求解关于独立主格的问题，PREP-155

With surface temperatures estimated at minus 230 degrees Fahrenheit, Jupiter's moon Europa has long been considered far too cold to support life, and with 60 square miles of water thought to be frozen from top to bottom.

A. Europa has long been considered far too cold to support life, and with

B. Europa has long been considered far too cold to support life, its

C. Europa has long been considered as far too cold to support life and has

D. Europa, long considered as far too cold to support life, and its

E. Europa, long considered to be far too cold to support life, and to have

答案是B，我在做的时候迷糊了，总感觉（Jupiter's moon Europa has long been considered far too cold to support life ）和 （its 60 square miles of water thought to be frozen from top to bottom）之间是不是应该加个and?? and its这样呢？

不是说逗号不能直接连接两个分局吗？
后来看了解释知道Its 后面是独立主格，但是这里是怎么判断独立主格和2个分局呢？ 如果加and对吗？

求NN，斑竹解答一下~

补充一下，我的意思是：B：Europa has long been considered far too cold to support life,  and its

加and的话前后形式不平行

逗号后面没有谓语动词，所以不能成为一个单独的分句。如果要加and 的话，应该变成
Europa has long been considered far too cold to support life,  and its square miles of water are thought to be frozen from top to bottom.

逗号加and是可以连接俩分句的，独立主格结构是没有谓语的，既然后面的句子是非划线部分已经决定了是没有谓语的句子，就前面不能用and啦

句尾的thought to be不是谓语的，只是一个分词形式，说明后面不一定是一个句子。

把握好句子的中心主干就不会将主要谓语动词和修饰结构中的谓语动词搞混淆。

这个句子的重心就是在说某星好冷，句首的with独立主格以及句尾的独立主格都是在说明到底怎么冷，也就是在修饰主句。其实，抛开结构不看，从意思上也可以感知到句首句尾成分是在说明怎么冷。
