烏鴉喝水(Crow drink water)
There is some water in a bottle near a big rock.A bird is very thirsty.
He comes to the bottle and stands next to the bottle.But he can't drink the water,beacause the bottleneck is very long and narrow.
So he thinks and thinks,and then flies away.
After some time,he comes back with a small stone in his beak.He goes up to the bottle and puts the stone into the bottle.
He flies away and flies back again and again.He puts many stones into the bottle.
The water in the bottle comes up to its neck and the crow can catch up and drink the water.
