广播电视英语短句 第 290 课：找到粘土-5

You can usually find good clay in low areas of islands or land, especially if volcanoes helped form the land. 你通常可以在岛屿和内陆的一些低洼处找到优质的粘土，特别是因火山影响而形成的陆地。

Clay often exists in fields covered with some water. 粘土通常也存在于那些被一些水覆盖的区域。

The clay will be found about one meter below the ground. 可能在地下 1 米 处左右发现粘土。

River banks often also have clay about one meter or less under the surface. 河岸表层下大约1米 ，或1米不到的地方也能发现粘土。

You can recognize clay because it is very shiny when it is wet. 当粘土潮湿时会反光，届时你会容易就认出它。
