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.

【C9】

选项 A、witnesses
B、expects
C、enjoys
D、composes

答案B

解析 此段首句提到英国经济发展迅速,空格上一句用到过去式提及Ofgem曾对英国经济发展速度的预测(grow by…1. 6%),空格所在句用到now…2.8% growth,可推断这里是英格兰银行现在的预测,所以选B项expects“期望,预料”。A项witnesses“见证”和C项enjoys“享有”代入空格,均表示“现有的经济增长率”,但此处是承接上一句的“预计2017年增长率约为1.6%”,故此处的2.8%也应为2017年的增长率,而非现有增长率,因此排除这两项。D项composes“构成;写作;谱曲”后通常不跟“增长率”。
