My friend is a sports lover. He is small, but he runs fast. And he is very friendly and kind. His favourite sport is basketball. He always plays basketball with his friends every day, and he practises basketball every day. Day by day, he is very good at basketball. But his leg was hurt last week. He said 'I never give up to play basketball.' It makes me very strong. So, I learn from him: Never give up doing every things. Now, I work hard at basketball too. It makes me very happy.（段评：本段围绕朋友的运动精神展开,主题积极健康,能体现"永不放弃"的核心思想。但作为记叙文,存在以下不足:一是人物形象扁平,缺乏具体细节(如朋友的外貌特征、打篮球时的动作神态等)；二是情节叙述简略,受伤的过程和心理变化未展开(如受伤时的场景、康复时的坚持)；三是情感传递较直白,"让我变强"的感悟缺乏具体事例支撑,未体现从朋友身上获得的真实触动。修改版：我的朋友小宇是个十足的运动迷,他个子不高,却像小猎豹一样跑得飞快,圆脸上总是挂着阳光的笑,对谁都热情又真诚。他最爱的就是篮球,每天放学后都会和伙伴们泡在球场,哪怕大汗淋漓也不停歇,运球、投篮的动作越来越熟练。可上周他练球时不小心扭伤了脚踝,肿得像个馒头。我去看他时,他却咬着牙说:"等脚好了,我还要继续练,绝不放弃篮球！"他眼里的坚定像一束光,让我心里一震。现在我也跟着他一起练球,每次想偷懒时,就会想起他受伤时的模样,这股劲头让我越练越开心。）
