whirligig

The little boy spun the wooden whirligig on the floor until it slowed down and stopped.

小男孩在地板上转动木陀螺，直到它慢慢停下来。

A metal whirligig on the porch spins cheerfully whenever the breeze blows.

每当微风吹过，门廊上的金属风车装饰就愉快地旋转起来。

The children queued twice to ride the whirligig at the summer fair.

孩子们在夏日集市上排了两次队，就为坐那旋转木马。
