                                    Clowning Around

    Its almost time for the summer holidays. The thought of sunshine，no school or homework and traveling around are in everyone s mind. However, a lot of teenagers stay at home during the summer holidays. If you dont have any plans this summer and want to team something cool and fun，why don t you try a circus(杂技）skill? There are plenty of skills that are easy to team with a bit of practice.

   Hula hooping is a good choice because it s a fun way to keep fit Once you ve teamed how to keep the hoop moving around your waist, you can try around your arms，legs and even neck！

     Or how about juggling? This is a skill that takes a little bit of practice regularly. If you master the basics，there are lots of simple tricks that look exciting.

Most juggling beginners start with three soft balls. You can throw and catch them so that one is always in the air and the others in your hands. After perfecting this skill，you can add more balls. Some people can juggle up to ten balls.

       To people who don t like the sound of hula hooping，perhaps diabolo is more suitable. This looks like two plastic cones（圆锥体）joined together at the tips placed on a piece of string held by the player. You can spin，throw and catch the diabolo to show off some interesting but simple tricks.

    All of these are exciting to try. Most of the equipment（装备）can be found in toy shops or some websites on the Internet Most cities will have a circus club for teenagers to try out the different tricks and they even offer workshops to teach the skills properly and safely. Once you find the skill for you，I m sure you It be practicing all summer long，eager to impress your classmates when September comes around again.
