单选题Malnutrition "Much of the sickness and death attributed to the major communicable diseases is in fact caused by malnutrition which makes the body less able to withstand infections when they strike", said Dr. Hiroshi Nakajima, Director-General of the World Health Organization (WHO), in his statement on the first day of the World Food Summit organized by the Food and Agriculture Organization of the United Nations in Rome, Italy, from 13 to 17 November, 1996. "At the same time," he added, "in developing countries today, malnutrition is the cause of 174 million children under five years of age being underweight, and 230 million being stunted in their growth." Such figures represent deprivation, suffering and wasted human potential on a scale that is unacceptable from every point of view. Whether we think in terms of humanitarian concern, common justice or development needs, they demand a response, both from national governments and from international community. " At the end of January 1996, 98 countries had national plans of action for nutrition and 41 countries had one under preparation, in keeping with their commitments made at the International Conference on Nutrition in Rome in December 1992. The global situation, however, remains grim. Over 800 million people around the world still cannot meet basic needs for energy and protein, more than 2,000 million people lack essential micronutrients, and hundreds of millions suffer from diseases caused by unsafe food and unbalanced diets. In sheer numbers, iron is the most prevalent micronutrient deficiency. Mainly women of reproduction age and children under five are affected by iron deficiency with prevalence hovering around 50% in developing countries. Among various regions in the world, it is South Asia which is hit hardest with prevalence reaching 80% in some countries. In infants and young children even mild anemia is associated with impaired intellectual as well as physical development. In older children and adults iron deficiency reduces work capacity and output. It also leads to increased accidents at work. While there is no single remedy, a combination of several preventive approaches is believed to work best. Dietary improvement includes consumption of iron-and vitamin C-rich foods and foods of animal origin, and avoiding drinking tea or coffee with or soon after meals, Iron supplementation of foods, particularly of staple cereals, is practiced in a growing number of countries. Iron supplementation is the most common approach, particularly for pregnant women.

单选题The Modern Vegetarian Movement Today vegetarianism is trendy -25 percent of adolescents even think it's "cool". The success of vegetarian cosmetics and vegetarian foods like veggie dogs and turkey is a testament to the diet's popularity. Groups that promote vegetarianism and animal rights, like the Humane Society of the United States (HSUS) and People for the Ethical Treatment of Animals (PETA), have tremendous lobbying (游说) power with major companies. But vegetarianism hasn't always been so generally accepted, nor has it always been linked with the animal - rights movement. In 17th - and 18th - century Europe, some Protestant groups embraced vegetarianism as a moral directive - a way to be sinless. By the 19th century, European and North American vegetarianism had become a fringe (外围的) health movement. Adherents promoted the dietary benefits of vegetarianism -even coupling it with temperance (戒酒) and anti - tobacco movements. Modem, organized vegetarianism began with the formation of the Vegetarian Society in 1847 by the Bible Christian Sect of England. Within a year, the Society had 478 members. It wasn't until the mid 20th century that vegetarianism partnered with animal rights movement. America's most notorious animal rights organization, PETA, vigorously protests against all meat, animal products and animal testing. It is best known for its bold ad campaigns. The HSUS takes a less strict approach. It accepts that people will eat meat and focus instead on reducing meat consumption, replacing animal products and improving farming techniques. Both PETA and the HSUS, however, are powerful political machines: They hold stock in companies like Tyson, Wal - Mart, McDonald's and Smithfield's. The modem vegetarian movement is getting ever more powerful.

单选题Where Have All the Bees Gone? Scientists who study insects have a real mystery on their hands. All across the country, honeybees are leaving their hives and never returning. Researchers call this phenomenon Colony Collapse Disorder. According to surveys of beekeepers across the country, 25 to 40 percent of the honeybees in the United States have vanished from their hives since last fall. So far, no one can explain why. Colony collapse is a serious concern because bees play an important role in the production of about one-third of the foods we eat. As they feed, honeybees spread pollen from flower to flower. Without this process, a plant can"t produce seeds or fruits. Now, a group of scientists and beekeepers have teamed up to try to figure out what"s causing the alarming collapse of so many colonies. By sharing their expertise in honeybee behavior, health, and nutrition, team members hope to find out what"s contributing to the decline and to prevent bee disappearance in the future. It could be that disease is causing the disappearance of the bees. To explore that possibility, Jay Evans, a researcher at the United States Department of Agriculture (USDA) Bee Research Laboratory, examines bees taken from colonies that are collapsing. "We know what a healthy bee should look like on the inside, and we can look for physical signs of disease," he says. And bees from collapsing colonies don"t look very healthy. "Their stomachs are worn down, compared to the stomachs of healthy bees," Evans says. It may be that a parasite is damaging the bees digestive organs. Their immune systems may not be working as they should. Moreover, they have high levels of bacteria inside their bodies. Another cause of Colony Collapse Disorder may be certain chemicals that farmers apply to kill unwanted insects on crops, says Jerry Hayes, chief bee inspector for the Florida Department of Agriculture. Some studies, he says, suggest that a certain type of insecticide affects the honeybee"s nervous system (which includes the brain) and memory. "It seems like honeybees are going out and getting confused about where to go and what to do," he says. If it turns out that a disease is contributing to colony collapse, bees, genes could explain why some colonies have collapsed and others have not. In any group of bees there are many different kinds of genes. The more different genes a group has, the higher the group"s genetic diversity. So far scientists haven"t determined the role of genetic diversity in colony collapse, but it"s a promising theory, says Evans.

The first comprehensive study on the nation's oral health, released recently by the Office of the U. S. Surgeon General, calls dental and oral diseases a "silent epidemic (流行的)", even in children. The report states that more than 51 million school hours are lost each year to dental-related illness. In fact, a recent study pointed to dental care as the most common unmet health need among American children. To help counter this, the American Academy of Periodontology (牙周病学) (AAP) is launching an effort to educate children and parents about the prevention of dental diseases in children. "This is important because oral problems can impact self-esteem for children and lead to problems of eating, speaking and attending to learning," said Michael McGuire, president of the AAP. Common dental problems seen in children are cavities (龋洞) and gingivitis (龈炎),which are found in the majority of U. S. children. "When these problems are not caught early and treated, they can develop into more severe problems and cause unnecessary suffering," said McGuire. "However, much of the time, oral problems are avoidable problems." In the Rio Grande Valley in Texas, a group of more than 120 dentists (牙医) volunteers to deliver dental care to thousands of low-income children each year with its Mobile Dental Unit that travels from school to school. "According to the Surgeon General's Report, about 37 percent of children have not had a dental visit before starting school," said McGuire. When children don't see dentists, they miss the opportunity to have problems caught early before they develop into larger, more expensive problems to treat, and parents miss the opportunity to learn how to promote good oral habits in their children.

单选题In the U. S. , Straus and his colleague Mallie Paschall of the Pacific Institute for Research and Evaluation, looked at 1,510 children--806 kids ages 2 to 4, and 704 ages 5 to 9--and found that roughly three--quarters had endured some kind of corporal punishment in the previous two weeks, according to interviews with the mothers. Researchers measured the children's IQ initially, then again four years later. Those kids who hadn't been spanked in the initial survey period scored significantly better on intelligence and achievement tests than those who had been hit. Among the 2 - to - 4 - year - olds, the difference in IQ was five points ; among the older kids, there was a 2.8 - point gap. That association held after taking into account parental education, income and other environmental factors, says Straus. Which group of the children scored better in the survey?A.

单选题Keep on Fighting Turning once again to the question of invasion, I would observe that there has never been a period in all these long centuries of which we boast when an absolute guarantee against invasion, still less against serious raids, could have been given to our people. In the days of Napoleon the same wind which would have carried his transports across the Channel might have driven away the blockading (封锁) fleet. There was always the chance, and it is that chance which has excited and befooled (愚弄的) the imaginations of many continental tyrants. Many are the tales that are told. We are assured that novel methods will be adopted, and when we see the originality of malice (怨恨), the ingenuity of aggression, which our enemy displays, we may certainly prepare ourselves for every kind of novel stratagem (战略) and every kind of brutal and treacherous (奸的) maneuver (花招). I think that no idea is so outlandish (古怪的) that it should not be considered and viewed with a searching, but at the same time, I hope, with a steady eye. We must never forget the solid assurances of sea power and those which belong to air power if it can be locally exercised. I have, myself, full confidence that if all do their duty, if nothing is neglected, and if the best arrangements are made, as they are being made, we shall prove ourselves once again able to defend our island home, to ride out the storm of war, and to outlive the menace (威胁) of tyranny, if necessary for years, if necessary alone. At any rate, that is what we are going to try to do. This is the resolve of his Majesty"s government—every man of them. This is the will of parliament and the nation. The British Empire and the French republic, linked together in their cause and in their need, will defend to the death their native soil, aiding each other like good comrades to the utmost of their strength. Even though large tracts of Europe and many old and famous states have fallen or may fall into the grip of the Gestapo and all the odious (可憎的) apparatus of Nazi rule, we shall not flag (变弱) or fail. We shall go on to the end, we shall fight in France, we shall fight on the seas and oceans, we shall fight with growing confidence and growing strength in the air, we shall defend our island, whatever the cost might be, we shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills, we shall never surrender, and even if, which I do not for a moment believe, this island or a large part of it were subjugated (征服) and starving, then our empire beyond the seas, armed and guarded by the British fleet, would carry on the struggle, until, in God"s good time, the new world, with its power and might, steps forth to the rescue and the liberation of the old.

单选题Why People Use Pseudonyms? You can"t choose the name you are given at birth, but in many countries you can change it legally when you reach adult hood of course, most people never change their names 1 they feel unhappy about them. However, some people do 2 this course of action—particularly artists! What makes an artist want to change their name? Sometimes it"s for purely 3 reasons, such as the Nobel Prize winning poet from Chile, Neflali Reyes. He didn"t want his father to 4 he was writing poetry, so he changed his name to Pablo Neruda when he was a young man. 5 other times the reason may appear eccentric; take the case of the Portuguese poet Fernando Pessoa, 6 wrote under 75 different names. The reason? "When I use a different name, I always write in a different way," he explained. In most cases, 7 , the reason is for social, historical, political, or cultural reasons. Here are some of the most 8 . The person"s real name is just 9 long and difficult to remember. Let"s be honest, Madonna Louise Ciccone is not as 10 to remember as just plain "Madonna". And short names are much easier to remember: William Bradley became Brad Pitt and Edson Arantes do Nascimento became Pale. Sometimes names are changed for marketing 11 . For example, if a name sounds too "foreign", it may be changed to something that is more recognizable in a 12 . So in the film world, Ramon Estevez adopted the name Martin Sheen. Or maybe the artist"s real name doesn"t sound very attractive—Chad Everett does 13 a lot better than Raymond Cramton. Artists sometimes 14 the name of someone they admire. Robert Zimmerman changed his name to Boo Dylan because of his admiration for the Welsh poet, Dylan Thomas. Another reason may be practicality: in the past, women found it very difficult to get published. To 15 this situation they sometimes gave themselves men"s names, so the English author Mary Ann Evans became George Eliot, and she did get her books published!
