[求助]GWD-1-13,GWD-1-14 - ChaseDream

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.

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.

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。

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。

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

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

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.

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。

五年前多少或是五年來增加多少並不重要，重要的是題目傳達出

流沙說的很對，這種題目就是造抄一遍，大概也只有conclusion有這種題目吧

以下是引用victorzheng在2004-9-23 12:06:00的发言：

i will choose "E"

同样的问题,虽说可用美观此排除法排除e选项,可是毕竟文中提到productivity的提高,不也意味着产量double和cost的降低么??

偶也是一下子就选中了E，感觉A就是原文照抄，一般原文照抄的基本都有错（偶做题的感觉），所以把帖子顶出来，请NN帮忙解答一下为什么E不对呢？

(However, original context ‘…even though no new mines have opened..’, i think, is inappropriate because, if there are more

new mines, mine companies need to hire more workers even with advanced machines, then output per miner could be constant or even lower.)

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。

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

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?

C注意是output per miner, not total output.开新矿之后，output per miner还是不变的

E如果新技术的成本也很高的话，抵消了人力成本，每吨成本可高可低并不一定就低。

发现大家做题怎么总是从好的方面去想，也要想想坏的一面啊。

看了楼上的回复，自己又想了想。觉得问题是不是出在existing，原文想表达的推理是：新技术-->导致现有煤矿产量的增加，例如T的每个矿工的产量翻了一倍（在没有新矿的情况下--这里是做一个补充说明为了使论述更严谨，其实这个完全不是此段文章想论述的内容，至于在有新矿的情况下单位产量或总产量是如何的？文章根本没有回答，自然我们无法推论出了。）故排除无关项B\C\D\E，只能选A了。

PS：最近感受，这个GWD的题目很多时候答案不是那么明确，即不是我们看了题目之后心里想到的答案，用排除法是不错的策略。

有想像力, 可是开新厂了,总的工人数就不会增加么? 不是应用新技术了吗? 新技术还会需要那么多工人吗?

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.

假设output per miner 原来是50 ，开了一家new coal mine，他的overall output 为800，有20个miners ，即output per miner为40，不但没有提高整体的，反而还降低了整体的output per miner。我的意思就是If any new coal mines had opened in Tribnia in the past five years推不出来the increase in output per miner would have been even greater than it actually was.

或者说，其实根本没必要想题目以外的东西。

Q14
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.
人均产量已经两倍，如果人没增多的话，总产量就是两倍了
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.
总产量上升可能雇的人也多了，所以人均不一定上升的。注意这里人均和总的不能对等
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.
如果有新矿开，人均产量可能上升——但是是在工人没有增加的情况下，而这点并没说明
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.
人均没上升，不一定总的也没上升
E. In Tribnia the cost of producing a given quantity of coal has declined over the past five years.
完全没提到cost的问题
