用英语写一篇我的寒假计划：
Dear Mr, Long
I'm writing now to tell you about my winter holiday plan this year. How time flies. I hope you have a good holiday too.
firstly, I will study hard during this holiday. I will finish my homework as well as do some previews of the subjects. Secondly, I will try to help my mother to do some housework, then I will do exercise with my father. Because exercising is very important and fun. Finally, I may go to the movie theatre with some of my friends. During the New Year I will visit my grandparents with my parents too.
Yours
