考点名称:动名词

  • 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.

    动名词用法口诀:
    动名词常泛指,句法作用宾/表/定与主,时态/语态之形式,一般/完成/被动式。
    Being done 系被动,不含任何进行意。
    用作主语请留意,常用it作形式主语,不指未来发生事,表达的信息系已知。
    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
