2) 动名词仍然保持着一些动词的性质,所以后面可以接宾语或副词性修饰语。 如play mah-jong, spend money
3) 动名词作主语时,谓语动词用单数形式。
4)动名词既可作动词宾语,又可作介词宾语。如句2 和句4时态和语态1.We are interested in _____ (play) chess2.He was afraid of _____ (leave) at home.4.The house showed no sign of _____ (damage)3.I’m sorry for not _____ (keep) my promise动名词的时态和语态1)动名词的时态:一般式和完成式2)动名词的语态playing being left having kept having been damageddoing ? being done

A. Understanding
B. To be understood
C. Being understood
D. Having understood【答案】A
【解析】本题考察的是非谓语动词中的动名词做主语的用法。本句中的动名词定语understanding your own needs and styles of communication在句中是主语,单个的非谓语动词做主语,谓语动词要使用单数形式。句义:理解你自己的需要和交流方式和知道表达你的爱和情绪一样重要。本句不存在被动关系,排除BC项。D项是现在分词的完成式,表示的是已经完成的动作,与句义不相符。故A正确。3. _____ basic first-aid techniques will help you respond quickly to emergencies. (2013 福建 卷)
A. Known B. Having known
C. Knowing D. Being known
答案:C
解析 : will help 是句子的谓语部分, _____ basic first-aid techniques 是句子的主语部分,起逻辑主语是 you,与 Known 构成主动关系,所以用动词 -ing 做主语。 D 是被动关系。 4. It’s no use _____ without taking action.
(2011上海)
A. complain B. complaining
C. being complained
D. to be complained
答案:B
解析:考查非谓语动词。句意为:光抱怨而不采取任何行动是没用的。根据句型It’s no use doing sth.“做某事没有意义”, 可知选B。5. Listening to loud music at rock concerts ____ caused hearing loss in some teenagers. (2010 湖南卷)
A. is B. are C. has D. have
答案:C
解析:根据动名词短语作主语,句子的谓语动词用单数形式,由此排除B、D两项,根据主语与caused的主动关系,排除A项。
