hour, hour’s, hours’, conserved, preserved, reserved With no result after one ______ discussion, we ______ the question for the next meeting.
【正确答案】:hour's, reserved
【题目解析】:第一空考查的是属格的用法,“一个小时的讨论”用 one hour’s discussion。Conserve指“保存”,preserve表示“保护,保存”,reserve指“保留,延期”,此句意思是我们把这个问题保留到下次会议再讨论,因此用reserve。
