单选题Plastic is the panacea of the ages. Nearly every man-made object (1) (2) of, or at least (3) its very structure, to this wonder compound. Rain slickers, computer terminals, automobile engine parts, coffee cups (and the sugar stirrers too), breast implants, toy soldiers--they are all made up of plastic, or one of its many (4) . Since the (5) of civilization, humankind has been experimenting (6) a multifunctional material--one that had to be equally strong and lightweight--to carry, contain and protect valuables. (7) it could carry, contain and protect humans too, even Better. Generations of tinkerers and scientists set off (8) the challenge, striking gold some 170 years ago. By mixing natural rubber with sulphur they created the world's most utilized material ever. In developing a (9) , malleable and durable substance, the most important inventions of the industrial age were to follow shortly thereafter. The automobile and airplane industries, to (10) just two, owe their very existence to plastic. And, (11) celluloid plastic strips, the Lumiere Brothers would never have brought moving pictures to the big screen. The development of plastic is a story of human (12) , ingenuity and luck. (13) the legend now goes, in 1839, the American inventor Charles Goodyear (the famous tyre company would later use his name) was experimenting with the sulphur treatment of natural rubber when he dropped a piece of sulphur treated rubber on a stove; The heat seemed to give rubber (14) properties. It was stronger, more (15) to abrasion, more elastic, much less (16) to temperature, (17) to gases, and highly resistant to chemicals and electric (18) . Eyeing this as a cheaply and easily reproduced construction material, a whirlwind of work (19) and the birth of (20) plastic and plastic-derivatives were born from camphor to celluloid to rayon; cellophane, polyvinyl chloride (or PVC); styrofoam and nylon were soon to follow.

单选题{{B}}Text 3{{/B}} The mythology of a culture can provide some vital insights into the beliefs and values of that culture. By using fantastic and sometimes incredible stories to create an oral tradition by which to explain the wonders of the natural world and teach lessons to younger generations, a society exposes those ideas and concepts held most important. Just as important as the final lesson to be gathered from the stories, however, are the characters and the roles they play in conveying that message. Perhaps the epitome of mythology and its use as a tool to pass on cultural values can be found in Aesop's Fables, told and retold during the era of the Greek Empire. Aesop, a slave who won the favor of the court through his imaginative and descriptive tales, almost exclusively used animals to fill the roles in his short stories. Humans, when at all present, almost always played the part of bumbling fools struggling to learn the lesson being presented. This choice of characterization allows us to see that the Greeks placed wisdom on a level slightly beyond humans, implying that deep wisdom and understanding is a universal quality sought by, rather than steanning from, human beings. Aesop's fables illustrated the central themes of humility and self-reliance, reflecting the importance of those traits in early Greek society. The folly of humans was used to contrast against the ultimate goal of attaining a higher level of understanding and awareness of truths about nature and humanity. For example, one notable fable features a fox repeatedly trying to reach a bunch of grapes on a very high vine. After failing at several attempts, the fox gives up, making up its mind that the grapes were probably sour anyway. The fable's lesson, that we often play down that which we can't achieve so as to make ourselves feel better, teaches the reader or listener in an entertaining way about one of the weaknesses of the human psyche. The mythology of other cultures and societies reveal the underlying traits of their respective cultures just as Aesop's fables did. The stories of Roman gods, Aztec ghosts and European elves all served to train ancient generations those lessons considered most important to their community, and today they offer a powerful looking glass by which to evaluate and consider the contextual environment in which those culture existed.

单选题Raymond Arth knows he should feel better about the economy. His company hasn't returned to its pre-recession revenues selling its wares to the makers of RVs and manufactured homes, but it is making a profit again. Like too many other small-business proprietors, Arth doesn't fully trust this economic recovery. While he says he's "guardedly optimistic" about it, his actions are all about the first half of that phrase, In the Labor Department's latest snapshot of the country's job market, the private sector added 268,000 jobs in April, the largest gain in five years and the third consecutive month of solid job growth. Yet a more sobering account of where the economy might be headed—and arguably a more accurate barometer of the near-term future—is the monthly report published by the National Federation of Independent Business. After all, it's small businesses, which have created two out of every three new jobs the economy has added since the early 1990s, that historically have led the country out of recessions. And it's the owners of small businesses that the NFIB surveys each month for its Small Business Optimism Index. On that front the news is anything but good. The index is down for the second straight month. Fewer small-business owners expect conditions to improve over the next half year a drop of 18 percentage points from January. The bulk of new hiring must be happening inside larger corporations, since their smaller counterparts on Main Street say they are generally reluctant to create new jobs. That aptly sums up the sentiments of Scott Lipps, the president of the Sleep Tite Mattress Factory. Before the downturn, Lipps says, his sales were about evenly split between his medical clients (hospitals and nursing homes) and consumers buying mattresses through a factory outlet. But sales to the general public plummeted starting in 2008. "The families affected most by the economy have stopped buying," Lipps says. "And those who say 'We have to have a new mattress' are downgrading to a medium-quality mattress. " Despite a 20 percent drop in sales, Lipps and his partner tried to forestall the inevitable by putting up $ 70,000 of their own money. But in 2010 they laid off three of their 18 full-time employees. "It should have happened in 2009, but we let our hearts run the company instead of our billfolds," Lipps says. In Bartlesville, Mat Saddoris is feeling relatively more upbeat. Saddoris is the third-generation owner of United Linen, a restaurant-supply company that cut its workforce by more than 10 percent during the downturn's darkest days. Revenues are back up to pre-2008 levels, and United Linen is back to its pre-recession staffing of 135 employees. But will he take the risk of growing the company? "I talk to my customers and they're optimistic—to a point," he says. "They've all come back from the pits, if you will, and things have been getting better in the past six or seven months. " But, he says, "I don't think they're ready to announce that things have turned around. /
