during three days与during the t

问题描述

有这样一组正误句子：
误：He stayed with his family during three days.
正：He stayed with his family during the three days.
正句与误句的区别就是一个冠词，为什么 during the three days 是对的，而 during three days 就是错的呢？

老师答疑

龙老师：

during可以用于一段时间，但必须是特定的时间段。如：

The clock stopped during the night. 钟夜里停了。

We talked during the entire evening. 我们聊了整整一个晚上。

Most people work during the day and sleep at night. 大多数人白天工作，夜晚睡觉。

During this past week, temperatures have fluctuated 50 degrees. 在过去这周里，温度波动达50度。

但英语不说：during some time, during ten years, during a lot of time 等。

米老师：

谢谢！
