不定式和动名词作主语与表语比较
■表示一般的、泛指的或习惯性的行为用动名词;表示具体的、一次性的或将来的动作用不定式。如动名词作表语:
Swimming is fun in summer. 夏天游泳是有趣的事。
Swimming in this river is a great pleasure. 在这条河里游泳是件非常快乐的事。
注:有时这种区别并不很严格。但要注意:主语和表语要用同一种形式;平行结构中要用同一种形式。如:
To see is to believe. =Seeing is believing. 眼见为实。
Fishing is his favorite hobby, and collecting coins also gives him great pleasure 钓鱼是他的爱好,集邮也给他带来极大的乐趣。
■口语中,陈述句多用不定式作主语,而疑问句却总是用动名词作主语。如:
Is doing morning exercises good for your health? 做早操对你身体有好处吗?
■下列句子中通常用动名词:
It’s no good/use talking to him. 找他谈是没有用的。
It’s useless discussing the matter. 讨论此事无益。
There is no stopping him. 无法阻止他。
No parking! 禁止停车!
■下列句中通常用不定式:
It took us two hours to get there. 去那里我们花了两个小时。
It’s foolish of him to do so. 他这样做是愚蠢的。
It is necessary for us to learn English well. 我们有必要学好英语。
