Air pollution costs the global economy more than $5 trillion annually in welfare costs, with the most serious 26 occurring in the developing world.The figures
22、 include a number of costs 27 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 28 like home heating and cooking, has remained 29 over the past several decades despite advances in the area.
23、 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 30 it as an “urgent call to action.”“One of the risk factors for premature deaths is the air we breathe, over which individuals
24、have little 31 ,”he said.The effects of air pollution are worst in the developing world, where in some places lost-labor income 32 nearly 1% of GDP. Around 9 in 10 people in low-and middle-income countries live in places where they 33 experience dangerous levels of outdoor air pollution.But the prob
25、lem is not limited 34 to the developing world. Thousands die prematurely in the U.S. as a result of related illnesses. In many European countries, where diesel(柴油) 35 have become more common in recent years, that number reaches tens of thousands.A) ability K) regularlyB) associated L) relatesC) cons
26、ciously M) sourcesD) constant N) undermineE) control O) vehiclesF) damageG) describedH) equalsI) exclusivelyJ) innovatedSection BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identi
27、fy the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2. Food-as-Medicine Movement Is Witnessing ProgressA Several times a month, you can find
28、 a doctor in the aisles of Ralphs market in Huntington Beach, California, wearing a white coat and helping people learn about food. On one recent day, this doctor was Daniel Nadeau, wandering the cereal aisle with Allison Scott, giving her some idea on how to feed kids who persistently avoid anythin
29、g 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 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 n
30、ext 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. Joseph Hoag Health alliance. The centers Shop with Your Doc program sends doctors to the grocery store to meet with any patients who sign u
31、p 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 shopping 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 thou
32、ght 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 big contributors to the rising diabetes rates among children. “In America, over 50 percent of our food is processed food,” Nadeau tells her.
33、 “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 macaroni and cheese. Score one point for the doctor, zero for diabetes.E Nadeau is part of a small revolution developing across California
34、. 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, rather than relying solely on medications (药物). By prescribing nutritional changes or launching programs such as Shop with your Doc, they
35、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 diabetes, reversing high blood pressure, even preventing cancer by food choices,” Nadeau says.F In the big picture, says Dr. Richard Afable, CEO
36、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 just a health care organization. That feeling echoes the beliefs of the Therapeutic Food Pantry program at Zuckerberg San Francisco Genera
37、l 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 several bags of food prescribed for their condition, along with intensive training in how to cook it. “We really want to link food and medi
38、cine, 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 eating, how to prepare it, the role food plays in their lives.”G In Southern California, Loma Linda University School of Medicine is offerin
39、g specialized training for its resident physicians in Lifestyle Medicine that is a formal specialty in using food to treat disease. Research findings increasingly 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
40、 can benefit substantially from dietary changes. Nonetheless, physicians say that they look at the collective data and a clear picture emerges: that the salt, sugar, fat and processed foods in the American diet contribute to the nations high rates of obesity, diabetes and heart disease. According to
41、 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 consumption 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
42、 and preventive medicine residency program at Loma Linda University School of Medicine. The lifestyle medicine specialty is designed to train doctors in how to prevent and treat disease, in part, by changing patients nutritional habits. The medical center and school at Loma Linda also has a food cup
43、board 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 cook, Rea says, and they only know how to heat things up. That means depending on packaged food with high salt and sugar content. So teachin
44、g 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 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 pow
45、erful 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 example, or make the body inhospitable to cancer cells. In general, many lifestyle medicine physicians recommend a plant-based diet particular
46、ly 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 Nguyen. “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.”36. More than half of the food Americans eat is factory-produced.37. There is a special program that assigns doctors to give advice to shoppers in food stores.38. There is growing evidence from research that food helps patients recover from various illnesses.39. A
