Sunspots, vortices of gas associated with strong electromagneticactivity, are visible as dark spots on the surface of the Sun but have neverbeen sighted on the Sun’s poles or equator.
(A) are visible as darkspots on the surface of the Sun but have never been sighted on
(B) are visible as darkspots that never have been sighted on the surface of the Sun
(C) appear on thesurface of the Sun as dark spots although never sighted at
(D) appear as dark spotson the surface of the Sun, although never having been sighted at
(E) appear as dark spots onthe Sun’s surface, which have never been sighted on

C解释说Although typicallyintroduces a subordinate clause, which has a subject and a verb, but here thereis no subject and sighted is not a complete verb.
但是08笔记说(1) 表示时间/条件/转折/让步的连词(when/while/if/unless/although/eventhough/even if) + 形容词短语/-ing短语/-ed短语
(逻辑主语等于句子主语) (所以when a child/ whenchildren是错的； if + n.也是错的)
那这个C不就符合了吗，although+ sighted,逻辑主语是sunspots, sighted表示被动，被sighted呀
