1 . Robots are getting better at doing human jobs. That's probably good for the economy—but there are some serious downsides, too.
Machines are expected to displace about 20 million manufacturing jobs across the world over the next decade, according to a report released by Oxford Economics, a global forecasting and quantitative analysis firm.
That means about 8.5% of the global manufacturing workforce could be displaced by robots. The report also notes that the move to robots tends to create new jobs as fast as it automates them; however, it could contribute to income inequality. The use of robots is on the rise: at this point, every new robot that is installed (安装) displaces 1.6 manufacturing workers on average, according to the Oxford Economic model.
Robots are becoming cheaper than many human workers, in part because of the falling costs of machines. And they are increasingly capable of functioning in more complex processes and varied contexts. On top of that, the demand for manufactured goods is rising.
One potential downsize to the robot revolution: automation could increase income inequality. "This great displacement will not be evenly distributed around the world, or within countries," according to the report. "Our research shows that the negative effects of robotization are disproportionately (不成比例地) felt in the lower-income regions compared with higher-income regions of the same country."
The workers who drive knowledge and innovation within the manufacturing industry tend to be concentrated in larger cities, and those skills are harder to automate. That's why urban areas will deal better with the increased automation, according to the report.
On the whole, the increased use of automation will likely create new jobs at a pace comparable to the jobs that will be lost, which cancels out fears about permanent job destruction, according to the Oxford study. That said, the poorer regions that are expected to lose the most jobs will probably not benefit equally from this new job creation due to a gap in skills. That will lead to increased income inequality between cities and rural areas, as well as between regions.

2 . 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. "

3 . The winter had been busy and long. I desperately needed a getaway from work, so I decided to book a trip to the Caribbean with my wife. But just three days before my trip， the human-resources manager of the company called and asked to speak with me in his office. I sensed something wrong. Just months shy of my ten — year anniversary with the company, I was laid off.
I was in complete shock — too shocked to even cry. But I wouldn't cancel my trip, as I needed it now more than ever. The night before my trip, I had a dream that the suitcase I had brought to the hotel was empty. When I woke, I interpreted this dream to mean that I was leaving all of my “baggage” behind — and I did. I enjoyed my vacation more than any others I had taken. And when I was back, I decided to do one thing I loved but never had the spare time to do: writing.
My works had never been published, but I wanted to try. I wrote a few pieces and sent them out to magazines and newspapers. After several non-responses and rejections, the most-read newspaper in Canada agreed to publish one of my travel stories. I shared the thrilling news with my family and friends. People I hadn't talked to in years contacted me to tell me they read my story. How amazing!
I started writing because I liked it. What I didn't realize was that my first published story would open several doors. Being published in a major publication made my resume impressive and led to interviews for writing positions. It also led to more publications noticing the articles I submitted. I am satisfied that now I work full-time as a corporate writer and my works have been published in a number of magazines.
Getting laid off was an experience that could have been fatal （毁灭性的）,But there was something about that dream after it happened. That dream helped me put everything behind me and gave me the confidence to pursue new possibilities.

5 . The definition of community has evolved (升华)for me from childhood to the young adult I am now. My mom was born in America but both her parents were from the Bahamas. It was their culture to take care of the elderly and the sick. And my mom has taught me to be caring to those around us because we're all a part of the "community" , an extension of family.
When I was 9 years old, my family moved to Cape Coral, Florida. Both mom and dad worked full-time, so they registered me to attend an after-school program at the Youth Center. Youth counselors (辅导员) would help me with my homework and play games with me and this was where my interest took root. Community service started with me giving back at the Youth Center.
Then illness struck at home. My grandmother had to have heart surgery and needed hospital treatment. This experience brought me to volunteer at Cape Coral Hospital. I asked if I could learn from the nurse how to give my grandma her medicine and it started here.
I loved being at Cape Coral Hospital. I would bring paperwork to other doctors, bring food to the patients, and make sure the patients were attended. I would help direct visitors to see patients. I would always tell what would cheer the patients up because I had built a relationship with them and their loved ones. I grew to feel the hospital was a part of my community.
After volunteering at the Youth Center and at the Hospital, I've learned that people become sort of an extended family when you care about them. Now I am more considerate of those close to me, neighbors and even strangers who share my resources.

6 . At any moment, about half the world's population is wearing denim （牛仔布）. But few realize tiny bits of denim have been adding up to a surprising amount of pollution in water, as a new study shows.
Sam Athey, one of the study's authors, says, “Even though denim is made of a natural material — cotton — it contains chemicals. " Cotton fibers are treated with many types of chemicals, she notes. Some improve its durability and feel. Others give denim its distinctive blue color.
Athey and her team washed jeans and found that about 50,000 microfibers come off from each pair per wash. Not all of those fibers make their way into the environment. Wastewater treatment plants catch about 83 to 99 percent of them. Catching 99 percent may sound pretty good. But one percent of 50,000 is still 500 fibers per wash. And since every pair of jeans is washed again and again, it still adds up to lots of microfibers entering water environments.
Denim microfibers showed up in sediment （沉淀物）from the Great Lakes. More of these fibers polluted a series of shallow lakes in southern Ontario. They even turned up in sediment from the Arctic Ocean in northern Canada. The team found denim accounted for 12 to 23 percent of microfibers in the sediment. There were other microfibers too. But the team focused on denim because so many people wear jeans.
"Everyone wears jeans so they could be our largest input of microfibers into our streams and soils,“ Athey says. "An easy way to limit that is by washing our jeans less often.” Athey grew up thinking she should wash her jeans after every couple of wearings, but most jean companies recommend washing them no more than once a month “The solution is not that you shouldn't wear jeans," she says. "We need to buy fewer denim clothes and only wash them when they truly need it. ”

8 . Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, texting or checking updates on WeChat without looking at what was going on around them. As the number of this new “species” of human has kept rising, they have been given a new name — phubbers (低头族).
Recently, a cartoon made by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities（身份）are buried in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes selfie (自拍照)in front of a car accident site, and a father loses his child without knowing about it while using his mobile phone. A chain of similar events eventually leads to the destruction of the world.
Although the ending sounds overstated (夸大), the damage phubbing can bring is real. Your health is the first to bear the effect and result of it. “Continuously stretching (伸展) your head to check your cell phone could damage your neck,” Guangming Daily quoted doctors as saying, “the neck is like a rope that breaks after long-term stretching.” Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report.
But that’s not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to（往往） stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.
It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed (抢劫) of their cell phones in broad daylight.

10 . The end of the school year was in sight and spirits were high. I was back teaching after an absence of 15 years, dealing with the various kinds of "forbidden fruit" that come out of book bags. Now was the spring of the water pistol.
I decided to think up a method of dealing with forbidden fruit.
"Please bring that pistol to me," I said. "I'm going to put it in my Grandma's Box."
"What's that?" they asked.
"It's a large wooden chest full of toys for my grandchildren," I replied,
"You don't have grandchildren," someone said.
"I don't now." I replied. "But someday I will. When I do, my box will be full of wonderful things for them."
My imaginary Grandma's Box worked like magic that spring, and later. Sometimes. students would ask me to describe all the things I had in it. Then I would try to remember the different possessions I supposedly had taken away—since I seldom actually kept them. Usually the offender would appear at the end of the day, and I would return the belonging.
The-years went by, and my first grandchild Gordon was born. I shared my joy with that year's class. Then someone said, "Now you can use your Grandma's Box." From then on instead of coming to ask their possessions back, the students would say, "That's okay. Put it in your Grandma's Box for Gordon."
I loved talking about the imaginary box, not only with my students but also with my own children. They enjoyed hearing about all the forbidden fruit I had collected. Then one Christmas I received a surprise gift—a large, beautifully made wooden chest. My son Bruce had made my Grandma's Box a reality.
