1 . In a large survey of people's first memories, nearly 40% of participants reported a first memory that is likely to be fictional, according to findings published in Psychological Science, a journal of the Association for Psychological Science.
Current research indicates that people's earliest memories date from around 3 to 3. 5 years of age. However, the study from researchers at City, University of London, the University of Bradford, and Nottingham Trent University found that 38.6% of 6, 641 participants claimed to have memories from age 2 or younger, with 893 people claiming memories from age 1 or younger. This was particularly prevalent among middle-aged and older adults.
As many of these memories dated before the age of 2 and younger, the authors suggest that these fictional memories are based on remembered fragments(碎片) of early experience—such as a pram(婴儿车)，family relationships and feeling sad—and some facts or knowledge about their own infancy or childhood which may have been derived from photographs or family conversations.
“Further details may be unconsciously inferred or added, e. g. that one was wearing nappy when standing in the cot(幼儿床)," added Shazia Akhatr, first author on the study and Senior Research Associate at the University of Bradford.
“When we looked through the responses from participants we found that a lot of these first 'memories' were frequently related to infancy, and a typical example would be a memory based around a pram," explained Martin Conway, Director at the Centre for Memory and Law at City, University of London and coauthor of the paper.
“For this person, this type of memory could have resulted from someone saying something like 'mother and a large green pram'. The person then imagines what it would have looked like. Over time these fragments then become a memory and often the person will start to add things in such as a string of toys along the top," he added.
"Crucially, the person remembering them doesn't know this is fictional," Conway noted. "In fact when people are told that their memories are false they often don't believe it. This partly due to the fact that the systems that allow us to remember things are very complex, and it's not until we're 5 or 6 that we form adult-like memories due to the way that the brain develops and due to our maturing understanding of the world.

2 . Artificial Intelligence (AI) advice is as influential as human’s, but positive crowd views still overpower.
In a study, researchers found that machines that make recommendations—or AI experts—were as influential as human experts when the AI experts recommended which photo users should add to their online business profiles. However, both AI and human experts failed to budge them if their feedback was negative and went against popular views among other users, said S. Shyam Sundar, a professor of Media Effects.
Because people are increasingly using social media to look for feedback, studies suggest that expert opinions and the bandwagon（从众效应）effect may be important factors in influencing decisions, according to Jinping Wang, a doctoral candidate in mass communication and first author of the study. “Nowadays, we often turn to online platforms for opinions from other people—like our peers and experts—before making a decision,” said Wang. AI experts are often less expensive than human experts and they can also work 24 hours a day, which, Wang suggests, might make them appealing to online business.
The researchers also found that the AI’s group status—in this case, national origin was pointed out—did not seem to affect a person’s acceptance of its recommendation. Among human experts, however, an expert from a similar national origin who offered a negative opinion of a photograph tended to be more influential than a human expert from an unknown country who offered a similar negative rating of a photograph.
While findings that suggest group status may not affect whether a person values the view of AI experts sound like good news, Sundar suggests that the same cultural prejudice might still be at work in AI experts for they could be hidden in the programming and training data.
“It can be both good—and bad—because it all depends on what you feed the AI,” said Sundar. “While it is good to believe in AI’s ability to transcend（超越）cultural prejudice, we have to keep in mind that if you train the AI on pictures from one culture, they could give misleading recommendations on pictures meant for use in other cultural contexts.”

A young man whose good looks and innocent smile have turned him into an internet celebrity has brought a surge in interest in his hometown among tourists.
Ctrip, an online travel agency, said that after a video of Tamdrin, a 20-year-old ethnic Tibetan man from Litang county in Sichuan province's Garze Tibetan autonomous prefecture, became popular online recently, the number of searches for Litang increased quickly.
Hua Chunying, a spokeswoman for the Foreign Ministry, featured Tamdrin in three tweets in a row on her Twitter account on Monday. “The channel of Sicfiuan TV has a new ‘anchor’, Tamdrin, who broadcasts news in his native Tibetan language as a guest,” she wrote. “Tamdrin recently became a social media star after a photo of his bright, sunny and innocent smile had become popular.” She also posted a short clip of Tamdrin riding a horse and introducing himself in subtitling: “They call me ‘prince on a horse’. The happiest thing for me is to race horses with my brothers. Tm really good at horse racing and often rank first in our village. ”
Tamdrin has now been hired by Litang Culture Tourism and Sport Investment Development Co. to promote tourism for the county. Du Dongdong, the company’s general manager, told China Central Television he hoped the young man could grow and develop alongside local tourism, which has just started to take off.
Tamdrin said in a CCTV interview that he didn’t know why he had become so well-known, but he was happy that so many people knew of him, and he was excited to help people learn more about his hometown. He added that he planned to learn many things and hoped he would do well in his work for the company. "At the same time, I still want to race horses and continue to be a champion,” he said in Tibetan.

4 . Do you like the woolly mammoths from the movie Ice Age? Too bad they're extinct? Thanks to recent developments in biotechnology, the stuff of science fiction may soon become a reality through an attractive process called "de-extinction", which aims to bring the extinct species back. The resurrected species are functionally equal to the original extinct species, but they are not exact copies.
There are three primary techniques of de-extinction. One of them is that scientists deliberately select existing species with similar characters to the extinct species to produce later generation. This is a natural method. Another is cloning. A cloned animal is created by obtaining the DNA of the extinct animal. The later generation will be an identical copy of the extinct species. This is only applied to animals that are either endangered or have recently gone extinct, as it requires well-preserved eggs. The third is the newest technique, genetic engineering. It uses gene-editing tools to place selected genes from extinct animals in place of those present in its closest living relative.
If we refer to Jurassic Park , resurrecting extinct animals is a terrible idea. Thankfully, we don't have to worry about dinosaurs running wildly, as their DNA has disintegrated over the 65 million years since their extinction. DNA can survive for several million years at best under certain rare conditions, but does that mean we should do that?
De-extinction is more for ecology than for tourism. Ecologist Ben Novak said, “All animals perform critical roles in their ecosystem. Woolly mammoths, for example, were excellent gardeners. Their disappearance was followed by a loss in diversity and the Arctic grassland became a cold, ice field. If a resurrected animal is always going to be a zoo animal then it shouldn't be brought back.”

5 . Papa, as a son of a dirt-poor farmer, left school early and went to work in a factory,for education was for the rich then.So, the world became his school.With great interest, he read everything he could lay his hands on, listened to the town elders and learned about the world beyond his tiny hometown."There's so much to learn," he'd say.“Though we're born stupid, only the stupid remain that way.”He was determined that none of his children would be denied(拒绝)an education.
Thus, Papa insisted that we learn at least one new thing each day.And dinner time seemed perfect for sharing what we had learned.We would talk about the news of the day;no matter how insignificant, it was never taken lightly.Papa would listen carefully and was ready with some comment,always to the point.
Then came the moment-the time to share the day's new learning.
Papa, at the head of the table, would push back his chair and pour a glass of red wine,ready to listen.
Felice, “he'd say,”tell me what you learned today.“learned that the population of Nepal is...”
Silence.
Papa was thinking about what was said, as if the salvation(拯救)of the world would depend upon it.“The population of Nepal.Hmm.Well...”he'd say.“Get the map; let's see where Nepal is.” And the whole family went on a search for Nepal.
This same experience was repeated until each family member had a turn.Dinner ended only after we had a clear understanding of at least half a dozen such facts.
As children, we thought very.little about these educational wonders.Our family,however,was growing together,sharing experiences and participating in one another’s education And by looking at us,listening to us, respecting our input, affirming(肯定)our value; giving us a sense of dignity, Papa -was unquestionably our most influential teacher.
Later during my training as a future teacher studied with some of the most famous educators.They were imparting(传授)what Papa had known all along-the value of continual learning.His technique has served me well all my life.Not a single day has been wasted, though I can never tell when knowing the population,of Nepal might prove useful.

6 . Social distancing is not a new concept in the natural world, where infectious diseases are commonplace. Through specialized senses animals can detect certain diseases and change their behavior to avoid getting ill.
In 1966, while studying chimps (猩猩) in a Tanzanian national park, zoologist Jane Goodall observed a chimp named McGregor who had caught a highly infectious virus. His fellow chimps attacked him and threw him out of the troop. In one instance, McGregor approached chimps in a tree. He reached out a hand in greeting, but the others moved away without a backward glance.
“For a full two minutes, old McGregor sat motionless, staring after them,” Goodall notes in her 1971 book In the Shadow of Man. “It’s really not that different to how some societies react today to such a tragedy.”
Not all animals are so aggressive toward their ailing neighbors. Sometimes it’s as simple as avoiding those who may infect you.
When Kiesecker, a lead scientist in America, studied American bullfrog in the late 1990s, he found that bullfrogs could not only detect a deadly smell of infection in other bullfrogs, but healthy members actively avoided those that were sick. Bullfrogs rely on chemicals signals to determine who is sick or not.
Caribbean lobsters also shun diseased members of their community, well before they become infectious. It takes about eight weeks for lobsters infected with the deadly virus Panulirus argus mininuceovirus to become dangerous to others. Normally social animals, lobsters begin keeping away from the diseased as early as four weeks after infection – once the lobsters can smell certain chemicals released by sick individuals.
Overall, it’s important to note that, unlike us, animals don’t realize if they stay home, they might actually reduce the infection rate,” Kiesecker explains. “As humans, we have that ability. It’s a big difference.”

7 . As my husband and I drove down a country road, we passed a fire station with a sign that read, "Are you ready for the next storm?” Our area had just been in the path of Hurricane Irma, causing downed trees and outages. We were stuck in the dark and cut off from the outside world.
We have had our share of storms in the past--a snowstorm and other heavy snows that knocked down trees, sometimes up to a week at a time. Those days in a cold house weren't fun, but we learned so much from those early storms, things that made later storms easier to bear.
Now we have stored up flashlights, lanterns and candles. We bought a battery-operated radio to keep up with the news. We stocked up on batteries so that we'd have plenty for extended power failures. We make sure our grill（烤架） is ready and its tank is full, and we purchase food that can be easily prepared and then cooked or heated on the grill. And we don't forget to buy emergency chocolate! We have book lights to read in the dark. We keep our car gas tanks full and have emergency cash on hand.
We're ready for the next storm, but we wouldn't have learned to do all those things if we hadn't encountered a storm in the past. The same is true spiritually. Those little storms in our lives are never fun, but they prepare us for the big storms--the big trials--that will come our way, They can teach us some valuable lessons.
Are you ready for the next storm? Now is the time to get ready. . . not when the storm arrives.

8 . A team of conservationists (环境保护主义者)captured 14 Loa water frogs earlier this month in northern Chile, a wildlife group reported.
The International Union for Conservation of Nature (IUCN) lists the Loa water frog as "critically endangered''. The not-for-profit Global Wildlife Conservation group said the 14 frogs were in poor condition when they were discovered in late June. The animals were small and struggling because of a lack of food and water.
The Loa water frogs are known to live only in a single body of water near Calama, in Chile. The city sits in the middle of the Atacama Desert, where water is in great demand.
There was little water in the area where the frogs were found, the conservation group reported. The frogs' environment had mostly dried up because water is being taken away and used for human activities, the group said. The activities include mining, agriculture and land development. "All of the frogs had been pushed into a tiny pool of muddy water, the organization said. "The team collected the last 14 individuals and brought them to the National Zoo of Chile to start a conservation breeding program. "
Zoo specialists are closely watching the small creatures and trying to give them everything they need to survive and be healthy. Conservation groups have called on Chile's government to take steps to halt any illegal water usage that threatens the frogs' natural environment. They would also like to see creation of a government-supported shelter to protect the animals.
Jon Paul Rodriguez heads the IUCN's Species Survival Commission. He suggested that an emergency plan be developed to prepare the Calama area for the frogs' return.
"We need to work very hard to restore their environment because it's pointless to breed them if they don't have a home to go back to in the wild," Rodriguez said.

9 . The world’s first fully electric plane has flown successfully for almost 15 minutes. The world’s first fully electric commercial aircraft took its first test flight on Tuesday, taking off from the Canadian city of Vancouver and offering hope that airlines may one day end their polluting emissions.
“This proves that commercial airmail in all-electric form can work,” said Roei Ganzarski, CEO of Seattle-based engineering firm MagniX. The company designed the plane’s motor and worked in partnership with Harbour Air, which carries half a million passengers a year between Vancouver, Whistler ski resort and nearby islands and coastal communities. Ganzarski said the technology would mean significant cost savings for airlines—not to mention zero emissions. “This signifies the start of the electric airmail age,” he told reporters.
Civil airmail is one of the fastest growing sources of carbon emissions as people increasingly take to the skies and new technologies have been slow to make remarkable progress. At 285 grammes of CO2 emitted per kilometre (mile) travelled by each passenger, airline industry emissions far exceed those from all other transport, according to the European Environment Agency.
The e-plane—a 62-year-old, six-passenger DHC –2 de Havilland Beaver seaplane improved on with an electric motor—was piloted by Greg McDougall, founder and CEO of Harbour Air. “For me that flight was just like flying a Beaver, but it was a Beaver on electric steroids (电动兴奋剂). I actually had to turn off the power button,” he said. McDougall took the plane in a short circle along the Fraser River near Vancouver International Airport in front of around 100 onlookers soon after sunrise.
1. What can we know from the first fully electric plane’s success?| A．The flying time of e-plane is 15 minutes at most. |
| B．The fully electric commercial airmail has functioned. |
| C．Airlines may realize the goal of zero emissions. |
| D．The fully electric plane never does damage to the environment. |
| A．Means. | B．Proves. | C．Changes. | D．Follows. |
| A．The pollution caused by passengers. | B．The backward airmail technology. |
| C．The current situation of civil airmail. | D．The growing sources of carbon emissions. |

10 . How can we possibly cope with the large amount of information about virus spread,stock market nosedives,canceled plans and uncertainty about the future?Some people are buried in the fear,anxiety and sadness,checking news sites and social media constantly.Others try to suppress it all and ignore the outside world(I'm guessing that Instagram has never seen so much traffic).
There's a third option,though.Rather than fully involving in the negative or ignoring it, we can do our best to experience joy alongside everything else that is sad in the world.In fact, research that I and others have conducted suggests that allowing the two different emotions to coexist may actually benefit us in the long run.
Dr.Jeff Larsen and his colleagues coined something known as the"coactivation model of mixed emotions",and the basic idea is that we may be able to deal with,and learn from negative emotions like sadness if we experience them concurrently with positive emotions like joy at the same time.Here,positive emotions provide a psychological buffer(缓冲），making it easier for people to deal with the things they don't want to face.
The comedian Mitch Hedberg proposed an analogy that captures this essence quite well, noting that“it would be cool if you could eat a carrot with an onion ring and they would travel down to your stomach.Then they would get there,and the carrot would say,'It's cool,he's with me .’ Applied to our emotional lives,we could do a better job in digesting,processing gaining insight into the negative events in our lives if we could do so alongside the positive.
Several years ago,my partner Jon Adler and I set out to test this exact idea.Specifically, we looked at sample of adult volunteers who signed up or weekly mental health therapy sessions.Between each week,they reported the feelings they were having and also took a few questionnaires that were meant to assess their overall health.This design allowed us to examine how different emotional experiences would impact mental health in a longitudinal fashion,over the course of 12 weeks.
