语法解析
动名词作主语
1.动名词概述
动名词由动词原形加-ing构成,兼有名词和动词的特征和作用,其动词特征表现在
它可以带宾语、状语或表语。动名词的否定式是在其前加 not.
·Going to bed early and rising early is a good habit.早睡早起是一个好习惯。
·I dreamed of becoming a scientist. 我梦想成为一名科学家。
· I'm sorry for not having informed you earlier.很抱歉没有早点儿通知你。
(2)动名词主要有以下几种形式:
形式 主动语态 被动语态
一般式 Doing Being done
完成式 Having done Having been done
·Retelling stories is very useful. 复述故事是很有用的。
·Do you mind being left alone at home 把你一个人留在家里你介意吗?
·He apologized for having broken his promise.他因未遵守诺言表示抱歉。
·He was ashamed of having been scolded by his father.他为受到父亲的责备而感到羞愧。
2.动名词作主语
动名词作主语表示一般的、抽象的、泛指的概念。
·Working in these conditions is not a pleasure but a suffer.在这种条件下工作不是一件愉快的事而是一件痛苦的事。
有时用it作形式主语,而将作真正主语的动名词放在句末。
常见句型有:①It is+no use/no good/no fun/a waste of time等名词+doing sth.
·It is no use telling him not to be upset.
告诉他不要难过是没有用的。
·It is a waste of time talking about that. 谈论那件事是浪费时间。
②It is+useless/nice/good/interesting/worthwhile 等形容词+doing sth.
·It is useless discussing the matter with him.q
和他讨论这件事是没有用的。
·It is worthwhile having a try even if you may fail.
即使你可能失败,也值得一试。
There is no+动名词为常见结构,相当于It is impossible to do sth.
·There is no joking about such matters,这种事开不得玩笑。
·There is no hiding of evil but not to do it. 若要人不知,除非己莫为。
【学法点拨】动名词作主语多表示一般的、抽象的、泛指的概念或一个已经完成的动作,强调的是事情本身。而不定式作主语表示具体的某一次行为或将来的动作,强调的是动作本身。不过有时二者区别很小。
·Climbing mountains is great fun. 爬山很有趣。
·To visit China is my next goal. 去中国旅游是我的下一个目标。
