用作表语请记清,作用相当一名词,检验方法很简单,主与表换位能成立。用作定语也易辩,表示名词之用途。用作宾语稍复杂,关键留意谓语动词(跟动名词作宾语的常用动词附后),时态同谓动作比较,先于谓动用完成式,其逻辑主语不固定,在句中/句外均有之。否定式其前加not,复合式其前加物主词,非句首宾格词也可用,尤其口语中更如此。说明:1、主-----主语2、宾-----宾语 3、表------表语 4、定------定语 5、谓动---谓语动词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) 有些词后面只能接动名词acknowledge;admit; advise;advocate;allow;appreciate; avoid; be worth(后面的动名词必须是主动形式); celebrate; consider; contemplate; defer; delay; deny; detest; discontinue; dislike; dispute; enjoy; it entails; escape; excuse; explain; fancy; feel like; finish; forgive; hinder; imagine; it involves; keep; it means; mention; mind; miss; it necessitates; pardon; postpone; practice; prevent; recall; report; resent; resist; risk; stand; 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,但意义截然不同。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.
