[知识点]中华文化叙事忆旧
[答案]例文:
Dear John,
I'm glad you are interested in Chinese tea. I hope my trip to Hangzhou National Tea Museum can interest you.
On May 5th, my family and I went to Hangzhou National Tea Museum. It is one of the most interesting museums that I've ever been to. At the museum, I learnt some information about tea and who invented the tea. When I saw there were many different kinds of tea, 1 just couldn't believe my eyes. The museum also taught us how to make tea and later we watched a tea art performance. It was enjoyable to watch the tea preparation as well as drinking the tea. How amazing! I've finally realized why my grandpa loves drinking tea so much!
Why don't you come to China and experience it yourself
Yours,
Chen Ke
