Sound can travel through water for enormous distances, prevented from dissipating its acousticenergy as a result of boundaries in the ocean created by water layers of different temperatures anddensities. A. prevented from dissipating its acoustic energy as a result of
B. prevented from having its acoustic energy dissipated by
C. its acoustic energy prevented from dissipating by
D. its acoustic energy prevented from being dissipated as a result of
E. preventing its acoustic energy from dissipating by

这题选C，主要是想问问，都说这是独立主格结构，但是这样逗号前后不都是完整的句子了吗……有人说C的原语序应该是prevented its acoustic energy from dissipating by ……这玩意怎么看出来的……求指导

我懂了……后面那个不是完整句字……这里有个类似的题，大家参考一下吧……立马就懂……
DARPA’s Falcon Hypersonic Technology Vehicle can fly as fast as 6X the speed of sound and can
attack a target 2000 miles away in 30 minutes, its engine’s thrust prevented from dissipating in the
stratosphere by its conical unibody design.

A. its engine’s thrust prevented from dissipating in the stratosphere by its conical unibody
design
B. preventing its engine’s thrust from dissipating in the stratosphere because of its conical
unibody design
C. preventing the dissipation of its engine’s thrust in the stratosphere due to its conical
unibody design
D. prevented its engine’s thrust from being dissipated in the stratosphere by its conical
unibody design
E. its engine’s thrust is prevented from being dissipated in the stratosphere because of its
conical unibody design

第二个选A

我的想法希望能帮助到你^^
A选项
1、修饰主语问题enormous distances/sound is prevented from dissipating….?
2、若修饰主语是sound，意思也变了，原意能量防止被分散；A声音防止能量分散，声音不主动防止分散，被动变主动加入额外主语
3、pissipate是不及物动词，后不能直接加n
B选项
having done都应替换成be done，但是替换后是prevented from energy being dissipated，不简洁，应该是preveted energy from disspating——直接就是C选项的独立主格最简洁明确
E选项
sound主动preventing错，被动变主动

prevented 不是energy的谓语动词，是个过去分词形式的形容词
