IV.Readyusedmaterialsforthe-ingformastheSubject&Object)

語法學習—動名詞

1.動名詞作主語

1)名詞直接放在句首作主語。例如：

Usingtherighthandtoshakehandsisaconventioninmanycountries.

用右手握手是許多國家的一種習俗。

2)動名詞在“Itisnouse/nogood/fun/awasteoftime/agoodpleasure等名詞+

doing”結(jié)構(gòu)中作主語，it為形式主語。例如：

Itisnogoodwritingtohim;heneveranswersletters.

寫信給他不妥，他從來不回信。

Itisnouseyourcomplaining;thecompanywon'tdoanythingaboutit.

抱怨是沒有用的，公司是不會管的。

3)動名詞在"Itisuseless/nice/good/interesting/worthwhile等形容詞+doing"

結(jié)構(gòu)中作主語。例如：

Itisgoodplayingchessaftersupper.

晚飯后弈棋挺好。

Itisuselessspeaking.

光說是沒有用的。

4)動名詞在"Thereis(was)no+doing”結(jié)構(gòu)中作主語。例如：

Thereisnodenyingthatsheisveryefficient.

她效率高是不容否認的。

Thereisnotellingwhatheisgoingtodo.

他要做什么一點消息都沒有。

2.動名詞作賓語

1)有些動詞后面要求跟動名詞作賓語。常這樣用的動詞有：

admit承認；excuse原諒；postpone拖延；anticipate期望；fancy想象

practise練習；appreciate欣賞；finish完成；prevent防止；avoid避免；

forbid禁止；propose建議；consider考慮；forgive寬??；recollect回憶；

delay耽擱；imagine想象；resent厭惡；deny否認；involve涉及；

resist抵制；detest厭惡；keep保留；risk冒險；dislike討厭；mind在意;

save挽救；dread害怕；miss錯過；suggest建議；enjoy喜歡；pardon原諒;

understand理解；escape逃避；permit允許

例如：

Irecommendbuyingthedictionary.

我建議買這本詞典。

Idon'tanticipatemeetinganyopposition.

我估計不會遇到任何反對意見。

Willyouadmithavingbrokenthewindow?

你承認不承認打破了窗戶？

2)有些動詞短語后也要求跟動名詞作賓語。常這樣用的動詞短語有：

can9tstand忍不??；can9thelp忍不??；feellike想，欲；

giveup放棄；putoff推遲

例如：

Heputoffmakingadecisiontillhehadmoreinformation.

在獲得詳情之前，他沒有急于作出決定。

Doyoufeelliketakingawalk?

你要不要去散步？

3)動名詞常跟在介詞或介詞短語后做賓語。常這樣用的介詞短語有：insteadof,

lookforwardto,objectto,keepon,seeabout,taketo等。

例如：

WearelookingforwardtocomingtoChina.

我們期待著來中國。

Wesucceededingettingoverallthedifficulties.

我們終于克服了所有的困難。

4)在“havedifficulty(trouble,problem,ahardtime,fun,agoodtime)(+in)+動名

詞；bebusy(in)+動名詞；wastetime(in)+動名詞；losttime(in)+動名詞；

Thereisnopoint(in)+動名詞”等結(jié)構(gòu)中，動名詞做介詞賓語，in常要省去。例

如：

Thechildrenarebusydoingtheirhomework.

孩子們忙于做作業(yè)。

Thereisnopoint(in)makingthesimpleexperimentsonceagain.

再做一次這種簡單的實驗是毫無意義的。

5)在復(fù)合賓語中，用it作形式賓語，將動名詞短語放在后面。例如：

Iconsideritawasteoftimearguingaboutit.

我認為辯論這事是很浪費時間的。

6)在“therebe”結(jié)構(gòu)當中，be為動名詞時，該結(jié)構(gòu)也是一種帶邏輯主語的動名

詞形式。例如：

Wecanimaginetherebeingalotoffussaboutit.

我們可以想象到人們對此大驚小怪。

Wereyoudisappointedattherenothavingbeenmoregifts?

你對沒有更多的禮物感到失望嗎？

3.動名詞的被動式

1)動詞need,require,want,deserve后，用動名詞的主動形式表示被動意義。其

用法相當于不定式的被動結(jié)構(gòu)。例如：

Thewatchneedsrepairing.(=Thewatchneedstoberepaired.)

這塊表需要修理。

Theproblemdeservesthinkingabout.(二Theproblemdeserverstobethoughtabout.)

這個問題值得考慮。

2)在(be)worth后面只能用動名詞的主動態(tài)來表示被動意義。例如：

Hissuggestionisworthconsidering.

他的提議值得考慮。
