1 . Artificial intelligence (AI) plays an important role in the Asian Games Hangzhou 2022 and Asian Para Games. AI usually refers to the advanced technologies, such as the naked-eye 3D, VR, AR and so on. These terms might sound familiar, but how smart are they when applied to the 56 Asian Games venues (场地)?

Their smartness can be found in running the venues with less human labor forces and with more connections between man and machines. At the Huanglong Sports Center, a system called Smart Stadium Brain is 1debuilt. The Brain, a 25-square-meter high-definition screen in the venue’s information center, displays the entire venue in 3D visualization to keep an eye on the temperature, the lighting, the energy consumption, and the facilities to ensure a friendly environment for the athletes and audiences. For the benefit of audiences, a small screen on each seat is designed to be at the audience’s service. By finger touching, the audience can control it from three parts—angle, speed, and size to watch and keep contact with the event. What’s more, supported by the 5G technology, a 360° playback function is fixed.   

AI also means further protection on environment. At the Fuyang sports Center, although it has been raining for days, the roof of the venue still remains dry. And the secret lies in its attractive sky garden. The garden, covering the roof, is not only eye-catching but also useful. It allows the greening rate of the entire stadium to reach as high as 45%, being energy-saving. Under the cobblestones (鹅卵石) of the sky garden, a recovery system is filtering (过滤) and collecting rainwater for the venue’s water system, fountain, and irrigation water.

Smart devices are employed both inside and outside the venues. For example, the Tonglu sports Center starts a WeChat mini-program for any follower to learn about the venue through VR games and videos before the Hangzhou Asian Games. During the Games, the program will allow the athletes and audiences to place orders online, waiting in the venue for a robot waiter to deliver and serve their food.

2 . Is future you? It might seem like a strange philosophical question. But the answer to how you think about your future self could make the difference between decisions you ultimately find satisfying and ones you might eventually regret.

The brain patterns that emerge on an MRI (核磁共振成像) when people think about their future selves most like the brain patterns that arise when they think about strangers. This finding suggests that, in the mind’s eye, our future selves look like other people. If you see future you as a different person, why should you save money, eat healthier or exercise more regularly to benefit that stranger?

However, if you see the interests of your distant self as more like those of your present self, you are considerably more likely to do things today that benefit you tomorrow. A paper in the journal PLoS One revealed that college students who experienced a greater sense of connection and similarity to their future selves were more likely to achieve academic success. Relationships with our future selves also matter for general psychological well-being. In a project led by Joseph Reiff, which includes 5, 000 adults aged 20 to 75, he found that those who perceived a great overlap (重叠) in qualities between their current and future selves ended up being more satisfied with their lives 10 years after filling out the initial survey.     

So how can we better befriend our future selves and feel more connected to their fates? The psychological mindset with what we call ”vividness interventions“ works. We have found, for instance, that showing people images of their older, grayer selves increases intentions to save for the long term. Besides, you might try writing a letter to-and then from-your future self. As demonstrated by Yuta Chishima and Anne Wilson in their 2020 study in the journal Self and Identity, when high-school students engaged in this type of ”send-and-reply“ exercise, they experienced elevated (升高的) levels of feelings of similarity with their future selves.

Letter-writing and visualization exercises are just a couple of ways we can connect with our future selves and beyond, but the larger lesson here is clear: If we can treat our distant selves as if they are people we love, care about and want to support, we can start making choices for them that improve our lives-both today and tomorrow.

5 . There is a song by the great Jamaican singer Bob Marley called So Much Trouble in The World. Marley understood that part of the reason why there are so many problems in the world is the lack of tolerance between people. The UN understands this too— that is why it made November 16th “International Day for Tolerance”.

But first, what is tolerance? According to French philosopher Voltaire, “Tolerance is the consequence of humanity. We are all formed of frailty (脆弱) and error; let us pardon each other’s fool— that is the first law of nature.”

Very often, people do not realize that they are intolerant. This is because intolerance has a lot to do with ignorance. For example, the UN’s campaign is in part about the treatment of females by males. But often, the behavior of men toward women is intolerant because men do not put themselves in the shoes of women.

It is worth thinking a little about the words “tolerance” and “intolerance”. Are they the best words to describe the evils of which we are speaking here? To agree to be “tolerant” of someone is not necessarily a very respectful thing. When someone is tolerated, it implies that there is something wrong with them.

Still, what Voltaire said stands: We humans are not perfect and this weakness is something that we all share. That is the reason we should be tolerant. It is a little like generosity. We can give things to another person, and we can also give our forgiveness.

6 . Plants cannot run or hide, so they need other strategies to avoid being eaten. Some curl up their leaves, others produce chemicals to make themselves taste bad if they sense animals drooling on them, chewing them up or laying eggs on them—all signals of an attack. New research now shows some flora can feel a plant-eating animal well before it launches an attack, letting a plant prepare a preemptive（先发制人的）defense that even works against other pest species.

When ecologist John Orrock of the University of Wisconsin-Madison sprayed snail slime—a liquid the animals release as they slide along—onto soil, nearby tomato plants appeared to notice. They increased their levels of an enzyme（酶）, which is known to prevent plant-eating animals. “None of the plants were ever actually attacked,” Orrock says. “We just gave them cues that suggested an attack was coming, and that was enough to cause big changes in their chemistry.”

Initially Orrock found this defense worked against snails; in the latest study, his team measured the slimy warning’s impact on another potential threat. The investigators found that hungry caterpillars（毛虫）, which usually eat tomato leaves greedily, had no appetite for them after the plants were exposed to snail slime and activated their chemical resistance. This nonspecific defense may be a strategy that benefits the plants by further improving their overall possibilities of survival, says Orrock, who reported the results with his colleagues in March in Oecologia.

The finding that a snail’s approach can cause a plant response that affects a different animal made Richard Karban curious, a plant communications expert, who was not involved in the study. “It is significant that the plants are responding before being damaged and that these cues are having such far-ranging effects, ” Karban says. The research was comprehensive, he adds, but he wonders how the tomato plants felt chemicals in snail slime that never actually touched them.

“That’s the million-dollar question,” Orrock says. He hopes future research will make out the mechanisms that enable plants to sense these relatively distant cues.

A young couple viewing the paintings ahead of me chatted________between themselves. I watched them a moment and ________she was doing all the talking. I admired his patience for________her constant words. Annoyed by their noise, I moved on. I encountered them several times as I moved through the various rooms of art. ________I heard her constant talking, I moved away quickly.

I was standing at the counter of the museum gift store making a________when the couple approached the exit. Before they left,the man ________into his pocket and pulled out a white object. He turned it into a long cane (手杖) and then fought his way________into the coatroom to get his wife's jacket.

“He's a_________man,” the clerk at the counter said, “Most of us would________if we were blinded at such a young age. During his recovery, he made a________that his life wouldn't change. So, as before, he and his wife come in whenever there's a new art show.”

“But what does he get out of the art?” I asked, He can't see.”

“Can't see! You're wrong. He sees a lot. ________than you or I do,” the clerk said, “His wife________each painting so he can see it in his head.”

I learned something about patience, courage and love that day. I saw the________of a young wife describing paintings to a person without ________and the courage of a husband who would not allow blindness to change his life. And I saw the love________by two people as I watched this couple walk away arm in arm.

9 . If you think that running marathons will help you live a long and healthy life, new research may come as a shock. According to a recent scientific study, people who do a very strenuous workout are as likely to die as people who do no exercise at all.

Scientists in Denmark have been studying over 1,000 joggers (慢跑者) and non - joggers for 12 years. The death rates from the sample group indicate that people who jog at a proper pace two or three times a week for less than two and a half hours in total are least likely to die. The best speed to jog at was found to be about 5 miles per hour. The research suggests that people who jog more than three times a week or at higher speeds of over 7 mph die at the same rate as non - joggers. The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries(动脉). Over time, this can cause serious effects.

Peter Schnohr, a researcher in Copenhagen, said, “If your goal is to decrease risk of death and improve life expectancy(寿命), jogging a few times a week at a proper pace is a good strategy. Anything more is not just unnecessary, and it may be harmful.”

The implications (暗示) of this are that moderate forms of exercise such as tai chi, yoga and walking may be better for us than “iron man events, triathlons and long - distance running and cycling. According to Jacob Louis Marott, another researcher involved in the study, “You don't actually have to do that much to have a good impact on your health. And perhaps you shouldn’t actually do too much”.
