假设你是北京一所中学的学生,叫王林,请根据提示,给你的笔友Rose写封信,告诉她北京一年的天气情况.

Dear Rose
I am very glad to hear from you. You asked me about the weather here in Beijing in your last letter. There are four seasons here. It's very warm in spring and the days are short. It's hot and rainy in Summer. People like swimming very much. In autumn it's cool and dry. We often help the farmers because it's the harvest season. It's cold and windy in winter. Sometimes it snows. Then we can go out and play with snow. How aout the weather like in your country? I am looking forward to hearing from you,
Yours
Wang Li
