动名词： 如果一个动词加上了-ing变成了名词，那么这个词称动名词。 动名词是一种兼有动词和名词特征 的非限定动词。它可以支配宾语，也能被副词修饰。动名词有时态和语态的变化。 例：Reading is an art. 读书是一种艺术。 Swimming is a good sport in summer. 游泳是夏天一项好的运动。 There is no saying when he'll come. 很难说他何时回来。 No smoking. (=No smoking is allowed here) . 禁止吸烟！ No parking. 禁止停车！ Let’s go shopping. 让我们去购物。
动名词常见题型: 1）动名词做主语时，谓语动词为单数 2）在动名词和不定式中，作为介词的宾语是动名词 3）动名词的否定直接在其前加否定词，通过代词的宾格或所有格形式给出逻辑主语 例： I would appreciate_______ back this afternoon. A．you to call B．you call C．you calling D．you’re calling （Key：C；换成your calling也对） 4）有些词后只能接动名词 acknowledge;admit; advise;advocate;allow;appreciate; avoid; celebrate; consider; contemplate; defer; delay; deny; detest; discontinue; dislike; dispute; enjoy; it entails; escape; excuse; explain; fancy; feel like; finish; forgive; can’t help; hinder; imagine; it involves; keep; it means; mention; mind; miss; it necessitates; pardon; postpone; practice; prevent; recall; report; resent; resist; risk; suggest; understand... 5）另外还有一些接-ing形式的常用说法 it’s no good; it’s no/little/hardly any/ use; it’s not/hardly/scarcely use; it’s worthwhile; spend money/time; there’s no; there’s no point in; there’s nothing worse than; what’s the use/point... 6）有些词后面加不定式和动名词均可 remember,forget,try,stop,go on,continue,stop,regret,cease,mean后面均可用不定式和-ing形式，但意义截然不容。 例： remember to do/doing： ①I remembered to post the letters.（指未来/过去未来将要做的动作） ②I remembered posting/having posted the letters.（我记得做过这个动作） forget与remember的用法类似。 regret的用法： ①I regret to inform you that…（我很遗憾地通知你……） ②I regretted having left the firm after twenty years.（为了“二十年前的离开”而遗憾。） try to（努力）与try +–ing（试验）： ①You really must try to overcome your shyness. ②Try practicing five hours a day.
