The requested the rights to stroll and to do the breast stroke after work.

他们要求工作之余去散步和俯游的权利。

They're naturally buoyant and can actually do the breast stroke like humans, which is really just another great evolutionary adaptation because rainforests are prone to seasonal flooding.

它们天生就有浮力，实际上可以像人类一样进行蛙泳，这实际上是另一种伟大的进化适应，因为雨林容易受到季节性洪水的侵袭。

Now, you're not allowed to use swimming strokes, and no breast stroke, no front crawl, no back stroke, you kind of just have to sort of push your way through.

不允许你使用泳姿，没有蛙泳，没有自由泳，没有仰泳，你只能通过某种方式推动前进。
