请以（My Summer Vacation）为题介绍一下你今年暑假的经历。要点包括：1 Where did you go

I had a busy and happy summer vacation. First I Jioned a swimming club .At first I couldn't swim. After three days of pracitce I learned swimming . I stayed in the club for twenty days. Now I can swim very well . I am very happy though i was tired when i was learning swimming.Every night in my vacation I spent about one hour doing my homework. I didn't like doing it.but I finished it at last. In August my father took me to Zhangjiajie. We had a good time there. The air is very fresh there and the scenery is very beautiful.I hope i can go there again. In my vacation I also helped my mother do some housework such as cleaning the floor,doing the dishes and so on , so My mother said I was a good boy!
