在英语中，当夜晚有些凉时，可以说是 "It's a bit chilly at night." 这个短语来源于古英语中的 "cild" 和 "cildra"，意思是寒冷。
例句：
It's a bit chilly at night, so don't forget to bring a jacket. (夜里有点凉，所以别忘了带上夹克。)
I always get a bit chilly at night, even in the summer. (我晚上总是有点凉，即使在夏天。)
The fire kept us warm, but it was still a bit chilly at night. (火炉把我们取暖了，但夜里还是有点凉。)
