Nick is a careless(粗心的) boy. His room is often a mess(一团糟). Look! His blue jeans are on the desk. His white shoes are on the chair. His football is on his bed! Where are his red socks? They're in his black schoolbag on the floor. There is a mouse behind the door. It's eating some bread left(留下)by Nick. His mother is angry with him. She asks(要求)him to clean the room himself.
