When the plane was waiting at the airport, a big snake climbed up the steps and into the plane. It went to sleep under the pilot’s (飞行员的) seat. Nobody saw it. Soon the passengers (乘客) walked into the plane and it took off. A little girl called Mary took out a whistle (哨子) and began playing. But none of the passengers liked the music. Then the stewardess (女乘务员) asked Mary to stop.

The noise of the plane woke the snake. It put its head out and looked into the pilot’s room. The pilot saw the snake and was greatly afraid. He was very afraid that the snake would bite him so he could not control the plane, and the plane started to swing strongly from side to side.
