工程硕士研究生英语基础教程;Table of Contents;Text A: Future of Net Economy ;[1] As we have entered the new century, human society is beginning its move from the industrial economy into the knowledge-based economy. In more specific terms, the application of information to the economy is best exemplified in the networking of communication, or the so-called Net economy. This Net refers to the computer network of satellites, optic fibers, cables and telephone lines that connect the whole world. ;[1]当我们步入新世纪的时候，人类社会正开始由工业经济向知识型经济转变。具体地说，经济中信息的应用主要是反映在通讯的网络化，也就是所谓的网络经济。该网络就是指由卫星、光纤、电缆和电话线路将世界各个角落连接在一起的电脑网络。;[1] With the click of a mouse, information from the other end of the globe will be transported to your computer screen at the dizzying speed of seven-and-a-half times around the earth per second. Generally, there are two aspects of the Net. One is the networking between businesses and their customers. The other is the networking between individual businesses, or the regional and even global networking between industrial production and scientific research. Internet shopping belongs to the first aspect.;[1] 只要用鼠标一点，在地球另一端的信息马上就会以每秒钟绕地球七周半的惊人速度传输到你的电脑屏幕上。网络化大致可分成两个方面：其一是企业与客户之间的网络化。另外一个则是企业间的网络化，或者是工业生产和科学研究之间的地区性甚至全球性的网络化。网上购物就属于第一个方面。;[2] 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? ;[2]从长远来看，网上购物仅仅是低层次的网络化，未必会成为最主要的趋向。毕竟大多数商品并不适合于网上购物。此外，如果大家都在网上购物，那么成千上万的购物中心该怎么办呢？;[2] 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.;[2] 所以说，网络化的第二个方面将更加重要。它的重要性远远超过了商务联络。媒体曾报道过世界各地的医生利用国际互联网同时会诊。这些是高层次网络化的初期
