某日我路过一条盛极而衰的河道，它曾经是热闹的港口，但随着河流的干涸，周边的城镇逐渐消亡，只剩下沙土、砂砾在河道上。

I passed by a river which grand and important but now increasingly dry. It used to be a lively port, However, as the river dried up, the towns along it gradually disappeared, the inhabitants dispersed, and only sand and gravel remained in the riverbed.
