1. Winds whipped the piled leaves into churning masses; a car stuck in the churned-up mud.
    秋风吹动成堆的树叶打着旋；陷在泥泞里旋转着轮子的汽车。

2. The churned-up water frothed alongside with a confused murmur.
    拍出的补水frothed连同混乱的杂音。

3. A dead axle on a carriage or wagon that has terminal spindles on which the wheel revolve. winds whipped the piled leaves into churning masses; a car stuck in the churned-up mud.
    马车上或货车上有车轮围着旋转的末端心轴的从动轴。秋风吹动成堆的树叶打着旋；陷在泥泞里旋转着轮子的汽车。
