1 . Think back to when you were in a maths classroom, and the teacher set a difficult problem. Which of the two following responses is closer to the way you reacted?
A: Oh no, this is too hard for me. I’m not even going to seriously try and work it out.
B: Ah, this is quite tricky, but I like to push myself. Even if I don’t get the answer right, maybe I’ll learn something in the attempt.
Early in her career, the psychologist Carol Dweck of Stanford University gave a group of ten-year-olds problems that were slightly too hard for them. One group reacted positively and loved the challenge. She says they had a ‘growth mindset’ and are focused on what they can achieve in the future. But another group of children felt that their intelligence was being judged and they had failed. They had a ‘fixed mindset’ and were unable to imagine improving. Some of them looked for someone who had done worse than them to boost their self-esteem.
Professor Dweck believes that there is a problem in education at the moment. For years, children have been praised for their intelligence or talent, but this makes them vulnerable (脆弱的) to failure. They become performance-oriented, wanting to please by getting high grades, but they are not interested in learning for its own sake. The solution, according to Dweck, is to lead them to become mastery-oriented (i.e., interested in getting better at something). She claims that the ever-lasting effort over time is the key to outstanding achievement.
Psychologists have been testing these theories. Underperforming school children on a Native American reservation were exposed to growth mindset techniques for a year. The results were nothing less than incredible. They came top in regional tests, beating children from much more privileged backgrounds. These children had previously felt that making an effort was a sign of stupidity, but they came to see it as the key to learning.

2 . Gone are the days when a mother’s place was in the home: in Britain women with children are now as likely to be in paid work as their unburdened sisters. Many put their little darlings in day care long before they start school. Mindful that a poor start can spoil a person’s chances of success later in life, the state has intervened ever more closely in how babies and toddlers are looked after. Inspectors call not only at nurseries but also at homes where youngsters are minded; three-year-olds follow the national curriculum. Child care has increasingly become a profession.
For years after the government first began in 2001 to twist the arms of anyone who looked after an unrelated child to register with the schools, the numbers so doing fell. Kind but clueless neighbours stopped looking after little ones, who were instead herded into formal nurseries or handed over to one of the ever-fewer registered child-minders. The decline in the number of people taking in children now appears to have halted. According to data released by the Office for Standards in Education on October 27th, the number of registered child-minders reached its lowest point in September 2010 and has since recovered slightly.
The new lot are certainly better qualified. In 2010 fully 82% of nursery workers held diplomas notionally equivalent to A-levels, the university-entrance exams taken mostly by 18-year-olds, up from 56% seven years earlier, says Anand Shukla of the Daycare Trust, a charity. Nurseries staffed by university graduates tend to be rated highest by inspectors, increasing their appeal to the pickiest parents. As a result, more graduates are being recruited.
But professionalization has also pushed up the price of child care, defying even the economic depression. A survey by the Daycare Trust finds that a full-time nursery place in England for a child aged under two, who must be intensively supervised, costs £194 ($310) per week, on average. Prices in London and the south-east are far higher. Parents in Britain spend more on child care than anywhere else in the world, according to the OECD, a think-tank. Some 68% of a typical second earner's net income is spent on freeing her to work, compared with an OECD average of 52%.
The price of child care is not only eye-watering, but has also become a barrier to work. Soon after it took power the coalition government pledged to ensure that people are better off in work than on benefits, but a recent survey by Save the Children, a charity, found that the high cost of day care prevented a quarter of low-paid workers from returning to their jobs once they had started a family. The government pays for free part-time nursery places for three-and four-year-olds, and contributes towards day-care costs for younger children from poor areas. Alas, extending such an aid during stressful economic times would appear to be anything but child’s play.

3 . Revealing the source of Jupiter’s x-ray auroral flares
Abstract
Jupiter’s rapidly rotating, strong magnetic field provides a natural laboratory that is key to understanding the dynamics (动力学) of high-energy plasmas (等离子体). Spectacular auroral (极光的) X-ray flares (耀斑) are diagnostic of the most energetic processes governing magnetospheres but seemingly unique to Jupiter. Since their discovery 40 years ago, the processes that produce Jupiter’s X-ray flares have remained unknown. Here, we report simultaneous (同时的) in situ satellite and space-based telescope observations that reveal the processes that produce Jupiter’s X-ray flares, showing surprising similarities to terrestrial ion aurora. Planetary-scale electromagnetic waves are observed to modulate (调节) electromagnetic ion cyclotron waves, periodically causing heavy ions to precipitate and produce Jupiter’s X-ray pulses. Our findings show that ion aurorae share common mechanisms across planetary systems, despite temporal, spatial, and energetic scales varying by orders of magnitude.
INTRODUCTION
Aurorae, observed from planetary polar regions across the solar system, are displays of light that are produced when energetic particles precipitate along magnetic field lines and transfer their energy to the atmosphere. Jupiter’s soft x-ray aurorae are produced by energetic [~ (MeV) (电子伏)] heavy ions (S and O), originally from the moon Io’s (木卫一的) volcanic activities. The dynamic X-ray emissions often pulse with a regular beat of a few tens of minutes. The spectacular quasi-periodic (准周期性的) auroral pulsations at Jupiter have also been observed in ultraviolet (UV), infrared, and radio emissions. The X-ray aurorae are predominately confined (主要局限于) to the region poleward of Jupiter’s main aurora, connecting to Jupiter’s outer magnetosphere via magnetic field lines. The mapping of the emissions leads to the suggestion that the particle precipitations were driven by magnetic reconnection. However, observations show that the x-ray pulsations last for several Jupiter days or longer, evidencing that the driver may not be a transient process like magnetic reconnection.
To date, 40 years after their discovery, the mechanisms that cause these X-ray aurorae remain unknown. Simultaneous measurements of the magnetospheric environment and the auroral emissions are critical to revealing their driving mechanisms. Here, we present observations of Jupiter’s unique x-ray aurorae with simultaneous in situ measurements from the magnetosphere. In this study, we reveal the physical driver for Jupiter’s pulsating x-ray emissions by analyzing simultaneous in situ measurements from Juno and remote spectroscopic imaging by XMM-Newton telescope (XMM，牛顿卫星) during 16 and 17 July 2017. XMM’s European Photon Imaging Camera (EPIC-pn and MOS) instruments provided spatial, spectral, and timing data of Jupiter for a continuous 26-hour (~2.6 Jupiter rotations) observation from 18:26 UT on 16 July to 22:13 UT on 17 July, which was shifted to account for the ~46-min light travel time between Jupiter and Earth. This XMM observation was planned to coincide with the time when NASA’s Juno spacecraft was moving from 62 to 68 RJ (1 RJ = 71 492 km) radially away from the planet in the Southern Hemisphere in the predawn sector between ~0400 and 0430 magnetospheric local time (MLT).
Ionosphere-magnetosphere (电离层) mapping from previous observations suggested that the origins of Jupiter’s X-ray auroral pulsations occurred at these distances from the planet. Juno provided contemporaneous (同时发生的) in situ measurements from the plasma sheet only when Jupiter’s north magnetic pole tilted to Earth. Therefore, we focus on the northern aurora, for which Juno’s in situ measurements detail what was happening in the plasma sheet during the X-ray pulses. At Jupiter, the analysis of these comparisons between in situ and remote sensing observations is more complex than at Earth. At Earth, during the time scale of an auroral event, typically tens of minutes, a spacecraft in the terrestrial magnetosphere usually travels little (e.g., hundreds of kilometers) in comparison to the spatial scale of a magnetospheric event (e.g., several Earth radii) that would cause a large auroral brightening so that this in situ spacecraft could be magnetically connected to the aurora region over the full auroral lifetime. This is not true for Jupiter, because the footprint of the aurora (which is rotating with Jupiter) with respect to Juno’s location changes substantially during an observation. There are also substantial travel times (a few tens of minutes) along the magnetic field expected from the outer magnetosphere to the Jovian aurora. Therefore, the correlation between a single outer magnetosphere event in Jupiter’s in situ measurements and a single auroral pulse cannot be expected on a one-to-one level basis. Instead, a series of successive events are required to draw reliable careful correlations, with the regular periodicity of the x-ray flares, providing an invaluable diagnostic signature of the source process.

5 . Feeling achy and feverish? Your misery has plenty of company. By the end of December, the tally (计数器) of flu-like illnesses in the state exceeded the peaks in the two previous seasons, when the biggest number of cases occurred in February and March. This time, the flu virus seems to be hitting even harder.
Flu is unique among human diseases. It circulates constantly in cool and dry areas. Because it spreads from person to person and can be picked up easily, nearly everyone is exposed. While it’s unclear whether the annual flu epidemic (流行病) will worsen this year, or just arrived earlier, fears have been increased by the severity of flu in Australia during its most recent season and the fact that the vaccine may protect against the predominant (盛行的) kind of the flu only 30 percent of the time.
Despite the worries, doctors and public health officials say there is no evidence that people are getting sicker than usual. Flu cases in Massachusetts started rising around Thanksgiving and increased steadily, with an especially steep climb in the last week of the year. “This is a bad flu season but not a horrible one,” said Dr. Andrew G. Villanueva, a lung specialist and chief quality officer at the Lahey Hospital & Medieal Centre in Burlington.
The flu season, while clearly in full swing, doesn’t “feel different” from previous years, Villanueva said. “We’re not seeing a lot of people being hospitalized because of flu,” he said. “Most people with the flu recover on their own without medical care.”

6 . A robot created by Washington State University (WSU) scientists could help elderly people with dementia (痴呆) and other limitations live independently in their own homes.
The Robot Activity Support System, or RAS, uses sensors installed in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with daily activities. It navigates (定位) through rooms and around obstacles to find people on its own, provides video instructions on how to do simple tasks and can even lead its owner to objects like their medication or a snack in the kitchen.
“RAS combines the convenience of a mobile robot with the activity detection technology of a WSU smart home to provide assistance in the moment, as the need for help is detected,” said Bryan Minor, a postdoctoral researcher in the WSU School of Electrical Engineering and Computer Science.
Currently, an estimated 50 percent of adults over the age of 85 need assistance with every day activities such as preparing meals and taking medication and the annual cost for this assistance in the US is nearly $2 trillion. With the number of adults over 85 expected to triple by 2050, researchers hope that technologies like RAS and the WSU smart home will relieve some of the financial strain on the healthcare system by making it easier for older adults to live alone.
RAS is the first robot researchers have tried to incorporate into their smart home environment. They recently published a study in the journal Cognitive Systems Research that demonstrates how RAS could make life easier for older adults struggling to live independently.
“While we are still in an early stage of development, our initial results with RAS have been promising,” Minor said. “The next step in the research will be to test RAS’ performance with a group of older adults to get a better idea of what prompts, video reminders and other preferences they have regarding the robot.”

7 . Is there a way to turn back the aging process in people? For centuries, people have been looking for a “fountain of youth.” The idea is that if you find a magical fountain, and drink its water, you will not age.
Researchers in New York did not find an actual fountain of youth, but they may have found a way to turn back the aging process. It appears that the answer may be called the hypothalamus, which is part of your brain. It controls important body activities, including growth, the way we process food and so on. Researchers found that hypothalamus neural stem cells (干细胞) also influence how fast aging takes place.
Dongsheng Cai was the leading researcher in a study on aging in mice. He and his team reported their findings. “when the hypothalamus starts aging, particularly the loss of hypothalamus stem cells, so does the body.” he said.
Using this information, the researchers began trying to activate (激活) the hypothalamus in laboratory mice. The results show that the treatment slowed aging in the animals. “When we injected the hypothalamus stem cells to the middle-aged mice, the mice aged slowly and they could also live longer.”
But these results were just from studying mice in a laboratory. If the mice can live longer, does that mean people could have longer lives? The next step is to see if the anti-aging effects also work in human beings. If so, they say the findings could lead to new ways to help doctors identify and treat age-related health problems.

8 . It’s not just adults who have a thing or two to discuss with other people, babies too have their own social lives and enjoy group interaction, according to a world-first study.
The breakthrough study conducted by psychologist Professor Ben Bradley, at Charles Sturt University, could completely transform the way child-care centres are set up. In their study, the researchers examined groups of nine-month-old babies in New South Wales and Britain.
And they came across astounding(令人吃惊的) results. It was found that infants had “social brains” and focused not just on their mothers but on social life in groups as well.
“They communicate with more than one baby at once, and show jealousy and generousness,” said Professor Bradley.
He added, “They develop their own meanings through group interaction, they notice if a group member is behaving differently and they take on roles, such as leaders and followers.”
“A baby who has a depressed mother tends to be withdrawn ( 内 向 的 ), but put that same baby in a group of its peers (同龄人) and they behave and interact like any other baby.”
It was the first all-baby group study ever to be conducted. “Most studies of babies concentrate on the infant-mother relationship, assuming that is the single foundation for mental health, but babies are constantly involved with groups of people other than their mothers, fathers, siblings, grandparents and those taking care. Therefore, the mother-baby approach needs to be combined with a group approach,” said Bradley.
Phoebe Christison, a child-care worker at Camperdown Sunshine Bubs in Sydney’s inner west, said she often noticed what appeared to be emotional attachments developed between toddlers.
She said, “Joel （ 1 ） months ) and Isabella （ 2 ） months ) always like to hold hands when they sit in their high chairs and eat. And babies definitely show jealousy. They push and touch each other, and copy what the other is doing.”
1. Which of the following statements about the study is TRUE?| A．It’s the first study to look at all-baby groups. |
| B．It divides babies according to their personalities. |
| C．Its aim is to change the way of child care. |

| C．has poor social ability | D．pays more attention to its mother |
| A．There’s no need of child-care centers at all. |
| B．Babies are affected by groups more than by their mothers. |
| C．Adults should include babies when having social activities. |
| D．The normal infant-mother bond alone isn’t enough for the good mental health for babies. |
| A．adults | B．infants |

9 . If we want to find out what kind of technology people used in the past, we normally have to rely on archaeologists to find ruined buildings and parts of tools or instruments or machines. Archaeologists then try to reconstruct, sometimes with the help of computer technology, what these ancient buildings and objects must have looked like, and how they might have been made. Sometimes historians are lucky and find an ancient document with a written description of these ancient buildings and objects.
We can understand, then, why Chinese historians were so excited when they found cave paintings which show ancient science. They found these paintings in the world-renowned Mogao Grottoes of Dunhuang City, in Northwest China's Gansu Province. There are 500 man-made caves and they have survived for at least 1,600 years. Almost all of these caves have paintings on their ceilings or walls and they date from the 4th to 14th centuries. Wang Jinyu is an expert on these cave paintings (also called frescoes) and he says: “We discovered frescoes containing scientific and technological content in almost all of the caves which have frescoes.” What is remarkable about these cave paintings according to the Xinhua News Agency is that they provide evidence of "scientific and technological inventions by ancient Chinese in maths, physics, chemistry, astronomy, geography, agronomy, architecture, textiles, traffic and transportation, arms and military equipment and medical sciences".
Among the discoveries experts have made are cave paintings showing ancient techniques of pottery making and wine production and paintings showing ancient weaving machines and then toothbrushes! The paintings also give some evidence of the lifestyle at the time with, for example, pictures of people boiling milk over 1,000 years ago. Experts believe that there is more evidence to be found, but even now the caves are a wonderful natural museum. If the walls and ceilings of the caves were all put together they would form a tapestry 20 kilometers long and 2 meters high!
It won't be possible to travel back in time-that only happens in films-but visiting these caves would be the nearest experience you could get to travelling back in time.

10 . Some of the greatest moments in human history were fueled by emotional intelligence. When Martin Luther King. Jr. presented his dream, he chose language that would stir the hearts of his audience. Delivering this electrifying(震撼性的) message required emotional intelligence—the ability to recognize, understand, and manage emotions.
Emotional intelligence has been highly recommended by leaders, policymakers, and educators as the solution to a wide range of social problems. If we can teach our children to manage emotions, the argument goes, we'll have less bullying and more cooperation. If we can cultivate emotional intelligence among leaders and doctors, we'll have more caring workplaces and more compassionate healthcare.
Emotional intelligence is important, but the uncontrolled enthusiasm has obscured (掩盖)a dark side. New evidence shows that when people sharpen their emotional skills, they become better at manipulating (把持) others. When you're good at controlling your own emotions, you can hide your true feelings. When you know what others are feeling, you can motivate them to act against their own best interests.
Social scientists have begun to document this dark side of emotional intelligence. In a research led by University of professor Jochen Menges, when a leader gave an inspiring speech filled with emotion. the audience was less likely to scrutinize (细察) the message and remembered of the content. Ironically(讽刺的是) audience members were so moved by the speech that they claimed to recall more of it.
The authors call this the awestruck effect, but it might just as easily be described as the dumbstruck effect. One observer reflected that Hitler's persuasive impact came from his ability to strategically express emotions—he would "ear open his heart—and these emotions affected his followers to the point that they would"stop thinking critically and just emote.”
Leaders who master emotions can rob us of our capacities to reason. If their values are out of step with our own. the results can be destructive. New evidence suggests that when people have self-serving motives (动机), emotional intelligence becomes a weapon for manipulating others. In a study led by the University of Toronto psychologist Stephane Cote, university employees filled out a survey about their Machiavellian(不择手段的) tendencies, and took a test measuring their knowledge about effective strategies for managing emotions. Then, Cote's team assessed how often the employees deliberately undermined (逐渐削弱) their colleagues. The employees involved in the most harmful behaviors were Machiavellians with high emotional intelligence. They used their emotional skills to lower the dignity of their peers for personal gain.
Shining a light on this dark side of emotional intelligence is one mission of a research team led University College London professor Martin Kilduff. According to these experts, emotional intelligence helps people disguise (伪装) one set of emotions while expressing another for personal Professor Kiiduit's team writes,""The strategic disguise of one's own emotions and the manipulation of others' emotions for strategic ends are behaviors evident not only on Shakespeare's stage but also in the offices and corridors where power and influence are traded.”
Of course, people aren't always using emotional intelligence for nefarious ends. More often than not, emotional skills are simply instrumental tools for goal accomplishment. A research team discovered that founder Anita Roddick used emotional intelligence to inspire her employees fundraise for charity. As Roddick explained, "Whenever particular project we always tried to break their hearts we wanted to persuade our staff to support a particular project we always tried to break their hearts.”
There is growing recognition that emotional intelligence--like any skill--can be used for good or evil. So if we're going to teach emotional intelligence in schools and develop it at work, we need to consider the values that go along with it and where it's actually useful.
