A recent development is the local area network (LAN).【21】its name implies, it serves a local area-possibly as small as a single room, typically an area like an university campus or the premises of a particular business. Local area networks were developed to【22】a need specific to microcomputers the sharing of expensive resources. Microcomputers are cheap, but highcapacity disc stores, fast and/or good quality printers, etc. are expensive. The object of the LAN is to allow【23】microcomputers shared access to these expensive resources, since the microcomputers are cheap, it is a necessary feature of a LAN that the method of connection to the network, and the network hardware【24】, must also be cheap.
A local area network links a number of computers and a number of servers which provide communal facilities, e. g. file storage. (A server usually includes a small microprocessor for control purposes. ) The computers and servers are known as stations. There are two methods of【25】in common use, rings and broadcast networks.
In the ring method(often called a Cambridge Ring) all the stations are linked in a ring,【26】includes one special station, the monitor station.
In broadcast networks, all the stations are【27】to a single linear cable(usually coax cable), and any transmission will be received by all stations.
【28】technology is used, local area networks are a development of the greatest importance.【29】as programming is simplified by an approach that thinks in terms of small procedures or programs, each doing a well-defined job, the computer system of tomorrow is likely to be【30】lots of small systems, each doing a specific job, linked by a local area network.

Can privacy be preserved 2 bringing safety and security to a world that seems increasingly 3 ？
Last month, Howard Schmidt, the nation's cyber-czar, offered the federal government a 4 to make the Web a safer place—a "voluntary trusted identity" system that would be the high-tech 5 of a physical key, a fingerprint and a photo ID card, all rolled 6 one. The system might use a smart identity card, or a digital credential 7 to a specific computer, and would authenticate users at a range of online services.
The idea is to 8 a federation of private online identity systems. User could 9 which system to join, and only registered users whose identities have been authenticated could navigate those systems. The approach contrasts with one that would require an Internet driver's license 10 by the government.
Google and Microsoft are among companies that already have these " single sign-on" systems that make it possible for users to 11 just once but use many different services.
12 , the approach would create a " walled garden" in cyberspace, with safe " neighborhoods" and bright "streetlights" to establish a sense of a 13 community.
Mr. Schmidt described it as a "voluntary ecosystem" in which "individuals and organizations can complete online transactions with 14 , trusting the identities of each other and the identities of the infrastructure 15 which the transaction runs. " Still, the administration's plan has 16 privacy rights activists. Some applaud the approach; others are concerned. It seems clear that such a scheme is an initiative push toward what would 17 be a compulsory Internet "drive's license" mentality.
The plan has also been greeted with 18 by some computer security experts, who worry that the "voluntary ecosystem" envisioned by Mr. Schmidt would still leave much of the Internet 19 . They argue that all Internet users should be 20 to register and identify themselves, in the same way that drivers must be licensed to drive on public roads.

As well as those chronic problems, the EU face an acute crisis in its economic core, the 16 countries that use the single currency. Markets have lost faith that the euro zone's economies, weaker or stronger, will one day converge thanks to the discipline of sharing a single currency, which denies uncompetitive members the quick fix of devaluation.
Yet the debate about how to save Europe's single currency from disintegration is stuck. It is stuck because the euro zone's dominant powers, France and Germany, agree on the need for greater harmonisation within the euro zone, but disagree about what to harmonies.
Germany thinks the euro must be saved by stricter rules on borrowing, spending and competitiveness, barked by quasi-automatic sanctions for governments that do not obey. These might include threats to freeze EU funds for poorer regions and EU mega-projects, and even the suspension of a country's voting rights in EU ministerial councils. It insists that economic co-ordination should involve all 27 members of the EU club, among whom there is a small majority for free-market liberalism and economic rigour ; in the inner core alone, Germany fears, a small majority favour French interference.
A "southern" camp headed by French wants something different: "European economic government" within an inner core of euro-zone members. Translated, that means politicians intervening in monetary policy and a system of redistribution from richer to poorer members, via cheaper borrowing for governments through common Eurobonds or complete fiscal transfers. Finally, figures close to the French, government have murmured, euro-zone members should agree to some fiscal and social harmonisation: e. g. , curbing competition in corporate-tax rates or labour costs.
It is too soon to write off the EU. It remains the world's largest trading block. At its best, the European project is remarkably liberal: built around a single market of 27 rich and poor countries, its internal borders are far more open to goods, capital and labour than any comparable trading area. It is an ambitious attempt to blunt the sharpest edges of globalisation, and make capitalism benign.
The EU is faced with so many problems that_________.
A．it has more or less lost faith in markets
B．even its supporters begin to feel concerned
C．some of its member countries plan to abandon euro
D．it intends to deny the possibility of devaluation

The modern university is the ideal environment for the creation and transfer of knowledge that drives national competitiveness in an increasingly global era. Its most effective form. is the American adaptation of the European model, in which teaching, leaning and research are integrated into a single institution. Indeed, the American university has proved capable of almost anything, from developing advanced economic theories to creating new life forms.
Many national leaders understand that the university is the critical catalyst for America's adaptability, economic robustness and emergence as a great power. And they are moving aggressively to catch up. The universities created by emerging economies beginning in the 1990s and through 2020 will likely play a decisive role in reshaping the global balance of economic power.
That is bad news for the United States. The past two decades of American university development have been characterized largely by self-satisfaction arising from steady progress by the top 20 or so research universities. And America as a nation has been coasting. Since 2000, the United States has lost its edge in the graduation of engineers and technologists. The country no longer dominates scientific discovery, innovation or exploration. Most important, the United States has not launched any effort to build new institutions to accommodate its increasingly diverse population of more than 300 million.
The result is that America's university system, despite its historical pre-eminence, has ceased to grow. Furthermore, America's university system has failed to adapt to the dramatic demographic shifts occurring as a result of social mobility and immigration.
America needs to realize that its universities face real competition from the rest of the world to attract the best and the brightest, to secure resources and to provide environments that educate and inspire. This is not to say that the best American universities are no longer the leaders in discovery and innovation. It is to say that the success of the higher-education system must be measured by more than just innovations. Its long-term performance depends on its ability to provide learning to a broad cross sections of citizens, to advance national proficiency in math and science and to create an adaptable work force, as well as to develop a national appreciation for discovery, entrepreneurship and the creative process.
In China and elsewhere, these are the goals of the new universities being built. In the United States, we need to move from a national self-confidence based on past success to one built on the knowledge that we are advancing a system of higher education that will meet our future needs. This will require that policymakers, business leaders and universities rededicate themselves to creating comprehensive learning and discovery environments; design entirely new models and methods for teaching, and then take action to implement them.
According to the author, US modern universities ______
A．is a perfect system which can deal with everything.
B．is a system which is developing rapidly.
C．is a trinity of teaching, learning and research.
D．is a place for innovation and creation.
