PS：The Great Lakes 五大湖区
vessel 船 舰
The Great Lakes Laboratory employed a licensed boat captain for its research vessel. It was common knowledge that the captain couldn't swim. When newcomers learned of this, they would often approach him about it, "Is it true? You, a boat captain, can't swim?" "No, I can't!" he replied. "Can pilots fly?"
五大湖实验室雇用一位有执照的船长驾驶研究用的船。大家都知道这个船长不会游泳。当新来的人知道这件事以后，他们常常会去问他：“这是真的吗？身为船长你不会游泳？”他回答说：“对，我不会！飞行员会飞吗？”
