One day, there was a crow flying in the sky. It was summer, so it was very hot. The crow was very tired and thirsty, so he wanted to drink some water. The crow was in a tree. Suddenly, he found a bottle. In the bottle, there was some water. The crow was very happy. It flew to the bottle, but there was only a little water, and the neck of the bottle was very small. The crow couldn’t put his beak into it. Now, the crow wasn’t very happy, and it was very sad. Suddenly, it had a good idea. It found some stones, and he put the stones in the bottle. Now the water in the bottle was higher, and he could drink the water. He was very, very happy.
　　What a clever crow! Don’t you think so?
