    I was a bit of a bookworm as a child.For car journey,day trip or family holiday,many books were always packed to keep me busy.Since then,I've continued reading all kinds of books but I'll always love my childhood favorites.

    The Curious Incident of the Dog in the Night-timer—Mark Haddon

    This children's mystery novel is interesting,exciting,thought-provoking(发人深省的),sad and happy all at the same time.The main character is a 15-year-old boy who has autism(自闭症). The book gives you a window into his world, his thoughts, his hopes and his dreams. It's easy to read and both kids and adults love it.A must-read in my opinion.

    Secret Seven—Enid Blyton

    If you love adventures,this one is for you.The Secret Seven are a group of child detectives who make it their duty to solve crimes.They have many adventures along the way.It's a fun book that you won't want to stop reading. And in fact, there is more than.one book.There's a series of books about the Secret Seven's adventures so if you like the first one, you're in luck.

    Matilda—Roald Dahl

    It's now a film and show at the theatre,but we can't forget the original book.Matilda is about a loveable little girl who is very clever and,like me,loves to read.She goes to school and meets the very scary Miss Trunchbull who tortures(折磨)children,but thankfully makes friends with a kind teacher. The book will have you crying one, moment and laughing the next.

    The Lion, the Witch and the Wardrobe—C.S.Lewis

    As a kid I read the book, watched the film and listened to the tape.I really couldn't get enough of the book.It's an exciting story set in a magical land called Narnia. When you're reading it, you'll feel like you're really there.You'll get caught up in the adventures of the four children and the characters they meet.I can't rate it highly enough.
