turn over in bed

I turn over in bed.

我辗转于床上。

People from the other tables had gone to bed: in the sudden silence we distinctly heard the deep roar of a serac, like the bones of a giant trying in vain to turn over in his bed of rock.

坐在别的桌子边上的那些人都去睡觉了：突然这一沉静下来，我们清楚地听到冰柱低沉的哄叫声，冰柱像个巨大的骨头徒劳地想在岩石层上滚动。

The patient can comfortably turn over towards both sides and in a supine gesture, and is always on the central axis of the bed body.

患者能舒适地完成两侧与仰卧姿势的翻身。并始终处于床身的中轴线上。
