Article: Why do Chinese people love hot pot so much? As the winter months begin to settle in, I find myself wondering what it is about this traditional meal, which has existed for more than 1,000 years, that makes it a Chinese food favorite.But it seems that the answer lies beyond the dish itself. Hot pot isn't just designed to keep you warm during the cold months; it's also a social experience.It's a "theater" cuisine that turns a meal into an event.There is a lot of fun for everyone to have in adding ingredients to the hot pot. Hot pot is eaten over two to three hours.For this reason, it is often, considered an evening's entertainment, and time to spend with friends and family.However, many westerners would be _ by the idea of other people sticking chopsticks in their food.When we come to eat at the table in the UK, we tend to have our own individual portions , although the experience is still a social one. A similar experience to the hot pot one can be found in Korean barbecue restaurants, which let you cook your own meat.This allows people to have their meat done however they want. For most Westerners, the idea of going to a restaurant to cook their own food is bizarre .But having given hot pot a go, I find it's now one of my favorite meals in Beijing.The steam from the pot left my clothes smelling of food when I got home, but perhaps this is also part of the experience.When the chilly wind is blowing outside, just grab some chopsticks, some good friends, and dig in.For me it's like throwing a dinner party where my taste buds and my appetite are equally satisfied in the warm company of friends.

Article: Poor Oral Health Leads to Social and Emotional Problems A new report says nearly four-billion people have major tooth decay, or cavities. That number represents more than half of the world's population. Health officials are warning that failure to repair cavities can lead to social and emotional problems. Wagner Marcenes is with the Institute of Dentistry at Queen Mary, University of London. He led a team of researchers as part of the Global Burden of Disease 2010 study. About 500 researchers attempt to collect and examine studies about all major diseases. They used the information to estimate rates of the infection. The report says untreated tooth decay is the most common of all 291 major diseases and injuries. Professor Marcenes says cavities or holes in permanent teeth are also known as caries. "Caries is a chronic disease that shares the same risk factors as cancer, cardiovascular disease. What we're having now is an increase in disease from highly developed countries happening in sub-Saharan Africa and probably it will be in other areas of Africa, too." He says an increase in tooth decay in Africa could be a result of developing countries becoming more like Western nations. "It is likely to be related to a change in diet. Our industrialized diet leads to chronic disease, which includes caries. And that may be the main explanation." Western diets are rich in sugar, a leading cause of health problems in the mouth. Wagner Marcenes says oral health problems can have a major effect on a person's quality of life. First, cavities make eating difficult. Second, people may change what they eat. They may eat softer foods that are not hard to chew. However, softer foods are often fattier foods. But professor Marcenes says the biggest issue in tooth decay is both social and mental. He says the researchers found strong evidence that the mouth has a big influence on socialization. He says many people want to hide bad teeth. They smile less and communicate less. Wagner Marcenes is calling for an "urgent, organized,... Question: What is the writer's attitude towards tooth decay? Yes or no, is the answer "concerned"?

No

Ques: Article: Farm-raised pigs are dirty, smelly animals that get no respect. They're also an environmental hazard. Their manure contains phosphorus ,which, when it rains, runs off into lakes and rivers, consuming oxygen, killing fish, stimulating algae overgrowth and emitting greenhouse gases. Doing away with the pig is not an option. Pigs provide more dietary protein, more cheaply, to more people than any other animal. Northern Europe still maintains the highest pig-to-human ratio in the world (2-1 in Denmark), but East Asia is catching up. During the 1990s, pork production doubled in Vietnam and grew by 70 percent in China--along densely populated coastlines, pig density exceeds 100 animals per square kilometer. The resulting pollution is "threatening fragile coastal marine habitats including mangroves ,coral reefs and sea grasses ,"according to a report released in February by the Food and Agriculture Organization of the United Nations. As it turns out, there is a solution to the pig problem, but it requires a change of mind-set among environmentalists and the public. Two Canadian scientists have created a pig whose manure doesn't contain very much phosphorus at all. If this variety of pig were adopted widely, It could greatly reduce a major source of pollution. But the Enviropig, as they call it, is the product of genetic modification--which is anathema to many Westerners. The Enviropig is one of many new technologies that are putting environmentalists and organic-food supporters in _ : should they remain categorically opposed to genetically modified (GM)foods even at the expense of the environment? Elsewhere, trees grown for paper could be made amenable to much more efficient processing, reducing both energy usage and toxic chemical bleach in waste water from paper mills. The most significant GM applications will be ones that help lessen the problem of agriculture , which accounts for 38percent of the world's landmass and is crowding out natural ecosystems and species habitats. Chances are, farmers will... Question: The reason accounting for the hesitation to accept the idea of the Enviropig is _ . Yes or no, is the answer "the moral concept"?
Ans: No

Article: Human wants seem endless, When a starving man gets a meal, he begins to think about an overcoat; when a manager gets a new sports car, he dreams of country clubs and pleasure boats dance into view. The many wants of mankind might be regarded as making up several levels. When there is money enough to satisfy one level of wants, another level appears. The first and most basic level of wants is food. Once this want is satisfied, a second level of wants appears: clothing and some sort of shelter. By the end of World War II these wants were satisfied for a great majority of Americans. Then a third level appeared. It included such items as cars and new houses. By 1957 or 1958 this third level of wants was fairly well satisfied. Then in the late 1950s a fourth level of wants appeared: the "life-enriching" level. While the other levels mean physical satisfaction--the feeding, comfort, safety and transportation of the human body--this level means mental needs for recognition, achievement and happiness, It includes a variety of goods and services many of which could be called "luxury" items. Among them are vacation trips, the best medical care and entertainment. Also included here are fancy foods and the latest styles in clothing. On the fourth level, a greater percentage of consumers spending goes to services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of wants as their income increases, or will they continue to demand luxuries and personal services on the fourth level? A fifth level probably would be wants that can be achieved by community action. Consumers may be spending more on taxes and crime. After filling our stomachs, our garages, and our minds, we now may seek to ensure the health and safety to enjoy more fully the good things on the first three levels. Question: The author thinks that a fifth level _ Yes or no, is the answer "may be a lot more desirable than the first four"?
No
