在一些地方，高峰期的少量过路费和一些公汽就足以保障交通在不确定情况下的平稳运行。

In some places, a small toll at rush hour and a few buses will be enough to keep traffic running smoothly indefinitely.

今天，在去上班的公汽上，一位老妇坐在我旁边，在离单位还有一半路程的时候，她睡着了并且把头靠在我的肩上。

Today, I took the bus to work and a sweet old lady got on after me and sat next to me. Halfway to work, she fell asleep and her head was on my shoulder.
