单项选择题

Suddenly, the economics of American suburban life are under assault as skyrocketing energy prices inflate the costs of reaching, heating and cooling homes on the distant edges of metropolitan areas. Just off Singing Hills Road, in one of hundreds of two-story homes dotting a former cattle ranch beyond the southern fringes of Denver, Phil Boyle and his family openly wonder if they will have to move close to town to get some relief.

They still revel in the space and quiet that has drawn a steady exodus from American cities toward places like this for more than half a century. But life on the edges of suburbia is beginning to feel untenable. Mr. Boyle and his wife must drive nearly an hour to their jobs in the high-tech corridor of southern Denver. With gasoline at more than $ 4 a gallon, Mr. Boyle recently paid $121 to fill his pickup truck with diesel fuel. In March, the last time he filled his propane tank to heat his spacious house, he paid $ 566, more than twice the price of 5 years ago.

Though Mr. Boyle finds city life unappealing, it is now up for reconsideration. "Living closer in, in a smaller space, where you don’t have that commute," he said, "It’s definitely something we talk about. Before it was’we spend too much time driving.’ Now, it’s ’we spend too much time and money driving.’ "

Across the nation, the realization is taking hold that rising energy prices are less a momentary blip than a change with lasting consequences. The shift to costlier fuel is threatening to slow the decades-old migration away from cities, while exacerbating the ’housing downturn by diminishing the appeal of larger homes set far from urban jobs. In Atlanta, Philadelphia, San Francisco and Minneapolis, homes beyond the urban core have been falling in value faster than those within, according to an analysis by Moody’s Economy. com. In Denver, housing prices in the urban core rose steadily from 2003 until late last year compared with previous years, before dipping nearly 5 percent in the last three months of last year, according to Economy. com. But house prices in the suburbs began falling earlier, in the middle of 2006, and then accelerated, dropping by 7 percent during the last three months of the year from a year earlier.

Many factors have propelled the unraveling of American real estate, from the mortgage crisis to a staggering excess of home construction. But economists and real estate agents are growing convinced that the rising cost of energy is now a primary factor pushing home prices down in the suburbs. More than three-fourths of prospective home buyers are now more inclined to live in an urban area because of fuel prices, according to a recent survey of 903 real estate agents with Coldwell Banker, the national brokerage firm.

From the first two paragraphs we can learn that().

A.soaring energy prices caused inflation in America

B.rising energy prices are threatening Phil’s cattle business

C.jumping fuel prices make suburban life costlier

D.shooting fuel costs make urban life unappealing

     A new problem has appeared in the world of technology- the mobile phone viruses. The first virus

called "Skulls" and "Dust", was discovered in July, 2004. Compared to computer viruses, these were

harmless, but proved that a virus could be spread across a mobile network.

     But as mobile phone technology moves forward, so do the viruses and the people who create them.

Now many people use "pocket computers" such as PDAs and "smart-phones" which can receive multimedia

messages in different forms like photos, videos, and music, and the most recent virus, "Cabir", is spread by

opening these kinds of multimedia messages. This virus gets into the mobile phone or PDA and then makes

it stop working. In only six months the virus has spread across almost 20 countries across the world-that

shows that it could easily get into millions of phones and PDAs.

     There are some viruses inside illegal (非法的) copies of games. These viruses take personal information

that is stored on someone's phone, and use it to make money for the people who sent the virus. Sometimes

the viruses have a programme that makes expensive phone calls to high cost numbers. The result is a very

high phone bill for the victim (受害者).

     In answer to this new threat (威胁), many new models of mobile phones and PDAs are now appearing

in stores with anti-virus software on them, just like computers.
