过了一会儿，摩根一家人坐的观光车在路上拐了个急弯。

Within, the ceilings were corrugated with heavy oaken beams, and the uneven floors sagged into sharp curves.

在里面，天花板由沉重的橡木横梁组成波纹状， 不平坦的地板下垂成尖锐的曲线。

A stretch of it has a 27 degree grade with sharp curves because paving it straight up and down in 1922 would have made it too steep for the cars of that era to climb.

其中一段有27度的坡度和尖锐的曲线，因为在1922年把它上下铺平会使那个时代的汽车爬不上去。
