Have you ever wondered about the stars? In some ways, stars are like people. They are born. They grow old. And they die. A star is born from dust and gas. Slowly the dust and gas make a ball. The ball gets very hot. Then it starts to give off light. The young star grows into a giant. Many years go by. The older star begins to get small again. At last its light goes out. The stars life is over.
你可曾幻想过星星呢？在某些方面，星星就像人类。他们诞生了。他们会变老。他们会死亡。一颗恒星从尘埃和气体中诞生。慢慢的尘埃和气体形成一个球体。这个球体变得很热。然后它开始释放光能。新生的星体长成一颗巨大的恒星。许多年过去了。年长的星体又重新变小。最后它的光熄灭了。一颗星星的生命结束了。
