请帮我翻译“有一天，当世界都变了，别忘了天空原来的颜色”

Never forget the color of the sky used be if the whole world changes one day.

One day,don’t forget the original color of the sky when everything changes.

One day, when the world has changed, do Not forget the color of the sky it has been.

................., do Not forget the original color of the sky.

Never forget the original color，even the world is changed entirely some day

One day, the contemporary fields all changed, don't forget the sky original color

One day, when the world has all changed, do not forget the color of the sky it once was.
