Abstract art also called nonobjective art, or nonrepresentational art, is painting, sculpture, or graphic art in which the portrayal of things from the visible world plays no part. All art consists largely of elements that can be called abstract—elements of form, color, line, tone, and texture. Prior to the 20th century these abstract elements were employed by artists to describe, illustrate, or reproduce the world of nature and of human civilization—and exposition dominated over expressive function.
Abstract art has its origins in the 19th century. The period characterized by so vast a body of elaborately representational art produced for the sake of illustrating anecdote also produced a number of painters who examined the mechanism of light and visual perception. The period of Romanticism had put forward ideas about art that denied classicism’s emphasis on imitation and idealization and had instead stressed the role of imagination and of the unconscious as the essential creative factors. Gradually many painters of this period began to accept the new freedom and the new responsibilities implied in the coalescence of these attitudes. Maurice Denis’s statement of 1890, "It should be remembered that a picture—before being a war-horse, a nude, or an anecdote of some sort—is essentially a fiat surface covered with colors assembled in a certain order," summarizes the feeling among the Symbolist and Postimpressionist artists of his time.
All the major movements of the first two decades of the 20th century, in some way emphasized the gap between art and natural appearances. There is, however, a deep distinction between abstracting from appearances, even if to the point of unrecognizability, and making works of art out of forms not drawn from the visible world. During the several years preceding World War I, such artists as Robert Delaunay and Vladimir Tatlin turned to fundamentally abstract art. (Kandinsky is generally regarded as having been the first modem artist to paint purely abstract pictures containing no recognizable objects.) The majority of even the progressive artist regarded the abandonment of every degree of representation with disfavor, however. During World War I the emergence of the De Stijl group and of the Dada group further widened the spectrum of abstract art.
Abstract art did not flourish between World Wars I and II. Beset by totalitarian politics and by art movements placing renewed emphasis on imagery, such as Surrealism, it received little notice. But after World War II an energetic American school of abstract painting called Abstract Expressionism emerged and had wide influence. Since the 1950s abstract art has been an accepted and widely practiced approach within European and American painting and sculpture. Abstract art has puzzled and indeed confused many people, but for those who have accepted its non referential language there is no doubt as to its value and achievements.

Passage 1
One thing almost everyone is agreed on,
including Americans, is that they place a very high valuation upon success.
Success does not necessarily mean material rewards, but recognition of
some sort preferably measurable. If the boy turns out to be a preacher (传教)
instead of a businessman, that’s all right. But the bigger his church and
congregation, the more successful he is judged to be.
A good
many things contributed to this accent on success. There was the Puritan (清教)
belief in the virtue of work, both for its own sake and because the rewards it
brought were regarded as signs of God’s love. There was the richness of
opportunity in a land waiting to be settled. There was the lack of a settled
society with fixed ranks and classes, so that a man was certain to rise through
achievement.
There was the determination of the immigrant to
gain in the new world what had been denied to him in the old. And on the part of
his children an urge to throw off the immigrant Onus (负担) by still more success
and still more rise in a fluid, classless society. Brothers did not compete
within the family for the favor of the parents as in Europe, but strove for
success is the outer world, along paths of their own
choosing. |
The immigrants went to America mainly to______.
A:search for what had been denied to them in his own society B:compete with their brother C:get rich D:settle
