第一节One possible version:Dear Mr.Green,I'm sorry to learn that you feel discouraged and think that we are not fond of your class because we seldomraise our hands.As a matter of fact,we really appreciate your lessons.We hesitate to speak up largely becausewe fear making mistakes and feeling embarrassed;this fear is rooted in our cultural background.I would like to offer a few suggestions.Could you please give us more time to organize our thoughts afteryou ask us a question?Besides,group discussions can effectively encourage us to express our opinions.I hope these suggestions will be of some help.Yours,Li Hua
