单选题Dear Sirs, Your shipment of twelve thousand 'Smart' watches was received by our company this morning. However, we wish to make a number of complaints concerning the serious delay in delivery and your failure to carry out our specific instructions with regard to this order. It was stressed from the beginning that the delivery date had to be less than six weeks from the initial order in order to meet our own customers' requirements. While we understand that delays in production are occasionally inevitable, we must point out that the major reason why the order was placed with your company was because we were assured by you of its speed of delivery, and that your existing stocks were sufficiently high to ensure immediate shipment. Late delivery of the goods has caused US to disappoint several of our most valued customers, and is bound to have a negative effect on potential future orders. The second complaint concerns the difference in color between the watches we ordered and those delivered. It was stated clearly in the original order that watches in combinations of green/purple and orange/purple only were required. However, only half the watches in the delivery received are of the colors specified. Our Hong Kong agent assures US that she stressed to you the importance of following our instructions precisely, since we consider there to be only a limited market in this country for watches of other colors at the present time. Any watches that are not of the specified colors will, of course, be returned to you. We are also somewhat concerned about the rather poor quality of the goods received, since it is apparent that the watches that finally arrived have been produced from inferior materials and have been manufactured to a lower standard than those in the sample. We have also found that a number of the watches do not appear to be functioning. Whether the latter problem is due to poor manufacture, damage during transportation or bad batteries is not yet clear, but we should like to point out that we feel this matter to be entirely your responsibility. As a result of the above problems, therefore, we feel that the most suitable course of action is to return to you unpaid any of the goods considered unsatisfactory, and to subtract any resultant costs from our final settlement. We shall also, of course, be forced to reconsider whether any further orders should be placed with your company. We look forward to your prompt reply. Yours sincerely, John Smith

单选题 Modern technology has put men on the moon and deciphered the human genome. But when it comes to brewing up flu to make vaccines, science still turns to the incredible edible egg. Ever since the 1940s, vaccine makers have grown large batches of virus inside chicken eggs. New cell-based technologies are in the pipeline, and may finally get the support they need now that the United States is faced with a critical shortage of flu vaccine. Although experts disagree on whether new ways of producing vaccine (疫苗) could have prevented a shortage like the one happening today, there is no doubt that the existing system has serious flaws. Each year, vaccine manufacturers place advance orders for millions of specially grown chicken eggs. Meanwhile, Public Health officials monitor circulating strains of flu, and each March they recommend three strains—two influenza A strains and one B strain—for manufacturers to include in vaccines. In the late spring and summer, automated machines inject virus into eggs and later suck out the influenza-rich goop. Virus from the eggs' innards gets killed and processed to remove egg proteins and other contaminants before being packaged into vials for fall shipment. Why has this egg method persisted for six decades? The main reason is that it's reliable. But even though the eggs are reliable, they have serious drawbacks. One is the long lead time needed to order the eggs. That means it's hard to make more vaccine in a hurry, in case of a shortage or unexpected outbreak. And eggs may simply be too cumbersome (大量的) to keep up with the hundreds of millions of doses required to handle the demand for flu vaccine. What's more, some flu strains don't grow well in eggs. Last year, scientists were unable to include the Fujian strain in the vaccine formulation. It was a relatively new strain, and manufacturers simply couldn't ind a quick way to adapt it so that it grew well in eggs. 'We knew the strain was out there,' recalls Theodore Eickhoff of the University of Colorado Health Sciences Center, 'but public-health officials were left without a vaccine—and, consequently, a more severe flu season.' Worse, the viruses that pose the greatest threat might be hardest to grow in eggs. That's because global pandemics like the one that killed over 50 million people between 1918 and 1920 are thought to occur when a bird influenza changes in a way that lets it cross the species barrier and infect humans. Since humans haven't encountered the new virus before, they have little protective immunity. The deadly bird flu circulating in Asia in 1997 and 1998, for example, worried Public Health officials because it spread to some people who handled birds and killed them—although the bug never circulated among humans. But when scientists tried to make vaccine the old-fashioned way, the bird flu quickly killed the eggs. (选自Time)

单选题Latino youths need better education for Arizona to take full advantage of the possibilities their exploding population offers. Arizona"s fast-growing Latino population offers the state tremendous promise and a challenge. Even more than the aging of the baby boomers, the Latino boom is fundamentally reorienting the state"s economic and social structure. Immigration and natural increase have added 600,000 young Latino residents to the state"s population in the past decade. Half of the population younger than 18 in both Phoenix and Tucson is now Latino. Within 20 years, Latinos will make up half of the homegrown entry-level labor pool in the state"s two largest labor markets. What is more, Hispanics are becoming key economic players. Most people don"t notice it, but Latinos born in Arizona make up much of their immigrant parents" economic and educational, deficits. For example, second-generation Mexican-Americans secure an average of 12 grades of schooling where their parents obtained less than nine. That means they erase 70 percent of their parents" lag behind third-generation non-Hispanic Whites in a single generation. All of this hands the state a golden opportunity. At a time when many states will struggle with labor shortages because of modest population growth, Arizona has a priceless chance to build a populous, hardworking and skilled workforce on which to base future prosperity. The problem is that Arizona and its Latino residents may not be able to seize this opportunity. Far too many of Arizona"s Latinos drop out of high school or fail to obtain the basic education needed for more advanced study. As a result, educational deficits are holding back many Latinos—and the state as well. To be sure, construction and low-end service jobs continue to absorb tens of thousands of Latino immigrants with little formal education. But over the long term, most of Arizona"s Latino citizens remain ill-prepared to prosper in an increasingly demanding knowledge economy. For the reason, the educational uplift of Arizona"s huge Latino population must move to the center of the state"s agenda. After all, the education deficits of Arizona"s Latino population will severely cramp the fortunes of hardworking people if they go unaddressed and could well undercut the state"s ability to compete in the new economy. At the entry level, slower growth rates may create more competition for low-skill jobs, displacing Latinos from a significant means of support. At the higher end, shortages of Latinos educationally ready to move up will make it much harder for knowledge-based companies staff to get high-skill positions.
