Because Miranda, the smallest moon of Urants,has a large number of different surface features, including craters,mountains,valleys,and fractures,some astronomers suggest that at one time,the surfacce broke apart as a result of repeated impacts, after which the fragments rejoined through mutual gravitational attraction.
这是正确答案，但是which 在里面是什么成分呢？解释上说是第二层的定语从句，那which指代的是什么呢？不是说逗号后面which不能指代前面的整个句子么...？
我语法一直不太好...请教...
贴全哦
答案是比较出来的 如果原题每个选项都是which放这儿的就不用理了~
理论上非限制性定语从句which不能指代前面整个句子
一般用现在分词状语修饰，as好像也可以指代前面整个句子的（比较少见）
