第34讲 非谓语动词
第二部分 语法
这一讲要求掌握动词不定式的构成和用法,掌握动词-ing 形式的常见用法和动词过去分词的常见用法。
非谓语动词包括动词不定式、动名词、现在分词和过去分词。它们具有动词、名词、形容词和副词的特征,在句中不可作谓语。
一、动词不定式
动词不定式由“to+动词原形”构成,其否定式由“not to+动词原形”构成, “for +名(代)词+不定式”,即 for sb. to do sth. 构成不定式的复合结构。
动词不定式无人称和数的变化,在句中不可作谓语,但它仍保留动词的特点,有语态的变化,可以和自己的宾语、状语构成动词不定式短语。
1. 动词不定式具有名词、形容词、副词的特性,可以作主语、宾语、宾语补足语、表语、定语和状语。见下表:
2. 接动词不定式作宾语的常用动词有 begin, start, want, decide, fail, hope, wish, learn, love, like 等。
3. 接动词不定式作宾语补足语的常用动词有 ask, tell, want, help, teach, like 等。
4. 动词不定式省略 to 的动词有:(1)感官动词 see, notice, watch, hear, feel, observe 等;(2)使役动词 let, make, have;(3)在 help 之后,不定式可以带 to, 也可以不带 to。
5. “疑问词+动词不定式”(疑问词 why 没有此用法, 不定式的逻辑主语常为句中主语)构成的不定式短语在句中可以作主语、宾语和表语。例如:
I don’t know how to make a milk shake .(作宾语)我不知道怎样制作奶昔。
Where to go has not been decided yet.(作主语)还没决定去哪里。
二、动词-ing 形式(动名词)
动词-ing 形式既是动词现在分词,也可以构成动名词。构成动名词时,表示由这一个动词转换成的一件抽象的事,多用在介词之后。例如:
Thank you for coming. 谢谢你能来。
Forests help to keep water from running away. 森林有助于防止水流失。
接动名词作宾语的动词和动词短语, 见下表:
在复习动名词与动词不定式时要注意以下几点:
1. 动名词表示由抽象动作转化成的一件事,而不定式表示具体的、将要发生的动作。例如:
I like reading. 我喜欢读书。
They both like to read love stories. 他们俩都喜欢读爱情故事。
2. 有的动词后接动名词与动词不定式在含义上的不同。
(1)stop doing sth. 与 stop to do sth.: stop doing sth. 意为“停止正在做的事”;stop to do sth. 意为“停下来去做另一件事”。
(2)forget/remember doing sth. 与 forget/remember to do sth.:用动名词形式表示“忘记/记得做过某事”;用不定式表示“忘记/记得去做某事”。
(3)go on doing sth. 与 go on to do sth.:前者为“继续正在做的事”;后者为“接着继续做另一件事”。
(4)need doing sth. 与 need to do sth.: need doing sth. 表示“需要被做”,主语一般为物,相当于 need to be done;need to do sth. 表示“需要做某事”,主语一般为人。
(5)try doing sth. 与 try to do sth.: try doing sth. 表示“试着做某事”;try to do sth. 表示“试图(尽力)做某事”。
三、现在分词与过去分词
动词的现在分词与过去分词都具有形容词、副词的特征,在句子中可以作定语、表语、宾语补足语。现在分词与过去分词在用法上的区别主要有:
1. 现在分词表示主动,过去分词表示被动。请比较:
That lesson was quite interesting. 那堂课很有趣。(那堂课本身很有趣)
I was very interested in that lesson. 我对那堂课很感兴趣。(我在那堂课中被激起兴趣)
You may be worried if you have a worrying problem. 假如你有一个令人担忧的问题,你就可能感到担忧。
2. 现在分词表示动作正在进行,过去分词表示动作已经完成。请比较:
China is a developing country. 中国是一个发展中国家。
The USA is a developed country. 美国是一个发达国家。
3. 现在分词与动词不定式(省略 to)作感官动词的宾语补足语的区别:
(1)现在分词作宾语补足语表示所见到、听到的动作正在进行。例如:
I saw her dancing when I passed the classroom. 路过教室时我看见她在跳舞。(跳舞动作正在进行)
(2)动词不定式则表示所见到、听到的动作的全过程已经结束。例如:
I saw her break a glass yesterday. 昨天我看见她打破了一只玻璃杯。(打破玻璃杯的动作已经结束)

?
例3 —Who is the teacher going to have a picture for the wall newspaper?
—Charlie.
A. draw B. to draw C. drawn
(2020年广西柳州市中考题)
【解析】 此处 have 是使役动词,have sb./sth. do sth. 意为“使某人/物做某事(指一次性的具体的动作)”;have sth. done 意为“让/叫/使/请别人做某事”,宾语 sth. 后用过去分词作宾语补足语,说明 sth. 与过去分词表示的动作之间是被动关系;have sth. to do 意为“有某事要做”。本题是疑问句,疑问代词 who 作 have 的宾语,构成 have sb. do sth. 的结构,表示“让某人做某事”,此处应用省略 to 的不定式。句意:——老师打算让谁在墙报上画一幅画? ——查理。故答案选 A。
?
例4 Lisa plans a new picture next week.
A. draw B. to draw

A. not be B. not being
C. not to be
(2020年湖南邵阳市中考题)
【解析】 tell, ask 等动词后一般接带 to 的动词不定式作宾语补足语,构成 tell/ask sb. to do sth. 结构,意为“告诉某人做某事”;其否定式是 tell/ask sb. not to do sth.,意为“告诉某人不要做某事”。句意:——网上课程什么时候开始,格雷斯夫人?——8点钟。告诉辛迪不要迟到。故答案选 C。
?
例6 Reading is a good way the world.
A. for know B. for knows
C. to know D. to knows
(2020年甘肃天水市中考题)
【解析】 for 是介词,其后应跟动名词,所以排除 A 和 B 项;D 项形式错误。根据句意可知,此处是不定式 to know 作后置定语修饰中心词 way。句意:阅读是了解世界的好方法。故答案选 C。
?
例7 We should do what we can those people when they are in trouble.
A. to help B. helped
C. help
(2020年黑龙江龙东地区中考题)
【解析】 解答该题时,会有一部分同学一看到 can 就毫不犹豫地选 C。其实,这正是出题老师所设的陷阱。本题中 what we can 作 do 的宾语,can 后省略了动词 do,此处要用动词不定式 to help 表示目的。句意:当人们有困难时,我们应该尽我们所能去帮助他们。故答案选 A。

例8 Diana used to to work, but now she is used to because the road is crowded and she wants to keep fit.
A. drive; walk B. drive; walking
C. driving; walk
(2020年湖南益阳市中考题)
【解析】 used to do sth. 意为“过去常常做某事”,是固定结构,本身是一般过去时;be used to doing sth. 意为“习惯于做某事”,表示现在的状态,介词 to 后面只能跟名词、代词或动名词。根据句意“戴安娜过去常常开车去上班,但现在她习惯步行”可知第一空填 drive,第二空填 walking。故答案选 B。
?
例9 My mother reading books at home invited to dinners at times.
A. preferred; to being B. preferred to; rather than
C. preferred; than being D. preferred; to be
(2020年内蒙古呼和浩特市中考题)
【解析】 prefer 连接两个动作时构成 prefer doing sth. to doing sth. 或 prefer to do sth. rather than do sth. 结构。由第一空后的 reading 可知,此处应填 preferred,后面用 to doing sth. 连接第二个动词;再由句意可知,my mother 是动作 invite 的承受者,构成被动关系,所以第二空应用被动语态。句意:有时我母亲宁愿在家里看书,也不愿被邀请去吃饭。故答案选 A。
?
例10 He felt tired, so he stopped a rest under the tree.
A. having B. have
C. to have
(2020年四川甘孜州中考题)

A. troubles;turning up B. trouble;turning down
C. problem;to turn down D. problems;turning off
(2020年四川达州市中考题)
【解析】 have trouble/ problems/ difficulties (in) doing sth. 为固定搭配,表示“做某事有困难”,其中 trouble 是不可数名词。第一个空前为 some,所以排除选项 A 和 C。又根据句中 a bit 提示可推知是将音乐声调小,不是关掉,所以排除选项 D。 mind doing sth. 意为“介意做某事”,所以第二空应填 turning down。句意:——史密斯太太,我入睡有困难。你介意把音乐调小一点吗?——好的,当然不介意。故答案选 B。
?

A. to keep B. keep
C. keeping D. kept
(2020年四川遂宁市中考题)
【解析】 “It is+形容词+for sb. to do sth.” 为固定句型,意为 “做某事对于某人来说……”。 it 代替动词不定式作形式主语,真正的主语是后面的不定式,所以空格处应用 to keep。句意:保持健康的生活方式对我们来说很重要。故答案选 A。
?
例13 with my father’s handwriting, mine is poor.
A. Compare B. Compared
C. Comparing D. Compares
(2020年甘肃天水市中考题)

A. to water B. water

(2019年甘肃天水市中考题)
【解析】 see sb. doing sth. 是指“看见某人正在做某事”,表示正在进行,不是全过程;see sb. do sth. 是指“看见某人做过某事”,是看见事情发生的全过程(此处 do 前省略 to)。有类似用法的单词还有 hear, watch, notice 等。根据 when I passed by 这一语境可知,这里应该是“我”路过时看见她正在浇水,强调正在进行的动作,要用 see sb. doing sth. 结构。故答案选 C。
?
例16 —John, remember off the lights when you leave the classroom.

【解析】 remember to do sth. 意为“记得要去做某事”,这件事情还没有做;remember doing sth. 意为“记得做过某事”,这件事情已经做过了。有类似用法的单词还有 forget。根据 when you leave the classroom 可知事情还没有做,因此要用动词不定式,意为“记得关灯”。故答案选 C。
