首先第一句話We are busy these days,意為這些天我們很忙.只是粗略地指出了一個時間段.
但是第二句話 In those days the workers had a hard time．意為在那些天里工人們都很辛苦.強調(diào)了一個特定的時間段.
We are busy these days． In those days the workers had a hard time．
We are busy these days． In those days the workers had a hard time．
We are busy these days．
In those days the workers had a hard time．我在一篇文章中看見這2句話
后面一句我明白需要加介詞in
我就是不明白為什么不能說 We are busy in these days
為什么第一句不加in介詞的
