37. GWD26-Q37

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

答案呢是C。C和D的区别在（1）dissipate是主动还是被动  （2） by 和 as a result of
我的疑惑是dissipate的语态，dissipate是个及物动词，its acoustic energy应该是被消耗啊，而该题的原句是Sound can travel through water for enormous distances, prevented from dissipating its acoustic energy by boundaries in the ocean created by water layers of differing temperatures and densities.从原句中也可以看出dissipate用被动语态更加好。等小伙伴们解答~谢啦

energy dissipating 是个常规用法，解释为能量损耗。dissipating也通常是被视作动名词用于表达损耗。而being dissipated 这样的表达可以用于作定语在名词后面，但无法单独表达这种动名词术语，而且显得很笨拙。
