泽熙美文目前学校正在讨论是否应变单一的教学体制为立体式教学――除单一课本授课外、采用多媒体及网络教学。请写一封信给学校报社说明你对此的看法。内容应涉及传统教学方法的局限性，立体教学优越性和局限性，二者互为补充。
A letter to the University Newspaper on Changing Teaching System
Dec, 23, 2006
Dear Sirs,
I’m sending you this letter to offer my opinions regarding whether we should change traditionally unitary teaching system into a tri-dimensional one, which has recently become a heated issue in your paper.
In my view, both traditional teaching and tri-dimensional one have their advantages and disadvantages. While traditional teaching does have such limit as restricting students’ vision, it offers a face-to-face communication between teachers and students that no other teaching can provide. Similarly, while tri-dimensional teaching offers a more convenient way of studying, it will somehow make students more passive simply because they have no opportunity to speak out.
Personally I think it would be better to integrate these two teaching methods so as to fully utilize their advantages and avoid their disadvantages.
