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。
