重点解析4 动名词结构作主语

动名词的基本结构

动名词的结构一般有两种形式,即一般式和完成式。

(1)一般式

通常,动名词的一般式所表示的动作与谓语动词所表示的动作同时发生,或发生在谓语动词所表示的动作之后。其主动语态和被动语态分别为: doing being done

· Going to that university for further study is her dream. 去那所大学深造是她的梦想。

· Being punished for no reason makes Tony feel wronged. 无缘无故受到惩罚,这让托尼感到 委屈。

(2)完成式

动名词的完成式所表示的动作,发生在谓语动词所表示的动作之前。其主动语态和被动语态分别为: having done having been done

· Having finished all the housework makes her much relieved. 做完了所有的家务,她感觉如 释重负。

· Having been trained for three months looks as if it had cost her one year. 对她而言,受训练 的三个月就好像过了一年那样漫长。

动名词作主语

动名词作主语常用来表示习惯性、经常性的动作,在口语中也可以表示具体的动作,这时可以与动词不定式互换。

(1)动名词或动名词短语直接位于句首作主语

· Swimming is my father's favorite sport. 游泳是我父亲最爱的运动。

· Taking some exercise is good for your health. 适量运动有益健康。

· Listening to the piano music brings me much enjoyment. 听钢琴曲让我很享受。

· Getting up on time is her habit. 按时起床是她的习惯。

· Traveling around the world is a very fantastic experience. 环游世界是一次非常美妙的经历。

(2)动名词作真正主语,it作形式主语
① 在“ It is + no use / no good / a waste of time...+ 动名词”结构中, it 作形式主语,动名词作真正主语

· It is no use screaming here. They will never show any sympathy for you. 在这大喊大叫 没有用。他们绝不会同情你。

· It is no good crying over split milk. 覆水难收。

· It is really a waste of time waiting for him here without any practical action. 没有任何实际行 动地在这儿等他,这简直是浪费时间。

· It is no use writing to her. She even drops the letters into the trash can. 给她寄信根本没用。 她甚至把信件丢进了垃圾桶里。

· It's a great fun chatting with you. 跟你聊天很有意思。

② 在“ It is + good / nice / interesting / useless / worthwhile... + 动名词”的结构中,

it 作形式主语,动名词作真正主语

· It is nice going for a walk with your sweetheart after supper. 晚饭后,和心爱的人一起散步的 感觉很好。

· It is worthwhile trying a new life style. 尝试一种新的生活方式是很值得的。

· It is good reading a few pages every day. 每天读几页书挺好的。

· It is quite interesting staying with these children. 和这些孩子待在一起真有趣。

(3)动名词在“There be”句型中作主语

这里动名词中的动词多为表示“认知、转述”等意义的词 (如 know say 等) ,其后常跟疑问词 (如 what when where 等) 。

· There is no telling when Rita will return from Italy. 没人说丽塔什么时候会从意大利回来。

· There is no saying when she will leave this place. 很难说她会何时离开这个地方。

· There is no knowing where they shall meet next time. 不知道他们下次会在哪里遇见。

· There is no planning where these idle machines should be placed. 还没想好这些闲置的机器 应该放哪儿。

语法补遗

★在“ there is no + V-ing ”的结构中,也可以灵活地使用其它动词。需要注意的是在 “There be ”句型中只能用动名词,而不能用动词不定式作主语。

· I'm serious. There is no joking about a matter like this. 说真的,像这种事情不是开 玩笑的。

· There is no setting back the wheel of history. 历史的车轮不可阻挡。

· There is no playing dumb in front of me. 不要在我面前装傻。

(4)用于布告形式的缩略结构中

· No fishing! 禁止钓鱼! 相当于 No fishing is allowed here!)

· No smoking! 禁止吸烟! 相当于 No smoking is allowed here!)

· No parking! 禁止停车! 相当于 No parking is permitted here!)

(5)在动名词的复合结构中作主语

通常可以在动名词前面加上一个形容词性物主代词或所有格形式,构成动名词的复合结构。那么,动名词的复合结构就可以在句中作主语,所有格作动名词的逻辑主语。

· Their coming to my first show is a great encouragement to me. 他们来给我的首秀捧场,对 我来说真是极大的鼓舞。

· Mr. Green's quitting from the team was a huge loss for our department. 格林先生的退出对我 们部门来说是个巨大的损失。
