From a long-term perspective, Internet shopping is but a low-level aspect of the Net, and it is not likely to become the most important trend. After all, most merchandise is unsuitable for Internet shopping. Besides, if everyone shops on the Net, what will happen to the hundreds and thousands of shopping malls? Therefore, the second aspect of the Net will be more important. Its significance goes beyond that of connecting businesses. There have been reports of simultaneous consultation of doctors from all over the world on the Internet. These are early examples of high-level networking.

It is estimated that the new synergy between computers and Net technology will have significant influence on the industry of the future. The sheer power of electronic commerce (e-commerce) will change the face of trade dramatically. Sporting Goods Company Puma was on the verge of bankruptcy back in 1992. From 1993, Puma began to diffuse its production, logistics and marketing divisions to 80 Net enterprises worldwide, and the results were spectacular. Puma was transformed from a sickly feline into a magnificent beast. The reason for this transformation is that intra-and inter-business electronic links greatly increase the efficiency of production, planning, the collecting of information and data exchange. As the business is rapidly being rationalized, production figures go up while costs come down.

The development of e-commerce may well bring the world into a brand-new era of electronic currency. With the emergence of a phantom electronic currency, every one of us would be affected. At the moment, developed areas in Europe, the United States and Asia have already started studying the possibility of an electronic currency. Electronic currency is not only about currency. It refers to an entire finance system of the world.

Questions 48 to 50 are based on the following passage:

The longitudinal (纵向的) study demonstrates that students who receive ESL (English as a second language) instruction are far better than those taught primarily in their native language. A comparison of the three-year exit rates for students in ESL and bilingual programs shows that those who receive ESL instruction test out faster and in higher percentages than those who receive instruction in their native language, regardless of the grade in which they entered school. For example, 79.3 percent of the children who entered ESL programs in kindergarten tested out, while only 51.5 percent of those who received their education in their native languages did. Likewise, 72.9 percent of the LEP(limited English proficiency) students who entered programs in the first grade tested out, while only 38.5 of those in bilingual programs did. For students who entered LEP programs in the ninth grade, 91.6 percent of those in native-language instruction classes still hadn’t tested out after three years, as compared with 78.1 percent of those in ESL classes.
