也放几只狗吧

考试当天换库，猫了个咪的，看来之前GMAC发错的信不是空穴来风，当时就有预感，结果还是赌输了。
Q50V27

作文：
AA-那个Muscle Monthly 杂志上印健身运动员使用某健身器材照片，杂志很快售光，然后就有人建议新建的健身中心也应该使用这种器材，从而提高居民的身体素质。

AI- The best teachers are those who expect students chanllenge popular ideas rather than accept these ideas.

写完作文狗主还屁颠屁颠的觉得没换库呢，结果……悲剧就这样发生了


数学：
1：一个立方体和一个平面相交，问相交的部分有可能是什么形状？1、一条直线、2、正方形、3、等边三角形、4、等腰直角三角形、5、长方形。狗主答案：E 1235

2：长方形四个顶点坐标(0,0),(0,4),(7,4),(7,0)，有一条直线过点(2,2)，这条直线将长方形分成相等的两部分，问这条直线的斜率？狗主答案：A 0

3：沙子和一种什么东西均匀混合物共10 kilograms，其中沙子30%，另一种东西70%，问从这堆混合物中取出多少然后替换成纯的沙子可以使替换后的混合物沙子和另种东西各占50%？狗主答案：B 2.9

4：给了个图形，两个直角三角形，应该是全等的，两条斜边重合，这样构成一个四边形，告诉了这条重合的斜边的长度是6，然后告诉了其中一个角是60度，求这个四边形的面积？狗主答案：C 9倍根号3.

5：2^100-2^96 最大的prime factor?狗主答案：D 5

6：有30个顾客给一项服务评分，有四个等级，1234，给了一个柱状图，评1的有4人，评2的有11人，评3的8人，评4的有7人，（从图形中可以很容易看出来），问所有30个评分的median?狗主答案：C 2.5

7：AB两地距离600KM,一摩托车通常的速度都是60KM/hour，有一次这个摩托车以20KM/hour的速度行驶了一段距离，其他部分就都是以平常的速度行驶，问这次以平常速度行驶了多长时间使得平均速度为500KM/hour?

8：DS题：给了一个图形，一个正方形，里面有一个圆形，圆心和正方形的中心重合，圆和正方形不相切。正方形四个角分别有四个小矩形，小矩形四个顶点中的一个在圆上，其他就都和大矩形的角重合了，哎……这语言表达，回头还是画个图吧

阅读：
1、服务业发展与其他产业发展的关系。P1:当前各个国家的服务业都在高速发展。在发达国家，服务业的发展通常都伴随着制造业的衰退。而在发展中国家，特别是在亚洲，则可以服务业与制造业同时高速发展。P2:以印度、巴基斯坦、斯里兰卡为例说明这种情况的原因。一个原因是随着人们收入的提高，品味和习惯都发生了改变，用在必需品的支出所占比例在减少。（好像也解释不了呀，狗主有点混乱了）。另一个原因是农业仍然占经济的很大比重，这对制造业和服务业都有好处。好像就两段。

2、讲一个什么超新星的，越年轻，spin的速度就越快，随着年龄变老转的越来越慢，然后提到一个什么beam star什么的，好像有些不同，后来就解释这种不同。

3、讲白蚁nest的一些通道(tunnal?),这些通道可以交换巢穴与外界的空气，从而调节巢穴的humidity,氧气、还有温度什么的（这里有一道except题，就是问哪一个不能通过这些通道调节），只记得这点细节，整体结构没印象了

4、第四篇实在不记得了，好像挺难的，一堆生词，读完第一段完全不知道在说什么，就知道这篇让他去吧。

逻辑和语法：
只分别记得一道貌似Prep的原题
逻辑是一个地方蹲监狱的犯人比以前多，有人就说是因为现在犯罪和判刑的人多了，问weaken? 应该是之前判的刑期都比较长。
语法是一个地方的降雨量，30%怎么样，the balance 什么什么flow那个，大家可以找一找。

暂时想到这么多，想起来再补充吧。感觉整个V部分就是再被GMAT蹂躏，三站了居然赶上当天换库，还没有上次高呢，作为在职爸爸，复习时间实在有限，除了考试当天重来还没请过假专门复习，周末还要抽时间陪孩子，也绝对算是CDer中的高龄了，只求700+, 现在有些失落，求安慰，第一时间来放狗，希望可以帮到后面考得童鞋，然后都过个好年。

语法那个，是这题吗？
The continental United States receives an average of 30 inches of precipitation a year; transpiration from soil and from plants returns approximately 21 of the 30 inches to the atmosphere, while the balance of 9 inches contributes to the flow of streams and rivers.

(A) transpiration from soil and from plants returns approximately 21 of the 30 inches to the atmosphere, while the balance of 9 inches contributes to the flow
(B) even though transpiration from soil and from plants returns approximately 21 of the 30 inches to the atmosphere, the remainder of 9 inches contribute to the flowing
(C) although transpiration from soil and from plants return approximately 21 of the 30 inches to the atmosphere, the balance of 9 inches contribute to the flowing
(D) with transpiration from soil and from plants to return approximately 21 inches to the atmosphere, the rest of the 9 inches contributes to the flow
(E) as transpiration from soil and from plants return approximately 21 of the 30 inches to the atmosphere, the rest of the 9 inches contribute to the flow

选什么呢？

那选什么呢？

第七题应该是9个小时吧？

设用20KM/H先跑了X小时，再用60KM/H跑了Y小时，则总共跑了X+Y小时，有：
20X+60Y=50(X+Y)
得到3X=Y;
有因为总距离是600，所以50(X+Y)=600，求得X+Y=12
得到X=3，Y=9
