It was October 1.It was Tom’s birthday. He saw a card on the table when he came back home. It said, “There’s a present for you, Tom. Look for it in your room.” Tom ran into his room. His parents were watching him and smiling. On his bed he saw a new red box. He thought his present must be in it. He opened it. There was nothing but a card in it. He took it out and read it. “Dear Tom, I’m your present. My first letter is in the word ‘pear’, but not in ‘bear’. My second letter is in ‘tell’, but not in ‘tall’, and you can find my last letter in both ‘bank’ and ‘ink’. What am I?” Tom thought hard and soon smiled, “Aha, I know, Mum. But where is it?” His mother told him it was in his schoolbag. What is it? Do you know?
