单选题As one of a rare group of economists who believe that "manufacturing matters" for the health of the American economy, I was heartened to hear President Obama emphasize manufacturing in his State of the Union address. During the last two years, the manufacturing sector has led the economic recovery, expanding by about 10 percent and adding more than 300,000 jobs. Though there are economists who do not share my view, I believe that a strong manufacturing sector matters for several reasons. First, economists agree that the United States must rebalance growth away from consumption and imports financed by foreign borrowing toward exports. Manufactured goods account for about 86 percent of merchandise exports from the United States and about 60 percent of exports of goods and services combined. American manufacturing exports are becoming more attractive as a result of rising wages abroad, the decline in the dollar"s value, increasing supply-chain coordination and transportation costs, and strong productivity growth in American manufacturing. Germany and Japan, two high-wage countries, have maintained substantial shares of manufacturing in their economies, and are major exporters of manufactured goods to emerging market economies. Like manufacturing in these countries, manufacturing in the United States can win larger shares of global export markets with the right policies in place. Second, on average manufacturing jobs are high-productivity, high value-added jobs with good pay and benefits. In 2009, the average manufacturing worker earned $74,447 in annual pay and benefits compared with $63,122 for the average non-manufacturing worker. In that year, only about 9 percent of the work force was employed in manufacturing, down from about 13 percent in 2000. The fall in manufacturing employment during the 2000s was a major factor behind growing wage inequality and the polarization of job opportunities between the top and bottom of the wage and skill distribution, with a hollowing out of middle-income jobs. Third, manufacturing matters because of its substantial role in innovation. American leadership in science and technology remains highly dependent on R. & D. investment by manufacturing companies, and the social returns to such investment are substantial, far exceeding the returns to the companies that fund it. American multinational companies that account for about 84 percent of all private-sector business R. & D. in the United States still place about 84 percent of their R. & D. activities in the United States, often in clusters around research universities. But this share is gradually declining as American companies shift some of their R. & D. to Asia in response to rapidly growing markets, ample supplies of technical workers and engineers and generous subsidies. Congress"s failure to extend and broaden the R. & D. tax credit, as President Obama has urged, is also encouraging companies in the United States to look to other countries offering far more generous R. & D. tax incentives.

单选题 Passage Three (1) Viewed from a star in some other corner of the galaxy, Earth would be a speck, a faint blue dot hidden in the blazing light of our sun. While our neighbors Venus and Mars would reflect a fairly even glow. Earth would put on a little show. Earth's light would brighten and dim as it spins, because oceans, deserts, forests and clouds which are all too small to be seen from such a distance, reflect varying amounts of sunlight. The variations, it turns out, are so strong and distinctive that surprising amount of information could be taken from a simple ebb and flow of light. Scientists at Princeton University and the Institute for Advanced Study conducted a detailed study of Earth's reflections as a way for human scientists to learn about distant planets that may be like our own. (2) "If you looked at our solar system from far away, and you looked at the terrestrial planets Mercury, Venus, Earth and Mars, one of the quickest ways to see that Earth is unique, which is by looking at the light curve," said Ed Turner, professor of astrophysics and a co-author of the study. "Earth has by far the most complicated light curve." The standard thinking in the field had been that most of the information about an Earth-like planet would come from spectral analysis, a static reading of the relative component of different colors within the light, rather than a reading of changes over time. Spectral analysis would reveal the presence of gases such as water vapor, carbon dioxide and oxygen, in the planet's atmosphere. Looking at the change in light over time does not replace spectral analysis, but it could greatly increase the amount of information scientists could learn, said Turner. It may indicate, for example, the presence of weather, oceans, ice or even plant life.

单选题{{B}}Passage Three{{/B}} More than 6,000 children were expelled (开除) from US school last year for bringing guns and bombs to school, the US Department of Education said on May 8. The department gave a report to the expulsions (开除) as saying handguns accounted for 58% of the 6,093 expulsions in 1996—1997, against 7% for rifles (步枪) or shotguns and 35% for other types of firearms. "The report is a clear sign that our nation's public schools are cracking down (严惩) on students who bring guns to school," Education Secretary Richard Riley said in a statement. In March 1997, an 11-year old boy and a 13-year old boy using handguns and rifles shot dead four children and a teacher at a school in Arkansas. In October, two were killed and seven wounded in a shooting at a Mississippi school. Two months later, a 14-year old boy killed three high school students and wounded five in Kentucky. Most of the expulsions, 56%, were from high school, 34% were from junior high schools and 9% were from elementary schools, the report said.

单选题{{B}}Text 4{{/B}} In 1784, five years before he became president of the United States, George Washington, 52, was nearly toothless. So he hired a dentist to transplant nine teeth into his jaw—having extracted them from the mouths of his slaves. That's a far different image from the cherry-tree-chopping George most people remember from their history books. But recently, many historians have begun to focus on the roles slavery played in the lives of the founding generation. They have been spurred in part by DNA evidence made available in 1998, which almost certainly proved Thomas Jefferson had fathered at least one child with his slave Sally Hemings. And only over the past 30 years have scholars examined history from the bottom up. Works of several historians reveal the moral compromises made by the nation's early leaders and the fragile nature of the country's infancy. More significantly, they argue that many of the Founding Fathers knew slavery was wrong--and yet most did little to fight it. More than anything, the historians say, the founders were hampered by the culture of their time. While Washington and Jefferson privately expressed distaste for slavery, they also understood that it was part of the political and economic bedrock of the country they helped to create. For one thing, the South could not afford to part with its slaves. Owning slaves was "like having a large bank account," says Wiencek, author of An Imperfect God: George Washington, His Slaves, and the Creation of America. 'The southern states would not have signed the Constitution without protections for the "peculiar institution," including a clause that counted a slave as three fifths of a man for purposes of congressional representation. And the statesmen's political lives depended on slavery. The three-fifths formula handed Jefferson his narrow victory in the presidential election of 1800 by inflating the votes of the southern states in the Electoral College. Once in office, Jefferson extended slavery with the Louisiana Purchase in 1803; the new land was carved into 13 states, including three slave states. Still, Jefferson freed Hemings's children—though not Hemings herself or his approximately 150 other slaves. Washington, who had begun to believe that all men were created equal after observing the bravery of the black soldiers during the Revolutionary War, overcame the strong opposition of his relatives to grant his slaves their freedom in his will. Only a decade earlier, such an act would have required legislative approval in Virginia.
