小弟用的是iPad版本的小站TPO，而这题答案和详解都令我疑惑，想看看大家的意见 http://i.imgur.com/uYCCJIy.jpg While the warm-water countercurrent usually lasts for two months or less, ther e are occasions when the disruption to the normal flow lasts for many months. In these situations, water temperatures are raised not just along the coast, b ut for thousands of kilometers offshore. Over the last few decades, the term E l Nifio has come to be used to describe these exceptionally strong episodes an d not the annual event. During the past 60 years, at least ten El Nifios have been observed Not only do El Niftos affect the temperature of the equatorial P acific, but the strongest of them impact global weather. 5. Paragraph 3 supports which of the following statements about El Ninos, as t hat term is now used? A. El Nifios can originate in areas other than the Pacific Ocean. B. El Nifios can arise when warm currents last for two months or less. C. El Nifios affect water temperatures long distances from the South American coast. D. Multiple El Niflos can arise within a single calendar year. 我选的是C，根据第二句： In these situations, water temperatures are raised not just along the coast, b ut for thousands of kilometers offshore. 其实有点疑虑，因为题目问的是 as that term is now used，原文说现在是形容这种期 间，不是形容这种年际现象，而我根据的句子在这句话之前。但我以为改变的只是时间范 围，现象应该还是一样的？ 小站的详解我也不懂，在我看来 thousands of kilometers offshore 和 long distance s from the South American coast还满相符的。 再来说说详解的A，原文说 the strongest of them impact global weather，应该是El Nino影响全球天气，但选项是其他地方产生El Nino，这因果应该颠倒了；而详解说这也 意味这个现象可以起源於其他地方，A->B意味着B->A？ 最後又令我对详解抱持疑惑的是D的详解，是少打一个“未“吧… --
