第2题

Aborigines were earliest known inhabitants of a country. The term is generally applied to the original or native inhabitants of a country, as opposed to a race from another area or colonists and their descendants. Most nations have instituted measures for the welfare of the aborigines within their territories. Such measures include those of the U.S. and Canada concerning Indians and Inuits and those of Australia concerning its aboriginal groups.

All aboriginal peoples have been affected by contact with contemporary civilization; in some cases, the introduction of disease, warfare, alcohol, and drugs has demoralized and destroyed peoples. Others, such as the Ainu of northern Japan, have become almost wholly assimilated. The greatest degree of racial mixture has occurred among the native Polynesians of Hawaii. The Indian population of the U.S. has extensively intermarried with whites; those Indians living on reservations retain some traditional Indian folkways. In Central and South America and in the Caribbean region, many tribes have become extinct, in most cases after Spanish or Portuguese conquest. Among aborigines who have kept strong elements of their original identity are the Inuit, Maori, Dayak, and Australian aborigines. Tribes in such comparatively inaccessible areas as the Amazon River Basin of South America still live largely according to their traditional cultures.

The word "aborigines" most probably means ______.

A.strong colonists.

B.local inhabitants.

C.poor farmers.

D.native people.

Extraordinary creative activity has been characterized as revolutionary, flying in the face of what is established and producing not what is acceptable but what will become accepted. According to this formulation, highly creative activity transcends the limits of an existing form. and establishes a new principle of organization. However, the idea that extraordinary creativity transcends established limits is misleading when it is applied to the arts, even though it may be valid for the sciences.

Differences between highly creative art and highly creative science arise in part from differences in their goals. For the sciences, a new theory is the goal and end result of the creative act. Innovative science produces new propositions in terms of which diverse phenomena can be related to one another in more coherent ways. Such phenomena as a brilliant diamond or a nesting bird are relegated to the role of data, serving as the means for formulating or testing a new theory. The goal of highly creative art is very different: the phenomenon itself becomes the direct product of the creative act. Shakespeare's Hamlet is not a tract about the behavior. of indecisive princes or the uses of political power, nor is Picasso's painting Guernica primarily a prepositional statement about the Spanish Civil War or the evils of fascism. What highly creative artistic activity produces is not a new generalization that transcends established limits, but rather an aesthetic particular. Aesthetic particulars produced by the highly creative artist extend or exploit, in an innovative way, the limits of an existing form, rather than transcend that form.

This is not to deny that a highly creative artist sometimes establishes a new principle of organization in the history of an artistic field: the composer Monteverdi, who created music of the highest aesthetic value, comes to mind. More generally, however, whether or not a composition establishes a new principle in the history of music has little bearing on its aesthetic worth. Because they embody a new principle of organization, some musical works, such as the operas of the Florentine Camerata, are of signal historical importance, but few listeners or musicologists would include these among the great works of music. On the other hand, Mozart's The Marriage of Figaro is surely among the masterpieces of music, even though its modest innovations are confined to extending existing means. It has been said of Beethoven that he toppled the rules and freed music from the stifling confines of convention. But a close study of his compositions reveals that Beethoven overturned no fundamental rules. Rather, he was an incomparable strategist who exploited limits of the rules, forms, and conventions that he inherited from predecessors such as Haydn and Mozart, Handel and Bach in strikingly original ways.

Which of the following is NOT a feature of scientific creativity?

A.Exceeding limits of forms and conventions.

B.Relating diverse phenomena to one another.

C.Forming a new generalization.

D.Discovering a new particular.

第10题

听力原文: When I was at school, my ambition was to be a pilot in the Air Force. But my eyesight wasn't good enough. So I had to give up the idea. I went to university and studied physics. I wanted to stay on there and do research, but my father died at about that time. So I thought I'd better get a job and earn my living. I started working in an engineering firm.

I expected to stay in that job for a long time. But then, they appointed a new managing director. I didn't get on with him, so I resigned and applied for a job at another engineering company. I would certainly have accepted the job if they had offered it to me, but on my way to the interview I met a friend who was working for a travel agency. He offered me a job in Spain. And I've always liked Spain, so I took it.

I worked in the travel agency for two years and then they wanted to send me to South America. But I had just got married. So 1 decided to stay here. Then we had a baby and f wasn't earning enough to support the family. So I started giving English lessons at a school in the evening.

I liked the English teaching more than working for the travel agency, and then the owner of the school offered me a full*time job as a teacher. So I resigned from the agency, Two years later, the owner of the school wanted to retire, so he asked me to take over as the director. And here I am.

(37)

A.He didn't like physics any more.

B.His eyesight was too poor.

C.Physics was too hard for him.

D.He had to work to work to support himself.
