单选题The 47-year-old politician rose to the highest post because of his stand against the war in Iraq and his plans to fix a weak economy. But what will the first 47-year-old African- American president do for race relations? Obama's victory appears to have given blacks and other minorities a true national role model. For years, many looked to athletes and musicians for inspiration. As Darius Turner, an African-American high school student in Los Angeles, told The Los Angeles Times, "Kobe doesn't have to be everybody's role model any more." Recent polls also suggest that Obama's victory has given Americans new optimism about race relations. For example, a USA Today poll found that two-thirds of Americans believe relations between blacks and whites "will finally be worked out". This is the most hopeful response since the question was first asked during the civil rights revolution in 1963. However, it's still too early to tell whether Obama's presidency will begin to solve many of the social problems facing low-income black communities. Although blacks make up only 13 percent of the US population, 55 percent of all prisoners are African-American. Such numbers can be blamed on any number of factors on America's racist past, a failure of government policy and the collapse of the family unit in black communities. It is unlikely that Obama will be able to reverse such trends overnight. However, Bill Bank, an expert of African-American Studies, says that eventually young blacks need to find role models in their own communities. "That's not Martin Luther King, and not Barack Obama," he told The Los Angeles Times. "It's actually the people closest to them. Barrack only has so much influence." In the opinion of black British politician Trevor Phillips, Obama's rise will contribute more to multiculturalism than to race relations in the US. "When the G8 meets, the four most important people in the room will be the president of China, the prime minister of India, the prime minister of Japan and Barrack Obama," he told London's The Times newspaper. "It will be the first time we've seen that on our television screens. That will be a huge psychological shift(心理转变) for both the white people and the colored ones in the world./

单选题Some surveys show that a lot of people believe that the glare from snow causes snow-blindness. Yet, wearing dark glasses or not, they find themselves suffering from headaches and watering eyes, and even snow-blindness, when exposed to several hours of "snow light". The United States Army has now determined that glare from snow actually does not cause snow-blindness in troops in snow-covered country. Rather, a man's eyes frequently find nothing to focus on in a broad expanse of a wide snow-covered territory. His gaze, in consequence, continually shifts and jumps back and forth over the entire landscape in search of something he can look at. Finding nothing to focus on, hour after hour, the eyes never stop searching, and the eyeballs will become sore and eye muscles will ache. Nature reduces this uncomfortable feeling by producing more and more fluid which covers the eyeball. The fluid covers the eyeball in increasing quantity until vision becomes increasingly unclear. The result may be total, even though temporary, snow-blindness. Experiments led the Army to a simple method of overcoming this problem. A small group of soldiers will be sent ahead of a main body of troops. They are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape. Even these soldiers themselves throw lightweight, dark colored objects ahead, on which they, too, can focus. The men following them can then see something. Their gaze is arrested. Their eyes focus on a bush and, having found something to see, stop searching the snow-blanketed landscape. By focusing their attention on lone object at a time, the troops can cross the snow-covered wilderness without becoming hopelessly snow-blind or lost. In this way the problem of crossing a solid white territory is overcome.
