这题og给的解释确实牵强了点，我觉得C的错在sighted修饰对象的问题

请问这个修饰对象sunspot有什么问题呢？

有修饰dark spot的歧义

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

我觉得AC的区别应该是have never been sighted和never sighted 的区别。

A中，but连接两个平行结构的表达，即are visible as dark spots on the surface of the Sun 和have never been sighted on the Sun’s poles or equator. 而havenever been意思是“至今还没有太阳两极和赤道附近出现”，have been强调对现在的影响。

而C中的一般过去式则不能表达出“从过去到现在都没有出现的意思”而是表示“在过去某一时间点出现过”，没有了这一个持续性就是原题的逻辑意思错误了。

此外，这两道题在每个句子中起的作用不一样。我一般就是读意思，lz吧正确选项带入，仔细体会一下逻辑意思。

as dark spots 最好是就近修饰，否则会引起歧义。

c中不是一般过去式，过去分词
