1、英语语法专项复习与训练,动 名词By 熊伟,一、动名词的形式,二、功能及用法,1动名词（短语）做主语，如：Writing the book has taken up all his spare time.Seeing is believing.,注：动名词（短语）做主语还常用于下列结构：a.Its no use sending him over.Its too late already.Its no good talking a lot without doing anything.Its a waste of time arguing about it.b.Theres no joking

2、about such matters.Theres no saying what hell be doing next.Theres no telling what hes going to do.,注：动名词作主语与不定式作主语的区别：动名词作主语通常表示抽象的或泛指的动作，一般不与特定的动作执行者联系在一起；不定式作主语通常表示具体的动作或行为，往往与特定的动作执行者联系在一起，如：Its no use crying over spilt milk.(抽象)He realized that to go on like this was no use.(具体)在实际运用中，一般可以互换，差异

3、不大。但在下列几种情况中不能互换：a.当表语是动名词时，主语也要用动名词；当表语是不定式时，主语也要用不定式，如：Seeing is believing.To see is to believe.,b.动名词和不定式作主语，一般都可以使用形式主语it，而将动名词或不定式放在句尾。但是在下列句型中，一般宜用动名词，不宜用不定式来代替：Its no use doing Its no good doing Its a waste of time doing,例如：Its no use going there today;he wont be at home.Its a waste of time a

4、rguing about it.Its no good waiting here.Lets walk home.,而在Its important/Its necessary/Its advisable/Its essential/Its fitting 这类句型中，只能用不定式，如：Its important to learn foreign languages.Its quite necessary to read it many times.,2动名词（短语）作表语，如：Their job is building houses.His job is raising pigs.注：动名词作表

5、语与不定式作表语的区别：动名词作表语时表示比较抽象的一般行为、习惯；不定式作表语时表示具体的某一次动作，特别是将来的动作，试比较：My favourite sport is swimming.The first thing for us to do is to improve our pronunciation.,注：动名词作表语与现在分词作表语的区别：动名词作表语时相当于名词，说明主语的含义及内容，它与主语是同等关系，主语与表语互换位置不影响句子的基本含义，但不可用副词来修饰。现在分词作表语时相当于形容词，说明主语的特征、性质、状态等，主语与表语不可互换位置，但可用very,quite等副词

6、来修饰，如：My job is looking after the children.Our duty is serving the people heart and soul.The situation is encouraging.This cake is very inviting.The volleyball match we watched was very exciting.,3动名词（短语）用作宾语的情况很多，如：Hearing the words,she couldnt help thinking of her past bitterness.We all avoided me

7、ntioning that matter.能用动名词作宾语的动词有两类：一类是只能用动名词作宾语的动词，其中有：avoid,admit,consider,delay,advise,dislike,enjoy,escape,excuse,finish,give up,cant help,imagine,keep(on),dont mind,miss,practise,put off,stop,go on,resist,suggest等，如：Mary is considering changing her job.I enjoy working with you.Would you mind ri

8、nging me up tomorrow?另一类是既可以用动名词，又可以用不定式作宾语的动词，其中有：begin,cannot bear,continue,forget,hate,intend,like,love,plan,prefer,propose,regret,remember,start,try,want,need,cant afford等。,上述动词尽管可以带两种结构作宾语，但用法不尽相同，需要注意下列几个情况：A.在begin,start,cease,continue,cannot bear,hate,like,love,prefer,propose 等动词后，两种结构意义无大的出

9、入，如：She cant bear being laughed at/to be laughed at.但是在下列情况下，通常用不定式：a.在would like/love/prefer/hate 后表示一个特定的新动作时：Id like to buy a suit.Id hate to disappoint them.b.当谓语动词已用进行时态时：The water is beginning/starting to boil.Im starting to work on my essay next week.c.在begin 等后，非限定动词由某些状态动词构成时（即：指心理状态或精神活动时）

10、：She began to believe his story.He began to realize that he was wrong.d.当主语是物，不是人时：The water started/began to boil.The ice started/began to melt.,B.在need,want,deserve等后，可用动名词的主动式表示被动含义，或用不定式的被动式，意义上无差别。但用动名词较为普遍，（这时主语一般是物），如：The door needs oiling/to be oiled.C.有的动词尽管可以用两种结构，但意义明显不同，须认真加以区别：I forgot

11、to close the door before I left the room.I forgot having closed the door.He tried to write better.(尽量努力地写)He tried writing with a brush.(用毛笔试着写)I couldnt help finishing it.(不能不结束某事)I couldnt help to finish it.(不能帮助结束某事)They left off fishing.(停止钓鱼)They left off to fish.(离开某处出发去钓鱼)I regret to say that

12、 there is no wine in the bottle.(对现在要发生的事表示遗憾、抱歉)I regret not taking your advice.(后悔),动名词（短语）还常常跟在短语动词之后，作介词的宾语。常见的有：insist on/think of/dream of/object to/hear of/prevent from/keep from/stop from/feel like/be engaged in/look forward to/depend on/thank for/excuse for/devote to/set about/spend in/get(

13、be)used to/be fond of/be afraid of/be tired of/succeed in/be interested in/be proud of/burst out/give up 等，如：He insisted on seeing us home.They all objected to putting the meeting off.Are you interested in going to the show?Im thinking of going to town this afternoon.I dont feel like eating anything

14、.She is afraid of falling behind the others.He finally got tired of doing office work.She devotes hours to helping Mother with housework on Sunday.,4动名词（短语）可以和about,against,at,before,after,by,for,besides,from,in,on,upon,without等介词构成短语，在句中作状语，如：They broke in loud cheers on hearing the news.He warned

15、me against swimming there.She left without saying good-bye to us.Besides cooking and sewing,she had to take care of the children.He felt uncomfortable about accepting the gift.They were surprised at your doing that.5动名词（短语）可以和介词构成短语作定语，如：He hasnt much experience in running factories.Whats their reas

16、on for cancelling the English evening?Have you any objection to going there on foot?He has little hope of passing his examinations.They dont approve of his way of looking at things.Im glad to have this opportunity of coming to visit your country.,6动名词还可以作定语，如：singing competition swimming pool dining

17、 car opening speech drinking cup living room typing paper waiting room writing desk washing machine frying-pan sleeping-pill walking stick teaching method注：动名词作定语表示被修饰名词的用途，它和名词之间没有逻辑上的主谓关系；而现在分词作定语，表示被修饰名词本身的动作、行为，它和名词之间有逻辑上的主谓关系。,三、动名词的复合结构,动名词的复合结构就是前面带有代词或名词的动名词结构。有时为了明确动名词所表示的动作的执行者，可以在动名词之前加上一

18、个物主代词或名词所有格，来表示动名词逻辑上的主语。有时也可以用人称代词宾格或名词普通格，不过，这主要用于口语中。如：She wont hear of us leaving the village.Do you object to Li Pings joining the physics group?注：如果不是在句子的开头，这个结构常用名词的普通格或人称代词宾格，如：I dont like the idea of us/our not helping at all.I dont mind Jane buying another one.注：如果动名词的逻辑主语是表示无生命的东西的名词，或不定代

19、词，就只能用普通格，不能用所有格，如：Is there any hope of your team winning the match?The boy was alarmed by someone knocking at the door.,动名词的复合结构有下列用法：作主语：Their coming to help was a great encouragement to us.Nothing is worse than our bowing before difficulties.Lao Lis(not:Li)going wont be of much help.作表语：Our sole

20、worry is your relying too much on yourself.Whats troubling them is their not having enough machine tools.作宾语：Do you mind my reading your paper?Please excuse my interrupting you.作介词宾语：They insisted on my staying there for supper.Do you think there will be any chance of my seeing him again?,四、动名词的完成形式

21、与被动形式,动名词的一般形式通常表示一般性动作（即不是明确地在过去、现在或将来发生的动作）或是与谓语所表示的动作同时发生的动作，如：They are all interested in climbing mountains.He took a great delight in helping others.如果要表示动名词代表的动作在谓语所表示的动作之前发生，通常用动名词的完成形式，如：He didnt mention having met me.I regret not having taken her advice.I dont remember having ever promised

22、you that.注：在某些动词之后（或在成语中）常用（或可以用）动名词的一般形式表示在谓语动作之前发生的动作，如：Excuse me for coming late.I dont remember ever seeing him anywhere.,当一个动名词逻辑上的主语所表示的是这动作的承受者时，这个动名词一般要用被动形式，如：This question is far from being settled.He did it without being asked.They insisted on their being treated as ordinary workers.He didnt mind being left at home.They couldnt stand being treated like that.注：如果表示的动作在谓语表示的动作之前发生，有时需要用动名词的完成被动形式，如：I dont remember having ever been given a chance to try this method.,
