数学印象特别深的： 第二道题：条件是做公交上班的人里男性职员占30%，女性职员占20%，整个公司的职员分布是twice as many men as women，这儿我就晕了到底是男的是女的的两倍还是女的是男的的两倍= =丢人啊，最后蒙了个女的是男的的两倍，得出来是7/30，不过提交之后越来越觉得貌似错了应该是4/15...
还有道航空公司用电话的，题干是飞机上的公用电话收费很贵，但用的人很少，特别是现在有了手机。但是航空公司可以从收费中获得收入，而且不用付钱给维护电话的公司。所以航空公司可以从电话上获利。问这个结论depend on which assumption。1.安装电话的公司可以从中获利。2.虽然人们不爱打电话，但是人们希望飞机上有电话 3.只有不用手机的人才用电话 4.电话没有重到需要改变飞机的建设材料才能承受的地步。 我选了4，因为获得收入和获利是两码事，还要考虑成本，虽然这个选项乍一看很不靠谱
作文AA是The following appeared as part of a bu siness plan created by the management of the Take Heart Fitness Center. “After opening the new swimming pool early last summer, Take Heart saw a 12 percent increase in the use of the center by members. Therefore, in order to increase the number of our members and thus our revenues, which depend on membership fees, we should continue to add new recreational facilities in subsequent years: for example, a multipurpose game room, a tennis court, and a miniature golf course. Being the only center in the area offering this range of activities would give us a competitive advantage in the health and recreation market.
