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.

Many of the chronic diseases risk and the diseases themselves overlap. In developed countries, cancer is the second-biggest cause of death after cardiovascular disease (CVD), and epidemiological evidence points to this trend emerging in the less developed world. This is particularly true in countries of "transition" or middle income countries such as in South America and Asia. Already more than half of all cancer cases occur in developing countries. There are approximately 20 million people living with cancer at the moment; by 2020 there will an estimated 30 million. And the impact is far greater than the number of cases alone would suggest.【2】Regardless of prognosis, the initial diagnosis is of- ten perceived by patients as life-threatening, with over one-third of sufferers experiencing clinical anxiety and depression. Cancer can also be profoundly distressing as well as economically disruptive to patients' families. The clinical care of cancer patients is a costly element in public health budgets. 【3】Dietary factors are estimated to account for approximately 30% of cancers in Western countries, making diet second only to tobacco as a preventable cause of cancer. This proportion is thought to be about 20% in developing countries and is projected to grow. As developing countries become urbanized, patterns of cancer, particularly those most strongly associated with diet and physical activity, tend to shift towards the patterns of economically developed countries. Cancer rates also change as populations move between countries and adopt different dietary patterns. The relative importance of cancers as a cause of death is increasing. The incidence of lung cancer and cancers of the colon and breast generally increases in parallel with economic development, as stomach cancer declines. Cancer is also strongly associated with social and economic status. Cancer risk factors are highest in groups with the least education. In addition, patients in the lower socioeconomic classes have consistently poorer survival rates than those in higher social class. In recent years, substantial evidence has pointed to the link from overweight and obesity, to many types of cancer such as breast and kidney.【4】The composition of the diet is also important since fruit and vegetables may have a protective effect by decreasing the risk for some cancer types such as oral and gastric cancer. Regular physical activity has also been seen to have a protective effect in reducing the risk of breast cancer. High intake of preserved meat or red meat might be associated with increased risk of colorectal cancer. Another aspect of diet clearly related to cancer risk is the high consumption of alcoholic beverages, which convincingly increase the risk of oral cavity, liver and breast cancers. The wealth of knowledge that already exists about cancer risk factors provides obvious and ample scope for action to reduce the cancer burden of all countries. After tobacco, overweight and obesity seems to be the most important avoidable cause of cancer. 【5】Given that poor nutrition, physical inactivity, obesity tobacco and alcohol are risk factors common to other chronic diseases such as CVD, type 2 diabetes, and respiratory diseases, conducting a cancer prevention program withi
