分析 我们学校大约三分之二的老师生于20世纪七十年代.
解答 答案:B 联系汉语意思可知,此处所缺用法为分数,根据已有的知识储备可知,分数的表达方式为:分子为基数词,分母为序数词,分子大于一,分母加s.所以此处三分之二的表达方式为two-thirds.又知当分数作主语时,其后的谓语动词形式取决于后边的名词的单复数;teachers为复数,be born意为出生于…,且用于过去时,故此处用were.根据时间介词in可知,此处应用不具体的时间,可接年份,也可接年代,即in+the+年代s.综上所述可知此处应用the 1970s.故选B.
点评 此题考查分数的表达及用法.日常的积累是做题的关键.分数的基本结构为分子为基数词,分母为序数词,分子大于一,分母加s.且分数作主语时,其后的谓语动词形式取决于后边的名词的单复数.同时此题要积累排除法的做题方式.
