词源与构词

记忆钩子 up 作副词时可不带宾语,如 stand up;作介词时要接宾语,如 up the stairs。upon 则始终是需接宾语的介词。

词族与关联词

反义词
  • down 向下;下降
    up 与 down 都可作副词或介词,表示相反方向,也可表示数值升降;go up 是上升,go down 是下降,turn up/down the volume 是调高/调低音量。
    Prices came down after the initial rise. 价格在最初上涨之后降了下来。
易混词(形近或义近,注意区别)
  • upon 在……上面;一……就(正式)
    up 可独立作副词或短语动词的小品词,如 stand up 后不需要宾语,也可作介词表示向上;upon 只能作介词,后必须接名词、代词或动名词,主要相当于正式的 on,绝不能把 stand up 改成 stand upon。
