I think I'll give up that public speaking course and join a hiking club – to learn how to walk the walk.

我想我会放弃那个公共演讲课程，加入一个徒步旅行俱乐部——去学习如何走路。

If you want to, for example, play golf at a public golf course – a government-owned golf course in Los Angeles – you have to pay a fee.

例如，如果您想在公共高尔夫球场（洛杉矶政府拥有的高尔夫球场）打高尔夫球， 则必须付费。
