  • Seventy million years ago, a great inland sea disappeared and the Rocky Mountains emerged from the seafloor.
  • Sixty million years ago, they reached their peak height, twice what it is today.
  • Then for millions of years, the Rockies slowly eroded away to half their original height until 3 million years ago,
  • another dramatic chapter in their story began that would transform them into the Mountains we know today.
  • Geologist and photographer Bob Anderson takes to the air.
  • He is looking for clues that will tell him how the Mountains have evolved.
  • First he flies over Boulder Canyon in the Colorado Rockies.
  • It is an area that has remained almost unchanged over millions of years.
  • " So this is Boulder Canyon we are flying up right now. And you can see how the river has in size maybe a few hundred feet down into otherwise relatively rolling terrain.
  • " The mountain peaks that existed on the young Rocky Mountains were rounded off as rivers and streams eroded the rock.
  • " It's this rolling terrain that the landscape look like in the aftermath of the mountain building event that ended about 50 million years ago.
  • " But as Anderson climbs higher to Longs Peak in the Rocky Mountain National Park, the terrain changes.
  • Instead of rolling hills, there are rugged mountains with steep and jagged cliffs.
  • It's evidence that another force has been at work.
  • The most famous of these cliffs is the Diamond.
  • Named for its shape, it's a vertical wall with a sheer 900 foot drop.
  • The summit about 45,000 square feet is the same size as a football field.
  • " Well, we are flying beside, ur, Longs Peak, one of the biggest climbing challenges in the Rockies.
  • For a century, it's been a climbing Mecca. It's a gorgeous, intact piece of rock.
  • " This awesome wall is the most difficult climb in the whole of the Rockies.
  • And since it was officially open to climbers in 1960, has claimed over 50 lives.

句子讲解:

1. The mountain peaks that existed on the young Rocky Mountains were rounded off as rivers and streams eroded the rock.

【结构简析】"rounded" 是形容词“圆形的;丰满的;全面的”的意思。在这里“off ”是“离开;脱落”的意思,所以就可以翻译成瘦,因为是山峰的形状,所以可以译成“瘦骨嶙峋”。

【参考译文】 在落基山脉的山峰显得那么的瘦骨嶙峋,原因是河流和溪流不停地侵蚀着这里的岩石。

2. Instead of rolling hills, there are rugged mountains with steep and jagged cliffs.

【结构简析】"rolling hills"变成了"rugged mountain","instead of "后面接比较的成分。

【参考译文】这儿不是连绵起伏的丘陵,而是陡峭的悬崖和锯齿状的峭壁。
