My favourite sports is (改：are) playing basketball. I joined the basketball club last year and had some really wonderful experiences. I took part in basketball games and scored a few points. I learnt a lot from this (改：these) skills and I learnt the importance of team work. I also made many new friends and they always share their love for this sport with me.（段评：本段详细描述了喜欢篮球的原因和经历,内容真实具体！但存在一些语法错误: 1. 主谓不一致:"My favourite sports is"应改为"My favourite sport is"(sport用单数形式)。 2. 时态不一致:"they always share"应改为"they always shared"(与前面的过去时态保持一致)。 3. 词汇搭配:"from this skills"应改为"from these skills"(skills是复数,用these修饰)。修改版：My favourite sport is playing basketball. I joined the basketball club last year and had some really wonderful experiences. I took part in basketball games and scored a few points. I learnt a lot from these skills and I understood the importance of teamwork. I also made many new friends and they always shared their love for this sport with me.）

I think that sport (改：sports) is the best way to keep fit and relax ourselves.（段评：作为结尾,本段总结了运动的好处,点明了主题！可以进一步升华主题,比如提到运动对生活的积极影响,让结尾更有深度。修改版：I think that sport is the best way to keep fit and relax ourselves. It not only makes our bodies strong but also brings us joy and friendship.）
