本题考查七年级上册现在进行时的语法知识点，现在进行时结构为"am/is/are + 动词现在分词"，题干里的"正在"、提示词"Look!"都提示动作此刻正在发生，结合中文句意补全内容即可：
1. 主语Our school是单数，be动词用is，"举办一场表演"表达为have a show，用不定式表目的，"庆祝这个节日"译为celebrate this festival；
2. 提示词Look! 是现在进行时的典型标志，主语Shirley是第三人称单数，be动词用is，"坐在椅子上"译为sit on the chair，"玩她的玩具"译为play with her toys，两个并列的正在进行的动作用and连接；
3. 主语"他们"是They，be动词用are，"演奏一支名曲"译为play a famous piece of music，用介词by引出作品的所属家族。
