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.
