The past 40 years have witnessed an extraordinary evolution. From slow expensive machines controlled by punched cards, computers have become low-cost, powerful units taking up no more space than a briefcase. Simultaneously, our world has become interlaced with telephone wires, optic fibers, undersea cables, microwave links, television channels and satellite communications.
At the crossing of these two developments stands the Internet—a direct result of computer technology intersecting with communication technology. But for many in the world of today’s media, this is merely a first landmark in what promises to be a giant upheaval in the way people communicate, relax and work. This is the era of digital convergence.
According to a recent article in Scientific American, convergence is in principle "the union of audio, video and data communications into a single source, received on a single device, delivered by a single connectio
A. develops with the advance of computer technology.
B. combines computer technology and communication technology.

Many people are afraid to assert themselves, Dr. Alberti, author of Stand Up, Speak Out, and Talk Back, thinks it’ s because their self - respect is low. "Our whole set-up is designed to make people distrust themselves, "says Alberti, "There’ s always ’ superior’ around a parent, a teacher, a boss who ’ knows better’. There superiors often gain when they chip away at your self - image."
But Alberti and other scientists are doing something to help people assert themselves. They offer "assertiveness training" courses, AT for short. In the AT courses people learn that they have a right to be themselves. They learn to speak out and feel good about doing so. They learn to be more active without hurt
A. positive
B. negative
C. hostile
D. appreciative

In the past, American colleges and universities were created to serve a dual purpose to advance learning and to offer a chance to become familiar with bodies of knowledge already discovered to those who wished it. To create and to impart, these were the distinctive features of American higher education prior to the most recent, disorderly decades of the twentieth century. The successful institution of higher learning had never been one whose mission could be defined in terms of providing vocational skills or as a strategy for resolving societal problems. In a subtle way Americans believed higher education to be useful, but not necessarily of immediate use.
Another purpose has now been assigned to the mission of American colleges and universities. Institutions of higher learning—public or private—commonly face the challenge of defining their programs in such a way as to contribute to the service of the community.
This service role
A. radical.
B. impartial.
C. optimistic.
D. supportive.
