单选题{{B}}Passage Three{{/B}} Thousands of gypsies have been trying to emigrate to Canada and Britain. They say they are fleeing persecution(迫害), but most have found they are not welcome in these countries either. Gypsies have never had a home. Europe has experienced enormous upheavals this century. Wars, revolutions, separations and elections have changed the political map of the continent countless times. And with each change, power has shifted, creating new winners and new losers. But for one group -- the gypsies -- change has always meant losing. With each upheaval, the gypsies have been left worse off than they were before. Yet they have survived to become Europe's largest minority. Moreover, they have succeeded in preserving their culture and their way of life in the face of genocide (种族灭绝), political persecution and poverty. In other cases where minorities have survived similar persecutions -- like Jews during World War Ⅱ, or blacks in South Africa -- their cause has received international support. By contrast, the gypsies' success at preserving their culture is not regarded as an achievement at all. Instead, it' s viewed as proof they are both unwilling and unable to change, and therefore irredeemable (不可救药的). Indeed, in 1993, the president of the Slovak Republic attacked their way of life and said steps should be taken to limit the extension of this socially unacceptable and mentally backward population. If such a thing had been said about any other minority, the political protest would have been enormous But, bemuse the Slovak President was referring to gypsies, there were few complaints, except from a few small organizations who try to protect gypsies' rights.

单选题Benjamin Day was only 22 years old when he developed the idea of a newspaper for the masses and launched his New York Sun in 1833, which would profoundly alter journalism by his new approach. Yet, several conditions had to exist before a mass press could come into existence. It was impossible to launch a mass-appeal newspaper without invention of a printing press able to produce extremely cheap newspaper affordable almost to everyone. The second element that led to the growth of the mass newspaper was the increased level of literacy in the population. The then increased emphasis on education led to a concurrent growth of literacy as many people in the middle and lower economic groups acquired reading skills. The trend toward "democratization" of business and politics fostered the creation of a mass audience responsive to a mass press. Having seen.others fail in their attempts to market a mass-appeal newspaper, he forged ahead with his New York Sun, which would be a daily and sell for a penny, as compared to the other dailies that went for six cents a copy. Local happenings, sex, violence, features, and human- interest stories would constitute his content. Conspicuously absent were the dull political debates that still characterized many of the six-cent papers. Within six months the Sun achieved a circulation of approximately 8000 issues, far ahead of its nearest competitor. Day's gamble had paid off, and the penny press was launched. James Gordon Bennett, perhaps the most significant and certainly the most colorful of the individuals imitating Day's paper, launched his New York Herald in 1835, even more of a rapid success than the Sun. Part of Bennett's success can be attributed to his skillful reporting of crime news, the institution of a financial page, sports reporting, and an aggressive editorial policy. He looked upon himself a reformer, and wrote in one of his editorials: "I go for a general reformation of morals... I mean to begin a new movement in the progress of civilization." Horace Greeley was another important pioneer of the era. He launched his New York Tribune in 1841 and would rank third behind the Sun and Herald in daily circulation, but his weekly edition was circulated nationally and proved to be a great success. Greeley's Tribune was not as sensational as its competitors. He used his editorial page for crusades and causes. He opposed capital punishment, alcohol, gambling and tobacco. Greeley also favored women's rights. Greeley never talked down to the mass audience and attracted his readers by appealing to their intellect more than to their emotions. The last of the major newspapers of the penny-press era began in 1851. The New York Times, edited by Henry Raymond, promised to be less sensational than the Sun or the Herald and less impassioned than Greeley. The paper soon established a reputation for objective and reasoned journalism. Raymond stressed the gathering of foreign news and served as foreign correspondent himself in 1859. The Times circulation reached more than 40000 before the Civil
