[原创]CR快速排除选项法~~心得分享

小弟准备GMAT也有数月余

即将于下星期上战场

在此有一些CR的心得与大家分享

仅属个人意见

若有问题也欢迎各位指教!

首先

CR必须要有阅读做为强力的基础(我想大家都知道吧)

有了阅读做基础

快速排除无关选项就一点也不难了

我个人认为CR除了正确选项外

其余选项分为:无关选项,neutral选项,及相反选项(就是文章问weaken他给你support)

本帖主要探讨快速针对文章的critical point做出反应并消除错误选项

纯属个人心得

请各位指教

在这边用几题GWD的题当作例子示范:

1.         GWD-27-Q35

In polluted environments, dolphins gradually accumulated toxins in their body fat, and the larger the dolphin the more accumulated toxin it can tolerate.  Nearly 80 percent of the toxins a female dolphin has accumulated pass into the fat-rich milk her nursing calf ingests.  Therefore, the unusually high mortality rate among dolphin calves in the industrially contaminated waters along Florida’s Gulf
                            Coast
is probably the result of their being poisoned by their mother’s milk.

 

Which of the following, if true, most strengthens the argument?

 

  1. The survival rate of firstborn dolphin calves in the area along Florida’s Gulf
                                    Coast
    is highest for those whose mothers were killed before they were weaned
    .

    正确,文章说喝奶à存活率低,这里说:没喝奶à存活率高

  2. The rate at which adult dolphins living in the waters along Florida’s Gulf
                                    Coast
    accumulate toxins is no higher than that of adult dolphins in comparably polluted waters elsewhere.

    文章结论要讨论calves,这边谈adult就是irrelevant.

  3. Among dolphin calves born in the area along Florida’s Gulf
                                    Coast
    , the mortality rate is highest among those with living siblings.

    对象是calves正确了,但没有提到mother’s milk,所以也是irrelevant

  4. As dolphins age, they accumulate toxins from the environment more slowly than when they were young.

    速率显然没有提到,所以也是irrelevant

  5. Dolphins, like other marine mammals, have a higher proportion of body fat than do most land mammals.

    讲到dolphins in general,没有只讲calves,所以是irrelevant

2.         GWD-28-Q11

Trancorp currently transports all its goods to Burland
                            Island
by truck. The only bridge over the channel separating Burland from the mainland is congested, and trucks typically spend hours in traffic. Trains can reach the channel more quickly than trucks, and freight cars can be transported to Burland by barges that typically cross the channel in an hour. Therefore, to reduce shipping time, Trancorp plans to switch to trains and barges to transport goods to Burland.

Which of the following would be most important to know in determining whether Trancorp’s plan, if implemented, is likely to achieve its goal?

A: Whether transportation by train and barge would be substantially less expensive than transportation by truck.

文章结论只与时间有关,cost的多寡无须计较

文章结论只与时间有关,cost的多寡无须计较

B: Whether there are boats that can make the trip between the mainland and Burland faster than barges can

文章是讨论trains and barges, boats属于多余的推论,消除!

文章是讨论trains and barges, boats属于多余的推论,消除!

C: Whether loading the freight cars onto barges is very time consuming.

正确,谈到了critical point: 时间(time consuming)

正确,谈到了critical point: 时间(time consuming)

D: Whether the average number of vehicles traveling over the bridge into Burland has been relatively constant in recent years?

Critical point是时间, average number of vehiclesmatch!

Critical point是时间, average number of vehiclesmatch!

E: Whether most trucks transporting goods into Burland return to the mainland empty?

Critical point是时间, 有没有return不是重点!

Critical point是时间, 有没有return不是重点!

3.         GWD-28-Q9

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.  文中的结论是跟这个prevent leaktechnology有关,此选项无关

B: Other than the possibility of a leak, there is no realistic pollution threat posed to the lake by the pipeline’s construction.  正确,唯一会pollute的只有leak,所以可以prevent leak就可以prevent pollution

C: There is no reason to believe that the leak-preventing technology would be ineffective when installed in the pipeline in Lake
     Konfa这种类型的选项基本上都可以直接排除

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

Technology才是critical point, damage的种类无关

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

Technology才是critical point, damage的种类无关

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

Technology才是critical point, species无关

 

4.         GWD-28-Q16

Paper&rint is a chain of British stores selling magazines, books, and stationery products. In Britain, magazines’ retail prices are set by publishers, and the retailer’s share of a magazine’s retail price is 25 percent. Since Paper&rint’s margin on books and stationery products is much higher, the chain’s management plans to devote more of its stores’ shelf space to books and stationery products and reduce the number of magazine titles that its stores carry.

Which of the following, if true, most strongly argues that the plan, if put into effect, will not
      increase Paper&rint’s profits?

A: Recently magazine publishers, seeking to increase share in competitive sectors of the market, have been competitively cutting the retail prices of some of the largest circulation magazines.

Magazine的利润本来就少, cutting retail price会让retailer的利润margin更小,所以是support这个planmake profits!

B: In market research surveys, few consumers identify Paper&rint as a book or stationery store but many recognize and value the broad range of magazines it carries.

正确,提出原因会伤害到retailerprofitability!

正确,提出原因会伤害到retailerprofitability!

C: The publisher’s share of a magazine’s retail price is 50 percent, and the publisher also retains all of the magazine’s advertising revenue.

文章关心的是retailer profits,此选项只提到publisher profit算法,无关!

文章关心的是retailer profits,此选项只提到publisher profit算法,无关!

D: Consumers who subscribe to a magazine generally pay less per issue than they would if they bought the magazine through a retail outlet such as Paper&rint.

Subscriber已经超过文章讨论的范畴了,直接排除!

Subscriber已经超过文章讨论的范畴了,直接排除!

E: Some of Paper& Print’s locations are in small towns and represent the only retail outlet for books within the community.

此选项证明因为retailerthe only one,所以可以make profit,support选项!

此选项证明因为retailerthe only one,所以可以make profit,support选项!

 

这几个例子涵盖了support, assumption, evaluation, and weaken的题型

都是我在复习GWD的同时随机挑的

证明了GMAT大部分的CR题型

只要抓住critical point

是可以很快选出来的

建议大家总结时每一题读完先问自己:这题的critical point是什么?

然后再看选项

我相信对提升速度及准确率是会有帮助的

再加上CD上所有前辈们的心血贡献

势必杀G!

以上只是小弟一点心得

希望能对CD上的各位有所帮助!

 

Technology才是critical point, species无关

请问C为何错,没有读选项之前预想的答案是B, 可是觉得C提到了增加revenue的另一个渠道,为什么不对呢?初学者,还请多指教,谢谢!
