用法辨析

    v. (动词)

  • drop的基本意思是“落下”“投下”,表示某物体以垂直方向突然或偶然落下,通常强调下落的速度、直接性、突然性和偶然性,而这种“落下”的原因则可以源于地心引力,也可以是由于没有握住等,引申还可指家禽或兽类“出生”。
  • drop还可作“(使)降低”“减少”“减弱”解,引申可以表示地面沉降,价格下跌,数量减少,速度放慢,水准下降,势头衰落,声音压低,(因劳累、受伤、死亡等)倒下,联络中断,问题搁置等。
  • drop还可以引申表示让某人下车或留在某地,卸下货物,压低嗓门,放慢速度,丢弃或漏掉某物,停止或放弃做某事,改掉某习惯,不经意地说出或暗示。
  • drop在非正式用语中还可表示“散布”“透露”“投信或写信”。
  • 在美式英语中, drop可表示“解雇”“开除”,在美国口语中, drop还可表示“亏空,输钱”。
  • drop可用作不及物动词,也可用作及物动词。用作及物动词时,其后可接名词或代词作宾语; 作“不经意地说出或暗示”“寄信给某人”解时可接双宾语。可用于被动结构。

    • n. (名词)

  • drop用作名词时可指“落”的动作,即“降落”“下跌”“空投”等,也可指能“降落”的“水滴”“滴状物”。作抽象的“降落”解时,可用作不可数名词,也可用作可数名词,作具体的“水滴”“降落物”解时是可数名词。
  • drop引申可表示“微量”“一点”,这时只用单数形式,其后常接“of+不可数名词”。
  • drop还可表示“落差”,这时只用单数形式,其后常接“of+数量短语”,也可在其前加表示数量的短语修饰。
