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(force)across a fault zone, and variations in
(E) changes in measurements of the strain across a fault zone, and variations among
D, the best choice, describes the warning signs in parallel phrases. Despite surface appearances, the nouns changes and variations are parallel with tilting, but the verbal forms changing and varying in A, B, and C are not: tilting, one of the deformations of the Earth’s crust, is used here as a noun that is parallel to fluctuations, whereas changing and varying are used as verbs indicating some action undertaken. (平行) Moreover, these verbs are used incorrectly because the sentence mentions no subject that is performing these actions. (见到动词,要想到动词的发起人) B and E illogically state that it is not the strain but the measurements that portend danger, (平行不仅要注意形式上的平行,更要注意逻辑上的平行) and among in E wrongly suggests a comparison of different electrical properties rather than of different behaviors of the same properties. (??)
