Sunspots, vortices ofgas associated with strong electromagnetic activity, are visible as darkspots on the surface of the Sun but have never been 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 asdark spots that never have been sighted on thesurface of the Sun (C) appear on thesurface of the Sun as dark spots although neversighted at (D) appearas dark spots on the surface of the Sun, although never having been sighted at (E) appear as darkspots on the Sun’s surface, which have never been sighted on
选A, 但是我觉得吧,A中 on the surface of the sun放在dark spots后面有作定语的嫌疑修饰 dark spots 啊,而整句句子中,我觉得是做状语的。从后半句的on the sun's poles and equator看得出来。
那A选项是不是就产生歧义了呢!!?
