用法讲解

v. (动词)
  1. 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。
  2. 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。
  3. 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。
  4. 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。
v. (动词)
know, know about, know of
  • 这三者都有“知道,了解”的意思。它们的区别是:know 表示直接地知道,熟知；而know of 是间接得知(听人讲过,从书报上看过等); know about指知道关于某事的情况。例如:
  • I know of him, but I don't know him personally.我听说过他,但不认识他。
  • It is better to know one thing than to know about ten thousand things.熟知一事要比略知万事要好。
    • know by, know to
  • 这两个短语的区别很细微:
  • 1.know to的意思是“为大家所了解”, know by的意思是“被大家所熟知”。现代英语中be known to较少使用。例如:
  • He's known to everybody here.
  • 这里的人都熟悉他。
  • He's known by everybody here.
  • 这里的人都了解他。
  • 2.know by的主动形式往往用于表示认识人〔事物〕的手段或标准。例如:
  • We know a judge by the clothes he wears.我们可以根据他穿的衣服认出法官。
    • know, learn, understand
  • 这组词都有“了解”的意思。它们的区别是:know指对某一事物的直接了解或通过体验、传授获得知识; learn意为“听说”“得知”,强调对某一具体事物从“不知”到“知”的变化; understand指对某事物的性质、规律、意义等都十分了解,而且还指了解它所包含的其他意义和关系,其程度要比know了解得更深、更广。例如:
  • How had he learned that secret?他怎么得知这个秘密的?
  • They were greatly surprised to learn the news.听到这个消息,他们都很吃惊。
  • Do you understand the difficulty of my position?你了解我处境的困难吗?
    • know, realize
  • 这两个词的共同意思是“理解,领悟”。其区别是：
  • realize指全面透彻地了解,语气比know强; know指知道、懂得、会做某事,不如realize了解得透彻、全面。例如:
  • So far as I know, he's abroad.据我所知,他在国外。
    • know, recognize
  • 这组词都可表示“认识”。其区别是：
  • 前者指“认出”,表瞬间动作; 后者指“认识”,表持续动作。
    • I don't know, I wonder
  • 参见wonder条。
    • know，learn，comprehend，understand
  • 这些动词都含“懂、知道、明了”之意。
  • know普通用词，多指通过学习、经验或他人传播而得到知识，含直接知道的意味。
  • learn通常指通过他人而获得消息或情况，侧重从不知到知的变化过程。
  • comprehend侧重熟悉了解的过程。
  • understand指对事物已有彻底的认识，不仅知其性质、含义和细节，而且了解其内外的关系。
