The government’s new cyber-security
officials yesterday asked telecommunications companies for help in building at
government computer network that would have "no risk of outside penetration" — a
task some computer security consultants say is nearly impossible. Plans for the
private network, called Govnet, hinge on whether a reliable network
infrastructure can be built at an affordable price, officials said. Computer
system consultants said they could not estimate how much the network would cost
because of the government’s enormous size and security needs. Richard Clarke,
who was appointed special adviser to the president for cyberspace security this
week, said he believes a more reliable system can be built. Ninety percent of
available fiber-optic space is unused and fairly inexpensive to obtain, he
said. Govnet is part of a A. it will entail considerable cost. B. there isn’t a reliable network infrastructure yet. C. it will be difficult for Govnet to fit into the Internet. D. no telecommunications company can afford it.

[单项选择] {{B}}TEXT D{{/B}} The government’s economic
report came out the other day, and it shows the Gross Domestic Product--the
GDP--was up more than 7.2 percent.., the highest one-quarter jump in 20 years.
But the GDP is a measure of what HAS happened. The question is: what about the
future Well, the same day the GDP report came out, the Atlanta Business
Chronicle was reporting increased profits from several of Atlanta’s largest
corporations: BellSouth, Southern Company, Georgia Pacific, Equifax, Agco. UPS
(United Parcel Service) showed a 28 percent increase, and that one is especially
important because shipping companies are generally recognized as early
indicators of things to come in the business world. And, sure enough, the

[单项选择] {{B}}TEXT C{{/B}} The idea that government
should regulate intellectual property through copyrights and patents is
relatively recent in human history, and the precise details of what intellectual
property is protected for how long vary across nations and occasionally change.
There are two standard sociological justifications for patents or copyrights:
They reward creators for their labor, and they encourage greater creativity.
Both of these are empirical claims that can be tested scientifically and could
be false in some realms. Consider music. Star performers existed
before the 20th century, such as Franz Liszt and Niccolo Paganini, but mass

distribution companies and for a few celebrities, thereby helping to support the

demonstrate valid new uses for drugs already on the market. Also, there arc
numerous examples of medical progress resulting from the serendipitous
observations and therapeutic
