I already sent someone the solutions. Please focus on the class material.
Don't worry too much about the problems in the back of each chapter even
though you are responsible for them. I am not in office and will not be
back until late tonight. So I guess the best time to help you out is
tomorrow morning. Good luck!
這是我寫信跟老師要解答的回信
我想第一句話
老師的意思應該是說某人已經有答案了
煩請同學將答案上傳到ftp吧!
