用法辨析

    adj. (形容词)

  • open的基本意思是“开着的,开放的”,也可作“坦率的,无偏见的”解。作“空旷的,开阔的”解时,在句中只充当定语。作“开始营业的,(职位等)空缺的”解时,在句中作表语。
  • open作表语时,后面经常跟to或with短语, open在句中还可充当宾语补足语。
  • 说“让…开着”,可以直接用形容词open作补语表示状态,而不可用动词open的过去分词来表示。

    • v. (动词)

  • open的原意是把封起来的或合起来的东西打开或揭开,强调从紧闭的状态向开放状态的移动。引申可表示为“开始”“开设”等。
  • open既可用作及物动词,也可用作不及物动词。用作不及物动词时,多表示某物自身具有打开的性质。在与on, onto等介词连用时,表示“朝着,朝向”; 在与into, off等词连用时,表示“通向,通到,从…通入”。open用作不及物动词时,主动形式可含有被动意义。
  • open用作及物动词时,可接名词或代词作宾语,也可接以形容词充当宾语补足语的复合宾语。
