As he sat on the grass and looked across the river, a dark hole in the bank opposite, just above the water's edge, caught his eye, and dreamily he fell to considering what a nice snug dwelling-place it would make for an animal with few wants and fond of a bijou riverside residence, above flood level and remote from noise and dust.

他坐在草地上，朝着河那边张望时，忽见对岸有个黑黑的洞口，恰好在水面上边。他梦悠悠地想，要是一只动物要求不过高，只想有一处小巧玲珑的河边住宅，涨潮时淹不着，又远离尘嚣，这个住所倒是满舒适的。
