单选题The men set off in silence. Pedro walked with his dog a few paces behind the boys. When neighbors saw them walking along in this formation they would say that Pedro looked like a veritable patron striding behind his peons. Yet there were mornings when Pedro talked to the boys in the course of their two-hour walk to the fields, giving advice or telling what work had to be done. The boys, however, spoke only in answer to a question. Out of their father" s earshot they would joke about their sweethearts or visits to the saloons of Cuahnahuac. But this morning they moved silently down the road. It was still barely light. All around them, just beyond the far edges of the fields, the blue-green slopes of the pine-covered mountains rose through the morning mist. Pedro and Ricardo were headed for the mountain slope cornfield which they had cleared the year before. This was communal land belonging to the municipality which consisted of seven villages; anyone could work it. New clearings had to be made every two or three years, for heavy rains washed the topsoil away. To acquire new fields Pedro and his sons burned the brush and weeds, cut down young trees, and built new stone fences. The boys worked well; they had the largest mountain clearing in Azteca. But the crops could supply enough corn and beans for only three or four months. So Pedro had to try other means of earning a living as well — making rope from maguey fiber, selling plums, hiring out his sons as farm hands. One thing he would not do to earn money was to make charcoal for sale, as so many of his neighbors did. This practice, he knew, was wasteful of the precious oak and pine forests and ultimately ruined land. He had been one of the leaders in the struggle for the preservation of the communal forest lands. So he made charcoal only once a year and only for the use of his family.

单选题In the early 1960s Wilt Chamberlain was one of only three players in the National Basketball Association (NBA) listed at over seven feet. If he had played last season, however, he would have been one of 42. The bodies playing major professional sports have changed dramatically over the years, and managers have been more than willing to adjust team uniforms to fit the growing numbers of bigger, longer frames. The trend in sports, though, may be obscuring an unrecognized reality: Americans have generally stopped growing. Though typically about two inches taller now than 140 years ago, today"s people—especially those born to families who have lived in the U.S. for many generations—apparently reached their limit in the early 1960s. And they aren"t likely to get any taller. "In the general population today, at this genetic, environmental level, we"ve pretty much gone as far as we can go," says anthropologist William Cameron Chumlea of Wright State University. In the case of NBA players, their increase in height appears to result from the increasingly common practice of recruiting players from all over the world. Growth, which rarely continues beyond the age of 20, demands calories and nutrients—notably, protein—to feed expanding tissues. At the start of the 20th century, under-nutrition and childhood infections got in the way. But as diet and health improved, children and adolescents have, on average, increased in height by about an inch and a half every 20 years, a pattern known as the secular trend in height. Yet according to the Centers for Disease Control and Prevention, average height—5"9" for men, 5"4" for women—hasn"t really changed since 1960. Genetically speaking, there are advantages to avoiding substantial height. During childbirth, larger babies have more difficulty passing through the birth canal. Moreover, even though humans have been upright for millions of years, our feet and back continue to struggle with bipedal posture and cannot easily withstand repeated strain imposed by oversize limbs. "There are some real constraints that are set by the genetic architecture of the individual organism," says anthropologist William Leonard of Northwestern University. Genetic maximums can change, but don"t expect this to happen soon. Claire C. Gordon, senior anthropologist at the Army Research Center in Natick, Mass, ensures that 90 percent of the uniforms and workstations fit recruits without alteration. She says that, unlike those for basketball, the length of military uniforms has not changed for some time. And if you need to predict human height in the near future to design a piece of equipment, Gordon says that by and large, "you could use today"s data and feel fairly confident."

单选题Could the bad old days of economic decline be about to return? Since OPEC agreed to supply-cuts in March, the price of crude oil has jumped to almost $26 a barrel, up from less than $10 last December. Tbis near-tripling of oil prices calls up scary memories of the 1973 oil shock, when prices quadrupled, and 1979-1980, when they also almost tripled. Both previous shocks resulted in double-digit inflation and global economic decline. So where are the headlines warning of gloom and doom this time? The oil price was given another push up this week when Iraq suspended oil exports. Strengthening economic growth, at the same time as winter grips the northern hemisphere, could push the price higher still in the short term. Yet there are good reasons to expect the economic consequences now to be less severe than in the 1970s. In most countries the cost of crude oil now accounts for a smaller share of the price of petrol than it did in the 1970s. In Europe, taxes account for up to four-fifths of the retail price, so even quite big changes in the price of crude have a more muted effect on pump prices than in the past. Rich economies are also less dependent on oil than they were, and so less sensitive to swings in the oil price. Energy conservation, a shift to other fuels and a decline in the importance of heavy, energy-intensive industries have reduced oil consumption. Software, consultancy and mobile telephones use far less oil than steel or car production. For each dollar of GDP ( in constant prices) rich economies now use nearly 50% less oil than in 1973. The OECD estimates in its latest Economic Outlook that, if oil prices averaged $22 a barrel for a full year, compared with $13 in 1998, this would increase the oil import bill in rich economies by only 0.25% ~ 0.5% of GDP. That is less than one-quarter of the income loss in 1974 or 1980. On the other hand, oil-importing emerging economies—to which heavy industry has shifted—have become more energy-intensive, and so could be more seriously squeezed. One more reason not to lose sleep over the rise in oil prices is that, unlike the rises in the 1970s, it has not occurred against the background of general commodity-price inflation and global excess demand. A sizable port/on of the world is only just emerging from economic decline. The Economist's commodity price index is broadly unchanging from a year ago. In 1973 commodity prices jumped by 70% , and in 1979 by almost 30%.
