Why do English speakers say hang up the phone? Nowadays， this seems meaningless given that most people have cell phones and they aren't 'hanging' them anywhere， but think about when phones were first invented. By fitting the language into its historical context， hang up makes sense. The phrase is still widely used but the technology has changed.

挂电话
为什么母语为英语的使用者说hang up表示挂电话呢？而如今，这对大部分使用手机的人而言并没有“hanging挂”的这个动作，但是想想电话在刚开始发明使用的时候。在这样的历史背景下，hang up挂电话就有意义了。这个短语仍然在被广泛地使用，然而科技改变了人们的生活方式。
