我们坐地上休息可以用英文表示为："We sit on the ground to rest"。这个短语的来源可能是由于人们常常在户外或露天的地方休息，例如在野餐、野营或户外活动时。

一些英文例句和中文翻译如下：

We sat on the ground to rest after hiking for hours.
我们在徒步旅行了几个小时后坐在地上休息。
It was a hot day, so we decided to sit on the ground under a tree to cool off.
那天天气很热，所以我们决定坐在树下的地上冷静下来。
After the long walk, we were exhausted and sat on the ground to catch our breath.
长途跋涉后，我们筋疲力尽，坐在地上喘口气。
