18号裸考 一些记忆

北拳猪猪

结果不好，不说了，现在努力回忆了一些，希望有帮助

作文

AA不说了..也没有什么难度，AI是224里的第33题，People are likely to accept as a leader only someone who has demonstrated an ability to perform the same tasks that he or she expects others to perform.

数学

1.一个倒L型的东西，求面积。给出短的竖边是15，长的竖边是35.短的横边是20，长的横边是40.我算出来1000

2.一个等边平行6边形，顺时针ABCDEF鱼鳞型，周长42，给出角AFC是60度，求BD长。我算出来7根号3

3.给了一个定义说，具体忘记了..我随便举例吧..譬如12345，那么N=1+2+3+4+5=15=1+5=6,反正就是每个数字相加，加出来以后如果是超过2位数的再相加，直到是个位数为止。题目里面给了一个50654吧..我记得..然后问有多少个2位数和这个50654有一样的结果..就是多少个两位数个位和十位相加等于20。我算出来是10个。11，20，29，38，47，56，65，74，83，92

4.3个机器同时做要20小时，a单干要240小时，b单干要40小时，问c单干要多久，我算出来是48小时

5.问1+根号2是下面那个式子的根，貌似有网友提出来过了..

6.n是2-29所有质数的product加1,问1.n可以被2-29里面的某个质数整除么？2.n可以被大于29的质数整除么？3.n可以被30整除么？

7.DS：（0，2）和（2，0）在一个圆上，问圆的半径。a.忘记了..b.是半径不大于2根号2

这道题，回来我看了2007/12月的寂静，有道差不多的，大家议议吧

“24. JJ过(-4,0),(4,0)的圆半径是多少?
我选无限大
正确，不在同一直线的三个点才能确定一个三角形，固定的三角形才有一个外接圆
Key: 无限大”

8.用x miles/h走1miles，如果用x+20 miles/h走1miles可以省4分钟，问x是多少。我算出来是10

9.DS:f(n)=ax^2+bx+c问ab>0? a.f(1)=0 f(-1)=0 b.af(1)f(-1)=0

其他的我再想想

语法：

1.enthusiastic about
2.preference toward and likeihood of
3.because和because of
4.each

逻辑：
全忘了..我都来不及看，就记得一道是说车票的什么20块优惠，后来建议10块就可以优惠，这个不知道是哪里了..反正以前也做到过

阅读：
我在其他帖子里跟过了
1.一个是说industrial art的
2.1870-1930 american apple transaction.
3.是说美国电信业务，AT&T拆分什么的..pace太差，来不及看..还有一篇暂时想不起来

新增：
数学
10.一个圆柱体直径是6，高是10，然后自重是12g吧...然后说往里面灌水。一个立方的水是0.6g，问灌满是以后接近哪个数。

阅读
4.是说一个关于地震的。说通过加长对建筑的波长可以有效减低地震对建筑的破坏。具体的实在是想不起来了
里面有一个问题是，说如果这篇文章的标题是XXX，那么小标题是什么..

LZ的问的好···OA是WHAT？

winner2010

多谢LZ啦！！！

另外，忘记还从哪里看来一道狗狗～ google一下貌似应该是这个。真是对不住，忘记了提供狗狗的好心同学不说，还忘记了整理了狗狗的那个帖子。。。今天真是太急了。。。马上就考了。。。只能贴在这里，希望要考了的同学们看到！

不过不确定哦～

In the past, most children who went sledding in the winter snow in Verland used wooden sleds with runners and steering bars. Ten years ago, smooth plastic sleds became popular; they go faster than wooden sleds but are harder to steer and slow. The concern that plastic sleds are more dangerous is clearly borne out by the fact that the number of children injured while sledding was much higher last winter than it was ten years ago.

Which of the following, if true in Verland, most seriously undermines the force of the evidence cited?

A. A few children still use traditional wooden sleds.
B. Very few children wear any kind of protective gear, such as helmets, while sledding.
C. Plastic sleds can be used in a much wider variety of snow conditions than wooden sleds can.
D. Most sledding injuries occur when a sled collides with a tree, a rock, or another sled.
E. Because the traditional wooden sled can carry more than one rider, an accident involving a wooden sled can result in several children being injured.

答案好像是有争议的。OA好像是B。但是很多人选C的。

OA是哪里来的?哪家OFFICIAL机构给的啊?

这条题目,题目里讨论的是smooth plastic sleds,所以选项C的讨论范畴与题目的相符.

B可以视为无关答案.小孩是否穿保护衣服与他们用PS是否会受伤无关,你不要自己加上假设说"哦,小朋友穿了protective gear,所以他们受伤少了",谁告诉你的啊?万一他穿了protective gear,但是却撞到脑袋呢?难道你能说他没受伤吗?B明显是"王顾左右而言他"的选项.这种选项在GMAT CR里很多,仔细体会一下,他们都是错误选项的样子.

我觉得是C，B的话说明使用wooden sleds和plastic sleds的children也都不带保护镜什么的，没有undermine,我觉得它的作用更像去strengthen argument的一个assumption. 望指教

事故增多 和 popular 也有关 但并不是说一定就更危险

但是B如果是真的的话 那就是说在同等test subjects情况下 P比W危险
C是进一步增强popular

觉得还是C
