1 . Endangered polar bears are breeding (繁殖) with grizzly bears (灰熊), creating “pizzly” bears, which is being driven by climate change, scientists say.
As the world warms and Arctic sea ice thins, starving polar bears are being forced ever further south, where they meet grizzlies, whose ranges are expanding northwards. And with that growing contact between the two come increasing hybrids (杂交种).
With characteristics that could give the hybrids an advantage in warming northern habitats, some scientists guess that they could be here to stay. “Usually, hybrids aren’t better suited to their environments than their parents, but these hybrids are able to search for a broader range of food sources,” Larisa DeSantis, an associate professor of biological sciences at Vanderbilt University, told Live Science.
The rise of “pizzly” bears appears with polar bears’ decline: their numbers are estimated to decrease by more than 30% in the next 30 years. This sudden fall is linked partly to “pizzly” bears taking up polar bears’ ranges, where they outcompete them, but also to polar bears’ highly specialized diets.
“Polar bears mainly consumed soft foods even during the Medieval Warm Period, a previous period of rapid warming,” DeSantis said, referring to fat meals such as seals. “Although all of these starving polar bears are trying to find alternative food sources, like seabird eggs, it could be a tipping point for their survival.” Actually, the calories they gain from these sources do not balance out those they burn from searching for them. This could result in a habitat ready for the hybrids to move in and take over, leading to a loss in biodiversity if polar bears are replaced.
“We’re having massive impacts with climate change on species,” DeSantis said. “The polar bear is telling us how bad things are. In some sense, “pizzly” bears could be a sad but necessary compromise given current warming trends.”

2 . Sports can help contribute to a healthy body and get you close to nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great impact on the environment.
There are many environment-friendly sports.
Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces.

3 . Ai-Da sits behind a desk, a paintbrush in her hand. She looks up at the person posing for her, and then back down as she applies another drop of paint onto the canvas(画布). A lifelike portrait is taking shape. If you didn’t know a robot produced it, this portrait could pass as the work of a human artist.
Ai-Da produces portraits of sitting subjects using a robotic hand attached to her lifelike figure. She’s also able to talk, giving detailed answers to questions about her artistic process and attitudes towards technology. She even gave a TEDx talk titled “The Intersection of Art and AI” in Oxford several years ago. Ai-Da’s creators have also been experimenting with having her write and perform her own poetry.
But how are we to interpret Ai-Da’s output? Should we consider her paintings and poetry original and creative? Are these works actually art?
What discussions about AI and creativity often overlook is the fact that creativity isn’t an absolute quality that can be defined, measured and reproduced objectively. When we describe an object-for instance, a child’s drawing—as being creative, we project our own assumptions about culture onto it. Indeed, art never exists in isolation. It always needs someone to give it “art” status. And the criteria for whether you think something is art are formed by both your expectations and broader cultural conceptions.
If we extend this line of thinking to AI, it follows that no Al application or robot can objectively be “creative”. It is always we—humans—that decide whether works created by AI are art.
Some may see robot-produced paintings as something coming from creative computers, while others may be skeptical, given the fact that robots act on clear human instructions. In any case, attribution (归属)of creativity never depends on technical arrangement alone—no computer is objectively creative. Rather, the attribution of computational creativity is largely inspired by contexts of reception. Through particular social information, some people are inspired to think of AI output as art, systems as artists, and computers as creators. Therefore, as with any piece of art, your appreciation of AI output ultimately depends on your own interpretation.

C.Four eyes see more than two. | D.Beauty is in the eye of the beholder. |
A.Is AI-created Art Really Art? | B.Will People Accept AI Artists? |

I live in a city where jobs are difficult to get and if you want to find a well-paid job, it will be even harder. Therefore, it is not surprising for you to see many people in our city walk a long way because they can’t even afford an old used car.
It was a cold windy day. I saw one of these people who often have to walk from and to work every day, when I was driving after work. A middle-aged man wearing only a thin overcoat was walking down the road and trying to ask for a ride from the passing cars. Unluckily, there was no driver willing to stop their cars. When I saw two cars in front of me pass him by, I wanted to do the same. But the sight of that poor man remained in my mind for quite a moment. I felt as if a big hand was dragging me and forcing me not to leave. Finally I drew back and gave him a ride.
As I drove along, we had a conversation, during which he told me something about himself and his family. I learnt that the man was doing everything he could to support his family using the limited salary from several part-time jobs. As you could imagine, every coin he earned was going to be used to pay for the house and food.
It was a long drive before we got to his home. All the way, I could feel his hardship and tiredness. But as we came close to the house where he was living, I saw his tired eyes grow bright and the whole body was lit up. His lovely girl was playing in the front yard. Seeing her father was out of the car, she ran to him as quickly as possible, reaching out her two small hands. He held the girl with his two strong hands, laughing and kissing her cheeks. I was lost in that happy moment. I smiled, said goodbye to them, wished them the future happiness and then drove off.

Learning that the captain of the ship, the Beagle, wanted someone who would like to have the opportunity of visiting distance countries yet little known, a young man answered the call. Obviously, he was not the captain’s first choice. That was why he had left medical school without completing his degree. In addition to, he had recently received a letter from his father predicting he would be a disgrace to himself and all his family. Despite all this, his adventures on this ship will lead to one of the most important scientific discoveries of all time.
The young man in question was Charles Darwin,a geologist and naturalist, fascinating by rocks, plants and animals. He had his room on the ship crowded with samples of the plants and animals he had collected. Studying these, he wondered what different species came to exist.
After noticing some species of animals were similar to each other, he came up an idea that maybe animals evolved as they adapted to their changing environments.
It was such new an idea that nobody believed him. But they refused to believe that living things, including humans, had evolved from lower form of life.
6 . Everyone who uses a smartphone unavoidably produces masses of digital data that are accessible to others, and these data provide clues to the user’s personality. Psychologists in Munich (LMU) are studying how revealing these clues are.
For most people around the world, smartphones have become an important part of their daily lives. The digital data that these devices constantly collect are a goldmine-not only for the five largest American IT companies, which make use of them for advertising purposes. They are also of considerable interest in other contexts. For instance, computational social scientists use smartphone data in order to learn more about personality and social behavior. In a study that appears in the journal PNAS, a team of researchers led by LMU psychologist Markus Buhner set out to determine whether data collected by smartphones (such as times or frequencies of use) provide deep understanding of users’ personalities.
The LMU team organized 624 volunteers for their Phone Study project. The participants agreed to fill out an extensive questionnaire describing their personality, and to install an App that had been developed specially for the study on their phones for 30 days. The App was designed to collect coded information relating to the behavior of the user. The automated analysis showed that the method was indeed able to successfully get most of these personality traits from their smartphone usage.
Clemens Stachl is aware that his research might further inspire the big IT firms for data. He says, “the potential of these applications-in both research and business-is very great. The opportunities opened up by today’s data-driven society will undoubtedly improve the lives of large numbers of people. But we must ensure that all sections of the population share the benefits offered by digital technologies.”
