单选题The long years of food shortage in this country have suddenly given way to apparent abundance. Stores and shops are choked with food. Rationing is virtually suspended, and overseas suppliers have been asked to hold back deliveries. Yet, instead of joy, there is widespread uneasiness and confusion. Why do food prices keep on rising, when there seems to be so much more food about? Is the abundance only temporary, or has it come to stay? Does it mean that we need to think less now about producing more food at home? No one knows what to expect. The recent growth of export surpluses on the world food market has certainly been unexpectedly great, partly because a strange sequence of two successful grain harvests in North America is now being followed by a third. Most of Britain's overseas suppliers of meat, too, are offering more this year and home production has also raised. But the effect of all this on the food situation in this country has been made worse by simultaneous rise in food prices, due chiefly to the gradual cutting down of government support for food. The shops are over- stocked with food not only because there is more food available but also because people, frightened by high prices, are buying less of it. Moreover, the rise in domestic prices has come at a time when world prices have begun to fall with the result that imported food, with the exception of grain, is often cheaper than the home- produced variety. And now grain prices, too, are falling. Consumers are beginning to ask why they should not be enabled to benefit from this trend. The significance of these developments is not lost on farmers. The older generations have seen it all happen before. Despite the present price and market guarantees, farmers fear they are about to be squeezed between cheap food imports and a shrinking home market. Present production is running at 51 percent above pre-war levels, and the government has called for an expansion to 60 percent by 1956; but repeated ministerial advice is carrying little weight and the expansion program is not working very well.

单选题In the 1920s demand for American farm products fell, as European countries began to recover from World War I and instituted austerity (紧缩) programs to reduce their imports. The result was a sharp drop in farm prices. This period was more disastrous for farmers than earlier times had been, because farmers were no longer self-sufficient. They were paying for machinery, seed, and fertilizer, and they were also buying consumer goods. The prices of the items farmers bought remained constant, while prices they received for their products fell. These developments were made worse by the Great Depression, which began in 1929 and extended throughout the 1939s. In 1929, under President Herbert Hoover, the Federal Farm Board was organized. It established the principle of direct interference with supply and demand, and it represented the first national commitment to provide greater economic stability for farmers. President Hoover's successor attached even more importance to this problem. One of the first measures proposed by President Franklin D. Roosevelt when he took office in 1933 was the Agricultural Adjustment Act, which was subsequently passed by Congress. This law gave the Secretary of Agriculture the power to reduce production through voluntary agreements with farmers who were paid to take their land out of use. A deliberate scarcity of farm products was planned in an effort to raise prices. This law was declared unconstitutional by the Supreme Court on the grounds that general taxes were being collected to pay one special group of people. However, new laws were passed immediately that achieved the same result of resting soil and providing flood-control measures, but which were based on the principle of soil conservation. The Roosevelt Administration believed that rebuilding the nation's soil was in the national interest and was not simply a plan to help farmers at the expense of other citizens. Later the government guaranteed loans to farmers so that they could buy farm machinery, hybrid (杂交) grain, and fertilizers.

单选题The author thinks that an intelligent person knows______.

单选题 We all know that DNA has the ability to identify individuals but, because it is inherited, there are also regions of the DNA strand which can relate an individual to his or her family (immediate and extended), tribal group and even an entire population. Molecular Genealogy (宗谱学) can use this unique identification provided by the genetic markers to link people together into family trees. Pedigrees (家谱) based on such genetic markers can mean a breakthrough for family trees where information is incomplete or missing due to adoption, illegitimacy or lack of records. There are many communities and populations which have lost precious records due to tragic events such as the fire in the Irish courts during Civil War in 1921 or American slaves for whom many records were never kept in the first place. The main objective of the Molecular Genealogy Research Group is to build a database containing over 100,000 DNA samples from individuals all over the world. These individuals will have provided a pedigree chart of at least four generations and a small blood sample. Once the database has enough samples to represent the world genetic make-up, it will eventually help in solving many issues regarding genealogies that could not be done by relying only on traditional written records. Theoretically, any individual will someday be able to trace his or her family origins through this database. In the meantime, as the database is being created, molecular genealogy can already verify possible or suspected relationships between individuals. “For example, if two men sharing the same last name believe that they are related, but no written record proves this relationship, we can verify this possibility by collecting a sample of DNA from both and looking for common markers (in this case we can look primarily at the Y chromosome(染色体)),” explains Ugo A．Perego, a member of the BYU Molecular Genealogy research team.．

单选题In the 1960s the West Coast became an important center for rock music. Los Angeles and Southern California are famous for sunshine and surfing. There, a quieter kind of rock called surf rock became famous. The Beach Boys sang songs like "Surfin' U. S. A.", "California Girls" and "Fun, Fun, Fun". These songs made people dream about the good life in California. San Francisco was a center for young people and rock music in the late 1960s. This was the time of the Vietnam War, student protest, hippies, and drugs. Hippies talked about love and peace. They wore brightly colored clothes and had long hair. They listened to rock and folk-rock music. Drugs were a serious problem during that time. The deaths of three young rock stars, Janis Jopling, Jim Morrison and the great guitar player Jim Hendrix were all related to drugs. Not all of the rock musicians came from California or the U. S. A.. That was the time of the great British rock groups like the Beatles and the Rolling Stones. British rock musicians had a very important place in the rock music of the 1960s in America. Another kind of softer rock music was created by the singers. Singers like Joni Mitchell and James Taylor wrote their own lyrics and their own music. Their songs were about love and friendship, good and bad times. In the 1960s big rock concerts were very welcomed by everyone. The most famous concert was Woodstock. In 1969 in New York State, a million young people came together to hear the rock stars. This peaceful Woodstock concert was the most important musical event of the 1960s. After World War Ⅱ a great number of black people moved from the South to the big industrial cities like New York, Detroit, and Philadelphia. Many black people lived in poor parts of the city such as Harlem in New York. Musicians wrote and sang about life in the big cities. Life was difficult but music and dancing made it a little easier. Popular black music had a strong beat for dancing. At first this music was called rhythm and blues. The 1960s called it soul. In Detroit, a black musician named Berry Gordy set up an all black record company. It was called Motown. Motown or motor town is another name for Detroit, where cars are made. Most of the famous soul musicians like the Supremes, the Temptations, and the Jackson Five recorded with Motown.

单选题In a democratic society citizens are encouraged to form their own opinions on candidates for public offices, taxes, constitutional amendments, environmental concerns, foreign policy, and other issues, The opinions held by any population are shaped and manipulated by several factors: individual circumstances, the mass media, special-interest groups, and opinion leaders. Wealthy people tend to think differently on social issues from poor people. Factory workers probably do not share the same views as white-collar workers, non-union workers. Women employed outside their homes sometimes have perspectives different from those of full-time homemakers. In these and other ways individual status shapes one's view of current events. The mass media, especially television, are powerful influences on the way people think and act. Government officials note how mail from the public tends to "follow the headlines". Whatever is featured in news- papers and magazines and on television attracts enough attention that people begin to inform themselves and to express opinions. The mass media have also created larger audiences for government and a wider range of public issues than existed before. Prior to television and the national editions of newspapers, issues and candidates tended to re- main localized. In Great Britain and West Germany, for example, elections to the national legislatures were usually viewed by voters as local contests. Today's elections are seen as struggles between party leaders and programs In the United States radio and television have been beneficial to the presidency. Since the days of Franklin D. Roosevelt and his "fireside chats", presidents have appealed directly to a national audience over the heads of Congress to advocate their programs. Special-interest groups spend vast sums annually trying to influence public opinion. Public utilities, for instance, tried to sway public opinion in favor of nuclear power plants. Opposed to them were citizens' organizations successful advertising campaign designed to prevent the passage of medicare. Opinion leaders are usually such prominent public figures as politicians, some business personalities, and celebrity athletes. The opinions of these individuals, whether informed and intelligent or not, carry weight with some segments of the population. Some individuals, such as Nobel Prize winners, are suddenly thrust into public view by the media. By quickly reaching a large audience, their views gain a hearing and ere perhaps influential in shaping views on complex issues.

单选题{{B}}Passage 2{{/B}} A rose by any other name may smell as sweet, but if it's not red or yellow, it doesn't sell. According to James Crowe, chief executive of the Worcester -- based research company, Scintilla, the color of a product can dictate the strength of its sales. His company has pioneered a method of testing consumer response to color which he claims can predict, with 90% accuracy, sales of a new product for up to 18 months after the launch. The method, "Chromtest", has been used to test everything from ladies' dresses to sunglasses. Clients include Parsifal Lager, Amir Fashions, Coloroll Wallpaper and Meadowcourt China. Color, says Mr. Crowe, is critical in ensuring product acceptance. It is not merely a case of choosing an acceptable primary color -- shades, tones and texture can all have a bearing on the consumer's final choice. "We could take 10 colors, each with six shades and virtually guarantee that two of the shades would be most popular with 80% of the people interviewed," he said. "Products are associated with lifestyle: most kitchens are now in wood so if you make toasters you don't want a color that is unsuitable." Mr. Crowe, a former lecturer at the Institute of Marketing, formed Scintilla in 1992 with the help of a $ 5,000 second mortgage. First year turnover was $100,000. This year with 30 staff it will be ten times that. Chromtest, which was developed with the help of Crowe's artist wife, Susanne, now accounts for around 70% of turnover and provides most of the profits. Crowe admits that British companies still have their doubts, though he says a few retailers now insist that products are color screened before they are allowed on their shelves. He contrasts this with European manufacturers who commission over half the company's works. European tests do vary dramatically, however, and Crowe argues that, as with branding, color and design for pan-European products carry numerous pitfalls. For example, a recent test of a brown dinner service in Britain, Germany and France shows that while consumers in the first two countries like the product, Parisians will not eat off brown plates.
