【更新完毕，附个人整理狗】芭妖妖，北京一战720，放狗（回报CD，特别给不自信的筒子）

vitalia

Q50，V38
我根本没想到能拿到这分……没有CD就不可能~~
自学一个半月，晚些我会在在走出G困境区写下自学经验~~~
进考场之前，GWD平均错18+，prep600,650,640
第一句、感谢CD的各位童鞋！感谢共享狗子和分享资料的童鞋！！！
大家千万不要放弃，实力和我一样不好的一定要仔细分析狗狗，注意不是背，是分析。大家可以看下我的阅读狗整理方法，之前的电脑硬盘坏了，那里有个完美版的……哎，这个是比较将就的，但是思路类似。大家可以借鉴~

废话不说，上狗子
Q：遇到很多狗，其他也不难，都要好好看，陷阱很多
DS，改正一些狗子：
1，圆柱体装水那道题给了圆柱体长6F，两个条件都对 选D
2，L过（-2,2）问直线斜率，1，x轴截距是2, 2，Y轴截距是1（ms）D



PS，
1，还有卖毯子，算打折后价钱那个，不是每100个打五折，是100个以上都是打5折的，就是$10/F^2
2，密码那道题，是从0-9里选3个，从25个字母（不包括O）里选3个，不计顺序，问能组成多少个密码？ 选10^3*25^3
3，T集合里是16的负数factor，S集合是8的负数factor， T一个factor-S一个的factor 的最小值是多少 -15

V，
月度（到我传的附件里找）：1，厂商集聚效应，
                                             2， 气候变冷，
                                             3， 另一篇暂时想不起来应该是狗子里的
                                          4，黑人权利著作（在09年1月的狗里找），                          
               再提醒大家一遍，零久一月的狗一定要好好看啊！重复的越来越多！！！

逻辑，
1，大风破坏窗户和屋顶
2，X Y两种产品要是都好，分着放好卖，要是都不好放一起好卖
3，政客和记者
其他好像很多是GWD里的变体，狗咬好好看

愈发：
总体来说就一句话：平行为王！！！
我的习惯是先看主谓宾排除一般只剩两三个了，再看平行结构排除。
比GWD简单，和prep相当，个人觉得不难~~

AI，专业成功就要牺牲生活那个
AA没怎么看懂……（没错，其实我就这破实力），就是说一个啤酒厂为了增加收入提高名誉，大量生产，不管市场能不能吸收，就是个生产！author的论证过程就是一大量生产了，就怎么地了，然后就怎么地了。Furthermore，怎么地了……反正就是好。。。（对不住大家了，我记性实在不好）
--------------------华丽分割线---------------更新---------------
（注意思路，数不一定准了）（√这个是对号，不是根号啊。有些前面还有狗子的题号，是我直接从我做题的狗里复制的，答案在题前后找。。。）
1，改：圆桌周长176，铺方桌不，桌布的边要垂下10F，问桌布边长。 76
2，五个整数，里面有个错的，平均数是60，把错的换回对的80，平均数是70，问错的数是啥
3，206Sn= 1+2+3+...n,求S（2n）-S（n）n²⁺S(n)       这个我直接选了 呵呵
4，229 到时候看数四个年利率，4又7/8，5又1/8, 4又3/5, 6又1/4(数字都是凑的），注意都是percent，求the greatest difference在以下那个区间范围？A.0.1~0.5 B.0.001~0.005 C0.005~0.01其  注意是percent，所以要除以100
5，231 B  存钱进银行，年利率5%。假设中间不取出也不存入，那么3年的总收益是多少？
（1）第一年投资收益>3000 (2)第二年的利息收益是250 。
6，242√（这个是对号，我直接从我做题的狗里复制的，不是根号啊） 8个三个质数， x, y, z,他们的积有多少个factors?
7，24  A√ 11112233344，，，，问第n项是什么？
           1、bn=bn-4+bn-3(n>4)
           2、bn>bn-1
8，改正：a<b<c<d 都是整数，在线段上距离相等，问C-A .
    1. d-a=3
     2,c=2        选C
9， 44√         3的8n+2次方除以5的余数是多少？n是正整数   4
10，46 √说一个机器一开始输入的是ABCDEFG，输出一次后变成DABCGEF,其改变的方式不变，问经过至少几次又得到的输出结果又变成ABCDEFG
我选12 前面四次一循环，后面三次一循环
同意!

即就3,4的最小公倍数，为12

11，52√说是一位女士，是搞什么装修吧，装什么地板之类的。有两个包工头可以选择（注意数据不确定）：第一个包工头是每坪  0.4 dollar; 第二个包工头 500坪之内是0.X (数据既不清了)，超过500，每坪0.24dollar, 貌似问可不可以看出谁花的少
A  项目面积大于1000坪
B  项目面积小于1200坪      这题选A，沟里没答案
12，51√直角坐标系，有连点（4,0），（0,-4），经过这两点的最大的圆的直径还是半径？是多少
我选了不存在

13，改正81 √DS圆柱平放， 内长6F，里面液体高2feet，求液体体积
        1半径4feet2液体表面积24（选D）
14，118 √做一个圆，过圆上两点A、B作弦AB。D是圆上一点，C是弦AB上一点。连结CD。问：这个AB是直径吗？
(1) AC = CB。
(2) AC = CD。
答案：C。

15， 119 √求两个连续奇数的平均数是多少？

（1）至少有一个是正奇数（2）至少有一个是负奇数

选C



加上上面的数学差不多20几道了……想起来我会再写~

-------------------华丽分割线---------------传点内功给大家----------训狗方法建议----------------------------------------------
对狗子的应用向来褒贬不一，我对狗子的看法就是把它训练成自己的。

数学狗我做了三遍以上，批判的做，用原版做，用毛毛她们整理的对答案，不一致马上上论坛交流。只记思路不计数，难题单独整理，背下来。。。呵呵，另外交流很重要。我数学从小就还可以， 特别是小学奥林匹克和初中物理部分（这个和G很接近。。。。。。。囧==）

阅读狗看了四遍，其中包括整理了一遍完美版的（它死在坏了的硬盘里了），还有这个传给大家的将就版的。随时填资料很重要。

逻辑狗拿来主义~~~感谢CD，感谢霹雳狗子队~~。

语法没看狗，我只有语法底子还可以，做题时候后来一般错3个，这个我也没法传授了……语感语感。。。。G的语法考点其实不多，主要锻炼做题的感觉，平行为王。

关于狗子整理方法：（高亮。。。）
我处理狗子的方法是每天晚上固定在CD刷新，出来一个帖子就自己整理，然后和坛子里整理的进行综合。
在这个过程中，阅读狗子要自己google查资料，查相关词汇，用word07的阅读版式，里面有自带的词典，很快。
磨刀不误砍柴工，别人的资料再好，也是别人的思路~~换成自己的才踏实，整理的过程中我感觉到了一些GMAC的出题规律，所以即使做了一篇非狗的也不是那么生涩了。

记住，自己整理很重要~




时间大于一个月的童鞋可以看看我的复习经验贴……仅供参考~~~~能留给大家的只有这些了

麻烦楼主帮我看气候变冷是不是下面这篇，如果是具体是那些段？http://funnel.sfsu.edu/courses/gmo405/articles/SciAm1991.PlateauUpliftClimChng.pdf

During the past 40 million years, andparticularly during the past 15 million years, this warm, wet climate largelydisappeared. Colder climates and much greater regional extremes ofprecipitation have developed. What caused this cooling and diversification ofclimate and vegetation into a complex mosaic of many regionally distinctivetypes?

One school of though focuses onthe changing positions of the earth’s continents and oceans. The Atlantic Oceanhas expanded at the expense of the Pacific Ocean, whereas an ancient equatorialsea that extended across much of Eurasia (called the Tethys Sea) has shrunk tobecome the modern, much smaller Mediterranean Sea. In addition, the fraction ofcontinents flooded by shallow inland seas has slowly decreased, exposing largeamounts of land and creating climates less moderated by thetemperature-stabilizing effects of oceans. Computer model simulations show thatchanges in the arrangement of the continents and the size of inland seas canhave important effects on global climate over very long internvals of geologictime. But they are significantly less convincing as sole explanations for thedramatic changes of the past 40 million years.
Another possiblity is a long-term decline inthe concentration of carbon dioxide in the atmosphere, which would lessen theamount of heat trapped by the atmosphere and lead to “greenhouse cooling.” Theamount of carbon dioxide in the earth’s atmosphere over million-year timescales is controlled by two major processes. Chemical weathering of continentalrocks removes carbon dioxide from the atmosphere and carries it in dissovledchemical from to the ocean, where it is taken in by marine biota and depositedin sediments on the seafloor. Tectonic activity eventually frees this trappedcarbon dioxide, in the earth’s lithospheric plates transports the seafloor toocean trenches, where subduction carries old crust and sediments down towardthe earth’s hot interior. At great depths, the sediments melt, releasing carbondioxide, which emerges from the volcanic islands that overlie the buried curstand rejoins the atmosphere, completing the cycle.
If the pace of seafloor speading (and hence ofsubduction) slowed significantly, less carbon dioxide would be vented to theatmosphere, the atmosphere would become relatively depleted of carbon dioxideand temperatures would fall. In fact, globally averaged seafloor spreadingrates slow little or no net change in the past 40 million years. Subduction and volcanism eventually return the carbondioxide to the atmosphere, but this process requires a long time (tens tohundreds of millions of years) to complete.
Plateau uplift may alter climateby increasing chemical weathering of rocks, thereby recuding atmospheric carbondioxide concentrations. Carbon dioxide combines with rainwater and ground waterto form carbonic acid, which reacts with silicate minerals in rocks duringweathering. The resulting bicarbonate ions drain into the oceans, where theyare taken up by marine animals such as plankton and corals and eventuallydeposited on the seafloor. The net effect is that chemical weathering removescarbon dioxide from the atmosphere and locks it away at the bottom of theoceans.
Maureen Raymo proposed thatuplift of plateaus and mountain ranges has increased the rate of chemicalerosion of continental rock on the globally averaged basis. Uplift couldenhance chemical weathering in several ways. Heavy monsoons, which develop atthe margins of platueaus, unleash particularly intense rainfall. In theseregions, uplift-related faulting and folding also expose fresh rock to theweathering process. Moreover, the steeper slopes created by plateau uplift causefaster runoff, which removes erosion products and intensifies the chemicalattack on the rock. Raymo suggests that long-term uplift in Tibet and otherregions may have increased the rate at which carbon dioxide is removed from theatmosphere. In this way, concentrations would have fallen even though theamount of carbon dioxide exhaled by volcanoes (as inferred from seafloorspeading rates) remained nearly constant. Falling carbon dioxide levels wouldreduce the ability of the atmosphere to retain heat, thereby amplifying theglobal cooling.

厉害

vitalia

快考试了，沾点喜气。

另外跟lz求证：
密码那道题，是从0-9里选3个，从25个字母（不包括O）里选3个，不计顺序，问能组成多少个密码？
这个选择可以重复吗？比如说999aaa？
可以重复的话是10*10*10*25*25*25
不能重复的话是10*9*8*25*24*23

谢mm!周一就要考了，好忐忑，看见好多人平时正确率很好的，考完也才600+，不知道为什么啊~希望像楼主这么好运啊！沾点喜气！

只是举例告诉怎么循环的 没说那个算一次 我数学93% 有错题 你再讨论下吧
