语法与词汇 21.The scheme for rebuilding the city center______, owing to the refusal of a council to sanction the expenditure of the money it would have required.
【正确答案】 D
【答案解析】本句意为“重建城市中心计划,由于市政会拒批它所需的资金而失败了”。fell flat意为“(完全)失败,达不到预期效果”。如:The jokes fell flat.(玩笑毫无效果。)“fall down跌倒,在……方面失败;fall off跌落;fall out起纠纷,争吵”都不符合句意,因此正确答案只有D项。
