I’ve always wanted to be a cheerleader. Yesterday, I tried out for the team. It was hard. First, we had to dance. The teacher showed us how to move, and then we tried. Second, we practised singing a song about the school basketball team. Finally, some girls had to lift their partners. The other girls jumped and cheered. I think I did well, but the other girls were better. I’m not sure whether I’ll make the team or not.
