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(jīng)過后留下的痕跡，如足跡、轍跡等；也指證明某事發(fā)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(shù)名詞，也可用作可數(shù)名詞。
- trace還可作“微量”解，即少許，極小的量，可用于有形物，也可用于抽象事物，如某種情緒等。trace作“微量”解時可修飾另一名詞作定語。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(zhuǎn)化成動詞意思是“追蹤,追溯”,指根據(jù)一些已知的現(xiàn)象通過調(diào)查來得知某件事的起因或某個家族的起源等,不強調(diào)一步一步的追尋過程,而強調(diào)追溯的結(jié)果。引申可指“描繪,標(biāo)出”“緩慢而困難地書寫”。
- trace可用作及物動詞,也可用作不及物動詞。用作及物動詞時,后接名詞或代詞作賓語?？捎糜诒粍咏Y(jié)構(gòu)。
