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 Internet-connected computers, although just about anyone who works in an office can tell you that when e-mail 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 computer and Internet use pushes up demand for paper comes from the high-tech industry itself, which sees printing as one of its promising new markets. Several Internet companies have been set up to help small businesses print quality documents from a computer. Earlier this week Hewlett-Packard 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 one-line e-mail, even if they are nowhere near a computer. As the company sees it, the more use of the Internet the greater demand for printers.Does all this mean environmental concerns(环境问题) have been forgotten? 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 high-tech 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.1. 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 marketsC. the printing of high quality copies D. the increased use of the Internet2. 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 paperC. to find new materials for making paper D. to plant more fast-growing trees3. Hewlett-Packard Co. has decided to develop new technologies because _.A. people are concerned about the environment B. printers in many offices are working overtimeC. small companies need more hard copies D. they see a growing market for printers4. What would be the best title for the text?A. Computers and Printers. B. E-mail and the Business World.C. Internet Revolution and Environment. D. Modern Technology and New Markets.语法讲解-现在完成时的被动语态一、结构 :主语+have/hasbeen及物动词的过去分词二、用法1. 表示被动的动作发生在说话之前，并强调对现在造成的影响或结果。如：The door has been locked.门被锁上了。(结果是现在没有人能进去)2表示一个被动的动作或状态开
