Why does the Foundation concentrate its support on basic rather than applied research？ Bas

ic research is the very heart of science, and its cumulative product is the capital of scientific progress, a capital that must be constantly increased as the demands upon it rise. The goal of basic research is understanding, for its own sake. Understanding of the structure of the atom or the nerve ceil, the explosion of a spiral nebula or the distribution of cosmic dust, the causes of earthquakes and droughts, or of man as a behaving creature and of the social forces that are created whenever two or more human beings come into contact with one another--the scope is staggering, but the commitment to truth is the same. If the commitment were to a particular result, conflicting evidence might be Overlooked or, with the best will in the world, simply not appreciated. Moreover, the practical applications of basic research frequently cannot be anticipated. When Roentgen, the physicist, discovered X-rays, he had no idea of their usefulness to medicine.

Applied research, undertaken to solve specific practical problems, has an immediate attractiveness because the results can be seen and enjoyed. For practical reasons, the sums spent on applied research in any country always far exceed those for basic research, and the proportions are more unequal in the less developed countries. Leaving aside the funds devoted to research by industry--which is naturally far more concerned with applied aspects because these increase profits quickly--the funds the U.S. Government allots to basic research currently amount to about 7 percent of its overall research and development funds. Unless adequate safeguards are provided, applied research invariably tends to drive out basic. Then, as Dr. Waterman has pointed out, "Developments will inevitably be undertaken prematurely, career incentives will gravitate strongly toward applied science, and the opportunities for making major scientific discoveries will be lost. Unfortunately, pressures to emphasize new developments, without corresponding emphasis upon pure science tend to degrade the quality of the nation% technology in the long run, rather than to improve it."

The title below that best expresses the ideas of this passage is ______.

A．Roentgen's Ignorance of X-rays

B．The Attractiveness of Applied Research

C．The Importance of Basic Research

D．Basic Research vs. Applied Research

The liberal view of democratic citizenship that developed in the 17th and 18th centuries w

as fundamentally different from that of the classical Greeks. The pursuit of private interests with as little interference as possible from government was seen as the road to human happiness and progress rather than the public obligations and involvement in the collective community that were emphasized by the Greeks. Freedom was to be realized by limiting the scope of governmental activity and political obligation and not through immersion in the collective life of the polis. The basic role of the citizen was to select governmental leaders and keep the powers and scope of public authority in check. On the liberal view, the. rights of citizens against the state were the focus of special emphasis.

Over time, the liberal democratic notion of citizenship developed in two directions. First, there was a movement to increase the proportion of members of society who were eligible to participate as citizens--especially through extending the right of suffrage--and to ensure the basic political equality of all. Second, there was a broadening of the legitimate activities of government and a use of governmental power to redress imbalances in social and economic life. Political citizenship became an instrument through which groups and classes with sufficient numbers of votes could use the state power to enhance their social and economic well-being.

Within the general liberal view of democratic citizenship, tensions have developed over the degree to which government can and should be used as an instrument for promoting happiness and well-being. Political philosopher Martin Diamond has categorized two views of democracy as follows. On the one hand, there is the "libertarian" perspective that stresses the private pursuit of happiness and emphasizes the necessity for restraint on government and protection of individual liberties. On the other hand, there is the "majoritarian" view that emphasizes the "task of the government to uplift and aid the common man against the malefactors of great wealth." The tensions between these two views are very evident today. Taxpayer revolts and calls for smaller government and less government regulation clash with demands for greater government involvement in the economic marketplace and the social sphere.

The author's primary purpose is to ______.

A．study ancient concepts of citizenship

B．contrast different notions of citizenship

C．criticize modern libertarian democracy

D．describe the importance of universal suffrage

An owl(猫头鹰) is a bird. There are two basic types of owls: typical owls and barn owls. Owls live in almost every country of the world.

Owls are mostly nocturnal, meaning they are awake at night. Owls are predators——they hunt the food that they eat. Owls hunt for mice and other small mammals, insects, and even fish. Owls are well adapted for hunting. Their soft feathers make their flight nearly silent. They have very good hearing, which helps them to hunt well in the darkness. The sharp hooked beaks and claws of the owl make it very easy to tear apart prey quickly, although owls also eat some prey whole.

Owl eyes are unusual. Like most predators, both of the owl's eyes face front. The owl cannot move its eyes. Owls are far-sighted, which means they can see very well far away, but they can't see up close very well at all. Fortunately, their distant vision is what they use for hunting, and they can see far away even in low light.

Owl can turn their heads 180 degrees. This makes it look like they might be able to turn their heads all the way around, but 180 degrees is all the owl needs to see what's going on all around him.

(66) Perhaps because of the owl's mysterious appearance, especially its round eyes and flexible neck, there are a lot of myths and superstitions (迷信) about owls. Many cultures believe that owls are unusually wise. Because owls are nocturnal, some cultures associate owls with bad omens. However, owls probably do not interact with the fates of humans at all. In fact, some owl species may become extinct because of humans.

Which of the following is NOT true about owls？

A．Owls eat small animals.

B．Owls are able to fly silently.

C．Owls have very poor vision.

D．Owls have flexible necks.
