It is customary to regard the course of history as a great river, (31) its source in some small rivulet of the distant past, taking its rise (32) the plains of Asia, and flowing slowly down through the ages, gathering water fi’om new tributaries on the way, (33) finally in our own days broadens majestically over the whole world.

In face of the numbers of people who are suffering anxiety attacks over AIDS, global warming, ozone sharp decline, and the proliferation of chemical weapons, you have a disturbingly large population easily influenced by the madness aroused with the arrival of the period of the second thousand years.Even supposedly sober observers are taking positions in the millenarian parade. Novelist, poet, and science writer Brad Leithauser is convinced the second millennium is going to bring a "psychological shift" that will "literally redefine what it means to be a human being."Leithauser believes that global weather patterns will undergo random, even chaotic, changes produced by the dreaded greenhouse effect. In his novel Hence set around 2000, Leithauser visualizes religious leaders seizing on the resultant disturbances -flooded cities, soaring cancer rates, and what have you -and taking them as a sign that the end is near.At the same time, Leithauser thinks, a combination of high-speed living and runaway technology will serve further to alienate people from themselves. He predicts that invasive media will bring an inescapable large number of stimuli. In this atmosphere of "evershortening collective memory," books will become pass. Indeed, any form of reflective solitude will become "quietly sinful," says a character in Leithauser’s novel, and seeking it out will require "almost an act of social defiance."Economic expert Ravi Bartra is equally convinced that by the dawn of the second millennium people will have undergone a thorough spiritual and economic transformation. He warns that the voices of the rich will soon superheat the global economy to the point of explosion and collapse, in the wake of which "society will border on chaos. There will be a polarization of society into two classes -the haves and the have-nots -and there will be a lot of crime and street demonstrations" as the angry have-nots make strong claim for food, shelter, and social justice.But Batra, unlike Leithauser, sees the coming bimillennial breakdown as a sort of getting rid of sin by fire on the way to a better world. From the ashes of economic and social collapse, he says, will rise a "higher consciousness"--a climate in which pornography, selfishness, and extreme concentration of wealth are reproached and society becomes "more concerned with the handicapped and the weaker." On the job, he foresees "far more democratic large factories, where employees not only sit on boards of directors but actually run companies." Meanwhile, discipline will capture the home-and-family front, with "children obeying their parents more, and more family stability, fewer divorces.\ Ravi Batra is different in attitude toward the arrival of the second millennium from Brad Leithauser in that().

A. Leithauser is more positive.
Batra is more optimistic.
C. the former thinks more of the breakdown
D. the latter tends to look at the bright side of things

Print on paper is a little like democracy: the worst possible system except for all the others. Books are fragile, they are bulky, they are not easy to search through. They are certainly not suited to computerization. Yet printed volumes have endured half a millennium as readable as the day they came off the press, whereas digital data a mere 30 years old may have vanished past hope of retrieval.The film Into the Future: On the preservation of knowledge in the Electronic Age is itself an object lesson in how fast digital information becomes obsolete. One of the pioneering interactive-media companies whose workers and products appear on screen ceased operations shortly after being fihned. All the software whose images define "the Internet" is long since replaced.How fast do archivists have to run to stay in the same place Just plain data must be recopied onto new media every 10 years to stay ahead of physical deterioration and the junking of machines that can read outdated formats. Given this galloping obsolescence, it seems ironic that the film’s creators should have devoted a significant part of its time to the digitizing of paper archives. And yet they -and we -have no choice: the digital bug has infected us all, and interactive multimedia, with indexed and linked text, pictures and sound, have a convenience and impact that make conversion irresistible.The growing popularity of the World Wide Web offers some hope that publishers and archivists can format both old and new data in ways that will remain understandable for decades rather than months. But the Web brings its own complications. New, undescribed classes of collected information live on the Web in forms that confuse conventional notions of what a document is. How should -or can -such a single separate and independent existence be archived without potentially archiving the entire WebMany Web pages are not even fixed documents in the most basic sense. Two users who ask their Web browsers to open the same "document" may see quite different things on their screens. Besides, the fastest connections on the Internet transmit a mere 45 million bits per second, and so even a single snapshot of the trillion or more bytes available on the Web would take weeks of computer and network time. Meanwhile new sites spring up every day, and some existing sites change their information from minute to minute.In a sense, then, the Web has moved from a Newtonian to an Einsteinian model: it makes no more sense to speak of the state of the Web now than it does to speak of synchronizing clocks located far apart. By the time information has gone from here to there, it is already out of date.It seems strange that a medium intended for the widest possible distribution of knowledge should demonstrate the impossibility of acquiring complete information. Where the Web was once a map for finding useful information in the "real world," it is now a territory where that information, ever changing, resides. A suitable title for this review could be().

A. The Electronic Age.
B. Internet Complications.
C. Print on Paper: Out of Date.
D. Preserving the World.
