In the morning, the boss came and yelled all along the shore -- thus the name longshore.

早上，老板来了，沿岸大喊大叫——因此得名longshore。

Consider the longshore workers, those who load and unload ships.

那些装卸码头工人。

You can swim left or right but you do not want to swim against the longshore current as it can pull you back into the offshore flowing rip.

你可以向左或向右游，但是不要逆着它游，因为它可能会把你拉回到离岸流激浪中。
