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

考点: 句子结构（Grammatical Construction） 主谓一致（Agreement）



1) 两个句子并列,第一个句子含有be动词,第二个句子中的be动词必须省略,同时,一些重复的名词或形容词也必须省略, 但是be功能不同时不能省略.



2) 单数复数: the percent of +可数名词复数形式, 谓语动词用复数
               



3) there be + n 句型中, be动词的单复形式由n的单复形式决定
               



4) 伴随状语不能修饰主句系动词

这里：“伴随状语不能修饰主句系动词”是什么意思啊？有例子吗？

顶一下，我也想问捏，是不是前面如果是一个主系表的句子，后面就没法用伴随状语？
