又一道争议中的真题。。。

这题我选E，答案争议中。。。 有选C的。我觉得acoustic energy应该是被prevented,不合适主动prevent itself from dissipating. 你们怎么看？

37. Sound can travel through water for enormous distances, prevented from dissipating its acoustic energy as a result of boundaries in the ocean created by water layers of different temperatures and densities.

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

我选E。 因为preventing 的逻辑主语是sound.

是 sound 可以穿过水和遥远的距离，它（sound)可以阻止它自己的声动能（在穿越水流时）被基于不同温度和密度的水层造成的边界消散掉（dissipating）

似乎有理，咀嚼中...
