For them【C2】______growth means faster progress towards a critical situation. Ofgem, the energy regulator, has long【C3】______that the margin between peak electricity demand and【C4】______supply is falling. In June it said the margin would【C5】______from 14% in 2014 to just 4% in the winter of 2018, increasing the risk of blackouts【C6】______the weather turn cold or a power station or two【C7】______.
Since that report Britain’s economy has grown fast. Ofgem’s assessment【C8】______that Britain would grow by about 1.6% in 2017. The Bank of England now【C9】______2.8% growth. This will【C10】______consumption. Over the past decade an increase in peak electricity demand of 0.5%【C11】______each additional percentage point of economic growth.

【C12】
选项
A、sink
B、stick
C、ascend
D、expand
答案
A
解析
