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.
