Reading Passage
It was the night before the big class trip to Washington, D.C., and everyone was buzzing with excitement. After packing her backpack and laying out her clothes, Jasmine was ready to hit the hay. Her little brother, though, was still watching cartoons and didn’t want to hit the sack yet.
Jasmine’s mom came in to tuck her in and gave her a goodnight kiss. “Time to catch some Z’s,” she said. But Jasmine was too excited to sleep. She tossed and turned for a while, and then finally started to drift off. Just as she was about to fall asleep, she heard her dad snoring in the next room he was really sawing logs!
Suddenly, the alarm clock buzzed. Jasmine had only managed to catch forty winks. She got up and saw her brother still in bed. “Lights out was hours ago!” she said. He just mumbled and hit snooze again.
At the bus stop, Jasmine told her best friend, “I didn’t sleep much. I think I was out like a light for only an hour.”
