[简答题]
In reading the pages of American Scientist, I have been struck by the stunning progress being made in science and engineering, new phenomena discovered, new materials synthesized, new methods developed. (46) What I see behind many of these exciting stories is the widespread and even revolutionary use of distributed intelligence that is made possible by the "wiring" of the scientific community. It is more than a time saver or a communication enhance; it is enabling us to think in new ways and its impact on society may be monumental.
The term "information age" probably does not do justice to the possibilities of this emerging era. (47) This is an age of "knowledge and distributed intelligence", in which knowledge is available to anyone, located anywhere, at any time; and in which power, information, and control are moving from centralized systems to individuals. This era calls for a new form of leadership and vision from the acade

[单项选择]Roger Rosenblatt’ s book Black Fiction, in attempting to apply literary rather than sociopolitical criteria to its subject, successfully alters the approach taken by most previous studies. As Rosenblatt notes, criticism of Black writing has often served as a pretext for expounding on Black history. Addison Gayle’ s recent work, for example, judges the value of Black fiction by overtly political standards, rating each work according to the notions of Black identity which it introduces.
Although fiction assuredly springs from political circumstances, its authors react to those circumstances in ways other than ideological, and talking about novels and stories primarily as instruments of ideology outwits much of the fictional enterprise. Rosenblatt’ s literary analysis discloses affinities and connections among works of Black fiction which solely political studies have overlooked or ignored.
Writing acceptable criticism of Black fiction, however, presupposes giving satisfactory
A. An analysis of the influence of political events on the personal ideology of Black writers.
B. A critical study that applies sociopolitical criteria to autobiographies by Black authors.
C. A literary study of Black poetry that appraises the merits of poems according to the political acceptability of their themes.
D. An examination of the growth of a distinct Black literary tradition within the context of Black history.

[单项选择]It may be just as well for Oxford University’s reputation that this week’s meeting of Congregation, its 3,552-strong governing body, was held in secret, for the air of civilized rationality that is generally supposed to pervade donnish conversation has lately turned fractious. That’s because the vice-chancellor, the nearest thing the place has to a chief executive, has proposed the most fundamental reforms to the university since the establishment of the college system in 1249; and a lot of the dons and colleges don’t like it.
The trouble with Oxford is that it is unmanageable. Its problems-the difficulty of recruiting good dons and of getting rid of bad ones, concerns about academic standards, severe money worries at some colleges-all spring from that. John Hood, who was recruited as vice-chancellor from the University of Auckland and is now probably the most-hated antipodean in British academic life, reckons he knows how to solve this, and has proposed to reduce the power of do
