【解析】这篇短文给我们介绍了天空中的太阳和星星，有一些事实可能是我们之前不知道的，例如其实太阳总是在天空中闪耀着，只不过我们是夜晚的时候，它在地球的另一面闪耀。还有关于星星的一些事实，也会让你感到很惊奇的。

1.推理判断题。根据短文第一段的内容可知，太阳总是在闪耀，根据When the sun is shining on one side of the earth, it is night on the other side.可知，当太阳在地球的一面闪耀的时候，地球的另一面就是夜晚。由此可推断当是夜晚的时候，太阳在地球的另外一面闪耀，故选D。

2.细节理解题。根据短文第二段中The stars are in the sky all day. But the light from the sun is so bright that you can't see them.可知，其实星星一直都在天空上，但是白天的时候，来自太阳的光太明亮了，以至于我们看不到他们。由此可知应选C。

3.细节理解题。根据短文第二段中They look small because they are so far away from you.可知，星星之所以看起来很小是因为他们离我们很远。由此可知选A。

4.推理判断题。根据短文中Big things look much smaller when they are far away. The sun is closer to the earth than other stars, so it looks bigger.可知，大的东西在我们很远的时候看起来就更小，太阳离地球比其他星星更近，所以它看起来更大。由此可知选B。

5.细节理解题。根据短文的最后一句话The sun is closer to the earth than other stars, so it looks bigger.可知，太阳看起来比其他星星更大这是因为它离地球更近。因此选D。

点睛：这是一篇科普说明文，文章的内容涉及的是天空中的太阳和星星，短文中告诉了我们一些客观的事实，理解起来不是很难。后面题目的设置以细节理解题为主，我们要注意在题干中找到关键词，用它来帮助我们在短文中获取答案。例如第3小题，根据题干中The stars look small，我们在短文中找到星星看起来很小的相关句子，仔细阅读可知答案是A。
