[填空题]
Glass, in one form or another, has long been in noble service to humans. As one of the most widely used of manufactured materials, and certainly the most versatile, it can be as imposing as a telescope mirror the width of a tennis court or as small and simple as a marble rolling across dirt.
41. ______
The uses of this adaptable material have been broadened dramatically by new technologies: glass fiber optics—more than eight million miles—carrying telephone and television signals across nations; glass ceramics serving as the nose cones of missiles and as crowns for teeth; tiny glass beads taking radiation doses inside the body to specific organs; even a new type of glass fashioned of nuclear waste in order to dispose of that unwanted material.
42. ______
On the horizon are optical computers. These could store programs and process information by means of light—pulses from tiny lasers—rather than electrons. And the pulses woul -

[单项选择]A key reason the news media exists with special privileges is to be our watchdogs. Reporters’ charge is to alert us when something is wrong, when human or natural disasters are about to threaten our welfare. When it comes to natural disasters, the news media do a praisable job of reporting the obvious, but not a very good one of preparing the public for what might happen, for alerting us to potential difficulties. When it comes to human disasters, especially problems in government and economic matters, the press has failed miserably. For example, Time magazine finally told the public in a recent cover story what only the most quick observers already knew: "The Great Retirement Ripoff (偷窃): Millions of Americans who think they will retire with benefits are going be shocked. How corporations are picking people’s pockets—with the help of Congress...How can this legal"

[单项选择]The modern university is the ideal environment for the creation and transfer of knowledge that drives national competitiveness in an increasingly global era. Its most effective form is the American adaptation of the European model, in which teaching, leaning and research are integrated into a single institution. Indeed, the American university has proved capable of almost anything, from developing advanced economic theories to creating new life forms.
Many national leaders understand that the university is the critical catalyst for America’s adaptability, economic robustness and emergence as a great power. And they are moving aggressively to catch up. The universities created by emerging economies beginning in the 1990s and through 2020 will likely play a decisive role in reshaping the global balance of economic power.
That is bad news for the United States. The past two decades of American university development have been characterized largely by self-satisfaction arising fr
A. is a perfect system which can deal with everything.
B. is a system which is developing rapidly.

[简答题]
(46) For centuries the smoking of tobacco in cigarettes, cigars, and pipes has produced controversy over possible health hazards, but only since the 1950’s has sufficient scientific evidence accumulated to make possible a thorough evaluation of the health risk.
Scientific investigation of the relationship of smoking and health gained impetus after the beginning of the 20th century, then an increase in lung cancer was noted. As the use of tobacco increased, studies improved. (47) Although some gaps in knowledge still exist, the information now available is sufficient to permit making sound judgments, based on the converging lines of evidence.
(48) Investigators have directed their principal consideration to cigarette smoking because the health consequences attributed to it far exceed those due to smoking cigars and pipes. The widespread popularity of cigarettes is comparatively recent in man’s use of tobacco. The smoking -

[单项选择]When stars like our Sun die, they bloat to become red giants and then eject gigantic clouds of gas and dust into space. Increasingly, however, scientists found themselves at a profound loss to explain how exactly dying stars could blow away these clouds. Now astrophysicists propose that unexpected chemical reactions during the formation of stardust could help solve this mystery.
Stars smaller than the Sun and up to eight times as massive die by swelling up into red giants before shedding most of their mass to shrink into very compact, dying embers (灰烬) called white dwarfs. Two kinds of red giants exist-those with lots of carbon, and others richer in oxygen than in carbon. Carbon-rich stars release carbon particles during their death throes. Scientists proposed these pitch-black grains absorb rays from the dying star and get shot into space by starlight, a theory that fit both the observations and computer models.
Increasingly, however, researchers could not explain how oxygen
A. explain-the possible way of death of our Sun.
B. show the two types of red giants.
C. discuss on the way of red giants to become white dwarfs.
D. explore the origin of life.

[单项选择]New graduates in America are used to facing an uncertain future while saddled with heavy debts. Now Sallie Mae, the firm that provides many of them with the financial wherewithal to complete their education, will understand how they feel. On Monday April 16th it was announced that two private-equity firms along with two banks, JPMorgan Chase and Bank of America, had agreed to pay $25 billion for America’s leading student-loan provider.
In the past decade the market for student loans has doubled to around $85 billion a year. Student numbers have swelled while incomes have failed to keep pace with the soaring cost of college education. Sallie Mae has over a quarter of the entire business in America. And though margins are wafer-thin the firm made a profit of $1.2 billion last year.
This profitability has attracted the interest of both Democratic and Republican lawmakers, seeking ways to save money while making education more affordable. Particularly vulnerable is the proportion
A. express the current situation of student-loan.
B. describe the banking industry of the U.S.
C. show problems in politics.
