22、vation is now occurring in all scientific and technological fields. This wave of unprecedented change is driven primarily by advances in information technology, but it is much larger in scope. We are not dealing simply with an Information Revolution but with a Technology Revolution.To anticipate dev
23、elopments in this field, the George Washington University Forecast of Emerging Technologies was launched at the start of the 1990s. We have now completed four rounds of our Delphi survey in 1990, 1992, 1994, and 1996 giving us a wealth of data and experience. We now can offer a reasonably clear pict
24、ure of what can be expected to happen in technology over the next three decades.Time horizons play a crucial role in forecasting technology. Forecasts of the next five to ten years are often so predictable that they fall into the realm of market research, while those more than 30 or 40 years away ar
25、e mostly speculation. This leaves a 10- to 20-year window in which to make useful forecasts. It is this time frame that our Forecast addresses.The Forecast uses diverse methods, including environmental scanning, trend analysis, Delphi surveys, and model building. Environmental scanning is used to id
26、entify emerging technologies. Trend analysis guides the selection of the most important technologies for further study, and a modified Delphi survey is used to obtain forecasts. Instead of using the traditional Delphi method of providing respondents with immediate feed- back and requesting additiona
27、l estimates in order to arrive at a consensus, we conduct another survey after an additional time period of about two years.Finally, the results are portrayed in time periods to build models of unfolding technological change. By using multiple methods instead of relying on a single approach, the For
28、ecast can produce more reliable, useful estimates.For our latest survey conducted in 1996, we selected 85 emerging technologies representing the most crucial advances that can be foreseen. We then submitted the list of technologies to our panel of futurists for their judgments as to when (or if) eac
29、h technological development would enter the mainstream, the probability that it would happen, and the estimated size of the economic market for it. In short, we sought a forecast as to when each emerging technology will have actually “emerged“.（分数：5.00）(1).What we are faced with at present can be be

33、B.C.D.九、BPassage 2/B(总题数：1，分数：5.00)Your passport is your official identification as an American citizen. In America, most people never consider obtaining a passport unless they are planning a trip out of the country. In Europe, where travel from one country to another is much more common, almost eve
34、ryone carries a passport. A passport is final proof of identity in almost every country in the world.In 1979 almost 15 million Americans held passports. Most of these passports were obtained to travel outside the country because, except for a few Western nations, passports are required to enter ever
35、y country. And if you travel abroad, you must have a valid passport to reenter the country.When traveling abroad, you will need a passport for identification when ex- changing dollars for francs or marks or other foreign currency. You may also need your passport to use a credit card, buy an airplane
36、 ticket, check into a hotel or casino. As a passport is as official U. S. document, it is valuable as identification in any emergency overseas, such as floods, fires, or war.Dont confuse passports and visas. Whereas a passport is issued by a country to its citizens, a visa is official permission to
37、visit a country granted by the government of that country. For some years, many countries were dropping their visa requirements, but that trend has reversed. Argentina, Brazil, and Venezuela now require visas from U.S. citizens. They may be obtained from the embassy of the country you wish to visit.
38、Passport applications are avaliable at passport agency offices in large cities like Boston, New York, or Chicago. In smaller cities, applications are available at post offices and at federal courts. To get your first passport, you must submit the application in person, along with a birth certificate
39、 and two pictures.Maybe because most Americans use their passports only when traveling and because they are good for five years, many people lose their passports. Last year, more than 25,000 passports were stolen. And every passport is worth thousands of dollars to smugglers or criminals who desire
40、to enter this country illegally or assume a false identity. Travelers should keep their passports in their pockets or pocket- books at all times; never pack them or leave them in a room or automobile; when you arrive back home, store your passport in a safe or safety deposit box. And report a lost o
41、r stolen passport immediately; it is literally your identity.（分数：5.00）(1).The main purpose of this passage is to _.

42、).Passports are beneficial for _. A. exchanging currency B. using a credit card C. checking into hotels D. all of the above（分数：1.00）A.B.C.D.(3).We can conclude from the passage that _. A. visas are required to obtain passports B. foreign governments issue visas instead of passports C. visas and pass
43、ports are the same thing D. passports are more important than visas（分数：1.00）A.B.C.D.(4).The passage suggests that _. A. passports are obtained at the embassy once you enter a country B. passports are simple to obtain through the mail C. passports arent important once you are in the country youve cho

45、tates has focused on two factors: social standing and the loss of national culture. In general, excessive stress is placed on one factor or the other, depending on whether the commentator is North American or Puerto Rican. Many North American social scientists, such as Oscar Handlin, Joseph Fitzpatr
46、ick, and Oscar Lewis, consider Puerto Ricans as the most recent in a long line of ethnic entrants to occupy the lowest rung on the social ladder. Such a “sociodemographic“ approach tends to regard assimilation as a benign process, taking for granted increased economic advantage and inevitable cultural-integration, in a supposedly egalitarian context. However, this approach fails to take into account the colonial nature of the Puerto Rican case, with this group, unlike their European predecessors, coming from a nation politically subor
