Question

14．A study showed eating even a little less salt could greatly help the heart．The study was published in the New England Journal of Medicine．The scientists used a computer model to predict how just three grams less salt a day would affect heart disease in the United States．
The scientists said the results would be thirteen percent fewer heart attacks，eight percent fewer strokes （中风），four percent fewer deaths and eleven percent fewer new cases of heart disease（710C．Researchers said it could prevent one hundred thousand heart attacks and ninety-two thousand deaths every year．The researchers were from the University of California，San Francisco，Stanford University and Columbia University．They and public health professionals in the United States are interested in a national campaign to persuade people to eat less salt．（72）B．
However，some scientists say such a campaign is an experiment with the health of millions of people．
Michael Alderman is among the critics（批评家）．He is a high blood pressure expert and professor at Albert Einstein College of Medicine in New York．Doctor Alderman says that eating less salt results in lower blood pressure．（73）G．
And he says salt has other biological effects．He says calling for reductions in the national diet could have good effects，but it could also have harmful results．
Another critic is David McCarron，a nutrition and kidney （肾） disease expert at the University of California．He and his team looked at large studies of diets in thirty-three countries．（74）F．Most of them eat more salt than American health officials advise．
Doctor McCarron says the worldwide similarity suggests that a person's brain might decide how much salt to eat．
Both Doctor McCarron and Doctor Alderman have connections to the Salt Institute，a trade group for the salt industry．Doctor Alderman is a member of an advisory committee．（75）A Doctor McCarron is paid for offering scientific advice to the Salt Institute．

A．But he says he receives no money from the group．
B．Such campaigns are already in place in Britain，Japan and Finland．
C．And two hundred forty billion dollars would be saved in health care．
D．They say people eating less salt have equal chances to have diseases．
E．And it may also result in fifteen percent increase of the kidney death rate．
F．They found that most people around the world eat about the same amount of salt．
G．But he says studies have not clearly shown that lowering salt means fewer heart attacks or strokes．

Answer 1

分析 本文论述了美国人的摄盐量的多少与健康之间的关系，作者在本文客观的叙述了两种不同的观点，一是摄盐量太多可能给人们的健康带来一些问题，引起中风及心脏病等，所以有些人就提倡少吃盐．而另一观点认为如果摄盐量控制的太低，人们容易得血压低，他们说研究并没有表明少吃盐能够降低心脏病和中风的机率．

解答 CBGFA
71．C．前面一句The scientists said the results would be thirteen percent fewer heart attacks，eight percent fewer strokes （中风），four percent fewer deaths and eleven percent fewer new cases of heart disease主要是描述的少吃盐带来的各种好处，那么接下来就要叙述由此带来的财政上的节省；故选C．
72．B．前面提到a national campaign to persuade people to eat less salt，在美国全国范围内倡导少食用盐的运动，那么B项Such campaigns are already in place in Britain，Japan and Finland介绍其他国家的情况与此一脉相承；故选B．
73．G．根据开头一句及Doctor Alderman says that eating less salt results in lower blood pressure可知，本段主要介绍对以上观点的反对看法，所以G项中的没有证据表明低盐并不意味着患中风或者心脏病的风险降低；故选G．
74．F．由后面一句Most of them eat more salt than American health officials advise可知，这是叙述这些国家的人们食用食盐的数量比美国专家建议的量要多，所以F项与此意思相吻合；故选F．
75．A．本段提到了两个专家McCarron和Alderman，后面提到Doctor McCarron is paid for offering scientific advice to the Salt Institute，由此可推知另外的一名专家没有得到回报；故选A．
