OG SC 14题，不会做，求助！

eynl12345

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 onthe Sun’s poles or equater.
划掉的部分是插入语，所以主语是sunspots
(A) are visible as dark spots on the surface of the Sun but have never been sighted on==>这是svo but vo的结构，时态没有问题，but have never...的逻辑主语也没有问题，语法和句义都符合

(B) are visible as dark spots that never have been sighted on the surface of the Sun ==>这个选项的意思和A有很大的差别，要分清楚原句的意思是sunspots have never been sighted on the ....还是dark spots have never been sighted....，因为这个that就近修饰的是spots, 而这里的dark spots是用来作比较参考的东西，所以根据句义这个选项的修饰对象有问题

(C) appear on the surface of the Sun as dark spots although never sighted at ==> 这个选项的句义改的就更加离谱了，sunspots是作为dark spots appear on the surface of sun, although 后的逻辑主语是sunspots, never sighted at

(D) appear as dark spots on the surface of the Sun, although never having been sighted at ==> 和C 一样的问题，而这个问题更加严重，haveing been 了，哪有现在在进行吗。在G的规则中，进行时都是少用的，别说是现在完成进行时了。manhann bible里说了，这种自然规律通常都是用一般现在时的，不用进行时的

(E) appear as dark spots on the Sun's surface, which have never been sighted on==>which修饰有问题，后面的内容都是修饰surface的， 可以看得出来逻辑句义已经错误了

中文分析的很奇怪的，但是gmatclub有关于这道题的分析，他们说的很清楚
Option-C,D: are out since the sentence is not a cause-effect sentence i.e Reason for sunspots being visible on the surface of the sun, is not because they are never sighted on the Poles or equator.
Option B: modifies dark spots which changes the intended meaning
Option E: modifies surface and that makes no sense
Option A: Correct.

其实最近复习manhann 的SC bibile以来就觉得，所谓的逻辑句义不对，就是修饰错误

可是请问A里面的as N不也是作为的意思么？
而且C的逻辑主语是sunpots有什么问题呀。Although引导的状语可以省略相同的主语以及be动词，这难道不是although they are never sighted的省略形式么

azhongzhong

楼上说：Although引导的状语可以省略相同的主语以及be动词，不知道出处在哪里？OG的解释是说Although引导的句子必须完整，所以C错。请牛牛解释一下“Although引导的状语可以省略相同的主语以及be动词”是否可省略，谢谢！

对应E选型的解释，我不是很赞同啊。为什么就说which是修饰surface的呢？GMAT并没有说which的非限制性定语从句就是就进修饰~在OG12的第一题的解释中就可以看出，GMAT还是倾向于which修饰的是句子的主语，而非介词短语中的宾语。而且这题中Which后面的动词也是复数形式，更加说明了which修饰的不是surface。我觉得OG中的解释“somewhat awkward and unclear”应该是说这个非限制性定语从句离主语太远了，因此修饰在一定程度上来书是不够清晰的。另外，我觉得which多少把but的转折之意去掉了~因此E选项不能算是最佳选项

可是which不是可以跳跃修饰么。E中的which应该是修饰到了dark spots.因为dark spots 后面是介宾短语。而如果是就近修饰sun's surface可以看出单复数是不一致的。只不过因为这个dark sports 并不能完全等于主语sunspots所以有误。
这是我的看法。

净植

的确which不修饰介宾短语里的宾语，但是它会就近修饰介宾短语前的名词即是dark spots.因为sunspot不能完全等同于dark spots（因为它不是called 的关系而是appear as）所以这个which还是没有正确的修饰到主语sunspots.

OG中玻璃山的那个题正确选项是就近修饰James Cook的。的确 转折被省略了
最后 在指代优先权的影响下 主谓不符可以作为错误之一。
The Glass House Mountains in Queensland, Australia,
were sighted in 1770 by the English navigator Captain
James Cook, by whom they were named supposedly
because its sheer wet rocks glistened like glass.
(A) by whom they were named supposedly
because its
(B) by whom they were named supposedly and their
(C) naming them supposedly since their
(D) who so named them supposedly because their
(E) who so named it since supposedly their

我想问一个是..A为什么可以是have never been ....而不是和前面的“are visible”平行成"are never sighted.."呢..

我觉得这个c选项分析的不对  错不是在逻辑主语 而是在although的省略 og中的解释也是说sighted is not a competed verb, 也就是说不省略的话应该是although never have been sighted， 这才是complete verb although在引导从句时，被动的情况不可以省略 逻辑主语并没有错 只不过是省略错了

弱弱问一下，which不是也有 跳跃修饰 核心词的用法么？这里为什么是就近修饰？？

解释太牛！谢谢！
