A famous circus comes to our town last week. On Saturday morning, all the performers marched brief down the street. The clowns（小丑）happily passed out balloons to the children whom waved and laughed out loud. My five-year-old sister closely watched the performers but waited eagerly for the clowns. Follow the performers, everyone had then walked into the big top. Though there weren't any animals in the circus, the performances turned out to being amazing. I was very impressed the sound effects, beautiful lights and performers' skills. Therefore, I'm exciting to know that the circus will stay in town for one more weeks.
