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】______.

选项
A、turn down
B、turn up
C、break off
