1 . A US government study has found that facial recognition technology is getting better at identifying people wearing masks. The study is part of an ongoing research by the US National Institute of Standards and Technology (NIST). The agency has examined the effectiveness of more than 150 facial recognition systems on people wearing face coverings . The systems are powered by machine learning algorithms (算法).
The first results of the study were announced in July, as health officials across the world urged people to wear masks to limit the spread of COVID-19. New findings were released this week . Police agencies have long used facial recognition technology to search for and help catch criminals. It can also be used to unlock phones or other electronic devices. Some robots use facial recognition technology to recognize the people they are communicating with. However, the wide use of masks in public has created major difficulties for such systems.
The study looked at facial recognition systems already in use before the pandemic. It also looked at systems specially developed to work on masked faces. The NIST said it processed a total of 6. 2 million images for the experiment People in the images were not actually wearing masks. So, the researchers digitally added different mask shapes to faces in the pictures for use in the study. In some cases, up to 70 percent of a person’s face was covered in the images. Overall, the research shows the top-performing facial recognition systems fail to correctly identify unmasked individuals about 0. 3 percent of the time and the failure rate rose to about 5 percent with masked images. Many of the lower performing algorithms, however, had much higher error rates with masked images — as high as 20 to 50 percent.
In the latest findings, researchers included results from 65 new facial recognition systems that have been developed since the start of the pandemic. “Some of these systems performed “significantly better” than the earlier ones，” Mei Ngan, a lead researcher on the project, said in a statement. The study also found round-shaped masks — which cover only the mouth and nose — led to fewer errors than wider ones that stretch across the cheeks. The new study also ran tests to see whether different colored masks would affect error rates. The team used red, white, black and light blue. The research findings suggested that generally, the red and black masks led to higher failure rates than the other colors.

2 . Aunt Fannie was Blueberry Jam Woman. Of course she wasn’t really my aunt, and out of fear, I never called that to her face. The name always made my father chuckle (轻笑) and my mother look sternly (严厉地) at both of us—at me for being disrespectful, and at my father for encouraging my bad behavior. I enjoyed both reactions, so I looked for every opportunity to work for the name into conversation.
As a young woman, my mother had worked in the kitchen of a large Victorian farm house owned by Fannie Cratty. Fannie was the last of the Cratty line; she had never married, and had no living heirs(继承人). My father once told me that it was because she was too mean to share her family wealth or pass it on. Aunt Fannie was noted for her jam, and for never sharing the recipe with another living soul. Even though my mother knew it by heart, as long as Aunt Fannie was alive, she never made the jam without Miss Cratty in our kitchen to direct the process and preserve the secret.
One year, after I had been particularly helpful with the jam-making process. Aunt Fannie gave me a quarter and then made me promise I would never spend it. “Hold onto this quarter,” she said, “and some day you will be rich. I still have my first very quarter.” It had obviously worked for her, so I put that 1938 quarter in a small box,put it in my dresser drawer, and waited to become rich.
I now have the blueberry-jam recipe and the quarter from Aunt Fannie. Neither has significantly contributed to my wealth, but I keep them to remind myself to hold onto the valuable things in life. Money can make you feel rich for a while, but it is your relationships, and your memories of time spent with friends and family, that truly leave you wealthy. And that is a fortune that anyone can build.

3 . Lizard (蜥蜴) species may already have declined past the point of no return in the world. What is the reason? Rising temperatures. Researchers estimate that as much as 40 percent of lizard species worldwide will die out by 2080. The problem is that temperatures in many regions where lizards live have changed too fast for the animals to keep pace.
Barry Sinervo from the Department of Ecology and Evolutionary Biology at the University of California in Santa Cruz, along with colleagues from across the globe, reached that conclusion by taking current data on Mexican lizards. They also estimated that 4 percent of local species have already disappeared worldwide. That number could jump to 20 percent by 2080 if carbon dioxide levels aren’t lowered to reduce warming.
The team looked 48 species of Sceloporus lizard at 200 sites around Mexico. The sites were first sampled from 1975 to 1995. By 2010, research could not find lizards at 12 percent of those sites.
Lizards that bear live young are especially at risk of dying out, the researchers point out, compared to that lay eggs. “Live-bearers have lower body temperatures that heighten the risk of dying,” Sinervo said in a statement. We are watching these species disappear before our eyes.”
Although current evidence shows that climate change is affecting the habitat ranges of many species, there is still a lot of uncertainty about how much climate change will affect species, researchers say.
Many Mexican lizard species live in high altitude “islands”, where climate change happens the fastest. The lizards cannot adjust fast enough to survive. The scientists say they do not think the animals are likely to save themselves just by moving somewhere else either.
“How quickly can Earth’s lizards adapt to the rising global temperatures? That’s the important question,” Sinervo said in a press release. "We are actually seeing lowland species moving upward, slowly driving upland species out of their habitats. If the upland species can’t evolve fast enough, they will die out.”

4 . Kindness
Good friends are not just kind to you; they are kind to others as well. People like being around them because they are positive people. The kindness they spread comes from inner feelings of happiness and self-confidence. In contrast, social aggression, such as meanness, is a quality that shows lack of respect for others and discontent with oneself. These feelings outwardly show and eventually prevent communications and genuine friendships from forming.
Accepting
Good friends are easy to talk to because they accept what you are. They understand the things that are important to you and the values that you hold. Although they may not necessarily agree with all of your beliefs and actions, they will never judge you. People who can accept you also are better able to accept themselves. High self-esteem and self-acceptance are intertwined.
Interest
According to American writer and lecturer, Dale Carnegie, showing genuine interest in others is one way to promote feelings of goodwill. People are more likely to remember how you make them feel. This goes beyond good listening skills. Good friends ask questions about things that matter to you. To do this, they must put aside their own needs and focus on helping others feel important. If you make them feel inferior, they will not enjoy the time you spend together.
Honesty
Although honesty is important to friendships, it may be one of the most difficult qualities to maintain. When you ask a friend for honesty, she may prefer preserving the peace over telling you what she really thinks. But honesty promotes trust. A good friend cares enough to tell you the truth and has sufficient confidence in the relationship to be assured of a positive outcome.

5 . We've seen a worldwide health crisis (危机) bring out the worst in some people, but fortunately, we've also been able to see it bring out the best in others.
A taxi driver in Spain has been providing COVID-19 (新冠肺炎) patients with free rides to and from the hospitals. Doctors and nurses wanted to surprise him with their thanks for helping out.
They tricked him down to the hospital under the pretense of needing to pick up a sick patient, but in reality, doctors and nurses lined the hall waiting to applaud (鼓掌) him.
“This is a surprise that has been given to a taxi driver who takes patients to the hospitals without charge,” wrote the taxi company that first shared the video.
The man seemed completely taken aback by the gesture, stopping in the middle of the doors as the whole room cheered for him.
He was also given an envelope full of money and the satisfying results of his own COVID-19 test.
The video has since been shared tens of thousands of times across the world, because kind gestures break the language barrier (障碍).
“When the crisis is finished, there will have been two types of people... the good and the bad,” one user wrote. “With workmates like him, I am proud to be a taxi driver, son of a taxi driver, and father of a taxi driver.”
With the word in hard times, just knowing good people are there doing good deeds is something we can all appreciate.

6 . It was late, about 10:15 p.m, when Janice Esposito arrived at the New York train station and began the 20-minute drive home. She had traveled the route so many times that she almost drove on autopilot (自动驾驶):a left onto Station Road, then a left on Montauk Highway, and then-bang! Out of nowhere, a car T-boned Janice’s car, pushing her backward onto the railroad tracks.
As it happened, Pole DiPinto was gelling ready for bed. He'd just closed his book when he heard the loud crash not far outside his bedroom window. A volunteer firefighter and retired teacher, 64, never stopped to think, He grabbed a flashlight and still in his pajamas (睡衣), ran out the door. “Any firefighter would have? done what I did,” he said, “We're always on duly.”
The first car he came upon was the one that had hit Janice. Once DiPinto concluded the driver was OK, he looked around and spotted Janice's car lay across the railroad tracks. And then he heard a terrible sound: the bells signaling an on-coming train.
DiPinto rushed to Janice's cur and banged on the driver's side window. She just looked at him, her eyes unfocused. “I don't know where I am,” she said. She seemed unhurt. “Honey, you're on the railroad tracks,” DiPinto shouted, “We have to get you off right now!” He pulled hard on the door handle, but it didn't work. The heavy train, traveling at 65 miles per hour, was heading toward them. DiPinto ran to the passenger side and threw open the door. “Please, God, don't let her be trapped”, he thought. He pushed aside the airbags, grabbed Janice's arms, and pulled her toward him across the passenger seat until he could help her out and walk her to safety. Within six seconds, he estimated, the train crashed into the car.
“It was like a Hollywood movie,” DiPinto told reporters the next day. But this one had a difference. That night, the hero arrived in pajamas, not in a fire truck.

7 . The year I turned fifty, I resolved to do something new every day. However, balancing 365 new things with work and family, while still managing to do the laundry and get dinner on the table every night, was not always easy. In the early weeks of the project, I found it difficult to find so many new things.
It wasn’t long before my friends learned that I was open to almost anything I could consider a new thing, and the invitations began pouring in not just from friends, but friends of friends. As a result, my life was new. I went dog sledding. I attended a fashion show. I went to numerous lectures on all kinds of topics that I never would have previously considered useful or interesting and found something to appreciate in every single one. I even signed up immediately when learning about a local group trying to get into the Guinness Book of World Records by doing something unusual.
As time went by, whenever I learned about something that seemed remarkable, I did what I could to pursue it. Instead of “Why”, I began to ask “Why not”. Now I find it is easier to just keep my eyes open to the possibilities that surrounded me. It turned out that there were new things everywhere, and all I had to do was make a little effort to enjoy them.
I looked back on the year. It doesn’t matter to me that many of my “new things” weren’t exactly meaningful. What matters is how to make full use of them when discovering there is an endless number of new things for me. It seemed to me an obvious sign that at fifty, my life was full of promise. I could continue to grow, stretch my wings, and learn more every day for the rest of my life. I enjoyed the idea of something new, and it gave me a reason to welcome each day as an opportunity to experience the world a little differently.

8 . According to a new study from Cornell University, about one-fifth of the global population, of 2 billion people worldwide, will be forced to resettle or go deeper inland by 2100 due to the continuous rise in sea level.
The study, published in the journal Land Use Policy, showed that the growing global population could make the matter worse. The researchers expected that there are about 1.4 billon “climate change refugees(难民)” in the world by 2060 and by 2100 the number of the displaced people due to the rising sea level could reach up to two billion.
“We’re going to have more people on less land and sooner than we think,” said lead author Charles Geisler, professor at Cornell. “The future rise in global average sea level probably won’t be gradual. Yet few policy makers are observing the significant barriers that coastal climate refugees, like other refugees, will run into when they move to higher ground.”
For the study, the researchers reviewed(回顾) potential problems that climate change refugees may face if they go deeper inland. The researchers identified these land difficulties with relocation using three organizing groups. Including depletion(损耗) zones, win-lose zones and no-trespass(不得擅自进入) zones. By doing so, the researchers were able to provide primary estimates of their toll(损失) on inland resettlement space. The researchers found that some inland regions were unlikely to support new waves of climate change refugees due to the remains of war, road developments and rare natural resources.
Apart from the rising sea level, increasing storm weather and the booming global population are also having a huge influence on the number of climate change refugees. Storm can push seawater further inland. The increasing global population requires more land even as the ocean swallows up rich costal zones and river deltas(三角洲). These force people to search for new places to move to higher ground.
1. What would happen if the sea level were to rise?| A．2 billion people would be “refugees” by 2060. |
| B．50% of the population would lose their homes. |
| C．Inland regions would become more crowded. |
| D．Coastal regions would be polluted seriously. |
| A．The sea level will go up in a little-by-little way. |
| B．Moving to higher land isn’t the key solution. |
| C．Land and population vary according to climate change. |
| D．Policy makers should think more for climate change refugees. |
| A．Because they can’t live a common life there. |
| B．Because they can’t adapt to the climate there. |
| C．Because they may consume more than expected. |
| D．Because they will destroy the natural resources. |
| A．Global warming is a double-edged sword. |
| B．In the future climate will become worse. |
| C．The earth will see more climate change refugees. |
| D．Sea will bring humans more disadvantages. |
