7.A certain retailer promotes merchandise by using the following policy:
At all times there is either a “manager’s sale” or a “holiday sale” or both going on. All sales are run for exactly one calendar month. In any given month, if a manager wishes to clear out particular line of merchandise, then a managers’ sale is declared. If a holiday falls within the calendar month and there is excess merchandise in the warehouse, then a holiday sale is declared.
However, there is no holiday that falls within the month of August and, in that month, the warehouse never contains excess merchandise.
Which one of the following can be concluded from the passage?
(A) If a holiday falls within a given month and there is no extra merchandise in the warehouse that month, then a holiday sale is declared.
(B) If a holiday sale is not being run, then it is the month of August.
(C) If a manger’s sale is being run in some month, then there is no excess merchandise in the warehouse in that month.
(D) If there is not a manger’s sale being run some month, then there is holiday sale being run in that month.
(E) If there is no excess merchandise in the warehouse, then it is the month of August.
    答案是D，我觉得自己看题干有点似懂非懂，特别是红色的句子不是很明白。
     而且，按照我对题干的意思的理解，似乎没有答案，可能我理解的还不对。
     请高手指教，谢谢了

All sales are run for exactly one calendar month.的意思"每次sale"都持续1个月,就是说以月为单位把每次SALE都隔开了.
提干是说那个老板咧,每个月都有大贱卖,贱卖的借口有三种
1.为了HOLIDAY
2.为了MANAGER'S
3.为了both HOLIDAY & MANAGER'S
所以就(D) If there is not a manger’s sale being run some month, then there is holiday sale being run in that month.
        既然每个月都有贱卖,所以如果不是MANAGER'S 当然就是HOLIDAY了

(具体题目我也没读懂,我不知道什么是manager's sale...)

这偶明白点: At all times there is either a “manager’s sale” or a “holiday sale” or both going on. 任何时间都有促销, 要么是经理推荐促销, 要么是节日促销 (超市不是一直在促销么, 大家都知道啊, 就是说他们找着名头搞活动...) All sales are run for exactly one calendar month. 所有的促销活动都是为时一个月: 从1号到月的最后一天 (calendar month 就是整月,根据日历的划分)
