T

    40、his growing interestcoincided with two developments in Negrolife that fostered the growth of the New(15) Negro Movement.

    44、 and radical movements that arenow seizing the reins of power in all the civi-lized countries of the world.“ Such forcesmay have produced the New Negro, but the(45) more articulate of the group did not resortto advocating the type of political action thatwould have subverted American constitu-tional

    45、 government. Indeed, the writers of theHarlem Renaissance were not so much(50) revolting against the system as they wereprotesting its inefficient operation. In thisapproach they proved as characteristicallyAmerican as any writers of the period.(分数:5.00)(1).Which of the following is implied by the s

    47、on efficiently.C. Black writers in general were not opposed to the system as such.D. In order for the system to operate efficiently, blacks must seize the reins of power in America.E.
