标题: GWD13 Q30 [打印本页] 作者: ssxxtt27 时间: 2011-8-9 18:33 标题: GWD13 Q30 For the first time in the modern era,non-Hispanic Whites are officially a minority in California,amounting to a little less than half the population of the state,down from what it was a decade ago by early three-quaters 这是个错误选项 解释说it无指代对象且用人数和年代对比错误。我的问题是：it指代population不行吗？a decade ago是状语，这样恰好是人数和人数比，哪里不妥？作者: soha111 时间: 2011-10-5 16:36
