问题     Throughout the twentieth century, from 1900 onwards, people have dreamt of the technological advances that the advent of the new millennium would bring. They envisioned a world of flying cars, where high-tech gadgets were a part of every aspect of life. The year 2000 has now come and gone and, while flying cars are still left to the realm of the imagination, the infusion of technology into all areas of life has indeed become a reality.
    Leading the technological change is the ever-present computer. In the United States, fully one-half of all households are connected to the Internet, and the pace is rapidly increasing, with 700 more households becoming connected every hour. The computer industry has produced over one million new jobs, spurring rapid, unprecedented growth in economic output and prosperity. The growing effects of computers on business go even deeper, however. In 1999, 27% of companies monitored their employees, email activities in some form, and by 2000 the number had grown to 38.2%, indicating the growing importance of electronic communication in business. The younger generations are becoming indoctrinated into the computer culture as well: In the United States alone, 424 million educational CD-ROMs were purchased, making computers and other forms of high-technology integral elements in the education system.
    In 1990, 20% of the average company’s business investment expenditures consisted of computers and other high-tech equipment; By 1998 the figure had grown to 40% of total business investment expenditures, and the figure is only expected to grow in the future. The technological revolution does not end with computers, however. It is estimated that by the year 2005, 1.6 billion mobile phones will be in use, keeping people connected to one another all the time no matter where they are.
    For better or for worse, technology takes part in every aspect of our lives, from the moment we wake up until the time we go to bed. Whether we like it or not, we have come to rely on its conveniences, to the point of almost forgetting that it’s even there. One cannot escape the far-reaching grip of technology even when on vacation. Every second, 2,700 photos are taken with the latest cameras, and 80% of those snapshots are taken by people on vacation. No matter where one goes, no matter how far from urban centers, technology has become a basic element of everyday life. Flying cars or no flying cars, the future is here, and technology is the name of the game.

选项 A、illustrate the positive impacts of technology on daily life
B、identify and detail the rapid infusion of high-technology into vital aspects of daily life
C、inform the reader as to the current status of technology
D、persuade the reader that technology characterizes the future

解析 属主旨思想题。文章第一段最后一句指出：……将科技注人生活的方方面面的确已成为现实。第二、三段以数据说明“领导这次技术革新的是无处不在的计算机”。第四段指出“未来离不开高科技产品”。由此可知，选项D正确。选项A、B、C都是文中细节，不是中心。
