q51v35.不好意思狗放晚了,昨天晚上快十点到学校,实在撑不住闷头大睡到中午献上记忆中残存的狗,想起新的会随时补充: AI:"The best teachers are those who expect their students to challenge popular ideas rather than accept them" AA:The following appeared in a memorandum from the Director of Human Resources to the executive officers of Company X. “Last year, we surveyed our employees on improvements needed at Company X by having them rank, in order of importance, the issues presented in a list of possible improvements.Improved communications between employees and management was consistently ranked as the issue of highest importance by the employees who responded to the survey. As you know, we have since instituted regular communications sessions conducted by high-level management, which the employees can attend on a voluntary basis. Therefore, it is likely that most employees at Company X now feel that the improvement most needed at the company has been made.”
Q: 1.DS题:有一堆物品A, 有两个属性,颜色(绿色或非绿色)和材质(羊毛或非羊毛),问绿色且非羊毛的占比例是多少?(1)非绿色且非羊毛的占2/5 (2)非绿色且羊毛的占1/2 我选E 2.DS题:K 是正整数,x是负数,问k^x是否小于1 (1)k不等于1 (2)x小于-3 我选 A 3.PS题:x1≤X2≤X3≤X4≤X5, X1+X2+…X5=250 这五个数的中位数是40,问X5最小值。选65 4.PS题一个正方体,用三种颜色涂,每个面涂一种颜色,相邻的面不能涂同一种颜色,问一共几种涂法。我没算当时,按狗的答案选了6 5.还有一个就是N个连续正整数相加得52那道,选N=8
V 洛基:网购的好处是有不同的品牌可以任购买者挑选,但对于日用品来说,品牌间差异不大,人们也不会挑选特殊的品牌,并且人们清楚自己可以在什么地点买到什么商品。因此,在日用品方面,网购的好处不如传统购买方式。问论证忽略了什么问题。选了忽略了网购日用品可能还有其他好处,不仅仅是有多种品牌可供选择。
阅读: 1.lava的那篇,狗已经很全了,文章也不难读懂。只记得问了是什么可以证明这种exchange的存在,选了熔岩的成分。
2.非狗,production-smoothing models(生产平滑模型) ,一屏 第一段:定义“生产平滑模型”,解释了如何利用库存来平滑由于需求的变化而带来的生产数量的波动。并且说利用库存平滑生产可以降低成本(由于调整生产要比增加/减少库存贵)。 第二段:有利用aggregation data(好像是这两个词)的研究表明,生产平滑模型是无效的。这里有题,问作者提到aggregation data为了说明什么。 第三段:总体来讲还是在批驳这个模型,说来自公司的数据没有证明这个模型有想象中那么有效。
3.狗狗里鸟类声音系统的进化 记得有好几道题考察“不同种类的鸟的声音系统是分开进化的,而不是来源于同一个祖先。”以及“无论对于鸟还是对于人,大脑有同一个区域专门负责声音的控制之类的”
只能回忆起这么多了,先写到这里~~祝正在奋斗的G友们都能取得好成绩! |
