Question

【題目】閱讀理解
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（鈉攝入量）increased the risk of stroke（中風(fēng)）,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, “l(fā)ow 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.

（6）B
【解析】這是一項研究發(fā)現(xiàn)：鹽吃少了對人體有害。但是也有人持相反的觀點。
⑴細(xì)節(jié)理解。根據(jù)第一段 low sodium intake increased the risk of stroke（中風(fēng)）,heart attack and death.可知鹽吃少了會增加中風(fēng)，心臟病和死亡的危險。故選A。
⑵詞義猜測。句意：研究進(jìn)一步表明，只有有可能患高血壓和食物中含高鈉的人應(yīng)該擔(dān)心在飲食中……鈉的攝入。support支持；provide提供；cut down削減；spread傳播。故選C。
⑶細(xì)節(jié)理解。題意：門特的研究建議……人中減少鹽的攝入。文章第二段第一句說只有患高血壓和食物中含鹽量高的人需要減少鹽的攝入，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中國和中亞地區(qū)人們的平均鹽的消耗很高，所以選B。
⑷細(xì)節(jié)理解。根據(jù)第二段提到 The study also doubts the correctness of the present guidelines that suggest low salt intake for everyone可知這項研究懷疑現(xiàn)行的建議人人少吃鹽的指導(dǎo)方針的正確性。故選D。
⑸細(xì)節(jié)理解。根據(jù)最后一段“The study does not correctly measure sodium intake, and it should not make Americans stop worrying about salt.可知他認(rèn)為門特的研究沒有正確的測量鹽的攝入量，不應(yīng)該讓美國人停止擔(dān)心鹽的危害。故選A。
⑹主旨大意。根據(jù)第一段可知本文介紹門特對于低鹽飲食的新發(fā)現(xiàn)。故選B。
