3.C(文中应是正能量，C项与传递正能量不符，“都着唐装”不能算是抄袭，该评论属于炒作、吸引关注、骗取量的行为)
In recent years, there has been a steady attack on salt from the doctors: salt is bad for you—regardless of your health. Politicians also got aboard. “There is a direct relationship,” US Congressman Neal Smith said, “between the amount of sodium(钠) a person consumes and heart disease, circulatory(循环的) disorders, stroke and even early death.”
Frightening, if true! But many doctors and medical researchers are now beginning to feel the salt scare has gone too far. “All these remarks and cry about salt is unnecessary,” Dr. Dustan insists. “For most of us it probably does not make much difference how much salt we eat.” Dustan’s most recent short-term study of 150 people showed that those with normal blood pressure experienced no change at all when placed on an extremely low-salt diet, or later when salt was reintroduced. Of the hypertensive(高血压的) patients, however, half of those on the low-salt diet did experience a drop in blood pressure, which returned to previous level when salt was reintroduced.
“An adequate to somewhat excessive(过度的) salt intake has probably saved many more lives than it has cost in the general population,” said Dr. John H Laragh. “So an opinion that the whole population should avoid salt makes no sense.”
Medical experts agree that everyone should practice reasonable “moderation”(节制) in salt consumption. For the average person, a moderate amount might run from four to ten grams a day, or roughly 1/2 to 1/3 teaspoons. One to two grams of salt would come from the natural sodium in food. The rest would be added in processing, preparation or at the table.
“Na is not your enemy,” says Comek’s Dr. Laragh. “Salt is the No.1 natural component of all human tissue, and the idea that you do not need it is wrong. Unless your doctor has proven that you have a salt-related health problem, there is no reason to give it up.”
1.Why is salt attacked by doctors and politicians?
A. It’s unnecessary.
B. It does no good to human health..
C. It is hated by most people.
D. It will surely lead to heart disease and circulatory disorders.
2.From Dr. Dustan’s study in Paragraph 2 we can infer that _____.
A．a low-salt diet may be good to some patients
B．the amount of salt intake has nothing to do with one’s blood pressure
C．the reduction of salt intake can completely cure a hypertensive patient
D．an extremely low-salt diet makes no difference to anyone
3.In the 3rd paragraph, Dr. Laragh implied that _____.
A．people should not be afraid of taking much excessive salt
B．doctors should not always advise people to avoid salt
C．an adequate to somewhat excessive salt intake is suggested to ill people
D．excessive salt intake has killed some patients in the general population
4.What is the experts’ advice for average people on salt consumption?
A．They should increase salt intake through sodium pills.
B．They should avoid salt as often as possible.
C．They should consume 1/2 to 1/3 teaspoons of salt a day.
D．They needn’t care about how much salt they consume.
试题答案
1.B
2.A
3.B
4.C
【解析】
试题分析：盐的摄入对身体健康的有影响？科学家和一些专家就此进行了研究，发现这是耸人听闻的，人食用适量的盐是绝无影响的。
1.判断推理题。由文章第一段可知,医生反对食用盐，因为盐对健康有害，一些政治家也支持这个观点，美国国会议员尼尔史密斯说人体所消耗的盐的量和心脏病，循环障碍，中风甚至早逝有着直接的联系。因此选B。
2.判断推理题。由“Of the hypertensive patients, however, half of those on the low-salt diet did experience a drop in blood pressure, which returned to previous level when salt was reintroduced.”可知，然而有一半的高血压患者在食用了低盐食物后，血压有了下降的趋势，返回到了原先的水准。因此少量地消耗盐对于有些患者是有利的。故选A。
3.3】判断推理题。由第三段“So an opinion that the whole population should avoid salt makes no sense.”可知，让全人类对于盐避而远之是没啥意义的。故B符合题意。
4.4】细节理解题。根据文章最后一段，“Medical experts agree that everyone should practice reasonable “moderation” in salt consumption. For the average person, a moderate amount might run from four to ten grams a day, or roughly 1/2 to 1/3 teaspoons.”可知，正常人每天消耗4-10克食盐最佳，大约为1/2到1/3汤匙。故选C。
考点：社普类短文阅读。
