A

       There was once a tree. It was the biggest tree in the forest. However, the tree would never share its shadow (阴影) with any of the animals and wouldn't let them come anywhere near.

       One year, the winter was terrible (令人不快的). And the tree, without its leaves, was going to die of cold. A little girl found the poor tree when she went to live with her grandma that winter. So she went to get a great scarf to warm the tree up. At that time, the Spirit (仙子) of the Forest appeared. She told the little girl why that tree was so lonely and why no one would help it. Even so, the girl decided to put the scarf on the tree.

       The next spring, the tree learnt from the girl's kindness. When she sat next to it, the tree put itself down to give her shadow and let her keep away from the sun. The Spirit of the Forest saw this and went to tell all the animals. She told them that from then on they could get shadow from the tree, because it learnt a lesson. If there are more kind and generous humans around, the world will be a much better place to live in.

动物的尾巴

   大家都说动物的尾巴有用，它们到底有什么用呢?力力和强强两位小朋友想弄明白。星期天，爸爸带着他俩来到森林。

“笃（dǔ）、笃、笃……”这是什么声音?啊，原来是啄（zhuó）木鸟在给大树治病。“啄木鸟医生，”力力喊着，“你的尾巴有什么用?”爸爸笑着说：“你们先看看它是怎样停在树上的。”力力和强强仔细一看，啄木鸟用趾（zhǐ）钩抓住直立的树干，用尾巴撑在身体的下面，稳稳当当地坐着。我们明白了，啄木鸟医生的尾巴能当小板凳，它是坐在尾巴上给大树治病的。

“快看，小松鼠。”强强拉了拉爸爸。只见一只可爱的小松鼠张开蓬松的尾巴，正从大树上向下落。那毛茸（róng）茸的大尾巴就像一个撑开的降落伞，又稳又轻地把小松鼠送到地上。

        爸爸告诉他们，松鼠的尾巴还可以当大毛毯。松鼠睡觉的时候，尾巴一翘（qiào），头一缩，身子就全被盖到尾巴下面，睡起觉来暖和极了。
