Question

【题目】阅读理解
Low-salt diets are actually harmful to our bodies, a recent study found. The scientists, led by Andrew Mente of McMaster University, found that no matter whether one has high blood pressure or not, low sodium intake（钠摄入量）increased the risk of stroke（中风）,heart attack and death.
The study goes on to suggest that only certain people who are likely to get high blood pressure and who eat food with high levels of sodium should be worried about reducing sodium intake in their diets. McMaster university's Martin O'Donnell,the study's co-author, said in May 2016,“This study adds to our understanding of the relationship between salt intake and health. The study also doubts the correctness of the present guidelines that suggest low salt intake for everyone.”
Mente added, “low sodium intake reduces blood pressure in some degree, but it also has other effects.” In the McMaster University study, the researchers considered a high level of sodium consumption（消耗） to be over 6 grams every day. Mente pointed out, “This shows that many people around the world are taking in healthy amounts of salt.” Mente did not agree with the present guidelines on reducing sodium intake in almost all countries. However, he would accept efforts to reduce salt intake in some areas, such as China and Central Asia, where the average salt consumption is unusually high.
However, Elliott Antman, past president of the American HeartAssociation(AHA) was angry with Mente's study. “The study does not correctly measure sodium intake, and it should not make Americans stop worrying about salt. The American Heart Association continues to suggest less than 1.5 grams of sodium each day from all sources,” he said.

【解析】这是一项研究发现：盐吃少了对人体有害。但是也有人持相反的观点。
⑴细节理解。根据第一段 low sodium intake increased the risk of stroke（中风）,heart attack and death.可知盐吃少了会增加中风，心脏病和死亡的危险。故选A。
⑵词义猜测。句意：研究进一步表明，只有有可能患高血压和食物中含高钠的人应该担心在饮食中……钠的摄入。support支持；provide提供；cut down削减；spread传播。故选C。
⑶细节理解。题意：门特的研究建议……人中减少盐的摄入。文章第二段第一句说只有患高血压和食物中含盐量高的人需要减少盐的摄入，在第三段最后提到reduce salt intake in some areas, such as China and Central Asia, where the aver age salt consumption is unusually high中国和中亚地区人们的平均盐的消耗很高，所以选B。
⑷细节理解。根据第二段提到 The study also doubts the correctness of the present guidelines that suggest low salt intake for everyone可知这项研究怀疑现行的建议人人少吃盐的指导方针的正确性。故选D。
⑸细节理解。根据最后一段“The study does not correctly measure sodium intake, and it should not make Americans stop worrying about salt.可知他认为门特的研究没有正确的测量盐的摄入量，不应该让美国人停止担心盐的危害。故选A。
⑹主旨大意。根据第一段可知本文介绍门特对于低盐饮食的新发现。故选B。
