Dear David,
How about you? I'm so glad to tell you sth about my experience. The exchange activity is about the visitors who comes from American senior high school to launch activity with us. It's an amazing chance for me to practice my oral English and know more about their daily life. And I want to listen some advices about my study English from you.
Yours,
