1209下午~狗狗和一点小感想

作文狗：AA:The following appeared in a memorandum from the CEO of a consumer electronics manufacturing firm to the head of the company's human resources department, who is responsible for hiring new employees:
   “Eight years ago, our firm’s profits were increasing with each new employee we added. We discovered that each employee had the skills and motivation to generate more revenue for the firm than his or her salary cost us. However, for the past two years, our profit margin has been falling, even though we have continued to add employees. Thus, our newer employees are not generating enough revenue to justify their salaries. We must not be hiring new employees with the same level of skills and motivation as those we used to attract. Clearly, then, failures in the human resources department account for our falling profits.”
AI:Everywhere,it seems,there are clear and positive signs that people are becoming more respectful of one another's differences.（希望对统计出现频率有帮助哦）
Q（50）狗：
1. t,s,q,v,  t/s＜q/v， 问一下是否落在t/s---q/v的区间里
（t+q）/(s+v)tq/sv(q/v)-(t/s)（把两个已知分数的分母分子分别相加，得到的新分数一定介于两个已知分数之间，记住这个就可以）
2.DS:k是正整数，问117k的最大质数公约数是什么
条件1：k是一位数的质数； 条件2：k是奇数
3.DS：在xy坐标轴中，直线l ,问它的斜率是不是为负
条件1：直线l的y截距是x截距的两倍
条件2：直线的y截距和x截距乘积为正
4.ACFG为正方形，ABC和CDF为等边三角形，求AEB的度数。答案是60度。（当时看完图直接60度了，嘿嘿，太感谢整理数学狗狗的同学啦）
5.求面积的图形题，直接用勾股定理或者30，60度特殊角很容易算的哈
6.还遇到几个化简题，我很无语。。。easy细心就好
7. DS127个员工的median如何确定？
1、有至少64人的工资大于或等于185000
2、有至少64的工资少于185000
8.DS：说n是一个数的平方，n被10除后余数是r,问r的值是多是？
条件1：n=625a;条件2：n=5^a
9.大于1000的四位数，千位和个位是偶数，十位和百位是奇数，问有这样的数有多少？答案是500.（不能太兴奋，一定得看清楚题目，不然真是心痛死了）
10.还有一道是狗狗里老师做家访写报告的题目，很容易算，仔细看题目
哎，verbal很悲剧，详细内容就不写出来了怕误导大家，貌似遇到了三篇狗狗，但是考场上记得很模糊（一个是关于benchmarking 三个标准的介绍那篇，还有一个是讲TIO2作为催化剂去除环境污染什么的，另外一个是14、15世纪妇女问题的争论）大家好好看看，NN们总结的很有道理，悔恨呐。。。
俺应该不想再考了，学校要求的比较低，不过真的很感谢CD的tx们，大家rp都太好了，真羡慕啊，祝筒子们好运吧O(∩_∩)O~
