather.

There is nothing I can do other than \ but \ except ask for a leave.

(2)动词help后可直接跟省略to的不定式,即help do sth.;help后的不定式作宾补时,如果句子主语直接参与不定式动作时省略to,句子主语不直接参与不定式动作时,一般不省略to:

Please help do housework, as I am too busy.

Would you please help me carry the box upstairs?

The book will help me to improve my writing skills.

(3)在why 或why not开头、表示建议的疑问句中:

Why argue with your mother?

Why not go outside and breathe some fresh air?

(4)并列的两个以上的不定式,从第二个开始省略to,但对比关系中不能省略:

She will come to help us and give us a lecture.

We haven’t decided whether to go to America or to stay in China during the vacation.

(5)不定式作表语时,系动词前边有动词do的任何形式;句子主语是all或what引导的从句;主语被only, first, one, least及形容词最高级所修饰时:

The first thing I want to do now is (to) thank all the people who have helped me in my life.

All I can do is (to) offer him some money to buy food and clothes.

What she really hopes is (to) marry an honest man.

The only thing he can do is (to) do well in the exam.
