OG18综合版CR新题全攻略

5726人学习

2018版GMAT官方指南(OG)正式发布一段时间,相信很多同学按耐不住自己激动的心情早已做过了综合版中的61道VERBAL新题,其中CR版块的个别新题也让很多同学产生了困惑,其实,这次OG18综合版新加的19道CR新题的思路与以往OG题目大体相似,并没有什么思路上的重大改变。

 

在所出问题类型中,解释题为所有问题类型中题数最多的,共7道(550,556,626,640,656,660,661),其中以填空形式出现的解释题有3道(550,626,661),削弱题有3道(546,575,627),Boldface题3道(561,599,651),普通增强题2道(589,631),评价题2道(554,643),假设增强题1道(635),结论题1道(634)。

 

因此,从问题类型入手来看,同学们应该重点关注在所有问题类型中出题数最多的解释题,而从出题考点来看,目标管理(plan题)这个考点在19道新题中占据了5道(546,554,575,589,643),分别以增强题(589)、削弱题(546,575)、评价题(554,643)的形式出现,需要同学们重点注意。

 

从做题的思路上来看,同学们仍然应该以相关性判断为核心,结合其他错误选项特征来筛选答案,对于一些跳出探讨范围的错误选项要有甄别的能力,如643题的B选项(正确答案为C):

 

The kinds of hand and wrist injuries that result from extended use of a computer while maintaining an incorrect posture are common among school children in Harnville. Computers are important to the school curriculum there, so instead of reducing the amount their students use computers,teachers plan to bring about a sharp reduction in the number of these injuries by carefully monitoring their students' posture when using computers in the classroom.

 

Which of the following would it be most useful to know in order to assess the likelihood that the teachers' plan will be successful?

 

(A) Whether extended use of a computer while maintaining incorrect posture can cause injuries other than hand and wrist injuries

(B) Whether hand and wrist injuries not caused by computer use are common among school children in Harnville

(C) What proportion of schoolchildren in Harnville with hand and wrist injuries use computers extensively outside the classroom

(D) Whether changes in the curriculum could reduce the schools' dependence on computers

(E) What proportion of schoolchildren in Harnville already use correct posture while using a computer

 

虽然有些同学认为B 选项也能对最终children是否有injuries造成影响,但是本题探讨的是extended use of a computer对hand and wrist injuries的影响关系,所以injuries not caused by computer use就属于跳出探讨范围的错误选项了。其实GMAC官方出题对这一方面的考察很多,PREP 08中有一道学生经常搞不清楚的题也与此相似:

 

Early in the twentieth century, Lake Konfa became very polluted. Recently fish populations have recovered as release of industrial pollutants has declined and the lake’s waters have become cleaner. Fears are now being voiced that the planned construction of an oil pipeline across the lake’s bottom might revive pollution and cause the fish population to decline again. However, a technology for preventing leaks is being installed. Therefore, provided this technology is effective, those fears are groundless.

 

The argument depends on assuming which of the following?

 

(A) Apart from development related to the pipeline, there will be no new industrial development around the lake that will create renewed pollution in its waters.

(B) There is no reason to believe that the leak-preventing technology would be ineffective when installed in the pipeline in Lake Konfa.

(C) The bottom of the lake does not contain toxic remnants of earlier pollution that will be stirred into the water by pipeline construction.

(D) Damage to the lake’s fish populations would be the only harm that a leak of oil from the pipeline would cause.

(E) The species of fish that are present in Lake Konfa now are the same as those that were in the lake before it was affected by pollution.

 

该题探讨的是the planned construction of an oil pipeline对pollution的影响关系,因此A选项中其他new industrial development就属于跳出探讨范围的错误选项了(正确答案为C)。

 

此外,Zora老师认为,在分析OG新题的同时,同学们也应关注到从17综合版OG中去掉的19道旧题(553,556,557,566,573,576,580,597,611,625, 632,636,643,645,648,652,656,660,665)究竟长什么样子,对于这一点的揣摩分析能够在一定程度上帮助同学们甄别考题趋势,将有限的时间与精力集中放在重点考点与解题思路上去。
