用法辨析
- trace用作名詞的基本意思是“痕跡,蹤跡”,主要指人或物經過後畱下的痕跡,如足跡、轍跡等;也指証明某事發生或影響過某人某物的痕跡,可以是可見的,也可以是可感覺到的。trace作此解時可用作不可數名詞,也可用作可數名詞。
- trace還可作“微量”解,即少許,極小的量,可用於有形物,也可用於抽象事物,如某種情緒等。trace作“微量”解時可脩飾另一名詞作定語。trace與某些否定詞或具有否定意義的詞連用可表示強烈否定。
- trace用作名詞時意思是“纜繩”“痕跡”,轉化成動詞意思是“追蹤,追溯”,指根據一些已知的現象通過調查來得知某件事的起因或某個家族的起源等,不強調一步一步的追尋過程,而強調追溯的結果。引申可指“描繪,標出”“緩慢而睏難地書寫”。
- trace可用作及物動詞,也可用作不及物動詞。用作及物動詞時,後接名詞或代詞作賓語。可用於被動結搆。
- kick over/jump the traces指“擺脫控制”,這個普遍使用於英國;
- 在美國,人們習慣用work in the traces去表示“死板地工作”。
