坑的英文怎么说？

Pit has long been one of the most important objects in human life. In ancient times, for military and defensive purposes, pits were usually dug in the ground to build fortifications, trenches and clan graves. In addition, because of its large capacity, many pits are also used to store dry food, water and fuel to avoid floods or serve as a refuge in natural disasters or emergencies.

In addition, the pit may also be formed by other external factors such as ground subsidence due to underground mining of ore and erosion caused by rainwater.
