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 congressman Neal Smith noted, "between the amount of sodium a person consumes and heart disease, circulatory 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 this hue 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 intake 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 teaspoon. The equivalent of one to two grams of this sat 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 vocal "low salt" exponent, Dr Arthur Hull 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 calcium, potassium, perhaps magnesium; obesity (much more dangerous than sodium); genetic predisposition; stress.

"It is not your enemy," says Dr Laragh. "Salt is the No. 1 natural component 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."

According to some doctors and politicians, the amount of salt consumed______.

A．exhibits as an aggravating factor to people in poor health

B．cures diseases such as stroke and circulatory disorders

C．correlates highly with some diseases

D．is irrelevant to people suffering from heart disease

A steady decline in annual movie-ticket sales is about to begin. More than half of the tickets sold last year were sold to the age group under twenty-five years of age, representing twenty-seven percent of the population.

Which of the following, if true, casts most doubt on the prediction above regarding future movie-ticket sales?

A.Medical advances have lowered the mortality rates for those who are forty to sixty years of age.

B.Many people gradually lose interest in going to the movies after they reach twenty-five years of age.

C.The number of movie theaters has been increasing, and this trend is expected to continue during the next ten years.

D.Movie-ticket sales tend to increase as the size of the work force increases, and the size of the work force will increase annually during the next decade.

E.Experts agree that people under twenty-five years of age will continue to account for more than half of the total number of tickets sold in each of the next ten years.

第10题

Any lender about to make a loan wishes to know the real rate of interest; i. e. , the contractual rate of interest less the rate of inflation. But what rate of inflation to use, past or expected? Past inflation is the better choice, because we have specific firm figures for it so that the real rate of interest will also emerge as a specific figure. Which of the following, if true, is the strongest point that an opponent of the position above might make in arguing that the rate of expected inflation is the proper figure to use?

A．Since the contractual interest is future income to a prospective lender, it is more appropriate to adjust that income in terms of inflation expected for the future.

B．Since estimating the rate of expected inflation presupposes careful economic analysis, lenders might derive coincidental benefits from doing such an estimate.

C．The rate of expected inflation will differ little from the rate of past inflation when inflation is steady.

D．No official rate of past inflation is computed for any period shorter than a month.

E．The official rate of past inflation is a figure that depends on what commodities, in what proportions, determine the official price index.
