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.
In paragraph 4, "For better or for worse, technology takes part in every aspect of our lives ... means that______.

选项 A、technology has had both positive and negative effects thus far
B、the full impact and implications of high-technology in daily life is yet to be determined
C、our lives are continually characterized by the technological elements associated with them
D、without technology, daily life would not reasonably be carried out

答案B

解析 属信息推断题。相关信息在第四段第一句:不管怎样,科技渗透到我们生活中的每一部分,……。接下来的句子进行了具体说明:无论我们喜欢与否,我们都已经逐步地依赖上了它给我们带来的诸多便利……。人们甚至连度假的时候也逃脱不了高科技无所不及的控制……。由此可推知,选项B正确(高科技对我们日常生活的影响和意义还需要再确定)。选项A与本段不符(没有提到负面影响);选项C与第一句及倒数第二句内容不符;选项D无法从文中推出。
