Reading passage
Last Thursday, Ms. Taylor’s class had a big decision to make. The school was planning a talent show, and students had to sign up. Some kids were on the fence, not sure what to do. Joey told Sam, “Just go for it! It’s not rocket science.” But Sam got cold feet before signing up. Still, he didn’t want to let the chance pass. He finally said, “Okay, I’ll bite the bullet and do it.”
On the day of the show, Ashley said, “Break a leg!” to everyone. The first act was a magic trick, and it went off without a hitch. Then came Mia, who was all ears backstage, waiting for her turn. She sang her song so well that the crowd clapped like crazy. Afterward, she said, “I feel like I’m on cloud nine!”
Later, things got out of hand when the lights started to flicker. Joey joked, “It’s raining cats and dogs inside!” But Mr. Clark fixed the lights quickly. The show continued, and no one let the cat out of the bag about the surprise ending. When it was all over, Ms. Taylor said, “You all hit the nail on the head!”
