标题: GWD 17-19

Q19:

A diet high in saturated fats increases a person’s risk of developing heart disease. Regular consumption of red wine reduces that risk. er-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?

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.

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.

Reports of the health benefits of red wine have led many people in the United States to drink red wine regularly.

Cigarette smoking, which can also contribute to heart disease, is only slightly more common in France than in the United States.

Regular consumption of red wine is declining dramatically among young adults in France, and heart disease typically does not manifest itself until middle age.

答案E

我选D

为什么D错？

题目已经说了The difference in regular red-wine consumption has been narrowing，E选项我觉得会让人有很多种理解。

我认为题目问的是“why no similar convergence in heart-disease rates has occurred, while the difference in regular red-wine consumption has been narrowing?"

所以一定答案一定要跟葡萄酒也有关系。这样看的话，D是无关选项。

The difference in regular red-wine consumption has been narrowing, but no similar convergence in heart-disease rates has occurred.这句麻烦帮翻译一下？

两国红酒消费量的差距缩小了，但心脏疾病的比率差并没有随之发生相应的缩小（convergence是集中，收敛的意思，可以理解成比率缩小了）

我是这样理解的。讨论一下。

D选项不正确，如果法国抽烟的人多，患心脏病的人就应该更多，两个国家就更应该缩小。

如果是美国抽烟的人多了，则正确

对,D刚好说反了,convergence 我查字典是集中收敛的意思,我想问问 LACK of convergence 是什么意思.
