They had not gone far before they came to a place where the ground became rough and there were rocks all about and little hills up and little hills down.

他们没走多远就来到一个地势高低不平，到处都是岩石，山峦起伏的地方。

And of course in those days I had a bike, too, and I remember I used to push it up this very long hill near our house and then Vd get on and ride down as fast as I could go.

当然，那时候我也有一辆自行车， 我记得我曾经把它推上我们家附近这座很长的山坡， 然后 Vd 上车， 尽可能快地骑下来。

I turned in and followed a graveled road around the shoulder of a hill, up a gentle slope, over a ridge and down the other side into a shallow valley. It was hot in the valley, ten or fifteen degrees hotter than on the highway.

我转身沿着一条碎石路绕过山肩，爬上缓坡，越过山脊，从另一边下到一个浅谷。山谷里很热，比公路上还要热十到十五度。
