星星
What Are Stars Like? 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 star's life is over.
星星是怎么樣的？ 你曾對(duì)星星很好奇嗎？在某些方面，星星就像人一樣。它們出生，變老，然后死亡。 星星在塵埃和氣體中誕生。慢慢地，塵埃和氣體形成了一個(gè)球。球越來越熱。然后它就開始釋放光芒。 年輕的星星長(zhǎng)成一個(gè)巨型的星星。許多年過去了，年老的星星又開始變小。最后它的光亮熄滅。星星的生命結(jié)束了。
