答案　是E，　

C　中　have been dated 在含义上等于to be , 意义是重复的。

I will chose C

作者: wzhyan 时间: 2005-12-3 13:56

我选C

E: have been dated at 3.47 billion years old and thus are

中这种表达合适吗

作者: jxjiao 时间: 2005-12-4 02:52

好象有个知识点:现在发现已经过去的事情用to be更好,(og 10th version应该有道题目,believed to be of...)

类似..estimated to be..

讨论

我选E,GWD-13-Q28中关于date有类似的用法date at.

GWD-13-Q28:

Fossils of the arm of a sloth found in Puerto Rico in 1991, and dated at 34 million years old, made it the earliest known mammal of the Greater Antilles islands.

A. sloth found in Puerto Rico in 1991, and dated at 34 million years old, made it the earliest known mammal of

B. sloth, that they found in Puerto Rico in 1991, has been dated at 34 million years old, thus making it the earliest mammal known on

C. sloth that was found in Puerto Rico in 1991, was dated at 34 million years old, making this the earliest known mammal of

D. sloth, found in Puerto Rico in 1991, have been dated at 34 million years old, making the sloth the earliest known mammal on

E. sloth which, found in Puerto Rico in 1991, was dated at 34 million years old, made the sloth the earliest known mammal of D

这个在GMAT prep出现了，选C

作者: lazyratcn 时间: 2006-11-29 06:29

楼上的肯定吗，PREP选C？

作者: rio 时间: 2006-12-3 18:46

时隔一年终有定论

况且很简单的一个问题就是：dated at XXyear可以，但后面还有一个old阿

所以只能是dated to be xx year old

作者: rio 时间: 2006-12-3 18:48

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？

作者: chamcham 时间: 2007-6-22 15:11

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？

作者: wsdoll 时间: 2007-10-4 11:24
prep 没有这道题

作者: hollygrail 时间: 2007-12-11 00:37

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.
