prep 94 再问~

The decline of the mountain yellow-legged frog in the high reaches of the Sierra Nevada has

become severe enough for the United States Fish and Wildlife Service quite possibly to list it as an

endangered species in the near future.

(A) severe enough for the United States Fish and Wildlife Service quite possibly to list it

(B) severe enough so that the United States Fish and Wildlife Service could well list them

(C) severe enough for it quite possibly to be listed by the United States Fish and Wildlife Service

(D) so severe that the United States Fish and Wildlife Service could well list it

(E) so severe that they could well be listed by the United States Fish and Wildlife Service
答案木有问题，是D。我就想问问，这个D中的it，prep笔记的的解释是it指代mountain yellow-legged frog;
但是为什么不会产生指代decline的歧义呢？我之所以会有这个问题是因为og12 的78题，如下：

og12 78Fossils of the arm of a sloth found in puerto tico 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
D)sloth,found in Puerto Rico in 1991, have been dated at 34 million years old, making the sloth the earliest known mammal on



答案是D，A错的原因是it只能指代fossils，非sloth，因为显然fossils是这个所有格结构中的核心词。所以在后文中要重述一次。大家不觉得很奇怪么？在这个地方fossils是复数，sloth是单数，用it指代会产生的歧义程度显然没有前一题decline和frog都是单数造成的歧义大。但是在og里面都是不允许的，为什么在prep里面又没有这样的混乱了呢？请大侠NN斑竹啥的帮忙看看吧。谢谢了。

同意楼主观点，其实这里的it是会产生指代不清的问题。
OG78：根据OG的官方解释：原句的主语是fossils，而非sloth，因此it无对应指代的对象。
PREP94，与OG78是几乎完全相同的结构，句子主语也不是mountain yellow-legged frog，而是decine.
我也觉得这道PREP题目出得不是很完美，但是楼主也别太认真，毕竟选出正确答案才是我们的最终目的。

不同意ls的观点，因为语法不仅仅考的是语法，句子意思的逻辑合理也很重要，lz注意看it后面的部分， as an endangered species in the near future.             it显然不能指代decline。

同意；
做语法的时候要主语未划线部分的修饰语，像这道题后面有明确的解释说明，就可以理解为是对it的解释，这样读句子的时候就不会误认为指代decline了；

啊，多谢楼上的2位指教，又犯了那个老错误了，看题只看一部分。

prep pack 3已经将D里面的”it“ 改成“the animal" 了
