答案是A, 可是藕觉得不对。
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,所以答案A.....不知道怎么得出来的?
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.
每名矿工的生产率在5年时间内翻了一倍,所以A说如果矿工数量不变,那么总产量肯定是翻了一倍了。
总产量=矿工数量x每名矿工的生产率
每名矿工的生产率在5年时间内翻了一倍,
对,应该是这样解释。但想想这个翻倍的过程,从一倍到两倍,时间跨度是5年。可能前4年都是一倍,只最后一年发生了变化到2倍。如果是这样,即使矿工人数不遍,5年的产量也不会翻倍。
G-craker, 题目比较的只是第6年和第1年的数据,和5年中任何一年产量或累计产量等都无关吧。

对呀,是无关。这就是为什么A藕觉得不对,A讲的是5年中的产量会翻倍,藕推不出来,is there anybody elso, who can prove A is correct?
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.
你只管头管尾就行了。
原文:Coal output per miner in Tribnia is double what it was five years ago:现在每个矿工煤产量是5年前的两倍。就是说5年前是1倍,现在就是2倍。
A:Tribnia's total coal production has doubled in that period of time意思为:在这5年中,产量翻了两倍。就是说现在产量是5年前的2倍。
藕晓得的,只管头尾。Thank u, lawyer.
每名矿工的生产率在5年时间内翻了一倍,所以A说如果矿工数量不变,那么总产量肯定是翻了一倍了。
总产量=矿工数量x每名矿工的生产率
总产量=矿工数量x每名矿工的生产率*(working time/矿工)
矿工数量x每名矿工的生产率=mine的生产率
So, I think A is not really logical. Right?
我还是不懂, 而且我觉得B也没什么错的, 为什么不选,C和B比较我更倾向于B,
因为题目最后问的是 Which of the following can be properly concluded from the statement about coal output per miner in the passage,
A中没有谈到COAL OUTPUT PER MINER, 讨论的是关于Tribnia's total coal production
还有就是究竟到底如何排除C?????
归纳用排除法最方便:选项必须具备这样的特征
1>原文没有的绝对花特征;b,c,d有any,排除
2>没有的概念,如d项的cost,quantity什么的,排除,
身下只有a了.
{codestart}<SCRIPT language=javascript type=text/javascript>
document.write (usercolor('11','channing76'));

认真请教channing76:
A中的NUMBER也是原文中没有的概念啊;
而且归纳题用IF总感觉有点怪,是不是我的这种感觉不对
我也会选A,不过想多找一些选项的特征(没办法,阅读能力不行,速度慢)
各类型的逻辑题不知道有哪些选项特征.
我快考试了,多谢多谢!

Can't agree more.
I believe that C is correct because of the last sentence "Coal ouput per miner in Tibnia is double what it was five years ago, even though no new mines have opened."
What does "even though" try to emphasize here? It means that the increase would have been even greater if new mines opened, the idea that C states.
同意c
我也错选了C,但问题中提到about coal output per miner in the passage,
并不一定要选项里也有OUTPUT PER MINER, 况且C中的ANY太绝对,因为还有可能有MINE 关闭的可能啊. A比较合理是建立在一个纯粹理论的条件下的,考虑了一下还是觉得A对.
c用if条件排除法 if后的条件原文不存在直接排除
b不对 总产量=每个工人的单位产量*工人数 有可能工人人数变少呢
d的意思是:如果有任何一个矿工没有增产的话,全部的产量不会增加(要麽不变要麽减少)。——————错。因为假设其中一个矿工减产了或者没有增产,但是别的矿工大大的增产,这样的话也会导致总量不减少。
推断题最重要的还是无关词排除。
我猜想这道题ets的意图就是考控制变量。
三个变量,a=b*c,必须要有一个是定量,即有一个不变,才能对比另两个的关系。
其中b就是这个问题。每一个矿的总产量增加并不代表每一个矿工的产量增加。因为有可能是矿工人数增加了。

不是说结论中一定要有coal out per miner

觉得,BCE的问题是都探讨了原文没探讨的问题,超出了scope.不知道这个分析对不对。
B-overall output, mine和per miner的关系,原文没提及
C-new coal mine,不在原文scope
E-cost of producing,原文没提及。
D-反对了原文的前提。这个方法在OG有

c 对,
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.
文中根本没有提到 number of miners working
Coal output per miner in Tribnia is double what it was five years ago, even though no new mines have opened. 有new mines因此C 对
虽然A中没有明示Coal output per miner,但A中归纳出的结论是ABOUT每个矿工产出量的,我也开始选C,就是因为even though,但题目描述中没有说IF NEW MINES OPEN,产量就一定会增加,even though表达的也是一种可能语气,可以理解为如果新矿开工,产量没准还会更大呢。另外,Coal output per miner是由技术决定的不是吗,和新矿开工有联系吗?我也迷惑了。。。

我认为,原文even though no new mines have opened,只是告诉在没有new mines open的情况下per miner的output就double了。由这句话,不能推出new open的mine究竟是增加还是减少per miner output。
d的意思是:如果有任何一个矿工没有增产的话,全部的产量不会增加(要麽不变要麽减少)。——————错。因为假设其中一个矿工减产了或者没有增产,但是别的矿工大大的增产,这样的话也会导致总量不减少。
推断题最重要的还是无关词排除。
If any individual Tribnian coal mine has not increased
到底是指每一个(所有)还是指一个啊?
