词组 trace
释义 trace
tracev. [treɪs] (traces; traced; tracing)
双解释义
1. vt.追踪;追溯  track; follow or discover sb/sth by observing marks, tracks, bits of evidence, etc.
2. vt.发现;找到  discover; find
3. vt.描绘;标出  draw or sketch the course, outline, etc.; mark out
4. vt. & vi.缓慢而困难地书写  write slowly and laboriously
基本要点
1. 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”。
2. 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。
