sell out 的用法

题目

sell out 的用法
1.Mary went to the box office at lunch time,but all tickets had sold out
2.Mary went to the box office at lunch time,but all tickets had been sold out
这两个句子哪个是对的?

答案

2.对,“票”被“卖”,应当用被动态.
这里还有一个习惯的问题：
sell out 卖完 “票卖完了”用被动态,如果要说“这场表演的票卖得很好”就要说：
The tickets for the show sells well.
