标题: OG-12 78做题有点晕了
78. 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
A 怎么错了？答案B 但为什么是HAS？fossils是复数啊，应该是have吧

答案是D吧，麻烦下次划个线
D:主语是fossils 当然用have
A:it 指代不对 made的用法也错了，应该在这里做结果状语

啊晕，不好意思啊的确答案D

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

问下大家， found 在正确选项是就近修饰sloth，还是修饰句子主语 fossils。

两个都讲得通~
偏爱Fossils，因为是核心词，经常被跳跃指代

PS 你的签名。。。别想不开取舍很痛苦丫~

应该是fossils, 你把found in Puerto Rico in 1991跟第一句换个位子就很明显了。

E选项中的which是修饰sloth还是fossils?og 的解释说e选项的singular verb 和plural subject 不符，但为什么不能理解是修饰sloth，而出错的应该是在后面的made?

今天刚做了这道题，虽然做错了，但是我还是来尝试回答下这道题。
非牛，可能说的有问题，轻拍~

再把E选项还原一遍，我们可以得到：
Fossils of the arm of a sloth which, found in Puerto Rico in 1991, was dated at 34 million years old, made the sloth the earliest known mammal of the Greater Antilles Islands.

按照Manhattan 中对which用法的说明：

Use WHICH only to refer to the nounimmediately preceding it—never to refer to an entire clause.

那么这里which修饰的就是sloth..

所以我感觉有时候OG里面对答案的解释也是有问题的...

比如这个选项里面，去掉两个逗号之间的found就是：
Fossils of the arm of a sloth which was dated at 34 million years old, made the sloth the earliest known mammal of the Greater Antilles Islands.
那么这个结构就是有问题的，但是OG并没有这么解释...

看了下发现自己说的很乱，您看着理解吧..
欢迎拍砖

这里的A选项应该还有一个问题就是那个and dated让dated也修饰sloth了本来dated应该跟fossil的吧

请问一下， that和which都是修饰近邻的词对吗？例如此题2B，抛开逗号和they指代的问题，是修饰sloth的对吗？？

还原C选项，fossils of the arm of a sloth that was found in Puerto Rico in 1991, was dated at 34 million years old, making this the earliest known mammal of the Greater Antilles Islands.

that紧跟着sloth应该理解为修饰sloth 即，sloth应为was found的主语，所以没有问题。但主句逻辑主语还是fossils，所以was应该改为were就对了吧？

this 如果指代a sloth的话，逻辑上有问题，会变成一个sloth是最早发现的生物！

不知道理解是否有问题，欢饮讨论

对了还有一个问题，不知道为什么答案选择用现在完成时态，date难道不是瞬间完成的事情嘛？即为瞬间动词，可以用作完成时态强调对现在的影响吗？

我也有这个困惑...

Ron在http://www.manhattanprep.com/gmat/forums/sc-fossils-of-the-arm-t7830.html中解释了这个问题，但我还不是特别懂，他说
n describing a past event that is no longer occurring, we can use either the present perfect or the simple past. the difference between the two is one of semantic meaning:

* the present perfect (has/have VERBed) is used if the event still has a tangible impact or influence on, or relevance to, the present state of affairs.

* the simple past is used if the event does NOT have any tangible impact/influence/relevance in the present.

note that, in many cases, either of these tenses could be used to describe exactly the same event in exactly the same timeframe!
here's an example: imagine that you are talking to a guy, at a bar, who has had 3 marriages. (he is currently divorced.)

if the two of you are actually talking about marriage, he will probably say "i have been married three times".

if the two of you are NOT directly talking about marriage or its consequences -- for instance, he is just enumerating members of his family -- he will probably say "i was married three times".

both of these are correct -- in terms of both grammar and semantics.

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).

那说明be dated at这个动作发生在过去吗？为什么呢？

另外我觉得如果理解成这个句子想强调“已经有34m yrs那么久了”可能更好接受点？

求大神们指点

date是发生在过去，但是强调对现在的影响即后面的making the sloth the earliest什么什么

谢谢你的回答.

回过头来重新准备gmat
我觉得根据语义 "which _ dated at 34 million years old" 应该修饰 fossils, 而不应该修饰 "a sloth", 所有用 "which was dated" 就不太合适.
