OG62，划线部分是什么意思啊

62. Geologists believe that the warning signs for a major earthquake may include sudden fluctuations in local seismic activity, tilting and other deformations of the Earth's crust, changing the measured strain across a fault zone, and varying the electrical properties of underground rocks.

(A)  changing the measured strain across a fault zone and varying

(B)  changing measurements of the strain across a fault zone, and varying

(C)  changing the strain as measured across a fault zone, and variations of

(D) changes in the measured strain across a fault zone, and variations in

(E)  changes in measurements of the strain across a fault zone, and variations among

这个题目的划线部分到底是什么意思啊，changes in the measured strain a fault zone?

我的中文翻译很烂，就不说意思了，代为分析一下。

A, B, C中changing不对，应该用名词形式，而不是动名词。

D里in the measured strain, measured是形容词，修饰strain，所以核心词是strain. E改变了句意, 核心词是measurements. 另外，OG上也说了among和in的区别。

changes in the measured strain across a fault zone, and variations in

被测量的经过有故障区域的张力的改变和地下的岩石的电特性的变化。。。

我试着翻译一下吧：请指正

地质学家们认为，一场大地震的预警信号包括，当地地震活动的突然波动，地壳的倾斜与变形，地质断层间受测量张力的变化，地下岩石电属性的变化。

明白多了
