When George was thirty-five, he bought a small plane and learned to fly it. He soon became very good and made his plane do all kinds of tricks(特技). George had a friend. His name was Mark. One day George invited Mark to take Mark up in his plane. Mark thought, 'I've travelled in a big plane several times, but I've never been in a small one, so I'll go.' They went up, and George flew around for half an hour and did all kinds of tricks in the air. When they came down again, Mark was very glad to be back safely, and he said to his friend in a shaking（颤抖）voice, 'Well, George, thank you very much for those two trips in your plane.' George was very surprised and said, 'Two trips?' 'Yes, my first and my last,' answered Mark. 判断正误，正确的写A，错误的写B 小题1:George was good at flying the plane. 小题2:George invited Mark to take his plane. 小题3:Mark didn’t want to take George’s plane. 小题4:Mark felt very happy when he was in the air. 小题5:Mark had two trips in George’s plane.
