情帮我看一下这篇作文是否有语法错误(除大小写)

I play badminton well.I played badminton every Saterday last year .It can bring happiness to me.I do not like soccer,I think it is boy's sportsI like swimming.but not very well.I think it is a hobby ....为什么用keep呢？ hobby 用不用改为 only hobby最后一句什么以西？keep healthy是词组only a hobby.可以改最后一句是：我不喜欢运动，但是我知道运动可以使人身体保持健康。再问一下，什么是It can bring happiness to me.我们要双语翻译 不好意思……麻烦了it代表之前说过的话，我去年每个周六都玩羽毛球。这句话翻译为：这件事可以给我带来快乐。常规翻译：玩羽毛球可以给我带来快乐。
