Food-as-Medicine Movement Is Witnessing Progress

查看长篇阅读全文翻译与逐题定位 →

) Several times a month, you can find a doctor in the aisles of Ralph's 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 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 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."
) 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 center's '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.
) Nadeau notices the pre-made macaroni(通心粉)-and-cheese boxes in Scott's shopping cart and suggests she switch to whole grain macaroni and real cheese. "So I'd 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. "I'm not sure they'd eat it. They just won't eat it."
) 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. "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.
) Nadeau is part of a small revolution developing across California. The food-as-medicine movement has been around for decades, but it's 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 are trying to prevent, limit or even reverse disease by changing what patients eat. "There's no question people can take things a long way toward reversing diabetes, reversing high blood pressure, even preventing cancer by food choices," Nadeau says.
) 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 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 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 hospital's medical director of Healthy Food Initiatives. "We want people to understand what they're eating, how to prepare it, the role food plays in their lives."
) 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 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 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 nation's 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 consumption of fruits and vegetables.
) "It's 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 prevent 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.
) Many people don't 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 teaching people about which foods are healthy and how to prepare them, she says, can actually transform a patient's life. And beyond that, it might transform the health and lives of that patient's 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."
) 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 — particularly for people with diabetes or other inflammatory conditions.
) "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."

Section C

Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C), and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.

Passage One

查看 Passage 1 全文翻译与详细解析 →

California has been facing a drought for many years now, with certain areas even having to pump freshwater hundreds of miles to their distribution system. The problem is 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 extracted (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 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 is 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 from these depths is expensive, it is still cheaper than desalinating (脱盐) the ocean water in the largely coastal state. Some desalination plants exist where feasible, but they are costly to run and can need constant repairs. Wells are much more reliable sources of freshwater, and California is hoping that these deep wells may be the answer to their severe water shortage.

One problem with these sources is that the deep water also has a higher level of salt than shallower aquifers. This means that some wells may even need to undergo desalination after extraction, thus increasing the cost. Research from the exhaustive study of groundwater from over 950 drilling logs has just been published. New estimates of the water reserves now go up to 2,700 billion cubic meters of freshwater.

46. How could California's drought crisis be solved according to some researchers?
A) By building more reserves of groundwater.
B) By drawing water from the depths of the earth.
C) By developing more advanced drilling devices.

Passage Two

查看 Passage 2 全文翻译与详细解析 →

The AlphaGo program's victory is an example of how smart computers have become.

But can artificial intelligence (AI) machines act ethically, meaning can they be honest and fair? One example of AI is driverless cars. They are already on California roads, so it is not too soon to ask whether we can program a machine to act ethically. As driverless cars improve, they will save lives. They will make fewer mistakes than human drivers do. Sometimes, however, they will face a choice between lives. Should the cars be programmed to avoid hitting a child running across the road, even if that will put their passengers at risk? What about making a sudden turn to avoid a dog? What if the only risk is damage to the car itself, not to the passengers?

Perhaps there will be lessons to learn from driverless cars, but they are not super-intelligent beings. Teaching ethics to a machine even more intelligent than we are will be the bigger challenge.

About the same time as AlphaGo's triumph, Microsoft's 'chatbot' took a bad turn. The software, named Taylor, was designed to answer messages from people aged 18-24. Taylor was supposed to be able to learn from the messages she received. She was designed to slowly improve her ability to handle conversations, but some people were teaching Taylor racist ideas. When she started saying nice things about Hitler, Microsoft turned her off and deleted her ugliest messages.

AlphaGo's victory and Taylor's defeat happened at about the same time. This should be a warning to us. It is one thing to use AI within a game with clear rules and clear goals. It is something very different to use AI in the real world. The unpredictability of the real world may bring to the surface a troubling software problem.

Eric Schmidt is one of the bosses of Google, which owns AlphoGo. He thinks AI will be positive for humans. He said people will be the winner, whatever the outcome. Advances in AI will make human beings smarter, more able and "just better human beings."

51. What does the author want to show with the example of AlphaGo's victory?
A) Computers will prevail over human beings.
B) Computers have unmatched potential.
C) Computers are man's potential rivals.
D) Computers can become highly intelligent.
