拾壹月三- ~~一站惨败~放狗

vcheung

一站惨败~~~决定再战一次,就一次...一定要把GMAT拿下!!!!!! 做题中越做越难,一直兴奋是不是自己进入了高分裤....结果......血的教训告诉我,题难未必是自己做得好,可能本来自己料不够,才觉得难!!!! 唉~~~~废话少说,开始放狗~~~为下一战积累人品!!!

作文:
AA. 讲了去年,全国的mining technology 都处于底迷状态, 但一些做renewable energy的公司都普遍挺成功的(然后列举了N个能源), 所以,有个叫Blastcom的公司决定改变策略,效仿那些开发可再生能源的公司,把自己曾经的研究都转到renewable energy上,
Blastcom 在继续采用new field strategy 获利的同时,也guarantee 未来的业绩和股票会比较稳定.

AI. With the increasing emphasis on a global economy and international cooperation, people need to understand that their role as citizens of the world is more important than their role as citizens of a particular country.

1.有一题说有害油漆和无害有漆的,反正说一公司要用,然后又说无害油漆其实和有害油漆需要的时间一样长,但花费要比有害油漆贵很多,问题是: 下面那一项假设是可以支持使用无害油漆的? (其他答案忘了,我选的是使用无害油漆可以照常工作,而使用有害油漆不行,不知道对不对~)

2. 包裹delay, 有一个快递公司发现他们有一批货被delay了, 然后就去查原因,刚好这个公司和航空公司有签协议,所以他们把错归纳给航空公司,是航空公司导致他们货物delay. 问题是: 支持这个结论的是什么? (之前看JJ里面有人选的答案是"经过这个地方的货物都是由这个航空公司负责运了". 可以我今天没有碰到这个选项,很无奈)

3. 有2个填空题......(忘记具体讲什么了)

4.还有个中国人测量喜马拉雅山什么的(内容和本月乐毒的JJ有点象,但是问evaluation的)

乐毒:
1. Lepidoptera (GWD 4题原封不动)

A smallnumber of the forest species of lepidoptera (moths and butterflies, which existas caterpillars during most of their life cycle) exhibit regularly recurringpatterns of population growth and decline—such fluctuations in population areknown as population cycles. Althoughmany different variables influence population levels, a regular pattern such asa population cycle seems to imply a dominant, driving force.  Identification of that driving force,however, has proved surprisingly elusive despite considerable research. The commonapproach of studying causes of population cycles by measuring the mortalitycaused by different agents, such as predatory birds or parasites, has beenunproductive in the case of lepidoptera. Moreover, population ecologists’ attempts to alter cycles by changingthe caterpillars’ habitat and by reducing caterpillar populations have notsucceeded. In short, theevidence implies that these insect populations, if not self-regulating, may atleast be regulated by an agent more intimately connected with the insect thanare predatory birds or parasites.

Recent work suggests that this agent maybe a virus.  For many years, viraldisease had been reported in declining populations of caterpillars, butpopulation ecologists had usually considered viral disease to have contributedto the decline once it was underway rather than to have initiated it. Therecent work has been made possible by new techniques of molecular biology thatallow viral DNA to be detected at low concentrations in the environment.  Nuclear polyhedrosis viruses are hypothesizedto be the driving force behind population cycles in lepidoptera in part becausethe viruses themselves follow an infectious cycle in which, if protected from directsun light, they may remain virulent for many years in the environment, embeddedin durable crystals of polyhedrin protein. Once ingested by a caterpillar, thecrystals dissolve, releasing the virus to infect the insect’s cells. Late inthe course of the infection, millions of new virus particles are formed andenclosed in polyhedron crystals. These crystals reenter the environment afterthe insect dies and decomposes, thus becoming available to infect othercaterpillars.

One of theattractions of this hypothesis is its broad applicability. Remarkably, despitesignificant differences in habitat and behavior, many species of lepidopterahave population cycles of similar length, between eight and eleven years.  Nuclear polyhedrosis viral infection is onefactor these disparate species share.

T-9-20:GWD-13-34:

Which of the following, if true, would most weaken theauthor’s conclusion in lines 25-30?
A.New research reveals that the number ofspecies of birds and parasites that prey on lepidoptera has droppedsignificantly in recent years.
B.New experiments in which the habitats oflepidoptera are altered in previously untried ways result in the shortening oflepidoptera population cycles.
C.Recent experiments have revealed that thenuclear polyhedrosis virus is present in a number of predators and parasites oflepidoptera.
D.Differences among the habitats oflepidoptera species make it difficult to assess the effects of weather onlepidoptera population cycles.
E. Viral disease is typicallyobserved in a large proportion of the lepidoptera population.

T-9-21:GWD-13-35:
It can be inferred from the passage that the mortalitycaused by agents such as predatory birds or parasites was measured in anattempt to
A.develop an explanation for the existence oflepidoptera population cycles
B.identify behavioral factors in lepidopterathat affect survival rates
C.identify possible methods for controllinglepidoptera population growth
D.provide evidence that lepidopterapopulations are self-regulating
E.   determine the life stagesof lepidoptera at which mortality rates are highest

T-9-22:GWD-13-36:
The primary purpose of the passage is to              
A.describe the development of new techniquesthat may help to determine the driving force behind population cycles in Lepidoptera
B.    present evidence thatrefutes a particular theory about the driving force behind population cycles inLepidoptera
C.present a hypothesis about the driving forcebehind population cycles in Lepidoptera
D.describe the fluctuating patterns ofpopulation cycles in Lepidoptera
E.    question the idea that asingle driving force is behind population cycles in Lepidoptera

T-9-23:GWD-13-37:
According to the passage, before the discovery of newtechniques for detecting viral DNA, population ecologists believed that viraldiseases
A.were not widely prevalent among insectpopulations generally
B.affected only the caterpillar life stage oflepidoptera
C.were the driving force behind lepidopterapopulation cycles
D.attacked already declining caterpillarpopulations
E.    infected birds andparasites that prey on various species of lepidoptera

2.  讲的是antibiotic和病菌的关系. 第一段说到DNA, 还说到现在的污染和一个什么病菌有关. 第二段说了两个人做的研究, 但说到底好象是一种研究. 研究从不同地方采集来的DNA.

3.云的形成. 有两个科学家研究发现了solar 太阳发出的cosmic ray 会影响cloud formation. 有三段,挺长的,看了半天没搞清楚.

4. 来不及看了,就两段,看到一个单词是Dutch就开始看题目乱选答案了. 在最后还剩15秒的时候,发现还有9题没做完,直接题目都来不及看,全部乱选.

以上认真看了的三篇阅读,我觉得都挺长的,都没看到短的,一度以为自己做得很好,没想到,这长有长的做,从来没试过有9题没做完的显现,最多也就1题,基本每次自己在家练习的时候,时间都是刚刚好,有时候还多3-5分钟出来的.以上血的教训给大家参考,说明平时自己做题的时候最好也得把时间算算好.

输血:
1. 考的是定义一个（n），表示2到n的偶数相乘，让你算（20）+（22）的最大素数因子。

答案是23原式=（2*4*6*……*20）（1+22）=23（2*4*……）

2. 参考本月JJ 195.  答案是0

3. 参考本月JJ 143. V2 有图

4. 连续5道DS题,做得我晕头转向的....

只记得那么多了,希望能帮到大家~~~
