People set up the sarsens at Stonehenge over 4,000 years ago.

在4000多年前，人们将撒森岩放置在巨石阵上。

Stonehenge was constructed with giant sarsen stones, sandstone blocks that are common in southern England.

建造巨石阵的石材是萨尔森石，石块在英国南部地区相当常见。

It was similar to sandstone found at West Woods and all but two of the Stonehenge sarsens.

一石块与在西伍兹和巨石阵中发现的砂岩相似，有两个例外。

The largest stones, called sarsens, measure up to 30 feet or 9 meters tall and weigh an average of 25 tons.

其中最大的石头，被称为砂岩残块，据测量有 30 尺，也就是 9 米那么高，平有 25 那么重。

But what happened to that core? An employee from the company that helped repair the sarsen held onto it.

那被取出的岩心去哪里了？当时有一家公司为修复萨尔森石提供帮助，正是家公司的一名雇员保留了一块岩心。

Stonehenge was used as a cemetery from its inception just after 3,000 BC until well after the large sarsen stones went up around 2,500 BC.

公元前3000年，巨石阵从一开始就被用作公墓直到公元前2500左右，羊背石得以建造。

Although they are smaller than the massive sarsens, the bluestones still weigh an average of 4 tons each, and archaeologists are baffled as to how they were transported so far without modern technology—or even the wheel!

尽管青石比巨大的砂岩残块要小，但每块仍平重达 4 ，考古学家非常疑惑人们是怎样运输了如此远的距离，在没有现代工具甚至没有轮子的情况下！
