earthworm

Earthworms comminute the mineral fraction of soils.

粉碎土壤中的无机碎片。

When the earthworm appears in the morning,the sun will shine brightly.

早出太阳,晚迎雨汤。

Earthworms burrow deep into the subsoil.

深深地钻进底土。

Thirty-four years ago only a few earthworms, if any, could be found in a spadeful of his soil.

34年前，这里一铲子的泥土里就算有，也寥寥可数。
