Air pollution costs the global economy more than $5 trillion annually in welfare costs, with the

17、 most serious【C1】 occurring in the developing world.The figures include a number of costs【C2】 with air pollution. Lost income alone amounts to $225 billion a year.The report includes both indoor and outdoor air pollution. Indoor pollution, which includes【C3】 like home heating and cooking, has remain

Levels of outdoor pollution have grown rapidly along with rapid growth in industry and transportation.Director of Institute for Health Metrics and Evaluation Chris Murray 【C5】 it as an “urgent call to action.”“One of the risk factors

On one recent day, this docto

24、r was Daniel Nadeau, wandering the cereal aisle with Allison Scott, giving her some idea on how to feed kids who persistently avoid anything that is healthy. “Have you thought about trying fresh juices in the morning?” he asks her. “The frozen oranges and apples are a little cheaper, and fruits are

25、really good for the brain. Juices are quick and easy to prepare, you can take the frozen fruit out the night before and have it ready the next morning.”B Scott is delighted to get food advice from a physician who is program director of the nearby Mary and Dick Allen Diabetes Center, part of the St.

26、Joseph Hoag Health alliance. The centers Shop with Your Doc program sends doctors to the grocery store to meet with any patients who sign up for the service, plus any other shoppers who happen to be around with questions.C Nadeau notices the pre-made macaroni (通心粉)-and-cheese boxes in Scotts shoppin

27、g cart and suggests she switch to whole grain macaroni and real cheese. “So Id have to make it?”she asks, her enthusiasm fading at the thought of how long that might take, just to have her kids reject it. “Im not sure theyd eat it. They just wont eat it.”D Nadeau says sugar and processed foods are b

28、ig contributors to the rising diabetes rates among children. “In America, over 50 percent of our food is processed food,” Nadeau tells her. “And only 5 percent of our food is plant-based food. I think we should try to reverse that.” Scott agrees to try more fruit juices for the kids and to make real

29、 macaroni and cheese. Score one point for the doctor, zero for diabetes.E Nadeau is part of a small revolution developing across California. The food-as-medicine movement has been around for decades, but its making progress as physicians and medical institutions make food a formal part of treatment,

30、 rather than relying solely on medications (药物). By prescribing nutritional changes or launching programs such as Shop with your Doc, they are trying to prevent, limit or even reverse disease by changing what patients eat. “Theres no question people can take things a long way toward reversing diabet

31、es, reversing high blood pressure, even preventing cancer by food choices,” Nadeau says.F In the big picture, says Dr. Richard Afable, CEO and president of ST. Joseph Hoag Health, medical institutions across the state are starting to make a philosophical switch to becoming a health organization, not

32、 just a health care organization. That feeling echoes the beliefs of the Therapeutic Food Pantry program at Zuckerberg San Francisco General Hospital, which completed its pilot phase and is about to expand on an ongoing basis to five clinic sites throughout the city. The program will offer patients

33、several bags of food prescribed for their condition, along with intensive training in how to cook it. “We really want to link food and medicine, and not just give away food,” says Dr. Rita Nguyen, the hospitals medical director of Healthy Food Initiatives. “We want people to understand what theyre e

34、ating, how to prepare it, the role food plays in their lives.”G In Southern California, Loma Linda University School of Medicine is offering specialized training for its resident physicians in Lifestyle Medicine that is a formal specialty in using food to treat disease. Research findings increasingl

35、y show the power of food to treat or reverse diseases, but that does not mean that diet alone is always the solution, or that every illness can benefit substantially from dietary changes. Nonetheless, physicians say that they look at the collective data and a clear picture emerges: that the salt, su

36、gar, fat and processed foods in the American diet contribute to the nations high rates of obesity, diabetes and heart disease. According to the World Health Organization, 80 percent of deaths from heart disease and stroke are caused by high blood pressure, tobacco use, elevated cholesterol and low c

37、onsumption of fruits and vegetables.H “Its a different paradigm(范式) of how to treat disease,” says Dr. Brenda Rea, who helps run the family and preventive medicine residency program at Loma Linda University School of Medicine. The lifestyle medicine specialty is designed to train doctors in how to p

38、revent and treat disease, in part, by changing patients nutritional habits. The medical center and school at Loma Linda also has a food cupboard and kitchen for patients. This way, patients not only learn about which foods to buy, but also how to prepare them at home.I Many people dont know how to c

39、ook, Rea says, and they only know how to heat things up. That means depending on packaged food with high salt and sugar content. So teaching people about which foods are healthy and how to prepare them, she says, can actually transform a patients life. And beyond that, it might transform the health

40、and lives of that patients family. “What people eat can be medicine or poison,” Rea says. “As a physician, nutrition is one of the most powerful things you can change to reverse the effects of long-term disease.”J Studies have explored evidence that dietary changes can slow inflammation(炎症), for exa

41、mple, or make the body inhospitable to cancer cells. In general, many lifestyle medicine physicians recommend a plant-based diet particularly for people with diabetes or other inflammatory conditions.K “As what happened with tobacco, this will require a cultural shift, but that can happen,” says Ngu

42、yen. “In the same way physicians used to smoke, and then stopped smoking and were able to talk to patients about it, I think physicians can have a bigger voice in it.”（分数：71.0）(1).More than half of the food Americans eat is factory-produced.（分数：7.1）A.B.C.D.E.F.G.H.I.J.K.(2).There is a special progra

The problem is

47、 growing as the population of the state continues to expand. New research has found deep water reserves under the state which could help solve their drought crisis. Previous drilling of wells could only reach depths of 1,000 feet, but due to new pumping practices, water deeper than this can now be e

48、xtracted (抽取). The team at Stanford investigated the aquifers(地下蓄水层)below this depth and found that reserves may be triple what was previously thought.It is profitable to drill to depths more than 1,000 feet for oil and gas extraction, but only recently in California has it become profitable to pump

49、 water from this depth. The aquifers range from 1,000 to 3,000 feet below the ground, which means that pumping will be expensive and there are other concerns. The biggest concern of pumping out water from this deep in the gradual settling down of the land surface. As the water is pumped out, the vacant space left is compacted by the weight of the earth above.Even though pumping
