　　這種寂靜深不可測，令人不知所措。

　　Day are coloured bubbles that float upon the surface of fathomless night.

　　日是五彩繽紛的氣泡，漂浮在無盡的夜的表面。

　　He did really fathomless that nobody knew he earned a lot of money.

　　他可真是藏龍臥虎：賺大錢，可誰都不知道。

　　I know of a fathomless well.

　　我知道一口深不可測的井。

　　She looked at him with calm, fathomless eyes.

　　她用她那雙平靜而深不可測的眼睛打量著他。
