基本释义
[verb] alternate or waver between different opinions or actions; be indecisive
[动词] 在不同的意见或行动之间交替或摇摆；犹豫不决
深入解读
Vacillate 一词源自拉丁语 vacillare （来回摆动；犹豫）的过去分词 vacillatus ，16世纪末进入英语后也是用来表示因缺乏平衡而不稳定地“摇摆、波动、震荡”，比如：
- 地震使这座用回收的废旧材料建成的房屋摇来晃去。
The earthquake caused the house built using salvaged materials to vacillate.
等到了17世纪20年代后， vacillate 开始发展出现在的主要含义指观点或立场的“摇摆、动摇、犹豫、踌躇”，常意味着因无法作出固定不变的或最终的决定而导致长时间的犹豫，诸如在不同的意见、选择或效忠对象之间来回摇摆或不停转变，比如：
- 哎哟，别再犹豫了，打定主意吧！做生意不能感情用事。
Oh, do stop vacillating and make up your mind. There is no room for sentiment in business. - 这位情绪无常的女演员一会儿还和蔼可亲，可一转眼就火冒三丈。她时而心怀希望，时而感到绝望。
The volatile actress was affable at one moment, choleric the next. Her mood vacillated between hope and despair.
