Questions 26 to 35 are based on the following passage. A third of the planet's land is severely degraded and fertile soil is being lost at the rate of 24th tonners a year, according to a new United Nations-backed study that calls for a shift away from destructively intensive agriculture, The alarming _26_, which is forecast to continue as demand for food and productive land increases, will ass to the risks of conflicts unless _27_ actions are implemented, warns the institution behind the report. "As the ready supply of healthy and productive land dries up and the population grows, competition is _28_ for land within countries and globally,"said executive secretary of the UN Convention to Combat Desertification(UNCCD) at the launch of the Global Land Outlook.“To _29_ the losses, the outlook suggests it is in all our interests to step back and rethink how we are managing the pressures and the competition." The Global Land Outlook is _30_ as the most comprehensive study of its type, mapping the interlinked impacts of urbanization, climate change, erosion and forest loss. But the biggest factor is the _31_ of industrial farming. Heavy tilling, multiple harvests ans _32_ use of agrochemicals have increased yields at the _33_ of long-term sustainability. If the past 20 years, agricultural production has increased threefold and the amount of irrigated land has doubled, notes a paper in the outlook by the Joint Research Centre(JRC) of the European commission. Over time, however, this _34_ fertility and can lead to abandomment of land and _35_ desertification.

Some children on the remote islands won’t eat their meals because they are fed cheap junk food.[A] Fazila is a young woman that has been dealing with eczema （湿疹）, a common skin condition, for the past five years, but never got it treated. The nearest hospital is an hour away, by boat and bus, and her skin condition didn't seem serious enough to make the trek, so she ignored it—until a new technology brought the doctor to her. Fazila lives on one of the remote river islands in northern Bangladesh. These islands are low-lying, temporary sand islands that are continuously formed and destroyed through sand buildup and erosion. They are home to over six million people, who face repeated displacement from flooding and erosion—which may be getting worse because of climate change—and a range of health risks, including poor nutrition, malaria (疟疾) and other water-borne diseases.[B] The most dangerous thing for these remote island dwellers is land erosion. The second is lack of access to medical supplies and doctors. There are no doctors within miles, and while child mortality and maternal death have gone down in the rest of the country, this is not the case for the islands. The medical situation is so bad that it really takes away from the quality of their life. Yet for many island inhabitants—some of Bangladesh’s poorest—paying for health care is a costly ordeal. Victims of erosion lose their houses, agricultural land and jobs as farmers, fishermen and day laborers. Though government hospitals are free, many people hesitate to go, citing long commutes, endless lines and questionable diagnoses. For convenience’s sake, one-third of rural households visit unqualified village doctors, who rely on unscientific methods of treatment, according to a 2016 study in the peer-reviewed journal Global Health Action.[C] On the islands, there's even a colloquial (口头的) expression for the idea of making medical care your lowest priority: It’s known as “rog pushai rakha” in Bengali, which roughly translates to “stockpiling their diseases”—waiting to seek medical attention until a condition becomes extremely serious. Now, a new virtual medical service called Teledaktar (TD) is trying to make health care more easily accessible. Every week, TD’s medical operators travel to the islands by boat, carrying a laptop, a portable printer for prescriptions and tools to run basic medical screenings such as blood pressure, blood sugar, body temperature and weight. They choose an area of the island with the best Internet reception and set up a makeshift（临时凑合的) medical center which consists of plastic stools and small tables borrowed from the locals’ homes, a tent in case of rain and a sheet that is strung up to give the patients privacy during their session.[D] Launched in October 2018, TD has eight centers in towns and villages across rural Bangladesh and on three islands. It is funded by a nonprofit organization founded by Bangladeshi entrepreneurs, finance and technology professionals. Inside the center, the laptop screen lights up to reveal Dr. Tina Mustahid, TD’s head physician, live-streamed (网络直播)from the capital city of Dhaka for free remote medical consultations. Affectionately called Doctor Apa—“older sister” in Bengali—by her patients, she is one of three volunteer doctors at TD.[E] “I diagnose them through conversation,” says Dr. Mustahid. “Sometimes it’s really obvious things that local doctors don’t have the patience to talk through with their patients. For example, a common complaint mothers come in with is that their children refuse to eat their meals. The mothers are concerned they are dealing with indigestion, but it’s because they are feeding the children packaged chips which are cheap and convenient. I tell them it is ruining their appetite and ask them to cut back on unhealthy snacks.” Dr. Mustahid says building awareness about health and nutrition is important for island patients who are cut off from mainland resources.请选择和题干内容相一致的段落。A、[A]B、[B]C、[C]D、[D]E、[E]

Do you ever blend up a protein drink for breakfast, or grab a protein bar following an afternoon workout? If so, you are likely among the millions of people in search of more protein-rich diets.Protein-enriched products are found everywhere. But contrary to all the publicity that everyone needs more protein, most Americans get twice as much as they need.Many of us living in the most developed countries are buying into a myth of protein deficiency created by food companies and self-identified health experts. Global retail sales of protein supplement products reached an astonishing US18.9 billion in 2020.But are we really in need of more protein? Physicians in the U.S. have never actually examined a patient with protein deficiency because simply by eating an adequate number of daily calories we are also most likely getting enough protein.In fact, Americans currently consume almost twice the National Academy of Medicine's recommended daily intake of protein although the most desirable protein intake may vary depending on age and activity level.For example, if you're a dedicated athlete you might need to consume higher quantities of protein. Generally, though, a 140-pound person should not exceed 120 grams of protein per day, particularly because a high protein diet can strain kidney and liver function and increase risks of developing heart disease and cancer.While fats and sugar have taken the beating in turns since over a century ago, protein has managed to remain our red-hot favorite.In the 1970s through the 1990s, protein products remained visible but moved back somewhat with the dietary spotlight firmly fixed on low-calorie, low-fat, sugar-free snack foods and beverages following the publication of studies linking sugar and saturated (饱和的) fat consumption to heart disease.Later research in 2003, however, suggested high-protein diets could aid in weight loss, and protein quickly regained its former nutrient-superstar status.Now most people living in high-income nations are consuming enough protein. When we replace meals with a protein bar or drink, we also risk missing out on the rich sources of antioxidants (抗氧化剂), vitamins and many other benefits of real food.51. What do we learn about publicity over protein in America?A) It has helped to create the myth of protein deficiency.B) It has helped Americans in search of protein-rich diets.C) It has raised a lot of health concerns among the public.D) It has been funded by food companies and health experts.52. Why have physicians in the U.S. never actually examined a patient with protein deficiency?A) Americans can purchase many kinds of protein-rich foods everywhere.B) Americans can absorb the number of calories recommended by food experts.C) Americans can get sufficient protein just by eating adequate foods daily.D) Americans can rely on food supplements to prevent protein deficiency.53. What should people take into consideration in deciding on the most preferable protein intake?A) How healthy they are and what food they eat.B) How old they are and what activities they do.C) How much protein they consume and what their body weight is.D) How serious their protein deficiency is and what remedies they use.54. What foods have been largely out of favor for more than a century?A) Sugar-free snacks.B) Protein-rich foods.C) Both red and white meats.D) Sugary and fatty foods.55. What does the author imply people in developed countries should do to keep healthy?A) Enjoy natural food.B) Eat vegetarian diets.C) Consume enough protein daily.D) Replace meals with protein bars.
