阅读理解-How many U.S.households have linked to Internet today?

　　Excerpt 1　　Internet is a vast network of computers that connects many of the world’s businesses, institutions, and individuals.The internet, which means interconnected network of networks, links tens of thousands of smaller computer networks.These networks transmit huge amounts of information in the form of words, images, and sounds.　　Excerpt 2　　Wild Bill Donovan would have loved the Internet.The American spymaster who built the Office of Strategic Services in the World War Ⅱ and later laid the roots for the CIA was fascinated with information.Donovan believed in using whatever tools came to hand in the “great game” of espionage—spying as a “profession”.These days the Net, which has already remade pastimes as buying books and sending mail, is reshaping Donovan’s vocation as well.　　Excerpt 3　　Today, the computer has taken up appliance status in more than 42 percent of households across the United States.And these computers are increasingly biting wired to the Internet.Online access was up more than 50 percent in just the past year.Now, more than one quarter of all U.S.households can surf in cyberspace.　　Excerpt 4　　Computer ownership and Internet access are highly classified along lines of wealth, race, education, and geography.The data indicates that computer ownership and online access are growing more rapidly among the most prosperous and well educated: essentially, wealthy white people with high school and college diplomas and who are part of stable, two-parent households.The highest income bracket households, those earning more than $75000 annually, are 20 times as likely to have access to the Internet as households at the lowest income levels, under $10000 annually.The computer-penetration rate at the high-income level is an amazing 76.56 percent, compared with 8 percent at the bottom end of the scale.　　Excerpt 5　　But the experts noted the easy access to the Internet also means anyone can post information for others to see.“Anyone can say anything they want, whether it’s right or wrong,” said Case.Readers have to determine for themselves who to trust.“In a world of almost infinite voices, respected journalists and respected brand names will probably become more important, not less,” Case said.　　“The Internet today is about where radio was 80 years ago, or television 50 years ago or cable 25 years ago,” he said.But it is growing rapidly because it provides people fast access to news and a chance to comment on it.　　Excerpt 6　　In the future, the Internet will probably grow more sophisticated as computer technology becomes more powerful.Many experts believe the Internet may become part of a larger network called the information superhighway.This network, still under development, would link computers with telephone companies, cable television stations, and other communication systems.People could bank, shop, watch TV, and perform many other activities through the network.
