2 . Female penguins get stranded

Every year, thousands of Magellanic penguins (麦哲伦企鹅) get stranded along the coast of South America, but, _________ about 75% of those that get stuck are female. Now scientists say they have worked out what is behind the gender _________: the females migrate further north than males.

Magellanic penguins finish breeding in Patagonia in February, and, during the _________ winter months, head north, reaching as far as Brazil, in search of anchovies (风尾鱼). But every year thousands become stranded, with many _________ to safety on board military aircraft by human.

Writing in the journal Current Biology, researchers in Japan and Argentina report how they _________ tracking device to eight male and six female penguins in 2017 and tracked where the birds went after they left the breeding grounds of Cabo dos Bahfa in Argentina and began the migration north in April.

Previously it was unknown whether male and female’s took different paths or not. “Although some _________ are made, the exact reason for the _________ stranding has been unknown due to the lack of information on their behavior outside the breeding season.” said Takashi Yamamoto, a co-author of the report from the Institute of Statistical Mathematics in Japan.

The results from the study offer a clearer picture. _________ the authors note that only a small number of penguins were tracked, all the female’s generally traveled further north. The male, meanwhile, predominantly stuck to waters of the Argentinian coast. The study also found male _________ dived deeper than female’s: about 59 metres compared with about 35 metres.

The authors offer a number of reasons why males and females may head to different areas— including to avoid __________ for food—and why they dive to different __________ —the females’ smaller bodies may restrict the depths they can reach. They also suggest the different sexes may seek waters of different temperatures, with the __________ females preferring warmer, shallower surroundings.

While researchers are still trying to understand why penguins end up stranded, Yamamoto and colleague’s suggest those that end up further north may have used more energy swimming or catching __________ prey, leaving them exhausted. Climate change, pollution in the area or injury from fishing equipment could also play a role. Reports of standings have noted that many penguins are unwell or exhausted, with some even washing up dead.

“__________, plastic remains have been reported in the stomach of beach-washed Magellanic penguins,” said Yamamoto, adding that a stewed sex ratio could potentially lead to a population decline.

While the findings may not help prevent strandings, Yamamoto said it could help with __________ of the species. “If we do not consider any action, such as marine zoning, I expect that the number of stranding individuals will increase.”

3 . There are often many assumptions made about young people aged 15 to 21, but only a few can be proved with hard evidence. Now, new research has been published to help people get a better idea of these _________ young people.

According to an international survey in 2016, young people in emerging (新兴的) economies like China and India have a _________sense of hope about the future, compared with those living in Europe, North America and Australia.

The survey was _________ between September and October by the Varkey Foundation, a UK-based non-profit organization. It surveyed 20,000 young people who were born between 1995 to 2001 in 20 countries. They were asked questions about their hopes, ambitions, personal views and community values.

It was found that 53 percent of those questioned in China thought the world was becoming a better place – the highest percentage among the countries surveyed. Some 93 percent of them also felt _________ for the future because of advances in technology, such as in medicine, renewable energy and computing.

Indian youth were the second most_________, with 49 percent taking a positive view of the world’s prospects.

_________, young people in France, Italy and Turkey had the most negative outlook on the future, with fears about extremism and the rise of global terrorism.

“At a time of nationalist and populist (民粹主义的) movements (such as Brexit (脱欧) or US President Donald Trump’s plans to build a wall along the US border) that focus on the _________between people, the evidence shows that young people share a _________ similar view of the world,” Vikas Pota, chief executive of the Varkey Foundation, told The Guardian.

“They are a generation that is deeply _________ about the future of the world,” he added.

As for young people in China, what they __________ most is the impact of climate change — some 82 percent of those who responded to the__________ said so.

Pota said it was __________ that young people in China were aware how serious the problem of climate change is.

“This is surely a hopeful development. The young population of China is more aware than anyone of the seriousness of the climate crisis – and will be__________ for change,” he told South China Morning Post.

The overall survey showed a sense of optimism in the __________ and opinions of the generation that is likely to shape the next few decades, according to Pota.

“They are more likely to travel, to migrate across borders and to forge (建立) friendships in other countries than any __________ generation,” he said. “Global citizenship is not dead. It could just be getting started.”

4 . It was a long way up the humble zipper (拉链) to become the mechanical wonder that has kept our lives “together” in many ways. The zipper had passed through the hands of several gifted inventors, though none _________ the general public to accept the zipper as part of everyday life. It was the magazine and fashion industry that made zipper the popular item it is today.

The story began when Elias Howe, inventor of the sewing machine, received a patent (专利) in 1851 for an “Automatic, Continuous Clothing Closure.” However, it didn’t go much further beyond that simple _________ description.

Perhaps it was the success of the sewing machine, that stopped Elias from _________ marketing his clothing closure system. As a result, Howe missed his chance to become the _________ “Father of the Zip.”

Forty-four years later, inventor Whitcomb Judson marketed a “Clasp Locker” device _________ to the system described in the 1851 Howe patent. Being first to market, Whitcomb got _________ for being the “inventor of the zipper.” The clasp locker was released at the 1893 Chicago world’s Fair by his universal fastener (扣件) company and was met with little _________ success. Not many products were sold at that time.

It was an electrical engineer named Gideon Sundback who helped make the zipper the hit it is today.

_________ hired to work for the Universal Fastener Company as an ordinary employee, Sundback relied on his excellent design skills to rise to the position as head designer. When Sunback’s wife died in 1911, the sad husband busied himself at the design table focusing on the _________ of the fastener. In December of 1913, he came up with what would become the __________ zipper. __________, it still took 20 more years to persuade the fashion industry to seriously promote the new closure on clothing.

In the 1930s, a sales campaign began for children’s clothing featuring zippers. The campaign advertised zippers as a way to promote __________ in young children as the devices made it possible for them lo dress by themselves. And Esquire magazine declared the zipper the “Newest Tailoring Idea for Men.” saying it would __________ “the possibility of unintentional and embarrassing dressing moments.”

Today the zipper is everywhere and is used in clothing, luggage, leather goods and __________ other objects. Thousands of zipper miles are produced daily to meet the needs of consumers, __________ the early efforts of the many famous zipper inventors and developers.

5 . One of the roles of the Nobel Prize for literature is to shine a light on someone who has been less visible than they deserve. That role was _______ this year in the announcement of Abdulrazak Gurnah as winner.

Unlike previous popular recipients living in Britain, he is not a _______. He could, as he said after the announcement, have reached more readers, but his publications _______ to grant him that. His publisher felt sorry for the fact that he “is one of the greatest living African writers; yet no one has ever _______ him,” but with this he did not agree: “I didn’t think I was ignored.”

There is a(n) _______ , here, that has to do with who is doing the looking, and what counts as officially being noticed. There is also a point of _______: calling Gurnah an African writer. In fact, while that seems to broaden horizons, it narrows and distances what he is doing. Gurnah was born in Zanzibar, and left for Britain when he was 18, _______ regional conflicts for what he hoped would be calmer waters, which turned out to be stronger dark current. He has lived in Britain ever since.

He began and stuck to writing to _______, to himself, of the shock -- of racism, rejection, poverty and loneliness. His ten novels return to it _______, which begins in 1996’s Admiring Silence. His work exists because of Britain as well as Zanzibar; it may ________ both or wholly neither. It arrives out of a(n) ________ of English literature (Gurnah is professor of literature at the University of Kent), and his first language, the rhythms and stories of Islam.

________, many of the UK's thirteen Nobel-winning writers were born elsewhere as by 2019, 14% of the UK’s population were born abroad. People might also be astonished at how many of those countries were once part of the British empire. Gurnah has spoken of how much of the world is still processing the wounds that colonialism ________, especially the experience of “losing your place in the world”-- where place is not just ________, but also belonging, status and culture.

In this sense, Gurnah’s work, which ________ those who might not have been remembered in history--shopkeeper, homemakers, students and refugees, could not be more British. But, more importantly, it could not be more universal.

7 . Switzerland is surrounded by three of Europe’s major—and most populous—countries: France, Germany and Italy.

Today, Switzerland is an indispensable part of the European transport network and ________ a superb motorway and railway infrastructure. Five international airports in Zurich, Geneva. Basel. Bern and Lugano offer direct ________ to destinations around the world.

Switzerland is a popular place to do business, a center of education and a favorite travel destination. At the heart of this success story lies a stable political system. The county has not gone through any major political changes since the foundation of the federal state inn 1848. This has created space for economic, social and artistic development. Federalism, the successful integration of different cultures, and the mechanisms of direct democracy are all means to increase the ________ of its citizens and residents. This process of forming unity out of ________ has often been seen as exemplary. And, of course, the country is small and ________, which also contributes to the high quality of life in Switzerland.

Political stability is also ________ in an economic system that manages to balance a free market economy with social responsibility.________ are very rare in Switzerland.________ its deeply rooted work ethic and high educational standards, this social harmony represents one of Switzerland’s key advantages as a place to do business and has made a major contribution to its economic development.

Stability, a well-developed sense of service and discretion, and a strong currency have turned Switzerland into a leading financial center. From a historical ________, the fact that the county was not involved in the two world wars has contributed to this development. It is a country with ________ natural resources, so the strength of its import industry has also played a significant part. Not being a member of the EU. Switzerland is also not part of the so-called Eurozone. For this reason, the use of the euro in everyday life is limited to Switzerland’s border and tourist regions.

In terms of income, assets and per capita gross national product. Switzerland ranks among the top in the world.

The ________ excellent standard of living is also based on the high level of education and corresponding work ethic.________, people work 42 hours per week. Taxes are comparatively low, both for business and for businesses and for individuals. Corporate taxation as well as the rate of value added tax are among the lowest that can be found anywhere in the world.

All these factors make Switzerland a safe country with a low crime rate. The Swiss ________ being tidy and clean, which is why recycling is popular .________ to this a rich cultural variety and beautiful scenery, and you get a quality of life that is hard to beat.

8 . Last week, I taught a case study on the decline of Nokia to my MBA students. I asked them, “Why did Nokia fall from industry _________ to also-ran position in the space of less than five years?” Their answers were _________:

“They lost touch with their customers.” True, but almost tautological-and interesting to note that this is the same Nokia that in the early 2000s was praised for its _________-centric marketing and design capabilities.

“They _________ to develop the necessary technologies.” Not really true-Nokia had a prototype touch screen before the iPhone was launched, and its smartphones were _________ superior to anything Apple, Samsung, or Google had to offer during the late 1990s.

“They didn’t recognize that the basis of competition was shifting from the hardware to the ecosystem.” _________, not really true-the “ecosystem” battle began in the early 2000s, with Nokia joining forces with Ericsson, Motorola, and Psion to create Symbian as a _________ technology that would keep Microsoft at bay.

Through this period, the people at Nokia were _________ the changes going on around them, and they were never short of leading-edge technology or clever marketers. Where they struggled was in transmitting _________into action. The company lacked the capability to change in a decisive and committed way.

The failure of big companies to __________ to changing circumstances is one of the principal puzzles in the world of business. Occasionally, a genuinely “disruptive” technology, such as digital imaging, comes along and __________ an entire industry. But usually the sources of failure are more dull and avoidable—a failure to __________ technologies that have already been developed, an arrogant disregard(傲慢的漠视) for changing customer demands, a self-satisfied attitude towards new competitors.

In such cases, the final responsibility for __________ rests with the CEO. But if such failures are to be avoided, it is clear that the CEO cannot do it on his or her own. People across the firm must keep their eyes open to __________ in their business, and to take responsibility to push their new ideas and __________ existing ways of working. Obviously, this isn't easy to do, but if there is a better understanding of the problem then there is a chance for improvement.

9 . Most of us have no difficulty recognizing luck when it’s on apparent display, as when someone wins the lottery. But _________ often plays out in delicate ways and it’s easy to construct narratives that portray success as out of everything but luck. These misleading stories have surprising implications for human mindset, downplaying the power of chances.

Consider the history of the Mona Lisa. After having staved in the _________ for most of its early existence, the painting was pushed into the spotlight in 1911 when it was stolen from Louvre. The famous theft remained _________ for two years until a maintenance worker was arrested after trying to sell the painting. His arrest caused a second wave of _________, with the painting on everyone’s lips. As in the art world, it is so too in the world of work. Almost every career path consists of a sequence of steps, each of which depends on former ones. Inevitably, some of those _________ steps can be influenced by chance factors, which, as a result, are sure to affect the following process. So it is reasonable to conclude that _________ all successful careers involve at least a certain degree of luck.

One’s date of birth _________, for example. According to a study, most children born in the summer tend to be among the youngest members of their class, which explains why they are less likely to hold _________ positions during high school and thus, less likely to land good jobs later in life.

To acknowledge the power of chance events is not to suggest that success is independent of _________. Charlie Munger has said. “The safest way to get what you want is to __________ what you want.”

Of course, luck counts too. Being born in a good education system is a kind of luck we can control— that is, at least we can decide how lucky our children will be. But in America, we’ve been doing a bad job as the budget for education has __________. The human tendency to __________ luck’s role has caused this troubling state by unwillingness to invest in education, the strong system of which can produce __________ for the next generation.

Luckily, there is a solution. Guiding people to __________ their good fortune tends to make them more willing to contribute to the __________, according to a study. So try to engage your successful friends in reviews about their experiences with luck. In the process, the next generation’s odds of success may well increase and meanwhile, all the social members are more likely to enjoy the improved public service.

10 . It is a tradition of corporate architecture. A company’s top executives get offices on the top floor with the biggest windows and best views. However, nowadays some bosses choose to “hot-desk”（轮用办公桌） with everyone else.

One argument for such a(n) ________ can be made. Staff morale （士气）would ________ if the employees are stuffed in open-plan offices while the executives occupy the spacious offices. When the executives sit alongside their teams, they will be more in touch with how projects are going and how staff are feeling. In theory, if the executives are ________, employees are more likely to approach them with problems.

But the bosses present all the time may ________ hurt morale. One of the joys of office life is the freedom to enjoy a bit of joking with colleagues. This may include the odd joke about the ________. In the presence of their boss, staff will be ________ in what they talk about and the tone of their comments. They may feel the need to sound serious at all times, for fear that the quality of their commitment to their work come into doubt. ________, the manager may be right behind them.

You also have to wonder whether executives will really spend every morning searching for a place to sit. Some hot desks will be a lot hotter than others. Once the chief financial officer has picked a desk on day one, the junior staff will ________ that particular spot on subsequent days. In contrast, anyone who works closely with a particular executive will be ________ to pick a desk close by.

The lingering（逗留不走的）boss presents other ________. Anyone who has worked in an open-plan office will acknowledge that other colleagues’ talking can make it hard to ________ at times. Managers may find themselves constantly being approached by team members with questions or problems for them to solve. Many people resort to headphones to shut out the background noise and to ________ their unavailability. But if managers do that, they run the risk of seeming shut off from their colleagues.

One study found that at firms that ________ to open-plan design, face-to-face interactions fell by 70%. Like an animal caught on open ground without cover, many people do not like being constantly observed. In the ________ of a physical barrier, they create a fourth wall, ________ their desire for privacy by facial expressions or brief replies to questions.
