Abolish、cancel和repeal三词都有“取消、废除”的含义，但是用法不同，取消的对象有差别，以下介绍这三个词表示该含义时的具体用法。

Repeal是一个书面用书，较为正式，通常指的是撤销【协议、法案或法律】等。如：The government has just repealed the law segregating public facilities. 政府刚刚废除了隔离公共设施的法令。

Abolish是一个正式用词，指彻底废除某种【制度、规章或习俗】等。如：abolish the death penalty 废除死刑，This tax should be abolished. 这种税应该取消。

Cancel相比前两次而言用法广泛，多指【取消债务、合同、比赛、旅行、计划】等。在法律英语中，也可指【撤销，取消，废除（具有法律效力的协议）】，如：to cancel a policy 取消保单，cancel subscription 停止订阅，cancel orders 取消订单，cancel debts 免除债务。
