"That's right，" Michael said．"We are．"

"What then？" asked Mrs． Walker．

"Then it happened． The bubble became as big as a beach ball．" He _____his arms to show how big it was．

"Suddenly a strong wind took the bubble right out of my mouth! The bubble_________over my desk and out of the window． As it sailed away， I noticed something yellow stuck to it． Like paper． Then I noticed my ___was missing．"
