     It was a great day for a picnic and a picnic was a great day to start the summer holiday. Fred brought his

classmates John and Betty to a wonderful picnic place. After lunch, John said they should play football. When

the ball came to Fred, he locked it into some long grass. "I'll get it." he said and hurried off to find the ball.

Moments later there was a shout and out came Fred holding his leg,"I've bitten by a snake!" 　　

     As the others rushed over to help. Fred began laughing. "Ha! I'm not really hurt." But Betty didn't laugh, "I

can't believe you did that, Fred. I was really frightened for you." 　　

     The friends then decided to go for a swim. John and Betty jumped into the water. Fred was standing on a

long rock by the riverbank and said, "Watch me jump." They shouted excitedly as he went under the water, but

as the seconds passed he didn't come back to the top. The friends became worried. Suddenly they heard Fred's

laugh, "Won't you ever learn? I swam behind this tree when I jumped." 　　

     "Very funny, Fred?" said John angrily. "Anyway, I'm feeling tired and I'm going for a sleep." Betty joined

him. 　　

     Fred, however, moved to a narrow part of the river and jumped in. Although he was a good swimmer, the

water there was moving much faster and Fred found himself dragged away. He managed to catch hold of a tree,

but he was very tired now and with the water still moving very fast, couldn't pull himself out. 　　

     Back at the picnic place, as Betty and John were preparing to sleep, they heard Fred's cries for help, John

looked at Betty and said, "Does he really think we're so foolish? Wake me up in an hour. It'll be time to go back

home then."
