下面是21世纪报中学生英语双语版 (Student Times )刊登的一封读者来信，请你以编辑Henry的身份给这位中学生写封回信。
Dear editor,
I am a new student in Xin Hua Middle School. I hardly talk to my classmates. Sometimes I do want to talk, but I don’t know what to talk about and how to begin a conversation. I feel so lonely. And I spend most of my time studying but I find it’s more difficult and tiring than before, especially spoken English.
Could you give me some advice?
Yours,
Tom
