急请教GWD31-28

rio

另外我觉得GWD13中出现过dated at 也不能说明他就一定是正确的

因为在那道题里面只有dated at

就像还有很多道题compared to都作了正确答案，因为选项里没有compared with

但这并不是说compared to优于compared with

终于有定论啦~~但想请教一下，date at和date to be的用法是固定用法吗？

This is great, but I did see some examples in nytimes saying "be dated at two years old"

以下是引用redhot99在2006-10-3 9:19:00的发言：

这个在GMAT prep出现了，选C

prep里面没找到啊，第几题啊？第一套还是第二套的？

prep 没有这道题

已确认prep没这道题,prep里也没有date的考点.be dated at XXX years old应该是没问题的用法.在NY times上用have been dated at搜到一堆,用have been dated to be搜,没有.

NY Times
STONE tools found in the desiccated fossil fields of Ethiopia have been dated at 2.6 million years old, making them the earliest known artifacts created by humans or their direct ancestors.
