问题
What proportion of the world’s electricity supply is provided by hydroelectric power? [br] When do high head power plants use surplus electricity to transfer water to a second reservoir?
选项
A、In the morning.
B、At noon.
C、In the afternoon.
D、At night.
答案
D
解析
本题考查高水头电站在何时将多余的发电量转换到第二个储备库中,故将答案出处定位到第六段。该段介绍了水力发电分为两种.并分两段对其进行具体介绍,此段介绍的是high head power plants的发电过程,倒数第二句提到:在电力系统过剩时,而这个过剩的时间通常是在晚上(At times of excess electrical system capacity, usually available at night),其中surplus≈excess,由此可知,时间应是晚上,故[D]为答案。
