[单选题]下列对选文的理解和分析不准确的一项是( )

演出时，台下的掌声，评委们的感觉，都反衬了陆鹤表演的成功。

解析：B【解析】本题较难，考查的是学生对文章内容的理解、情感的把握、写作手法的运用及作家写作特色的掌握。B项中，“演出时，台下的掌声，评委们的感：觉”是对陆鹤的侧面烘托，不是反面衬托、，选文开头前三段，主要写了汇演中演秃头这一一角色所遇到的困难：上上下下为这一一角色苦恼。柳三不愿意演，大家都传言演不成了。这显然是对陆鹤出演秃头做了很好的铺垫，所以A项是正确的，、历缀艰难，同学们的演出最终获得了成功，大家都激动地哭了，所以，C项也是正确的。“情节生动，人物描写细致，场景描写优美”这蝗正是曹文轩的小说的特点，在文中都有鲜明的体现。所以，D项也是正确的。因此，答案应选B。
