Physicians Aren’t Immune to Suicide and Depression
Medicine is a tough profession. It’s both tremendously rewarding and terribly demanding. Physicians are at the front lines of humanity,along with nurses, therapists and more. But being at the front lines can be risky: In a study, nearly 50 percent of doctors reporting that they were burned out. _______21_______ physicians, who are on call 24/7, have it the worst, followed closely by physicians working in other demanding subspecialties.
Studies about phys ician burnout are important but they typically don’t reflect this group’s high risk for even more dire mental health outcomes. Past research has also shown that physicians have a higher risk for suicide compared with other professions, _______22_______ in the top ten of risky professions. And a recent Lancet study notes that _______23_______, one physician dies from suicide every day in the U.S.
Suicidal tendencies _______24_______ the whole community. Health care systems respond with wellness meetings and other interventions but trainees still report feeling uncared for. In fact, several trainees privately tell me that they have to report fewer hours than they actually work.
Research studies _______25_______similar concerns to those I’ve heard. They repo rt that workplace factors contribute to physician suicide “including a large workload, competitiveness of training programs, pressure of patient and service demands and the risk of _______26_______ injury if physicians are forced to work in ways that conflict with their ethics and values.”
This new analysis is a major _______27_______ for understanding and appropriately responding to the mental health crisis today. Instead of _______28_______ on the past, the alarm has now been sounded: Greater attention must be paid to physician well-being. We want physicians to be safe and well, but we also need to help patients by
_______29_______ good health practices. Fortunately, preventive measures are already underway. Soon, we will hopefully be able to better ________30________ part of what is missing in the current conversation about physician mental health.

Trackers on Ice
Just because a scientist puts a GPS tracking collar on a wild polar bear does not mean the animal will obligingly keep it on．_______31_______, these huge collars are purposefully loose．If one becomes annoying, a bear can
_______32_______ it．But scientists have now found a way to use _______33_______ from the discarded（丢弃的）devices．
"These dropped collars _______34_______ would have been considered garbage data," says Natasha Klappstein, a polar bear researcher at the University of Alberta．She and her colleagues instead used
_______35_______ from such collars, left on sea ice in Canada's Hudson Bay, to track the ice itself．For their study, published in June in The Cryosphere, the researchers identified twenty collars that transmitted movement data in line with ice drift rather than polar bear _______36_______ between 2005 and 2015．The resulting records of how melting ice typically drifts in Hudson Bay are unique．There are no easily _______37_______ on-the-ground sensors, and satellite observations often cannot accurately capture the motion of small ice sheets．
The team _______38_______ the discarded collars' movements with widely used ice-drift modeling data from the U.S．National Snow and Ice Data Center（NSIDC）．Collar data indicated that the NSIDC model underestimates the speed at which ice moves around in Hudson Bay-as well as the overall _______39_______ of drift．Over the course of several months, the model could drift away from an ice sheet's location by a few hundred kilometers, the researchers say．This means the bears may be working harder,when moving against the direction of the ice, than scientists had ________40________: "Since we're underestimating the speed of drift, we're likely underestimating the energetic effort of polar bears," says Natasha Klappstein．The research reveals ________41________ insight into how highly mobile ice moves．As melting increases in the coming years, such ice will likely become more ________42________ farther north, in the central Artic．Scientists had known NSIDC data could underestimate drift speeds, but "any time
we can find a data ________43________, it is a good thing．"
Plus, such data could improve predictions about how oil spills or other pollutants may ________44________ in seas．littered with drifting ice, says Walt Meier, a senior NSIDC research scientist, who was not involved in the study．The findings may even ________45________ future NSIDC models: "It's a really nice data set," Meier says．"And certainly one we'll take under consideration．"

Ⅳ．Reading Comprehension
Section B
Directions: Read the following three passages．Each passage is followed by several questions or unfinished statements．For each of them there are four choices marked A, B, C and D．Choose the one that fits best according to the information given in the passage you have read．
(A)
Each year, backed up by a growing anti-consumerist movement, people are using the holiday season to call
on us all to shop less.
Driven by concerns about resource exhaustion, over recent years environmentalists have increasingly turned their sights on our “consumer culture”. Groups such as The Story of Stuff and Buy Nothing New Day are growing as a movement that increasingly blames all our ills on our desire to shop.
We clearly have a growing resource problem. The produces we make, buy, and use are often linked to the destruction of our waterways, biodiversity, climate and the land on which millions of people live. But to blame these issues on Christmas shoppers is misguided, and puts us in the old trap of blaming individuals for what is a systematic problem.
While we complain about environmental destruction over Christmas, environmentalists often forget what the holiday season actually means for many people. For most, Christmas isn’t an add-on to an already heavy shopping year. In fact, it is likely the only time of year many have the opportunity to spend on friends and family, or even just to buy the necessities needed for modern life.
This is particularly, true for Boxing Day, often the target of the strongest derision(嘲弄) by anti-consumerists. While we may laugh at the queues in front of the shops, for many, those sales provide the one chance to buy items they’ve needed all year. As Leigh Phillips argues, “this is one of the few times of the year that peop le can even hope to afford such ‘luxuries’, the Christmas presents their kids are asking for, or just an appliance that works.”
Indeed, the richest 7% of people are responsible for 50% of greenhouse gas emissions. This becomes particularly harmful when you take into account that those shopping on Boxing Day are only a small part of our consumption “problem” anyway. Why are environmentalists attacking these individuals, while ignoring such people as Russian billionaire Roman Abramovich, who has his own￡1.5bn yacht with a missile defence system? Anyway,anti-consumerism has become a movement of wealthy people talking down to the working class about their life choices, while ignoring the real cause of our environmental problems. It is no wonder one is changing their behaviours—or that environmental destruction continues without any reduction in intensity.
46. It is indicated in the 1st paragraph that during the holiday season, many consumers .
A. ignore resource problems
B. are fascinated with presents
C. are encouraged to spend less
D. show great interest in the movement.
47. It can be inferred from Paragraphs 2 and 3 that the environmentalist movement .
A. has targeted the wrong persons
B. has achieved its intended purposes
C. has taken environment-friendly measures
D. has benefited both consumers and producers
48. The example of Roman Abramovich is used to show environmentalists’ .
A. madness about life choices
B. discontent with rich lifestyle
C. ignorance about the real cause
D. disrespect for holiday shoppers
49. It can be concluded from the text that telling people not to shop at Christmas is .
A. anything less than a responsibility
B. nothing more than a bias
C. indicative of environmental awareness
D. unacceptable to ordinary people
【答案】46. C 47. A 48. C 49. B

(C)
Dr. Donald Sadoway at MIT started his own battery company with the hope of changing the world's energy future．It's a dramatic endorsement（支持）for a technology most people think about only when their smartphone goes dark．But Sadoway isn't alone in boasting about energy storage as a missing link to a cleaner,more efficient, and more equitable energy future．
Scientists and engineers have long believed in the promise of batteries to change the world．Advanced batteries are moving out of specialized markets and creeping into the mainstream, signaling a tipping point for
forward-looking technologies such as electric cars and rooftop solar propels．
The ubiquitous（无所不在的）battery has already come a long way, of course．For better or worse, batteries make possible our mobile-first．lifestyles, our screen culture, our increasingly globalized world．Still, as impressive as all this is, it may be trivial compared with what comes next．Having already enabled a communications revolution, the battery is now poised to transform just about everything else．
The wireless age is expanding to include not just our phones, tablets, and laptops, but also our cars, homes, and even whole communities．In emerging economies, rural communities are bypassing the wires and wooden poles that spread power．Instead, some in Africa and Asia are seeing their first light bulbs illuminated by the power of sunlight stored in batteries．
Today, energy storage is a $33 billion global industry that generates nearly 100 gigawatt-hours of electricity per year．By the end of the decade, it's expected to be worth over 50 billion dollars and generate 160 gigawatt-hours, enough to attract the attention of major companies that might not otherwise be interested in a decidedly pedestrian technology．Even utility companies, which have long viewed batteries and alternative forms of energy as a threat, are learning to embrace the technologies as enabling rather than disrupting．
Today's battery breakthroughs come as the world looks to expand modern energy access to the billion or so people without it, while also cutting back on fuels that warm the planet．Those simultaneous challenges appear less overwhelming with increasingly better answers to a centuries-old question: how to make power portable．To be sure, the battery still has a long way to go before the nightly recharge completely replaces the weekly trip to the gas station．A battery-powered world comes with its own risks, too．What happens to the centralized electric grid, which took decades and billions of dollars to build, as more and more people become "prosumers," who produce and consume their own energy on site?
No one knows which——if any——battery technology will ultimately dominate, but one thing remains
clear．The future of energy is in how we store it．
53. What does Dr. Sadoway think of energy storage?
A. It involves the application of sophisticated technology．
B. It is the direction energy development should follow．
C. It will prove to be a profitable business．
D. It is a technology benefiting everyone．
54. What is most likely to happen when advanced batteries become widely used?
A. Mobile-first lifestyles will become popular．
B. The globalization process will speed up．
C. Communications will take more diverse forms．
D. The world will undergo revolutionary changes．
55. In some rural communities of emerging economies, people have begun to _______________．
A. find digital devices simply indispensable
B. communicate primarily by mobile phone
C. light their homes with stored solar energy
D. distribute power with wires and wooden poles
56. What does the author imply about the centralized electric grid?
A. It might become a thing of the past．
B. It might turn out to be a "prosumer"．
C. It will be easier to operate and maintain．
D. It will have to be completely transformed．
【答案】53. B 54. D 55. C 56. A
Section C
Directions: Read the following passage and fill in each blank with the sentence that best fits the
context．Each sentence can only be used once．Note that there are two sentences more than you need．
Twilight of the Brands
It's a truism of business-book thinking that a company's brand is its "most important asset," more valuable than technology or patents or manufacturing prowess．But brands have never been more fragile．The reason is simple: consumers are supremely well informed and far more likely to investigate the real value of products than to rely on logos．
Absolute Value, a new book by Itamar Simonson and Emanuel Rosen shows that, historically, the rise of brands was a response to an information-poor environment．_______57_______ If a car was made by G.M, or a ketchup by Heinz, you assumed that it was pretty good．It was hard to figure out if a new product from an unfamiliar company was reliable or not, so brand loyalty was a way of reducing risk．
Today, consumers can read much research about whatever they want to buy．This started back with Consumer Reports, which did objective studies of products．_______58_______ It has given ordinary consumers easy access to expert reviews, user reviews, and detailed product data, in an array of categories．
A recent study found that eighty per cent of consumers look at online reviews before making major purchases, and a host of studies have logged the strong influence those reviews have on the decisions people
make．_______59_______ An undesirable product can become a laughingstock（笑柄）in a matter of hours．In the old days, you might buy a Sony television set because you'd owned one before, or because you trusted the brand．Today, such considerations matter much less than reviews on Amazon and Engadget and CNET. As Simonson said, "each product how has to prove itself on its own．"
It's been argued that in a world where consumers are overwhelmed with information, the information will actually make brands more valuable．Indeed, the role a brand plays in people's lives has become all the more important, But information overload is largely a myth．_______60_______ And this has made customer loyalty pretty much a thing of the past．Only twenty-five per cent of American respondents in a recent study said that brand loyalty affected how they shopped．
A. But what really weakened the power of brands is the Internet．
B. For consumers this is ideal: heightened competition has raised quality and held down prices．
C. When consumers had to rely on advertisements and their past experience with a company, brands served as a
guarantee for quality．
D. A large quantity of consumers fail to get a great deal of information efficiently and effectively．
E. The rise of social media has sped up the trend to an astonishing degree．
F. Most consumers figure out how to find what they're looking for without spending huge amounts of time online．【答案】57. C 58. A 59. E 60. F

Can advertising support a free Internet?
The supporters of an open, democratic Internet, funded mainly by advertising, are facing some big questions about how their vision will unfold．A freely accessible digital world, _______61_______ websites and social networks are open to all, is the dream of many．But critics wonder if this is desirable or even possible．Brands _______62_______(shift) a huge proportion of their marketing budgets into online advertising in recent years．But while many campaigns hit the spot, others _______63_______ be annoying, intrusive and irrelevant．To discuss the future of online advertising, the Guardian teamed up with advertising technology provider AppNexus to run a roundtable discussion．The discussion was conducted under the Chatham House Rule, where comments were made on condition that they were not attributed to the speakers, _______64_______(encourage) a free-flowing discussion．
A key point of argument in the discussion was _______65_______ the Internet should be funded．One participant was passionate about the ad-funded model: "It is a wonderful tool for accessing information, for consuming information and for the distribution of brands．"But another thought that the quality of content on the Internet inevitably suffers "_______66_______ you have other resources to fund it．"There are fears that ad revenue is insufficient to pay for all the content that is needed for the web．"Generally speaking, the ad-funded model puts a downward pressure on the quality of content．"
The discussion returned to the question: will advertising continue as the main source of funding for the web,
_______67_______(fuel) its growth? Digital advertising faces some serious challenges if it is to keep the web free-one of which is concerns over the ethics of tracking people's online behavior _______68_______ their permission．The success of online ad campaigns is determined by the data that brands can access about Internet users．How old are they? What are their interests? Are they male or female, single or with children? Much of this data will be collected from cookies _______69_______(download) on to users' computers．Cookie data allows web publishers to track users' online journeys and observe the actions they take on different websites．They can then sift through（筛选）data to identify ________70________（appropriate）places to run the ads．
