单选题Diet and exercise are keys to healthy giving. But you know all this. So our aim is to give you the shortcuts, the little-known tricks and proven methods to help prevent boredom and hopelessness in your quest for good health. That"s what the Health and Fitness Tips Site is all about. 21 Make it a daily challenge to find ways to move your body. Climb stairs if given a choice between that and escalators or elevators. Walk your dog; chase your kids; toss balls with friends; mow the lawn. Anything that moves your limbs is not only a fitness tool, it"s a stress buster. Think "move" in small increments of time. It doesn"t have to be an hour in the gym or a 45-minute aerobic dance class or tai chi or kickboxing. But that"s great when you"re up to it. Meanwhile, move more. Thought for the day. Cha, Cha, Cha...Then do it! 22 Avoid the obvious fat-contained food such as fried foods, burgers and other fatty meats (i.e. pork, bacon, ham, ribs and sausage). Dairy products such as cheese, cottage cheese, milk and cream should be eaten in low fat versions. Nuts and sandwich meats, mayonnaise (蛋黄酱), margarine (人造黄油), butter and sauces should be eaten in limited amounts. Most are available in lower fat versions such as substitute butter, fat free cheeses and mayonnaise. Thought for the day: Lean, mean, fat-burning machine... Then be one! 23 The jury is definitely in on this verdict. Ever since 1960 when the Surgeon General announced that smoking was harmful to your health, Americans have been reducing their use of tobacco products that kill. Just recently, we"ve seen a surge in smoking in adolescents and teens. Could it be the Hollywood influence? It seems the stars in every movie of late smoke cigarettes. Beware. Warn your children of the false romance or "tough guy" stance of Hollywood smokers. Thought for the day. Give up just one cigarette then the next one. 24 Easier said than done, stress busters (压力消除器) come in many forms. Some techniques recommended by experts are to think positive thoughts. Spend 30 minutes a day doing something you like. Soak in a hot tub; walk on the beach or in a park; read a good book; visit a friend; play with your dog; listen to soothing music; watch a funny movie. Get a massage, a facial or a haircut. Meditate. Count to ten before losing your temper or getting angry. Avoid difficult people when possible. Thought for the day. When seeing red, think pink clouds..., then float on them. 25 If you can"t live in a smog-flee environment, at least avoid smoke-filled rooms, high traffic areas, breathing in highway fumes and exercising near busy thoroughfares. Exercise outside when the smog-rating is low. Exercise indoors in air conditioning when air quality is good. Plant lots of shrubbery in your yard. It"s a good deterrent for pollution and dirt from the street. Thought for the day. Smoke gets in your eyes..., and your mouth, and your nose and your lungs as do pollutants. A. Eat Less B. Quit Smoking C. Cut Fat D. Move More E. Reduce Stress F. Control Your Temper G. Protect Yourself from Pollution

单选题How many really suffer as a result of labor market problems? This is one of the most critical yet contentious social questions. In many ways, our social statistics exaggerate the degree of hardship. Unemployment does not have the same direct consequences today as it did in the 1930s when most of the unemployed were primary breadwinners, when income and earnings were usually much close to the margin of subsistence, and when there were no countervailing social programs for those failing in the labor market. Increasing affluence, the rise of families with more than one wage earner, the growing predominance of secondary earners among the unemployed, and improved social welfare protection have unquestionably mitigated the consequences of joblessness. Earnings and income data also overstate the dimensions of hardship. Among the millions with hourly earnings at or below the minimum wage level, the overwhelming majority are from multiple-earners, relatively affluent families. Most of those counted by the poverty statistics are elderly or handicapped or have family responsibilities which keep them out of the labor force, so the poverty statistics are by no means an accurate indicator of labor market pathologies. Yet there are also many ways our social statistics underestimate the degree of labor-market- related hardship. The unemployment counts exclude the millions of fully employed workers Whose wages are so low that their families remain in poverty. Low wages and repeated unemployment frequently interact to undermine the capacity for self-support. Since the number experiencing joblessness at some time during the year is several times the number unemployed in any month, those who suffer as a result of forced idleness can equal or exceed average annual unemployment, even though only a minority of the jobless in any month really suffer. For every person counted in the monthly unemployment tallies, there is another working part-time because of the inability to find full-time work, or else outside the labor dependent, neglecting the needs of the working poor, so that the dramatic expansion of cash and in-kind transfers does not necessarily mean that those failing in the labor market are adequately protected. As a result of such contradictory evidence, it is uncertain whether those suffering seriously as a result of labor market problems number in the hundreds of thousands or the tens of millions, and, hence, whether high levels of joblessness can be tolerated or must be countered by job creation and economic stimulus. There is only one area of agreement in this debate—that the existing poverty, employment, and earnings statistics are inadequate for one of their primacy applications, measuring the consequences of labor market problems.

单选题The age of gilded youth is over. Today"s under-thirties are the first generation for a century who can expect a lower living standard than their parents. Research into the lifestyles and prospects of people who were born since 1970 shows that they are likely to face a lifetime of longer working hours, lower job security and higher taxes than the previous generation. When they leave work late in the evening, they will be more likely to return to a small rented flat than to a house of their own. When, eventually, they retire, their pensions are far lower in real terms than those of their immediate forebears. These findings are revealed in a study of the way the ageing of Britain"s population affecting different generations. Anthea Tinker, professor of social gerontology (老人学) at King"s College London, who carried out much of the work, said the growth of the proportion of people over 50 had reversed the traditional flow of wealth from older to younger generations. "Today"s older middle-aged and elderly are becoming the new winners," she said. "They made relatively small contributions in tax but now make relatively big claims on the welfare system. Generations born in the last three to four decades face the prospect of handing over more than a third of their lifetime"s earnings to care for them. " The surging number of older people, many living alone, has also increased demand for property and pushed up house prices. While previous generations found it easy to raise a mortgage, today"s under-thirties have to live with their parents or rent. If they can afford to buy a home it is more likely to be a flat than a house. Laura Lenox-Conyngham, 28, grew up in a large house and her mother did not need to work. Unlike her wealthy parents, she graduated with student and postgraduate loan debts of ￡13,000. She now earns about ￡20,000 a year, preparing food to be photographed for magazines. Her home is a one-bedroom flat in central London and she sublets (转租) the lounge sofa-bed to her brother. "My father took pity and paid off my student debts," she said. "But I still have no pension and no chance of buying a property for at least a couple of years—and then it will be something small in a bad area. My only hope is the traditional one of meeting a rich man." Tinker"s research reveals Lenox-Conyngham is representative of many young professionals, especially in London, Manchester, Edinburgh and Bristol.

单选题Whatever happened to the death of newspaper? A year ago the end seemed near. The recession threatened to remove the advertising and readers that had not already fled to the internet. Newspapers like the San Francisco Chronicle were chronicling their own doom. America"s Federal Trade Commission launched a round of talks about how to save newspapers. Should they become charitable corporations? Should the state subsidize them? It will hold another meeting soon. But the discussions now seem out of date. In much of the world there is the sign of crisis. German and Brazilian papers have shrugged off the recession. Even American newspapers, which inhabit the most troubled corner of the global industry, have not only survived but often returned to profit. Not the 20% profit margins that were routine a few years ago, but profit all the same. It has not been much fun. Many papers stayed afloat by pushing journalists overboard. The American Society of News Editors reckons that 13,500 newsroom jobs have gone since 2007. Readers are paying more for slimmer products. Some papers even had the nerve to refuse delivery to distant suburbs. Yet these desperate measures have proved the right ones and, sadly for many journalists, they can be pushed further. Newspapers are becoming more balanced businesses, with a healthier mix of revenues from readers and advertisers. American papers have long been highly unusual in their reliance on ads. Fully 87% of their revenues came from advertising in 2008, according to the Organization for Economic Cooperation & Development (OECD). In Japan the proportion is 35%. Not surprisingly, Japanese newspapers are much more stable. The whirlwind that swept through newsrooms harmed everybody, but much of the damage has been concentrated in areas where newspaper are least distinctive. Car and film reviewers have gone. So have science and general business reporters. Foreign bureaus have been savagely cut off. Newspapers are less complete as a result. But completeness is no longer a virtue in the newspaper business.

单选题When a friend hurts you, your instinct is to protect yourself. But that makes it harder to ______ up problems.

单选题Earlier this year I met with a group of women in Matela, a small farming village in Tanzania, and we discussed something that"s been on all of our minds lately: finding a safe place to save money. The women said their babies were getting sick from malaria (疟疾), and they could afford the drugs if they saved money over time—but with no access to formal savings accounts, they had a hard time safeguarding cash. So they saved in risky and inefficient ways. They made loans to each other, or bought goats or jewelry, then sold them if they suddenly needed money. The success of microloans has opened new opportunities for many poor people and has been a crucial factor in reducing poverty. But loans are not enough. Savings accounts could help people in the developing world with unexpected events, accumulate money to invest in education, increase their productivity and income, and build their financial security. Fortunately, this is a moment of opportunity. New policy ideas are uniting in ways that will lower the cost of savings and bring safe financial services to the doorsteps of the poor. One exciting trend is agent bank, in which stores and post offices serve as banking outlets. Banks still manage and guarantee the deposits, but they rely on the infrastructure (基础设施) of other outlets to deal with clients where there are no bank branches. The phenomenal growth of mobile phones in the developing world presents another opportunity. M-Pesa, the mobile-phone cash-transfer service in Kenya, has signed up more than 5 million subscribers in two years and recently expanded to Tanzania. This new idea is opening markets and transforming lives. A split-second M-Pesa transaction costs as little as 30 cents and replaces a day of risk and expense just to send someone money or carry earnings home. At the Gates Foundation, it has been committed more than $350 million to make financial services widely accessible to the poor because safe places to save can help break the cycle of poverty. If action is taken on this moment, then within a generation, billions of people will have the chance to build up their savings and live the healthy, productive lives that they deserve.
