Some of the smaller stones, called bluestones, are believed to have been brought from Wales, more than 140 miles or 225 kilometers away.

其中一些比较小石头，称作青石，被认为来自威尔士，运送超过了 140 英里，也就是 225 千米距离。

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!

尽管青石比巨大砂岩残要小，但每均重达 4 吨，考古家非常疑惑人们是怎样运输了如此远距离，在没有现代工具甚至没有轮子情况下！

Several hundred years later, it is thought, Stonehenge's builders hoisted an estimated 80 bluestones, 43 of which remain today, into standing positions and placed them in either a horseshoe or circular formation.

据认为，数百年后，巨石阵建造者将大约 80 青石吊起，并以马蹄形或圆形形式竖立起来，其中 43 至今保留下来。
