2018年12月大学英语四级真题听力原文(第一套)来源：文都教育News 1A device that weighs less than one kilogram is part of a mission that will allow scientists to deliver fourth generation or 4G mobile coverage to the moon in 2019. If successful, the tiny device will provide the moon with its first ever mobile phone network. The lunar network will support high definition streaming of video and data between the moon and earth. The network is part of a mission to the moon. This is a project with the goal of landing the first privately paid for mission to the moon. The 4G mission is set to launch from Cape Canaveral in the United States on a space X Falcon 9 rocket in 2019. Mission to the moon intends to establish and test the first elements of a communications network on the moon. The scientists working on the project opted to build a 4G rather than a fifth generation or 5G network. This is because fifth generation networks are still in testing and trial phases. This means that a 5G network may not yet be stable enough to work on the mo on’s surface.Question 1: What are scientists planning to do?Question 2: Why did scientists choose to set up a 4G network in their mission?News 2It’s responded to a fire Wednesday night at an abandoned mall in Heywood. The fire was reported at 9:26 pm at an old shopping center on Michigan Avenue near St. Mary’s Church. Six fire engines, two trucks and two chiefs responded to the scene. Crews had the fire under control in about 45 minutes and managed to contain the fire to its point of origin. There were some people inside the building when the fire broke out but there were no reports of any injuries. Fire investigators have responded to the scene but have not yet determined the cause of the fire. Firefighters will remain on the scene until later this m orning to ensure that the fire doesn’t start up again. The shopping mall had not been in use since 2002. In 2014 City Hall developed a plan to knock down the building and replace it with affordable housing. However the plan was dropped due to lack of funds.Question 3: What does the news item say about the fire?Question 4: What had City Hall planned to do?News 3Potato chips in Japan are being sold for 6X their normal price. This is after the country’s main manufacturer stopped sales due to a potato shortage. Storms and floods and its main potato growing region last year caused the worst harvest and more than 3 decades. Local media reports suggest Calbee and its main rival Koike-ya are halting almost 50 products.“We don’t know when we’ll be able to restart”, a company spokesman said. Snack lovers are panic buying and many supermarket shelves are bare. Japanese laws limit the amount of importedpotatoes that can be used in Japanese made products. Japan says fear of disease is its main reason to block fresh imports. It still only allows potatoes from selected US states. This is only at certain times and on condition that they are processed at factories based near Japanese ports.But global warming has raised the possibility that domestic produce could be seriously affected by rare weather events more often.Question 5: What problem is Japan facing?Question 6: Why does Japan limit the import of potatoes?Question 7: What might affect Japanese domestic produce?Conversation 1M: Mr. Brown’s lectures are so boring.W: Yes, he is not a very exciting speaker. But the subject is interesting.M: During every one of his lectures, I try to listen I really try. But after about 10 minutes my mind begins to wander and I lose concentration. But I see that you seem to be OK. How do you stay focused through the entire hour?W: Well, what I do is keep my pen moving.M: What do you mean?W: It’s a method of active concentration I read about. One of the most effective ways to concentrate is to write things down. But it has to be done by hand, not typing on a keyboard. You see writing by hand forces you to actually engage with what you’re learning in a more physical way.M: Do you review your notes afterwards then?W: Sometimes but that’s not important. My notes may or may not be useful but the point is that by writing down what Mr. Brand says I can follow his line of thinking more easily. In fact, sometimes I draw a little too.M: You draw in class and that helps me pay attention?W: Yes, honestly it works for me. I just draw little lines and nonsense really. It was also in that article I read. It can keep the mind active, prevent getting bored and help to concentrate. Again the point is to listen hard while keeping the pen moving. If I’m at home and I need to study what I d o is read out loud. It has a similar effect to writing by hand. It helps memorize information in a physical way.Question 8: What does the man think of Mr. Brown’s lectures?Question 9: What does the woman do during Mr. Brown’s lectures?Question 10: Why does the woman draw in class?Question 11: What does the woman say about reading out loud?Conversation 2M: And where is this?F: These photos are from the Taj Mahal in India. We went there about ten years ago for our honeymoon.M: Was it romantic.F: Yeah. The Taj Mahal was a very romantic place. The guide told us there is a famous love story behind this building that all Indians learn in school. I think it was during the 1600 and the princess at that time died while giving birth to her 14th child. The Emperor loved the princess so much and was so sad when she died that he ordered the palace to be built in her honor.M: Wow! That sounds very romantic. It looks amazing.F: Yes it’s gorgeous. It’s also larger in real life than it looks in the photos. The building is very tall and there are gardens in a wall around it all. It’s all built in this white stone and some walls of the building are decorated with jewels.M: It must have been very crowded when you were there.F: Yes it’s a very famous tourist dest ination. So there are thousands of visitors every day.M: Was the rest of India crowded?F: Yes, very crowded in many cities. It was sometimes so crowded that it was difficult to walk along the streets especially through busy markets. And there are so many cars. Traffic was terrible but the people were friendly. The culture is amazing and we had a great time.M: What about the food?F: the Indian food is great. There are lots of different dishes to try and every region has its own special food.Question 12: For what purpose did the woman go to India?Question 13: Why was the Taj Mahal built?Question 14: What does the woman say about the Taj Mahal?Question 15: W hat is the woman‘s impression of Indian cities?Passage 1A Pew Research Center survey of more than 1000 Americans conducted in April 2016 finds that Americans continue to express largely positive views about the current state of their local public libraries. For instance around three quarters say that public libraries provide them with the resources they need and 66 percent say the closing of their local public library would have a major impact on their community. Although notably just 33 percent say this would have a major impact on them personally or on their family. A majority of Americans feel libraries are doing a good job of providing a safe place for people to hang out or spend time as well as opening up educational opportunities for people of all ages and roughly half think their libraries contribute a lot to their communities in terms of helping spark creativity among young people and providing a trusted place for people to learn about new technologies. As in past Pew Research Center surveys of library use the April 2016 survey also measured Americans usage of and engagement with libraries. Overall, 53 percent of Americans ages 16 and older have had some interaction with the puppet library in the past year either through an in person visit or using a library Web site some 48percent of adults specifically visited a library in the past 12 months. A modest increase from the 44 percent who said that in late 2015.Question 16: What do most Americans say about local public libraries?Question 17: How can local public libraries benefit young people?Question 18：What does the 2016 survey show about adult library users?Passage 2A Savannah cat is a crossbreed between a domestic cat and a medium-sized wild African cat called the Serval. The unusual cross became popular among breeders at the end of the 1990s. And in 2001, the International Cat Association accepted it as a new registered breed. The savannahs are tall and slim and can weigh up to nine point one kilograms, making them one of the largest breeds of cats that people can own. They have a spotted code similar to that of many types of wild cats and their ears are very large. They are also commonly compared to dogs in their loyalty and can be trained to walk on a lead and to fetch, and often noted characteristic of the Savannah is its jumping ability. They are known to jump on top of doors and high cabinets. Some can leap about 2.5 metres high from a standing position. Cats are typically known for being very inquisitive and so are the Savannahs. They often learn how to open doors and cupboards. Many Savannah cats do not fear water and will play with or even dive into water. Some owners even shower with their Savannah Cats, presenting a water bowl to Savannah may also prove a challenge, as some will promptly begin to bat all the water out of the bowl until it is empty using their front paws.Question 19: What do we learn about the savannah cat?Question 20: What is characteristic of Savannah cats?Question 21: What do some people do with their Savannah cats?Passage 3When children start school for the very 1st time parents often feel a sense of excitement coupled with a touch of sadness at the end of an era. This is the start of a new adventure for children playing and interacting with new friends sharing, taking turns and settling into a new routine.But of course, this is not the start of yo ur child’s education which in fact began at birth. Back then, yo u would have been your child’s most influential teachers. During this time at home, your child would have learnt more than at any other period in their life. During your child’s first year in school much time will be spent in learning to read and they need to know that this is fun and worthwhile. Your child will naturally copy you so it is important that you are seen reading and enjoying books newspapers and magazines rather than just absorbed in screens. Ultimately an excellent education should be a close partnership between parents and teachers. A child’s year splits fairly neatly into thirds: a 3rd at school, a 3rd asleep and a third awake at home or on holiday.Irrespective of the quality of a school a child‘s home life is of key importance. It is thedetermining factor of their academic success. Your child may have started on a new journey but your work is far from finished.Question 22: How do parents feel when their children start going to school?Question 23: What does the passage say about children’s education?Question 24: What should parents do for the success of their children’s education?Question 25: What does the passage say is the key factor of loinbo’s academic success?。

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 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 ideas 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.”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 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.C) 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 sur e they’d eat it. They just won’t 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. “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. 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 Do’, 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.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 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.”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 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.H)”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.I) 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 s ays. “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 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.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 healthy breakfast can be prepared quickly and easily.40. Training a patient to prepare healthy food can change their life.41.One food-as-medicine program net only prescribes food for treatment but teaches patients how to cook it.42. Scott is not keen on cooking food herself, thinking it would simply be a waste of time.43. Diabetes patients are advised to eat more plant-based food.44. Using food as medicine is no novel idea, but the movement is making headway these days.45. Americans’ high rates of various illnesses result from the way they eat.Section CDirections: 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 OneQuestions 46 to 50 are based on the following passage.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 investigatedthe 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.D) By upgrading its water distribution system.47.What can be inferred about extracting water from deep aquifers?A) It was deemed vital to solving the water problem.B) It was not considered worth the expense.C) It may not provide quality freshwater.D) It is bound to gain support from the local people.48.What is mentioned as a consequence of extracting water from deep underground?A)The sinking of land surface.B) The harm to the ecosystem.C) The damage to aquifers.D) The change of the climate.49.What does the author say about deep wells?A) They run without any need for repairs.C) They are the ultimate solution to droughtsB) They are entirely free from pollutants.D)They provide a steady supply of freshwater.50.What may happen when deep aquifers are used as water sources?A) People’s health may improve with cleaner water.B) People’s water bills may be lowered considerably.C) The cost may go up due to desalination.D) They may be exhausted sooner or later.Passage TwoQuestions 51 to 55 are based on the following passage.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 抑^ 识出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 live. 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, 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 AlphaGo. 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 sm arter, 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.52.What does the author mean by AI machines acting ethically?A) They are capable of predicting possible risks.B) They weigh the gains and losses before reaching 及decision.C) They make sensible decisions when facing moral dilemmas.D) They sacrifice everything to save human lives.53.

Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.Questions 26 to 35 are based on the following passage.Millions die early from air pollution each year. 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 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. 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 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 problem 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.Section 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. Identify 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 Progress[A] 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 kid s 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.”[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 Heal th 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.[C] 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.”[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. “And only 5 percent of our foo d 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 docto r, 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 it’s making progress as physicians and medical institutions make food a formal part of treatment, rather than relying sol ely on medications (药物). By prescribing nutritional ch anges 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 reversin g diabetes, reversing high blood pressu re, 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 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 prepar e 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 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 contrib ute 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.[H] “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 als o 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 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 e at can be medicine or poison,” Rea says. “As a physician, nutrition is one o f 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 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.[K] “As what happened with tobacco, this will require a cultural shift, but that can happen,” says Nguyen. “In the same way p hysicians used to smoke, and then stopped smoking and were able to talk to patients about it, I think physicians can have a bigger voic e 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 healthy breakfast can be prepared quickly and easily.40. Training a patient to prepare healthy food can change their life.41. One food-as-medicine program not only prescribes food for treatment but teaches patients how to cook it.42. Scott is not keen on cooking food herself, thinking it would simply be a waste of time.43. Diabetes patients are advised to eat more plant-based food.44. Using food as medicine is no novel idea, but the movement is making headway these days.45. Americans’ high rates of various illnesses result from the way they eat. Section CDirections: 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 OneQuestions 46 and 50 are based on the following passage.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 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 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.D) By upgrading its water distribution system.47.What can be inferred about extracting water from deep aquifers?A) It was deemed vital to solving the water problem.B) It was not considered worth the expense.C) It may not provide quality freshwater.D) It is bound to gain support from the local people.48. What is mentioned as a consequence of extracting water from deep underground?A) The sinking of land surface. C) The damage to aquifers.B) The harm to the ecosystem. D) The change of the climate.49. What does the author say about deep wells?A) They run without any need for repairs.B) They are entirely free from pollutants.C) They are the ultimate solution to droughts.D) They provide a steady supply of freshwater.50. What may happen when deep aquifers are used as water sources?A) People’s health may improve with cleaner water.B) People’s water bills may be lowered considerably.C) The cost may go up due to desalination.D) They may be exhausted sooner or later.Passage TwoQuestions 51 to 55 are based on the following passage.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 thatwill 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 on e 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 own 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 wit h 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.52.What does the author mean by AI machines acting ethically?A)They are capable of predicting possible risks.B)They weigh the gains and losses before reaching a decision.C)They make sensible decisions when facing moral dilemmas.D)They sacrifice everything to save human lives.53.What is said to be the bigger challenge facing humans in the AI age?A)How to make super-intelligent AI machines share human feelings.B)How to ensure that super-intelligent AI machines act ethically.C)How to prevent AI machines doing harm to humans.D)How to avoid being over-dependent on AI machines.54.What do we learn about Microsoft’s “chatbot” Taylor?A)She could not distinguish good from bad.B)She could turn herself off when necessary.C)She was not made to handle novel situations.D)She was good at performing routine tasks.55. What does Eric Schmidt think of artificial intelligence?A) It will be far superior to human beings.B) It will keep improving as time goes by.C) It will prove to be an asset to human beings.D) It will be here to stay whatever the outcome.Part Ⅳ Translation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

Although studying abroad is often praised by people for its advantages, there are still some disadvantages to be noticed.First of all, to study abroad is expensive. Specifically speaking, those involved have to spend a large amount of money on tuition and living expenses, which is not affordable for everyone. In addition, to study abroad is a great challenge for those students who lack the ability of living independently. If they can not take good care of themselves there, their academic performance will be affected to a large extent. Last but not least, to study abroad may exercise a negative influence on students’ mentality. As we all know, to study abroad equals to stay away from family and friends for a long time, which is likely to produce some psychological problems for those students, such as being solitary and gloomy.From what has been mentioned above, we can easily come to the conclusion that the disadvantages of studying abroad can not be neglected. What’s more, those students who are planning to study abroad should make enough preparations for these problems mentioned above. Only in this way, can they have a fruitful and successful study life abroad.【参考译文】众所周知，随着经济的蓬勃发展和家庭收入的增加，出国留学已经成为越来越受学生欢迎的选择。

You may not use any of the words in the bank more than once.Millions die early from air pollution each year. 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 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. 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 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 problem 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) abilityB) associatedC) consciouslyD) constantE) controlF) damageG) describedH) equals I) exclusively J) innovated K) regularly L) relates M) sources N) undermine O) vehiclesSection 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. Identify 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 MovementIs Witnessing ProgressA) 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.”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 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.C) 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.”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. “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. Thefood-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.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 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 fo od and medicine, and not just give away food,” says Dr. Rita Nguyen, the hospital’s medical director of HealthyFood Initiatives. “We want people to understand what they’re eating, 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 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.H) “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.I) 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.”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 – particularly for people with diabetes or other inflammatory conditions.K) “As what happened with tobacco, this will require a cultural s hift, 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 healthy breakfast can be prepared quickly and easily.40. Training a patient to prepare healthy food can change their life.41. One food-as-medicine program not only prescribes food for treatment but teaches patients how to cook it.42. Scott is not keen on cooking food herself, thinking it would simply be a waste of time.43. Diabetes patients are advised to eat more plant-based food.44. Using food as medicine is no novel idea, but the movement is making headway these days.45. Americans’ high rates of various illnesses result from the way the y eat.Section CDirections: 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 OneQuestions 46 to 50 are based on the following passage.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 desalinationplants 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.D) By upgrading its water distribution system.47. What can be inferred about extracting water from deep aquifers?A) It was deemed vital to solving the water problem.B) It was not considered worth the expense.C) It may not provide quality freshwater.D) It is bound to gain support from the local people.48. What is mentioned as a consequence of extracting water from deep underground?A) The sinking of land surface.B) The harm to the ecosystem.C) The damage to aquifers.D) The change of the climate.49. What does the author say about deep wells?A) They run without any need for repairsB) They are entirely free from pollutants.C) They are the ultimate solution to droughtsD) They provide a steady supply of freshwater.50. What may happen when deep aquifers are used as water sources?A) People’s health may improve with cleaner water.B) People’s water bills may be lowered considerably.C) The cost may go up due to desalination.D) They may be exhausted sooner or later.Passage TwoQuestions 51 to 55 are based on the following passage.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 Alpha Go’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 warming 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 AlphaGo. 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. Wha t 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.52. What does the author mean by AI machines acting ethically?A) They are capable of predicting possible risks.B) They weigh the gains and losses before reaching a decision.C) They make sensible decisions when facing moral dilemmas.D) They sacrifice everything to save human lives.63. What is said to be the bigger challenge facing humans in the AI age?A) How to make super-intelligent AI machines share human feelings.B) How to ensure that super-intelligent AI machines act ethically.C) How to prevent AI machines doing harm to humans.D) How to avoid being over-dependent on AI machines.54. What do we learn about Microsoft’s “chatbot” Taylor?A) She could not distinguish good from bad.B) She could turn herself off when necessary.C) She was not made to handle novel situations.D) She was good at performing routine tasks.55. What does Eric Schmidt think of artificial intelligence?A) It will be far superior to human beings.B) It will keep improving as time goes by.C) It will prove to be an asset to human beings.D) It will be here to stay whatever the outcome.Part IV TranslationDirections: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

写作范文：On the Relationship between Doctors and PatientsIn the present age, it is generally acknowledged that the relationship between doctors and patients is playing indispensable roles in our lives. As far as I am concerned, we should balance this kind of relationship from two aspects, doctors and patients.The causes of this perspective are multiple. In the first place, the reason has been cited as amajor reason that doctors cannot be understood, for patients always maintain doctors can cure all kinds of disease. This is mainly due to the fact that although medical technology and science are advanced at an amazing rate, there exists a multitude of various kinds of diseases we cannot cure. Furthermore, the reason can contribute this perspective that patients are believed to be lack of the fundamental medical knowledge, which results in this relationship are worried. Plenty of evidence has shown that an increasing number of patients often go to extremes if their diseases cannot be cure instantly.When it comes to our modern society, it is universally acknowledged that dealing with the relationship between doctors and patients in a reasonable way plays a vitally important role in our lives.

参考原文：A device that weighs less than 1 kilogram is part of a mission that will allow scientists to deliver fourth generation or 4G mobile coverage to the moon in 2019. If successful, the tiny device will provide the moon with its first ever mobile phone network. The lunar network will support high definition streaming of video and data between the moon and the earth. The network is part of a mission to the moon. This is a project with the goal of landing the first privately paid for mission to the moon. The 4G mission is set to launch from Cape Canaveral in the United States on a space X Falcon Nine Rocket in 2019. Mission to the moon intends to establish and test the first elements of a communications network on the moon. The scientists working on the project opted to build 4G rather than the fifth generation or 5G work. This is because fifth generation networks are still in testing and trial phases. This means that a 5G network may not yet be stable enough to work on the moon’s surface.Question 1. What are scientists planning to do?Question 2. Why did scientists choose to set up a 4G network in their mission?解析：本篇新闻难度适中,第一题类似主旨题,问到了科学家的计划,在新闻导语第一句即给出了本篇新闻的主旨内容，即在月球上安置一个可支持4G的设备。

Answer the questions by marking the corresponding letter on Answer Sheet 2.Food-as-Medicine Movement Is Witnessing Progress[A] 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.”[B] Scott is delighted to get food advice from a physician whois 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.[C] 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.”[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. “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. The food-as-medicine movement has been aroundfor 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.[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 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 wantpeople to understand what they’re eating, 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 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.[H] “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, bychanging 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 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.”[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 —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 Nguyen. “In thesame 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 healthy breakfast can be prepared quickly and easily.40. Training a patient to prepare healthy food can change their life.41. One food-as-medicine program not only prescribes food for treatment but teaches patients how to cook it.42. Scott is not keen on cooking food herself, thinking it would simply be a waste of time.43. Diabetes patients are advised to eat more plant-based food.44. Using food as medicine is no novel idea, but the movement is making headway these days.45. Americans’high rates of various illnesses result from theway they eat.Section CDirections: 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 OneQuestions 46 to 50 are based on the following passage.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 oiland 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 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 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.D) By upgrading its water distribution system.47.What can be inferred about extracting water from deep aquifers?A) It was deemed vital to solving the water problem.B) It was not considered worth the expense.C) It may not provide quality freshwater.D) It is bound to gain support from the local people.48. What is mentioned as a consequence of extracting water from deep underground？A) The sinking of land surface. C) The damage to aquifers.B) The harm to the ecosystem. D) The change of the climate.49. What does the author say about deep wells?A) They run without any need for repairs.B) They are entirely free from pollutants.C) They are the ultimate solution to droughts.D) They provide a steady supply of freshwater.50. What may happen when deep aquifers are used as water sources?A) People’s health may improve with cleaner water.B) People’s water bills may be lowered considerably.C) The cost may go up due to desalination.D) They may be exhausted sooner or later.Passage TwoQuestions 51 to 55 are based on the following passage.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 own AlphoGo. He thinks AI will be positive for humans. He said people will be the winner, whatever the outcome. Advances inAI 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.52.What does the author mean by AI machines acting ethically?A)They are capable of predicting possible risks.B)They weigh the gains and losses before reaching a decision.C)They make sensible decisions when facing moral dilemmas.D)They sacrifice everything to save human lives.53.What is said to be the bigger challenge facing humans in the AI age?A)How to make super-intelligent AI machines share human feelings.B)How to ensure that super-intelligent AI machines act ethically.C)How to prevent AI machines doing harm to humans.D)How to avoid being over-dependent on AI machines.54.What do we learn about Microsoft’s ‘chatbot’Taylor?A)She could not distinguish good from bad.B)She could turn herself off when necessary.C)She was not made to handle novel situations.D)She was good at performing routine tasks.55. What does Eric Schmidt think of artificial intelligence?A) It will be far superior to human beings.B) It will keep improving as time goes by.C) It will prove to be an asset to human beings.D) It will be here to stay whatever the outcome.Part ⅣTranslation (30 minutes) Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

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 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 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 sourcesof 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.

New estimates of the water reserves now go up to 2,700 billion cubic meters of freshwater.could California’s drought crisis be solved according to some researchersA) By building more reserves of groundwater.B) By drawing water from the depths of the earth.C) By developing more advanced drilling devices.D) By upgrading its water distribution system.can be inferred about extracting water from deep aquifersA) It was deemed vital to solving the water problem.B) It was not considered worth the expense.C) It may not provide quality freshwater.D) It is bound to gain support from the local people.48. What is mentioned as a consequence of extracting water from deep undergroundA) The sinking of land surface. C) The damage to aquifers.B) The harm to the ecosystem. D) The change of the climate.49. What does the author say about deep wellsA) They run without any need for repairs.B) They are entirely free from pollutants.C) They are the ultimate solution to droughts.D) They provide a steady supply of freshwater.50. What may happen when deep aquifers are used as water sourcesA) People’s health may improve with cleaner water.B) People’s water bills may be lowered considerably.C) The cost may go up due to desalination.D) They may be exhausted sooner or later.Passage TwoQuestions 51 to 55 are based on the following passage.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 fairOne 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 passengersPerhaps there will be lessons to learn from driverless cars, but theyare 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 own 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 victoryA) Computers will prevail over human beings.B) Computers have unmatched potential.C) Computers are man’s potential rivals.D) Computers can become highly intelligent.52. What does the author mean by AI machines acting ethicallyA) They are capable of predicting possible risks.B) They weigh the gains and losses before reaching a decision.C) They make sensible decisions when facing moral dilemmas.D) They sacrifice everything to save human lives.53. What is said to be the bigger challenge facing humans in the AI ageA) How to make super-intelligent AI machines share human feelings.B) How to ensure that super-intelligent AI machines act ethically.C) How to prevent AI machines doing harm to humans.D) How to avoid being over-dependent on AI machines.54. What do we learn about Microsoft’s ‘chatbot’ TaylorA) She could not distinguish good from bad.B) She could turn herself off when necessary.C) She was not made to handle novel situations.D) She was good at performing routine tasks.55. What does Eric Schmidt think of artificial intelligenceA) It will be far superior to human beings.B) It will keep improving as time goes by.C) It will prove to be an asset to human beings.D) It will be here to stay whatever the outcome.Part Ⅳ Translation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

【2018年12月四级试卷一参考答案】【听力参考原文】News 1A device that weighs less than one kilogram is part of a mission that will allow scientists to deliver fourth generation or 4G mobile coverage to the moon in 2019. If successful, the tiny device will provide the moon with its first ever mobile phone network. The lunar network will support high definition streaming of video and data between the moon and earth. The network is part of a mission to the moon. This is a project with the goal of landing the first privately paid for mission to the moon. The 4G mission is set to launch from Cape Canaveral in the United States on a space X Falcon 9 rocket in 2019. Mission to the moon intends to establish and test the first elements of a communications network on the moon. The scientists working on the project opted to build a 4G rather than a fifth generation or 5G network. This is because fifth generation networks are still in testing and trial phases. This means that a 5G network may not yet be stable enough to work on the moon‘s surfaceQuestion 1：What are scientists planning to do？Question 2：Why did scientists choose to set up a 4G network in their mission？一个重量不到一公斤的设备是一项任务的一部分，该任务将允许科学家在2019年向月球提供第四代或4G移动覆盖。

Potato chips in Japan are being sold for 6X their normal price. This is after the country‘s main manufacturer stopped sales due to a potato shortage. Storms and floods and its main potato growing region last year caused the worst harvest and more than 3 decades. Local media reports suggest Calbee and its main rival Koike-ya are halting almost 50 products.“We don‘t know when we’ll be able to restart”, a company spokesman said. Sna ck lovers are panic buying and many supermarket shelves are bare. Japanese laws limit the amount of imported potatoes that can be used in Japanese made products. Japan says fear of disease is its main reason to block fresh imports. It still only allows potatoes from selected US states. This is only at certain times and on condition that they are processed at factories based near Japanese ports.But global warming has raised the possibility that domestic produce could be seriously affected by rare weather events more often.Question 5：What problem is Japan facing？Question 6：Why does Japan limit the import of potatoes？Question 7：What might affect Japanese domestic produce？在日本，薯片的售价是正常价格的6倍。
