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.
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C。 想问大家一下: 这句话到底是个什么结构的呀? its acousitc energy....是补充说明Sound吗? 请大家指教一下,我不太明白这个结构。
