Changes in sea level are not only a result of changes in water temperature, affecting water density, but of melting glaciers as well.

(A) are not only a result of changes in water temperature, affecting water density, but of melting glaciers as well
(B) not only result from changes in water temperature, which affect water density, but also when glaciers melt
(C) are a result not only of changes in water temperature, which affect water density, but also the melting glaciers
(D) result not only from changes in water temperature, which affect water density, but also from the melting of glaciers
(E) result from not only changes in water temperature, affecting water density, but as well as when glaciers melt


答案D，想问D中的which指代什么？changes？
A与E中的affecting，是修饰前面的temperature还是前面整个句子（如果前面主句不是系动词）因为语法笔记上说：伴随状语只能修饰主句的动词性谓语，不能修饰主句系动词。而A选项错误的解释是……分词结构affecting在该句中是做后置定语修饰紧邻的名词temperature。 但是我认为通常这种情况下，affecting前面有逗号都是修饰前面整个句子的吧。

which这里是代temperature

Ving现在分词状语：做定语/状语
主谓宾结构，表伴随/结果，做状语
主系表结构，修饰名词成分，做定语
Ved是就近修饰的

另外楼主把划线部分编辑一下吧：）

如果which指的是temperature，affect不是应该用affects么？还是说temperature用复数？

which 的确有指代 temperature的倾向，但就像你说的，从单复数可以知道，这里的which指代的是 changes
