不定式和动名词作主语的区别
(1) 动名词作主语往往表示普通的、一般的行为,不定式作主语常表示某次具体的行为。不定式(或不定式短语)作主语时常用“it” 来代替,称为形式主语,真正主语(不定式)放在句尾。
如:
Collecting information about children's health is his job.
收集有关儿童健康的信息是他的工作。
It's necessary to discuss the problem with an experienced teacher.与一位有经验的老师讨论这个问题是有必要的。
(2) 常用不定式作主语的句型有:
① It's difficult (important,necessary)for sb. to do...
② It's kind (good,friendly,polite,careless,rude,cruel,clever,foolish,brave)of sb. to do...
(3) 常用动名词作主语的句型有:
① It's no good (use,fun)doing...
② It is a waste of time doing...
