One hot and sunny afternoon three boys were walking towards the river.They were going there to swim and fish.On the way they passed by a green field.There was a wooden fence around it.A bull(公牛）was quietly eating grass inside.
“Ha!Ha!Look at the old bull!” One of the boys shouted.
“Doesn’t he look foolish?” Another boy laughed.
The boys picked up some stones and threw them at the bull.The bull looked at the boys and went on eating.The boys laughed and walked on.
Soon the boys reached the river.They took off their clothes and jumped into water.They swam for about an hour.After that they dried themselves in the sun.Then they put on their clothes and sat on the riverbank to fish.They caught a few fish.
Later they climbed up a tree to pick fruit.They ate many and filled their pockets with some.Then they started to climb down.
