一只鸟儿和一棵树是好朋友。鸟儿坐在树枝上,天天给树唱歌。树呢,天天听着鸟儿唱。日子一天天过去,寒冷的冬天就要来到了。鸟儿必须离开树,飞到很远很远的地方去。树对鸟儿说:“再见了,小鸟!明年请你再回来,还唱歌给我听。”鸟儿说:“好的,我明年一定回来,给你唱歌,请等着我吧! A bird and a tree are good friends. The bird sits on the branch and sings the tree every day. Tree, every day listening to birds singing. Day by day, the cold winter is coming. The birds must leave the tree and fly far and far. The tree said to the bird, “Goodbye, bird! Please come back next year and sing to me.” The bird said, “Well, I will come back next year and sing for you. Please wait for me!”
