假设你叫李明，是美国中学生Tom的笔友。请您根据他给你的电子邮件内容写一封回信。谈谈你喜欢读的书及你对读书这种爱好的看法。

Dear Li Ming, I’d like to know what you often do in your free time. Do you spend much time on reading? What do you think about reading? I like reading novels (小说) very much. My favourite book is Jane Eyre. It was written by Charlotte Bronte. She was born in Britain. She was a famous writer in the world. She wrote many books and Jane Eyre was one of the best. In this book, she wrote about a woman named Jane Eyre. Jane Eyre wasn’t pretty, but she had a strong idea of self-respect (自尊心). She never gave up whenever she met any difficulties in her life. I was deeply moved by her story. I like the book very much. Yours, Tom

Hi Tom,
