动词不定式和动名词作主语的区别

⒊动词不定式和动名词作主语的区别①不定式作主语经常表示具体动作,常与特定的动作执行者联系在一起;而动名词作主语经常表示抽象动作,经常不与特定的动作执行者联系在一起.如:It's no good eating too much fat.It's no good for you to eat so much fat.②动名词结构作主语,可以用名词或代词属格形式作逻辑主语.如:It's no use your pretending that you didn't know the rules.,作宾语⒈不定式作宾语①以下动词后,只能跟不定式作宾语.如:agree, ask, aim, arrange, choose, decide, demand, expect, fail , help, hope, lean, long, manage, offer, plan, prepare, pretend, promise, refuse, wish等,这些词大部分可接that引导的从句.如:I decided to ask for my money back.I decided that I would ask for my money back.When our visit to the farm was over, we expected to start back on foot.When our visit to the farm was over, we expected that we would start back on foot.②当复合宾语中的宾语是不定式时,先用形式宾语it代替不定式,把不定式置于补语之后,即:主语+动词+it+补语+to do句式.如:We think it quite important for us to learn a foreign language well.He feels it his duty to help the poor.③介词but, except, besides +to do(do)在这种句型中,如介词前有动词do,后面应接不带to的不定式;如无do,则接to不定式,即带do不带to, 带to不带do.如:The enemy soldiers had no choice but to give in.On Sunday afternoon I had nothing to do but watch TV.⒉动名词作宾语①以下动词后,只能接动名词作宾语,如:admit, appreciate, consider, delay, enjoy, finish, keep, imagine, mind, miss, practise, resist, risk, save, suggest, don't mind, give up, insist, on, put off等.如:I suggest spending our summer vacation in a seaside town.You must give up smoking, for it does too much harm to your health.②动名词作介词的宾语I should go to attend the birthday celebration instead of staying at home.What about inviting Li Jun to make a speech动名词前的介词有时可以省略,如:have difficulty(in)doing, have no trouble(in)doing, lose no ti me(in)doing, prevent/stop…(from)doing, there is no use(in)doing等.⒊部分动词后面,既可接动词不定式,也可接动名词作宾语,意义不变.如:begin, continue, start, hat e, like, love, need, require, want等.在need, require, want后接-ing形式,表示被动意义,也可接不定式,但要用被动形式,如:Your handwriting needs improving (to be improved). hate, love, like接不定式表示特定的未来事件,接动名词表示目前正在进行的活动或一般的行为.在下列情况下,一般要用不定式:①hate, like, love前有would(should)时,如:I'd like to have a cup of coffee.②当谓语动词begin, continue, start等是进行式时,如:The students are starting to work on the difficult maths problem.③begin, continue, start与know, understand等状态动词连用时,如:I soon began to understand whatwas happening.⒋advise, allow, encourage, forbid, permit等动词后接动名词作宾语,或带不定式作宾语补足语.如:Our teachers don't permit our swimming in the lake.Our teachers don't permit us to swim in the lake.⒌部分动词后接不定式或动名词时,意义差别较大,应根据句子语境选择使用.①forget, remember, regret后接不定式,表示现在或未来的动作,接动名词表示动作已经发生.如:Don't forget fo post the letter for me.Have you forgotten meeting her in Beijing AirportRemember to close the windows before you leave.I remember writing him a letter a year ago.We regret to tell you that all of you are not invited to attend the meeting.They regretted ordering these books from abroad.②mean to do 打算做某事doing 意味着……I meant to catch up with the early bus.This means wasting a lot of money.③try to do 设法尽力做某事doing 试着做某事You should try to overcome your shortcomings.Try working out the physics problem in another way.④stop to do 停下一件事去做另一件事(不定式作目的状语)doing 停止做某事On the way to the airport, I stopped to buy a paper.You'd better stop arguing and do as you are told.⑤can't help doing 禁不住……to do不能帮助干……They couldn't help jumping up at the news.Sorry I have lots of work to do.

such…as toI'm not so stupid(a fool) as to put it in writing.我不至于愚蠢到会把它写下来.I'm not such a stupid fool as to put it in writing.②enough…toThe speed is high enough for us to catch up with the first liner.③only toJane hurried back only to find her mother dying in the hospital.④too…toI'm too tired to stay up longer.但在下列结构中,too…to并非是"太……而不能……"之意.如:①I'm only too glad to have passed the exam.考试及格我太高兴了.(too修饰glad to have…,相当于very)②We have too much to learn.我们要学的太多了(不定式作定语).⒊不定式短语还可作独立成分,用于句首,句中或句末.如:To tell the truth, the play was a great disappointment tome.常见的短语有to be exact(确切地说),to begin with(首先),to do him justice(说句对他公道的话),to be sure(真的)等等.七,动词不定式,动名词的其它用法⒈疑问词+不定式结构疑问词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.②Mr. Smith didn't know whether to leave or stay there.③I asked Professor Xu how to learn English well.④The question was where to get the medicine needed.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 shall leave…③…how I could 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.⒉动词不定式的时态,语态(1)时态①一般式:动词不定式一般式表示的动作发生在谓语动词之后,有时表示同时发生.如:I hope to become a university student this year.(to become发生在hope之后)We often hear Dick play the piano in the next room.(play和hear同时发生)②完成式:表示的动作发生在谓语动词所表示的动作之前.如:I'm sorry to have kept you waiting.We are too young to have seen the old society.③进行式:表示的动作与谓语动词同时发生.如:The teacher happened to be correcting our papers when I came in.They seemed to be discussing something important.(2)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)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)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:These is nothing to do now.( We have nothing to do now.) There is nothing to be done now.(We can do nothing now.)⒊动名词的时态,语态(1)时态①一般式:动名词的一般式所表示的动作可以是泛指,也可与谓语动词同时发生,或发生在谓语动作之前,之后.如:We are interested in collecting stamps.I shall never forget seeing the Great Wall for the first time.We are not afraid of dying.②完成式所表示的动作发生在谓语动词之前.如:Imagine having travelled on the moon.We were praised for having finished the work ahead of time.(2)被动语态①如果动名词的逻辑主语为动名词所表示的动作的承受者,动名词要用被动语态,动名词的被动语态有一般式与完成式之分.如:The young man came in without being noticed.He prided himself on having never been beaten in class.②有些动词后的动名词用主动形式,但表示被动意义.如:The bike needs repairing.If a thing is worth doing, it is worth doing well.⒋在口语中,为避免重复,常用"to"代替不定式结构,有时甚至可以把to省略.如:①-Did you go to visit the Great Wall-No, I wanted to, but there wasn't enough time.②-Would you like to come to a party-I'd love to.③-Don't make any mistakes in your homework, will you-I'll try not to.④-Try to be back by 12, won't you-OK, I'll try.另外,be going to, ought to, used to等也常用于这一结构中.⒌在why引起的问句中,省略"to".如:Why spend such a lot of moneyWhy not wait for a couple of days⒍当两个或更多作用相同的不定式并列使用时,只在第一个不定式前加"to".如:It's quite necessary for us to read more and have more practice.⒎"to"在下列短语中是"介词",后接动名词或名词形式.如:devote…to, face up to(勇敢地面对),look forward to(盼望),object to(反对),take to(养成习惯,对……感兴趣;开始从事某种活动),be used to(习惯于)等.。
