请教一到CR：
答案是E
没大看懂，请指教，多谢！
贴图看的不是太清楚，我把题重新贴一下：
Q16:
A diet high in saturated fats increases a person’s risk of developing heart disease.
Regular consumption of red wine reduces that risk. Per-capita consumption of saturated
fats is currently about the same in France as in the United States, but there is less heart
disease there than in the United States because consumption of red wine is higher in
France. The difference in regular red-wine consumption has been narrowing, but no
similar convergence in heart-disease rates has occurred.
Which of the following, if true, most helps to account for the lack of convergence noted
above?
A. Consumption of saturated fats is related more strongly to the growth of fatty
deposits on artery walls, which reduce blood flow to the heart, than it is to heart
disease directly.
B. Over the past 30 years, per-capita consumption of saturated fats has remained
essentially unchanged in the United States but has increased somewhat in France.
C. Reports of the health benefits of red wine have led many people in the United
States to drink red wine regularly.
D. Cigarette smoking, which can also contribute to heart disease, is only slightly
more common in France than in the United States.
E. Regular consumption of red wine is declining dramatically among young adults in
France, and heart disease typically does not manifest itself until middle age.
题目的意思是：经常喝红酒有助于减少患心脏病的危险。在法国心脏病的发病比美国少，因为他们的红酒消费量高。但现在两个国家的（人均）红酒消费量的差异已经比较小了，但心脏病发生率方面的差异却没有同样减少，问原因：
E说：在法国，在年轻人当中，经常喝红酒的人急剧减少，但心脏病通常在人到中年才显现出来。
这就说明，美国和法国红酒（人均）消费量差异的减小，可能并不是因为美国人比以前喝更多的红酒了，而是因为法国的年轻人比以前喝的少了。这样就造成美国的心脏病发病率没有减少，而由于心脏病通常在中年才显现，所以法国的心脏病发病率在短期内也没有增加，这样，两个国家之间心脏病发病率的差距并没有减少。
请NN解释下为什么B不对啊.我做题的时候答案都没看完，直接就把B选出来了
不是说过去三十年消耗量在法国是增加的，所以即使红酒喝的和美国人一样多了，两个国家之间心脏病发病率的差距并没有减少。
对 lawer_1 的解释还是不明白。俺认为 B 挺对的。
由于 对 heart disease rate (HDR)， 法国的 > 美国的，
所以 difference = 法国的HDR - 美国的HDR > 0
法国的per-capita consumption of saturated fats 增加，则法国的HDR 会增加，
difference 便会变大。正好可以解释原文的 no similar convergence in heart disease.
但是，B 中可能有问题的是 "increased somewhat in France",
somewhat 的含义很弱，常被 Ｋａｐｌａｎ 认为不是正确答案的标志。
ＮＮ 再看看吧。
原文给两个规律：FAT高HEART DISEASE也高。WINE低HEART DISEASE也低。
过去：法国（FAT一样，WINE高，HEART DISEASE低）
美国（FAT一样，WINE低，HEART DISEASE高）
现在：WINE的差别已缩小，却HEART DISEASE没缩小。
B说美国的FAT没变，法国的FAT增加点，既然法国的FAT增加，HEART DISEASE也应增加，它和美国在HEART DISEASE方面的差距应缩小。但原文要你解释的是没缩小。
看错了，原来是法国低,做题的时候看成M国低了,review的时候居然还是看成M国低
谢谢斑竹的解释..
搞清楚俺那里错了。
上次说的" difference = 法国的HDR - 美国的HDR > 0“ 不对，应该是
difference = 美国的HDR - 法国的HDR > 0
这样就可以解释了。在谢 lawyer_1 !
我明白lawyer的解释，但是题目

Per-capita consumption of saturated fats is currently about the same in France as in the United States, but there is less heart disease there than in the United States because consumption of red wine is higher in France. The difference in regular red-wine consumption has been narrowing, but no similar convergence in heart-disease rates has occurred.
而B中over the past 30 years,包含在： Per-capita consumption of saturated fats is currently about the same in France as in the United States,所以B应该与原文一致，不起任何作用。而不是起反作用。
我的理解对马？nn指教！
楼上有理，比较的时间区间不同。B可以说是无关。
A：无关推理
B：无关；或者与原文不一致
C：太笼统
D：无关
E：很tricky的选项，从另一个方面得出结论；逆向思维，有一点
The difference in regular red-wine consumption has been narrowing, but no similar convergence in heart-disease rates has occurred但现在两个国家的（人均）红酒消费量的差异已经比较小了，但心脏病发生率方面的差异却没有同样减少
第一次没读懂意思

b选项可以参考这个解释。原文结论是heart disease rate差距没有变化。而B得出的结论应该是差距减小了。所以还是E更好
请问D为什么不对？
我对D的理解:
能够导致心脏病的吸烟，在法国比在美国普遍。是不是因为slightly common，所以这个原因不足以导致结论中的现象呢？
D 乍看之下很像無關，又很有可能提供他因解釋，要特別注意這類選項..
關鍵在於結論說差距(發病率)沒變，這裡就要看，應該是美國發病率高於法國，所以這個選項如果說美國比法國來的common也可以做為解釋，還有這個比較slighty不夠好，所以d 比較方向錯誤，程度也不足
很同意lawyer的看法！我也是后来才想明白的。我做的时候也是假设了美国人喝红酒的增加了，所以e想不明白！但我还是选了e因为我觉得e是动态的！至于b，我当时的排除是因为somewhat，这个词的程度来修饰变化太轻了一点！还有就是文中已说Per-capita consumption of saturated
fats is currently about the same in France as in the United States，，，b项说三十年前，对文中的既成事实讨论一定是不对的！
E说：在法国，在年轻人当中，经常喝红酒的人急剧减少，但心脏病通常在人到中年才显现出来。

我咋做着做着就把这题当成削弱了~~

我的理解对马？nn指教！Agree!
I see.
I see.
我明白E为什么对了。可是D呢，看着是他因，绕着里面出不来了，哪位帮助解释一下，
lawyer说得对嘛，这题简单地，就是E
我第一遍也选的D,理由和前面几个朋友一样，我读题一开始就读成美国人的心脏病发病率低,正好反了，呵呵,所以发现D的排他因合适,而E在我理解是削弱
