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The Vikings have left many traces of their settlement which are still visible today. Archaeology provides physical evidence of their conquests, settlement and daily life. The study of place names and language shows the lasting effect which the Viking settlements had in the British Isles, and DNA analysis provides some insights into the effect the Vikings had on the genetic stock of the countries where they settled. All of this provides valuable information, but the only reason that we have an idea of the "Vikings" as a people is their appearance in the written sources. Unfortunately, the value of the written evidence is limited. Not a lot of evidence survives, and much of what we have is either uninformative or unreliable. Many popular ideas about Vikings are nineteenth-century inventions. Others are the result of early historians accepting sources which modern scholars now regard as completely unreliable. In Scandinavia the Viking Age is regarded as part of prehistory because there are practically no contemporary written sources. Even in western Europe, the Viking Age is often seen as part of the "Dark Ages", from which comparatively few historical records have survived. Surviving accounts of Viking activity were almost exclusively written by clergymen (神职人员). These monastic chronicles (编年史) outline broadly what happened, at what date. There are also sources of a more directly religious nature, such as the much-quoted letters of Alcuin, and Wulfstan's famous "Sermon of the Wolf ", both of which chose to interpret the Viking raids as God's punishment on the Anglo-Saxons for their sins. Even the chronicles reflect the fact that the Vikings often attacked monasteries for their wealth, which created an obvious bias against them, and the hostile tone of these contemporary accounts has done much to create the popular image of Viking atrocities. However, modern historians have noted that the same sources show Christian rulers behaving equally unpleasantly, but without being condemned on religious grounds. We tend to think of the Vikings as a race of Scandinavian warriors, but the reality is more complex. Raids on the British Isles and the coasts of France and Spain were the work of Vikings from Norway and Denmark. The word Viking means one who lurks in a "vik" or bay, in effect, a pirate. The word "Viking" has come to describe a whole new age in Europe between about 800 and 1150. This is despite the fact that Vikings were not just pirates and warriors but also traders and colonists. But at the start of the Viking Age in the last decade of the 8th century, loot and adventure were the main goals of the Norwegians who raided in Scotland and Ireland and of the Danes who attacked England. Gold and silver treasures accumulated by the great monasteries could be converted into personal wealth and thus power, and captives could be sold as slaves. What better way for the young sons of good families to earn their way and see the world?

单选题 Gay Rights in Chile Every now and then a society is confronted by a crime so horrific that it prompts profound reflection and, eventually, change. Among such crimes was the murder in Chile of Daniel Zamudio. On October 28th 2012 a court sentenced one of his attackers to life in prison. Two of the others got 15 years each; the fourth got seven years. Zamudio was beaten unconscious in a park in the capital, Santiago, for being gay. His foul attackers carved swastikas (纳粹党所用的十字记号) into his skin, branded him with cigarettes and hit his right leg very hard with an 8 kg rock. According to the court testimony, they then urinated (小便) on his body. Zamudio died in hospital three weeks later. He was 24. The change that followed was brisk. Within weeks of the murder, legislators passed into law an anti-discrimination bill that had been kicking around Congress, largely ignored, for seven years. Gay rights have been a theme in the current presidential campaign. Most of the candidates say they now back gay marriage. Chile has never been an easy place for homosexuals (同性恋). The Catholic church maintains a frightening, if gradually decreasing, grip on public morality. Divorce was banned until 2004, and gay sex decriminalised only in 1999 (in Argentina and Brazil it has been legal since the 19th century). Chile is one of only four countries in South America where the age of consent is higher for gays than for heterosexuals (异性恋). And, depressingly, brutal attacks like the one on Zamudio continue. On October 20th 2012 a 21-year-old gay man, Wladimir Sepulveda, was assaulted in the town of San Francisco de Mostazal, 60kin south of Santiago, as he walked home with another man. His six attackers included two women. Witnesses said the attackers shouted homophobic (仇视同性恋的) insults at Mr. Sepulveda, shoved him to the ground and kicked and beat him unconscious. He remains in a coma (昏迷), fighting for his life—a sad reminder that Chile is not as safe and orderly a haven in an often violent continent as Chileans like to think. At least not for everyone.
