太阳，月亮和地球是三个孪生兄弟。一天宇宙老师说：“下星期一考试请各位同学做好准备。”
Thesun,themoonandtheeartharethreetwinbrothers.Onedaytheuniverseteachersaid,"pleasegetreadyfortheexamnextMonday."
回去后太阳用功的读书复习每天都很用功。地球择是劳逸结合每天写完作业后玩会儿在复习。月亮回去后每天和伙伴玩。银河妈妈经常说他，可他总也不听。

礼拜一到了，太阳早早的来到了学校他把教师打扫干净后就开始复习，一会儿，大家都来了。宇宙老师走进教师对大家说：“太空小学，六年级下半年期末考试现在开始。”考卷发下来后大家都认真的答题，只有月亮在东张西望。宇宙老师看见了就把他的考卷给没收了。宇宙老实说：“让你不好好复习，这回知道了吧!”

考试成绩出来了，宇宙老师说：“这次考试第一名是太阳100分，第二名是地球，第三名是玫瑰星云，最后一名是月亮0分。大家听后纷纷取笑月亮，月亮羞愧不已。”

从此月亮就有了微弱的光，在外上就会出来和人相见，在晚上带给我们一丝光明。
