问题 The use of water referred in this passage is ______.
The oscillating water column produces power from ______.

选项 A、the turbine that powers the generator
B、the generator that produces electricity
C、the cylinders that drives the turbine
D、the air that escapes from the turbine

答案D

解析 这一题的重点在于分辨运用这种方法时,能源的来源在哪里。从文章的最后一段最后一句可以看出,海浪挤压气体,这种气体通过气缸,带动涡轮,从而带动发电机,产生能源。因此,这里能源的来源应该是气体,所以D选项是正确答案。
