雨后，小径的坑洼处形成了一小滩水。

After the rain, a small ___pool of water had formed in the depression on the path.

小心别踩到车库地板上那摊油渍。

Be careful not to step in that oily ___pool on the garage floor.

孩子们被退潮后留在海螺里的那一点点水吸引住了。

The children were fascinated by the tiny ___pool left in the seashell by the retreating tide.
