there is one怎么会是指时间啊其实will fail to detect a condition when...and indicate sth when... 我感觉更对称一些.
我想indicate its presence 不如indicate that it is present 是因为 最后的 when it is not 后承前省略了present, 用indicate that it is present when it is not 比较通.
一般语法书上都认为，一个代词前面有n个语法上可指代对象是错的，但ETS好像不这样认为。ETS认为逻辑意思指代清晰即可。本题按一般语法原理是错的，因为有2个语法上可指代对象。不过从逻辑意思上，指代是清晰的。
什么是逻辑上不清晰呢：My mum told my aunt that she should go there. 在这个单独的句子里，这个she就是无法判定指代对象，指代谁都可以理解。
但是本题只有指代condition才可以理解。
继续请教关于referent和logical referent.
我认为，从语法上讲，choice A和B是有referent的，只是这个referent不合逻辑。类似例子有OG 43 choice B.
43. In the minds of many people living in
(B) before there was
OG在43题的解释说:
In B, it has no logical referent, because the previous clause describes a time when there was no
同理我们可以认为83题的A/B也是没有logical referent. 可是83题的解释却是
In choices A and B, the phrase indicate that there is one does not grammatically fit with when it is not because it has no referent.
一般OG说没有referent, 是说没有语法上的指代对象; 说没有logical refernt，是说有语法上的指代对象，但是逻辑不对。
我的问题是，83里的解释为什么说no referent, 而不是no logical referent? 是OG漏了logical? 还是我分析错误钻牛角尖了？NN请指教啊!!!
再贴一遍题目和解释，看得方便些。
43. In the minds of many people living in
(A) before
(B) before there was
(C) it was the antipodes that was
(D)
(E)
Choice A is best, for A alone makes clear that the land now known as
83. Any medical test will sometimes fail to detect a condition when it is present and indicate that there is one when it is not.
(A) a condition when it is present and indicate that there is one
(B) when a condition is present and indicate that there is one
(C) a condition when it is present and indicate that it is present
(D) when a condition is present and indicate its presence（C）
(E) the presence of a condition when it is there and indicate its presence
Only choice C, the best answer, produces a sentence in which every pronoun it refers clearly and logically to the noun condition. In choices A and B, the phrase indicate that there is one does not grammatically fit with when it is not because it has no referent. Choices B and D are imprecise in saying that a test will fail to detect when a condition is present, since the issue is the presence and not the timing of the condition. Further, its presence in D leaves the it in when it is not without a logical referent: it must refer to condition, not presence. Choice E repeats this error; also, the presence... when it is there is imprecise and redundant.
A B 两个选项代入原文后是 and indicate that there is one when it is not.
忘记and前边的话，因为离开when it is not 中的it太远了。 这样，是不是就发现这个it 没有referent？
请NN指教我说的对吗？
To rhod:我有和你一样的问题:it has no referent?Andrea625的解释我也想过了, 但如果按这种想法, 正确答案:indicate that it is present when it is not. 其中的it 也不好找referent.
我现在猜测: 是不是one特殊, 不能做别的词的先行词?
你有结果了吗?请告知!

很糊涂！
同意rhod. 像43 题一样因为 "it" 就近指代 "there is one"，而"there is one" 是指时间，所以不能被it 指的。

there is one怎么会是指时间啊
另外我觉得这题和OG43不大一样
请看
43. In the minds of many people living in
(B) before there was
OG在43题的解释说:
In B, it has no logical referent, because the previous clause describes a time when there was no
这里的it是有referent的,指代的是前面的Australia,但是因为B的意思是before there was
本人感觉此题ETS解释肯定有问题，这里明明it 指代condition. 而此题A中的最大问题在于 when it is not的省略问题.因为前面是there is one（有这么一种condition）, 所以后面的when it is not感觉不知所云，连起来就成了 there is one (condition) when it is not(什么意思？？？）,not后不知省略什么。 而答案C因为前面有indicate that it is present,所以后面when it is not后明显省略了present,补全了就是indicate that it is present when it is not present.
不知理解是否有理请大虾们指正。谢谢。

这与我的想法不谋而合. 而且我越想越有道理.不知大家意见如何?
能不能这样理解：
......and indicate that there is one when it is not.
one指代condition（疾病），泛指。“当没有病的时候，显示有病（泛指）。”所以从逻辑上讲，前一个“病”也是泛指疾病，不是特指。而it是一个特指的代词，没有办法泛指，句子中也没有这样的名词，所以og说 it 没有可指代对象。
I agree with ca3ltoys.

但是本题只有指代condition才可以理解。
我一直困惑的是,这种逻辑判断指代,是建立在大众认可的角度上吗?
A&B中的there is one 中的one本来就有点指代不明（medical test or condition），接着再来一个when it is not按理it应该指代one，结果就更加无法有确定的指代。
its presence in D导致第二个when it is的it指代不明，究竟是condition还是its presence；E同理。

举四肢赞成，大家研究题目真的好细密！！！
this is a tough question.
继续请教关于referent和logical referent.
我认为，从语法上讲，choice A和B是有referent的，只是这个referent不合逻辑。类似例子有OG 43 choice B.
43. In the minds of many people living in
(B) before there was
OG在43题的解释说:
In B,
it has no logical referent, because the previous clause describes a time when there was no
同理我们可以认为83题的A/B也是没有logical referent. 可是83题的解释却是
In choices A and B, the phrase indicate that there is one does not grammatically fit with when it is not because it has no referent.
一般OG说没有referent, 是说没有语法上的指代对象; 说没有logical refernt，是说有语法上的指代对象，但是逻辑不对。

再贴一遍题目和解释，看得方便些。
83. Any medical test will sometimes fail to detect a condition when it is present and indicate that there is one when it is not.(A) a condition when it is present and indicate that there is one
(B) when a condition is present and indicate that there is one
(C) a condition when it is present and indicate that it is present
(D) when a condition is present and indicate its presence（C）
(E) the presence of a condition when it is there and indicate its presence
Only choice C, the best answer, produces a sentence in which every pronoun it refers clearly and logically to the noun condition. In choices A and B, the phrase indicate that there is one does not grammatically fit with when it is not because it has no referent. Choices B and D are imprecise in saying that a test will fail to detect when a condition is present, since the issue is the presence and not the timing of the condition. Further, its presence in D leaves the it in when it is not without a logical referent: it must refer to condition, not presence. Choice E repeats this error; also, the presence... when it is there is imprecise and redundant.
我觉得OG说法没有错.
先看43题B选项: before there was
最后反观83题的正确答案C: Any medical test will sometimes fail to detect a condition when it is present and indicate that it is present when it is not. 整个句子很清晰地说明, and前后所指代的内容完全相同, 就是前面提到的那个condition.
不知道我的理解是否有问题, 拿砖给个批判吧
其实will fail to detect a condition when...and indicate sth when... 我感觉更对称一些.
我想indicate its presence 不如indicate that it is present 是因为 最后的 when it is not 后承前省略了present, 用indicate that it is present when it is not 比较通.
我觉得这个解释比较好
will fail to detect a condition when...and indicate sth when... 我感觉更对称一些.
同意，从 and 前后的平行来考虑
长了不少知识,加深理解了啊~~~~
A&B中的there is one 中的one本来就有点指代不明（medical test or condition），接着再来一个when it is not按理it应该指代one，结果就更加无法有确定的指代。
its presence in D导致第二个when it is的it指代不明，究竟是condition还是its presence；E同理。
豁然开朗啊~~~NN！！！
