    My name is Bob. Look, this is my bedroom. There are some books on the bed. There are two pairs of shorts on the chair. There are three pairs of socks on the floor. There is a pair of blue shoes on the window. The clothes in the wardrobe aren't tidy(整洁的). My mother always says angrily (生气地) to me, "It's so messy (凌乱的)! Clean your bedroom now!"
