I admire circus artists because they are agile and very talented. For example tightrope walkers can walk on at rope at great height. They______ their balance very well. Good clows________many emotions and entertain people. On the contrary, bad clows_______people laugh_______contortionists_______the illusion of having boneless bodies? Yes, of course. They_______their bodies in amazing ways! Magicians______the choice of someone in their audience. ______they______gravity? Yes! they can levitate. A magician_______a trick whithout rehearsing it many times! Jugglers_______ tricks, but i_______three balls at the same time. It`s difficut!
