根据以下内容，回答下列各题。 Internet use appears to cause a drop in psychological health, a

ccording to research at Carnegie Mellon University. Even people who spent just a few hours a week on the Internet experienced more bad feelings and loneliness than those who was online less frequently, the two-year study showed. Researchers are puzzling over the results, which were completely contrary to their expectations. They expected that the Net would prove socially healthier than television, since the Net allows users to choose their information and to communicate with others. The fact that Internet use reduces time available for family and friends may account for the drop in psycho logical health, researchers hypothesized (推测). Faceless, bodiless "virtual" (虚的) communication may be less psychologically satisfying than actual conversation, and the relationships formed through it may be shallo wer. Another possibility is that exposure to the wider world through the Net makes users less satisfied with their lives. "But its important to remember this is not about the technology, its about how it is used," says psychol- ogist Christine Riley of Intel, one of the studys sponsors (发起人). "It really points to the need for considering social factors in terms of how you design applications and services for technology. " Whats the finding of the research undertaken at Carnegie Mellon University？

A.People spend more time on the Internet now.

B.People spend less time with their families and friends now.

C.The Net proves socially healthier than television.

D.lnternet use may cause a drop in psychological health.

根据下列短文，回答下列各题。 Whats hot for 2007 among the very rich？ A $7.3 million diamo

nd ring. A trip to Tanzania to hunt wild animals. Oh, and income inequality. Sure, some leftish billionaires like George Soros have been railing against income inequality for years. But increasingly, centrist and right-wing billionaires are starting to worry about income inequality and the fate of the middle class. In December, Mortimer Zuckerman wrote a column in U.S. News & World Report, which he owns. "Our nations core bargain with the middle class is disintegrating," lamented (哀叹) the 117th-richest man in America."Most of our economic gains have gone to people at the very top of the income ladder. Average income for a household of people of working age, by contrast, has fallen five years in a row." He noted that "Tens of millions of Americans live in fear that a major health problem can reduce them to bankruptcy." Wilbur Ross Jr. has echoed Zuckermans anger over the bitter struggles faced by middle-class Americans. "Its an outrage that any Americans life expectancy should be shortened simply because the company they worked for went bankrupt and ended health-care coverage," said the former chairman of the International Steel Group. Whats happening？ The very rich are just as trendy as you and I, and can be so when it comes to politics and policy. Given the recent change of control in Congress, the popularity of measures like increasing the minimum wage, and efforts by Californias governor to offer universal health care, these guys dont need their own personal weathermen to know which way the wind blows. Its possible that plutocrats (有钱有势的人) are expressing solidarity with the struggling middle class as part of an effort to insulate themselves from confiscatory (没收性的) tax policies. But the prospect that income inequality will lead to higher taxes on the wealthy doesnt keep plutocrats up at night. They can live with that. No, what they fear was that the political challenges of sustaining support for global economic integration will be more difficult in the United States because of what has happened to the distribution of income and economic insecurity. In other words, if middle-class Americans continue to struggle financially as the ultrawealthy grow ever wealthier, it will be increasingly difficult to maintain political support for the free flow of goods, services, and capital across borders. And when the United States places obstacles in the way of foreign investors and foreign goods, its likely to encourage reciprocal action abroad. For people who buy and sell companies, or who allocate capital to markets all around the world, thats the real nightmare. What is the current topic of common interest among the very rich in America？

A.The fate of the ultrawealthy people.

B.The disintegration of the middle class.

C.The inequality in the distribution of wealth.

D.The conflict between the left and the right wing.
