For many students today, distance learning has become the new normal. But distance learning means lots of screen time.
Research has shown that kids who spend a lot of time on screens are more likely to have various health problems and trouble with reading and language. Yet in the countries still suffering from the epidemic (流行病),screens are the only safe way for many young people to learn or socialize. It's difficult for kids and teens to navigate this dilemma.
In one 2019 study, Taren Sanders, a health scientist at Australian Catholic University in North Sydney, looked at how kids spent their screen time. His group then investigated whether the type o£ screen time made a difference in health and school achievements. The researchers sorted screen time into five types: passive (such as watching a movie) , interactive (such as . playing a video game), social, educational or something else.
Educational screen time was linked to doing better in school and had no bad health effects. More passive screen time was linked to worse outcomes in health and school achievements, Sanders' group found, compared with the other categories. But the impact was quite small. Major problems showed up mainly in kids spending more than eight hours a day on screens.
The most serious problem caused by too much screen time is that people usually sit still while they are in front ,o£ a screen. "If students are spending all day sitting on screens, when are they moving?” asks Guerrero, who studies patterns of diseases. “Extended time sitting and not moving around leads to obesity, diabetes, heart disease and other health issues. So an important question to ask yourself is not how much screen time are you getting, but how active are you?"
Sanders agrees. "Overall, I'm not too concerned about the additional screen time kids are having because of distance learning," he says. “The things you should worry about: The amount of exercise they get and the way they spend their free time. "

【推荐1】To control the nation’s growing problem with food wastage, the South Korean government has started a special initiative (倡议) ---“Pay as You Trash”. According to the initiative, the South Korean government has three methods in place to charge citizens for the food thrown away. One is through an RFID (Radio Frequency Identification) card — when users tap this card over a specially designed food waste bin, the lid will open. This waste is automatically weighed and recorded in the user’s account. The user needs to settle this bill every month.
The second billing method is through pre-paid garbage bags. These specially designed bags are priced based on the amount of space. For instance, in Seoul, a 10-liter garbage bag costs around 190 won (less than $1). There’s also a bar code management system in place, in which residents (居民) throw food waste directly into dustbins and pay for it by buying bar code stickers attached to the bin.
Even before the pay-by-weight system was introduced, South Koreans were still being charged for food waste — the cost was simply divided equally among the residents of each apartment block. The new system is not only fair, but is also designed to make consumers really feel the pinch of too much waste. The more food they throw out, the more they end up paying.
Thanks to the initiative, residents like Seoul housewife Ms. Kwan are now adopting creative methods to avoid food waste. She makes sure to pour all the liquid out of leftover food before throwing it away. While preparing vegetables, she tries to use as much as the eatable parts as possible in order to reduce waste.

【推荐1】Many Africans have Afros. And like anyone else,they send emojis to their friends-a zombie, or a mermaid or a genie. But which emoji can they use to represent themselves?
Right now, 2823 emojis are recognized by the Unicode Consortium(the UC), a non-profit organization that provides standards for text on the Internet and oversees emojis. Fifty-nine additional emojis are on the way, including a deaf person, interracial couples, and a mechanical arm.
Yet there are still no emojis of any person with an Afro, even though symbols exist for women and men with long and short hair, curly and straight hair, and blond, black and red hair.
Rhianna Jones, 28, is on a mission to change that. She and Kerrilyn Gibson,25,have started a Change organization calling for the addition of an Afro emoji designed by Ms. Gibson. They planned to submit the emoji to the UC over the weekend.
“What is amazing about our culture is that we have big hair, big energy, big stories and big voices,” Ms. Jones said. “Emojis are the best way we can summarize our personality in digital conversations. ”
The UC, which acts as the gatekeeper for emojis, includes executives from Apple, Google, Facebook and other tech companies. They meet quarterly and agree to add approved emojis once a year.
“The number of emojis is becoming quite large,” said Mr. Welch in an interview, a Unicode board member. “Every emoji adds to the amount of memory space on every phone. This isn't a big deal if you have the latest phone, but if you're in a developing country, with a small phone and not a lot of memory, it could be a big deal. This is why we don't open the floodgates.”
Many black women now see themselves in spaces they were not used to occupying and they are pushing to make those spaces bigger and more encompassing. “With the Afro emoji I want to create a space where we can bring that big-hair energy and celebrate our roots in digital spaces,” said Ms. Jones, who added that it was important that the emoji be “for us, by us”.

【推荐2】City traffic is a great problem. More cars are produced every year and the streets are getting more and more crowded. So during rush hours, when people are going to or from their work, traffic is brought to a standstill(停顿). It has been suggested that people should share their cars and give each other lifts. So each car would carry four or five people instead of only one.
When you park at a meter (仪表), you must put a coin in the slot (缝). This pays for a certain amount of time. The meter records this and it shows the time that you have paid for is finished. If the car is still there then, you have to pay a fine (罚款).
Traffic wardens (监察员) look after the meters. They walk around the streets and check that every meter shows that money has been paid for the car parked there. If a meter shows "TIME EXPIRED (到时)", the motorist who has left his car there is fined. Of course, the traffic warden cannot wait for the owner of the car to return. He carries a pile of paper, and on one of these he writes down all the details, such as the number of the car, where it is parked, how much the driver must pay and where he must send the money. He leaves this form on the car where the driver will be able to see it easily. When the driver comes back, he gets an unpleasant surprise, but it is his own mistake to park his car too long at a parking meter.

The survey by travel website hotels.com found London taxis, despite being the most expensive, beat rivals (对手) across the globe to head the list for the third consecutive (连续的) years, scoring a total of 59 percent in votes on several categories by travelers.
London taxi drivers were voted both friendliest and most knowledgeable. Drivers in the English capital must pass a rigorous examination called The Knowledge to earn their taxi license.
New York's yellow taxis came second in the list, scoring 27 percent which was up 10 percentage points from last year even though Manhattan's cab drivers tied (打成平局) with Parisian taxi drivers as the rudest.
Travelers said New York had the most convenient taxis.
Taxi drivers in Rome were voted the worst drivers in the world with almost one in ten travelers thinking the Italian capital had the world's worst taxi drivers when it came to the quality of driving.

The global survey scored city based taxis for their levels of cleanliness, value, quality of driving, knowledge of the area, friendliness, safety and convenience.
Rounding out the top five were Tokyo with a total score of 26 percent, Berlin with 17 percent, and Bangkok famed for its tuktuks scoring 14 percent.

What I find really fascinating is how our need for closure is affected by the situation we're in. Our need for closure rises when we have to act rather than just observe, and it matters much more when we're rushed, or bored, or tired. Any stress can make our discomfort with uncertainty increase, and a high need for closure negatively influences some of our most important decisions: who we decide to trust, whether we admit we're wrong and even how creative we are.
In hiring, for instance, a high need for closure leads people to put far too much weight on their first impression. It's called the Urgency Effect. In one experiment, psychologists tried to lower people's need for closure by telling them, right before participants are about to make various judgments of a job candidate, that they'll be responsible in some way for them, or that their judgments have serious consequences.
In making any big decision, it's not enough just to know that we should take our time. We all know that important decisions shouldn't be rushed. The problem is that we don't keep that advice in mind when it matters. So, one of the best solutions is to formalize the reminders. Before making important decisions, write down not just advantages and disadvantages but what the consequences could be. Also, think about how much pressure you're under. If your need for closure is particularly high that day, it's even more important to think twice.
1. How does "need for closure" probably come into being?
A.By accident. | B.By nature. |
C.By acquiring. | D.By imitating. |
A.brings about more stress |
B.leads to not so good decisions |
C.causes discomfort and uncertainty |
D.promotes one's creativity |
A.value their first impression |
B.be responsible for their boss |
C.be cautious about their judgments |
D.pay little attention to the consequences |
A.More helpful solutions to high need for closure. |
B.Some serious consequences of making decisions. |
C.Other approaches to making important decisions. |
D.Another strategy to escape the pressures of modern life. |
【推荐2】This is Ella Stevens who, at just 13 years old, is fighting for a chance to drive for the most famous team in Formula One-Ferrari(法拉利一级方程式赛车).
This fall Stevens faces a series of challenges, on and off track at the Paul Ricard circuit in France, with the ultimate prize a place on the famous Ferrari Driver Academy as its first female racer. “It’s a very good opportunity for me,” Ella, already a British karting champion, tells CNN. “We have to do a few fitness tests in the first phase so that they can see our driving.”
The Academy is, in fact, a breeding ground for future racing stars. Its current crop includes Mick Schumacher, the son of legendary Ferrari driver Michael, Enzo Fittipaldi, whose grandfather Emerson was a double F1 world champion, as well as Arthur Leclerc, the younger brother of Ferrari’s current FI racer Charles.
On the face of it, it’s no place for a 13-year-old girl from a small village in England—who already has a mountain to climb as a female in a sport still dominated by males. After all, a female has not raced in Fl for more than 40 years, and just six women have taken part in a grand prix(大奖赛)weekend.
But Stevens is being supported by a popular figure in the F1 community, Rob Smediey. He worked as a Ferrari engineer for more than a decade and is now teaching Stevens through his own Electroheads Talent Academy.
Smediey describes Ferrari’s search for a potential female racer as a “huge step”. “Having a major player in the sport, with such a rich history as Ferrari, leading on this has to be applauded”, he tells CNN. “It’s absolutely amazing that they want to do this and they’re taking positive action to increase the gender diversity within the sport.”

【推荐3】A visitor to The Silent Seed can open the door and then bang it with a loud noise. A few feet away, bending over his indoor flower bed, owner Jude Platteborze will never look up.
A light touch on his back, however, makes Platteborze straighten up with a wide smile, nodding. He makes them feel welcome without one word. He has to.
Platteborze, 31, who communicates through sign language, is deaf and hardly speaks. He usually uses a notebook to communicate with customers. He's just as happy, though, if the customers prefer not to talk, choosing instead to relax inside his store and explore the plants he's grown over years of self-taught planting techniques.
The Silent Seed opened a few months ago and was named after a poem his mother, Nancy Haverington, wrote about him when he was a baby and she realized he was deaf.
“Now this is my baby,“ Platteborze said of his store.
He takes care of all of the plants from young plants to their adult stage, and a large part of his business is selling the seeds (种子).He has traveled across eastern North America collecting different plants and seeds. From those, he grows seeds for the next generation of plants.
To give customers an idea of what their seed purchase(购买)will look like, Platteborze built an oversized flower box in the store. Different kinds of plants are there for visitors to examine and learn about, and to provide the kind of environment that will make people want to stay for a while.
“I want to offer a feeling of peace, and a place where they can just sit and think and share their interest in connecting to nature,“ Platteborze said. "And they can take part of that with them to their house. ”
Platteborze’s mother thinks that his love of plants is connected with his deafness. Deaf babies often have trouble with balance, and it took Platteborze three times the normal amount of time to learn to sit up. As a result, Haverington said, he spent quite a long time belly-side(腹部)down in the grass, nose-to-nose with plants and bugs.

【推荐1】One of the most traditional British holidays is the “seaside holiday”. Typically, families get on a train or into a car and travel to British seaside towns. They sunbathe on the beach, buy ice creams, eat fish and chips, build sandcastles and so on.
In the early 1970s, air travel became affordable for the average family in the UK, and more and more British people started travelling abroad for their summer holidays. After all, the British weather isn't very good, even in summer, so a lot leave the UK for a vacation. Particularly popular with families on a budget is the “package holiday", where the cost of flights and accommodation are offered at a discounted price by travel agents.
In the 1980s and 1990s, young people in the UK became more wealthy, or at least had more disposable income. As a result, young people started to go abroad in groups, to places such as Spain and Greece. Once at their destination, they socialized with other groups of young people and had one long party.
British holidaying habits have begun to change, however. Climate change means that the UK now has a warmer climate than before, so people don't always feel they need to go overseas to find good weather. Also, the world seems a less certain place as interconnected economics rise and fall, which means that the cost of foreign holidays is less predictable than it used to be. As a result, more and more Britons are choosing to spend their summer holidays in the UK.
In the UK, the domestic (国内的) tourism industry---when people go on holiday in their own country---is healthier than it has been in decades. There is now an increased appreciation among Britons for the diversity of the UK. It is not just the geography and the diversity of climate-based activities on offer. It is also the diversity of the cultures in the UK that is beginning to be of interest to domestic tourists
The UK has always been famous for its international explorers, but now it is starting to discover itself.
