Here came the first snow this year. After lunch, the doorbell rang (门铃响了）. It was Penelope, Elton's next-door neighbor. "Elton，would you like to come outside and make a snowman with me?" Penelope asked. Elton wrinkled (皱起）his nose.
"Yes, yes. Elton would like to go." his mother said. She asked Elton to wear warm clothes and took him and his unhappy face outside. Penelope and Elton made the largest snowman in the neighborhood. At dinnertime, Elton came home happily, but the next morning, his unhappy face came back.
