第十三章 动词-ing形式
思维导图
知识梳理
一、动名词的定义
动词-ing形式分为两类:动名词和现在分词.动名词在句中起名词作用,现在分词在句中起形容词或副词作用.
动名词是一种动词的非谓语形式,它兼有动词和名词的特征,由动词原形加词尾-ing而成,其构成法与现在分词一样.动名词有时态和语态的变化.(以do为例)
主动语态 被动语态
一般式 doing being done
完成式 having done having been done
二、动词-ing 形式的句法作用
从性质上讲,动词的-ing形式相当于名词、形容词、副词.因此,它在句中可用作主语、表语、定语、宾语、状语和宾语补足语.
(一)作主语
动词-ing形式作主语通常表示一种抽象的动作概念,即泛指某种行为或动作.
Eating too much is bad for your health.吃得太多对身体健康有害.
Is playing basketball after lunch good or bad for your health 吃完午饭就打篮球对身体健康有益还是有害
Travelling abroad can widen one's outlook.出国旅行会扩大人们的视野.
点拨
(1)动词-ing形式短语作主语,通常有两种位置:一是放在句首,如上述例句所示;一是用it作形式主语,而将-ing分词短语移到谓语部分之后,以避免句子结构头重脚轻.
Having his brother here will make him happier.
It will make him happier having his brother here.
让他的兄弟待在这里将会使他高兴一些.
Swimming in this river is dangerous.
It is dangerous swimming in this river.在这条河中游泳很危险.
(2)动词-ing形式作主语还可以用于“There is no+-ing形式”(····是不可能的)结构.
There is no smoking here.这里不许吸烟.
There is no joking about such matters.这件事开不得玩笑.
(二)作表语
动词-ing形式(短语)作表语有时起名词作用,泛指动作,有时起形容词作用,指主语的性质、状态.
His hobby is collecting stamps.他的爱好是集邮.
The news is exciting.这消息令人兴奋.
The food smells inviting.这道菜香味怡人.
My favourite sport is playing table tennis.我最喜欢的运动是乒乓球.
The only thing she is interested in is dancing.她唯一感兴趣的就是跳舞.
点拨
不要把作表语的-ing形式与进行时态相混淆.-ing形式作表语表示主语的某种特征,而进行时态则表示正在进行的动作.试比较:
Her job is teaching.她的工作是教书.(teaching是表语)
She is teaching there now.她正在那儿上课.(is teaching是现在进行时态)
(三)作定语
动词-ing形式作定语只表明它所修饰的词的用途、所属关系等,置于被修饰词之前.
a working method 工作方法 a dining car 餐车
a swimming pool 游泳池 building materials 建材
(四)作宾语
在某些动词:suggest, finish, avoid, stop, can't help, mind(在乎),admit, advise, consider, deny, enjoy, require, postpone, delay, practise, fancy, excuse, pardon, miss(错过)等后面不能用不定式,而必须用动名词作为宾语.
I can't help laughing.我禁不住笑了起来.
Return the book to the library as soon as you finish reading it.你一看完这本书就还回图书馆.
He enjoys watching TV plays.他喜欢看电视剧.
点拨
有些动词后既可用动名词,也可用不定式.
在动词love, like, begin, start, continue等后,既可用动名词作宾语,也可用不定式作宾语,有时两种结构的意义差别不大.
(五)作宾语补足语
动词的-ing形式用作宾语补足语,常用在:see, hear, notice, watch, keep, find, feel, get, have等动词之后,与一个名词或代词构成复合宾语;其中宾语和宾语补足语是主谓关系.
I saw him walking across the street.我看见他穿过街道.
He kept me waiting for a long time.他让我等了很长时间.
We watched the army marching down the street towards the park.我们观看部队沿街道朝公园行走.
I heard her playing the piano.我听见她在弹钢琴.
点拨
在see, hear, feel, watch, notice等动词之后,既可用动词-ing形式也可用(不带to的)动词不定式作宾语补足语:如用动词-ing形式,通常表示动作正在进行;用动词不定式,则表示(或强调)动作从开始到结束的全过程.
(六)作状语
动词的-ing形式短语作状语时,通常都表示主语正在进行的另一动作,用来对谓语动词表示的动作加以修饰或作为陪衬,它可表示时间、原因、结果、条件、让步、方式或伴随动作,相当于相对应的状语从句.
Seeing the teacher entering the room, the students stood up. =When the students saw the teacher entering the room, they stood up.学生(们)看见老师进房间,都站了起来.(两个动作同时发生)
Being ill, I went home.=Because I was ill, I went home.由于生病,我回家了.
The snow lasted a week, resulting in a serious traffic confusion in the whole area.=The snow lasted a week, so it resulted in a serious traffic confusion in the whole area.雪下了一个星期,造成整个地方的严重交通混乱.
Be careful when crossing the street.过马路时,要小心.
The students walked out of the classroom, laughing and talking.学生们有说有笑走出教室.
点拨
动名词也可以和about, against, at, before, after, by, besides, for, from, in, on, upon, without等介词构成短语,作状语用.
Without saying good-bye, she left him.未告别,她就离开了他.
After reading the passage twice, he began to do the exercises.这段文章看了两遍后,他就开始做练习了.
Upon returning from Beijing, he went to visit his friend.从北京一回来,他马上就去拜访朋友.
三、-ing分词的否定式
-ing分词是动词的一种非限定形式,其否定式是一律在其前面加否定词“not”或“never”构成.如:
I think it will do you a lot of good not going.我觉得不去对你会有好处的.

六、动名词作宾语和动词不定式作宾语含义不同
部分动词可加动名词作宾语,也可加动词不定式作宾语,但意思不同,如:
(一)remember doing sth.表示“记得过去做过的一件事”,remember to do sth.表示“记得要去做某事”
I remember seeing him once somewhere.我记得在哪里见过他一次.
