今天二战6XX, 比一战提高了近100分。但是觉得还是不够,上来放点狗,为三战攒人品。
真是的,GMAT我才不怕你,考三次就三次咯,我一定要打败你!!!!!

数学: M 50 机经很全了其实,这里只是补充一下.
新狗:1 有个圆圆心在X-Y坐标系原点,有点P在圆上,问P点的X方+Y方=?
1)圆的半径为4  
2) A+B=常数
1)p在圆上,就构成一个直角三角形。X方+Y方=4方
2)不知道XY多少,不充分    我选了A

4^4^4=2^2^X  问你X是多少     选了9

-1<X<0 ,问以下哪个最小
A  X方
D  X方-3X

一个集体有P人(已知),51%的人学习H,40%学习S,有15%的人两个都没学,问你只学H的有多少人?   第一个数字是自己编的,题意没错

旧狗补充:
83 DS:问F(x)=x-1(x+2)[(1-k)x+(x+2)] 是不是exactly 有两个解
条件1FX=0    后面还有什么忘了

2FX)含有一个因子为(X+2)方  确定

/311   DS q%pr%s比大小吧
a. 0<q<r^2<p<s^2<1
b. 0<q^2<r<p^2<s<1
举例:1/5 1/4 1/3 1/2  注意分数的平方<分数本身
条件一 pq<(rs)^2 又都是分数,所以(rs^2<rs, pq<rs 正确
条件二 (pq)^2<rs ,(pq)^2<pq, 所以pqrs大小不确定
我后来还是选A了

279 DS, 某家庭周一和周二共收到20封信,周一收到15封,周二收到5封,然后这20封信每封都会被标记为CommercialPrivate(不会标记成Both)。问从这20封信中随机抽取,有多大的概率抽到的是周二收到的,并且标记为Commercial的信件?(请大家原谅,星期一和数字有可能不对)
(1)
抽到周一收到的并被标记为Private的概率为3/5   数字是我瞎编的,反正是在扯
(2)
周二的信中有2封信被标记为Commercial 补充条件:这个数字是周一的private的两倍 注意这个东西是没用的,不要被骗了

答案B





语文 语法考点
                   to...., to ... and to平行结构
                   with独立主格做伴随表现不出时态
                  主谓一致: 主语,who....how and how ,谓语+.......  
                  XXXX was adequate to/for/that
       逻辑 考到了看了广告而来买车的人都是35岁以下那道
                某城市95年开始装了监控设备(CAMARA)来监控城市状况,但是95年的犯罪率却比94年上升了,所以得出结论,装CAMARA这个新措施没用。 问削弱    
        阅读    有三篇考到机经    一篇是导师
                                                          碳排放
                                                          还有英国法律和欧洲法律对妇女的权利保护程度不同
                    剩下那篇印象不是深,有点像某篇JJ里面讲的第三段高亮那篇。不是很懂,不误导大家了
       作文     AA  大学里面的医院治疗人的质量没有私人诊所或其他诊所好。原因1,大学里面的医院医生数量少,盈利能力低,工人工资低。原因2, 大学医院的医生经常将他的时间分成 教学,做研究和治疗病人。

加油加油~提高了还是挺多的呢!
问下你碰到的看广告来买车的问题是什么?还有选项变了没?

Finding of a survey of Systems magazine subscribers: Thirty percent of all merchandise orders placed by subscribers in response to advertisements in the magazine last year were placed by subscribers under age thirty-five.
Finding of a survey of advertisers in Systems magazine: Most of the merchandise orders placed in response to advertisements in Systems last year were placed by people under age thirty-five.

For both of the findings to be accurate, which of the following must be true?
(A) More subscribers to Systems who have never ordered merchandise in response to advertisements in the magazine are age thirty-five or over than are under age thirty-five.
(B) Among subscribers to Systems, the proportion who are under age thirty-five was considerably lower last year than it is now.
(C) Most merchandise orders placed in response to advertisements in Systems last year were placed by Systems subscribers over age thirty-five.
(D) Last year, the average dollar amount of merchandise orders placed was less for subscribers under age thirty-five than for those age thirty-five or over.
(E) Last year many people who placed orders for merchandise in response to advertisements in Systems were not subscribers to the magazine.
选E

谢谢支持!!  
看了一下题目,题目是这个没有错,但是选项不对。我昨天看是也是一开始满兴奋地,后来一看选项觉得挺陌生。选项改动了。
我想下,应该还是选买车的人不是看广告的那个选项,但是它不是这样表达的。是一个主句,定从的选项。其他选项不是很记得了,不好意思啊。

对了,想起来机经一道逻辑,测年代的那道,我是倒数几道题。当时很急,直接选了鸡骨头了,是B。
