单选题Poseidon sat at his desk, doing figures. The administration of all the waters gave him endless work. He could have had assistants, as many--and he did have very many--but since he took his job very seriously, he would in the end go over all the figures and calculations himself, and thus his assistants were of little help to him. It cannot be said that he enjoyed his work: he did it only because it had been assigned to him; in fact, he had already filed many petitions foras he put it--more cheerful work, but every time the offer of something different was made to him it would turn out that nothing suited him quite as well as his present position. And anyhow it was quite difficult to find something different for him. After all, it was impossible to assign him to a particular sea; aside from the fact that even then the work with figures would not become less but only pettier, the great Poseidon could in any case occupy only an executive position. And when a job away from the water was offered to him he would get sick at the very prospect, his divine breathing would become troubled and his brazen chest began to tremble. Besides, his complaints were not really taken seriously; when one of the mighty is vexatious the appearance of an effort must be made to placate him, even when the case is most hopeless. In actuality a shift of posts was unthinkable for Poseidon--he had been appointed God of the Sea in the beginning, and that he had to remain. What irritated him most-- and it was this that was chiefly responsible for his dissatisfaction with his job--was to hear of the conceptions formed about him: how he was always riding about through the tides with his trident. When all the while he sat here in the depths of the world--ocean, doing figures uninterruptedly, with now and then a trip to Jupiter as the only break in the monotony--a trip, moreover, from which he usually returned in a rage. Thus he had hardly seen the sea--had seen it but quickly in the course of hurried trips to Olympus, and he had never actually traveled around it. He was in the habit of saying that what he was waiting for was the fall of the world; then, probably, a quiet moment would be granted in which, just before the end and having checked the last row of figures, he would be able to make a quick little tour. Poseidon became bored with the sea. He let fall his trident. Silently he sat on the rocky coast and a gull, dazed by his presence, described wavering circles around his head.

单选题Children are getting so fat they may be the first generation to die before their parents, an expert claimed yesterday. Today"s youngsters are already falling prey to potential killers such as diabetes because of their weight. Fatty fast-food diets combined with sedentary lifestyles dominated by televisions and computers could mean kids will die tragically young, says Professor Andrew Prentice, from the London School of Hygiene and Tropical Medicine. At the same time, the shape of the human body is going through a huge evolutionary shift because adults are getting so fat. Here in Britain, latest research shows that the average waist size for a man is 36-38in and may be 42-44in by 2032. This compares with only 32.6 in in 1972. Women"s waists have grown from an average of 22 inches in 1920 to 24 inches in the Fifties and 30 inches now. One of the major reasons why children now are at greater risk is that we are getting fatter younger. In the UK alone, more than one million under-16s are classed as overweight or obese — double the number in the mid-Eighties. One in ten four-year-olds are also medically classified as obese. The obesity pandemic—an extensive epidemic—which started in the US, has now spread to Europe, Australia, Central America and the Middle East. Many nations now record more than 20 per cent of their population as clinically obese and well over half the population as overweight. Prof Prentice said the change in our shape has been caused by a glut of easily available high-energy foods combined with a dramatic drop in the energy we use as a result of technology developments. He is not alone in his concern. Only last week one medical journal revealed how obesity was fuelling a rise in cancer cases. Obesity also increases the risk factor for strokes and heart disease. An averagely obese person"s lifespan is shortened by around nine years while a severely obese person by many more. Prof Prentice said: "So will parents outlive their children, as claimed recently by an American obesity specialist?" The answer is yes—and no. Yes, when the offspring become grossly obese. This is now becoming an alarmingly common occurrence in the US. Such children and adolescents have a greatly reduced quality of life in terms of both their physical and psychosocial health. So say No to that doughnut and burger.
