您可以随意定义元素名称(airports、airport、city)，无需顾及它们是否与类的真实字段名称对应。

You can define any element name you'd like (airports, airport, city) regardless of whether or not they correspond to the class's actual field name.

“某一词汇如何被大众所理解”才是我们该问的，而非“某一词汇在字典上是怎样被定义”，其实字典要做的工作，也就是回答第一个问题。

"Is the proper question, not" how do dictionaries define X? ", since the dictionaries themselves are trying to answer that first question."
