明晰规则
1.意义:动词-ing形式作主语往往表示一般性的、习惯性的行为;其被动形式为being done;其否定形式需要在动词-ing前面加not。
2.位置:①动词-ing形式位于句首;② it作形式主语时,将动词-ing形式后置。常见句型有:It is no good/no use/useless/a waste of time+doing sth.,意为“做某事是没有好处的/没有用处的/无用的/浪费时间的”。
3.逻辑主语:动词-ing形式作主语时,如果要突出动作的执行者,要在其前面加上动作的逻辑主语,这个逻辑主语通常为形容词性物主代词或名词所有格。
4.谓语动词的单复数:①动词-ing形式作主语时,谓语动词通常用第三人称单数形式;②两个或两个以上表达不同意义的动词-ing形式作主语时,谓语动词用复数形式。
