问题     For most people Britain’s bouncing economy, now growing at its fastest for three years, is cause for cheer. Not,【C1】________for those who manage the country’s electricity power system. 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. John Feddersen of Aurora Energy Research thinks the capacity margin will therefore【C12】________to 2.6% by 2018 unless action is taken. That【C13】________into a one-in-seven chance of shortages, up from the one-in-twelve chance【C14】________was thought most likely last summer.
    Falling coal prices have kept Britain’s coal-fired power stations running at full【C15】________. That means many will have to close sooner than was【C16】________because European environ-mental laws【C17】________the total number of operating hours left to them. At the same time cheap coal has made electricity from gas un-competitive,【C18】________operators to put some gas-fired plants into long-term【C19】________. Renew-able capacity cannot yet make up the【C20】________.  
【C7】
选项 A、turn down
B、turn up
C、break off
D、break down
答案D
解析 空格的or连接两个并列的假设条件，前一种假设条件是天气转冷，从而加大供电负荷，导致停电的风险增大，由此可推断另一种假设条件应该是同样会导致停电风险增大的电站问题，故选D项break down“出故障”。A项turn down“调低”和C项break off“突然中止说话”代入，句意不通顺。B项turnup“出现”，若多出现两个电站，则更加不容易导致停电，与文意不符。
