动词ing形式是动词的一种非谓语形式, 包括现在分词和动名词两种, 是由动词原形加ing构成, 此结构既强调动作也具有名词、形容词的性质。在句子中用作主语、表语、宾语、定语、补语和状语。本单元学习动词ing形式作主语。
要点一 动词ing的基本形式
项目
主动语态
被动语态
一般式
doing
being done
完成式
having done
having been done
1.动词ing形式的一般式常表示该动作与句子谓语动作同时发生或发生在谓语动词所表示的动作之后。
For most people, having things stolen feels like an offence.
对大多数人来说, 东西被偷是一种冒犯。
2.动词ing形式的完成式表示该动作发生在主句谓语动作之前。
Having ever travelled to that beautiful city has made him want to travel there again.
曾经去那座美丽的城市旅游(的经历), 使他想再次去那儿旅行。
3.动词ing形式若与其逻辑主语之间为被动关系时, 需用被动语态, 而不及物动词的非谓语形式无被动语态, 但可有完成形式。
Being asked to do so much homework made him unhappy.
被要求做这么多家庭作业使他感到不高兴。
4.动词ing形式的否定形式, 是在其前面加not。
Not knowing how to use a computer makes it more difficult for him to do his academic research.
不知道如何使用电脑, 他更难进行学术研究。
5.动词ing形式的复合结构, ing形式加上自己的逻辑主语, 如形容词性物主代词、名词所有格、人称代词的宾格或名词普通格, 便构成了动词ing形式的复合结构。
His coming made us very inspired.
他的到来让我们深受鼓舞。
Tom's being outspoken won the respect of his fellow workers.
汤姆的坦诚赢得了同事们的尊敬。

要点二 动词ing形式作主语
1.动词ing形式作主语时, 多表示经常性、习惯性的动作, 谓语动词多用单数形式。
Reading aloud is a good way to learn a language.
大声朗读是学习语言的一种好方法。
Having a walk every day helps to make one keep healthy.
每天散步有助于一个人保持(身体)健康。
[名师点津]
意义不同的两个动词ing形式并列作主语时, 谓语动词需用复数形式。
Listening to music and reading are his two hobbies.
听音乐和读书是他的两个爱好。
2.位置
动词ing形式作主语时通常有两种位置:一种是位于句首;另一种是it作形式主语, 而将动词ing形式移至后面。常用动词ing形式作主语的句型:
It is a waste of time doing…(做……是浪费时间的);
It is no good/use doing…(做……是没好处/没用的);
It is worthwhile doing…(做……是值得的);
It is useless doing…(做……没有用);
It is no fun doing…(做……没有乐趣)。
It is no use crying over spilt milk.
