英语语法分析

Water gradually escapes by seepage through the ground.

水逐渐从地上渗走了。

《牛津词典》

If the former are greater, the lake is a surface-water-dominated lake; if the latter, it is a seepage-dominated lake.

如果前者较大，这个湖就是一个以表层水为主的湖泊；如果是后者，则是一个以渗漏为主的湖泊。

Note the word "net" measuring the actual amounts of groundwater seepage into the lake and out of the lake is a much more complicated matter than merely inferring their difference.

注意“净值”这一词：测量地下水渗入并且渗出湖水的实际水量比仅仅推断出它们的差异要复杂得多。
