答案：
(答案→)B
解析：这篇文章主要讲述了太阳，月亮，地球的关系和白天黑夜的形成。由于离地球距离的不同，所以太阳，月亮和星星在我们看来大小不同。
【小题1】细节理解题。根据文中第一句The earth moves around the sun, and the moon moves around the earth.地球围绕太阳转，月亮围绕地球转，故选B。
【小题2】细节理解题。根据文中第二段But sometimes the moon looks bigger than the sun, because it’s much nearer to the earth.但是有时候月亮看起来比太阳大，因为月亮离地球更近，故选C。
【小题3】细节理解题。根据文中第三段The sun is very bright. It gives a very strong light.太阳很亮，它发出很强的光，故选A。
【小题4】判断推理题。文中最后一段But actually(实际上） the stars are much bigger and brighter than the moon. They look smaller than the moon because they’re much farther away from us.事实上星星比月亮更大更亮。它们看起来比月亮小因为他们离我们更远。由此可判断星星比月亮离我们更远，故选D。
【小题5】判断推理题。文中第一段When our part of the earth turns to the moon, it is night。当我们所处的地球这面朝向月亮时就是晚上。由此判断，当我们所处的这面地球朝向太阳时就是白天。故选B。
