First of all, we planned a horizontal opening to the garden in such a way that the passenger at bus stop across a street is not visible.

首先，住宅面向花园并与之处于同一水平位置，从住宅内无法看到街道对面的公交车站。

The bus goes over a bump. Its velocity is initial horizontal but it acquires a small upwards component as it rises, then a downwards component, then back to being purely horizontal.

当汽车驶过一个小包时，上坡时原本是水平的速度获得了一个小小的向上的分量，下坡时又有了一个向下的分量，然后回归水平。
