填空题In the late 1960's many people in North America turned their attention to environmental problems, and new steel-and-glass skyscrapers were widely criticized. 41) __________. Skyscrapers are also lavish comsumers, and wasters of electric power. In one recent year, the addition of 17 million square feet of skyscraper office space in New York City raised the peak daily demand for electricity by 120 000 kilowatts—enough to supply the entire city of Albany, New York, for a day. 42) __________. The heat loss(or gain) through a wall of half-inch plate glass is more than ten times that through a typical masonry wall filled with insulation board. To lessen the strain on heating and air-conditioning equipment, builders of skyscrapers have begun to use double glazed panels of glass, and reflective glasses coated with silver or gold mirror films that reduce glare as well as heat gain. However, mirror-walled skyscrapers raise the temperature of the surrounding air and affect neighboring buildings. 43) __________. If fully occupied, the two World Trade Center towers in New York City would alone generate 2.25 million gallons of raw sewage each year—as much as a city the size of Stanford, Connecticut, which has a population of more than 109000. Skyscrapers also interfere with television reception, block bird flyways, and obstruct air traffic. 44) __________. 45) __________.[A] Glass-walled skyscrapers can be especially wasteful.[B] Tall buildings are an inevitable building form and part of the contemporary landscape.[C] In Boston in the late 1960's, some people even feared that shadows from skyscrapers would kill the grass on Boston Common.[D] Skyscrapers put a severe strain on a city's sanitation facilities, too.[E] Still, people continue to build skyscrapers for all the reasons that they have always built them—personal ambition, civic pride, and the desire of owners to have the largest possible amount of rentable space.[F] Some of these ideas may soon appear in the city as a more holistic approach is taken in balancing environmental and social factors with the economics of building development.[G] Ecologists pointed out that a cluster of tall buildings in a city often overburdens public transportation and parking lot capacities.

填空题Translate From English to Chinese．(中国传媒大学2012研，考试科目：基础英语)On this day, we gather because we have chosen hope over fear, unity of purpose over conflict and discord. On this day, we come to proclaim an end to the petty grievances and false promises, the recriminations and worn out dogmas, that for far too long have strangled our politics.We remain a young nation, but in the words of Scripture, the time has come to set aside childish things. The time has come to reaffirm our enduring spirit: to choose our better history: to carry forward that precious gift, that noble idea, passed on from generation to generation: the God-given promise that all are equal, all are free, and all deserve a chance to pursue their full measure of happiness.In reaffirming the greatness of our nation, we understand that greatness is never a given. It must be earned. Our journey has never been one of short-cuts or settling for less. It has not been the path for the faint-hearted—for those who prefer leisure over work, or seek only the pleasures of riches and fame. Rather, it has been the risk-takers, the doers, the makers of things—some celebrated but more often men and women obscure in their labor, who have carried us up the long, rugged path towards prosperity and freedom.For us, they packed up their few worldly possessions and traveled across oceans in search of a new life. For us, they toiled in sweatshops and settled the west: endured the lash of the whip and plowed the hard earth. For us, they fought and died, in places like Concord and Gettysburg: Normandy and Khe Sahn.

填空题A. They who know nothing listen more B. Women support is essential C. Women who create pink-collar industry D. Women: backbone for e-commerce E. Men: pretended fashion experts F. Men: technology savvy in fashion business G. New form of gender equality 1 According to a 2010 report from comScore, women spend more time online than men, and they"re overrepresented in social networking, gaming, photos, blogs, and retail. Not only do women spend time online, they spend money, too—female customers make up 61% of online transactions. In a TechCrunch article on the topic, Silicon Valley venture capitalist Arleen Lee called women the "rocket fuel" of e-commerce. "Especially when it comes to social and shopping," Lee explains, "women rule the Internet." 2 Hence the surge in "pink-collar" start-ups—businesses in traditionally feminine industries like fashion, beauty, and shopping. But women aren"t the only tech entrepreneurs with their eyes on female customers. From the men behind Pinterest to the dudes who started Shoe Dazzle, smart men are defying gender stereotypes in the pursuit of great business and jumping at the chance to cash in on pink-collar opportunities. Nils Johnson is one of the three male co-founders of Beautylish, a beauty-focused social network. What attracted three men to the female-dominated cosmetics industry? "Most engineers are guys, so they think about products for guys," Johnson explains. "When we thought about the intersection of technology and beauty, we saw a large opportunity in a market that was significantly underserved." Josh Berman and Diego Berdakin are another great example: The duo took their expertise in technology and proximity to the heart of Hollywood and identified a huge opportunity to revolutionize e-commerce. The result was Beachmint, a designer-curated social-commerce site, which catered exclusively to women." The founders never pretended to be fashion experts," says Ara Katz, Beachmint"s Head of Creative and Partnerships. "Their strengths are in technology and operations." 3 When I asked Johnson whether he and his founders had ever encountered criticism, he groaned. "Totally. It"s reverse discrimination. They say, "Why don"t you address something that scratches your own itch?"" But Johnson adds, "I made it clear that I was going to hire the best people." In many cases, that hiring philosophy means actively seeking to hire women, and some male founders are making strategic choices to recruit women to join their founding teams. Of course, these male entrepreneurs make it clear that their co-founders aren"t just window dressing. In addition to their personal knowledge of the female market, women have brought valuable skills to their ventures. 4 These pink-collar male entrepreneurs aren"t letting gender hold them back. In fact, they even see some benefits of their outsider perspective. "It can be hard for entrepreneurs to not think their personal experiences are a proxy for the market," explained Topolovac. "Because I come to the table without emotional attachment to the answers, it"s made me a better listener." 5 Women are the economic engines of some of the Internet"s hottest markets from e-commerce to social media. It"s no wonder then that savvy entrepreneurs—both men and women—are developing ways to better serve the female market. And as with any growing industry, it takes teams of both genders to truly succeed. Just as we need more women to bring their unique perspective to traditionally male-dominated fields, so too will pink-collar industries benefit from smart, innovative men.
