单选题Avalanche and Its Safety An avalanche is a sudden and rapid flow of snow, often mixed with air and water, down a mountainside. Avalanches are 1 the biggest dangers in the mountains for both life and property. All avalanches are caused by an over-burden of material, typically snowpack, that is too massive and unstable for the slope 2 supports it. Determining the critical load, the amount of over-burden which is 3 to cause an avalanche, 4 a complex task involving the evaluation of a number of factors. Terrain slopes flatter than 25 degrees or steeper than 60 degrees typically have a low 5 of avalanche. Snow does not 6 significantly on steep slopes; also, snow does not 7 easily on flat slopes. Human-triggered avalanches have the greatest incidence when the snow"s angle of rest is 8 35 degrees and 45 degrees; the critical angle, the angle at which the human incidence of avalanches is greatest, is 38 degrees. The rule of thumb is: A slope that is 9 enough to hold snow but steep enough to ski has the potential to generate an avalanche, regardless of the angle. Additionally, avalanche risk increases with 10 that is, the more a slope is disturbed by skiers, the more likely it is that an avalanche will occur. Due to the complexity of the subject, winter travelling in the backcountry is never 100% safe. Good avalanche safety is a continuous 11 , including route selection and examination of the snowpack, weather 12 , and human factors. Several well- known good habits can also 13 the risk. If local authorities issue avalanche risk reports, they should be considered and all warnings should be paid 14 to. Never follow in the tracks of others without your own evaluations; snow conditions are almost certain to have changed since they were made. Observe the terrain and note obvious avalanche paths where plants are 15 or damaged. Avoid traveling below others who might trigger an avalanche.

单选题Life Expectancy in the Last Hundred Years A. hundred years ago, life expectancy in developed countries was about 47; in the early 2lst century, men in the United States and the United Kingdom can expect to live to about 74, women to about 80, and these (1) are rising all the time.

(11) people's general health has improved with improvements in our general environment: cleaner air, better means of preserving food, better and warmer housing, and better understanding of nutrition. Genetically, we should all be able to live to about 85 but (12) people do live longer today, there are still some big killers around that are preventing us from consistently reaching that age. The problems that affect people today are the more chronic illnesses, such as heart disease and strokes, and those (13) by viruses, such as influenza and AIDS. Of course, cancer is a huge killer as well. In most cases these diseases affect (14) people, but there are worrying trends in the developed world with problems such as obesity (15) more heart disease and illnesses such as diabetes at younger ages. The killers today can be classed as "lifestyle diseases" , which means that it may be possible to halt their progress.

单选题Shopping at Second-hand Clothing Stores　　 When 33-year-old Pete Barth was in college，shopping at second-hand clothing　stores was just something he did - “like changing the tires on his car.” He looked at his budget and decided he could save a lot of money by shopping for clothes at thrift shops.　　“Even new clothes are fairly disposable (可丢掉的)and wear out after a couple of years，” Barth said. “In thrift shops，you can find some great stuff whose quality is better than new clothes.”　　Since then，Barth，who works at a Goodwill thrift shop in the US state of Florida，has found that there are all kinds of reasons for shopping for second-hand clothing. Some people，like him，shop to save money. Some shop for a crazy-looking shirt. And some shop as a means of conserving energy and helping the environment.　　Pat Akins，an accountant at a Florida Salvation Army (SA)(救世军)thrift shop，said that，for her，shopping at thrift shops is a way to help the environment.　　“When my daughter was little，we looked at it as recycling，” Akins said. “Also，why pay 30 dollars for a new coat when you can get another one for a lot less？”　　 Akins said that the SA has shops all over the US - “some as big as department　stores.” All of the clothes are donated (捐赠)，and when they have a surplus (盈余)，they'll have “stuff a bag” specials，where customers can fill a grocery sack With clothes for only 5 or 10 dollars.　　Julia Slocum，22，points out，however，that the huge amount of second-hand clothing in the US is the result of American wastefulness.　　I'd say that second-hand stores are the result of our wasteful，materialistic culture，“ said Slocum，who works for a pro-conservation organization，the Center for a New American Dream. ”Thrift shops prevent that waste from going to landfills (垃圾填埋场)； they give clothing a second life，provide cheaper clothing for those who can't afford new ones and generate (生成)income for charities. They also provide a way for the wealthy and middle classes to shed (摆脱)some of the guilt for their level of consumption.“

单选题Online Cancer Chat with a Safety Net Cancer Research U.K. has lanched an online chat forum for cancer patients to swap stories and share experiences on how to cope with such a devastating disease. But Cancer Chat is a forum with a difference: it has an information safety net. This means that a Cancer Research U.K. team will keep a watching brief to ensure that patients are not subjected to rogue "cancer cures" or scientifically unsound information. Anyone can have access to the messages posted on Cancer Chat but if people wish to post a message they will need to register. And Rebekah Gibbs, cancer patient and star of TV's Casualty has pledged her support for the new project. "I think Cancer Chat is a brilliant idea," she said. "I have written a public diary about what I went through with breast cancer and I have had such a heart-warming response from other people going through the same thing. "The idea of a Cancer Chat forum means you can share information about treatment and side effects and you can really open up about your feelings online in a way that can be difficult when talking to close friends and family. And with Cancer Research U.K. monitoring the forum people can be reassured about the quality of information being exchanged. " Cancer Chat will also encourage its users to check out any cancer questions on its CancerHelp U.K. website which is specially designed to give patients and their families 6,000 pages of up-to-date information that is easy to understand and explains a wide range of treatments for different types of cancer and gives details of clinical trials. There is also a U.K. database of cancer clinical trials. The award-winning website attracts around one million visitors a month and Cancer Research U.K. hopes that some of these visitors will also want to post comments on the Cancer. For those who do not have access to computers and have questions about cancer, the charity's team of cancer information nurses are available during office hours to talk over patients' concerns on the phone.

Daily cigars also increase the risk of lung cancer and cancer of the esophagus, and increase the risk of cancer of the larynx (voicebox) sixfold, say researchers at the National Cancer Institute in Bethesda, Maryland. In addition, the report revealed that smoking three or four cigars a day increased the risk of oral cancer to 8.5 times the risk for nonsmokers and the risk of esophageal cancer by four times the risk of nonsmokers. The health effects of smoking cigars is one of eight sections of the article "Cigars: Health Effects and Trends". The researchers report that, compared with a cigarette, a large cigar emits up to 90 times as much carcinogenic tobacco-specific nitrosamines. "This article provides clear and invaluable information about the disturbing increase in cigar use and the significant public health consequences for the country," said Dr. Richard Klausner, director of the National Cancer Institute, in a statement. "The data are clear — the harmful substances and carcinogens in cigar smoke, like cigarettes, are associated with the increased risks of several kinds of cancers as well as heart and lung diseases," he added. "In other words, cigars are not safe alternatives to cigarettes and may be addictive." "To those individuals who may be thinking about smoking cigars, our advice is — don't. To those currently smoking cigars, quitting is the only way to eliminate completely the cancer, heart and lung disease risks," warned Klausner. According to a National Cancer Institute press release, there haven't been any studies on the health effects on nonsmokers at cigar social events, but "... a significant body of evidence clearly demonstrates an increased lung cancer risk from secondhand smoke."

单选题What Is Market? The word market is used in a number of ways. There is a stock market and an automobile market, a retail market for furniture and a wholesale market for furniture. One person may be going to the market: another may plan to market a product. What, then is a market? A market may be defined as a place where buyers and sellers meet, goods or services are offered for sale. and transfers of ownership occur. A market may also be defined as the demand made by a certain group of potential buyers for a good or service. For instance, there is a farm market for petroleum products. The terms market and demand are often used interchangeably; they may also be used jointly as market demand. These definitions are not sufficiently precise to be useful to us here. For business purposes we define a market as people or organizations with wants (needs) to satisfy, money to spend, and the willingness to spend it. Thus in the market demand for any given product or service, there are three factors to consider—people or organizations with wants(needs),their purchasing power, and their buying behavior. We shall employ the dictionary definition of needs: the lack of anything that is required, desired, or useful. We do not limit needs to the narrow physiological requirements of food, clothing and shelter essential for survival. In our discussion the words needs and wants are used synonymously and interchangeably. In a strict interpretation, however, needs would refer to such basic physiological requirements as food, clothing, and shelter, while wants would be non-basic preferences. However, in our affluent society, little is to be gained by trying to differentiate between the two. Many of us would see as needs some items that are far beyond food, clothing, and shelter.
