By the mid-nineteenth century, the term "icebox" 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 (酒馆), 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 of 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 fridge, had bean invented. Making an efficient icebox was not as easy as we might now suppose. In the early nineteenth century, the knowledge of the physics of heat, which was essential to a science of refrigeration, was rudimentary (未发展的). The commonsense notion that the best icebox was one that prevented the ice from melting was of coarse mistaken, for it was the melting of the ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping up 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, and 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. Where was ice used after the Civil War

请根据下面短文回答题 You have probably seen ads (广告) in newspaper or on television for mail-order companies. Perhaps a catalogue (商品目录) has been sent to you. Why do people buy things they have not seen in person Some people believe that things can be bought more cheaply by mail. Another good thing about buying by mail is that it is easier and more enjoyable to sit at home and work through a catalogue than to shop around the stores. With a catalogue from a large company, you have your own shop window for almost everything you want to buy. Buying from a catalogue is so easy. It saves the shopper time and trouble. Sometimes, it saves the shopper money, too. But people often buy more than they can really afford (付得起) or need, because many things look so good to them. They can probably pay a certain part of the full price - a down payment. Then they pay a certain amount of money every month until the goods is paid for in full. But by then they often find what they have bought are of no use at all. According to the text, people can get the goods first and pay ______.

A. [A] bit by bit
B. a few months later
C. until it is of no use at all

The Next Disaster: Are We ReadyAre We Really Prepared After the attacks on September 11 and the hurricanes that slammed the Gulf Coast last year, you’d expect our major cities to be ready with disaster plans that will save lives and property. There’s no doubt we’ll be hit again—maybe even harder—because the list of possible calamities (灾难) is long: from a bird flu pandemic to a massive California earthquake, to more monster storms, to another terrorist attack. But are we really prepared to protect people, as well as their homes and businesses Every major urban area has received federal funding, much of it from the Department of Homeland Security (DHS), in order to make their cities more secure. But there are no set criteria for measuring preparedness (the feds are working on that), and the quality of disaster plans varies widely throughout the country. So we decided to do an independent assessment of 10 high-risk urban areas, focusing on key security indicators. We analyzed public data, consulted with federal and local emergency workers, and contacted the mayors’ offices to gauge (测量) the readiness of these cities to meet both natural and man-made disasters. Our criteria fell under three main categories: Emergency Readiness, Crisis Communications, and Medical Response.Emergency Readiness Are there at least 1,000 first responders (such as police, fire and EMTs) per 100,000 residents They’re our first line of protection in almost any disaster situation—professionals who are trained to handle everything from rescuing victims to providing first aid, to enforcing quarantines (封锁), to directing traffic for evacuations (疏散). Are there federal search-and-rescue teams based within 50 miles Large cities often have specialized teams to deal with such things as high-rise-building rescues or hazardous chemical spills. But these squads are sometimes small, ill-equipped, or run on a shoestring. This is not true of federal urban search-and-rescue task forces that the DHS supports across the country. Each task force is made of 62 members and 4 canines, as well as a "comprehensive cache" of equipment. DHS task forces are not automatically assigned; a city needs to apply and present its case. Has the city or state earned "green status" from the Centers for Disease Control and Prevention Suppose that in the midst of a flu pandemic or bio terror attack, your city ran low on critical medicines. The CDC stands ready to help by distributing drugs and medical equipment from its Strategic National Stockpile. But the agency wants to know that a city or state is able to quickly mobilize hundreds of health workers and volunteers trained to handle the logistics, and has space set aside for storage and refrigeration. You’re best off if your city has earned the CDC’s "green status"—even if the state itself has not—because it means local health teams can handle the supplies on their own. Does the city website explain clearly what to do in case of evacuation Who can forget the images of stranded New Orleans residents, or the 5-mph crawl out of Houston It turned out that New Orleans’s evacuation plans were both inadequate and poorly communicated. One way cities can avoid a similar nightmare is to put clear and easy-to-find evacuation information on their websites. Some cities, such as Boston and Washington, post the preferred street routes. Others, like Las Vegas, won’t disclose details due to security fears, but their websites may provide ways to quickly get evacuation details when you need them (such as numbers to call or alert services you can sign up for). Among the more important things to address are people without vehicles of their own (a huge failing in New Orleans) and instructions for pet owners. Does the website include details for residents with special needs In July 1995, a vicious heat wave killed nearly 500 people in Chicago; a disproportionate number of them were older residents who lived alone. In any crisis, the elderly and disabled can be uniquely vulnerable. That’s why cities such as Houston are creating registries of residents who would need special help. Such lists would indicate, for instance, that a certain person in a certain apartment building is wheel-chair-bound. Other cities are instructing people with disabilities to call 911 for assistance—though this relies on phone systems that could be overloaded or go dead. If a city’s disaster planning shows no awareness of special-needs people, it isn’t complete.Crisis Communications Can first responders—police, fire and medical—talk to one another On September 11, firefighters died inside the World Trade Center because they could not make contact with police helicopters trying to radio warnings. Incompatible communications is a country-wide problem, and converting or replacing decades-old radio systems can be a long, expensive process. Cities have gotten a big boost if they’ve taken part in RapidCom, a DHS program providing technical assistance and training that speeds up the transition. Has the city adopted E911 Many cities have upgraded their 911 call centers in recent years, but they’re even better prepared if they’ve incorporated "E911" (or "enhanced 911"). This technology enables emergency operators to identify the precise location of cell-phone callers through GPS systems. If you wind up stranded in floodwaters, E911 could save your life. Does the city provide 24-bout emergency alerts What if an evacuation order goes out, but it’s 3 a.m. and you’re sound asleep Not a problem if your city has a way of alerting you at any time of day. Some rely on street sirens (警报器) to do the trick. Others have used their websites to invite residents to sign up for e-mail notifications or automated phone calls in an emergency.Medical Response Are there at least 500 hospital beds for every 100,000 residents Getting to victims quickly is a critical first step. But you’d better have a place to take them for treatment. A reasonable standard, according to preparedness experts, is 500 hospital beds for every 100,000 people—a ratio that would likely mean a city could find enough spare beds in an emergency. Of course, beds alone won’t help a massive number of burn victims or people suffering from chemical exposure unless the hospital is prepared to treat them. But all the cities in our survey have specialty units in their hospitals that can handle such cases. Are local teams trained to respond quickly and work together If an urban area was targeted by weapons of mass destruction, city health officials couldn’t just wait for federal help to arrive. First responders and hospitals would need to react fight away. They could also need medical volunteers—say, to help vaccinate people or distribute medicines and supplies. How to ensure that all these professionals and volunteers work together as seamlessly as possible If a city is part of DHS’s Metropolitan Medical Response System, it has obtained federal assistance in developing plans, and has received critical training and equipment. Are there labs nearby that specialize in biological and chemical threats The CDC is on the cutting edge with its Laboratory Response Network—integrated labs nationwide that have the equipment and expertise to quickly identify pathogens and toxic chemicals. An LRN lab in Florida was the first to detect anthrax (炭疽热) in terrorist mailings in 2001. Laboratories can be members only if they have highly trained staff and exceptional facilities, as well as a track record of testing accuracy. A handful of LRN labs qualify as "Level 1", meaning they can test for chemical poisons such as mustard and nerve agents. If a city has earned the CDC’s "green status", it means that its local health teams can ______ on their own.
