Bill liked planes very much. At the         of thirty-five, he bought a small plane and learned to           /flai/it. He soon           (变得) good at it and made his plane do all k          of tricks(特技) in the sky.
One day, Bill           （邀请）his good friend Mark to fly with him. Mark thought, “I have traveled in a       / bɪg / plane several times, but I have never been in a        one, so I’ll go.” They went up, and Bill flew around        half an hour and did all kinds of tricks in the air. When they came down again, Mark was very        /ɡlæd/ to be back       （安全地）and he said to his friend in a trembling（颤抖的）voice，“Well, Bill, thank you for those two trips in your plane today.”
Hearing this, Bill was very surprised and said, “Two trips?”
“Yes, my first and my last.” answered Mark.
