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.

Migration is usually defined as "permanent or semi-permanent change of residence". However, our concern is with movement between nations, not with internal migration within nations, although such movements often exceed international movements in volume. Today, the motives of people who move short distances are very similar to those of international migrants.
Students of human migration speak of "push" and "pull" factors, which influence an individual's decision to move from one place to another. Push factors are associated with the place of origin. A push factor can be as simple and mild a matter as difficulty in finding a suitable job, or as traumatic as war, or severe famine. Obviously, refugees who leave their homes with guns pointed at their heads are motivated almost entirely by push factors (although pull factors do influence their choice of destination).
Pull factors are those associated with the place of destination. Most often these are economic, such as better job opportunities or the availability of good land to farm. In general, pull factors add up to an apparently better chance for a good life and material well-being than is offered by the place of origin. When there is a choice between several attractive potential destinations, the deciding factor might be a non-economic consideration such as the presence of relatives, friends, or at least fellow countrymen already established in the new place who are willing to help the newcomers settle in.
Besides push and pull factors, there are what the sociologists call "intervening obstacles." Even if push and (or) pull factors are very strong they still may be outweighed by intervening obstacles, such as the distance of the move, the trouble and cost of moving, the difficulty of entering the new country, and the problems likely to be encountered on arrival. The decision to move is also influenced by "personal factors" of the potential migrant. The prospect of packing up everything and moving to a new and perhaps very strange environment may appear interesting and challenging to an unmarried young man and appallingly difficult to a slightly older man with a wife and small kids. Similarly, the need to learn a new language and customs may excite one person and frighten another. Regardless of why people move, migration of large numbers of people causes conflict. The United States and other western countries have experienced adjustment problems with each new wave of immigrants. It has usually taken several decades for each group to be accepted into the mainstream of society in the host country.
Today it is found that movement between nations often exceed international movements in volume.
