用法辨析

    v. (动词)

  • know的基本意思是“知道”“认识”“听说”,指直接了解某事物,也可表示“领会,懂得”,指通过体验或传授而获得知识。
  • know既可用作不及物动词,也可用作及物动词。用作及物动词作“知道,懂得”解时,可接表示事物的名词、代词、带疑问词的动词不定式、that或疑问词引导的从句作宾语,也可接以“(to be/as+) n./adj./prep. -phrase. ”或动词不定式充当补足语的复合宾语。作“认识,了解”解时,可接表示人或物的名词作宾语。know可用于被动结构。know接to be作宾语补足语时, to be常可省略,但当to be表示的时间先于know表示的时间时,须用不定式的完成式,且不可省略。
  • 在对话回答语中,如know的宾语表示的是整个事实(如that-clause),则宾语可省略; 如know的宾语是一个具体事物,则通常以it代替之。
  • know是表示思想状态的动词,指思维活动的结果,通常不用于进行体。
