用法辨析

    n. (名词)

  • trace用作名词的基本意思是“痕迹,踪迹”,主要指人或物经过后留下的痕迹,如足迹、辙迹等;也指证明某事发生或影响过某人某物的痕迹,可以是可见的,也可以是可感觉到的。trace作此解时可用作不可数名词,也可用作可数名词。
  • trace还可作“微量”解,即少许,极小的量,可用于有形物,也可用于抽象事物,如某种情绪等。trace作“微量”解时可修饰另一名词作定语。trace与某些否定词或具有否定意义的词连用可表示强烈否定。
  • v. (动词)

  • trace用作名词时意思是“缆绳”“痕迹”,转化成动词意思是“追踪,追溯”,指根据一些已知的现象通过调查来得知某件事的起因或某个家族的起源等,不强调一步一步的追寻过程,而强调追溯的结果。引申可指“描绘,标出”“缓慢而困难地书写”。
  • trace可用作及物动词,也可用作不及物动词。用作及物动词时,后接名词或代词作宾语。可用于被动结构。
  • kick over/jump the traces指“摆脱控制”,这个普遍使用于英国;
  • 在美国,人们习惯用work in the traces去表示“死板地工作”。
