当然是月亮

ZX68

Two boys are talking about the sun and the moon. "Which one of them is more useful?" asked one of them.
两个男孩在谈论太阳和月亮。“它们中哪个更有用？”其中一个问道。
"Of course the moon is. The moon is in the sky when it's dark, but the sun is in the sky in the daytime when nobody needs it."
“当然是月亮。月亮在天黑时挂在天空，但太阳是在白天谁也不需要它时挂在天空。”
