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要点：

（2）微笑面对同学，让他们相信你是友好的；
（3）先试着与一个和你同样害羞的或和与你有同样爱好的同学交谈，可以问一些学习上的问题，谈谈共同的爱好；
（4）帮助学习和生活上有困难的同学。
2．词数100左右。信的开头已写好，不计入总词数。
3．参考词汇：自信self-confidence
