【答案】Dear Jim，
    I'm glad to hear from you.In the past，books were made of bamboo.So they were heavy and expensive.And they were not easy to carry.Now books are made of paper.They are light，cheap and easy to carry.
    I would like to share my favourite story Tom Sawyer paints the fence with you.
The story Tom Sawyer paints the fence was written by Mark Twain，who was well-known around the world because of his interesting novels.There are some characters in the story，including Tom，Becky，Ben，Aunt Polly and so on.Of course，Tom，the naughty but lovely boy is one of the main characters.
    The story took place one afternoon in a town.Tom was required to paint the 3-yard-long fence by Aunt Polly.It was such hard work that Tom actually was unwilling to complete it.Suddenly，he thought of an idea.When his friend passed by，Tom pretended to enjoy painting the fence and it was great fun to do it.Therefore，his friend became interested and begged   Tom for a try.Later on，more boys were tricked into painting the fence and even offered their food and toys.At last，the fence got 3 coats of paint.For Tom，he won Aunt Polly's praise and his friends' toys and food as well.
    In my opinion，the story is so interesting and enjoyable that it is worth reading.
