Today is Tom's birthday. After school he walks past the shop on the street corner. He looks into the window. That pair of trainers(运动鞋) is still there. He really wants to have them.

    He is very sad and walks away. He knows his mother can't buy him anything, because his mother has no money. The trainers are too expensive. He doesn't go home at once , because his mother can notice（注意）his worry. So he goes to the park and sits on the grass. Then he sees a boy in a wheelchair(轮椅). He finds that the boy moves(移动) the wheels with his hands. Tom looks at him carefully. The boy has no feet. He looks at his own feet. "It's much better（更好）to be without shoes than (比) without feet." he thinks. There is no reason for him to feel so sorry and sad. He smiles and thinks he is happy.

江城子·密州出猎

    老夫聊发少年狂，左牵黄，右擎苍，锦帽貂裘，千骑卷平冈。为报倾城随太守，亲射虎，看孙郎。

    酒酣胸胆尚开张，鬓微霜，又何妨！持节云中，何日遣冯唐？会挽雕弓如满月，西北望，射天狼。
