单选题By the mid-nineteenth century, the term "ice-box" had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States: The ice trade grew with the growth of cities. Ice was used in hotels, taverns, and hospitals, and by some forward-looking city dealers in fresh meat, fresh fish, and butter. After the Civil War (1861-1865), as ice was used to refrigerate freight cars, it also came into household use. Even before 1880, half the ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston and Chicago, went to families for their own use. This had become possible because a new household convenience, the icebox, a precursor of the modern refrigerator, had been invented. Making an efficient icebox was not as easy as we might now suppose: In the early nineteenth century, the knowledge of heat, which was essential to a science of refrigeration, was rudimentary. The commonsense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the delicate balance of insulation and circulation needed for an efficient icebox. But as early as 1803, an ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, for which the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium price for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool.

单选题It"s been called the Gig Economy, Freelance Nation, the Rise of the Creative Class, and the e-economy, with the "e" standing for electronic, entrepreneurial. Everywhere we look, we can see the U.S. workforce undergoing a massive change. No longer do we work at the same company for 25 years, waiting for the gold watch, expecting the benefits and security that come with full-time employment. We"re no longer simply lawyers, or photographers, or writers. Instead, we"re part-time lawyers-cum-amateur photographers who write on the side. Today, careers consist of piecing together various types of work, juggling multiple clients, learning to be marketing and accounting experts, and creating offices in bedrooms/coffee shops. Independent workers abound. We call them freelancers, contractors, sole proprietors, consultants, temps, and the self-employed. This transition is nothing less than a revolution. We haven"t seen a shift in the workforce so significant in almost 100 years since we transitioned from an agricultural to an industrial economy. Now, employees are leaving the traditional workplace and opting to piece together a professional life on their own. As of 2005, one-third of our workforce participated in this "freelance economy". Statistics show that number has only increased over the past six years. While the economy has unwillingly pushed some people into independent work, many have chosen it because of greater flexibility that lets them skip the dreary office environment and focus on more personally fulfilling projects. These trends will have an enormous impact on our economy and our society: We don"t actually know the true composition of the new workforce. After 2005, the government stopped counting independent workers in a meaningful and accurate way. Studies have shown that the independent workforce has grown and changed significantly since then. Jobs no longer provide the protections and security that workers used to expect. The basics such as health insurance, protection from unpaid wages, a retirement plan, and unemployment insurance are out of reach for one-third of working Americans. Independent workers are forced to seek them elsewhere, and if they can"t find or afford them, then they go without. Therefore, it"s time to build a new support system that allows for the flexible and mobile way that people are working. This new, changing workforce needs to build economic security in profoundly new ways. For the new workforce, the New Deal is irrelevant. When it was passed in the 1930s, the New Deal provided workers with important protections and benefits but those securities were built for a traditional employer-employee relationship. The New Deal has not evolved to include independent workers.

单选题 Passage 9 One of the most interesting of all studies is the study of words and word origins. Each language is {{U}}(1) {{/U}} of several earlier languages, and the words of a language can sometimes be traced {{U}}(2) {{/U}} through two or three different languages to their {{U}}(3) {{/U}} Again, a word from one language may pass into other languages and {{U}}(4) {{/U}} a new meaning. The word "etiquette", which is {{U}}(5) {{/U}} French origin and originally meant a label, {{U}}(6) {{/U}} a sign, passed into Spanish and kept its original meaning. So in Spanish the word "etiquette" today is used to {{U}}(7) {{/U}} the small tags which a store {{U}}(8) {{/U}} to a suit, a dress or a bottle. The word "etiquette" in French, {{U}}(9) {{/U}}, gradually developed a different meaning.

Consider the word "breakfast". "To fast" is to go for some period of time without {{U}}(14) {{/U}} .
