Q: Why did the boy run around his bed?

Explanation: To catch up on something (such as sleep) is to do something you have not had time to do. You catch up on sleep by sleeping more after a time of little sleep. You can also catch up on the latest news by reading/ watching today’s news (or the newest tweets on Twitter, for example). Someone might say, “When I returned from vacation I had to catch up on the news/ my emails/ my homework …7 L( S6 p$ c4 U, T+ L, C! o# [
$ y$ }, x {0 }5 }To catch someone is to chase after that person until you can touch him or her. You might catch someone in a race; a police officer might catch a criminal. (You can also catch a ball but that is a different meaning).! {* _, L& |/ U7 Y* e, T1 @" F6 W
