In most North American tribes, men almost exclusively produced artistic compositions that depict life forms and supernatural beings. Wom
22、en, on the other hand, traditionally made abstract, geometric compositions. Among Plains Indians, the abstract designs that were the womens prerogative have survived in greater numbers than those made by men. It seems that the abstract and geometric art is older than the representational art by men.
23、 More importantly, it later evolved and provided designs for weaving, quillwork, and beadwork. These art works are presented in such patterns as circles, arcs, triangles, rectangles, and hyperbolas. The colors are mostly red, yellow, blue and green, and they are painted flat and are outlined. The wo
24、mens geometric art appears on such objects as hide robes, boxes, bags and other utilitarian receptacles. II. The most influential Plains art form was the narrative composition, which is meant to tell heroic stories of courageous deeds. These arts works were often drafted by a group of men, often the
25、 individuals who had performed the deeds being recorded. The paintings, usually filling entire field, were conceived as separate pictorial vignettes recording specific actions. In relationship to each other, these vignettes tell a complete story. Composition was focused on the center of the skin, wh
26、ere the action was depicted and the figures were larger and more numerous. Often the composition is centrifugal, without top or bottom, which suggests that the hide was painted to be shown on the ground surrounded by viewers. 要二氧化碳。(3)根据以上结论可得出增加光照、提高二氧化碳含量等措施，可以提高产量。(4)绿色植物对于维持生物圈中的碳一氧平衡起重要作用。22(1)
