The sun shone brightly in a cloudless sky.

太阳在无云的天空中明亮地照耀着。

The sun and the cloudless sky in the morning.

晨曦和万里无云的天空

Have you ever seen a perfectly cloudless sky?

你曾看到过万里无云的天空吗？

The great, cloudless sky. The rolling ocean of grass.

无云的浩瀚天空，起伏的茫茫草原。

A group of white pigeons spread their wings in the cloudless sky.

澄净的天空中，一群白鸽展翅飞翔。
