3 . When you hear the word "birthmark", you probably think of one of those black or brown spots that you have on your body. For me, it's different -I have them on my lips and inside my mouth. I'm used to being asked, "What are those black marks on your lips?" When I tell people they're birthmarks, they usually say, "That's strange." I used to consider them ugly. However, my mom calls them beauty marks

In pictures, I used to hide my birthmarks by pursing（噘起）my lips so I wouldn't have to deal with people's questions. As I was growing up, people wore me out with them. Some people would ask me the same questions even before knowing my name. In society I feel like we judge people by their looks before their personality.

My birthmarks are caused by a genetic condition from my mom's side of the family. My mom's mom has birthmarks on her lips, and my mom's uncle and my uncle have some on their bodies. Every year I plan to have a procedure to remove them. But when imagining the process, I always get nervous and give up.

My cousin faces a similar challenge. She has a huge birthmark that takes up her whole arm. She's never tried to hide it or change her appearance. Once, her grandmother told her that the birthmark looked extremely prominent and suggested that she should wear long sleeves more often. If my cousin had actually taken that suggestion, she wouldn't be such a person as she is.

Inspired by my cousin, I am finally accepting who I am and now I don't hesitate when someone asks me about them either. I say, "They`re beauty marks" and smile without pursing my lips.

5 . Research has shown that disrupting one's natural “morning lark” (早起鸟) or “night owl” (夜猫子) tendency can result in immoral behavior at work.

Who doesn't love a flexible work schedule? Being able to make your own hours, come in when you're ready and leave when you're done, step out to attend a child's presentation at school, have a midday appointment, or even squeeze in a quick workout or nap as a guaranteed pick-me-up — flexibility greatly improves one's quality of life.

The benefits don't stop there, however. Research has shown that having flexible work hours actually makes one a better person. How so? It's been found that disrupted sleep patterns —in the form of having to act outside of your normal inclination to be a morning “lark” or a night “owl” — can result in strange, unethical, and out-of-line behavior.

Science journalist Linda Geddes said, “If you don't get enough sleep, research suggests you are more likely to have unethical behavior, such as being mean, bullying your fellow employees or falsifying receipts. But it's not just owls: the larks tend to behave more unethically in the evening, and owls in the morning. So ideally, you want to introduce flexible working."

Employers would be wise to allow their employees to start whenever they feel ready — whether it's at the crack of dawn or at 11 a.m., and to allow breaks or pauses in the day as needed — because that would mean better productivity, performance, and behavior.

This shift is already happening, with the New York Times recently reporting that 27 percent of US employers now offer the flexibility to work outside normal business hours, up from 22 percent in 2014; and 68 percent allow telecommuting as needed (up from 54 percent in 2014). With the national unemployment rate at its lowest in 50 years, employers are having to become more competitive in what they offer workers, and flex-hours seem like a no-brainer, highly beneficial to all.

6 . In order to reduce the risk of suffering from COVID-19, people are supposed to say no to a handshake, give up high fives, refuse kisses on the cheek and absolutely avoid hugging. So people all over the world are changing their daily habits at work and at home to prevent it from spreading.

In France, handshaking is regarded as daily greeting habits. And kissing on the cheek is often seen even between people who have only just met. Philippe Lichtfus, a lifestyle expert notes that handshaking is a relatively recent development in human history that began in the Middle Ages. Now, he says simply looking into a person’s eyes can serve as a greeting.

The Brazilian health ministry has recommended that citizens should not share the metal straws traditionally used to consume the caffeine-rich drink chimarrão. And a kiss—even if it is not on the mouth—is totally advised against.

One of Spain’s most treasured traditions is also affected by the outbreak—the kissing of sculptures of Virgin Mary in the week leading up to Easter. During the holy week, the faithful believers queue up to kiss the hands or feet of sculptures of Mary and the saints, seeking their protection.

Germany’s interior minister (内政部长) Horst Seehofer rebuffed Chancellor（总理）Angela Merkel’s attempt to shake hands with him, smiling and keeping both his hands to himself. They both laughed and Merkel threw her hand up in the air before taking a seat.

In Iran, a video has gone viral (走红) showing three friends meeting, hands in their pockets, two of whom are wearing masks, tapping their feet against each other as a greeting. A similar video in Lebanon shows singer Ragheb Alama and comedian Michel Abou Sleiman tapping their feet against each other while making kissing noises with their mouths.

The UAE (阿拉伯联合酋长国) is advising citizens to stop the traditional “nose to nose” greeting. The UAE also said that people shouldn’t shake hands anymore or kiss. Greet each other “by waving only”.

7 . There is more that comes with older age than greying hair and wrinkled skin When humans reach their later years, they favour more established friends and their social circle is reduced.

Now, for what appears to be the first time, scientists have seen the same behaviour in another species. Twenty years of observations of chimpanzees (猩猩) reveal that older males choose to hang out with their long-term friends at the expense of other relationships.

The researchers studied 78, 000 hours of observations made between 1996 and 2016 that followed the social interactions of 21 male chimpanzees between the ages of 15 and 58 years old. They classified the chimps’ relationships depending on the amount of time they sat with others and groomed (梳毛) them. They then rated the various pairings as mutual (相互的) friendships, where both chimps seemed to enjoy the relationship; one-sided friendships, where one chimp was more keen to be friends than the other; and non-friendships, where neither chimp showed interest in the other.

When the scientists looked at the patterns of friendships, they found that the older chimps had more mutual friendships and fewer one-sided friendships than younger chimps. Another feature seen in older humans was also spotted in the chimps. As the males got older, their levels of aggression (挑衅) tailed off, meaning they started fewer fights and tended to intimidate others in their group less often.

The observations have left the researchers puzzled. According to an idea in psychology known as socioemotional selectivity theory, or SST, older humans prefer more positive relationships because they are aware time is running out. But many animal experts argue that chimpanzees lack the human sense of mortality (死亡), suggesting something else is driving the behaviour.

Robin Dunbar, a professor of evolutionary psychology at the University of Oxford, said in humans, the decline in social circles with age is due to declining social motivation to get out and meet people combined by lack of opportunity. In chimpanzees, as older males compete less for mates, they may focus on close, reciprocal (互惠的) relationships with trusted partners, she said.

8 . “A CAREER BOOK about Asians? Aren’t they doing fine…?” So begins Breaking the Bamboo Ceiling, a very large scholarly book by Jane Hyun published in 2005. Because Asian-Americans had higher incomes and education levels and committed fewer crimes than their average countrymen, they were seen as a model minority. Despite this, they rarely rose to the top of companies. A mix of individual, cultural and organizational barriers — the “bamboo ceiling” of the book’s title — seemed to prohibit them from rising.

Fifteen years later Asians are still under-represented. In the technology sectors, Asians make up over 30% of the workers but less than 15% of bosses. In 2017 Asians made up roughly 6% of the country’s population but only 3% of the bosses of S&P 500 (标准普尔 500 指数) firms.

Some prominent Asians run big companies. Arvind Krishna is IBM’s new boss. Satya Nadella runs Microsoft and Sundar Pichai leads Alphabet. But few other Asians have joined their ranks — and, revealingly, these stars all have Indian roots. There are fewer South Asians in America than East Asians, but they still made up 13 of all 16 Asian S&P 500 CEOs.

Why are there so few Asians among America’s business elite? And if a bamboo ceiling is to blame, why do South Asians break through more easily? These questions are the focus of a study by Jackson Lu of MIT Sloan School of Management and colleagues, who surveyed hundreds of senior executives and business-school students. They found that while discrimination exists, it is not destiny. South Asians endure greater racism than East Asians but still outperform even whites (if success is weighed against share of population). Their research also rules out lack of ambition: a greater share of Asians than whites endeavor for high-status jobs.

That leaves culture. The researchers conclude that South Asians tend to be more determined and confident than East Asians in how they communicate at work, which fits Western concepts of how a leader should behave. The same tendency for confident remarks featured in “The Argumentative Indian”, a book by Amartya Sen, a Nobel-prize winning economist. The researchers owe East Asians’ silence to Confucian values of modesty and respect for social ranking. Sometimes bravery and bombast are needed to break bamboo.

9 . When I was young, I dreamed of becoming many things. Sometimes, I wished I were an astronaut going up into space, finding new planets and jumping around in a cool space suit. Other times, I imagined being a cowboy in the Wild West, wearing stylish cowboy boots. On other occasions, I pretended to be a famous footballer, using my skills to score lots of goals for my team.

Looking back, I realized that the imagination is a wonderful thing. I was able to create entire environments and scenarios in my head, using nothing more than my brain, and to be able to adapt things in my everyday surroundings to fit the specific story of the day. Growing up with siblings（兄弟姐妹）also helped, as it meant that even bigger stories, as sometimes I could be the hero while on other occasions, I would be the bad guy.

One of my all-time favorite memories as a kid was playing in my back garden. I played the role of Indiana Jones, with my younger sister as my assistant and my brother as a bad person. We used everything in our gardens, from the path to the fence, as part of the storyline to create obstacles that needed to be overcome, and we would keep the story going for hours!

My personal favorite was Indiana Jones and the Stolen Easter Eggs, where my brother hid small chocolate eggs around the garden and my sister and I had to find them by answering questions or solving a puzzle. It was difficult, but eventually we found all the eggs and shared them together.

Since then, I have seen many great things and met many amazing people. The elements of fun and variety of my imagination are what I try to bring into every part of my life, and I enjoy sharing with and hearing about other people's stories, too.

10 . 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.
