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.

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

比较困惑的是D项为什么错？

答案是A。

yadore

although后面跟完整的句子，而D选项although后的句子没有主语

uniquenellie

although后面必须跟完整的句子？？不可以把主语省略直接用动词的分词形式吗？

jbc88

不一定，有although省略主语的~ 不过是alithough在句首。。

恩。。这是个值得纠结的好问题。。顶个~

yadore

个人感觉，although省略的情况是：若主从句主语相同，且从句谓语含有动词be, 可将从句主语和动词 be 省略。
但这个例子，明显不是这个情况。所以要跟完整的句子吧~
而且没有主语，感觉语义不是很清楚。
欢迎讨论

您说的这种情况，能举个例子吗？although后面省略主语和be动词的例子

我觉得本题C选项although就是个省略的用法，不过被省略的主语具体指代有歧义，是指sunspots还是dark spots?...不知道我这样理解的对不对。

appear as dark spots on the surface of the Sun,
although never having been sighted at

感觉不应该用having吧

楼上说对了！不能用having。although后面接完整的主谓结构，补出主语，很清晰不是主谓结构。另外，随意添加实义动词appear。

although后面跟省略，在本题中应为although never sighted最简洁，
或在牵强一些，也应该是although having never been，although never having been 错。
另，although 从句省略一般感觉although领的内容不是句子主要意思，而且多作为插入语或句首。象本题是句子主要意思，所以尽量不要省略。

一点浅见。
