Since the start of the space age, more andmore littering has occurred in orbits near Earth, often because theintentional discarding of lens caps, packing material, fuel tanks, and payloadcovers.

A more andmore littering has occurred in orbits near Earth, often because

B orbitsnear Earth have become more and more littered, often from

C orbitsnear Earth became littered more and more, often resulting from

D therehave been more and more littering of orbits near Earth, often because of

E there had beenlittering more and more of orbits near Earth, often with
正确选项是B，当时我纠结的点在后面，可以排除掉because 和because of 的那几个句子，但是对from 和resulting from存疑，拿B选项来说，often from前面有逗号和主句隔开，那么这个from不是就修饰的是主句的主语吗，这样带进去貌似不合逻辑丫，orbits怎么能from the international discarding......呢？但是这句话里littered做的又是形容词，怎么可能是from的主语呢？难道from是修饰前面整句话吗？这个怎么看出来呀，求大神解释~谢谢~

A more and more littering has occurred in orbits near Earth, often because
》》》because + 句子
B orbits near Earth have become more and more littered, often from
》》》正确，from可以译作“因为”
C orbits near Earth became littered more and more, often resulting from
》》》时态错误，应该与since配合使用现在完成时态；resulting from构成的现在分词独立结构的逻辑主语是orbits，“orbits导致。。。”，句意不对。
D there have been more and more littering of orbits near Earth, often because of
》》》littering of orbits，句意不对
E there had been littering more and more of orbits near Earth, often with
》》》littering more and more of。。。nonsense；with引导的介词独立结构只能作定语修饰earth，nonsense。

那你能解释为什么often from不是修饰主语吗？

from引导的介词独立结构，这里from译作“因为”是做状语，所以修饰的是主句，而不是主语。
这里不是现在/过去分词独立结构，所以不涉及主句主语做逻辑主语这么一说。

恩恩，谢谢啦，后来我查了一下词典，from真的有这么一说，谢谢~
