One day， a boy went to the park for a walk. He ate a banana and threw the skin on the ground. A moment later， he came back. Without noticing the skin， he slipped （滑動） on it. He was hurt so badly that he couldn’t move. At the moment， someone passed by and called 120. Soon an ambulance （救护车） came and took him to the hospital nearby.
　　The boy paid for what he did. We must say no to his bad behavior （行为）. To make the world a better place， everyone must follow the social rules.
　　请遵守社会规范
　　一天，一个男孩去公园散步。他吃过一个香蕉后，随便把香蕉皮丢在地上。过了一会，他回来了。男孩由于没有注意到刚才自己丢弃的香蕉皮，摔倒在地。他伤得不轻，动弹不得。就在此时，有人经过这儿，拨打了120。不久，救护车来了，送男孩去了附近的医院。
　　男孩为自己的所作所为付出了代价。我们必须对男孩的不良行为说不。为了让世界变得更加美好，大家必须齐心协力，共同遵守社会规范。
