The penitentiary was roofless and floorless , only the walls standing .

监狱没有屋顶也没有地板，只剩下墙壁屹立著。

We use a floorless scott tent as our outhouse , which helps provide a shelter to make this basic function much more pleasant , especially when the wind is howling and the snow is blowing .

我们用无底的斯格特帐篷作为户外厕所，它提供的庇护所使得这一基本的机能需求更令人愉悦，特别是碰上刮风下雪天的时候。
