假如你是李雷，你的美国笔友Peter了解到：去年12月,北京出现了几次雾霾天气。在那几天里,学校实行了“停课不停学”的措施。他想知道你在雾霾期间的学习情况。请你用英语写一封电子邮件,告诉他在雾霾期间你在家里做了些什么?你是怎样进行学习的？为了减少雾霾保护环境你打算怎么做?词数90左右。开头和结尾已给出,不计人总词数。

提示词语: heavy smog (雾霾), housework, study online, bad, health, duty, on foot

提示问题: What did you do at home?

    How did you study for your lessons?

    What are you going to do to protect the environment?

Dear Peter,"

    How is it going?

Last December, we experienced a few days of heavy smog. In order to keep our health, teachers asked us to stay at home.

    I'm looking forward to your early reply.

Yours,

Li Lei
