单选题Passage One There is substantial evidence that by 1926, with the publication of The Weary Blues, Langston Hughes had broken with two well-established traditions in African American literature. In The Weary Blues, Hughes chose to modify the traditions that decreed that African American literature must promote racial acceptance and integration, and that, in order to do so, it must reflect an understanding and mastery of Western European literary techniques and styles. Necessarily excluded by this decree, linguistically and thematically, was the vast amount of secular folk material in the oral tradition that had been created by Black people in the years of slavery and after. It might be pointed out that even the spirituals or "sorrow songs" of the slaves-as distinct from their secular songs and stories-had been Europeanized to make them acceptable within these African American traditions after the Civil War. In 1862 northern White writers had commented favorably on the unique and provocative melodies of these "sorrow songs" when they first heard them sung by slaves in the Carolina sea islands. But by 1916, ten years before the publication of The Weary Blues, Hurry T. Burleigh, the Black baritone soloist at New York's ultrafashionable Saint George's Episcopal Church, had published Jubilee Songs of the United States, with every spiritual arranged so that a concert singer could sing it "in the manner of an art song." Clearly, the artistic work of Black people could be used to promote racial acceptance and integration only on the condition that it became Europeanize. Even more than his rebellion against this restrictive tradition in African American art, Hughes's expression of the vibrant folk culture of Black people established his writing as a landmark in the history of African American literature. Most of his folk poems have the distinctive marks of this folk culture's oral tradition : they contain many instances of naming and enumeration, considerable hyperbole and understatement, and a strong infusion of street-talk rhyming. There is a deceptive veil of artlessness in these poems. Hughes prided himself on being an impromptu and impressionistic writer of poetry. His, he insisted, was not an artfully constructed poetry. Yet an analysis of his dramatic monologues and other poems reveals that his poetry was carefully and artfully crafte. In his folk poetry we find features common to all folk literature, such as dramatic ellipsis, narrative compression, rhythmic repetition, and monosyllabic emphasis. The peculiar mixture of irony and humor we find in his writing is a distinguishing feature of his folk poetry. Together, these aspects, of Hughes's writing helped to modify the previous restrictions on the techniques and subject matter of Black writers and consequently to broaden the linguistic and thematic range of African American literature.

单选题At first glance the patriarchy appears to be thriving. More than 90% of presidents and prime ministers are male, as are nearly all big corporate bosses. Men dominate finance, technology, films, sports, music and even stand-up comedy. In much of the world they still enjoy social and legal privileges simply because they have a Y chromosome. So it might seem odd to worry about the plight of men. Yet there is plenty of cause for concern. Men cluster at the bottom as well as the top. They are far more likely than women to be jailed, estranged from their children, or to kill themselves. They earn fewer university degrees than women. Boys in the developed world are 50% more likely to flunk basic maths, reading and science entirely. One group in particular is suffering. Poorly educated men in rich countries have had difficulty coping with the enormous changes in the labor market and the home over the past half-century. As technology and trade have devalued brawn, less-educated men have struggled to find a role in the workplace. Women, on the other hand, are surging into expanding sectors such as health care and education, helped by their superior skills. As education has become more important, boys have also fallen behind girls in school (except at the very top ) . Men who lose jobs in manufacturing often never work again. And men without work find it hard to attract a permanent mate. The result, for low-skilled men, is a poisonous combination of no job, no family and no prospects. Those on the political left tend to focus on economics. Shrinking job opportunities for men, they say, are entrenching poverty and destroying families. In America pay for men with only a high-school certificate fell by 21% in real terms between 1979 and 2013; for women with similar qualifications it rose by 3%. Around a fifth of working-age American men with only a high-school diploma have no job. Those on the right worry about the collapse of the family. The vast majority of women would prefer to have a partner who does his bit both financially and domestically. But they would rather do without one than team up with a layabout, which may be all that is on offer: American men without jobs spend only half as much time on housework and caring for others as do women in the same situation, and much more time watching television. Hence the unravelling of working-class families. The two-parent family, still the norm among the elite, is vanishing among the poor. In rich countries the proportion of births outside marriage has trebled since 1980, to 33%. In some areas where traditional manufacturing has collapsed, it has reached 70% or more. Children raised in broken homes learn less at school, are more likely to drop out and earn less later on than children from intact ones. They are also not very good at forming stable families of their own. These two sides often talk past each other. But their explanations are not contradictory: both economics and social change are to blame, and the two causes reinforce each other. Moreover, these problems are likely to get worse. Technology will disrupt more industries, creating benefits for society but rendering workers who fail to update their skills redundant. The OECD, a think-tank, predicts that the absolute number of single-parent households will continue to rise in nearly all rich countries. Boys who grow up without fathers are more likely to have trouble forming lasting relationships, creating a cycle of male dysfunction.
