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

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.

蝙蝠从来不会撞光滑的水平面。

A lot of the horizontal surfaces are covered with bogs.

许多水平表面都被沼泽覆盖了。

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。

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

所以“他们正在路上行驶”。现在再次强调，我们知道是“在… … 上”是因为路是一个水平的平面。
