在山上,气温很低可以用英文表达为:"The temperature is very low on the mountain."

这句话的来源是因为山地气候通常比平地要冷,这是由于山地的海拔较高,导致大气压较低,气温自然也会更低。

一些英文例句和中文翻译如下:

It's freezing on the mountain. 在山上好冷啊。
The temperature drops significantly at higher elevations. 海拔越高,气温就会明显下降。
I need to wear a jacket on the mountain because it gets cold at night. 我需要穿上夹克,因为在山上晚上会很冷。
The mountain air is crisp and refreshing, but also very chilly. 山上的空气清新,但也很寒冷。
