The passage is chiefly about ______. [br] The deep-sea listening system makes use of ______.
选项
A、the sophisticated technology of focusing sounds under water
B、the capability of sound to travel at high speed
C、the unique property of layers of ocean water in transmitting sound
D、low-frequency sounds traveling across different layers of water
答案
C
解析
根据最后一段“…different layers of ocean water can act as channels fox sounds, focusing them in the same way a stethoscope does…”海洋中的不同水层可以作为声音的传播渠道,将声音聚集。这就是海洋中相对微弱的声音,甚至是低频的声音,也经常能传播几千英里的原因。水下监听系统正是利用不同水层能将声音汇集起来使其传播得很远这一特性而设计的,故C正确。
