单选题 The French pianist who had been praised very highly ______ to be a great disappointment.
  • A. turned off
  • B. turned up
  • C. turned out
  • D. turned down


【正确答案】 C
【答案解析】[分析] turn out“结果是”，“证明是”；turn off“关闭”；turn up“证明是”，等于turn out to be，但其本身不与to be连用，因此，不能入选；turn down“(能被)翻下(向下折转)”，“调低(音量等)”。只有C符合句意和语法要求。
