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
