1 . Humans have many unique behaviors among animals. For example, we have a formal language that permits communication about things that exist in the past, present, and future. Yet we share at least one emotion with many other species fear.

To really understand our fears we have to go further to study how animals long before humans came into being assessed (评估) and managed predation (捕食) risk in the wild. All animals, past and present, must assess life-threatening predation risks (风险) and make decisions to avoid or otherwise manage those risks. It is a proper balance: being too fearful is costly if fear means that you miss out on getting food, mates, or other important resources. However, being too brazen could end very poorly indeed. It is the context that influences all decisions. If they’re hungry, it’s wise to take more risks or they will go hungry. And, if they’re powerful and can steal food from others at will, perhaps it’s OK to be a bit more careful. Successful individuals are those that make right assessment, and because of this, leave more descendants.

Natural expressions of fear influence the structure of ecological communities, and the removal of predators changes entire ecosystems. To manage predation risks, animals modify(调整) their activity patterns, habitat selection,   and their diet. Fear of predators can also reduce an individual’s reproductive(繁殖)success. All of these fear-driven modifications can have a great influence on both the environment and the diversity of many species. Fear, as it turns out, is an essential part of healthy ecosystems and helps keep biodiversity.

Fear is a natural emotion, and that it’s impossible to completely avoid it. It is comforting to know that fear comes from a long line of ancestors, both human and nonhuman. It is a compass(指南针)that, when used I properly, guides us away from danger and toward opportunity.

4 . Family vlogging — the frequent recording and uploading of personal videos of the family, usually on video sharing website — has become big business nowadays, especially among parents of young children. The more viewers such videos can get, the more money the family can make. At first thought, it does seem like an easy way to make money. However, are we doing right by putting their lives up for public attention?

For one thing, as the children grow up, they increasingly become aware that what they do needs to be admirable enough for the public to enjoy — Being young children, they also would want to do whatever it takes to please others. They then feel the pressure to be perfect, and as that is something not always possible, they become anxious and stressed. Comments from viewers and the expectations of sponsors (赞助者) can also affect the parents’ reactions towards their children.

Another problem is the lack of privacy in the children’s lives. As the children reach adolescence, there is a greaser need for personal space. At 12 or 13, very few children would appreciate being filmed while eating or having a conversation with their friends. Teenhood is a time of significant change in an individual, both physically and emotionally, and is a time when parents need to protect their children and guide them, instead of exposing them to the eyes of the public.

Family vlogging can be irresistible, given how it allows parents to bring greater fun to their family lives. There is also the easy money and the fame to look forward to. Indeed, all would probably go well, but only as long as parents keep in mind that, if not managed well, making their children live their lives in the unforgiving eyes of the public could prove to be a big mistake.

5 . Directed by the AFM private company, National University of Science and Technology(NUST)MISIS engineers, together with the Karfidov Lab design group, have invented a machine named Salatomat that could serve meals to users in a very short time. The engineers say this machine cooks dishes from vegetables and cereals(谷物)in 30-60 seconds, so it can produce between 150 and 500 meals per day.

The cooking machine contains 16 basic ingredients-vegetables, cereals, potatoes, noodles-and 20 dressings and toppings. With this set, Salatomat can cook up to 1, 000 different dishes, with the user able to make a personal choice of products. These dishes are especially fit for those who live a healthy lifestyle or have some health problems.

“The machine has its own ‘brain’. It can remember users’ choices and medical history. And it knows what is in it and what it can produce with the help of the RFID chip,” said Aleksey Karfidov, head of the department of technological equipment engineering at NUST MISIS.

“The process begins with the preparation of products -putting ingredients into the robot, cutting vegetables, and controlling the temperature (cooling or heating, depending on the dish),” said Aleksey Karfidov. According to the developers, the robot is able to ensure the safety of food and quick preparation of well-balanced meals. The machine will also be completely non-contact-all cooking steps are carried out by itself.

All ingredients inside Salatomat are put into clean containers. Ingredients can be stored in the containers for eight hours at most, and if not used, they must be removed and cleaned.

6 . Born in an unknown village in Huarong county, Hunan province, Yi had few opportunities to play instruments when he was young.

At the age of 6, when most performers have already begun studying the piano at music academies, Yi learned the traditional stringed instrument the erhu from a group of people lodging at his home. It was not until much later that he first saw a piano when he visited his cousin’s house in Huarong.

“My family was too poor to buy a piano for me, so I often used to visit my cousin, even though it took about an hour to travel the 20 kilometers to his home over rocky roads just for the opportunity to sit at the keyboard,” Yi said.

Yi first arrived in Shenzhen 19 years ago and worked in factories, on construction sites and in kitchens. He had not played a piano for nearly 30 years.

The public pianos in Huaqiangbei offered him a fresh start. On a hot summer’s day, while   taking a break from work at a nearby construction site, Yi and his son passed one of the instruments. Encouraged by his son, Yi decided to give it a try.

He rubbed his hands nervously on his clothes, but the moment he placed his fingers on the keys, he felt more comfortable and his confidence returned. Although his masterly performance at the piano keyboard quickly made him an online sensation in China and overseas, Yi is not the only one to benefit from the pianos in Huaqiangbei.

Inspired by the British artist Luke Jerram, who has placed more than 2,000 street pianos in over 70 cities worldwide since 2008 with the words “Play Me, I’m Yours” printed on their sides, the public piano project in Huaqiangbei was launched by the local government in 2018.

Zhang Chen, deputy director of the Huaqiangbei subdistrict office, said: “Huaqiangbei is located in the commercial district in the center of Shenzhen. We have been trying to provide diverse facilities to bring high-quality public cultural services to the area. We are surprised that the public piano project has attracted so many people to play the instruments, and others to watch them perform.”

8 . Pleasanton Partnerships in Education Foundation (PPIE) was started in 1987 to raise money by organizing running events for local schools. Based in Pleasanton, California, a suburb of San Francisco, the non-profit organization recently hosted a family-focused fitness event for the community. “Our event helps to bring the community together,” said Mindy Louie, events and outreach manager for PPIE. “We have more than 3,000 participants, hard-working volunteers and viewers.”

This year’s fitness event took place on April 30 at the Alameda County Fairgrounds. It featured races of two miles, five kilometers and ten kilometers. A new Kids Challenge consisted of a quarter-mile run to encourage younger children to participate. When asked to describe the run, 11-year-old Jeremy Louie said, “Fun, exciting and enjoyable.” Jeremy added that he was happy to help support his school.

PPIE supports all 15 schools in the Pleasanton Unified School District, which include more than 14, 500 students and 800 teachers and staff. The nonprofit organization tries to fund programs affected by budget cuts, while encouraging fitness and athleticism. To date, the PPIE has raised over $1 million for the school district.

A local runners’ group called the BURN Youth Development (B. Y. D.) participated in the fundraising. The B.Y.D. has since grown to more than 100 youth members, 30 of whom ran in April’s PPIE event. Jerry Wu, the group’s founder and lead coach, explained that the B.Y.D. was born to keep kids running. “Watching them running strongly and happily makes me smile every time,” Jerry said.

Jerry encourages teamwork and teaches the students valuable running techniques. As a B.Y.D. member, Ollie Gu, an eighth grader, was one of the top finishers in the ten-kilometer run. He completed the race in 40 minutes and 46 seconds and won first place in the 12-to-15 year-old age group. “The race was extremely rewarding,” Ollie said. “I’m looking forward to it next year.”
