CD选项中although是否一定加完整句？官方解释说少了主语且没有动词，那也就是说although要加完整句，但verbal分册中36题正确答案Although eradicated in the US, polop continues ……中although后面加的不是完整句，所以不清楚什么时候加完整句什么时候不加完整句。

另外，E选项which是否有修饰歧义？which应该是可以跳跃修饰的，在A 介词 B，which中which是修饰A的，应该不会有歧义，但是OG解释说awkard and unclear

although 后面是要跟完整句子的。正如og解释中所说
og verbal 那题，although 后面省略了 主语(polop)。因为，主句 polop continues....
当 although 引导的从句 主语 和 主句主语 一致时 although 引导的从句主语 可以省略

14.    A. but signifies the contrast structure, two items being compared must have similar structure, are and have been are not parallel but are and have are parallel. B. distortion of meaning. The author’s intent is that sunspots are found on the surface of the sun but not on the poles and equator. C. although must follow an subject and verb D. although problem. E. modifier intends to modify sun’s surface thus it is incorrect. the modifier must touch the noun which is being modified, in this case, the intended noun sunspot is too far away from the modifier, thus it is unclear.

这是我刷OG时候做的笔记，不知道可以不可以帮到

同意3L，altough确实一个连词需要跟一个完整的句子，只不过是altough后面句子里的从句主语和主语主语一致时可以省略。

E选项的which有歧义，按照lz的理解，which修饰了dark spots，但是按照句子的原意which应该修饰的是sunspot而不是dark spots，sunspot只是dark spot的一种。而且，原句在本质上只是想表达两个并列的描述，sunpots are but have是一个平行。

另外，which在这里的跳跃修饰也有待商榷，我个人的意见，A 介词 B，which 这个结构，要想跳跃修饰，介词B必须distinguish了A这个antecedent，这个介词短语一般都是of短语来说明A的属性，E选项中的on the sun's surface没有说明sunspot的属性，因为我们都知道sunspots就在太阳表面，有没有这个介词短语并不重要，所以理解成跳跃修饰不准确。

个人意见哈~~看看NN们怎么说~
