         近几年来我国实行了师范生免费教育政策。假定你是某高中高三学生李华, 你的朋友约翰在网上看到了这方面的信息后, 给你发了一封邮件。下面是他刚发给你的电子邮件, 请根据邮件内容给你的朋友约翰回复。词数：120～150。

Dear Li Hua,

     I just happened to learn that China is giving free education to normal university students. What do

your schoolmates think of the policy? You are going to take the College Entrance Examination. What

are you going to study? Do you want to be a teacher yourself? I'm really interested in your response.

                                                                                                                                          Yours,

                                                                                                                                           John
