请教各位先进, 在Unforgettable记忆神探第3季第5集A Moveable Feast里面, 因为船爆炸了,2个警察Al和Charles在救人和打捞证据。 Al: There's a big chunk of the stern going under there. Charles: Damn it. Al: These flood currents are sweeping away our evidence, huh? Charles: What's a leg like you know about flood currents? Al: I used to go fishing up on Lake Ontario. 请问这里"What's a leg like..."的意思是什么? 我查了字典和google,但是都没有结果。 谢谢。 附上上下文连结: https://reurl.cc/akzGkQ
