单选题Food The U. S. food supply is the most varied and abundant in the world. Americans spend a smaller share of their disposable income on food than citizens of any other country and choose from an average of 50,000 different food products on a typical outing to the supermarket. In 1994, the fowl supply provided an estimated 3,800 calories per person per day, enough to supply every American with more than one and a half times their average daily energy needs. Given this abundance, few of the Nations resources have traditionally been devoted to measuring or reducing food waste. In recent years, growing concern about hunger, resource conservation, and the environmental and economic costs associated with food waste have raised public awareness of food loss. This in turn has accelerated public and private efforts to make better use of available, food supplies by recovering safe and nutritious food that would otherwise be wasted. Of course, not all food that is lost is suitable for consumption. Some losses like the condemnation of diseased animals at the slaughtering house (屠宰场), or the discard of rotten fruit from the produce shelf at the supermarket are necessary to ensure the safetyand health of the U. S. food supply. Such foods are not recoverable for human use. Likewise, plate fragments are appropriately discarded at eating establishments out of health considerations. In addition, not all food that is lost is economically recoverable. Food recovery efforts are often limited by financial restraints that make it difficult to match recovered food with potential recipients. Nevertheless, large quantities of healthy, edible food are lost at every stage of the marketing system. Example of such losses include meats, bread, and other foods prepared by a restaurant or hotel but never served and the discard of defected or over-ripe .produce, which maybe difficult to sell out for some reasons, but are otherwise nutritious and safe.

One hundred years ago the average woman lived to be 45. But now, she can live until at least 80. One of the main reasons for people living longer is that we know how to look after ourselves better. We know which foods are good for us and what we have to eat to make sure our bodies get all the healthy things they need. We know why we sometimes get ill and what to do to get better again. And we know how important it is to do lots of exercise to keep our hearts beating healthily. But in order that we don't slip back into bad habits, let's have a look at what life was like 100 years ago. Families had between 15 and 20 children, although many babies didn't live long. Children suffered from lots of diseases, especially rickets (佝偻病) and scurvy (坏血病), which are both caused by bad diets. This is because many families were very poor and not able to feed their children well. Really poor families who lived in crowded cities like London and Manchester often slept standing up, bending over a piece of string, because there was no room for them to lie down. People didn't have fridges until the 1920s. They kept fresh food cold by storing it on windowsills (窗台板), blocks of ice, or even burying it in the garden. Some children had to start work at the age of seven or eight to earn money for their parents. If you had lived 100 years ago, you might well be selling matchsticks (火柴杆) (a job done by many children) or working with your dad by now.

单选题Breastfeeding Can Cut Cardiovascular (心血管的) Risk Breastfeeding can reduce the risk of a heart attack or stroke later in life and could prevent hundreds of 1 of deaths each year, researchers said on Friday. Babies who are breastfed have fewer childhood infections and allergies (过敏的) and are less 2 to obesity (肥胖的). British scientists have now shown that breastfeeding and slow growth in the first weeks and months of life has a protective effect 3 cardiovascular disease. "Diets that promote more rapid growth put babies at risk many years later in 4 of raising their blood pressure, raising their cholesterol (胆固醇) and increasing their tendency to diabetes (糖尿病) and obesity—the 5 main risk factors for stroke and heart attack." said Professor Alan Lucas of the Institute of Child Health in London. "Our evidence suggests that the reason why breastfed babies do better is because they grow more 6 in the early weeks." Lucas said the effects of breastfeeding on blood pressure and cholesterol later in life are greater than 7 adults can do to control the risk factors for cardiovascular disease, other than taking drugs. An estimated 17 million people die of 8 disease, particularly heart attack and strokes each year, according to the World Health Organization. Lucas and his colleagues compared the health of 216 teenagers 9 as babies had either been breastfed or given different nutritional baby formulas. They reported their 10 in medical journal. The teenagers who had been 11 had a 14 percent lower ratio of bad to good cholesterol and lower concentrations of a protein that is a marker for cardiovascular disease risk. The researchers also found that 12 of the child"s weight at birth, the faster the infants grew in the early weeks and months of life, the 13 was their later risk of heart disease and stroke. The effect was the 14 for both boys and girls. "The more human milk you have in the new born period, the lower your cholesterol level is and the lower your blood pressure is 16 years 15 ," Lucas said.

单选题Grooming and Personal Hygiene of Americans Grooming and personal hygiene have been around for ages. It's hard to imagine a time when people weren't concerned with taking care of their appearance and their bodies. Perhaps these practices started when Adam first took a bath and combed his hair before going on a date with Eve. Or maybe they began when Eve put on some herbal makeup to make herself more beautiful. No matter where they started, grooming and personal hygiene have become important parts of everyone's daily routine. There used to be an old joke in America that people should take a bath once a week, whether they need one or not. In fact, though, Americans generally take a bath or more commonly, a shower every day. But in contrast to some cultures, most Americans get their shower in the morning, so they can start the day fresh. And instead of going to a beauty parlor for a shampoo, many Americans prefer to wash and style their own hair. So if Americans have a bad hair day, they have no one to blame but themselves. But most people in America do head for the beauty parlor or barbershop occasionally for a haircut, a perm or just some friendly conversation. Americans are known for having very sensitive noses. In America, "BO." (body odor) is socially unacceptable. For that reason, Americans consider the use of deodorant or antiperspirant a must. Ladies often add a touch of perfume for an extra fresh scent. Men may splash on after-shave lotion or manly-smelling cologne. Another cultural no-no in America is bad breath. Americans don't like to smell what other people ate for lunch-especially onions or garlic. Their solution? Mouthwash, breath mints and even brushing their teeth after meals. Americans put great value on both grooming and personal hygiene. For some people, taking care of themselves has become almost a religion. As the old saying goes, "Cleanliness is next to godliness." Whether or not being clean and we!l-groomed brings one closer to God, it certainly brings one closer to others. Americans look down on people who don't take care of themselves, or who "let themselves go." To Americans, even if we don't have much to work with, we have to make the best of what we've got.

单选题Double Effect The Supreme Court's decisions on physician-assisted suicide carry important implications for how medicine seeks to relieve dying patients of pain and suffering. Although it ruled that there is no constitutional right to physician assisted suicide, the Court in effect supported the medical principle of "double effect", a centuries-old moral principle holding that an action having two effects—a good one that is intended and a harmful one that is foreseen—is permissible if the actor intends only the good effect. Doctors have used that principle in recent years to justify using high doses of morphine to control terminally ill patients' pain, even though increasing dosages will eventually kill the patient. Nancy Dubler, director of Montefiore Medical Center, contends that the principle will shield doctors who "until now have very, very strongly insisted that they could not give patients sufficient mediation to control their pain if that might hasten death. " George Annas, chair of the health law department at Boston University, maintains that, as long as a doctor prescribes a drug for a legitimate medical purpose, the doctor has done nothing illegal even if the patient uses the drug to hasten death. "It's like surgery," he says. "We don't call those deaths homicides because the doctors didn't intend to kill their patients, although they risked their death. If you're a physician, you can risk your patient's suicide as long as you don't intend their suicide. " On another level, many in the medical community acknowledge that the assisted-suicide debate has been fueled in part by the despair of patients for whom modern medicine has pro longed the physical agony of dying. Just three weeks before the Court's ruling on physician-assisted suicide, the National Academy of Science (NAS) released a two-volume report, Approaching Death: Improving Care at the End of Life. It identifies the under-treatment of pain and the aggressive use of "ineffectual and forced medical procedures that may prolong and even dishonor the period of dying" as the twin problems of end-of-life care. The profession is taking steps to require young doctors to train in hospices, to test knowledge of aggressive pain management therapies, to develop a Medicare billing code for hospital-based care, and to develop new standards for assessing and treating pain at the end of life. Annas says lawyers can play a key role in insisting that these well-meaning medical initiatives translate into better care. "Large numbers of physicians seem unconcerned with the pain their patients are needlessly and predictably suffering," to the extent that it constitutes"systematic patient abuse." He says medical licensing boards "must make it clear.., that painful deaths are presumptively ones that are incompetently managed and should result in license suspension. /

单选题{{B}}第三篇{{/B}} In the 1960s, medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful events. They appreciated the tricky point that any major change can be stressful. Negative events like "serious illness of a family member" were high on the list, but so were some positive life-changing events, like marriage. When you take the Holmes-Rahe test you must remember that the score does not reflect how you deal with stress--it only shows how much you have to deal with. And we now know that the way you handle these events dramatically affects your chances of staying healthy. By the early 1970s, hundreds of similar studies had followed Holmes and Rahe. And millions of American who work and live under stress worried over the reports. Somehow, the research got boiled down to a memorable message. Women's magazines ran headlines like "Stress causes illness!" If you want to stay physically and mentally healthy, the articles said, avoid stressful events. But such simplistic advice is impossible to follow. Even if stressful events are dangerous, many --like the death of a loved one -- are impossible to avoid. Moreover, any warning to avoid all stressful events is a prescription(处方)for staying away from opportunities as well as trouble. Since any change can be stressful, a person who wanted to be completely free of stress would never marry, have a child, take a new job or move. The notion that all stress makes you sick also ignores a lot of what we know about people. It assumes we're all vulnerable (脆弱的)and passive in the face of adversity (逆 `境5. But what about human initiative and creativity? Many come through periods of stress with more physical and mental vigor than they had before. We also know that a long time without change or challenge can lead to boredom, and physical and mental strain.
