Cosmology is sometimes pooh-poohed as
more philosophy than science. It asks deep questions about nature but provides
unsatisfyingly vague answers. The cosmos may be 12 billion years old, but it
could be as much as 15 billion. The stars began to shine 100 million years after
the Big Bang, or maybe it’s a billion. "Our ideas," acknowledges Max Tegmark of
the University of Pennsylvania, "have been kind of wobbly."
But
much of the wobble has been fixed, thanks to a satellite known as the Wilkinson
Microwave Anisotropy Probe, or WMAP. Since July 2001, WMAP has been orbiting in
deep space, more than a million kilometers from Earth, studying the most ancient
light in existence. And in a dramatic reminder that important space science is
almost always done by machines, not fragile humans, it reported a series of
A. WMAP’s findings are quite convincing and he accepted them.
B. WMAP will solve all the problems that have puzzled cosmologists.
C. WMAP’s findings accord with Einstein’s concept of space-time.
D. We may ignore some strange measurements in WMAP’s data.

[单项选择] TEXT B For about three centuries we have been doing science, trying science out, using science for the construction of what we call modern civilization. Every dispensable item of contemporary technology, from canal locks to dial telephones to penicillin, was pieced together from the analysis of data provided by one or another series of scientific experiments. Three hundred years seems a long time for testing a new approach to human development long enough to settle back for critical appraisal of the scientific method, maybe even long enough to vote on whether to go on with it or not. There is an argument. Voices have been raised in protest since the beginning, rising in pitch and violence in the nineteenth century during the early stages of the industrial revolution, summoning urgent crowds into the streets any day these days on the issue of nuclear energy. Give it back, say some of the voices, it doesn’t really work, we’d tried A. Many valuable items were produced in the past. B. Man supports scientific progress unanimously. C. Some held hostile attitude toward science in the past. D. Three hundred years is not long enough in science.
[简答题]Text B
In recent years American society has become increasingly dependent on its universities to find solutions to its major problems. It is the universities that have been charged with the principal responsibility for developing the expertise to place men on the moon; for dealing with our urban problems and with our deteriorating environment; for developing the means to feed the world’s rapidly increasing population. The effort involved in meeting these demands presents its own problems. In addition, this concentration on the creation of new knowledge significantly impinges on the universities’ efforts to perform their other principal functions, the transmission and interpretation of knowledge ---- the imparting of the heritage of the past and the preparing of the next generation to carry it forward.
With regard to this, perhaps their most traditionally sanctioned task, colleges and universities today find themselves in a serious bind generally. On the one hand, there is the
A. A．creating new knowledge
B．providing solutions to social problems
C． making experts on sophisticated industries out of their students
D．preparing their students to transmit inherited knowledge
[单项选择] {{B}}TEXT B{{/B}} Affirmative action may not
be the most divisive issue on the ballot, but it remains an unending source of
conflict and debate at least in Michigan, whose citizens are pondering a
proposal that would ban affirmative action in the public sector. No one knows
whether other states will follow Michigan’s lead, but partisans on both sides
see the vote as crucial--a decision that could either help or hinder a movement
aimed at ending "preferential treatment" programs once and for all.
Ward Connerly has no doubts about the outcome. "Them may be some ups and
downs.., with regard to affirmative action, but it’s ending," .says Connerly,
the main mover behind the Michigan proposal, who pushed almost identical
propositions to passage in California 10 years ago and in Washington state two
years later. His adversaries are equally passionate. "I just want to shout from
the rooftops, ’This isn’t good for America’," says Mary A. Approval. B. Disapproval. C. Objective. D. Difficult to tell.

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 an excuse for
expounding on Black history. Addison Gayle’s recent work, for example, judges
the value of Black fiction by overtly political standards, faring each work
according to the notions of Black identity which it put forward.
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 limits much of
the fictional enterprise. Rosenblatt’s literary analysis discloses relations and
connotations among works of Black ficti
A. evaluating the soundness of a work of criticism.
B. comparing various critical approaches to a subject.
C. discussing the limitations of a particular kind of criticism.
D. summarizing the major points made in a work of criticism.
