大全-8-5(OG-72)，遇到deficit我就错,请大家帮帮偶

也不知怎么的，只要题目中有deficit,budget之类的词，我就会错    现在是看到题目中有这些词，就怕怕。

M-8-5(OG 72)题目如下：

5.   Large national budget deficits do not cause large trade deficits. If they did, countries with the largest budget deficits would also have the largest trade deficits. In fact, when deficit figures are adjusted so that different countries are reliably comparable to each other, there is no such correlation.  If the statements above are all true, which of the following can properly be inferred on the basis of them?

(A) Countries with large national budget deficits tend to restrict foreign trade.

(B) Reliable comparisons of the deficit figures of one country with those of another are impossible.

(C) Reducing a country’s national budget deficit will not necessarily result in a lowering of any trade deficit that country may have.

(D) When countries are ordered from largest to smallest in terms of population, the smallest countries generally have the smallest budget and trade deficits.

(E) Countries with the largest trade deficits never have similarly large national budget deficits.

我选的是E,答案是C. 这题的结论是Large national budget deficits do not cause large trade deficits.看了大家以前的讨论，说是后面If they did,...是反证。现在我有如下两个问题：

1.怎么可以从题目infer出C呢，我感觉C是无关选项，题目既没提reduce a country's national budget,也没提lower trade deficit.而OG的解释是：The passage asserts that large budgets deficits do not cause large trade deficits. If this is so, it is possible that a country with large budget and trade deficits could reduce its budget deficit and yet retain a large trade deficit.
可是从if this is so, 怎么就可以知道it is possible that a country with large....呢？

2.E选项为什么不对呢？OG的解释是it is consistent with the passage that countries with the largest trade deficits sometimes have similarly large budget deficits (choice E)。可题目明明是说“If they did, countries with the largest budget deficits would also have the largest trade deficits. In fact, when deficit figures are adjusted so that different countries are reliably comparable to each other, there is no such correlation.”，是no such correlation啊，也就是说largest trade deficits do not have the similarly large trade deficit，不是吗？

请大家多多指教，感谢！！

这道题还是没想明白。。。。   还请大家帮帮偶，谢谢！

up up

我觉得是语气的问题  这题的结论是Large national budget deficits do not cause large trade deficits.但不排除有时会E的相反Countries with the largest trade deficits have similarly large national budget deficits.出现

C好在will not necessarily 保留了很大空间

感谢bryan的答复！

可是我还是想不明白原先的两个问题，除了语气，应该还有逻辑推理方面的原因巴，可我怎么就是看不出来呢？   请大家再帮偶分析分析下面两个我想也想不通的问题，不胜感激！！

没错,可是do not 不等于never阿 所以E因Never 可以删去

恩，对的，never太绝对了，感谢bryan！！说得真清楚    这个偶明白了

那请问(C) Reducing a country’s national budget deficit will not necessarily result in a lowering of any trade deficit that country may have.如何理解呢？好像题目并没有提到a lowering of any trade deficit呀？逻辑上是怎样推的呢？？

而OG的解释说：The passage asserts that large budgets deficits do not cause large trade deficits. If this is so,也就是如果the large budgets deficits do not cause large trade deficits, 怎么可以说： it is possible that a country with large budget and trade deficits could reduce its budget deficit and yet retain a large trade deficit.？还请多多指教的说， 谢谢！！

刚刚请教了NN,明白啦：）不敢独享，赶紧贴上：“C is basically talking about the same thing as "Large national budget deficits do not cause large trade deficits", just the opposite way.  ”说得太棒了!

XDJM, I found that in your analysis above, there is nothing concerning the last scentence---In fact, when deficit figures are adjusted so that different countries are reliably comparable to each other, there is no such correlation.

What's the function of the information provided by this scentence?

Thank you for your reply!

同意usdream MM

从做题来说，我也感觉没什么用的说~~  

看到以前的讨论，说是最后一句话是用反证法解释第一句结论。。。

Just now, I asked a friend. He said that the third scentence is just to use more detailed info to strenthen what the first scentence means. The crux is the second scentence.
