22、nce on the stage. 我看見她在臺上跳舞了。(強調(diào)事實)動名詞的作用(高中)動名詞具有名詞的性質(zhì),因此在句中可以作主語、表語、賓語、定語等。 一 作主語Reading is an art. Climbing mountains is really fun. Working in these conditions is not a pleasure but a suffer. 動名詞作主語,在動詞的基礎上加Ing,是該動詞或動詞短語,有名詞的各種特征,可作名詞靈活使用。 It is no use/no good crying over spilt milk. 覆水難收 It is

24、時,不太常用 it 作先行主語,多見于某些形容詞及名詞之后。 It is no use telling him not to worry. 常見的能用于這種結(jié)構(gòu)的形容詞還有:better,wonderful,enjoyable,interesting,foolish,difficult,useless,senseless,worthwhile,等。 注意:important,essential,necessary 等形容詞不能用于上述結(jié)構(gòu)。 3. 用于“There be”結(jié)構(gòu)中。例如: There is no saying when he'll come.很難說他何時回來。 4. 用于
25、布告形式的省略結(jié)構(gòu)中。例如: No smoking ( =No smoking is allowed (here) ). No parking. (禁止停車 5. 動名詞的復合結(jié)構(gòu)作主語 當動名詞有自己的邏輯主語時,常可以在前面加上一個名詞或代詞的所有格,構(gòu)成動名詞的復合結(jié)構(gòu),動名詞的復合結(jié)構(gòu)也可以在句中作主語。 Their coming to help was a great encouragement to us. 6.例詞 Shopping fishing cycling這些都是很常見的動名詞 (二)、動名詞作主語與動詞不定式作主語的比較 動詞不定式和動名詞都可以用作主語。在意義上相近。
26、但動名詞多用來表示泛指或抽象動作,不定式多用來表示特指或具體動作。比較: Smoking is not good for health. It is not good for you to smoke so much. 注意: 1)在口語中,用動名詞作主語位于句首的較不定式多見。 2)在“It is no use.”,“It is no good.”,“It is fun.”,“It is a waste of time.”等句型中,通常用動名詞作真實主語: It is no use/good/a waste of time talking about that. *It is no use/
27、good/a waste of time to talk about that. 3)在疑問句中,通常用動名詞的復合結(jié)構(gòu),而不用不定式的復合結(jié)構(gòu)作主語: Does your saying that mean anything to him? *Does for you to say that mean anything to him? 4)在“There be”句型中,只能用動名詞,而不能用不定式作主語: There is no telling what will happen. It is impossible to tell what will happen. 5)當句子中的主語和表語都是
28、非限定動詞時,要遵循前后一致的原則,主語和表語在形式上要求統(tǒng)一: Seeing is believing. *To see is to believe. 二 作賓語(1)作動詞的賓語 某些動詞后出現(xiàn)非限定性動詞時只能用動名詞作賓語,不能用不定式。常見的此類動詞有:advise, allow, permit, avoid, consider, enjoy, finish, give up, cannot help, imagine, include, keep, keep on, mind, miss, put off, delay, practise, resist, suggest, dep
29、end on, think about, set about, succeed in, worry about, burst out, insist on, cant stand, escape be used to, get used to, devote to, look forward to, pay attention to, get down to, 等。 They went on walking and never stopped talking. I found it pleasant walking along the seashore. 在海灘上走真是樂事。 Mark oft
30、en attempts to escape being fined whenever he breaks traffic regulations. (2)作介詞的賓語 We are thinking of making a new plan for the next term.Shall we have a rest or get down to doing our work? (3)作形容詞的賓語 The music is well worth listening to more than once.We are busy preparing for the coming sports me
31、et. 三 作表語動名詞作表語時句子主語常是表示無生命的事物的名詞或what引導的名詞性從句。表語動名詞與主語通常是對等的關系,表示主語的內(nèi)容,主語、表語可互換位置。Your task is cleaning the windows. 你的任務就是擦窗戶。(Cleaning the windows is your task.) What I hate most is being laughed at.(Being laughed at is what I hate most.) 四 作定語動名詞作定語往往表示被修飾詞的某種用途。如: a walking stick a stick for wa
32、lking=a stick which is used for walking a washing machine=a machine for washing=a machine which is used for washing a reading room=a room for reading=a room which is used for reading a measuring tape=a tape for measuring=a tape which is used for measuring sleeping pills=pills for sleeping=pills whic
33、h is used for sleeping 五 動名詞的復合結(jié)構(gòu)帶有邏輯主語的動名詞叫動名詞的復合結(jié)構(gòu)。當動名詞邏輯主語與句子主語不一致時,要在動名詞之前加上物主代詞或名詞所有格,這便構(gòu)成了動名詞的復合結(jié)構(gòu)。其中物主代詞(名詞所有格)是邏輯上的主語,動名詞是邏輯上的謂語。動名詞復合結(jié)構(gòu)在句中可作主語、賓語、表語等,分別相當于一個主語從句、賓語從句、表語從句。 Her coming to help encouraged all of us. 他來幫忙鼓舞了我們所有人。 (=That she came to help encouraged all of us.) Janes being care
34、less caused so much trouble. 簡的粗心惹來了不少麻煩。 (=That Jane was careless caused so much trouble.) Whats troubling them is their not having enough food. (=Whats troubling them is that they have not enough food.) 在口語中,如果動名詞復合結(jié)構(gòu)作賓語,其中的物主代詞常用人稱代詞賓格,名詞所有格常用名詞普通格來代替,但在句首作主語時不能這樣來代替。如: Would you mind my/me using
35、 your computer? 用下你的電腦介意嗎? The father insisted on his sons/his son going to college. Marys (不可用Mary) being ill made her mother upset. His (不可用Him)smoking made his family angry. 在下列情況下動名詞的邏輯主語必須用名詞的普通格或人稱代詞賓語: a.無命名詞 The baby was made awake by the door suddenly shutting.b. 有生命名詞但表示泛指意義 Have you ever
36、heard of women practising boxing?c. 兩個以上的有生命名詞并列 Do you remember your parents and me telling about this? 六 動名詞的時態(tài)和語態(tài) 其否定形式是在doing前加上not 1、動名詞一般式表示的動作通常是一般性動作,即不是明確地發(fā)生在過去、現(xiàn)在或?qū)淼膭幼?,或是與謂語動詞所表示的動作同時發(fā)生的動作。如: I hate talking with such people. 我討厭與這樣的人說話。 Being careless is not a good habit. 粗心不是一個好習慣。 2、動名詞
37、的完成式表示的動作發(fā)生在謂語動詞動作之前。如: I dont remember having met him before. 我記不得以前見過他。 Thank you for having taking so much trouble to help. 謝謝你費力幫忙。 3、動名詞的邏輯主語同時也是動名詞動作的承受者,動名詞用被動語態(tài)。 (1)它的一般式表示的動作與謂語動詞動作同時發(fā)生,或在其前發(fā)生。如: I dont like being laughed at in public.(2)它的完成式表示的動作發(fā)生在謂語動詞之前。如: I am very pleased at your having been honoured with a medal.(3)在某些動詞,我們常用動名詞的一般式表示完成式,盡管動作發(fā)生在謂語動詞動作之前,這似
