John的来信:
Dear li hua,
I’ve just happened to learn from an article that most Chinese students are suffering from poor
eyesight and I am worrying whether you have things like that．Are you yourself nearsighted as well? What have you done to hurt, or protect your eyes? What would you suggest to improve the situation in general?
你的回信:
Dear John,
Just as you learned , most of us have eyesight problems．．．．．．．．．．．．．．．．．
