[单项选择]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 hind generally. On the one hand, there is the American commitm
A. many public institutions have to cut down enrollment of students
B. teachers are not qualified enough for satisfactory performance in classes
C. some institutions have to reduce the expenses on research
D. there is competition for resources and attention of faculty between public and private institution

[简答题]But in recent years it has become more and more evident that this pursuit has led to a "brave new world" of consumer goods and services.

[单项选择]In recent years the climate has been generally cool in northern Asia. But during periods when the average daily temperature and humidity in northern Asia were slightly higher than their normal levels the yields of most crops grown there increased significantly. In the next century, the increased average daily temperature and humidity attained during those periods are expected to become the norm. Yet scientists predict that the yearly yields of most of the region’s crops will decrease during the next century.
Which one of the following, if true, most helps to resolve the apparent paradox in the information above
A. Crop yields in southern Asia are expected to remain constant even after the average daily temperature and humidity there increase from recent levels.
B. Any increases in temperature and humidity would be accompanied by higher levels of atmospheric carbon dioxide, which is vital to plant respiration.
C. The climate in northern Asia has generally been too cool and dry in recent years for populations of many crop insect pests to become established.
D. In many parts of Asia, the increased annual precipitation that would result from warmer and wetter climates would cause most edible plant species to flourish.
E. (E) The recent climate of northern Asia prevents many crops from being farmed there during the winter.
