2018年12月大学英语六级第三套真题及答案
2018年12月大学英语六级考试真题及参考答案 Part I Writing (30 minutes) For this part， you are allowed 30 minutes to write an essay on how to balance academic study and extracurricular activities. You should write at least 150 words but no more than 200 words。
Part Ⅲ Reading Comprehension (40 minutes) Section A Directions: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. 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.
In what’s probably the craziest headline I’ve ever written, I’ve reported that 26 in livestock protection are happening with scientists painting eyes on the butts of cows. The experiment is based upon the idea that farmers who’re protecting their herd from lions would shoot and kill lions in an effort to protect their livestock. While this makes a lot of sense, it results in many lion deaths that 27 would have been unnecessary. Researchers in Australia have been 28 and testing a method of trickery to make lions think they are being watched by the painted eyes on cow butts.
This idea is based on the principle that lions and other 29 are far less likely to attack when they feel they are being watched. As conservation areas become smaller, lions are increasingly coming into contact with human populations, which are expanding to the 30 of these protected areas.
Efforts like painting eyes on cow butts may seem crazy at first, but they could make actual headway in the fight for conservation. “If the method works, it could provide farmers in Botswana-and 31 —with a low-cost, sustainable tool to protect their livestock, and a way to keep lions safe from being killed.”
Lions are 32 ambush（埋伏）hunters, so when they feel their prey has 33 them, they usually give up on the hunt. Researchers are 34 testing their idea on a select herd of cattle. They have painted half of the cows with eyes and left the other half as normal. Through satellite tracking of both the herd and the lions in the area, they will be able to 35 if their psychological trickery will work to help keep farmers from shooting lions. Section B Directions: 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. Resilience Is About How You Recharge, Not How You Endure
[A] As constant travelers and parents of a 2-year-old, we sometimes fantasize about how much work we can do when one of us gets on a plane, undistracted by phones, friends, or movies. We race to get all our ground work done: packing, going through security, doing a last-minute work call, calling each other, then boarding the plane. Then, when we try to have that amazing work session in flight, we get nothing done. Even worse, after refreshing our email or reading the same
studies over and over, we are too exhausted when we land to soldier on with（继续处理） the emails that have inevitably still piled up.
[B] why should flying deplete us? We’re just sitting there doing nothing. Why can’t we be tougher, more resilient（有复原力的） and determined in our work so we can accomplish all of the goals we set for ourselves? Based on our current research, we have come to realize that the problem is not our hectic schedule or the plane travel itself; the problem comes from a misconception of what it means to be resilient, and the resulting impact of overworking.
[C] We often take a militaristic, “tough” approach to resilience and determination like a Marine pulling himself through the mud, a boxer going one more round, or a football player picking himself up off the ground for one more play. We believe that the longer we tough it out, the tougher we are, and therefore the more successful we will be. However, this entire conception is scientifically inaccurate.
[D] The very lack of a recovery period is dramatically holding back our collective ability to be resilient and successful. Research has found that there is a direct correlation between lack of recovery and increased incidence of health and safety problems. And lack of recovery —whether

Part ill Reading Comprehension (40 minutes) Section ADirections: In this section, there is a passage with ten blanks. Yo u are required to select one word for each blank from a list of choices given in a word bank following the passage.Read the passage through carefully before making your choices.Each choice in the bank is ident加d by a letter: Please mark the corresponding letter for each item on Answer Sheet2 with a single line through the centre. Yo u may not use any of the words in the bank more than once.A few months ago, I was down with a terrible cold which ended in a persistent bad cough. No matter how many different 26 I tried, I still couldn't get rid of the cough. Not only did it 27 my teaching but also my life as a whole. Then one day after class, a student came up to me and 28 traditional Chinese medicine. From her description, Chinese medicine sounded as if it had magic power that worked wonders. I was 29 because I knew so little about it and have never tried it before. Eventually, my cough got so much 30 that I couldn't sleep at night, so I decided to give it a try. The Chinese doctor took my pulse and asked to see my tongue, both of which were new 31 to me because they are both non-existent in Western medicine. Then the doctor gave me a scraping (刮）treatment known as "Gua Sha". I was a little 32 at first because he used a smooth edged tool to scrape the skin on my neck and shoulders. A few minutes later, the 33 strokes started to produce a relieving effect and my body and mind began to 34 deeper into relaxation. I didn't feel any improvement in my condition in the first couple of days, but after a few more regular visits to the doctor, my cough started to 35 . Then, within a matter of weeks, it was completely gone!A)deepen B) e xperiences C)hesitantD)" mconvemence E) l essen F) l icensesG) p ressured H) r ecommended!)remediesJ) s cared K) s ensitive L) s inkM) t emporary N)tremble O)worseSection 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. I dentify the paragraph from which the information i.s 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.Is it really OK to eat food that's fallen on the floor?A) W hen you drop a piece of food on the floor, is it really OK to eat if you pick it up within five seconds? An urban food myth contends that if food spends just a few seconds on the floor, dirt and germs won't have much of a chance to contaminate it. Research in my lab has focused on how food becomes contaminated, and we've done some work on this particular piece of wisdom.B)W怕le the "five-second rule" might not seem like the most pressing issue for food scientists to get to the bottom of, it's still worth investigating food myths like this one because they shape our beliefs about when food is safe to eat.C) S o is five seconds on the floor the critical threshold (门槛）that separates a piece of eatable food from a case of food poisoning? It's a bit more complicated than that. It depends on just how many bacteria can make it from floor to food in a few seconds and just how dirty the floor is.D) W ondering if food is still OK to eat after it's dropped on the floor is a pretty common experience. And it's probably not a new one either. A well-known, but inaccurate, story about Julia Child may have contributed to this food myth. Some viewers of her cooking show, The French Chef, insist they saw Child drop lamb on the floor and pick it up, with the advice that if they were alone in the kitchen, their guests would never know.E) I n fact it was a potato pancake, and it fell on the stovetop, not on the floor. Child put it back in the pan, saying, "But you can always pick it up and if you're alone in the kitchen, who's going to see it?" But the misremembered story persists. It's harder to pin down the origins of the oft-quoted five-second rule, but a 2003 study reported that 70% of women and 56% of men surveyed were familiar with the five-second rule and that women were more likely than men to eat food that had dropped on the floor.F) S o what does science tell us about what a few moments on the floor means for the safety of you food? The earliest research report on the five-second rule is attributed to Jillian Clarke, a high school student participating in aresearch project at the University of Illinois.Clarke and her colleagues introduced bacteria to floor tiles (瓷砖）and then placed cookies on the tiles for varying times. They reported bacteria were transferred from the tiles to the cookies within five seconds, but didn't report the specific amount of bacteria that made it from the tiles to the food.G)But how many bacteria actually transfer in five seconds? In 2007, my lab at Clemson University published a study in the Journal of Applied Microbiology. We wanted to know if the length of time food is in contact with a contaminated surface affected the rate of transfer of bacteria to the food. To find out, we introduced bacteria to squares of tile, carpet or wood.Five minutes after that, we placed either bacon or bread on the surface for 5, 30 or 60 seconds, and then measured the number of bacteria transferred to the food. W e repeated this exact procedure after the bacteria had been on the surface for 2, 4, 8 and 24 hoursH) W e found that the number of bacteria transferred to either kind of food didn't depend much on how long the food was in contact with the contaminated surface—whether for a few seconds or for a whole minute. The overall number of bacteria on the surface mattered more, and this decreased over time after the initial introduction. It looks like what's at issue is less how long your food stays on the floor and much more how contaminated with bacteria that patch of floor happens to be.I) W e also found that the kind of surface made a difference as well. Carpets, for instance, seem to be slightly better places to drop your food than wood or tile. When a carpet was contaminated, less than 1 %of the bacteria were transferred.But when the food was in contact with tile or wood, 48-70% of bacteria were.J) L ast year, a study from Aston University in the UK used nearly identical parameters (参数）to our study and found similar results. They also reported that 87 %of people asked either would eat or had eaten food fallen on the floor. K) Should you eat food fallen on the floor then? From a food safety standpoint, if you have millions or more bacteria on a surface, 0.1 %is still enough to make you sick. Also, certain types of bacteria are extremely harmful, and it takes only a small number to make you sick. For example, 10 bacteria or less of an especially deadly strain of bacteria can cause severe illness and death in people with compromised immune systems. B ut the chance of these bacteria being on most surfaces is very low.L) A nd it's not just dropping food on the floor that can lead to bacterial contamination.Bacteria are carried by various "media", which can include raw food, moist surfaces where bacteria have been left, our hands or skin and from coughing or sneezing (打喷咙）. Hands, foods and utensils (器皿）can carry individual bacteria living in communities contained within a protective film. These microscopic layers of deposits containing bacteria are known as biofilms and they are found on most surfaces and objects. Biofilm communities can harbor bacteria longer and are very difficult to clean. Becteria in these communities also have an enhanced resistance to sanit也ers(清洁剂）and antibiotics compared to bacteria living on their own.M) S o the next time you consider eating fallen food, the odds are in your favor that you can eat it without getting sick. But in the rare chance that there is a micro-organism that can make you sick on the exact spot where the food dropped, you can be fairly sure that the bug is on the food you are about to put in your mouth.N) R esearch or common sense tells us that the best thing to do is keep your hands, utensils and other surfaces clean.36.A research project found bacteria made their way to the food on the floor in five seconds.37. W hether food is contaminated depends much on the number of bacteria that get onto it.38.Food contamination may result from various factors other than food dropping on the floor.39.Males are less likely than females to eat food that may have been contaminated.40. T he author's research centers around how food gets contaminated.41.Keeping everything clean is the best way to stay healthy.42.Chances are you will not fall sick because of eating food picked up from the floor.43.For a long time people have had the experience of deciding whether or not to eat food picked up from the floor.44.Some strains of bacteria are so harmful that a tiny few can have deadly consequences.45.Researchers found how many bacteria got onto the food did not have much to do with how long the food stayed ona contaminated floor.Section CDirections: There are 2 passages in this section. E ach passage is followed by some questions or unfinished statements. Fo r each of them there are four choices marked A), B), C) a nd D). Yo u should decide on the best choice and markthe corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.The latest in cat research reveals that the lovely animal seems to have a basic grasp on both the laws of physics and the ins and outs of cause and effect.According to a newly published study, cats seem to be able to predict the location of hiding prey (猎物）using both their ears and an inborn(天生的）understanding of how the physical world works.In a recent experiment, Japanese researchers taped 30 domestic cats reacting to a container that a te皿member shook. S ome containers rattled (发出响声）；others did not. W hen the con血ner tipped over, sometimes an object fell out and sometimes it didn't.It turns out that the cats were remarkably smart about what would happen when a container was tipped over. When an object did not drop out of the bottom of a rattling container, they looked at it for a longer time than they did when the container behaved as expected."Cats use a causal-logical understanding of noise or sounds to predict the appearance of invisible objects," lead researcher Saho Takagi says in a press release. T he researchers conclude that cats'hunting style may have developed based on their common-sense abilities to infer where prey is, using their hearing.Scientists have explored this idea with other endearing creatures: babies. L ike cats, babies appear to engage in what's called "preferential looking"—looking longer at things that are interesting or unusual than things they perceiveas normal.When babies'expectations are violated in experiments like the ones performed with the cats, they react much like their animal friends.Psychologists have shown that babies apparently expect their world to comply with the laws of physics and cause and effect as early as two months of age.Does the study mean that cats will soon grasp the ins and outs of cause and effect? Maybe. Okay, s o cats may not be the next physics faculty members at America's most important research universities. But by demonstrating their common sense, they've shown that the divide between cats and humans may not be that great after all.46. What do we learn from a newly published study about cats?A) They can be trained to understand the physical world.B) They know what kind of prey might be easier to hunt.C) They have a natural ability to locate animals they hunt.D) They are capable of telling which way their prey flees.47.What may account for the cats'response to the noise from the containers?A) Their inborn sensitivity to noise.C) Their special ability to perceive. B) Their unusual sense of direction.D) Their mastery of cause and effect.48. W hat is characteristic of the way cats hunt, according to the Japanese researchers?A) They depend on their instincts.C) They wait some time before attack.49.In what way do babies behave like cats?A) They focus on what appears odd.C) They do what they prefer to do.50. W hat can we conclude about cats from the passage?A) They have higher intelligence than many other animals.B) They interact with the physical world much like humans.C) They display extraordinarily high intelligence in hunting.D) They can aid physics professors in their research work.Passage TwoQuestions 51 to 55 are based on the following passage. B) They rely mainly on their hearing.D) They use both their ears and eyes.B) They view the world as normal. D) They are curious about everything.Imagine you enter a car with no steering wheel, no brake or accelerator pedals (踏板）. Under a voice-activated command, you say an address. "The fastest route will take us 15.3 minutes. Should I take it?" You say "yes" and you are on your way. T he car responds and starts moving all by itself. All you have to do is sit back and relax.How weird would it be if, one day in the future, everyone had such a car? No crazy driving, no insults, no cutting in; traffic laws would be respected and driving much safer. O n the other hand, imagine the cost savings for local police enforcement and town budgets without all those speeding and parking tickets.A new technology has the potential to change modem society in radical ways.There's no question that self-driving vehicles could be an enormous benefit. T he potential for safer cars means accident statistics would drop: some 94% of road accidents in the U.S. involve human error. Older drivers and visually-or physically-impaired people would gain a new level of freedom. Maintaining safe speeds and being electric, self-driving cars would drastically reduce pollution levels and dependency on non-renewable fuels.Roads would be quieter, people safer.But we must also consider the impact of the new technology on those who now depend on driving for their livelihoods. According to the U.S. Department of Labor, in May 2015 there were 505, 660 registered school bus drivers. T he American Trucking Association lists approximately 3.5 million professional truck drivers in the U.S ..The companies developing self-driving vehicles should be partnering with state and federal authorities to offerretraining for this massive workforce, many of whom will be displaced by the new technology. This is similar to what's happening in the coal and oil industries, a situation that fuels much of the current political discontent in this country.New technologies will, and should, be developed. T his is how society moves forward. However, progress can't be one-sided. It is necessary for the companies and state agencies involved to consider the ethical consequences of these potential changes to build a better future for all.61. W hat would be the impact of the extensive use of driverless cars?A) People would be driving in a more civilized way.B) It would save local governments a lot of money.C) More policemen would be patrolling the streets.D) Traffic regulations would be a thing of the past.52.How would the elderly and the disabled benefit from driverless cars?A) They could enjoy greater mobility.C) They would have no trouble driving.B) They would suffer no road accidents.D) They could go anywhere they want.53.What would be the negative impact of driverless cars?A) The conflict between labor and management would intensify.B) The gap between various sectors of society would be widened.C) Professional drivers would have a hard time adapting to new road conditions.D)Numerous professional drivers would have to find new ways of earning a living.54. W hat is the result of the introduction of new technologies in energy industries?A)Political dissatisfaction.C) Fossil fuel conservation.B) Retraining of employees.D) Business restructuring.55.What does the author suggest businesses and the government do?A)Keep pace with technological developments.B) Make new technologies affordable to everyone.C) Enable everyone to benefit from new technologies.D) Popularize the use of new technologies and devicesPart IV Translation (30 minutes) Directions: For t如s part, you are allowed 30 minutes to translate a passage from Chinese into English. You should write your answer on Answer Sheet 2.过去几年里，移动支付市场在中国蓬勃发展。

I think it promises enrichment for any reader from those who know little about science to the career physicist.A: And it‘s refreshing to see a strong curious clever woman adding her voice to the scientific discourse and a field that has been traditionally dominated by men. I think she has to be commended for making an effort to include anecdotes about little known female scientists. You know they were often victims of a generation firmly convinced that the woman’s place was in the home.B: I like how the book is clearly written with each chapter brought to life by pieces of fascinating knowledge. For example in one chapter she exposes a myth that I‘ve heard taught by university physics professors. I’ve often heard that medieval glass windows are thicker at the bottom because glass flowslike a fluid. This, she shows, is not true. The distortion is actually thanks to a peculiarity of the glassmakers process.A: Yeah I like how she cultivates scientific engagement by providing a host of Do It Yourself experiments that bring the same foundational principles of classical physics that govern everything from the solar system to your kitchen table. From using complex laws of physics to test whether a spinning egg is cooked to measuring atmospheric pressure by lifting a piece of cardboard. Her hands-on examples make her book a truly interactive read.B: Yes, I must say this, a equation-free book is an ideal read for scientists of all stripes, anyone teaching science and even people who dislike physics.Question 1:What does the woman say about the book the man recommended?Question 2: What can we find in the book the man recommended?Question 3:How does the author bring her book to life? Question 4: How does the book cultivate readers interest in physics.Conversation 2A:Hi professor. I was hoping I could have a moment of your time if you‘re not too busy. I’m having some problems getting started on my dissertation and I was hoping you could give me some advice on how to begin.B:Sure. I have quite a few students though.So can you remind me what your topic is?A:The general topic I chose is aesthetics, but that‘s as far as I’ve got I don‘t really know where to go from there.B:Yeah, that‘s much too large a topic. You really need to narrow it down in order to make it more accessible. Otherwise you’ll be writing a book.A:Exactly. That‘s what I wanted to ask you about. I was hoping it would be possible for me to change topics. I’m really more interested in nature than beauty.B:I‘m afraid you have to adhere to the assigned topic. Still, If you’re interested in nature, then that certainly can be worked into your dissertation. We‘ve talked about Hume before in class right.A:Oh yeah, he‘s the philosopher who wrote about where our ideas of beauty come from.B:Exactly. I suggest you go to the library and get a copy of his biography. Start from there. But remember to stick to the parameters of the assignment. This paper is a large part of your cumulative grade. So make sure to follow the instructions. If you take a look at his biography. You can get a good idea of how his life experiences manifest themselves in his theories of beauty, specifically the way he looked towards nature as the origin of what we find beautiful.A:Great. Thanks for taking the time to answer my questions, Professor. I‘ll let you get back to class now.B:If there‘s anything else you need, please come see me in my office any time.Question 5: What is the man‘s problem?Question 6: What does the professor think of the man‘s topic? Question 7: What’s the man really more interested in? Question 8: What does the professor say the man has to do? Passage 1During the arctic winter from October to March, the average temperature in the frozen north typically hovers around minus 20 degrees Celsius. But this year the Arctic is experiencing much higher temperatures. On February the 20th the temperature inGreenland climbed above freezing or zero degrees Celsius and it stayed there for over 24 hours. Then on February the 24th the temperature on Greenland‘s northern tip reached six degrees Celsius. Climate scientists describe the phenomenon as stunning. Weather conditions that drive this bizarre temperature surge have visited the Arctic before. They typically appear about once in a decade. However, the last such increase in temperature took place two years ago. This is troubling as climbing arctic temperatures combined with rapid sea ice loss are creating a new type of climate feedback loop which could accelerate Arctic warming. Indeed, sea ice cover in the Arctic is melting faster than expected. Without those masses of cooling sea ice, warm air brought to the Arctic can penetrate further inland than it ever did before. The air can stay warmer longer too. This drives additional melting. Overall earth is warming at a rapid pace. 2014 through 2017 rank as the hottest years on record and the Arctic is warming twice as fast as any place else on earth. This raises unique challenges for Arctic wildlife and indigenous people who depend on Arctic ecosystems to survive. Previously climate forecasts predicted that Arctic summer ice would disappear entirely by around 2060, but based on whatscientists are seeing now the Arctic may be facing summers without ice within 20 years.Question 9: What did climate scientists describe as stunning? Question 10: What does the passage say about that temperature surge in the Arctic?Question 11: What may occur in 20 years according to scientists’recent observations?Passage 2A good dose of willpower is often necessary to see any task through whether it‘s sticking to a spending plan or finishing a great novel. And if you want to increase that willpower. A new study suggests you just simply have to believe you have it. According to this study, what matters most is what we think about our willpower. If we believe it’s a finite resource, we act that way, we feel exhausted and need breaks between demanding mental tasks. However, people who view their willpower as a limitless resource get energized instead. The researchers used a psychological assessment tool to test the validity of the study. They asked 1100 Americans and 1600 Europeans to grade different statements such as after a challenging mental activity, my energy is depleted and I mustrest to get it refueled again or I can focus on a mental task for long periods without feeling tired.Although there was little difference between men and women overall. Americans were more likely to admit to needing breaks after completing mentally challenging tasks European participants on the other hand claimed they were able to keep going. Based on the findings, the researchers suggest that the key to boosting your willpower is to believe that you have an abundant supply of it. Your feelings about your willpower affect the way you behave. But these feelings are changeable, they said. Changing your beliefs about the nature of your self-control can have positive effects on character development. This leads to healthier behaviors and perceptions of other people.Question 12: What is often necessary for carrying through a task?Question 13: What is the finding of the new study?Question 14: What do we learn about European participants as compared with their American counterparts?Question 15: What do the research say concerning people‘s feelings about willpower?Lecture 1Here is my baby niece Sarah. Her mum is a doctor and her dad is a lawyer. By the time Sarah goes to college the jobs her parents do are going to look dramatically different. In 2013, researchers at Oxford University did a study on the future of work.They concluded that almost one in every two jobs has a high risk of being automated by machines. Machine learning is the technology that‘s responsible for most of this disruption. It’s the most powerful branch of artificial intelligence. It allows machines to learn from data and copy some of the things that humans can do. My company, Kaggle, operates on the cutting edge of machine learning. We bring together hundreds of thousands of experts to solve important problems for industry and academia. This gives us an unique perspective on what machines can do, what they can‘t do and what jobs they might automate or threaten. Machine learning started making its way into industry in the early 90s. It started with relatively simple tasks. It started with things like assessing credit risk from loan applications, sorting the mail by reading handwritten zip codes. Over the past few years, we have made dramatic breakthroughs. Machine learning is now capable of far, far more complex tasks. In 2012, Kaggle challenged its community to build a programthat could grade high school essays. The winning programs were able to match the grades given by human teachers. Now given the right data, machines are going to outperform humans at tasks like this. A teacher might read 10000 essays over a 40-year career. A machine can read millions of essays within minutes. We have no chance of competing against machines on frequent high-volume tasks, but there are things we can do that machines cannot. Where machines have made very little progress is in tackling novel situations. Machines can’t handle things they haven‘t seen many times before. The fundamental limitation of machine learning is that it needs to learn from large volumes of past data. But humans don’t. We have the ability to connect seemingly different threads to solve problems we‘ve never seen before.Question 16. What did the researchers at Oxford University conclude?Question 17. What do we learn about Kaggle companies winning programs?Question 18. What is the fundamental limitation on machine learning?Lecture 2we‘ve talked recently about the importance of sustainable energy. We’ve also talked about the different theories on how that can be done. So far, our discussions have all been theoretical. Now I have a practical question for you all. Can you run a 140,000 kilogram train on just the steam generated by solar power? Well, one engineer, Tim Casselman, believes it‘s possible. And his home city of Sacramento, California should see the technology’s first test as part of the upgrading of its rail yard. Casselman, who is an inventor and self-proclaimed steam visionary, is campaigning for a new steam train that runs without any fire and could run on an existing 10 kilometer line drawing tourists and perhaps offering city commuters a green alternative to their cars. Casselman wants to build an array of solar magnifying mirrors at one end of the line to collect and focus heat onto water filled tubes. This would generate steam that could be used to fill tanks on a small steam train without the use of fire. Supplying power to trains in this way would offer the shortest distance from well to wheels he says with the least amount of energy lost. According to Harry Valentijn, a Canadian engineer who is researching modern steam technology, a special tank measuring 2 by 10 metres could store over 750 kilowatt hours of energy as high pressure steam enough to pulla two car train for an hour or so. Energy to drive a steam locomotive can be stored in other materials besides water, for example, a team at Tohoku University in Japan has studied materials that can store large amounts of heat when heated. These materials turn from a solid into a liquid absorbing energy as they change phase. The liquid is maintained above its melting point until steam is required at which point the liquid is allowed to turn back into a solid releasing its stored energy. Another team at Nagoya University in Japan has tested calcium compound as an energy storage material. Heating this chemical compound drives off carbon dioxide gas, leaving calcium oxide. The gas can be stored under pressure and attain to recover the energy. The gas is fed back over the calcium oxide. In theory, says Valentijn, this can create a high enough temperature to generate superheated steam.Question 19: What has the speaker previously talked about? Question 20: What is Tim Casselman trying to do in Sacramento? Question 21: What has a Japanese research team tried to do? Lecture 3Today‘s crisis in care for older people in England has two main causes.First,people are living longer with a lot more complex needs. Second, they rely on a system that has long been marked by a poor relation between national health and social-care services. Current services originate in two key measures. They are the National Health Service and the 1948 National Assistance Act. This required local government to provide residential accommodation for older people and supervise care homes run by independent organizations.They also provided home and community services including meals, day centers and home helpers and other subsidized services. The National Health Service was free and wholly publicly provided. It delivered the best health-care for all. No such vision guided residential and community care though. The care was substantially provided by voluntary services which worked together with local authorities as they long had with eligibility based on income. Today, life expectancy has risen from 66 for a male at birth in 1948 to around 80 now. In addition, there is better overall health and improved medical knowledge and care. This means an unprecedented number of people are surviving longer in conditions requiring expert support. Families provide at least as much care as they ever did. Even so,they can rarely without subsidised support address serious personal needs. Care for older people faced persistent criticism as these trends became apparent. From the early 1960s, local authorities were required to plan health and welfare services. The aim was to enable older people to remain in their own homes for as long as possible, but this increased concern about the lack of coordination between free health and paid-for social care. Through the 1970s, a number of measures sought to improve matter. However, at a time of financial crisis, funding diminished and little changed. In the 1980s, the government cut spending. Meanwhile, preference for private over public services made management even more difficult. Simultaneously, the number of sick older people grew. Governments emphasized the need to improve services. They did so though while doing little to stop the erosion of available aid. Services were irregular across authorities. Unless you were prepared to pay, they were increasingly difficult to obtain for any but the most severely disabled. Why has 60 years of criticism produced so little change? Discrimination against older people has a long history. Additionally, those affected by inadequate health and social care are too vulnerable to launch the protests that have addressed other forms of discrimination.Question 22: What is one cause of the current crisis in care for the elderly in England?Question 23: What does the speaker say about residential and community care?Question 24: What made management of care for the elderly more difficult in the 1980s?Question 25: What does the speaker say about older people in England?【听力真题答案】1-5：ABCDD6-10 :ABCAC11-15：BCDAB16-20：ADCDA21-25：BDACB1.

Section A几个月前，我因为患了重感冒病倒了，结果一直咳嗽得很厉害。
无论我尝试了多少种不同的[26]治疗方法，我仍然咳嗽不止。
这不仅给我的教学[27]带来了不便，也给我的整个生活造成了麻烦。
后来有一天下课后，一个学生过来向我[28]推荐中医。
从她的描述中，中医听起来似乎有种神奇的魔力，能创造奇迹。
我[29]犹豫不决，因为我对中医知之甚少，而且以前从未尝试过。
最后，我咳嗽得愈加[30]厉害，以至于晚上无法入睡，所以我决定试试中医。
中国医生给我把了脉，并要求查看了我的舌头，这些对我来说都是新的[31]体验，因为它们在西医中都是不存在的。
后来医生给我做了刮痧疗法。
起初我有点[32]害怕，因为他用一个边缘光滑的工具刮我脖子和肩膀上的皮肤。
几分钟后，[33]有力道的刮痧开始产生缓解作用，我的身心开始[34]陷入更深层的放松之中。
在最初的几天，我感觉身体状况没有任何好转，但是经过几次定期就诊后，我的咳嗽开始[35]缓解。
后来，在大约几个星期之内，咳嗽完全消失了！Section B掉在地上的食物真的可以吃吗？A)当你把一块食物掉在地上时，如果你在五秒内捡起来，真的就可以吃吗？城市中有一个关于食物的传言认为，如果食物在地板上只停留了几秒钟的时间，灰尘和细菌就不会有太多机会污染它。
[40]我的实验室的研究集中在食物是如何被污染的，我们在这一特殊的学问方面已经做了一些研究工作。
B)虽然“五秒钟规则”或许看上去并非食品科学家最迫切需要弄清楚的问题，但像这种关于食物的传言仍然值得研究，因为它们使我们形成了关于食物何时可以安全食用的看法。
C)那么，在地板上停留5秒钟是把一块可食用的食物和一起食物中毒案例区分开来的关键参数吗？事情比这要更加复杂一点。
[37]这取决于到底有多少细菌能在几秒钟内从地板附着到食物上面，以及地板有多脏。
D)[43]想知道食物掉在地上后是否还能吃是很多人都有过的经历。
而且，这很可能也不是什么新鲜事了。

Yo u are required to select one word for each blank from a list of choices given in a word bank following the passage.Read the passage through carefully before making your choices. Each choice in the bank is ident加d by a letter: Please mark the corresponding letter for each item on Answer Sheet2 with a single line through the centre. Yo u may not use any of the words in the bank more than once.A few months ago, I was down with a terrible cold which ended in a persistent bad cough. No matter how many different 26 I tried, I still couldn't get rid of the cough. Not only did it 27 my teaching but also my life as a whole. Then one day after class, a student came up to me and 28 traditional Chinese medicine. From her description, Chinese medicine sounded as if it had magic power that worked wonders. I was 29 because I knew so little about it and have never tried it before. Eventually, my cough got so much 30 that I couldn't sleep at night, so I decided to give it a try. The Chinese doctor took my pulse and asked to see my tongue, both of which were new 31 to me because they are both non-existent in Western medicine. Then the doctor gave me a scraping (刮）treatment known as "Gua Sha". I was a little 32 at first because he used a smooth edged tool to scrape the skin on my neck and shoulders. A few minutes later, the 33 strokes started to produce a relieving effect and my body and mind began to 34 deeper into relaxation. I didn't feel any improvement in my condition in the first couple of days, but after a few more regular visits to the doctor, my cough started to 35 .

Each statement contains information given in one of the paragraphs. I dentify the paragraph from which the information i.s 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.Is it really OK to eat food that's fallen on the floor?A) W hen you drop a piece of food on the floor, is it really OK to eat if you pick it up within five seconds? An urban food myth contends that if food spends just a few seconds on the floor, dirt and germs won't have much of a chance to contaminate it.Research in my lab has focused on how food becomes contaminated, and we've done some work on this particular piece of wisdom.B)W怕le the "five-second rule" might not seem like the most pressing issue for food scientists to get to the bottom of, it's still worth investigating food myths like this one because they shape our beliefs about when food is safe to eat.C) S o is five seconds on the floor the critical threshold (门槛）that separates a piece of eatable food from a case of food poisoning? It's a bit more complicated than that. It depends on just how many bacteria can make it from floor to food in a few seconds and just how dirty the floor is.D) W ondering if food is still OK to eat after it's dropped on the floor is a pretty common experience. And it's probably not a new one either. A well-known, but inaccurate, story about Julia Child may have contributed to this food myth. Some viewers of her cooking show, The French Chef, insist they saw Child drop lamb on the floor and pick it up, with the advice that if they were alone in the kitchen, their guests would never know.E) I n fact it was a potato pancake, and it fell on the stovetop, not on the floor. Child put it back in the pan, saying, "But you can always pick it up and if you're alone in the kitchen, who's going to see it?" But the misremembered story persists. It's harder to pin down the origins of the oft-quoted five-second rule, but a 2003 study reported that 70% of women and 56% of men surveyed were familiar with the five-second rule and that women were more likely than men to eat food that had dropped on the floor.F) S o what does science tell us about what a few moments on the floor means for the safety of you food? The earliest research report on the five-second rule is attributed to Jillian Clarke, a high school student participating in aresearch project at the University of Illinois.Clarke and her colleagues introduced bacteria to floor tiles (瓷砖）and then placed cookies on the tiles for varying times. They reported bacteria were transferred from the tiles to the cookies within five seconds, but didn't report the specific amount of bacteria that made it from the tiles to the food.G)But how many bacteria actually transfer in five seconds? In 2007, my lab at Clemson University published a study in the Journal of Applied Microbiology. We wanted to know if the length of time food is in contact with a contaminated surface affected the rate of transfer of bacteria to the food. To find out, we introduced bacteria to squares of tile, carpet or wood.Five minutes after that, we placed either bacon or bread on the surface for 5, 30 or 60 seconds, and then measured the number of bacteria transferred to the food. W e repeated this exact procedure after the bacteria had been on the surface for 2, 4, 8 and24 hoursH) W e found that the number of bacteria transferred to either kind of food didn't depend much on how long the food was in contact with the contaminated surface—whether for a few seconds or for a whole minute. The overall number of bacteria on the surface mattered more, and this decreased over time after the initial introduction. It looks like what's at issue is less how long your food stays on the floor and much more how contaminated with bacteria that patch of floor happens to be.I) W e also found that the kind of surface made a difference as well. Carpets, for instance, seem to be slightly better places to drop your food than wood or tile. When a carpet was contaminated, less than 1 %of the bacteria were transferred.But when the food was in contact with tile or wood, 48-70% of bacteria were.J) L ast year, a study from Aston University in the UK used nearly identical parameters (参数）to our study and found similar results. They also reported that 87 %of people asked either would eat or had eaten food fallen on the floor. K) Should you eat food fallen on the floor then? From a food safety standpoint, if you have millions or more bacteria on a surface, 0.1 %is still enough to make you sick. Also, certain types of bacteria are extremely harmful, and it takes only a small number to make you sick. For example, 10 bacteria or less of an especially deadly strain of bacteria can cause severe illness and death in people with compromised immune systems. B ut the chance of these bacteria being on most surfaces is very low.L) A nd it's not just dropping food on the floor that can lead to bacterial contamination.Bacteria are carried by various "media", which can include raw food, moist surfaces where bacteria have been left, our hands or skin and from coughing or sneezing (打喷咙）. Hands, foods and utensils (器⽫）can carry individual bacteria living in communities contained within a protective film. These microscopic layers of deposits containing bacteria are known as biofilms and they are found on most surfaces and objects. Biofilm communities can harbor bacteria longer and are very difficult to clean. Becteria in these communities also have an enhanced resistance to sanit也ers(清洁剂）and antibiotics compared to bacteria living on their own.M) S o the next time you consider eating fallen food, the odds are in your favor that you can eat it without getting sick. But in the rare chance that there is a micro-organism that can make you sick on the exact spot where the food dropped, you can be fairly sure that the bug is on the food you are about to put in your mouth.N) R esearch or common sense tells us that the best thing to do is keep your hands, utensils and other surfaces clean.36.A research project found bacteria made their way to the food on the floor in five seconds.37. W hether food is contaminated depends much on the number of bacteria that get onto it.38.Food contamination may result from various factors other than food dropping on the floor.39.Males are less likely than females to eat food that may have been contaminated.40. T he author's research centers around how food gets contaminated.41.Keeping everything clean is the best way to stay healthy.42.Chances are you will not fall sick because of eating food picked up from the floor.43.For a long time people have had the experience of deciding whether or not to eat food picked up from the floor.44.Some strains of bacteria are so harmful that a tiny few can have deadly consequences.45.Researchers found how many bacteria got onto the food did not have much to do with how long the food stayed ona contaminated floor.Section CDirections: There are 2 passages in this section. E ach passage is followed by some questions or unfinished statements. Fo r each of them there are four choices marked A), B), C) a nd D). Yo u should decide on the best choice and markthe corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.The latest in cat research reveals that the lovely animal seems to have a basic grasp on both the laws of physics and the ins and outs of cause and effect.According to a newly published study, cats seem to be able to predict the location of hiding prey (猎物）using both their ears and an inborn(天⽣的）understanding of how the physical world works.In a recent experiment, Japanese researchers taped 30 domestic cats reacting to a container that a te⽫member shook. S ome containers rattled (发出响声）；others did not. W hen the con⾎ner tipped over, sometimes an object fell out and sometimes it didn't.It turns out that the cats were remarkably smart about what would happen when a container was tipped over. When an object did not drop out of the bottom of a rattling container, they looked at it for a longer time than they did when the container behaved as expected."Cats use a causal-logical understanding of noise or sounds to predict the appearance of invisible objects," lead researcher Saho Takagi says in a press release. T he researchers conclude that cats'hunting style may have developed based on their common-sense abilities to infer where prey is, using their hearing.Scientists have explored this idea with other endearing creatures: babies. L ike cats, babies appear to engage in what's called "preferential looking"—looking longer at things that are interesting or unusual than things they perceiveas normal.When babies'expectations are violated in experiments like the ones performed with the cats, they react much like their animal friends.Psychologists have shown that babies apparently expect their world to comply with the laws of physics and cause and effect as early as two months of age.Does the study mean that cats will soon grasp the ins and outs of cause and effect? Maybe. Okay, s o cats may not be the next physics faculty members at America's most important research universities. But by demonstrating their common sense, they've shown that the divide between cats and humans may not be that great after all.46. What do we learn from a newly published study about cats?A) They can be trained to understand the physical world.B) They know what kind of prey might be easier to hunt.C) They have a natural ability to locate animals they hunt.D) They are capable of telling which way their prey flees.47.What may account for the cats'response to the noise from the containers?A) Their inborn sensitivity to noise.C) Their special ability to perceive. B) Their unusual sense of direction.D) Their mastery of cause and effect.48. W hat is characteristic of the way cats hunt, according to the Japanese researchers?A) They depend on their instincts.C) They wait some time before attack.49.In what way do babies behave like cats?A) They focus on what appears odd.C) They do what they prefer to do.50. W hat can we conclude about cats from the passage?A) They have higher intelligence than many other animals.B) They interact with the physical world much like humans.C) They display extraordinarily high intelligence in hunting.D) They can aid physics professors in their research work.Passage TwoQuestions 51 to 55 are based on the following passage. B) They rely mainly on their hearing.D) They use both their ears and eyes.B) They view the world as normal. D) They are curious about everything.Imagine you enter a car with no steering wheel, no brake or accelerator pedals (踏板）. Under a voice-activated command, you say an address. "The fastest route will take us 15.3 minutes. Should I take it?" You say "yes" and you are on your way. T he car responds and starts moving all by itself. All you have to do is sit back and relax.How weird would it be if, one day in the future, everyone had such a car? No crazy driving, no insults, no cutting in; traffic laws would be respected and driving much safer. O n the other hand, imagine the cost savings for local police enforcement and town budgets without all those speeding and parking tickets.A new technology has the potential to change modem society in radical ways.There's no question that self-driving vehicles could be an enormous benefit. T he potential for safer cars means accident statistics would drop: some 94% of road accidents in the U.S. involve human error. Older drivers and visually-or physically-impaired people would gain a new level of freedom. Maintaining safe speeds and being electric, self-driving cars would drastically reduce pollution levels and dependency on non-renewable fuels.Roads would be quieter, people safer.But we must also consider the impact of the new technology on those who now depend on driving for their livelihoods. According to the U.S. Department of Labor, in May 2015 there were 505, 660 registered school bus drivers. T he American Trucking Association lists approximately 3.5 million professional truck drivers in the U.S ..The companies developing self-driving vehicles should be partnering with state and federal authorities to offerretraining for this massive workforce, many of whom will be displaced by the new technology. This is similar to what's happening in the coal and oil industries, a situation that fuels much of the current political discontent in this country.New technologies will, and should, be developed. T his is how society moves forward. However, progress can't be one-sided. It is necessary for the companies and state agencies involved to consider the ethical consequences of these potential changes to build a better future for all.61. W hat would be the impact of the extensive use of driverless cars?A) People would be driving in a more civilized way.B) It would save local governments a lot of money.C) More policemen would be patrolling the streets.D) Traffic regulations would be a thing of the past.52.How would the elderly and the disabled benefit from driverless cars?A) They could enjoy greater mobility.C) They would have no trouble driving.B) They would suffer no road accidents.D) They could go anywhere they want.53.What would be the negative impact of driverless cars?A) The conflict between labor and management would intensify.B) The gap between various sectors of society would be widened.C) Professional drivers would have a hard time adapting to new road conditions.D)Numerous professional drivers would have to find new ways of earning a living.54. W hat is the result of the introduction of new technologies in energy industries?A)Political dissatisfaction.C) Fossil fuel conservation.B) Retraining of employees.D) Business restructuring.55.What does the author suggest businesses and the government do?A)Keep pace with technological developments.B) Make new technologies affordable to everyone.C) Enable everyone to benefit from new technologies.D) Popularize the use of new technologies and devicesPart IV Translation (30 minutes) Directions: For t如s part, you are allowed 30 minutes to translate a passage from Chinese into English.

You may not use any of the words in the bank more than once.Questions 26 to 35 are based on the following passage.Just off the coast of Southern California sits Santa Cruz Island, where a magical creature called the island fox 26 .A decade ago, this island’s ecosystem was in 27 . Wild pigs attracted golden eagles from the mainland, and those flying 28 crashed the fox population. So the Nature Conservancy launched a 29 war against the pigs, complete with helicopters and sharp shooters.And it worked. Today, federal agencies are pulling the island fox from the Endangered Species List. It’s the fastest-ever recovery of a mammal, joining peers like the Louisiana black bear as glowing successes in the history of theof invasive species here, from sheep to plants to the 31 Argentine ant. “Our philosophy with the island has always been, ‘OK, 32 the threats and let the island go back to what it was,’” says ecologist Christina Boser. And it appears to be working. Native plants are coming back, and the fox once again bounds about carefree.But keeping those foxes from harm will occupy Boser and her colleagues for years to come. You see, humans are still allowed on Santa Cruz Island, and they bring dogs. So Boser has to vaccinate her foxes against various diseases. “We’re obligated to keep a pulse on the population for at least five years after the foxes are delisted,” says Boser. That includes tagging the foxes and 33 their numbers to ensure nothing goes wrong.This is the story of the little fox that has come back, and the people who have 34 their lives to protecting it. This is the story of wildlife conservation in the age of mass 35 .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.

But after she snapped a photo and started using her phone, he asked her a serious question:“Are you going to post that online?” She laughed and answered, “Yes, I think I will.” What he said next stopped her. “Can you not?”[B] That’s when it dawned on her: She had been posting photos of him online without asking his permission. “We’re big advocates of bodily autonomy and not forcing him to hug or kiss people unless he wants to, but it never occurred to me that I should ask his permission to post photos of him online,” says Burbidge, a mom of two in Wakefield, Massachusetts. “Now when I post a photo of him online, I show him the photo and get his okay.”[C] When her 8-month-old is 3 or 4 years old, she plans to start asking him in an age-appropriate way, “Do you want other people to see this?” That’s precisely the approach that two researchers advocated before a room of pediatricians (儿科医生) last week at the American Academy of Pediatrics meeting, when they discussed the 21st century challenge of “sharenting,” a new term for parents’ online sharing about their children. “As advocates of children’s rights, we believe tha t children should have a voice about what information is shared about them if possible,” says Stacey Steinberg, a legal skills professor at the University of Florida Levin College of Law in Gainesville.[D] Whether it’s ensuring that your child isn’t bullied over something you post, that their identity isn’t digitally “kidnapped”, or that their photos don’t end up on a half dozen child pornography (色情) sites, as one Australian mom discovered, parents and pediatricians are increasingly aware of the importance of protecting children’s digital presence. Steinberg and Bahareh Keith, an assistant professor of pediatrics at the University of Florida College of Medicine, say most children will likely never experience problems related to what their parents share, but a tension still exists between parents’ rights to share their experiences and their children’s rights to privacy.[E] “We’re in no way trying to silence parents’ voices,” Steinberg says. “At the same time, we recognize that children might have an interest in entering adulthood free to create their own digital footprint.” They cited a study presented earliersays. “The children wanted autonomy about this issue and were worried about their parents sharing information about them.”[F] Although the American Academy of Pediatrics offers guidelines recommending that parents model appropriate social media use for their children, it does not explicitly discuss oversharing by parents. “I think this is a very legitimat e concern, and I appreciate their drawing our attention to it,” David Hill, a fat her of five, says. He sees a role for pediatricians to talk with parents about this, but believes the messaging must extend far beyond pediatricians’ offices. “I look forward to seeing researchers expand our understanding of the issue so we can translate i t into effective education and policy,” he says.[G] There’s been little research on the topic, Steinberg wrote in a law article about this issue. While states could pass laws related to sharing information about children online, Steinberg feels parents themselves are generally best suited to make these decisions for their families. “While we didn’t want to create any unnecessary panic, we did find some concerns that were troublesome, and we thought that parents or at least physicians should be aware of tho se potential risks,” Steinberg says. They include photos repurposed for inappropriate or illegal means, identity theft, embarrassment, bullying by peers or digital kidnapping.[H] But that’s the negative side, with risks that must be balanced against the b enefits of sharing. Steinberg pointed out that parental sharing on social media helps build communities, connect spread-out families, provide support and raise awareness around important social issues for which parents might be their children’s only voice.[I] A C.S. Mott survey found among the 56 percent of mothers and 34 percent of fathers who discussed parenting on social media, 72 percent of them said sharing made them feel less alone, and nearly as many said sharing helped them worry less and gave them advice from other parents. The most common topics they discussed included kids’ sleep, nutrition, discipline, behavior problems and day care and preschool.[J] “There’s this peer-to-peer nature of health care these days with a profound opportunity for parents to learn helpful tips, safety and prevention efforts, pro-vaccine messages and all kinds of other messages from other parents in their social communities,” says Wendy Sue Swanson, a pediatrician and executive director of digital health at Seattle Children’s Hospital, where she blogs about her own parenting journey to help other parents. “They’re getting nurtured by people they’ve already selected that they trust,” she says.[K] “How do we weigh the risks, how do we think about the benefits, and how do we alleviate the risks?” she says. “Those are the questions we need to ask ourselves, and everyone can have a different answer.”[L] Some parents find the best route for them is not to share at all. Bridget O’Hanlon and her husband, who live in Cleveland, decided before their daughter was born that they would not post her photos online. When a few family members did post pictures, O’Hanlon and her husband made their wishes clear. “It’s been hard not to share pictures of her because people always want to know how babies and toddlers (学走路的孩子) are doing and to see pictures, but we made the decision to have social media while she did not,” O’Hanlon said. Similarly, Alison Jamison of New York decided with her husband that their child had a right to their own online identity. They did use an invitation-only photo sharing platform so that friends and family, including those far away, could see the photos, but they stood firm, simply refusing to put their child’s photos on other social media platforms.[M] “For most families, it’s a journey. Sometimes it goes wrong, but most of the time it doesn’t,” says Swanson, who recommends starting to ask children permission to post narratives or photos around ages 6 to 8. “We’ll learn more and more what our tolerance is. We can ask our kids to help us learn as a society what’s okay and what’s not.”[N] Indeed, that learning process goes both ways. Bria Dunham, a mother in Somerville, Massachusetts, was so excited to watch a moment of brotherly bonding while her first-grader and baby took a bath together that she snapped a few photos. But when she considered posting them online, she took the perspective of her son: How would he feel if his classmates’ parents saw photos of him chest-up in the bathtub? “It made me think about how I’m teaching him to have ownership of his own body and how what is shared today endures into the future,” Dunham says. “So I kept the pictures to myself and accepted this as one more step in supporting his increasing autonomy.”36.

Parents who share their parenting experiences may find themselves intruding into their children’s privacy.Section CDirections: T here are 2 passages in this section. Each passage is followed by some question 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.Perhaps it is time for farmers to put their feet up now that robots are used to inspect crops, dig up weeds, and even have become shepherds, too. Commercial growing fields are astronomically huge and take thousands of man-hours to operate. One prime example is one of Australia’s most isolated cattle stations, Suplejack Downs in the Northern Territory, extending across 4,000 square kilometers, taking over 13 hours to reach by car from the nearest major town—Alice Springs.The extreme isolation of these massive farms leaves them often unattended, and monitored only once or twice a year, which means if the livestock falls ill or requires assistance, it can be a long time for farmers to discover.However, robots are coming to the rescue.Robots are currently under a two-year trial in Wales which will train “farmbots” to herd, monitor the health of livestock, and make sure there is enough pasture for them to graze on. The robots are equipped with many sensors to identify conditions of the environment, cattle and food, using thermal and vision sensors that detect changes in body temperature.“You’ve also got color, texture and shape sensors looking down at the ground to check pasture quality,” says Salah Sukkarieh of the University of Sydney, who will carry out trials on several farms in central New South Wales.During the trials, the robot algorithms (算法) and mechanics will be fine-tuned to make it better suited to ailing livestock and ensure it safely navigates around potential hazards including trees, mud, swamps, and hills.“We want to improve the quality of animal health and make it easier for farmers to maintain large landscapes where animals roam free,” says Sukkarieh.The robots are not limited to herding and monitoring livestock. They have been created to count individual fruit, inspect crops, and even pull weeds.Many robots are equipped with high-tech sensors and complex learning algorithms to avoid injuring humans as they work side by side. The robots also learn the most efficient and safest passages, and allow engineers and farmers to analyze and better optimize the attributes and tasks of the robot, as well as provide a live stream giving real-time feedback on exactly what is happening on the farms.Of course, some worry lies in replacing agricultural workers. However, it is farmers that are pushing for the advancements due to ever-increasing labor vacancies, making it difficult to maintain large-scale operations.The robots have provided major benefits to farmers in various ways, from hunting and pulling weeds to monitoring the condition of every single fruit. Future farms will likely experience a greater deal of autonomy as robots take up more and more farm work efficiently.46. What may farmers be able to do with robots appearing on the farming scene?A)Upgrade farm produceB) Enjoy more leisure hours.C) Modify the genes of crops.D) Cut down farming costs.47. What will “farmbots” be expected to do?A)Take up many of the farmers’ routines.B)Provide medical treatments for livestock.C)Lead the trend in farming the world over.D)Improve the quality of pastures for grazing.48. What can robots do when equipped with high-tech sensors and complex learning algorithms?A)Help farmers choose the most efficient and safest passages.B)Help farmers simplify their farming tasks and management.C)Allow farmers to learn instantly what is occurring on the farm.D)Allow farmers to give them real-time instructions on what to do.49. Why are farmers pressing for robotic farming?A)Farming costs are fast increasing.B)Robotics technology is maturing.C)Robotic farming is the trend.D)Labor short is worsening50. What does the author think future farms will be like?A)More and more automated.B)More and more productive.C)Larger and larger in scale.D)Better and better in condition.Passage TwoQuestions 51 to 55 are based on the following passageThe public must be able to understand the basics of science to make informed decisions. Perhaps the most dramatic example of the negative consequences of poor communication between scientists and the public is the issue of climate change, where a variety of factors, not the least of which is a breakdown in the transmission of fundamental climate data to the general public, has contributed to widespread mistrust and misunderstanding of scientists and their research.The issue of climate change also illustrates how the public acceptance and understanding of science (or the lack of it) can influence governmental decision-making with regard to regulation, science policy and research funding.However, the importance of effective communication with a general audience is not limited to hot issues like climate change. It is also critical for socially charged neuroscience issues such as the genetic basis for a particular behavior, the therapeutic potential of stem cell therapy for neurodegenerative diseases, or the use of animal models, areas where the public understanding of science can also influence policy and funding decisions. Furthermore, with continuing advances in individual genome (基因组) sequencing and the advent of personalized medicine, more non-scientists will need to be comfortable analyzing complex scientific information to make decisions that directly affect their quality of life.Science journalism is the main channel for the popularization of scientific information among the public. Much has been written about how the relationship between scientists and the media can shape the efficient transmission of scientific advances to the public. Good science journalists are specialists in making complex topics accessible to a general audience, while adhering to scientific accuracy.Unfortunately, pieces of science journalism can also oversimplify and generalize their subject material to the point that the basic information conveyed is obscured or at worst, obviously wrong. The impact of a basic discovery on human health can be exaggerated so that the public thinks a miraculous cure is a few months to years away when in reality the significance of the study is far more limited.Even though scientists play a part in transmitting information to journalists and ultimately the public, too often the blame for ineffective communication is placed on the side of the journalists. We believe that at least part of the problem lies in places other than the interaction between scientists and members of the media, and exists because for one thing we underestimate how difficult it is for scientists to communicate effectively with a diversity of audiences, and for another most scientists do not receive formal training in science communication.51. What does the example of climate change serve to show?A)The importance of climate data is increasingly recognized.B)Adequate government funding is vital to scientific research.C)Government regulation helps the public understand science.D)Common folks’ scientific knowledge can sway policy making.52. What should non-scientists do to ensure their quality of life?A)Seek personalized medical assistance from doctors.B)Acquire a basic understanding of medical science.C)Have their individual genome sequenced.D)Make informed use of animal models.53.Why is it important for scientists to build a good relationship with the media?A)It helps them to effectively popularize new scientific information.B)It enables the public to develop a positive attitude toward science.C)It helps them to establish a more positive public image.D)It enables them to apply their findings to public health.54.What does the author say is the problem with science journalism?A)It is keen on transmitting sensational information.B)It tends to oversimplify people’s health problems.C)It may give inaccurate or distorted information to the public.D)It may provide information open to different interpretations.55.What should scientists do to impart their latest findings to the public more effectively?A)Give training to science journalists.B)Stimulate public interest in science.C)Seek timely assistance from the media.D)Improve their communication skills.Part IV Translation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.
