假设你是李华.写信邀请你的美国朋友john 参加玉龙山露营活动.

Dear John,
We are going camping on yulong mountain this weekeed.There wil be 6 people being together at eight thirty this Saturday at the Railway station square.And then we will take a train to get there at eleven thirty.After enjoying a good time ,we will be back at Sunday afternoon.What we should do is to take some camping things we need,a camping tent is a must.What is more,sleeping bags,coats ,water and foods are all that we need.
I believ that we must have a good time we can set up our further friendship then,I hope you can join us.Looking forward to your reply.
Yours,
Lihua
