Logical predication; Parallelism The correct parallel structure in the original sentence emphasizes the contrast between where sunspots are found (are visible … Sun) and where they are not (have never been sighted … equator). Sunspots is the subject of the sentence; are is the verb of the fi rst part of the contrast, and have been sighted is the verb of the second. (Th e adjective visible is a complement and is parallel to the past participle sighted.) Both parts of the sentence conclude with phrases indicating location. The contrast itself is indicated by the conjunction but. A Correct. Th is sentence clearly and correctly draws a contrast between where sunspots are found and where they are not. B Th e modifying clause that never … Sun distorts the meaning of the sentence; also, without punctuation, the phrase on the surface of the Sun the Sun’s poles or equator is ungrammatical and makes no sense. C 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. D Although usually introduces a subordinate clause, but there is no subject of the clause and having been sighted is not a complete verb phrase. E The is phrasing makes the sentence somewhat awkward and unclear.
是这里吗，GMAC估计想说这里应该用被动。作者: 大宝店小二 时间: 2012-4-25 21:21
although 之后应该是加完整的句子吧！作者: wangjieava23 时间: 2012-5-3 19:53
楼上，although 是主从连词，一般用法是要接完整句子的。但是有些时候 although 引导的成分做插入语，是会要做一些变形的。
