一篇英语作文，好难写啊 假设你是李芳，暑假随你校组织的访问团去美国参观访问了几所中学

Dear Tina,
How are you? I’m now back in China. I had a wonderful time in America, which I will always treasure in my life.
First, I’d like to express my thanks for your hospitality and kindness when I was in America, It was so nice of you to show me around your school and introduce its history to me. Your school is amazing in that it has not only a beautiful campus but also strict discipline. Besides, the delicious food that you treated me to impress me deeply. Hopefully you can come to China some day, when I can have the chance to repay you in the same way.
Best wishes and remember me to your family.
Yours,
LiFang
