乌鸦喝水

The Crow and the Pitcher

It was a hot day. A crow was very thirsty. He flew here and there, looking for water. At last, he found a pitcher under a tree. There was some water in it!

The crow put his beak into the pitcher, but the neck was too long and narrow, and the water was too low. He could not reach it. He tried to knock the pitcher over, but it was too heavy.

The crow did not give up. He looked around and had an idea. Near the pitcher there were many small stones. He picked up one stone with his beak and dropped it into the pitcher. Then another, and another. One by one, the stones went in, and slowly the water rose higher and higher. At last, the crow could drink!

生词：pitcher 大肚瓶／ beak 鸟喙／ narrow 窄的／ reach 够到／ knock over 打翻／ give up 放弃／ drop 投下／ rise 上升（过去式 rose）

科学小延伸：乌鸦的办法其实用了一个物理原理——排水。石头沉到水底，占了地方，水只好「让位」往上升。你泡澡时水面上升，是同一个道理。两千年后，这个原理有个专门的名字：阿基米德原理。

好句：Where there is a will, there is a way. 有志者，事竟成。

讨论：乌鸦试了几个办法？（直接喝→打翻瓶子→投石子）前两个失败了，他没有停在失败上。遇到难题，你的「石子」是什么？
