30下午数学少量jj

huzhiqi

因为就数学得分还行，所以提供一些资料参考。

1、给了如上的图形，问有多少个矩形。

2、(x^2-1)/(x-1)=x，求x有多少个解。 答案选项 1，2，3，3各以上，none

3、还有一道题很纠结，可能数学的扣分点就在这题上。这道题目因为没看太懂，所以记忆有些模糊，如果谁碰到了类似的题目补充一下，看数值是否有什么错误。

年	人数	每个人拥有
1884	17，000	10
1980	123，000	41

大概说是有地区人从1884到1980所占土地面积，求增长率   答案选项中有31%，106%，21%等等

4、求下面哪个值最小  2^(-5),2^(-6),2^(-7),2^(-9)*7 我记得是选2^(-7)

5、俩台机器做工，第一台机器生产一吨物品所需时间是第二台机器单独生产的3/4，两台机器速率固定，且两台机器合作生产一吨物品需要6小时，问第二台机器单独生产一吨物品需要多少小时

6、x^2/|x|=? 答案是|x|

7、从20人中选5人和从种选4人得比例 16/5

现就记得这么多了，要是想起来再补充，个人觉得数学是开头题目陷阱都比较多，特别是数据充分题目，A,B两个选项很多都要仔细看看实际算一下，不能凭感觉估计就做出选择。

verbal部分太痛苦，4片阅读除了浮游生物那篇，其他3篇是目前jj上都没有出现过的，一片火星探测的有关冰层和极点的，还有一个是讲二战和内战期间农业种植，农民罢工什么的，反正都是满屏多的文章。看得直晕~~

语法平行结构考得很多

while, with,which,so,as,and都有考点

作文

issue: 人们只愿意接受这样的领导：他能完成他要求其他人完成的任务。

argument:

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.” Discuss how well reasoned . . .etc.
