请nn们帮忙：OG10-17 新问一个分词的小问题

bobo19790111

17. Native American burial sites dating back 5,000 years indicate that the residents of Maine at that time were part of a widespread culture of Algonquian-speaking people.

(A)  were part of a widespread culture of Algonquian-speaking people

(B)   had been part of a widespread culture of people who were Algonquian-speaking

(C)  were people who were part of a widespread culture that was Algonquian-speaking

(D)  had been people who were part of a widespread culture that was Algonquian-speaking

(E)   were a people which had been part of a wide­spread, Algonquian-speaking culture

题目中的dating back，为什么是dating现代分词哪而不是dated back？是因为date表示不及物动词的意思？

多谢指教~~~~~

because it is that Native American burial sites date back.....not they are dated back.....

eg.......has found evidence of forest fires dating back thousands of years

看了解释，还是不理解，这个分词不同用法的区别在哪里。

能把这句话翻译一下吗？不明白句意。

谢谢！

可追溯到5000年前的美洲印第安人的墓葬显示缅因州的居民在那时属于 广泛分布的阿尔贡金语系文化的一部分.

dating分词作状语，修饰主语美洲印第安人的墓葬

看了好多句型，date  back作为追溯年代就是不及物动词，所以是dating back。
