C At one time, puters were expected largely to remove the need for paper copies of documents(文件 ) because they could be stored electronically. But for all the texts that are written, stored and sent electronically, a lot of them are still ending up on paper. It is difficult to measure the quantity of paper used as a result of use of Interconnected puters, although just about anyone who works in an office can tell you that when is introduced, the printers start working overtime. “I feel in my bones this revolution is causing more trees to be cut down,” says Ted Smith of the Earth Village Organization. Perhaps the best sign of how puter and Inter use pushes up demand for paper es from the hightech industry itself, which sees printing as one of its promising new markets. Several Inter panies have been set up to help small businesses print quality documents from a puter. Earlier this week HewlettPackard Co. announced a plan to develop new technologies that will enable people to print even more so they can get a hard copy of a business document, a medical record or just a online , even if they are nowhere near a puter. As the pany sees it, the more use of the Inter the greater demand for printers. Does all this mean environmental concerns have been fotten? Some activists suggest people have been led to believe that a lot of dangers to the environment have gone away. I guess people believe that the problem is taken care of, because of recycling(回收利用 ), said Kelly Quirke, director of the Rainforest Action Network in San Francisco. Yet Quirke is hopeful that hightech may also prove helpful. He says printers that print on both sides are growing in popularity. The action group has also found acceptable paper made from materials other than wood, such as agricultural waste. 49. The growing demand for paper in recent years is largely due to ______. A. the rapid development of small businesses B. the opening up of new markets C. the printing of high quality copies D. the increased use of the Inter 50. Environmentalists believe one possible way of dealing with the paper situation is ______. A. to encourage printing more quality documents B. to develop new printers using recycled paper C. to find new materials for making paper D. to plant more fastgrowing trees 51. HewlettPackard Co. has decided to develop new technologies because ______. A. people are concerned about the environment B. printers in many offices are working overtime C. small panies need more hard copies D. they see a growing market for printers 52. What would be the best title for the text? A. Computers and Printers. B. Email and the Business World. C. Inter Revolution and Environment. D. Modern Technology and New Markets. D Often people use laptops on trains and airplanes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms. Westlake College in Virginia will start a laptop puter program that allows students to do schoolwork anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are part of a $10 million puter program at Westlake, a 110yearold college. The students with laptops will also have access to the Inter. Besides, they will be able to use to “speak” with their teachers, their classmates and their families. However, the most important part of the laptop program is that students will be able to use puters without going to puter labs. They can work with it at home, in a fastfood restaurant or under the trees—anywhere at all! Because of the many changes in puter technology, laptop use in higher education, such as colleges and universities, is workable(
