问题
What proportion of the world’s electricity supply is provided by hydroelectric power? [br] How far water drops to the turbines in a power station is known as ______ .
选项
A、the heads
B、the flow rate
C、the vertical distance
D、the heights
答案
A
解析
本题考查水落到涡轮的垂直距离的学名,故将答案出处定位到第五段。该段介绍了决定发电站的发电量的两个因素:the“head”和the flow rate。其中对the“head”作了解释:the vertical distance that the water falls, called the“head”,指出水落下的垂直距离称为“水头”,其中题干中的How far water drops to the turbines是对the vertical distance that the water falls的同义转述,故[A]为答案。
