The Plaza closed for repair in When it reopened two years later,more than half of it had been changed into one of these modern condo hotels.
Here&39;s how it works: You buy what equals to an apartment(公寓). If it&39;s at&39;The Plaza,it will cost you between $ 1.5million and $9 mllion. So you own a part of the building. But there&39;s some inconvinience. You may stay there no more than 120 days a year. hereion. The rest of the time,the hotel&39;s workers can book guests into your place, just as they would in the regular hotel&39;s rooms. So if you&39;re lucky and rich,you can now live in really special quarters up to almost one thid of the year. While others pay off your mortgage(房贷)the rest of the year.
So far,a great monry of the nation&39;s condo hotel units have been purchased not by rich people but richer companiesm, including foreign ones. They want a nice place for their bosses to stay when they are in town or working late at the office.

The telecity is a city whose life, direction, and functioning are largely shaped by telecommunications. In the twenty first century, cities will be based more and more on an economy that is dependent on services and intellectual property. Telecommunications and information networks will define a city's architecture, shape, and character. Proximity in the telecity will be defined by the speed and bandwidth of networks as much as by geographical propinquity. In the age of the telecity, New York and Singapore may be closer than, say, New York and Arkadelphia, Arkansas.
Telecities will supersede megacities for several reasons, including the drive toward clean air, reducing pollution, energy conservation, more jobs based on services, and coping with the high cost of urban property. Now we must add the need to cope with terrorist threats in a high-technology world.
Western mind-sets were clearly jolted in the wake of the terrorist attack on the World Trade Center in New York City and attacks in Indonesia, Saudi Arabia, and else where. But the risks posed by twentieth-century patterns of urbanization and architecture have ye to register fully with political figures and leaders of industry. The Pentagon, for example, has been rebuilt in situation rather than distributed to multiple locations and connected by secure landlines and broadband wireless systems. Likewise, the reconstruction of the World Trade Center complex still represents a massive concentration of humanity and infrastructure. This is a remarkably shortsighted and dangerous vision of the future.
The security risks, economic expenses, and environmental hazards of over-centralization are everywhere, and they do not stop with skyscrapers and large governmental structures. There are risks also at seaports and airports, in food and water supplies, at nuclear power plants and hydroelectric turbines at major dams, in transportation systems, and in information and communications systems.
This vulnerability applies not only to terrorist threats but also to human error, such as system-wide blackouts in North America in August 2003 and in Italy in September 2003, and natural disasters such as typhoons, hurricanes, floods, and earthquakes. Leaders and planners are only slowly becoming aware that overcentralized facilities are the most vulnerable to attack or catastrophic destruction.
There is also growing awareness that new broadband electronic systems now allow governments and corporations to safeguard their key assets and people in new and innovative ways. So far, corporations have been quickest to adjust to these new realities, and some governments have begun to adjust as well.
Which of the following statements is true according to the passage？
A．The telecity is a TV manufacturing city.
B．The telecity is a city of the speed and bandwidth of networks.
C．Singapore is closer to New York than Arkadelphia, Arkansas is in telecity age.
D．Singapore is actually closer to New York than Arkadelphia, Arkansas.
