High mountains and low valleys

高山───mountain;低谷───Low ebb

After hiking all day we finally reached the uppermost part of the mountain.───徒步走了一整天,我们终于爬到了山顶.

The outline of the mountain in the distance is dim.───远处山脉的轮廓隐隐约约.

He fell behind when we were climbing the mountain.───我们爬山时,他掉队了.

This mountain is lofty.───这座山极高.

The mountaineers did not begin to come down the mountain till they had reached the top.───登山者们登上顶峰后才开始下来.

Every bit of Huangshan Mountain scenery is worth painting.───黄山山景,处处可以入画.

We're going down a mountain.───我们向山下走去。

A mountain of dirty clothes is to be washed.───有成堆的脏衣服要洗.

These shoes won't do as mountain climbing.

They climbed up the mountain and reached the summit.

There is still snow on the mountain tops.

They hollowed out a tunnel through the mountain.

We retreated back down the mountain.
