戴维与其他几个人上了一部电梯。电梯开始移动了，他盯着电梯天花板，那里有一个小风扇缓慢的旋转。 “这是惊人的，”他对其他人说，“这样一个小风扇可以把所有这些人升上去！” David was on a elevator with several other people. As the elevator moved up, he stared at the small fan revolving slowly in the elevator ceiling. "It's amazing," he said to the other people, "that such a small fan could lift all these people!" |
