短文写作。

   下面是21世纪报中学生版（21st Century School Edition）刊登的一封读者来信，请你以编辑的身份 给这位中学生写封回信。 Dear editor,     I spend most of my time studying. I hardly talk to my classmates. I just don't know what to talk about and how to begin a conversation.     I feel so lonely. How I wish I had a good friend! Could you give me some advice？ Yours, John 注意： 1. 回信的内容要包括以下提示要点，适当发挥。         （1）有自信；（2）多微笑；（3）多交流；（4）帮助同学。        2. 词数120左右。信的开头已写好，不计入总词数。 Dear John,    Your problem is a common one among middle school students. Maybe the following advice can help you.    _____________________________ ______________________________ ______________________________                                                                          Yours,                                                                           Lily
