shallow中等

We can offer them a visit to Blackwater National Wildlife Refuge in Dorchester County where bald eagles fly over tidal marshes so shallow you could not paddle a boat across them but teaming with aquatic life.

我们可以邀请他们参观多切斯特县的布莱克沃特国家野生动物保护区，在那里，白头海雕飞翔在潮汐沼泽上空，这些沼泽浅得连船都划不过去，却充满了水生生物。

The shallows provide homes for hundreds of species while storing floodwaters, filtering pollutants from water, and protecting nearby communities from potentially destructive storm surges.

这片浅水区为数百种物种提供了栖息地，同时还能蓄积洪水、过滤水中污染物，并保护附近社区免受可能具有破坏性的风暴潮侵袭。
