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

ANS:A

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
白勇語法上寫到Although 若省略主語後面接 –ing , -ed , 形容詞短語
為何OG解釋although一定要有主語或是動詞呢

Zeldaw

although后一般来说要有一个完整的句子，所以OG说要有主语，谓语动词，宾语。当然也可以进行省略，省略的条件是，第一：主句和从句的主语必须是同一个主语。第二：将主语和Be动词同时省略。即although后直接接-ing ,-ed，adj等

那D選項
although never having been sighted 不可接受嗎？

按2楼的说法，D不是正确的么？

Sun sports are ..., although (sun sports are) never sighted ...

或者另一个解释，逻辑上这个从句应该用一般完成时。由于主句不是完成时，所以BE动词于从句不同，所以从句中的动词不能省？

就D选项说 首先句子本身就是单纯的转折 用although不用but意思上就很僵硬

而且having been这结构肯定是错的

前面...on the suface of sun后边跟..sight at the sun's..也不如sight on好吧

谁来谈谈although引导状从省略的问题吧...
