In Teruvia, the quantity of rice produced per year is currently just large enough to satisfy domestic demand. Teruvia's total rice acreage will not be expanded in the foreseeable future, nor will rice yields per acre increase appreciably. Teruvia's population, however, will be increasing significantly for years to come. Clearly, therefore, Teruvia will soon have to begin importing rice.
Which of the following is an assumption on which the argument depends?
No pronounced trend of decreasing per capita demand for rice is imminent in Teruvia.
Not all of the acreage in Teruvia currently planted with rice is well suited to the cultivation of rice.
None of the strains of rice grown in Teruvia are exceptionally high-yielding.
There are no populated regions in Teruvia in which the population will not increase.
There are no major crops other than rice for which domestic production and domestic demand are currently in balance in Teruvia.

这种强相关的有问题公式的,直接根据问题公式去推,像e这种拐弯抹角的没有直接提到“个人消耗”的,一般都不是最佳选项,这种题需要直接点出另一个变量:
每个人消耗*人数=rice需求总量;现在说rice总产量不变,人数变多,-》结论说就要进口了;
gap,这里默认了一个变量就是”每个人的消耗“是不变的
In Teruvia, the quantity of rice produced per year is currently just large enough to satisfy 【domestic demand】. 目前每年的大米产量刚好能满足【国内需求】
Teruvia's total rice acreage will not be expanded in the foreseeable future, nor will rice yields per acre increase appreciably. 种植面积和产量不变
Teruvia's population, however, will be increasing significantly for years to come. 人口将在未来几年显着增加。
Clearly, therefore, Teruvia will soon have to begin importing rice. 不得不开始进口大米。
问假设:
A. No pronounced (明显的)trend of decreasing (per capita** 【demand】) for rice is imminent(即将发生的) in Teruvia. (√)稻米(人均**【需求量】)没有明显下降趋势。即,默认了一个变量--”每个人的需求量“是不变的
E. There are no major crops other than rice for which domestic production and domestic demand are 【currently in balance现在的供需平衡】 in Teruvia. (×)
E. crop一定可以替代rice吗?并没有说明
C. This may suggest that new strains of rice could increase rice yields, but the argument assumes that rice
production will not increase
A imminent 与题干soon呼应 而E major crop 是balanced的不能削弱 需要进口rice
对于E,没有说明其他crop是可以替代rice的需求的!!!
major crops是新的information,assume不是加强,不需要新的information
Teruvia每年生产的大米刚够全国人民吃,未来不会增加种植面积,单位面积产出也不会提高,
在未来T的人口会剧增,因此T很快就要进口大米。问assumption
choice a, 人均消耗大米不会显著减少。correct
E中There are no major crops other than rice for which domestic production and domestic demand are currently in balance in Teruvia.,除了rice其他的农作物都没有达到供需平衡。---这句话的意思和我们通常设想的答案(这里的人以rice为主食,其他农作物不能取代它。这个作为这里的assumption很合理)这样的假设有很大的出入。其他农作物没有像目前rice一样达到供需平衡(可能是供大于需,也可能是需大于供),如果是前者还说的通,后者就完全不行了。这种带有可能性的选项排除为好
assumption 问题,取反,若取反后一定导致事件不发生,那么就是对的选项。
a中,取反,平均每人需求降低,那么文中论述不成立,此选项也是最直接的
e中,取反,有除了rice之外的其他粮食作物来平衡需求,但是这仍然不能说文中的论述就一定不会发生,并没有说有了其他粮食,rice的需求就会下降。
E 错在哪儿...
同错选E
e为什么不对
自己想的假定是 人们只吃米。。后来找了半天没找到这个选项 哭死
所以我看到e的other crops就选了,但是E是错的

imminent adj.即将发生的
做CR一定要全身心投入 整理好逻辑链之后一定要快速地理清楚逻辑链 在心里得到一个intended meaning的答案
因果推理,答案取非后反驳结论。emmm错了是因为没看懂A这个选项就直接跳过去了。本来选的是C,但是题目已经告诉了我们总的产量是不会变的。就算C说的发生了产量很高的种类的小稻,但同时也会有些产量低的呀,所以就平衡了。
知道了!推理文段 说的是今后几年里人口会增加 ,A说的imminent是现在人均需求就开始显著下降
不太懂T T 虽然人均需求降低了 但是人数增加了呀 总的需求可能还是增加的呀
原文假设人均需求不会下降=A
假设题要在原文中找信息
A和D的差异在于,A是第一层的原因,根本原因;如果A不变,那么D使用了才会产生影响;
错选D
