Increasingly, over the past ten years, people—especially young people—have become aware of the need to change their eating habits, because much of the food they eat, particularly foods, is not good for the health. Consequently, there has been a growing interest in natural foods: foods which do not contain chemical additives and which have not been affected by chemical fertilizers, widely used in farming to- day.
Natural foods, for example, vegetables, fruits and grains which have been grown in soil that is rich in organic matter. In simple terms, this means that the soil has been nourished by unused vegetable matter, which provides it with essential vitamins and minerals. This in itself is a natural process compared with the use of chemicals and fertilizers, the main purpose of which is to increase the amount—but not the quality—of foods grown in commercial farming areas.
Natural foods also include animals which have been allowed to feed and move freely in healthy pastures. Compare this with what happens in the mass production of poultry: there are battery farms, for ex- ample, where thousands of chickens live crowded together in one building and are fed on food which is little better than rubbish. Chickens kept in this way are not only tasteless as food; they also produce eggs which lack important vitamins.
There are other aspects of healthy eating which are now receiving increasing attention from experts on diet. Take, for example, the question of sugar, this is actually a non-essential food! Although a natural alternative, such as honey, can be used to sweeten food if this is necessary, we can in fact do without it. It is not that sugar is harmful in itself. But it does seem to be an additive: the quantity we use has grown steadily over the last two centuries and in Britain today each person consumes an average of 200 pounds a year! Yet all it does is provide us with energy, in the form. of calories. There are no vitamins in it, no minerals and no fibre.
It is significant that nowadays fibre is considered to be an important part of a healthy diet. In white bread, for example, the fibre has been removed. But it is present in unrefined flour and of course in vegetable. It is interesting to note that in countries where the national diet contains large quantities of unrefined flour and vegetable, certain diseases are comparatively rare. Hence the emphasis placed on the eating of wholemeal bread and more vegetables by modern experts on healthy eating.
Recently, some people are interested in natural foods because ______.
A．these foods are fresh and sweet
B．they want to change their eating habits
C．these foods do not contain chemical additives and have not been affected by chemical fertilizers
D．they don't like the processed foods

In any country the wages commanded by laborers who have comparable skills but who work in various industries are determined by the productivity of the least productive unit of labor, i.e., that unit of labor which works in the industry which has the greatest economic disadvantage. We will represent the various opportunities of employment in a country like the United States by symbols: A, standing for a group of industries in which we have exceptional, economic advantages over foreign countries; B, for a group in which our advantages are less; C, one in which they are still less; D, the group of industries in which they are least of all.
When our population is so small that all our labor can be engaged in the group represented by A, productivity of labor (and therefore wages) will be at their maximum. When our population increases so that some of the labor will have to be set to work in group B, the wages of all labor must decline to the level of the productivity in that group. But no employer, without government aid, will yet be able to afford to hire labor to exploit the opportunities represented by C and D, unless there is a further increase in population.
But suppose that the political party in power holds the belief that we should produce every thing that we consume, that the opportunities represented by C and D should be exploited. The commodities that the industries composing C and D will produce have been hitherto obtained from abroad in exchange for commodities produced by A and B. The government now renders this difficulty by placing high duties upon the former class of commodities. This meads that workers in A and B must pay higher prices for what they buy, but do not receive higher prices for what they sell.
After the duty has gone into effect and the prices of commodities that can be produced by C and D have risen sufficiently, enterprisers will be able to hire labor at the wages prevailing in A and B, and establish industries in C and D. So far as the remaining laborers in A and B buy the products of C and D, the difference between the price which they pay for those products and the price that they would pay if they were permitted to import those products duty-free is a tax paid not to the government, but to the producers in C and D, to enable the latter to remain in business. It is an uncompensated deduction from the natural earnings of the laborers in A and B. Nor are the workers in C and D paid as much, estimated in purchasing power, as they would have received if they had been allowed to remain in A and B under the earlier conditions.
When C and D are established, workers in these industries______.
A．receive higher wages than do the workers in A and B
B．receive lower wages than do the workers in A and B
C．are not affected so adversely by the levying of duties as are workers in A and B
D．receive wages equal to those workers in A and B

Jobs genius for creating products and his marketing talent have long been hailed. All of that comes through in Becoming Steve Jobs, Schlender s and Tetzeli s new book. They contend that Jobs was a far more complex and interesting man than the half-genius / half-jerk stereotype, and a good part of their book is an attempt to craft a more rounded portrait. What makes their book important is that they also contend—persuasively, I believe—that, the stereotype notwithstanding, he was not the same man in his prime that he had been at the beginning of his career. The inexperienced, impulsive, arrogant youth who co-founded Apple was very different from the mature and thoughtful man who returned to his struggling creation and turned it into a company that made breathtaking products while becoming the dominant technology company of our time. Had he not changed, they write, he would not have succeeded.

Many people with ordinary jobs may dream of long holidays in foreign countries, but they know they couldn’t afford them even if they could get enough time off from the company.However, there are a few businesses which have started schemes to reward employees with long service by giving them a chance to fulfill such ambitions by providing both the time and the money.
One company gives every employee over 50 years old and who has been with them for 25 years, six months’ holiday on full pay.At the same time additional money can be made available by way of loans, to help them with projects they cannot otherwise offer.Most of the people who have already benefited from the scheme, have used the opportunity to travel to distant places like the Far East or South America and some have spent the money on their favorite hobbies, such as photography.
The cost of providing these special holidays is fairly high but the directors feel it is well worthwhile because the employees are greatly refreshed by their long break from the pressures and routines of their jobs.The only problems are that the people concerned tend to have key jobs which can be difficult to fill on a temporary basis for a relatively long time.Besides, some employees find it difficult to re-adjust to the old routine after such a long time away.In addition, one or two people may not feel secure at leaving their job in someone else’s hands.On balance, however, there is no doubt that the idea is beneficial to industrial relations and a wonderful reward for long service.
