用法辨析

    v. (动词)

  • reduce的基本意思是“减少”,指重量、程度、数目、范围、速度等减少或降低,不仅可以指量的变化,还可以指质的转变。引申可作“降职”“使…陷入某种状态或状况中”“将…概括或简化”“将…还原”“征服”“攻陷”等解。
  • reduce可用作及物动词,也可用作不及物动词。用作及物动词时接名词或代词作宾语。可用于被动结构。
  • reduce偶尔也可接动词不定式作宾语补足语,意思是“使…不得不…”。
  • reduce后常接介词by表示“以某幅度减少”或“以…方法减少”; reduce常接介词to表示“减少到…”或“使陷入…状态”。
  • reduce的过去分词reduced常可用作形容词,在句中作定语。
  • 当表达“使……不得不”的意思时，更多采用reduce…to doing(动名词)，而很少用动词原形；
  • reduce to和reduce by的意义不同。reduce to表示“减少到了”，而后者表示“减少了”，表程度。
