The traffic in the city is chaotic in the rush hour.

在上下班高峰时间，城市的交通混乱不堪。

I left early to avoid the rush hour.

我早早动身以避开交通高峰时刻。

They run extra trains during the rush hour.

他们在车流高峰期加开了列车。

The explosive device was timed to go off at the rush hour.

该爆炸装置定在交通高峰时间爆炸。

During the evening rush hour it was often solid with vehicles.

在傍晚高峰期，车辆经常堵得水泄不通。
