马莉会的可不只是狗刨式游泳，这只金色的寻回犬还喜欢潜水，可以直游到这个深七英尺深水池的底部。

Nobody teaches you how to do the doggy- paddle.

没有人教你如何游狗刨式。

You'll need to master that first, otherwise your swimming will always be like the doggy-paddle. You'll splash water around a lot, with very little result.

首先你必须精通换气，否则你会游得像狗刨式一样，溅起许多水花却只得到一点效果。

I can't even do the doggy-paddle.

我连狗刨式也不会。
