英语语法经典例题800例:非谓语动词(例题1)
【导语】英语语法让很多学生都头疼,因为复杂难懂的句式和词组有时难以记忆。为大家整理了英语语法大全,希望对同学们的英语语法学习有所帮助。更多内容尽在。
1. Everyone in our class was working hard and doing what we could _______ a good college.
A. enter B. to enter
C. entering D. entered
【陷阱】容易误选A。有的同学一看到空格前的情态动词 could 就断定此处应填动词原形 enter。
【分析】其实正确答案应是B。此句为省略句,即在 could 后省略了动词 do,若把句子补完整应为Everyone in our class was working hard and doing what we could do to enter a good college。即句中的不定式短语(to enter a good college)是用作目的状语的,而不是与情态动词(could)一起构成谓语。请再看类似例句:
(1) They did what they could to comfort her. 他们尽量安慰她。
(2) They did everything they could to save her life. 他们尽一切力量拯救她的性命。
(3) He studies as hard as he could to catch up with his classmates. 他拼命学习以便赶上他的同学。
值得指出的是,这也并不是说今后只要遇到类似结构的题就一定选带to不定式。请看以下试题:
(4) He ran as fast as he could _____ to catch the early bus.
A. to hope B. hope
C. hoping D. hoped
此题的答案是 C不是A,其中的现在分词短语 hoping to catch the early bus 用作伴随状语。
(5) He spent every minute he could _____ spoken English.
A. practise B. to practise
C. practising D. practised
此题答案选 C,这与前面动词 spent 的搭配有关,即 spend … (in) doing sth。若将此句补充完整,即为 He spent every minute he could spend in practising spoken English.
(6) Before going abroad he devoted all he could ____D____ his oral English.
A. improve B. to improve
C. improving D. to improving
此题答案选D,注意两点:一是 devote … to … 是固定搭配,意为“把……贡献给……”;二是其中的 to 是介词,不是不定式符号,后接动词时要用动名词。
2. He knows nothing about it, so he can’t help _______ any of your work.
A. doing B. to do
C. being doing D. to be done
【陷阱】容易误选B,根据 can’t help doing sth 这一结构推出。
【分析】其实答案应选A。比较以下结构:
can’t help to do sth = 不能帮助做某事
can’t help doing sth = 禁不住做某事,情不自禁地做某事
又如下面一题,答案也是 B:
She can’t help ____ the house because she’s busy making a cake.
A cleaning B. to clean
C. cleaned D. being cleaned
再请看以下试题:
While shopping, people sometimes can’t help _____ into buying something they don’t really need.
A. to persuade B. persuading
C. being persuaded D. be persuaded
此题应选C,句中的 can’t help 意为“禁不住”(注意根据句意用被动形式)。
3. All her time _______ experiments, she has no time for films.
A. devoted to do B. devoted to doing
C. devoting to doing D. is devoted to doing
【陷阱】几个干扰项均有可能误选。
【分析】此题最佳答案为B。现分析如下:
(1) devote 意为“致力于,献身于”,主要用 devote…to…或be devoted to,其中的to 是介词,不是不定式符号,故后接动词时要用动名词,不用不定式。
(2) 选A错误:若将 do 改为 doing 则可以。
(3) 选B正确:all her time devoted to doing experiments为独立主格结构,用作状语。
(4) 选C错误:因为all her time 与 devote 为被动关系,故应将devoting改为devoted。
(5) 选D错误:若单独看 All her time is devoted to doing experiments,此句并没有错,但问题是逗号前后两个简单句没有必要的连接方式,所以从整体上看仍不对,假若在后一句的句首加上and或so,则可选D,或将D将中的is 改为 being也可选它。
