易混词辨析
reverse、cancel、abolish、annul
1. undo:动词“撤销;解开;破坏”(侧重“撤销已做的动作或解开某物”,搭配“undo a mistake 纠正错误;undo a button 解开纽扣”,如“He tried to undo the damage. 他试图弥补造成的损害。”);
2. undo vs. reverse:reverse动词/名词/形容词“颠倒;反转;相反的”(侧重“使事物反转或回到之前状态”,如“reverse a decision 撤销决定”),可与undo换用,reverse更正式;
3. undo vs. cancel:cancel动词“取消;撤销”(侧重“取消计划、订单等”,如“cancel a meeting 取消会议”),undo范围更广,可指“解开实物”;
4. undo vs. abolish:abolish动词“废除;废止”(侧重“正式废除法律、制度等”,如“abolish a law 废除法律”),undo无“正式废除”含义。
