问题 All staff members are reminded that you should not use the executive restroom______ you have written authorization to do so.
选项 A、for
B、unless
C、without
D、although
答案 B
解析 横线前后都是完整结构，故横线处应填入连词。先排除介词(C)without，将其他备选答案一一代入后分析全句。 you have writtenauthorization to do so(有书面批准)是use theexecutive restroom(使用主管休息室)的条件，故答案是(B)unless。
