— Have our travel plans been decided?
— No, still .
A. out of order
B. up in the air
C. in the case
D. in the way

A. out of order(答案→)B. up in the airC. in the caseD. in the way解析：句意：—我们的旅行计划决定了吗？A. out of order无序；B. up in the air悬而未决；C. in the case万一；D. in the way妨碍; 挡道。根据前面的no可知后一句意为：不，仍然悬而未决。由句意可知选B。考点: 考查短语的用法。

我明天再问问老师，叫他解释下这个问题
