72. 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.

没有看懂推导的关系~~~~还有BUDGET  DEFICITS 和TRADE DEFICITS分别是什么?相关的知识是什么?谢谢~!

这是一归纳题，countries的national budget deficits 和trade deficits怎样的关系，问题比然围绕这个展开；C和结论there is no such correlation最符合。C也有national budget deficits 和trade deficits核心词。

A，to restrict foreign trade文中未说，而且是foreign。无关

B，文中未说deficit figures 的不同国家比较。无关

D，largest to smallest in terms of population ，无关

E，never 文中未提，无关。

请指教！

我还是没明白？？？？？？？？？？？？？？

文章的第2句 很CONFUSING ？如过不用排除法，怎么办？？？？？？？？？+

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.

budget deficit高并不能引起trade deficit高。否则的话，最大的budget deficit会导致最大的trade deficit。事实上，当把赤字标准化用来比较，也没有发现类似的关系。（such correlation指的就是第二句，即说了半天，只有第一句才是关键。）

Infer题肯定用排除法。（排除无关项）

只是A, B, D比较容易。

可以这么理解：

topic:        A high -/-> B high <=> A,B don't have correlation with regard to number

solution:    reduce A -/-> reduced B <=> A,B no such correlatioin

notes:     it's a loose relationship, be careful to eliminate those strict definition. therefore, E, which use 'never' should be wrong.

以下是引用hawkinsxie在2005-3-4 14:04:00的发言：

ETS对逻辑的表达竟可以如此麻烦！太绕了！ 看了半天才明白事实上做题只需要第一句就足够了。剩下的两句是对第一句否定再否定
