Where is my pencil-box

　It's seven o'clock now. Kate is preparing her bag for going to school, but she found her pencil-box missing .” Where is my pencil-box?” 
　 Kate begins to search in the whole room, on the desk? In the drawer ? Under the bed? Behind the door? No, the bag was not found. 
　 It's seven thirty! Kate will be late for school if she doesn't go now. So she asks mother for help:” Mum, I can't find my pencil-box! Do you know where is it?” 
　 “Don't worry, my dear. Think carefully where and what time you last see it.”
　 “ Yesterday when I finished my homework I put it on my desk, later……Oh, I remember! When the sister in the neighbor come to borrow my eraser. I take my pencil-box out to the living room, and put it on the sofa .” 
　 As expected Kate found her lovely pencil-box. Then she goes to school happily.
