1、以下是一位考生参加完2012年10月21日的新GRE考试之后总结的少量新GRE机经回忆，机经的作用十分重要，希望各位考生看完后能够受到一些启发，认真备考，获得理想的成绩。2012-10-21 成都电子科技大学 V156Q166分数很一般，撸主之前看了很多机经，特别是托福的机经三次speaking和writing都中了，所以来回馈一下。虽然这次Verbal没中一个或者我没看到。ISSUE:5 Claim: Governments must ensure that their major cities receive the financial support they need in order

2、 to thrive.Reason: It is primarily in cities that a nation's cultural traditions are preserved and generated.Argue:17、The following appeared in a memorandum from the manager of WWAC radio station."To reverse a decline in listener numbers, our owners have decided that WWAC must change from i

3、ts current rock-music format. The decline has occurred despite population growth in our listening area, but that growth has resulted mainly from people moving here after their retirement.

4、 continuing decline in local sales of recorded music suggests limited interest in music. Instead we should change to a news and talk format, a form of radio that is increasingly popular in our area."数学：1.n和m都是正整数，m是26的一个因子，问所有整数中，能同时和3n，(26/m这两个数相等的个数最多是多少?因为3n是3的倍数，而(26/m只含有因子2，所以不可能整数同时和这两数相等

5、，选0个。2. 一个立方体中放了一个圆柱，圆柱底面内切于立方体底面，高和立方体相同，问体积比最接近的值。答案：3：43.K<2，问在1,2,3,k,2k中，有可能成为中位数的有哪些?答案 1,2，2k4.一个人骑车，上坡15miles/hour的速度骑了5miles，然后下坡5miles，问下坡速度多少才能使平均速度达到20mile/hour。答案30miles 这题不能简单的20*2-15=25，因为上下坡的时间不一样，平均速度不可能是上坡速度+下坡速度除以2，要按照 “速度=路程/时间”严格推。5.有3个数列，分别有X,Y,Z个数(xyz都是奇数，这3个数列中位数都是52，问把这三个

6、数列合并后的中位数，和52比较。答案：相等。貌似就没什么难题的。填空：1.minor misgivings 一个作者的观点还是作品， critics of this authors acclaim that。 is thoroughly_ 选项1.absurd 2.understandable 我选的的absurd。2.国会在做决定时一般都会听取大多数人的意见以为他们担心失去大多数的支持，如果一个没得到大多数人支持的决定没起到应有作用，就会引起政治冲突。三空题， 第一个是听取意见，第二个担心(fear of，第三个引起冲突 具体单词忘了3.一个正向重复的题，number of XXX 会_ t

7、he rate of OOO，因为 the greater of XXX， the more increase of OOO， 我选的accelerate，还有一个词没选出来，另外5个单词都没看出有accelerate的意思4.一个叫S的地方被认为是britain的首先建立的city， 但是后来发现在britain 的其他sites 发现了比S更早的证据，。(不记得了三空题，就记得第一个控established as其他单词：deplorable，阅读：1.一个作家以高雅的描绘而著称，但是却忽略了她subject to matters的特性。她总是被认为描写一个高雅的东西，但实际上她描写了很多

8、穷人和下等阶级。2.科学家一直认为comet 上的温度是零度，(转折但是新的发现通过2个技术(有题，3选2，选这2个技术觉得温度不会是零度， (再次转折， 很多astronaut 坚持认为是零度，并且反驳这个新的发现。3.长篇(4道题：全球变冷，which is result from the same reason of 全球变暖(有题，答案就是全球变暖和全球变冷都来自一个原因，好像原因就是二氧化碳，然后又说全球变暖主要是在晚上和冬天，而全球变冷体现在past 40years 的day time temperature 下降了0.5度(有题。第二段是全球变冷地球whole 变冷，而是bala

9、nce the temperature between 一个地方 with 另一个地方，然后说全球变冷在中高纬度的北美地区是different的(有题。第三段讲什么忘了。4. 森林化减少二氧化碳，通过重新种树，或者在以前没树的地方种树来森林化，但是通过这2个技术产生的森林是vulnerable的，然后又说森林的bettles，因为气候warm了，所以更多，更活跃，产生更多的二氧化碳(有题，然后又说第二种技术会涉及到很多其他的阻碍因素，比如农民选择什么样的树来种植，怎么样来栽培，还有经济利益，政策等等。(农民种树这个地方有题。补充一下 森林化那篇是JJ。文章如下：Globally, the co

10、mbination of reforestation and afforestation activities could reduce atmospheric CO2 concentrations by as much as 30 parts per million (ppm this century (House et al. 2002. However, this potential mitigation is limited by many factors. One is the vulnerability of forests to increased disturbances, i

11、ncluding those caused by pathogens, droughts, fires, and storms (Galik and Jackson 2009. For example, the mountain pine beetle is projected to convert 374,000 square kilometers (km2 of pine forest from a small net carbon sink to a large carbon source in Alberta alone, liberating 1 billion tCO2e to t

12、he atmosphere (Kurz et al. 2008. Climate change is another factor that could limit the potential for carbon sequestration in forests. The mountain pine beetle in Alberta is thriving in part because of warmer minimum temperatures in the winter and warmer and drier summers. A third potential limitation is landowner behavior in private-sector forestry, including decisions on what species to plant and how intensely to manage forests. Private forestry competes economically with agriculture, urban development, and other land
