1 . Recently I attended several meetings where we talked about ways to attract students and keep younger faculty members from going elsewhere. It seems higher education has become an industry of meeting-holders whose task is to “solve” problems — real or imagined. And in my position as a professor at three different colleges, the actual problems in educating our young people and older students have deepened, while the number of people hired — not to teach but to hold meetings — has increased significantly. Every new problem creates a new job for an administrative fixer. Take our Center for Teaching Excellence. Contrary to its title, the center is a clearing house (信息交流中心) for using technology in classrooms and in online courses. It's an administrative sham (欺诈) of the kind that has multiplied over the last 30 years.
I offer a simple proposal in response: Many of our problems — class attendance, educational success, student happiness and well-being — might be improved by cutting down the bureaucratic (官僚的) mechanisms and meetings and hiring an army of good teachers instead.
If we replaced half of our administrative staff with classroom teachers, we might actually get a majority of our classes back to 20 or fewer students per teacher. This would be an environment in which teachers and students actually knew each other. The teachers must be free to teach in their own way — the curriculum should be flexible enough so that they can use their individual talents to achieve the goals of the course.
Additionally, they should be allowed to teach, and be rewarded for doing it well. Teachers are not people who are great at and consumed by research and happen to appear in a classroom. Good teaching and research are not exclusive, but they are also not automatic companions. Teaching is an art and a craft, talent and practice; it is not something that just anyone can be good at. It is utterly confusing to me that people do not recognize this, despite the fact that pretty much anyone who has been a student can tell the difference between their best and worst teachers.

2 . Patients often come into my office and ask, “How can I look younger?” While I always suggest healthy living — a balanced diet and regular exercise — in order to look and feel younger, I have never thought of facial exercises as part of that plan. That is, until a recent study, published in JAMA Dermatology (皮肤学), showed promising results that routine facial exercise may slow the merciless tide of time.
The theory behind the study originates from the fact that a major part of facial aging is due to the loss of fat and soft tissue, which leads to the growth and spread of wrinkles. If we can lift weights at the gym and enlarge muscles in arms, why couldn’t the same be done for muscles in our faces, therefore to create a more youthful face?
The concept of facial exercise is not a new one. A simple Internet search will produce a lot of blog posts and books on the subject, as well as various programmes that promise to be the next fountain of youth. What the JAMA Dermatology researchers did in their study, which was the first of its kind, was to examine this question from a more strict scientific aspect. They enrolled 27 women between the ages of 40 and 65 to perform daily, 30-minute exercises for eight weeks, and then continue every other day for a total of 20 weeks.
Dermatologists who did not know the participants were asked to rate their photographs before and after the exercise. The dermatologists found an improvement in cheek fullness and estimated the age of the participants at 51 years of age at the start of the programme and 48 at the end of the 20-week study. Furthermore, all the participants felt improvement in their own facial appearance at the end of the study.
While these results seem exalting, the study has some obvious limitations. Of the 27 patients involved, 11 gave up before completing the study. One reason may be that the programme was to time-consuming, clocking in at 30 minutes a day. The overall small size of the study also limits its generalizability to the larger population. In addition, there was also no control group, which would have helped reduce the possibility that this improvement happened by chance.
It’s also hard to draw conclusions about the longevity of these results. Probably the exercises must be continued to keep their effects. But for how long? And how frequently? Which exercises are most effective? Most studies are need to answer these questions.

3 . International governments’ inaction concerning sustainable development is clearly worrying but the proctive（主动出击的）approaches of some leading-edge companies are encouraging. Toyota, Wal-Mart, DuPont, M&S and General Electric have made tackling environmental wastes a key economic driver.
DuPont committed itself to a 65% reduction in greenhouse gas emissions in the 10 years prior to 2010. By 2007, DuPont was saving $2.2 billion a year through energy efficiency, the same as its total declared profits that year. General Electric aims to reduce the energy intensity of its operations by 50% by 2015. They have invested heavily in projects designed to change the way of using and conserving energy.
Companies like Toyota and Wal-Mart are not committing to environmental goals out of the goodness of their hearts. The reason for their actions is a simple yet powerful realization that the environmental and economic footprints fit well together. When M&S launched its “Plan A” sustainability programme in 2007, it was believed that it would cost over £200 million in the first five years. However, the initiative had generated £105 million by 2011/12.
When we prevent physical waste, increase energy efficiency or improve resource productivity, we save money, improve profitability and enhance competitiveness. In fact, there are often huge “quick win” opportunities, thanks to years of neglect.
However, there is a considerable gap between leading-edge companies and the rest of the pack. There are far too many companies still delaying creating a lean and green business system, arguing that it will cost money or require sizable capital investments. They remain stuck in the “environment is cost” mentality. Being environmentally friendly does not have to cost money. In fact, going beyond compliance saves cost at the same time that it generates cash, provided that management adopts the new lean and green model.
Lean means doing more with less. Nonetheless, in most companies, economic and environmental continuous improvement is viewed as being in conflict with each other. This is one of the biggest opportunities missed across most industries. The size of the opportunity is enormous. The 3% Report recently published by World Wildlife Fund and CDP shows that the economic prize for curbing carbon emissions in the US economy is $780 billion between now and 2020. It suggests that one of the biggest levers for delivering this opportunity is “increased efficiency through management and behavioural change”-in other words, lean and green management.
Some 50 studies show that companies that commit to such aspirational goals as zero waste, zero harmful emissions, and zero use of non-renewable resources are financially outperforming their competitors. Conversely, it was found that climate disruption is already costing $1.2 trillion annually, cutting global GDP by 1.6%. Unaddressed, this will double by 2030.

4 . At the age of twelve years, the human body is at its most vigorous. It has yet to reach its full size and strength, and its owner his or her full intelligence; but at this age the likelihood of death is least. Earlier, we were infants and young children, and consequently more vulnerable (易受伤害的), later, we shall undergo a progressive loss of our vigor and resistance which, though unnoticeable at first, will finally become so steep that we can live no longer, however well we look after ourselves, and however well society, and our doctors, look after us.
This decline in vigor with the passing of time is called ageing. It is one of the most unpleasant discoveries which we all make that we must decline in this way, that if we escape wars, accidents and disease we shall eventually “die of old age”, and that this happens at a rate which differs little from person to person, so that there are heavy odds in favor of our dying between the ages of sixty-five and eighty. Some of us will die sooner, a few will live longer—on into a ninth or tenth decade. But the chances are against it, and there is a virtual limit on how long we can hope to remain alive, however lucky and robust we are.
Normal people tend to forget this process unless and until they are reminded of it. We are so familiar with the fact that ma ages, that people have for years assumed that the process of losing vigor with time, of becoming more likely to die the older we get, was something self-evident, like the cooling of a hot kettle or the wearing-out of a pair of shoes. They have also assumed that all animals, and probably other organisms such as trees, or even the universe itself, must in the nature of things “wear out”.
Most animals we commonly observe do in fact age as we do, if given the chance to live long enough; and mechanical systems like a wound watch, or the sun, do in fact run out of energy in accordance with the second law of thermodynamics (whether the whole universe does so is a moot point at present). But these are not analogous (类似的)to what happens when man ages. A run-down watch is still a watch and can be rewound. An old watch, by contrast, becomes so worn and unreliable that it eventually is not worth mending. But a watch could never repair itself —it does not consist of living parts, only of metal, which wears away by friction. We could, at one time, repair ourselves—well enough, at least, to overcome all but the most instantly fatal illnesses and accidents. Between twelve and eighty years we gradually lose this power, an illness which at twelve would knock us over, at eighty can knock us out, and into our grave. If we could stay as vigorous as we are at twelve, it would take about 700 years for half of us to die, and another 700 for the survivors to be reduced by half again.

5 . Up-skilling is the future - but it must work for everyone
Automation and job replacement will be one of the most significant challenges for the global economy of the coming decades. A 2017 Mckinsey report established that 375 million workers will need to switch occupational categories by 2030. The World Economic Forum suggests that by 2022, automation will replace 75 million jobs globally - but create 133 million new ones.
Research into the likelihood that a job will be impacted by digitization has largely focused on the "auto-matability" of the role and the following economic regional and political effects of this. What this research doesn't take into account is something more important for the millions of taxi drivers and retail workers across the globe: their likelihood of being able to change to another job that isn't automatable. Recent research suggests that the answer to this may be that the skills that enable workers to move up the ladder to more complex roles within their current areas might be less important than broader skills that will enable workers to change across divisions.
In July, Amazon announced that it would spend $700 million retraining around 30% of its 300,000 US workforce. While praiseworthy, it will be interesting to see the outcome. In the UK, the National Retraining Scheme has largely been led by employers, meaning that those on zero-hours contracts and part-time workers - often low-skilled --- will miss out. Governance will be a crucial element of ensuring that such schemes focus on individuals and life-long learning, rather than upskilling workers into roles that will soon also face automation.
According to the Mckinsey report, "growing awareness of the scale of the task ahead has yet to translate into action. Public spending on labour-force training and support has fallen for years in most member countries of the Organization for Economic Co-Operation and Development," which impacts more than just the low-skilled.
The global impact of automation is also put into relief by research demonstrating that, between 1988 and 2015, income inequality increased throughout the world. Billions of people do not have the essentials of life as defined by the UN Sustainable Development goals.
Alongside climate change, automation is arguably tech's biggest challenge. As with globalization, governments and employers -- and us workers -- ignore its potential consequences at risk to ourselves.
1. It can be known from Paragraph 2 that ________.| A．recent research has found ways to face automation |
| B．broad skills are of great significance in changing jobs |
| C．regional economy can affect the automatability of a job |
| D．it is even harder for workers to move up the social ladder |
| A．Supportive. | B．Critical | C．Doubtful | D．Sympathetic |
| A．Less spending on training | B．A slowdown of globalization |
| C．Social unrest and instability. | D．An increase in income inequality |
| A．argue the urgency of creating new jobs |
| B．compare globalization with automation |
| C．analyze the automatability of certain jobs |
| D．stress the important of upskilling workers |
6 . Culture can affect not just language and customs, but also how people experience the world on surprisingly basic levels.
Researchers, with the help of brain scans, have uncovered shocking differences in perception(感知) between Westerners and Asians, what they see when they look at a city street, for example, or even how they perceive a simple line in a square, according to findings published in a leading science journal
In western countries, culture makes people think of themselves as highly independent entities(实体) .When looking at scenes, Westerners tend to focus more on central objects than on their surroundings. East Asian cultures, however emphasize inter-dependence. When Easterners look at a scene, they tend to focus on surroundings as well as the object.
Using an experiment involving two tasks, Dr Hedden asked subjects to look at a line simply to estimate its length, a task that is played to American strengths. In another, they estimated the line's length relative to the size of a square, an easier task for the Asians.
The level of brain activity, by tracking blood flow, was then measured by Brain Scanners. The experiment found that although there was no difference in performance, and the tasks were very easy, the levels of activity in the subjects’ brains were different. For the Americans, areas linked to attention lit up more, when they worked on the task they tended to find more difficult--estimating the line's size relative to the square. For the Asians, the attention areas lit up more during the harder task also--estimating the line's length without comparing it to the square. The findings are a reflection of more than ten years of previous experimental research into east-west differences
In one study, for instance, researchers offered people a choice among five pens, four red and one green. Easterners were more likely to choose a red pen while Westerners were more likely to choose the green one.
Culture is not affecting how you see the world, but how you choose to understand and internalize(使内化) it. But such habits can be changed. Some psychological studies suggest that when an Easterner goes to the West or vice versa, habits of thought and perception also begin to change. Such research gives us clues on how our brain works and is hopeful for us to develop programs to improve our memory, memory techniques and enhance and accelerate our learning skills.

7 . Are we getting more stupid? According to Gerald Crabtree, a scientist at Stanford University in the US, we are.
You may not want to hear this, but Crabtree believes that human intelligence reached its peak more than 2,000 years ago and ever since then has been going downhill. “If an average Greek from 1,000 BC were transported to modern times, he or she would be one of the brightest among us,” Crabtree told The Guardian.
At the heart of Crabtree’s thinking is a simple idea. In the past, intelligence was critical for survival when our ancestors had to avoid dangerous animals and hunt for food. The difference of being smart or stupid is often life or death. However, after the spread of agriculture when our ancestors began to live in dense farming communities, the need to keep their intelligence in peak-condition gradually reduced.
This is not hard to understand. Most of the time, pressure is what keeps us going—you need the pressure from your teachers to finish your homework the pressure of looking pretty encourages you to lose weight when summer comes. And the same is also true of our intelligence-if we think less, we become less smart.
These mutations (变异) are harmful to our intelligence and they were all developed in the past 3,000 years. The other evidence that Crabtree holds is in our genes. He found that among the 2,000 to 5,000 genes that we have that determine human intelligence, there are two or more mutations in each of us.
However, Crabtree’s theory has been criticized by some who say that early humans may have better hunting and surviving abilities, but people today have developed more diverse intelligence. For example, spearing (用矛刺) a tiger doesn’t necessarily require more brainpower than playing chess or writing a poem. Moreover, the power of modern education means lot more people have the opportunity to learn nowadays.
“You wouldn’t get Stephen Hawking 2,000 years ago. He just wouldn’t exist,” Thomas Hills of the University of Warwick, UK, told Live Science. “But now we have people of his intellectual capacity doing things and making insights (洞察力) that we would never have achieved in our environment of evolutionary adaptation (进化适应).”
1. What is Crabtree’s recent finding according to the article?| A．The Greeks from 1,000 BC could have been the smartest in human history. |
| B．Our ancient ancestors had no better surviving abilities than we do nowadays. |
| C．Mutations in genes that decide human intelligence have affected the development of intelligence. |
| D．Humans have been getting steadily more intelligent since the invention of farming. |
| A．had much more genes that determine human Intelligence |
| B．were forced to be smart due to natural selection pressures |
| C．relied more on group intelligence than individual intelligence |
| D．developed a diverse intelligence to adapt to the hard realities |
| A．people today are under much more pressure than early humans |
| B．it’s unreasonable to compare hunter’s and a poet’s intelligence |
| C．modern education is far more advanced than ancient education |
| D．human intelligence nowadays is different from that of the distant past |
| A．He is for Crabtree’s theory. |
| B．He is against Crabtree’s theory. |
| C．He is worried about Crabtree’s theory. |
| D．He is confused about Crabtree’s theory. |
Now rewind this picture 1,839 years. You are in the same seat, only you are watching classical Greek entertainment.
The city of Athens is a fun mix of the old and the new, the classic and the modern. Often a little shop is located next to the ruins of a temple, which is only a block from a large, air-conditioned hotel. The great city of 2,500 years ago is still visible today.
Ruins are the most obvious sign of ancient Athens, and the most famous of these is the Acropolis(卫城). The Acropolis is a large hill that was the center of life in Athens. On its slopes were temples, monuments, and theaters. From the top, you can see how the urban area of Athens stretches out in every direction.
On the top of the Acropolis is the Parthenon. This was once a huge temple to Athena, the city’s patron. It was first completed in 432 B.C., but has been damaged and destroyed several times. However, visitors can still see the “tricks” used in building the Parthenon. The columns along the outside lean inward, and are slightly fatter in the middle. The temple is also higher in the middle than on the sides. All these effects make the Parthenon look perfectly straight from a distance.
Only a block away from the Acropolis is the neighborhood of Plaka. The area, with its little shops and restaurants, is very popular with both tourists and locals, and is an important part of modern Athenian culture. Many great thinkers, writers, and political leaders lived in ancient Athens. The ruins of their homes and favorite spots are scattered throughout the busy port city. The hill where St. Paul addressed early Christian Athenians is located near the Acropolis. Great thinkers such as Perikles and Demosthenes spoke to the civil assemblies held at the Pnyx Hill. Today the Pnyx is an open-air theater for light and sound shows.
Tourism is very important to people who live in modern-day Athens. Thousands of people come every year to see these ruins and to tour the many museums that house artifacts from ancient times. This provides many jobs and brings money into Athens, which helps the city pay for improvements. Athenians take pride in the accomplishments of their ancestors, and people from all around the world come to admire them. By looking around the city today, we can imagine what life was like in ancient Athens.
1. Which of the following statements is INCORRECT about the city of Athens?| A．The culture of the city is a mixture of the old and modern. |

9 . MEGHAN YOUNG is a professional Instagram star. She gets paid to climb beautiful mountains, photograph their glittering (闪闪发光的) summits and post about her adventures to her fans.
Young graduated from Seattle University’s school of Law in 2015. But she decided she didn’t want to become a lawyer. Her parents were shocked by the decision. “They were worried about what I was going to do,” Young says. “How was I going to find career stability?”
But her legal skills haven’t gone to waste. Once companies express an interest in working with her, there’s the tough task of negotiating the terms (条款) of the deal. And the work is still unfinished even after she’s done take the photos. When Young returns from her adventures, she carefully edits the images and writes captions to go along with them. Once the posts are public, businesses sometimes don’t pay on time. That's when she needs to follow up. Her least favorite problem is when she discovers that a company has used her photos in a way that violates the terms of the contract.That usually leads to time-consuming email exchanges.
Social media influencing is not as effortless as it seems. The stress it creates even has its own name: creator burnout (精疲力竭) . Young used to obsessively check her post’s performance, which she says will “drive you crazy”, so she stopped. But if she doesn’t reply, people will stop commenting.Without that engagement on her posts, brands won’t want to keep paying her. Therefore, she had to accept the fact that she’ll be tethered (拴住) to her phone as long as she’s in this line of work.
Beyond the day-to- day headaches of a career online, social media’s inherent (固有的) uncertainly also poses problems for creators. There are times when Young is staring at the calendar without another project in the works. In the long term, it can be risky to focus a career on a single platform, or even on social media itself.
Yet Young says it’s all been worth it, because the sponsorship allow her to spend much of her life in the mountains. Her ideal day starts with unzipping her tent at dawn so she can take pictures of the sunrise reflecting on snowy summits around her. Few jobs in the world would allow her to do that so consistently (一贯地) .

10 . The Ebro Delta, in Spain, famous as a battleground during the Spanish Civil War, is now the setting for a different contest, one that is making rice farmers fight against two enemies: the rice-eating giant apple snail, and rising sea levels. What happens here will have a bearing on the future of European rice production and the overall health of southern European wetlands.
Located on the Mediterranean, just two hours south of Barcelona, the Ebro Delta produces 120 million kilograms of rice a year, making it one of the continent’s most important rice-growing areas. As the sea creeps into these fresh-water marshes, however, rising salinity (盐度) is hurting rice production. At the same time, this sea-water also kills off the greedy giant apple snail, an introduced pest that feeds on young rice plants. The most promising strategy has become to play one enemy off against the other.
The battle is currently being waged on land, in greenhouses at the University of Barcelona. Scientists working under the banner “Project Neurice” are seeking varieties of rice that can withstand the increasing salinity without losing the absorbency that makes European rice ideal for traditional Spanish and Italian dishes.
“The project has two sides,” says Xavier Serrat, Neurice project manager and researcher at the University of Barcelona, “the short-term fight against the snail, and a mid- to long-term fight against climate change. But the snail has given the project greater urgency.”
Originally from South America, the snails were accidentally introduced into the Ebro Delta by Global Aquatic Technologies, a company that raised the snails for fresh-water aquariums (水族馆) but failed to prevent their escape. For now, the giant apple snail’s presence in Europe is limited to the Ebro Delta. But the snail continues its march to new territory, says Serrat. “The question is not whether it will reach other rice-growing areas of Europe, but when.”
Over the next year and a half investigators will test the various strains of salt tolerant rice they’ve bred. In 2018, farmers will plant the varieties with the most promise in the Ebro Delta and Europe’s other two main rice-growing regions along the Po in Italy, and France’s Rhone. A season in the field will help determine which, if any, of the varieties are ready for commercialization.
As an EU-funded effort, the search for salt-tolerant varieties of rice is taking place in all three countries. Each team is crossbreeding a local European short-grain rice with a long-grain Asian variety that carries the salt resistant gene. The scientists are breeding successive generations to arrive at varieties that incorporate salt tolerance but retain about 97 percent of the European rice genome (基因组).
