语法学习—动名词

1.动名词作主语

1)名词直接放在句首作主语。例如：

Usingtherighthandtoshakehandsisaconventioninmanycountries.

用右手握手是许多国家的一种习俗。

2)动名词在“Itisnouse/nogood/fun/awasteoftime/agoodpleasure等名词+

doing”结构中作主语，it为形式主语。例如：

Itisnogoodwritingtohim;heneveranswersletters.

写信给他不妥，他从来不回信。

Itisnouseyourcomplaining;thecompanywon'tdoanythingaboutit.

抱怨是没有用的，公司是不会管的。

3)动名词在"Itisuseless/nice/good/interesting/worthwhile等形容词+doing"

结构中作主语。例如：

Itisgoodplayingchessaftersupper.

晚饭后弈棋挺好。

Itisuselessspeaking.

光说是没有用的。

4)动名词在"Thereis(was)no+doing”结构中作主语。例如：

Thereisnodenyingthatsheisveryefficient.

她效率高是不容否认的。

Thereisnotellingwhatheisgoingtodo.

他要做什么一点消息都没有。

2.动名词作宾语

1)有些动词后面要求跟动名词作宾语。常这样用的动词有：

admit承认；excuse原谅；postpone拖延；anticipate期望；fancy想象

practise练习；appreciate欣赏；finish完成；prevent防止；avoid避免；

forbid禁止；propose建议；consider考虑；forgive宽恕；recollect回忆；

delay耽搁；imagine想象；resent厌恶；deny否认；involve涉及；

resist抵制；detest厌恶；keep保留；risk冒险；dislike讨厌；mind在意;

save挽救；dread害怕；miss错过；suggest建议；enjoy喜欢；pardon原谅;

understand理解；escape逃避；permit允许

例如：

Irecommendbuyingthedictionary.

我建议买这本词典。

Idon'tanticipatemeetinganyopposition.

我估计不会遇到任何反对意见。

Willyouadmithavingbrokenthewindow?

你承认不承认打破了窗户？

2)有些动词短语后也要求跟动名词作宾语。常这样用的动词短语有：

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

giveup放弃；putoff推迟

例如：

Heputoffmakingadecisiontillhehadmoreinformation.

在获得详情之前，他没有急于作出决定。

Doyoufeelliketakingawalk?

你要不要去散步？

3)动名词常跟在介词或介词短语后做宾语。常这样用的介词短语有：insteadof,

lookforwardto,objectto,keepon,seeabout,taketo等。

例如：

WearelookingforwardtocomingtoChina.

我们期待着来中国。

Wesucceededingettingoverallthedifficulties.

我们终于克服了所有的困难。

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

词；bebusy(in)+动名词；wastetime(in)+动名词；losttime(in)+动名词；

Thereisnopoint(in)+动名词”等结构中，动名词做介词宾语，in常要省去。例

如：

Thechildrenarebusydoingtheirhomework.

孩子们忙于做作业。

Thereisnopoint(in)makingthesimpleexperimentsonceagain.

再做一次这种简单的实验是毫无意义的。

5)在复合宾语中，用it作形式宾语，将动名词短语放在后面。例如：

Iconsideritawasteoftimearguingaboutit.

我认为辩论这事是很浪费时间的。

6)在“therebe”结构当中，be为动名词时，该结构也是一种带逻辑主语的动名

词形式。例如：

Wecanimaginetherebeingalotoffussaboutit.

我们可以想象到人们对此大惊小怪。

Wereyoudisappointedattherenothavingbeenmoregifts?

你对没有更多的礼物感到失望吗？

3.动名词的被动式

1)动词need,require,want,deserve后，用动名词的主动形式表示被动意义。其

用法相当于不定式的被动结构。例如：

Thewatchneedsrepairing.(=Thewatchneedstoberepaired.)

这块表需要修理。

Theproblemdeservesthinkingabout.(二Theproblemdeserverstobethoughtabout.)

这个问题值得考虑。

2)在(be)worth后面只能用动名词的主动态来表示被动意义。例如：

Hissuggestionisworthconsidering.

他的提议值得考虑。
