Reading Passage: “The School Play Panic”
It was the big day for the school play. Everyone was buzzing with excitement, but Max was nervous. As the curtains opened, he stood frozen, his face red as a beet. He saw red when he noticed someone had moved his script. Still, he took a deep breath and began his lines.
Halfway through, a red light blinked backstage. It was a red alert. The sound system had failed. Ms. Reed rolled out the red carpet to fix it, calming the kids and telling them to stay ready. Meanwhile, Lily, the lead actress, tried to cover for the delay. She told a funny story, but it was a red herring and didn’t help much.
Backstage, Mr. Dale caught two students red-handed messing with the props. That raised a red flag. They were quickly asked to sit with the audience. Max finished his part, and by the end, the crowd looked like a sea of red; everyone had worn red shirts to support the theme.
The show ended with a cheer, turning this red-letter day into a memory they would always treasure.
