At Birch, boardgames occupy every horizontal surface, ready to draw out the procrastinator in you.

桦木酒店的每一个台面上都占据着棋盘游戏，随时准备诱发你的拖延症。

But here's the interesting bit: bats never smashed into a smooth horizontal surface.

蝙蝠来不会撞到光滑的水平面。

It's usually up because it's in contact with a horizontal surface.

它通常是向上的，因为它与水平表面接触。

So " They were driving ON the road" . Now again, we know it's ON because the road is a horizontal flat surface.

所“们在路上开车” . 现在，我们知道它是打开的， 因为道路是水平的平坦表面。
