　　Peter and Mike were in the same class. Peter was born in a poor family. But Mike's father was a shopkeeper and got a lot of money. When Peter was in trouble, Mike always helped him.

　　Peter liked to have sports. He was good at running. No boy could catch up with him in his school and he often won the boys'400-meter race.

　　It was Sunday. Mike and Peter went to a forest to have a picnic. Mike took a lot of delicious food there. It was a sunny day. The birds were singing and there were all kinds of flowers there. They ate and drank something and then began to catch fish in the river. The two boys had a good time there. Suddenly they heard a great noise. They looked around and found it was a tiger behind a big tree. They were both very afraid. Peter put on his shoes quickly and was going to run away. Mike stopped him and said, “It's no use for us. The tiger runs much faster than us. Let's find another way.” “It doesn't matter,” said Peter, “I'm sure I'll run faster than you!”
