First, there's the gastrointestinal tract, a twisting channel that transports your food and has an internal surface area of between 30 and 40 square meters, enough to cover half a badminton court.

首先是胃肠道，这是一条输送食物的扭曲通道，内表面积在 30 到 40 平方米之间，足以覆盖半个羽毛球场。

At present, our station does not have an internal seating area for passengers, so they are forced to wait for their trains outside on the platforms, which can be particularly unpleasant during the winter.

目前，我们的车站没有供乘客使用的内部座位区，因此他们不得不在外面的站台上等车，这在冬天尤其令人不快。
