标题: OG13 81 D现在完成时 RON大神解释的内容求解释
贴上RON大神关于D选项中 have been found in 的解释，求大神帮忙理解下，为啥说用过去式不合适？

in the example at hand, the present perfect probably makes a little bit more sense, since the findings clearly have direct relevance to the situation being discussed at present. however, it would certainly not be incorrect to use the simple past (although that usage would suggest that the findings no longer have relevance, possibly because they have been superseded by some more recent findings).

非常感谢·～～～

D 里面哪里有have been found in。。。

是说have been dated at吗？我感觉这个话根据logical predication可以判断date at 这句是谓语部分，根据主谓一致可以排除3个选项，然后排除A。。。我个人的理解，轻拍砖。。。。

楼主，ron说“it would certainly not be incorrect to use the simple past ”，这not incorrect难道不是correct的意思？过去式也可以啊？你是不是看错了？

LZ想表达的意思应该完成时吧，D最主要的错误是，have been found in 不是一个modifier啊，而是一个V，应该用having been 才对。
