It is believed that this phrase has something to do with boats that sometimes get stranded on beaches due to shifting sea levels.這個俚語的來源于船有關，有時候船會因為海面的波動而被擱淺在海岸上。 For instance, if a boat is left near the shore during high tides, then it is at risk of be grounded later on.比如，如果一條船在漲潮時停在了海岸附近，那么就有可能被擱淺 Why? Because water levels can decrease throughout the day. 這是為什么呢？因為水平面會降低。So while a boat may have been left on the coast in high waters, in just a few hours, the sea level can fluctuate in that area, leaving the boat stranded on land. 船在漲潮時被推到了岸邊，不一會，海平面開始波動，潮水退去的時候船就被擱淺了。Indeed, the boat was abandoned by the water, it was left 'high and dry. 這個時候，船就被潮水遺棄，就會被“高高地并且干燥地”留在岸邊；
