单选题 In order to catch up with continuous technology development, ______ managers agreed to introduce more intensive training programs.
  • A. every
  • B. neither

【正确答案】 D
【答案解析】[解析] 词汇：限定词 1．A选项every后面应接单数名词，B选项neither修饰单数名词。 2．C选项none作代词时后面无法接名词，要以“none of+the名词”的形式出现。 3．只有D选项both能与复数名词(managers)搭配使用。因此D为正确选项。
