动词ing形式的位置与标志词
(1)动词 ing形式作主语时,可位于句首和句末。 (2)当动词 ing形式位于句末时,要用it作形式主语。此类句型常见的有:①It is a waste of time/money doing... 做……是浪费时间/钱的。②It is no good/ use doing... 做……是没有好处/ 没用的。③It is worthwhile doing... 做……是值得的。④It is useless doing... 做……没有用。⑤It is no fun/pleasure doing... 做……没有乐趣。
记住特例
当句型“There is no...”表示不允许/禁止某种行为的发生或存在时,需用动词 ing形式作主语。There is no denying that the environment goes from bad to worse.不能否认的是,环境状况正在逐步恶化。There is no joking about such a matter.这种事开不得玩笑。
动词 ing形式作主语时,如果要突出动作的执行者,要在其前加上所表示的动作的逻辑主语,这个逻辑主语通常为名词所有格或形容词性物主代词。
His/Tom's coming made us very inspired.
