英语语法：动名词
动名词即具有动作特征的名词。今天我们一起来学习与之相关的一些知识。 一)动名词的种类：1) 是名词，例：Seeing is believing.
2) 具有动词性特征可以带宾语，例：Starving troops is necessary.
二)动名词的形式：
一般形式：I don't like you smoking.
完成形式：I regret not having taken your advice.
被动形式：This question is far from being settled.
三)动名词常考的点：
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
admit; 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, 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.
