[求助]GWD-1-13,GWD-1-14

今天第一次来逻辑区问问题,只因为被GWD真题逼急了,错误率差不多一半了,打击得要命,如果问了些弱智问题,大家多多包涵~:


Q13:
In the United States, of the people who moved from one state to another when they retired, the percentage who retired to Florida has decreased by three percentage points over the past ten years.  Since many local businesses in Florida cater to retirees, this decline is likely to have a noticeably negative economic effect on these businesses.


Which of the following, if true, most seriously weakens the argument?


A. Florida attracts more people who move from one state to another when they retire than does any other state.
B. The number of people who move out of Florida to accept employment in other states has increased over the past ten years.
C. There are far more local businesses in Florida that cater to tourists than there are local businesses that cater to retirees.
D. The total number of people who retired and moved to another state for their retirement has increased significantly over the past ten years.
E. The number of people who left Florida when they retired to live in another state was greater last year than it was ten years ago.


这道题答案D,可我选C。我觉得既然结论是经济会收到影响,那说还有其它经济撑着不是挺好得削弱吗?而D仅仅说退休并移居的人增多了,并不代表就移到Florida啊,况且原文已经说了移来Florida的人少了,那这个也就起不了什么作用了吧。我哪里想错了?


Q14:
That the application of new technology can increase the productivity of existing coal mines is demonstrated by the case of Tribnia's coal industry.  Coal output per miner in Tribnia is double what it was five years ago, even though no new mines have opened.


Which of the following can be properly concluded from the statement about coal output per miner in the passage?


A. If the number of miners working in Tribnian coal mines has remained constant in the past five years, Tribnia's total coal production has doubled in that period of time.
B. Any individual Tribnian coal mine that achieved an increase in overall output in the past five years has also experienced an increase in output per miner.
C. If any new coal mines had opened in Tribnia in the past five years, then the increase in output per miner would have been even greater than it actually was.
D. If any individual Tribnian coal mine has not increased its output per miner in the past five years, then that mine's overall output has declined or remained constant.
E. In Tribnia the cost of producing a given quantity of coal has declined over the past five years.


答案为A,但C和D为什么conclude不出来?

1.注意最后一句中的these businesses指的是business catering to retiree,所以C说更多的商业是针对旅游者的对削弱结论并无关系

2.关于归纳题的做法MM还需要看看基本的知识,注意归纳只能是从题目中现有的条件里归纳出来,不能随意增加新信息也不能有超过原文的假设和附加条件

我也是个新手,但是前面的题d显然是对的。percentage decrease,如果对结论影响削弱只能是总数增加。这样可以削弱比例下降的作用。

我认为14题好像D更有道理,题目中提到“even though no new mines have opened.”那么,如果每个矿井的产量不增加的话,总的产量当然会降低,而D正式说明了这个问题呀,为什么不对?

Q14

结论是:引进新技术提高生产力,条件:Tribnia's coal industry引进了新技术,Coal output per miner in Tribnia  提高了,在没有增加新矿的情况下,

我认为:D是可以直接排除的,因为文中没有提到任何individual mine的信息。

关键是A和C。

A是个比较隐蔽的答案,arundhati,你有没有发现,conlusion的难题都是用一些抽象的词或是概括的话去代替原文中的名词,想造成是新信息的假象,使的我们一看就排除。其实就是答案,我想是老美可能就不存在这种障碍了。这题也是同样的,工人数不变就是没有开新矿的代名词。

这样选项很符合题目的意思,新矿的数不变,output 增加。这个是文中给的事实,和逻辑关系

C。缺少一个条件,technology,题目是technology和new mine两个条件给出的 increase,所以,只给一个条件发生变化,而没有给出另外一个条件的情况,我们不能得出准确的判断

     to solve the first question, you should pay very attention to" percentage" and the total number

     if the overall number of retirees was largely increased, the fact that the percentage of retirees to Florida decreased do not indicate that the declining of the number of retirees to Florida . D is the right answer

     C can not weaken the argument. even if tourists are more preferable to local business, it is obvious that the decrease of the retirees to Florida has a negative economic effect on these businesses. C is wrong

     Q14

      i think the right answer can not include additional information that do not presented by the passage

      so C and D is obvious wrong

14题我想了半天还是没敢选A,因为它和原文就是一样的嘛。现在看起来不要把ETS想的太高明了。

regard to the tribnia' coal industry question, i think i will choose "E" ."E" said the cost of producing given quatity of coal had been declined during the pass five years. that virtualy conclude all the passage. well, the meaning of the passage was, due to the adoption of new technology, tribnia' coal industry doubled the output without any new existing miners. so in other word, cost per quatity should had decreased.

i will choose "E"

14题,题干中这句话怎么理解??

Coal output per miner in Tribnia is double what it was five years ago

藕觉得她只是说现在的生产率是5年前的两倍,过去5年间的生产率是多少无从而知。
