[单项选择]The history of the computer in the twentieth century is one of dramatic adaptation and expansion. The computer had modest beginnings in areas where it was used as a specialist tool. The first electronic computer was built in the 1930s and was solely for the use of undergraduate students in Iowa State University to handle mathematical computations in nuclear physics. In the 1960s an early version of the Internet, ARPPANET was used in computer science and engineering projects. However, only 10 years later computers were starting to change our life style, the way we do business and many other things and by the late 1980s’ networks were expanding to embrace sections of the general public.

[单项选择] To fight against computer crimes, a computer system needs a sure way of identifying its right users and rejecting those who are not entitled to use it. The identification system should be quick, simple, and convenient.
At present, signatures are widely used to identify credit card holders, but it takes an expert to detect a good forgery. Sometimes even a human expert is fooled, and there is no reason to believe that a computer could do any better.
Photographs are also sometimes used for identification. But, people find it inconvenient to stop by a credit-card company and to be photographed. Companies might lose business if they made the pictures under absolute requirement. Also, photographs are less useful these days, when people frequently change their appearance by changing the way they wear their hair. Finally, computer programs for analyzing photographs are still highly experimental.
Cash-drawing systems often use two identification numbers: One is recorded on a
A. Convenience.
B. Reliability.
C. Low costs.
D. Acceptability.

[单项选择]When Rupert Murdoch sees beams of light in the American advertising market, it is not necessarily time to reach for the sunglasses. Last October, when the impact of September 11th was only beginning to tell, the boss of NASCAR, a media group, had already identified " strong rays of sunshine". With ad sales still languishing, Mr. Murdoch declared last month that " there are some hints of a modest upswing in tile US advertising market". His early optimism turned out to be misplaced. Now, however, other industry observers are beginning to agree with him.Signs of improvement are visible in the advertising of______.
[A] high-tech magazines and sports industry
[B] celebrity magazines and travel industry
[C] women’s magazines and car industry
[D] movie industry and high-teeh magazines
A. Advertising usually exaggerates the economic cycle, falling sharply and early in a downturn, and rebounding strongly once the economy has begun to recover. This is because most managers prefer to trim their ad budgets rather than their payrolls, and restore such spending only once they feel sure that things are looking up. Last year, America’s ad market shrank by 9. 8% , according to CMIR, a research firm. Although ad spending has not yet recovered across all media, some analysts now expect overall ad spending to start to grow in the third quarter.
B. The signs of improvement are patchy, however. Ad spending on radio and television seems to be inching up—advertising on American National Radio was up 2% in January on the same period last year, according to Aegis—while spending on magazines and newspapers is still weak. Even within any one market, there are huge differences; just pick up a copy of one of the now-slimline high-teeh magazines that once bulged with ads, and compare it with the hefty celebrity or women’s titles. Advertisers in some categories, such as the travel industry, are still reluctant to buy space or airtime, while others, such as the car and movie businesses, have been bolder. The winter Olympics, held last month in Salt Lake City, has also distorted the spending on broadcast advertising in the first quarter.
C. Nonetheless, there is an underlying pattern. One measure is the booking of ad spots for national brands on local television. By early March, according to Mr. Westerfield’s analysis, such bookings were growing fast across eight out of the top ten advertising sectors, led by the financial and motor industries. UBS Warburg now expects the " upfront" market, which starts in May when advertisers book advance ad spots on the TV networks for the new season in September, to be up 4% on last year. On some estimates, even online advertising could pick up by the end of the year.
