SC为神马感觉OG自相矛盾了？求解！！

OG 13,第17：Sunspots, vortices of gas associated with strong electromagnetic activity, are visible as dark spots on the surface of the Sun but have never been sighted on the Sun's poles or equator.
A) are visible as dark spots on the surface of the Sun but have never been sighted on
B) are visible as dark spots that never have been sighted on the surface of the Sun
C) appear on the surface of the Sun as dark spots although never sighted at
D) appear as dark spots on the surface of the Sun, although never having been sighted at
E) appear as dark spots on the Sun's surface, which have never been sighted on


我选C，正确答案A，解释是Although typically introduces a subordinate clause, which has a subject and a verb, but here there is no subject and sighted is not a complete verb.


OG Verbal 2,第36：
Polio, although it is eradicated in the United States, it continues elsewhere and is able to be brought into the country by visitors.
A) Polio, although it is eradicated in the United States, it continues elsewhere and is able to be
B) Polio, although eradicated in the United States, it still continues elsewhere and can be
C) Although still continuing elsewhere, polio has been eradicated in the United States and could be
D) Although having been eradicated in the United States, polio still continues elsewhere and is capable of being
E) Although eradicated in the United States, polio continues elsewhere and could be
吸取教训选了看起来怪怪的A，结果答案是E。。。


求大神分析一下上题C选项和下题E选项有毛线区别。。。跪谢！

亲，although后面可以接adj成分的，前提是时态必须和主句一致。
这两天的句式都没有问题，第一题错在时态上，完成时的意味丢掉了哈。

我记得当初自己也在这纠结了N久，结果发帖问到最后也没有弄的特别清楚。不过现在回头看看已经差不多理解了OG的意思。首先，不知道LZ知不知道状语从句省略这回事。如果不知道可以看prep2008，上面说的很清楚，简单的说就是表达转折/时间/让步的连词，在从句的主语还是主句主语，且从句的动词时be动词的时候可以一起省略主语和be动词，变成连词+ving/ved/adj的形式
然后再看这两道题。首先看第二道，这道题和OG上一道题其实是一样的，Though called a sea, the landlocked Caspian is
actually the largest lake on Earth, covering....
简化这两个结构就是：Although/Though ved/ving/adj,SVO或者S,although/though ved/ving/adj, VO.
这里为什么可以省略呢，是因为修饰S的时候不可能有歧义，它不可能修饰O或者其它的noun。
但是看第一道题，这道题C的结构是SVO+although/though ved/ving/adj，这里修饰是很容易引起歧义的，因为它离O更近，所以这也是为什么OG上认为当although,though放在后面引出从句时必须有自己的主语和动词的原因~

第一个正确答案是A嘛？？我看到1000SC大全的答案怎么是C呢。。。Curiouser and curiouser...

简单的说一下，尽管用了Although但36题Although eradicated in the United States，仍然只是状语，并不是完整的从句。它的形式与Ving或ved作状语的形式一样。并与主句间用逗号隔开。

但17的C选项，主句后没有逗号作隔离，直接用连词Although，所以在形式上必须要跟一个完整的从句，否则缺少be 动词形式的sighted 完全可以被认为是在修饰dark spots ，这与句子意思不符。

这里我强调一下，17 题的although使得句子的逻辑关系有些混乱，我个人认为这是C和D最先被排除的关键。
