1. 假如你是李明，你收到你的外国朋友的一封咨询信：

Dear Li Ming，

    For the coming winter vacation（寒假）, my family and I want to spend our vacation in a place for seven days. We would like to go somewhere in China not only warm but also interesting. We don't mind how far we have to go. It has to be a place where we can swim every day, and it would be nice if our hotel is not expensive but clean and comfortable. We like to pay no more than ￥6000 for the trip. Could you please give us your suggestions（建议）for vacation spots（景点）?

Thanks a lot.

Yours,

Robert
