5. 重点句型
Firstly, exploring space has already made a difference in the fight against world hunger.
首先, 探索太空已经在与世界饥饿的斗争中发挥了作用。
【句式解构】
(1)本句中划线部分exploring space是动名词短语在句中作主语。动名词作主语时, 它已经将动作名词化了, 已把某个动作视为某种活动或是某件事情了, 动作意义很弱, 比较抽象。
*Seeing is believing.
眼见为实。
*Reading simplified English novels is an easy and enjoyable way of enlarging our vocabulary.
阅读简写的英文小说是扩大我们词汇量的一种轻松愉快的方法。
*Cheating in an exam ruins one’s character .
考试作弊毁坏人的品格。
(2)动名词作主语时, 也常用“It is. . . ”和“There is. . . ”两种句型。其中“It is. . . ”的句型常用于说明“某种活动或是某件事情是如何的”, 强调事物的性质、特征等。常用于It is后面的词有: no good, no use, useless, a waste, worthwhile, dangerous等等。而句型“There is. . . ”往往用于说明“不允许、禁止某种活动或是某件事情发生或存在”, 类似一种建议或命令。
*It is no use waiting for him any longer .
再等他也没有用。
*It is worthwhile consulting your tutor about it again .
很值得再向你的指导老师咨询一下这个问题。
*There is no joking about such matters .
这种事开不得玩笑。
*There is no denying the fact that China has made a rapid progress in every aspect since it was founded .
毋庸置疑, 中国自它成立以来已在各个方面都取得了飞速的发展。
*There is no littering about. 不许乱扔杂物。
【名师点津】
(1)当不定式(短语)、动名词(短语)或从句在某个句子中作主语时, 为保持句子结构前后平衡, 避免头重脚轻, 因此常用it作形式主语置于句首, 而将真正的主语放在句尾。此时it只起先行引导作用, 本身无词义。
(2)不定式作主语的动作意义较强, 这种动作往往是“要发生的一次性动作”, 较具体; 动名词短语作主语往往是经常性、习惯性的动作, 此时谓语动词用单数。
*Working with you is a pleasure.
和你一起工作是一件乐事。
*He realized that to go on like this was wrong.
他意识到继续这样下去是错误的。
*It takes me ten minutes to get home from my office .
我从办公室回家要花十分钟。
