Jack couldn’t believe it when he saw them. The trainers (运动鞋) were on top of a cardboard box, next to a pile of rubbish bins. And they look really good and brand new. He peered inside the trainers and found they were just his size. Jack cried out, “Why would anyone throw them away?” Anna shrugged. Anna was his best friend, but Jack didn’t expect her to understand. She knew that he liked running and she even helped by timing him when he ran around the park. But Jack didn’t just like running---he was crazy about it.
He unzipped his school bag and put the trainers into his bag. “It’s the Area Cross-Country Championships in two weeks,” he said. “I’ll never do well in my worm old trainers. These will give me a chance.”
Anna nodded. She knew how important the Championships were to Jack. Five runners were selected from each school in the area. Jack hadn’t been chosen, but then one of the runners had gone to hospital. So they picked Jack to be his replacement in the race. Jack knew he had no chance of beating Beadle, the best runner in the school. However, he would be happy if he just did okay in the race---he didn’t want to let himself down.
Much to their surprise, something unusual happened when Jack put on the trainers. Usually Jack set out at a light jog at first when he practised running. But this time he reached top speed straight away. He didn’t plan it---it just happened. It felt as if he was running on air. He zoomed round the park and kept picking up sped. In fact he just had to relax and the trainers did the running. However, Anna felt really upset. She knew no pair of normal trainers could make such a difference. Anna shook her head, “You shouldn’t wear them in the race. It won’t be YOU who wins, will it? Anyone could win if they wore those trainers.” But Jack wouldn’t listen. “I won’t give them up. These trainers are my only chance to win that Championship. I don’t need your help!” he shouted. With that he turned and ran off like a speeding train.
