我做的时候选的也是C,后来看了答案,觉得C从语法上没有问题,而是逻辑结构的错误。我的理解是: 后半句(即补充句)“60 square miles of water thought to be frozen from top to bottom”不能和前半句(即主句)“Jupiter's moon Europa has long been considered far too cold to support life”并列。前半句是对Europa的总体概括描述“太冷了不能维持生命”,那么后半句就是对这一描述的具象说明“60平方公里水域从上到下全部冻结”,那么在地位上它应该是从属于前半句的,所以不能和前半句并列。 正确选项B把后半句话作为次一等的从句处理从逻辑上讲是说得通的,至于是不是独立主格结构,我暂时是这么理解的,待查。
独立主格部分解释 详见楼上版主链接 Another kind of absolute phrase is found after a modified noun; it adds a focusing detail or point of focus to the idea of the main clause. This kind of absolute phrase can take the form of a prepositional phrase, an adjective phrase, or a noun phrase.
* The old firefighter stood over the smoking ruins, his senses alert to any sign of another flare-up. * His subordinates, their faces sweat-streaked and smudged with ash, leaned heavily against the firetruck. * They knew all too well how all their hard work could be undone — in an instant.
