Text 1

In recent years, there has been a steady assault on salt from the doctors: salt is bad for you ? regardless of your health. Politicians also got on board. "There is a direct relationship," US congressman¹ Neal Smith noted², "between the amount of sodium³ a person consumes and heart disease, circulatory disorders⁴, 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 this hue⁵ and cry about eating salt is unnecessary," Dr. Dustan insists. "For most of us it probably doesn't 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 subjects, however, half of those on the low-salt diet did experience a drop in blood pressure, which returned to its previous level when salt was reintroduced."An adequate to somewhat excessive salt intake⁶ has probably saved many more lives than it has cost in the general population," notes Dr. John H. Laragh. "So a recommendation that the whole population should avoid salt makes no sense."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 of a teaspoon⁷. The equivalent of one to two grams of this salt allowance would come from the natural sodium in food. The rest would be added in processing, preparation or at the table.Those with kidney, liver or heart problems may have to limit dietary salt, if their doctor advises. But even the very vocal⁸ "low salt" exponent⁹, Dr. Arthur Hull¹⁰ Hayes, Jr. admits that "we do not know whether increased sodium consumption causes hypertension." In fact, there is growing scientific evidence that other factors may be involved: deficiencies in calcium¹¹, potassium, perhaps magnesium¹²; obesity¹³ (much more dangerous than sodium); genetic¹⁴ predisposition; stress."It is not your enemy," says Dr. Laragh. "Salt is the No. 1 natural component¹⁵ of all human tissue, and the idea that you don't 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. According to some doctors and politicians, the amount of salt consumed[A] exhibits as an aggravating¹⁶ factor to people in poor health.[B] cures diseases such as stroke and circulatory disorders.[C] correlates highly with some diseases.[D] is irrelevant¹⁷ to people suffering from heart disease.

2. From Dr. Dustan's study we can infer that[A] a low-salt diet may be prescribed for some people.[B] the amount of salt intake has nothing to do with one's blood pressure.[C] the reduction of salt intake can cure a hypertensive patient.[D] an extremely low-salt diet makes no difference to anyone.

3. In the third paragraph, Dr. Laragh implies that[A] people should not be afraid of taking excessive salt.[B] doctors should not advise people to avoid salt.[C] an adequate to excessive salt intake is recommended for people in disease.[D] excessive salt intake has claimed some victims in the general population.

4. The phrase "vocal ... exponent" (line 2, para. 4) most probably refers to[A] eloquent¹⁸ doctor.[B] articulate opponent.[C] loud speaker.[D] strong advocate.

5. What is the main message of this text?[A] That the salt scare is not justified¹⁹.[B] That the cause of hypertension is now understood.[C] That the moderate use of salt is recommended.[D] That salt consumption is to be promoted.

From her vantage point she watched the main doors swing open and the first arrivals pour in. Those who had been at the head of the line paused momentarily on entry, looked around curiously²¹, then quickly moved forward as others behind pressed in. Within moments the central public area of the big branch bank was filled with a chattering²², noisy crowd. The building, relatively²³ quiet less than a minute earlier, had become a Babel. Edwina saw a tall heavyset black man wave some dollar bills and declare loudly, "I want to put my money in the bank"

It seemed as if the report about everyone having come to open an account had been accurate after all.

Edwina could see the big man leaning back expansively, still holding his dollar bills. His voice cut across the noise of other conversations and she heard him proclaim, "I'm in no hurry. There's something I'd like you to explain."Two other desks were quickly manned by other clerks. With equal speed, long wide lines of people formed in front of them.Normally, three members of staff were ample to handle new account business, but obviously were inadequate²⁴ now. Edwina could see Tottenhoe on the far side of the bank and called him on the intercom. She instructed, "Use more desks for new accounts and take all the staff you can spare to man them."

Tottenhoe grumbled²⁵ in reply, "You realize we can't possibly process all these people today, and however many we do will tie us up completely.""I've an idea," Edwina said, "that's what someone has in mind. Just hurry the processing all you can."

First, an application form called for details of residence, employment, social security, and family matters. A specimen²⁶ signature was obtained. Then proof of identity was needed. After that, the new accounts clerk would take all documents to an officer of the bank for approval and initialing. Finally, a savings²⁷ passbook²⁸ was made out or a temporary checkbook issued.Therefore the most new accounts that any bank employee could open in an hour were five, so the three clerks presently working might handle a total of ninety in one business day, if they kept going at top speed, which was unlikely.

Still the noise within the bank increased. It had become an uproar²⁹.

A further problem was that the growing mass of arrivals in the central public area of the bank was preventing access to tellers³⁰' counters by other customers. Edwina could see a few of them outside, regarding the milling scene with consternation³¹. While she watched, several gave up and walked away.Inside the bank some of the newcomers were engaging tellers in conversation and the tellers, having nothing else to do because of the melee³², chatted back. Two assistant managers had gone to the central floor area and were trying to regulate the flood of people so as to clear some space at counters. They were having small success.

She decided³³ it was time for her own intervention³⁴.
