Electronic games are often seen as a distraction from schoolwork, but now, there's a school course to study them- since this semester, Peking University has 1 an optional course called General Theory of Electronic Games, which has gained 2among students. It was 3 designed to accept 120 students, but around 200 attended the first two lessons.
However, the new course has caused a heated public debate. Some people think that as the celebrated Peking University has opened a course on electronic games, students may believe it's 4 to play games rather than 5 the research.
In response to these 6, the course teacher explained that the course isn't designed to 7 conventional view. "I like playing games, but fully 8of the problems that the games have brought about," he said. "I have a sense of 9. I want more students to know what electronic games are —their benefits and harms."
Instead of teaching students how to play electronic games, the course will 10 issues related to electronic games, such as research and development, technology and 11psychology.
This new course at Peking University arrives at a time when China's game industry is 12. China's video game market is the world's largest and is expected to continue to 13.
And the flourishing industry has 14 influenced many Chinese people, especially the young. More than 38 percent of Chinese people younger than 26 said their ideal job would be to work as a(n) 15 electronic gamer.
Despite this, a professor from Shenzhen University said it is 16 for universities and individuals to keep a 17 head in face of the market. "I hope the public can view electronic games as 18 activity and leave enough room for 19 development," he said. "Parents and teachers should also help students choose majors that can give full play to their 20.
Gemini Man
Gemini Man is a big-budget Hollywood sci-fi-action movie based on an original concept, rather than on a superhero comic or an old TV series, even though this particular original concept is more 20 years old. In it a government assassin (杀手)is being hunted down by his own clone The original script was sold by Darren Lemke to a studio in 1997, and since then almost every male A-listener has been attached as a potential star. Now, at long last, Ang Lee has directed Gemini Man, and Will Smith plays both the veteran assassin and his much younger doppelganger (分身).
Jojo Rabbit
During World War Two, a 10-year-old German boy (Roman Griffin David) is desperate to be a dutiful Nazi, only to discover that his mother (Scarlett Johansson) is hiding, a Jewish girl (Thomasin McKenzie) in their house. It may not sound like the stuff of a big-hearted comedy but Taika Waititi can make anything warm and funny. As well as writing and directing Jojo Rabbit, Waititi co-stars as the boy's imaginary friend,a nitwitted Adolf Hitler.
Doctor Sleep
Mike Flanag's new film is adapted from Stephen King, novel, Doctor Sleep, which was a sequel (续集) to The Shining. You can expect to see blood flowing out of lifts in a rapid stream, ghostly twin girls and headache-including carpet patterns. Ewan McGregor stars as Danny Torrance, the boy with psychic powers m 1980 film. Now, he is a middle-aged hospital counsellor.
Maleficent: Mistress of Evil
Here's another chance to see Angelina Jolie. In 2014 she starred in Maleficent, Disney's live-action remake of the Sleeping Beauty cartoon from 1959. The twist was that the eponymous wicked fairy wasn't so wicked, after all, and that the real villain was the father of Princess Aurora (Elle Fanning). The sequel's subtitle promises that Maleficent will actually be evil this time around, her change of heart prompted by Aurora's engagement to handsome prince (Harris Dickinson).
By analyzing the fossilized teeth of some of our most ancient ancestors, a team of scientists led by the universities of Bristol (UK) and Lyon (France) have discovered that the first humans significantly breastfed their infants (婴儿) for longer periods than their contemporary relatives.
The results, published in the journal Science Advances, provide a first insight into the practice of weaning (断奶)that remain otherwise unseen in the fossil record.
The team sampled minute amounts from nearly 40 fossilized teeth of our South African fossil relatives, early Homo, Paranthropus robustus and Australopithecus africanus. They measured the proportions of their stable calcium isotopes (同位素)in the tooth enamel(牙釉质), which are a function of the mother milk intake by infants. They show that early Homo offspring(后代) was breastfed in significant proportions until the age of around three to four years, which likely played a role in the apparition of traits that are specific to human lineage(血统), such as the brain development.
In contrast, infants of Paranthropus robustus, that became extinct around one million years ago and were a more robust species in terms of dental anatomy, as well as infants of Australopithecus africanus, stopped drinking sizeable proportions of mother milk in the course of the first months of life.
These differences in nursing behaviors likely come with major changes in the social structures of groups as well as the time between the birth of one child and the birth of the next.
One of the study's lead authors, Dr Theo Tacail said: "The practice of weaning -- the duration of breastfeeding, age at non-milk food introduction and the age at cessation of suckling -- differs among the modern members of the hominid family which includes humans and modern great apes: orangutan, gorillas, chimpanzees and bonobos.
The development of such behavioral differences likely played major roles in the evolution of the members of human lineage, being associated for instance with size and structure of social groups, brain development.
However, getting insights into these behavioral changes from fossils that are millions of years old is a challenge and, so far, little evidence allow discussing nursing practices in these fossil species.
The findings stress the need for further exploration of calcium stables isotopes compositions in the fossil record in order to understand the co-evolution of weaning practices with other traits such as brain size or social behaviors."

FaceApp has taken the world by storm, giving users the chance to see themselves age through its algorithm. 12.7 million people—some three million more than the population of New York City—reportedly downloaded it in one seven-day period last month.
Although the Russian app has become known for its privacy issues, the more interesting lesson of our FaceApp fling (尽情玩乐)is what it tells us about our society—and our future lives. It turns out we are more interested in aging than we realized. I'm surprised by this. Most younger people are in denial (否认)about old age, doing almost nothing to prepare for it. We rarely have a chance to plan for the future, with increasing time and financial pressures. Those pressures bring sacrifices that we may not always want to make: we can no longer afford to spend the time or the money needed to look after our elderly parents.
As a family doctor, I can see the loneliness epidemic developing. Elderly patients come to see me with no particular illness, no clear medical issue. After a few minutes of the consultation, I understand why: they're not sick, and often they don't feel sick. They just need someone—anyone-to talk to.
Although loneliness has no medical classification, the health effects are real: the result of loneliness and isolation can be as harmful to our health as smoking 15 cigarettes a day, and is more damaging than obesity. But loneliness does not come with nearly enough health warnings.
So what next? Since 1980, we are living on average 10 years longer. At the same time, people are having fewer and fewer children, and they are having them much later in life. The snake of a world class health service is eating its own tail; its care is prolonging (延长) people's lives, but as the ratio of pensioners(退休人员)to working -age people increases, there are fewer taxpayers to fund that very health service.
Into this void have stepped NGOs, charities and volunteers. But in the long term, the only way to truly help the oldest meters of our society is to go back to the traditional values of intergenerational(两代间的) cooperation—often under same roof. Ultimately, we will need to evolve towards a culture where elderly care is treated the same as childcare, where employers recognize the duty of someone with an elderly parent the same way they recognize those of someone with a newborn child.
Microsoft announced this week that its facial-recognition system is now more accurate in identifying people of color, touting (吹嘘)its progress at tackling one of the technology's biggest biases (偏见).
But critics, citing Microsoft's work with Immigration and Customs Enforcement, quickly seized on how that improved technology might be used. The agency contracts with Microsoft for cloud-computing tools that the tech giant says is largely limited to office work but can also include face recognition.
Columbia University professor Alondra Nelson tweeted, "We must stop confusing 'inclusion' in more 'diverse' surveillance (监管)systems with justice and equality."
Facial-recognition systems more often misidentify people of color because of a long-running data problem: The massive sets of facial images they train on skew heavily toward white men. A Massachusetts Institute of Technology study this year of the face-recognition systems designed by Microsoft, IBM and the China-based Face++ found that facial-recognition systems consistently giving the wrong gender for famous women of color including Oprah Winfrey, Serena Williams, Michelle Obama and Shirley Chisholm, the first black female member of Congress.
The companies have responded in recent months by pouring many more photos into the mix, hoping to train the systems to better tell the differences among more than just white faces. IBM said Wednesday it used 1 million facial images, taken from the photo-sharing site Flickr, to build the "world's largest facial data-set" which it will release publicly for other companies to use.
IBM and Microsoft say that allowed its systems to recognize gender and skin tone with much more precision. Microsoft said its improved system reduced the error rates for darker-skinned men and women by "up to 20 times," and reduced error rates for all women by nine times.
Those improvements were heralded(宣布)by some for taking aim at the prejudices in a rapidly spreading technology, including potentially reducing the kinds of false positives that could lead police officers misidentify a criminal suspect.
But others suggested that the technology's increasing accuracy could also make it more marketable. The system should be accurate, "but that's just the beginning, not the end, of their ethical obligation," said David Robinson, managing director of the think tank Upturn.
At the center of that debate is Microsoft, whose multimillion-dollar contracts with ICE came under fire amid the agency's separation of migrant parents and children at the Mexican border.
In an open letter to Microsoft chief executive Satya Nadella urging the company to cancel that contract, Microsoft workers pointed to a company blog post in January that said Azure Government would help ICE "accelerate recognition and identification." "We believe that Microsoft must take an ethical stand, and put children and families above profits," the letter said.
A Microsoft spokesman, pointing to a statement last week from Nadella, said the company's "current cloud engagement" with ICE supports relatively anodyne(温和的)office work such as "mail, calendar, massaging and document management workloads." The company said in a statement that its facial-recognition improvements are "part of our going work to address the industry-wide and societal issues on bias."
Criticism of face recognition will probably expand as the technology finds its way into more arenas, including airports, stores and schools. The Orlando police department said this week that it would not renew its use of Amazon. com's Rekognition system.
Companies "have to acknowledge their moral involvement in the downstream use of their technology,"
Robinson said. "The impulse is that they're going to put a product out there and wash their hands of the consequences. That's unacceptable."
If there is one word to describe the progress made in the last 100 years, it's connectedness. From the telephone to the radio to the TV to the Internet, we have found ways to bring us all closer together, enabling,constant worldly access.
I don't think I need to highlight the benefits of all this. But the downsides are also beginning to show. Beyond the current talk about privacy and data collection, there is perhaps an even more detrimental side-effect here: We now live in a world where we're connected to everything except ourselves. According to Pascal, we fear the silence of existence, and we dread boredom and instead choose aimless distraction and use the noise of the world to block out the discomfort of dealing with ourselves.
However, we ignore the fact that never facing ourselves is why we feel lonely an anxious in spite of being so intimately connected to everything else around us.
Fortunately, there is a solution. The only way to avoid being ruined by this is to face it. It's to let the boredom take you where it wants so you can deal with whatever it is that is really going on with your sense of self. That's when you'll hear yourself think, and learn to engage the parts of you that are masked by distraction.
The beauty of this is that, once you cross that initial barrier, you realize that being alone isn't so bad. Boredom can provide its own stimulation.
When you surround yourself with moments of solitude and stillness, you become intimately familiar with your environment in a way that forced stimulation doesn't allow. The world becomes richer, the layers start to peel back, and you see things for what they really are, in all their wholeness, in all their contradictions, and in all their unfamiliarity.
You learn that there are things you are capable of paying attention to than just what makes the most noise on the surface. Just because a quiet room doesn't scream with excitement like the idea of immersing yourself in a movie or a TV show doesn't mean there isn't depth to explore there.
Sometimes, the direction that this solitude leads you in can be unpleasant, especially when it comes to introspection (内省)—your thoughts and your feelings, your doubts and your hopes—but in the long term, it's far more pleasant than running away from it all without even realizing what you are.
Being alone and connecting inwardly is a skill nobody ever teaches us. That's ironic because it's more important than most of the ones they do.
Solitude may not be the solution to everything, but it certainly is a start.

Did you go somewhere for your Spring Festival holiday? Did you get lost in the crowds and become one of hundreds or thousands of people crammed together in front of a building, a landscape, a bridge or even a painting? This is what we call "overtourism"—the phenomenon of a popular destination or sight becoming overrun with tourists in an unsustainable way.
Overtourism occurs when there are too many visitors to a particular destination. "Too many" is a subjective term, of course, but it is defined in each destination by local residents, hosts, business owners and tourists. When rent prices push out local tenants to make way for holiday rentals, that is overtourism. When narrow roads become jammed with tourist vehicles, that is overtourism. When wildlife is scared away, when tourists cannot view landmarks because of the crowds, when fragile environments become degraded—these are all signs of overtourism.
These years, the travel industry focuses almost exclusively on growth, with little or no concern for the impacts. In many destinations, tourism now demonstrably creates more problems than benefits. This can take many forms; perhaps a million additional tourists are arriving in a capital city, or 20 additional tourists in a small, rural community.
And whenever you travel, try and ensure as much of your cash stays as local as possible. Pay national park entrance fees to ensure your visit supports conservation; stay in locally owned guesthouses; eat at local restaurants and take tours with local guides. Tourism can still be very much a force for good, and ensuring that local residents, habitats and wildlife benefit from your presence is an important part of that.
