33、age.The Quechua world is submerged, so tospeak, in a cosmic magma that weighs heav-ily upon it. It possesses the rare quality ofLine being as it were interjected into the midst of(5) antagonistic forces, which in turn implies awhole body of social and aesthetic structureswhose innermost meaning must

34、 be theadministration of energy. This gives rise tothe social organism known as the ayllu, the(10) agrarian community that regulates the pro-curement of food. The ayllu formed the basicstructure of the whole Inca empire.The central idea of this organization was akind of closed economy, just the oppo

35、site of(15) our economic practices, which can bedescribed as open. The closed economyrested on the fact that the Inca controlledboth the production and consumption offood. When one adds to this fact the reli-(20) gious ideas noted in the Quechua texts citedby the chronicler Santa Cruz Pachacuti, one

36、comes to the conclusion that in the Andeanzone the margin of life was minimal andwas made possible only by the system of(25) magic the Quechua constructed throughhis religion.Adversities, moreover, were numerous,for the harvest might fail at any time andbring starvation to millions.

37、ole purpose of the Quechua administra-tive and ideological system was to carry onthe arduous task of achieving abundance andstaving off shortages.

39、rld was also vanquished.(45) These considerations permit us to classifyQuechua culture as absolutely static or, moreaccurately, as the expression of a mere stateof being. Only in this way can we under-stand the refuge that it took in the germina-(50) tive center of the cosmic mandala as revealedby Q

40、uechua art. The Quechua empire wasnothing more than a mandala, for it wasdivided into four zones, with Cuzco in thecenter. Here the Quechua ensconced himself(55) to contemplate the decline of the world asthough it were caused by an alien andautonomous force.（分数：5.00）(1).The term “mandala“ as used in

Modern Western society should adopt some Quechua economic ideas.（分数：1.00）A.B.C.D.E.(4).On October 3, 1965, President Lyndon B. Johnson signed a law that sought to overturn four decades of discrimina

44、tion. The National Origins Quota System, which had been in effect since 1924, determined which immigrants should be allowed to come to the United States based solely on their national origin. The 1965 Immigration Act changed all this by making individual work skills and relationships with current U.

45、S. citizens the criteria for immigration. President Johnson captured the essence of this exciting change by declaring that “those who can contribute most to this country-to its growth, to its strength, to its spirit-will be the first that are admitted to this land.“ The authors attitude toward the I

48、lways been my goal to have experiences on vacation that most other tourists fail to find. When my plans were finalized, I left for Africa.
