19、吧首先，為大家介紹一個動名詞用法口訣：動名詞常泛指，句法作用賓/表/定與主，時態(tài)/語態(tài)之形式，一般/完成/被動式。being done 系被動，不含任何進(jìn)行意。用作主語請留意，常用it作形式主語，不指未來發(fā)生事，表達(dá)的信息系已知。用作表語請記清，作用相當(dāng)一名詞，檢驗方法很簡單，主與表換位能成立。用作定語也易辯，表示名詞之用途。用作賓語稍復(fù)雜，關(guān)鍵留意謂語動詞(跟動名詞作賓語的常用動詞附后)，時態(tài)同謂動作比較，先于謂動用完成式，其邏輯主語不固定，在句中/句外均有之。否定式其前加not，復(fù)合式其前加物主詞，非句首賓格詞也可用，尤其口語中更如此。說明：1、主-主語 2、賓-賓語 3、表-表語 4、定

20、-定語 5、謂動-謂語動詞動名詞的用法：一、動名詞作主語1. 直接位于句首做主語。例如：swimming is a good sport in summer.2. 用 it 作形式主語，把動名詞(真實主語)置于句尾作后置主語。動名詞做主語時，不太常用 it 作先行主語，多見于某些形容詞及名詞之后。例如：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：im

21、portant，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 hell come.很難說他何時回來。4. 用于布告形式的省略結(jié)構(gòu)中。例如：no smoking ( =no smoking is allowed (here) ). (禁止吸煙)no parking. (禁止停車)5. 動名詞的復(fù)合結(jié)構(gòu)作主語當(dāng)動名詞有自己的邏輯主語時，?？梢栽谇懊婕由弦粋€名詞或代詞的所有格，構(gòu)成動名詞的復(fù)合結(jié)構(gòu)(這時，名詞或代詞的所有格做動名詞的邏輯主語)。動名詞的復(fù)合結(jié)構(gòu)也可以在句中作主語。例如：th

22、eir coming to help was a great encouragement to us.二、動名詞作賓語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：admit, appreciate, excuse, stand, advise, allow, permit, avoid, consider, enjoy, finishthey went on walking and never stopped talking.他們繼續(xù)走，說個不停。i found it pleasant walking along the seashore.在

23、海灘上走真是樂事。mark often attempts to escape being fined whenever he breaks traffic regulations.每當(dāng)馬克違反交通規(guī)則時，他常常企圖逃避罰款的處分。2.作介詞的賓語we are thinking of making a new plan for the next term. 我們正考慮為下學(xué)期制定新的計劃。shall we have a rest or get down to doing our work? 我們休息呢還是開始干活?3.作形容詞的賓語the music is well worth listenin

24、g to more than once. 這種曲子很值得多聽幾遍。we are busy preparing for the coming sports meet. 我們正為馬上到來的運動會忙著做準(zhǔn)備。三、動名詞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(dǎo)的名詞性從句。表語、動名詞與主語通常是對等的關(guān)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(wù)就是擦窗戶。(cleaning the windows is your task.)what i hate most is being laughed a

25、t. 我最痛恨的就是被別人嘲笑。(being laughed at is what i hate most.)四、動名詞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 walking=a stick which is used for walkinga washing machine=a machine for washing=a machine which is used for washinga reading room=a room for reading=a room which is used for readinga me

26、asuring tape=a tape for measuring=a tape which is used for measuringsleeping pills=pills for sleeping=pills which is used for sleeping動名詞是非限定動詞的一種形式，由動詞原形+ing構(gòu)成。它既有動詞的特征，又有名詞的特征，故稱。動名詞也有時態(tài)和語態(tài)的變化，如表所示(以及物動詞write為例)，不及物動詞沒有語態(tài)的變化。時態(tài)、語態(tài)主動被動一般式writingbeing written完成式having writtenhaving been written動名詞使用

27、注意事項：1) 動名詞做主語時，謂語動詞為單數(shù)2) 在動名詞和不定式中，作為介詞的賓語是動名詞3) 動名詞的否定直接在其前加否定詞，通過代詞的賓格或所有格形式給出邏輯主語例：i would appreciate you calling back this afternoon.4) 有些詞后只能接動名詞acknowledge;admit; advise;advocate;allow;appreciate; avoid; celebrate; consider; contemplate; defer; delay; deny;detest; discontinue; dislike; dispute; enjoy; it entails; escape; excuse; explain; fancy; feel l
