“积水”常见的英文表达是 standing water 或 ponded water。
standing water:强调水静止不动、积聚在某个地方的状态,是较为常用和通用的表达。例如:The heavy rain caused standing water in the streets.(大雨导致街道上出现了积水。)
ponded water:更侧重于描述像在池塘里那样积聚起来的水,在特定语境下,比如涉及工程、水利等领域讨论积水问题时也可能会用到。例如:After the storm, there was ponded water in the construction site.(暴风雨过后,建筑工地出现了积水。)
