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 E the best 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. 以上是在我下的GWD分类上的说法,可是看这句提供的原句不是应该A对一点?为什么说是E呢?
