This past January, Lucy Liu reached a milestone in her art career(事业). The world-class actor, director and visual artist presented her work titled "Unhomed Belongings" in a museum exhibition for the first time.
Liu has been making art since she was a teenager and still sticks to a consistent studio practice alongside her work as an actress and director. She got her start while growing up in Queens in the 1980s, wandering New York City streets with a camera in hand. Her first artworks were photographs. After taking a class at New York Studio School, she turned to painting. "I felt like I wasn't able to express fully what I wanted with the photograph," Liu explained.
With painting, she discovered that her work didn’t have to be realistic or exacting, or meet certain expectations. "Everyone has a different format for how they want to show what they are thinking about, or what they are seeing to the audience," he said. "I just had to let go of the audience and just started thinking about what I wanted to see." Over time, Liu has also experimented with sculpture, silkscreen and textiles. She looks up to artists like Willem de Kooning, Agnes Martin and Robert Frank, but she feels that her lack of a traditional art-school background has helped her to naturally grow and experiment as an artist, which helps a lot to set her apart from other artists.
Much of Liu's work traces(追溯)back to her childhood. "Because we were an immigrant family and I am first-generation, I always had this imbalance of belonging," she explained. "I think at first it was the language barrier, not speaking English, but then it started becoming about how I look." Art, she explained, became a way to reflect on her younger self. "I think that art helps evaluate some of the psychology of yourself as a child, and to throw light upon some things you may never have understood," she said.

【推荐1】In my second year of high school, I took my first computer science course, which helped me realize I was interested in software. The idea of creating something from just lines of codes and logic was very fascinating. And I didn't put as much time into music as I used to, thinking practicing the piano was just a waste of time.
A year later, when I got back on the piano, I quickly noticed my musical ear was not as strong as it was before. I could no longer hear the difference between a perfect 4th and a perfect 5th or between a D and D flat. Then I had a firm decision to get my skills to where it used to be. After weeks of practicing, I didn't see much progress. I was extremely discouraged and felt that I would have to accept that I no longer will be able to play as well as I used to.
While watching hundreds of tutorials online on how to code in Swift I came up with an idea. What if I used the knowledge I gained from these tutorials to develop an app that would help train my musical ear. After hours of coding, I developed an app that would play a different series of notes, then the user would have to type in the corresponding notes to what they heard. When I was on the subway or had some extra time I could easily open up the app on my phone and use it to help my musical ear. In about 2 months, I regained the skills I lost.
This experience helped me see something that I never noticed before. Programming gives me a platform to express my ideas; in a similar way, playing the piano gives me a way to express my feelings. When playing through a song for the first time I hear many errors. Similarly, when I run my program for the first time there are usually many mistakes. In both of these cases, it takes patience to go through each measure or line to hear or find the error. I realized when I’m playing the piano I am also practicing my programming skills and vice versa.

【推荐2】On his first day as an airport official tasked with COVID-19 prevention and control, Wu Ge was assigned to prepare a waiting area at Pu dong International Airport specifically for transit passengers.
The task would have been challenging for most people, but Wu took it and quickly distributed tasks to his colleagues. Together, they cleaned and disinfected the area, set zones for checking people's temperatures and filling out forms. It wasn't until the first passenger stepped into the waiting area that Wu finally took a break from his work.
Born in southwestern China's Chongqing, the 46-year-old began working at Pu dong International Airport in 2007 and is currently an official leading more than 300 staff members of the Shanghai airport authority's security check and protection department.
As the nation's busiest airport for overseas travelers. Shanghai Pu dong International Airport is currently battling the COVID-19 with closed-loop management. During this critical period, Wu and his colleagues have been assigned to a special task force in charge of separating overseas travelers into various categories, sending passengers to quarantine spots and safeguarding passengers during transfers.
"This job requires care, responsibility and hard work. Our teammates have sweat all over their bodies as they have to wear N95 face-masks and protective suits all the time. Each of us walks at least 30,000 steps every day. Sometimes we even hit 60,000 steps," he says.
Wu's work as the group leader is nonstop. Breakfast is sometimes the only meal he has in a day. Wu says he tries his best to reduce waiting time for passengers. He has also arranged for hot water and biscuits to be made available for passengers around the clock.

【推荐3】It can be hard to convince homeowners to use less water on their lawns (草坪), particularly during a hot and dry summer. But tell them it’s a competition for the ugliest lawn, and suddenly they may be more willing to give up using the sprinkler(洒水器).
This clever strategy was employed by the government of Gotland, Sweden’s largest island located in the Baltic Sea. Gotland sees its population double during the summer months as tourists arrive. This puts pressure on the island’s already-limited water supply, which is projected to decrease by 13% between 2021 and 2050, as demand is expected to rise by 40% by 2045.
The campaign, called “Gotland’s Ugliest Lawn”, urged homeowners to compete for the saddest, deadest and brownest yard. They were asked to avoid watering for an entire season, then post a photo of the lawn using a label that linked it to the campaign.
Mimmi Gibson, the acting marketing and brand manager at Region Gotland, said that “the ugliest lawn contest would remind the islanders not to waste water, and to talk about ways they can adapt their gardens to suit the existing conditions and the climate crisis”.
The winner for this year was announced in mid-August, and it’s Marcus Norstrom, who did not water his lawn once throughout the entire summer. His photo shows a large brown space with some sparse yellow grasses sticking out——the kind of yard in which you would not want to walk barefoot (赤脚地)for risk of hurting your feet. The government must be feeling pleased ; its strategy has worked.
It’s an interesting strategy which attempts to normalize and even celebrate dead grass. It is reasonable to assume that the more people see it around their communities, the more acceptable it will become. They may also grow curious when they realize there are other ways to create and maintain an attractive-looking yard, even without irrigation(灌溉).

【推荐1】Bradley McConachie, a 33-year-old Australian is actually a student in international relations completing his PhD through Griffith University. He came to Beijing for a cooperative research at Beijing University two years ago. Such an academic life was colorful with a chance offered by the cultural exchanges project, “I'm in China".
Bradley was lucky to win the most "likes" for his photo story about his life in China and became one of 20 winners to visit locations by the project this summer. All the winners’ experiences were filmed to produce a reality show, My Chinese Working Day, which will be broadcast by mid-September.
Bradley was chosen to work as a recreational manager for a Chinese wedding. The film crew took them to many “amazing sites" and the staff at the resort taught them a lot about how to incorporate modern Chinese features while still keeping traditional customs.
“I would have to say two things stick out as the most memorable： the helicopter ride and talking with the staff at the hotel about how they organize weddings here in China," he said. That was Bradley's first time to be in a helicopter, and he was too absorbed with the “stunning" view of the coastline.
“I think it is so important to show other Australians the different landscapes China has to offer. I think so many Australians, when they think about China, imagine the historical sites of Beijing and the exciting things to see in Shanghai but have no idea about other beautiful places, like Sanya or the many other places people have been taken to in this TV series. It was nice to experience these little touches. I was happy to be a part of that experience!” Bradley said.

【推荐2】Barditch High School decided to have an All-School Reunion. Over 450 people came to the event. There were tours of the old school building and a picnic at Confederate Park. Several former teachers were on hands to tell stories about the old days. Ms. Mabel Yates, the English teacher for fifty years, was wheeled to the park.
Some eyes rolled and there were a few low groans (嘟囔声) when Ms.Yates was about to speak. Many started looking at their watches and coming up with excuses to be anywhere instead of preparing to listen to a lecture from an old woman who had few kind words for her students and made them work harder than all the other teachers combined.
Then Ms. Yates started to speak: “I can’t tell you how pleased I am to be here. I haven’t seen many of you since your graduation, but I have followed your careers and enjoyed your victories as well as crying for your tragedies. I have a large collection of newspaper photographs of my students. Although I haven’t appeared in person, I have attended your college graduations, weddings and even the birth of your children, in my imagination.”
Ms. Yates paused and started crying a bit. Then she continued: “It was my belief that if I pushed you as hard as I could, some of you would succeed to please me and others would succeed to annoy me. Regardless of our motives, I can see that you have all been successful in your chosen path.”
“There is no greater comfort for an educator than to see the end result of his or her years of work. You have all been a great source of pleasure and pride for me and I want you to know I love you all from the bottom of my heart.”
There was a silence over the crowd for a few seconds and then someone started clapping. The clapping turned into cheering, then into a deafening roar (呼喊). Lawyers, truck drivers, bankers and models were rubbing their eyes or crying openly with no shame all because of the words from a long forgotten English teacher from their hometown.

【推荐1】You wait 50 years for a flying car,and then three come along at once.First up is Vahana:an airbus project to develop batterypowered,single- seater aircraft,designed to follow predetermined routes,only changing directions to avoid accidents.Propellers(螺旋桨)on the wings will let it take off and land without a runway.
Second,Dubai recently announced plans to use self-controlled air taxis as a way to beat the terrible traffic jams.The Volocopter is an electric multi-copter with 18 propellers and a fully self-controlled system.It’s essentially a self-controlled aircraft with two seats and up to 30 minutes of flying time.
But,if you want something more like the flying cars of 1950s science fiction,try Urban Aeronautics’ Fancraft.The Israel-based company wants to realize the dream of”an aircraft that looks like the classic vision of a flying car:doesn’t have a wing,doesn’t have a propeller that can be seen,and can fly exactly from point to point,”says Janina Frankel-Yoeli,Urban Aeronautics’ vice president of marketing.Earlier flying cars needed runways to take off and land which was,as Frankel-Yoeli says,”not much better than owning a car and an aircraft.”To go from point to point requires vertical take-off and landing,but for many years that could only be done by helicopters or larger aircraft.Urban Aeronautics’ solution is to use light but powerful engines,lightweight materials,and a self-controlled system.Their fan design-propellers housed in some special tubes-is powerful but unstable,so the Fancraft would be challenging for a human to fly without any help.Instead,computer-aided control technology takes over the tiny,quick changes required to keep the car stable at speeds of 160km/h or more.
But don’t be glad too early yet.The main problem to a sky full of flying cars is rules.Not only will every aircraft need to pass strict safety tests,but a new system of air traffic control will be needed to deal with 3-D traffic jams above people who are not aware of what is happening in the sky.NASA is already working on that.Tests have shown that multiple unmanned(无人的) flying cars can communicate with each other to avoid accidents.In the meantime,flying cars will mainly be reserved for emergency services and a few VIPs.

【推荐2】Have you ever imagined travelling to the deep undersea and staying there for some days or even some weeks? Many people may think it impossible. But those who have gone to live in Saturation City—a new undersea city, will tell you it's quite possible. There will be no suffering. In fact it is so comfortable that it has been described as“a silk adventure”.
It's not easy for companies to design undersea cities in the past. The sea bottom is too deep, which has caused problems with communicating between underwater and the sea surface. This difficulty has been resolved by the one-person or family shuttle-submarines(潜水艇) which will always be ready to take people to the surface. Every one will be transported quickly and safely to their destination.
The city designers have special concern about the security of all the families. Careful entry procedures(进入程序) are required whenever people enter or leave Saturation City. There are advanced computers monitoring(监控)all the houses and streets. No object can be removed freely by strangers. Only when the robot cleaner touches the objects can they be moved. This new and revolutionary piece of computer equipment comes free with every house. It will certainly add to your quality of life in Saturation City.
There will be no household worries in Saturation City. Each house comes with its own robot for family use only. Your details will be programmed into its computer so that it will only answer your family’s commands. So a spotless house is yours as soon as you move in.
We hope that the above information is enough for you to decide to experience the journey deep undersea.

【推荐3】May 14 marks the beginning of National Smile Month in the UK. The campaign is organized by the Oral Health Foundation to promote(普及) dental(牙齿的) health. The Foundation hopes that a month of smiling across the nation will make people think about the importance of brushing their teeth regularly, cutting down on sugary foods, and making regular appointments with the dentist.
The British, in fact, have a reputation for bad teeth. The Internet's Urban Dictionary has an entry(条目)for “ British Smile”, defining it as “Any smile with bad teeth”. On the other side of the Atlantic, however, the “Hollywood Smile” gets its name because American movie stars are so proud to show off their sparkling beautiful teeth.
But what about smiling in the UK in general? Do the British smile a lot, or do they look sad all the time? It's said that the British practice the “stiff upper lip”, meaning that they don't often show their emotions; they neither smile nor cry. But this is false: A British person likes to smile as much as anyone else.
As far as smiling in Britain is concerned just like everywhere else, it all depends on the situation. For example, you wouldn't expect anyone to smile at a funeral(葬礼). But if you were at a party of any kind, you'd find everyone smiling from ear to ear. However, smiling is sometimes not allowed under some circumstances(情形). For instance, since 2005 Britain hasn’t allowed smiling in passport photographs. At other times, for example at work and school, you simply smile when it's natural to smile.
So the British are no more and no less likely to smile than anyone else. But smiling is good for you, no doubt about it, even if you do have a few bad teeth. And smiling is good for those around you too. This alone makes National Smile Month a great idea. As the essayist William Hazlitt wrote, “A gentle smile, a kind word, a good-natured smile can work wonders and accomplish miracles”.
1. Why is National Smile Month held in the UK?| A．To promote the health benefits of smiling. |

【推荐1】Be careful on January 8th —It's officially the most dangerous day of the year. The insurance（保险）company Hyperion has studied accident statistics（统计数字）and has found that there are more accidents on January 8th than on any other day.
Accidents are certainly more likely to happen at particular times of the year. One general rule is that more accidents happen in winter months, because risk increases in bad weather.
In 2004 and 2005 Hyperion found that the worst day was January 8th , with 298 accidents reported to them. March 3th was the safest day, with only 89 reports. Six of the ten worst days for driving were in January.
It's clear that icy and snowy conditions are dangerous, but some other statistics are puzzling. A British Medical Journal report in 2001, for example, found that hospital admissions were always higher than usual on Friday the 13th .
But it is not only when Friday falls on the 13th that it is a dangerous day. Four of the top ten worst days for accidents last year were Fridays-perhaps because everyone is rushing home for the weekend-while Thursdays are the safest day of the week.
At what time of the day is an accident most likely to happen? The Health and Safety Authority found that people are most likely to have an accident at 11:00 a. m. , while the safest time of day is between 4: 00 and 5: 00 a. m. —probably because most people are in bed!
Finally, good news for Harry Potter fans. Doctors at the John Radcliffe Hospital in Oxford noted that fewer children were in hospital on the weekend when Harry Potter books were available to the public. Deaths fell by over 50% when the last two books went on sale. So if you want to be really safe, you should read a Harry Potter book in bed. at around 5: 00 on a Thursday morning, in summer.

【推荐2】Should we focus on our goal, or on the process?
What happened to Brenda Martinez, a US Olympic runner, may provide us with the answer. She lost her balance in the 800-meter run and failed to qualify for the Olympics. Instead of focusing on her failure, she prepared to win in the next race. “I just quickly let go of what happened in the 800m and got back to my routine, to focusing on all the little things I could do that would give me the best chance of running well later in the week,” she told New York Magazine. She said it was this mindset that led to her winning third place in the 1500-meter race about a week later to qualify for the Olympics in Rio. Instead of attaching herself to the goal of making the Olympic team, she concentrated on the process.
There is a problem with setting goals. Researchers from Harvard, the University of Pennsylvania and Northwestern found that overemphasizing goals based on measurable outcomes often leads to risk-taking, unethical (不道德的) behavior and reduced motivation. Their results were published in a Harvard Business School report titled Goals Gone Wild: The Systematic Side Effects of Over-Prescribing Goal Setting.
When you become overly focused on achieving the goal, you may lose sight of your original purpose for accomplishing the goal in the first place. Another danger is actually completing the goal without setting a plan for what’s next. For example, some marathon runners experience what’s called the “post-race blues”. Achieving your goal may cause you to drop the good habits that got you there in the first place. Dieters often experience this in what’s called “yo-yo dieting” when they drop down to a desired weight, but then gain all the weight back when they resume (重新开始) their bad habits.
“After you set a goal, it’s best to shit your focus from the goal itself to the process that gives you the best chance of achieving it and to judge yourself based on how well you complete that process,” columnist Brad Stulberg wrote on the website The Cut.
Ultimately, changing your attention from goals to process will cause you to achieve little victories on your way to accomplishing long-term goals. Amy Cuddy, a Harvard Business School psychology professor, wrote that focusing on this process “leaves you with a sense of satisfaction and accomplishment, regardless of the measurable outcome”.

Chokwe developed the app with his friends Rodriguez Ratliff and Emmanuel Brooks. When the app detects a pothole, it is highlighted in red. And if you get close to the pothole, your phone will warn you with a beep. Drivers can also use the app to report any potholes and look for other routes they can take to avoid roads that have them.
The app relies on current available information about the streets of Jackson, already stored in a database of the city’s 311 call system. Through the call system, citizens dial 3-1-1 to report non-emergency problems which include potholes. Chokwe and his friends determined that focusing on the 10 busiest streets in Jackson would give them a large enough sample size to test the prototype.
While developing the app, the boys took part in a Minority Male Makers Program sponsored by Verizon and held at Jackson State University. They learned 3D printing and design, and how to create apps. Through the program Chokwe and his friends received encouragement and guidance.
Although the app isn’t yet available for sale, Chokwe is already looking for ways to improve the app. He hopes to add more to it until it spreads all over the country.
