英语句子结构分析？

among global warming's most frightening threats is the prediction is that the polar ice-caps will melt ,raising sea level so much that coastal cities from Newyork to shanghai will be flooded.请帮忙分析一下句子成分谢谢

Answer 1

这句话在the prediction 后面多写了一个is，正确的写法是
among global warming's most frightening threats is the prediction that the polar ice-caps will melt ,raising sea level so much that coastal cities from Newyork to shanghai will be flooded.
这是个倒装句。结构分析如下：
主语：the prediction that the polar ice-caps will melt ,raising sea level so much that coastal cities from Newyork to shanghai will be flooded
谓语：is (这是个系动词）
表语：among global warming's most frightening threats
在主语中，that 是同位语从句，用以解释prediction。
在这个同位语从句中，raising sea level so much that coastal cities from Newyork to shanghai will be flooded是现在分词短语作结果状语。

翻译：
预计两极的冰帽将会融化，从而导致海平面大幅上升，最终纽约、上海等沿海城市都将被海水吞没。这是全球气候变暖最可怕的威胁。

Answer 2

你应该多打了一个is,第二个is 是多余的。
among global warming's most frightening threats 是主语，is the prediction 是系表结构作谓语，that the polar ice-caps will melt是作prediction的同位语从句，raising sea level so much that coastal cities from Newyork to shanghai will be flooded是分词短语表结果状语。
句子大意为：在全球变暖的最令人害怕的威胁中就是那个预言：极地冰山将会融化，这会引起海平面的大量上升，以致于从纽约到上海等沿海城市将会被海水淹没。
