Yesterday was Saturday and it was Tom's birthday. He saw a card on the table when he came back home. It said, "There is a present for you, Tom. You can find it in your room." Tom ran into his room. His parents were there and smiled. On his bed, he saw a new red box. There was a card in the box. He took it out and read. "Dear Tom, I'm your present. My first letter is in the word 'pear', but not in 'bear'. My second(第二) letter is in 'tell'，but not in 'tall'. You can find my last letter in both(都) 'orange' and 'ink'. What am I?" Tom thought(想) hard and soon smiled, "Aha, I know, mum. But where is it?" His mum told him it was in his schoolbag. Then he found his present in it. His parents said, "Happy Birthday! Happy Children's Day(儿童节)!"
