On Martin's birthday, his father gives him a gift. It is a book without any pictures in it. His father says,"Son, it has a magic key(魔法钥匙)in the book. To find it,you'll have to read it. "
Martin doesn't like reading. But he starts reading it because he likes things about magic. The next morning, his father asks him,"Did you find the magic key?"
Martin looks for it, but there is no key. He stops reading the book because he thinks his father is trying to trick(哄骗)him into reading.
His younger sister, Amy, asks him for the book. After some days, Amy happily shouts," I found the key of the magic book!" And she can talk about all the words and places with that magic key.
That makes Martin interested in reading the book. At first it is difficult, but little by little, he is interested in the adventure(冒险). Suddenly, he finds that the book itself(本身)is the key of magic!"Thank you, Dad. You let me know every book has the key of magic. "
