1.Today in the United States, there are over 22 million adults using the Web, about half of whom access the Internet at least once a day. Meanwhile, the variety of activities on the Web is broadening at an amazing rate. There is almost no topic about which you cannot find fairly interesting material on the Web. Many of these sites are getting excellent traffic flow. Want to buy a dog? Or sell a share? Or order a car? Use the Internet. nextup home N 2.Where are we going to get the time to live with the Web? In some instances, people will actually save time because the Web will make doing things more efficient than in the past, being able to get information about a major purchase, for example, or finding out how much your used car is worth, or what your cheapest way of getting to Florida is. That is easy to find on the Web, even today. nextup home In other instances, people will trade the time they now spend reading the paper, or watching television, for information or entertainment they will find on the computer screen. Americans, particularly young ones, will spend less time in front of a television, more on the Web. nextup home 3. One great benefit of the Web is that it allows us to move information online that now resides in paper form. Several states in America are using the Web in a profound way. You can apply for various permits or submit applications for business licenses. Some states are putting up listings of jobs- not just states government jobs, but all the jobs available in the state. I believe, over time, that all the information that governments print, and all those paper forms they now have, will be moved on to the Internet. nextup home 4.Electronic commerce notches up month by month, too. It is difficult to measure, because a lot of electronic commerce involves existing buyers and sellers who are simply moving paper- based transactions to the Web. That is not new business. Microsoft, for example, purchases millions of dollars of personal computers (PC) online instead of by paper. However, that is not a fundamental change; it has just improved the efficiency of an existing process. nextup home N The biggest impact has occurred where electronic commerce matches buyers and sellers who would not previously have found each other. When you go to a book site and find an obscure book that you never would have found in a physical bookstore, that is a new type of commerce. nextup home 5. Today, about half of all PCs are still not connected to the Web. Getting communications cost down and making all the software simple will bring in those people. And that, in turn, will move us closer to the critical mass that will make the Web lifestyle everyones lifestyle. One element people underestimate is the degree to which the hardware and software will improve. nextup home Just take one aspect: screen technology. I do my e-mail on a 20-inch liquid crystal display (LCD) monitor. It is not available at a reasonable price yet, but in two years it will be. In ten years, a 40-inch LCD with much higher resolution will be commonplace. nextup home 6. The boundary between a television set an a PC will be blurred because even the set-top box that you connect up to your cable or satellite will have a processor more powerful than what we have today in the most expensive PC. This will, in effect, make your television a computer. nextup home 7. Interaction with the Web will also improve, making it much easier for people to be involved. Today the keyboards we use to search the Web often return to too many articles to sort through, many of them out of context. If you want to learn about the fastest computer chip available, you might end up getting responses instead about potato chips being delivered in fast trucks. nextup home In the future, we shall be either speaking or typing sentences into the computers, not potatoes. Speech recognition also means that you will be able to call in on a phone and ask if you have any new messages, or check on a flight, or check on the weather. nextup home 8. To predict that it will take over ten years for these changes to happen is probably pessimistic. We usually overestimate what we do in two years and underestimate what we can do in ten. The Web will be as much a way of life as the car by 2008. perhaps before. nextup home N back home next access: n. 进入，通道 n. 使用,接近 vt. 使用，接近，存取 e.g. There is no access to the street through that door. 穿过那个门没有通向大街的路。 e.g. Before liberation, the laboring people had no access to education. 解放前，劳动人民没有受教育的机会。 e.g. home up Accumulators and index registers can be accessed by the programmer. 程序员可以对累加器和变址寄存器进行存取。 back back home next submit: vt. 使.变糊涂,污损, 涂污, 弄脏 vi. 沾染污迹,变模糊 blur out: 弄模糊，抹掉 e.g. Tears blurred his eyes. 眼泪使他的眼睛模糊 e.g. The moths tapped and blurred at the window screen. 飞蛾在窗帘上跳来跳去, 弄上了许多污点。 back home Live with: v. 寄宿在.家,与.同居,承认, 忍受( 不愉快的事) e.g. By the way, do you live with your parents or have a place of your own?.
