单选题The United Nations Population Fund has picked October 31 as the day the world will be home to 7 billion people. For better and worse, it's a milestone. And there will be more milestones ahead. Fourteen years from now, there are expected to be 8 billion people on the planet. Most of the growth will occur in the world's poorer countries. Proportionally, Europe's population will decline, while Africa's will increase. At around the same time, India will overtake China as the most populous nation on Earth. The growing global population is just one side of the coin. A recent report from the World Health Organization signaled the seriousness of the human population explosion: more than 3 billion people — about half the world's population — are malnourished. Never before have so many, or such a large proportion, of the world's people been malnourished. And in a growing number of countries there is a seemingly unstoppable march toward sub-replacement fertility, whereby each new generation is less populous than the previous one, and population aging. As a result of declining fertility and increasing longevity, the populations of more and more countries are aging raging rapidly. Between 2005 and 2050, a rise in the population aged 60 years or over will be visible, whereas the number of children(persons under age 15)will decline slightly. Population aging represents, in one sense, a success story for mankind, but it also poses profound challenges to public institutions that must adapt to a changing age structure. The latest national census in China shows the number of elderly people in the country has jumped to more than 13. 3 percent of the population, an increase of nearly 3 percentage points on the percentage from the previous census in 2000. A quarter of the country's population will be over 65 by 2050, according to the National Population and Family Planning Commission. The growing number of elderly is a challenge that the government needs to tackle, we can't rely on the ever-increasing population to support them or maintain the nation's economic growth. Better solutions are needed, such as raising retirement ages to reflect the greater longevity and working capability of today's older adults and making adjustments so pension programs are more accessible. It was heartening to hear the Ministry of Human Resources and Social Security spokesperson announced in Beijing on Tuesday that the government will take retirement policy seriously and proactively. Shanghai began testing a flexible retirement system last October. Eligible employees in the private sector are allowed to postpone retirement until the age of 65 for men and 60 for women. Public servants, however, will continue to retire under the present system age 60 for men and 55 for women.

单选题Direct advertising includes all forms of sales appeals, mailed, delivered, or exhibited directly to the prospective buyer of an advertised product or service, without use of any indirect medium, such as newspapers or television. Direct advertising logically may be divided into three broad classifications, namely, direct-mail advertising, mail order advertising, and unmailed direct advertising. All forms of sales appeals that are sent through the mails are considered direct-mall advertising. The chief functions of direct-mail advertising are to familiarize prospective buyers with a product, its name, its maker, and its merits and with the products local distributors. The direct-mall appeal is designed also to support the sales activities of retailers by encouraging the continued patronage of both old and new customers. When no personal selling is involved, other methods are needed to persuade people to send in orders by mail. In addition to newspapers, magazines, radio, and television, other special devices, order promotions are designed to accomplish a complete selling job without salespeople. Used for the same broad purposes as direct-mail advertising, unrolled direct-mail advertising, includes all forms of indoor advertising displays and all printed sales appeals distributed from door to door, handed to customers in retail stores or conveyed in some other manner directly to the recipient. With each medium competing keenly for its share of the business, advertising agencies continue to develop new techniques for displaying and selling wares and services. Among these techniques have been vastly improved printing and reproduction methods in the graphic field, adapted to magazine advertisements and to direct-mail enclosures; the use of color in newspaper advertisements and in television; and outdoor signboards more attractively designed and efficiently lighted. Many subtly effective improvements are suggested by advertising research.

单选题1 The next time the men were taken up onto the deck, Kunta made a point of looking at the man behind him in Mine, the one who May beside him to the left when they were be low. He was a Serer tribesman much older than Kunta, and his body, front and back, was creased with whip cuts, some of them so deep and festering that Kunta, felt badly for having wished sometimes that he might strike the man in the darkness for moaning so steadily in his pain. Staring hack at Kunta, the Serer's dark eyes were full of fury and defi ance. A whip lashed out even as they stood looking at each other this time at Kunta, spurring him to move ahead. Trying to roll away, Kunta was kicked heavily in his ribs. But somehow he and the gasping Wolof managed to stagger back up among the other men from their shelf who were shambling toward their dousing with bucked of seawater. A moment later, the stinging saltiness of it was burning in Kunta's wounds, and his screams joined those of others over the sound of the drum and the wheezing thing that had again begun marking time for the chained men to jump and dance for the toubob. Kunta and the WoMof were so weak from their new beating that twice they stumbled, but whip blows and kicks sent them hopping clumsily up and down in their chains. So great was his fury that Kunta was barely aware of the women singing "Toubob fa!" And when he had finally been chained back down in his place in the dark hold, his heart throbbed with a lust to murder toubob. Every few days the eight naked toubob would again come into the stinking darkness and scrape their tubs full of the excrement that had accumulated on the shelves where the chained men May. Kunta would lie still with his eyes staring balefully in hatred, foMlowing the bobbing orange lights, listening to the toubob cursing and sometimes slipping and tail ing into the slickness underfoot—so plentiful now, because of the increasing looseness of the men's bowels, that the filth had begun to drop off the edges of the shelves down into the aisMeway. The last time they were on deck, Kunta had noticed a man limping on a badly infected leg. This time the man was kept up on deck when the rest were taken back beMow. A few days later, the women told the other prisoners in their singing that the man's leg had been cut off and that one of the women had been brought to tend him, but that the man had died that night and been thrown over the side. Starting then, when the toubob came to clean the shelves, they also dropped red-hot pieces of metal into pails of strong vine gar. The clouds of acrid steam left the hold smelling better, but soon it would again be overwhelmed by the choking stink. It was a smell that Kunta felt would never leave his lungs and skin. The steady murmuring that went on in the hold whenever the toubob were gone kept growing in volume and intensity as the men began to communicate better and better with one another. Words not understood were whispered from mouth to ear along the shelves until someone who knew more than one tongue would send back their meanings. In the process, all of the men along each shelf learned new words in tongues they had not spoken before. Sometimes men jerked upward, bumping their heads, in the double excitement of communicating with each other and the fact that it was being done without the toubob's knowledge. Muttering among themselves for hours, the men developed a deepening sense of intrigue and of brotherhood. Though they were of different villages and tribes, the feel ing grew that they were not from different peoples or places.
