• The growth of the use of English as the world`s primary language for international communication has obviously been continuing for several decades.

  (46)But even as the number of English speakers expands further there are signs that the global predominance of the language may fade within the foreseeable future. Complex international, economic, technological and culture change could start to diminish the leading position of English as the language of the world market, and UK interests which enjoy advantage from the breath of English usage would consequently face new pressures. Those realistic possibilities are highlighted in the study presented by David Graddol (47)His analysis should therefore end any self-contentedness among those who may believe that the global position of English is so stable that the young generation of the United Kingdom do not need additional language capabilities. David Graddol concludes that monoglot English graduates face a bleak economic future as qualified multilingual youngsters from other countries are proving to have a competitive advantage over their British counterparts in global companies and organizations. Alongside that,(48)many countries are introducing English into the primary-school curriculum but British schoolchildren and students do not appear to be gaining greater encouragement to achieve fluency in other languages. If left to themselves, such trends will diminish the relative strength of the English language in international education markets as the demand for educational resources in languages, such as Spanish ,Arabic or Mandarin grows and international business process outsourcing in other language such as Japanese, French and German, spreads. (49)The changes identified by David Graddol all present clear and major challenges to UK`s providers of English language teaching to people of other countries and to broader education business sectors. The English language teaching sector directly earns nearly &1.3 billion for the UK in invisible exports and our other education related explores earn up to &10 billion a year more. As the international education market expands, the recent slowdown in the number of international students studying in the main English-speaking countries is likely to continue, especially if there are no effective strategic policies to prevent such slippage. The anticipation of possible shifts in demand provided by this study is significant:(50) It gives a basis to all organization which seek to promote the learning and very different operating environment. That is a necessary and practical approach. In this as in much else, those who wish to influence the future must prepare for it. 请帮忙给出每个问题的正确答案和分析，谢谢！

• An army scientist has helped solve the decades-old murder mystery surrounding the last Russian czar.

  The bones unearthed in a shallow grave definitely are those of Czar Nicholas II, said Lt. Col (Dr.) Victor Weedn at an Aug. 31 news conference. Weedn heads the Armed Forces DNA Identification Laboratory in Rockville, Md., which is involved in identifying skeletal remains of U. S. service members who served in Vietnam, Korea and World War II. The attempt to identify the czar presented a special challenge. The armed forces lab was the perfect place to perform. the type of genetic testing on old, deteriorating bones that was needed in this case, he said. Until the announcement, scientists had not been able to say for sure whether the bones were those of the czar. Russian DNA expert Pavel Ivanov, who with Weedn oversaw a team of U. S. military civilians tasked to identify the remains, reached the same conclusion. Nicholas and his family were rounded up by the Bolsheviks and executed by firing squad in 1918. Their bodies were dumped into a pool of sulfuric acid 20 miles outside the Ural Mountain city of Yekaterinburg. The shallow grave was uncovered in 1979. Bone fragments believed to be those of the czar, the Czarina Alexandra and three of their five children were unearthed in 1991. While investigators were able to positively identify the czarina and the daughters early on, a rare, benign genetic condition that first showed up in his generation did not allow them to make a positive identification of Nicholas II. Rare mutation the key In the end, it was that genetic mutation which provided the key to solving the mystery, Weedn said. Nicholas' brother, whose remains were exhumed in July 1994, turned out to have the same mutation in his genetic makeup. It is so rare that it makes the identification absolute, he said. If Russian authorities accept that finding, it will clear the way for the ceremonial burial of the last emperor of Russia. But the new evidence did not satisfy all skeptics. Emigre Eugene Magerovsky, a retired Russian military intelligence officer, interrupted the news conference to say he was suspicious of how the bones "suddenly" came to light during the Soviet era. "The Soviets have always been masters of all kinds of shenanigans," he said. He suggested the investigators may have been given two bones from the same corpse, in which case the DNA would have had to match. Weedn ruled that out, as the tibia and femur from the same side of each body were used in the testing. Ivanov, a forensic science professor in charge of identifying the remains of the last czar and his family, brought the femur bones—as well as a blood sample from a living relative— to the Rockville laboratory in June. Much evidence lost Years of exposure to minerals in the soil destroyed much of the genetic evidence in the bone, Weedn said. Still, through a painstaking process of grinding up bone, reproducing the genetic material from the dust and comparing the results over and over again, the team was able to reach its conclusion. One mystery Weedn and Ivanov did not address was that of the czar's daughter, Anastasia. Whether she somehow escaped the Bolsheviks' bullets has been the topic of intense debate for more than half a century. The grave yielded bones from only three of the five daughters. Still unresolved is whether Anastasia or Marie might have survived, along with the sickly heir, Alexis. Weedn, whose laboratory has tested two women who claimed to be Anastasia, found they were not. A third who sought testing has not sent in blood samples for testing, he added. On-again, off-again pairing Weedn was approached by Ivanov four years ago about becomi
