I had done no skiing, no climbing, and no hiking.

我从未滑过雪、攀过岩和徒步旅行过。

I have no climbing shoes.

我没有登山鞋。

Does the sign over there mean 'No climbing'? Yes, it does.

那边的标志意味着禁止攀爬吗？是的。

But I had no climbing shoes and the only things that could serve were Japhy's tennis sneakers, old but firm.

但我没有攀山鞋，唯一能应用的，就是阿尔瓦那双网球运动鞋，陈旧但牢固的。

I went round to see if it was open on any side, but saw it was not, and that there was no climbing up to the top, as it was so smooth.

我绕着它看看是否那边能打开，但是没有看到，它太光滑了，不能爬到上面去。
