     It was a Saturday afternoon. The weather was sunny and very hot; nobody wanted to stay at home.

Timmy decided to go swimming in the river. His little brother, Bob, wanted to go with him. "Take him

with you, Timmy," said their father, " and you must look after him well."

     When they got to the river, they saw a lot of people swimming in it. Some people had great fun playing

in the water. Timmy told Bob to play on the bank (岸上), and then he jumped into the water. About an

hour later, Timmy swam back to the bank with a fish in his hand. Bob was very happy. He found a bottle

and put the fish into it. Then they went home.

heard Bob crying in the room. He ran to him and asked, "What's wrong with you, Bob?" "The fish is dead(死的)." Bob said. "I thought it was tired, so I took it out of the bottle and put is on the chair. I only
