在我家楼顶上,放着一个大纸杯,是用来盛水浇花的。去年夏天的一个中午,我意外地发现了奇特的一幕———一只小麻雀落在了树枝上喝水!从这以后,我没事总喜欢呆在楼顶上等候小麻雀的到来,然后观察它的一举一动。一天下午,小麻雀又来了,它先是在杯子上空飞来飞去,张望着有没有人,? In the roof of my house, stood a large paper cup, is used to water the flowers. A noon last summer, I accidentally discovered a strange scene --- a sparrow fell on the branch to drink water! Since then, I always like to stay on the roof wait for the arrival of small sparrow, and then observe It's every move. One afternoon, the little sparrow came again. It first flew over the cup and looked at someone.
