1 . Independent living at home is the ideal for every aging person. But a fall or other health-threatening incidents can change everything rapidly.
The wearable “panic buttons” introduced in the late 1980s were a great advance. But they only work if people actually wear them and can reach the button in an emergency. Today there are passive wearables that automatically detect falls, and camera-based systems to monitor elder safety.
Coming from a 40-year career in the semiconductor and wireless communication field, Rafi Zack decided to find a better alternative. “People aren’t devoted to wearing small devices 24/7, and camera-based systems are an invasion（侵犯）of privacy,” he points out, “The most challenging aspect is a fall. How fast we can detect a fall matters because the medical situation worsens quickly. Sometimes people stay on the floor for a long time. We have to find out how to solve that problem.”
Zack is a co-founder, CEO and vice president of R&D at EchoCare Technologies which has developed ECHO (Elderly Care Home Observer), a cloud-connected monitor based on radar technology and machine learning.
Because radar sees through walls, one ECHO unit fixed on the ceiling or wall can monitor one person (or two persons, in a future version) in a standard-sized apartment in a senior living facility. The device detects falls, breathing difficulties, drowning in a bathtub and other dangerous events. It gives out warnings to potential health worsening conditions by continuously monitoring and analyzing the person’s location, posture（姿势）, motion and breath. EchoCare tested the device in the United States, Japan, Australia and Israel. ECHO was certified（认证）in 2019 in Japan with the most aging population in the world.
“Bathrooms were the main testing area where about 17,000 deadly accidents happen annually.” said SMK Director and Executive Vice President Tetsuo Hara. “Bathroom makers, home security service providers and nursing homes are highly interested in EchoCare’s solution.” Zack noted, “As more and more elder people live alone as a result of social distancing, there is an increased need to monitor them without the burden of wearables or privacy-invading cameras.”

2 . Young children who have experienced compassionate (有同情心的) love and empathy (认同感) from their mothers may be more willing to turn thoughts into action by being generous to others, a University of California, Davis’ study suggests.
In lab studies, children tested at ages 4 and 6 showed more willingness to give up the tokens (代金券) they had earned to fictional children in need when two conditions were present—if they showed bodily changes when given the opportunity to share and had experienced positive parenting that modeled such kindness. The study initially included 74 preschool-age children and their mothers. They were invited back two years later, resulting in 54 mother-child pairs whose behaviors and reactions were analyzed when the children were 6.
“At both ages, children with better physiological regulation and with mothers who expressed stronger compassionate love were likely to donate more of their earnings,” said Paul Hastings, UC Davis professor of psychology. “Compassionate mothers likely develop emotionally close relationships with their children while also providing an early example of satisfying the needs of others,” researchers said in the study, published in November in Frontiers in Psychology” Emotion Science.
In each lab exercise, after attaching a monitor to record children’s heart-rate activity, the examiner told the children they would be earning tokens for a variety of activities, and that the tokens could be turned in for a prize. The tokens were put into a box, and each child eventually earned 20 prize tokens. Then before the session ended, children were told they could donate all or part of their tokens to other children.
Taken together, the findings showed that children’s generosity is supported by the combination of their socialization experiences—their mothers’ compassionate love—and their physiological regulation, and that these work like “internal and external supports for the ability to act prosocially that build on each other”.
In addition to observing the children’s propensity (习性) to donate their game earnings, Hastings suggested that “being in a calmer state after sharing could reinforce (加强) the generous behavior that produced that good feeling.”

3 . Nearly everyone knows eBay is a website where you can buy and sell pretty much anything. There are other Internet auction (拍卖) sites, but none come close to eBay for brand-name recognition. And for good reason: eBay is the largest English-language online auction site in the world. Buyers come to eBay for the best chance of finding the particular thing they want. Sellers come for the largest pool of buyers, which they hope means the best chance of selling at the highest possible price.
Buying things on eBay is pretty simple. You can type a term into the search field, or click through the categories list to get to what you want. Inside an individual item listing, you’ll see the current asking price, and a little button to click if you wish to place your own bid. Enter a price, occasionally come back to see if someone has bid higher than you and wait for the end of the auction period. If your bid is the highest, you win! Now all you have to do is arrange payment and shipping method with the seller. eBay is only in the business of putting buyers and sellers together for a small fee from the seller. It doesn’t handle the actual payment or shipping of goods. In other words, it isn’t a big department store, or a warehouse. It’s the owner of a flea market, and you have to do your own deals with the individual sellers in their virtual stalls.
To be a skillful eBay buyer, you should learn when to trust sellers and how a proxy (代理人) bid can save you from going online every half-hour to up your bid. Experienced eBay users also know how to use escrows (公正托管) to guarantee goods, and how to avoid selling tricks such as fake bids that push up prices. The more often you buy on eBay, the more you learn.
1. Why is eBay the best website for people to buy and sell things?| A．Because it has all brand products. |
| B．Because the trade language is English. |
| C．Because sellers and buyers can close their deals. |
| D．Because sellers can find a swimming pool there. |
| A．Find the current asking price. |
| B．Click a button to place your own bid. |
| C．Enter a price which is higher than others. |
| D．Find what you want in the categories list. |
| A．Get goods from eBay. |
| B．Determine payment and shipment. |
| C．Send somebody for the goods. |
| D．Talk about the price of the goods. |
| A．How to be a skillful buyer at eBay. |

| C．How to avoid being cheated by others. |
| D．How to spare you from going online frequently. |
4 . The use of AI (artificial intelligence) is becoming more common in many branches of industry and online shopping. Traditional lines of work, such as goods transport and driving, are developing in a similar direction although mainly out of public view. Scientists at the University of Göttingen have now investigated how efficient (高效的) the use of AI can be in the commercial management of trucks.
“Digital applications—as well as machine leaning, a kind of AI—are increasingly applied to operations and courses in the transport area,” explains Professor Matthias Klumpp from the Faculty of Economics. “The question in the commercial area, however, is whether or not this contributes to achieving goals.”
To answer this question, the researchers compared the work efficiency of truck drivers with their main use of AI applications. Looking at trade delivery by truck, they studied three groups: the first drove completely following human decision-making models; the second used a combination of human and machine; and the third depended completely on fully automated decisions.
The researchers found that an intelligent combination of human work and decision-making abilities with AI applications promises the highest transport and driving efficiency. “On average, the second group achieved the most efficient transport trips, with the fewest interventions (干预) and off-course from the best path.” one researcher said, “Clearly, neither a completely human decision-making structure nor a fully automated driving system can promise to meet current goods transport requirements.” The scientists therefore summarized that despite the progress of AI in the field of transportation by truck, human experience and decision-making abilities will still be necessary in the longer term. However, the challenge is that a wide range of training and qualification (资格) needs will come along by working with Al applications, especially for simple goods transport activities.
1. What does Matthias Klumpp focus on?| A．The efficiency of AI. |
| B．The advantages of AI. |
| C．The problems caused by AI. |
| D．The wide applications of AI. |

5 . China was a latecomer to space exploration, and in the movies, it has been a latecomer to science fiction. That has probably changed.
The country’s first blockbuster (大片) set in space, The Wandering Earth, opened in February amid high expectations that it would represent the beginning of a new era in Chinese filmmaking. Shown in 3D, The Wandering Earth takes place in a distant future in which the sun is about to expand into a red giant and devour (吞食) the Earth. The approaching danger forces the world’s engineers to work out a plan to move the planet to a new solar system. Things go very badly when Earth has to pass Jupiter, setting off a desperate fight to save humanity from being totally destroyed.
The Wandering Earth is adapted from a short novel by Liu Cixin, the writer who has led a renaissance in science fiction in China. His works are great epics (史诗) and deeply researched. Translating them into movies would challenge any filmmaker, as the director of The Wandering Earth, Guo Fan, admitted.
Guo noted that Chinese Studios had been cautious about investing the resources required to make convincing science-fiction. The budget for The Wandering Earth reportedly reached nearly $50 million— modest by Hollywood standards but still significant in China. “I really hope this movie will not lose money at least,” said Guo before the movie’s release. The popularity of Liu’s novels could help. So could the fact that China has reached a milestone in space: the landing of a probe (航天探测器) on the far side of the moon in January. Although decades behind Russia and the United States, China has now put astronauts in orbit and has ambitious plans to join---or even lead---a new age of space exploration.
Unlike some typical Hollywood movies, The Wandering Earth does not feature a world-saving hero. The fight to save Earth is fought instead by a group. A vision of international cooperation to cope with the threats facing the Earth is a theme that runs deeply through Liu’s fiction.
1. What message does the success of the movie The Wandering Earth convey?| A．It lives up to the audience’s high expectations. |
| B．It marks a new height of the Chinese filmmaking industry. |
| C．It displays China’s ambition to lead space exploration. |
| D．It sets new and higher standards for Chinese movies. |
| A．giant investment of Chinese studios | B．the high reputation of the film director |
| C．China’s advances in space exploration | D．the deep research and world-saving theme |
| A．A New Era for Space Exploration Begins |
| B．A Film Based on Liu Cixin’s Novel Enjoys Great Popularity |
| C．China’s First Space-Themed Film Features Cooperation |
| D．China’s Film Industry Eventually Joins the Space Race |
6 . With the social media freely available, I've realized how easy it is to become a jealous cow. The truth is that however much I remind myself of the many wonderful things I have in my life, there are still moments when I look at those around me and feel bitterly upset by their success.
It's a horrible thing to admit! In an ideal world, I'd never want to be jealous of another person's achievements and I'd want to celebrate the successes of my friends. But sometimes it's hard, even when we want to. But I don't want to live my life as a jealous cow, and I assume you don't either.
It's easier to celebrate other people's wins if you celebrate your own. How often do we take the time to enjoy our success rather than instantly move onto the next thing we want to achieve? Last year, I decided to write a book. It was the only professional goal I set for myself and, while it tired me out, I got there. But as soon as it was done, I started planning my next goal-making the book a success. As I saw other people publishing books, I stopped celebrating and instead began to fear that mine wouldn't compete.
When I told a friend how I was feeling, she reminded me how much easier it is to clap for someone else when we also clap for ourselves. So, I took myself out for lunch, ordered a glass of wine and wrote myself a congratulations card. When I saw all those other books being written on my social media, I felt proud of each and every one of us who had battled to the end of the word count.
The other trick for celebrating other people's success is to realize that there is no limit on success. We can make more, which means that while it might seem as if others have everything and we have nothing, the reality is that life turns quickly and our luck could change at any time. If others have achieved those things, we can too. When we celebrate others, we're acknowledging their achievements but also cheering for ourselves as well as for our hopes and dreams and our belief that we can make them happen. And hopefully, when we do, those people will cheer for us too.

7 . A new product from Google may help people solve their sleep problems, but some privacy rights groups are concerned.
Google showed off its newest Nest Hub home assistant device on Tuesday. In addition to recognizing your voice, showing pictures, videos, news and weather, it can also track your sleep. The basic model costs about $100 and the sleep-tracking technology will be available for free for the rest of 2021. The sleep tracker makes Google’s product different from a similar home assistant from Amazon. If you put the Nest Hub beside your bed, it can follow how you sleep. That is because of a new computer chip called Soli, which can sense motion. Some people may like the new technology because they would not have to wear another device to bed. Some companies make products people can wear on their wrist to track their sleep.
Google says the new Nest Hub will create reports each week that show how long and how well a person sleeps. It will also show if they snore, cough or wake up often. The company said it studied 15,000 people over the course of 110,000 nights to develop the technology.
For people who want to know more about their sleep, the device sounds like a good idea. But, people who pay attention to privacy are worried what Google might do with the information it is gathering. Jeff Chester is one of those people. He is the director of the Center for Digital Democracy. “Google’s goal is to monetize every cell of your body,” he said.
Google recently bought FitBit, a company that makes a health tracker people can wear on their wrist. Some technology experts think Google may find a way for the Nest Hub to work with the FitBit.
Google says the sleep tracker has a lot of privacy protections. For example, it will only work if the user turns it on. The company said it will not use a person’s sleep information to try to sell advertising. But Chester said he is not so sure that promise will be kept.
1. Which is true about the Google’s new Nest Hub?| A．It’s the first device to track people’s sleep. |

8 . Have you ever heard about Black Friday and Cyber Monday? Surely, they are all about finding the best deals on holiday gifts for yourself and family members. And have you heard about GivingTuesday? Here is something about it!
GivingTuesday is observed annually on the Tuesday after Thanksgiving, which encourages people to help those in need by making financial donations or doing good in their local community. The “Global Day of Giving” was started in 2012 by New York City nonprofit 92nd Street Y and the United Nations Foundation.
Unlike Black Friday, GivingTuesday serves a more altruistic purpose. In its first year, the movement brought in almost $10 million for charities, and things have only improved since. In 2019, many GivingTuesday social media campaigns worldwide helped raise an amazing $ 1.9 billion from 27 million donors! Over the past five years, many higher education institutions have also been using the Tuesday after Thanksgiving to ask alumni for donations. In 2019, the University of Michigan, which calls it Blueday, received 5887 gifts totaling over $4 million, while Pennsylvania State University raised $710 000 to benefit over 85 University programs.
Though donating money certainly helps, there are many other ways to support the great cause, especially during the COVID-19 pandemic. You can video tutor kids struggling with online learning, or team up with an adult to get groceries or medications for an elderly neighbor. Alternatively, call on your peers to help you with a service project that addresses an issue close to your heart, or pick one from the several ideas suggested on the GivingTuesday website. You can also donate your gently-used clothes and toys to local shelters, or mail a handwritten note to a grandparent or a friend you miss seeing.

9 . In previous recessions (经济衰退), billionaires were hit along with the rest of us; it took almost three years for Forbes’s 400 richest people to recover from losses caused in 2008’s Great Recession. But in the coronavirus recession of 2020, most billionaires have gotten richer than ever before.
Billionaires increased their new billions just as millions of other Americans ran into terrible financial problems. More than 20 million people lost their jobs at the start of the pandemic. Food banks across the country are preparing for another great increase in demand. Why are American billionaires doing so well while so many other Americans suffer? People may find part of the reasons from the following fact. Stocks (股票) are overwhelmingly owned by the wealthy, and the stock market has recovered from its early-pandemic depths much more quickly than other parts of the economy.
But some billionaires are also benefiting from economic and technological trends that were accelerated by the pandemic. Among these are the owners and investors of retail giants like Amazon, Walmart, Target, Dollar Tree and Dollar General, which have reported huge profits this year while many of their smaller competitors were defeated completely as the coronavirus spread.
Then there are companies that have bet on the rapid digitization of everything Eric Yuan, the chief executive of Zoom, became a billionaire in 2019. Now he is worth almost $20 billion. Dan Gilbert, the chairman of Quicken Loans, was worth less than $7 billion in March, now he commands more than $43 billion. But there is a great deal of stratification (层化) even among billionaires—richer billionaires got even richer in 2020 than the poorer ones did. Jeff Bezos, Amazon’s funder, was worth about $113 billion at the start of the pandemic. Now he is worth $182 billion. Two years ago, Bezos was the only “centibillionaire” on earth—the trendy neologism (a new word) for people whose wealth exceeds (超过) ￥100 billion.

10 . Morgan’s Wonderland, located in San Antonio, Texas, is a theme park mainly intended for mentally or physically disabled children. The park was built by Gordon Hartman, a former real estate (房地产) developer. The creation of the park was inspired by his daughter, Morgan, who suffers from severe cognitive delay and physical challenges.
The world’s first ultra-accessible family fun park, Morgan’s Wonderland opened in the spring of 2010. Admission for guests with special needs is free, and fees for the general public are set at a much discounted price so that people of all ages and abilities can come together and play in a fun and safe environment.
Completely wheelchair-accessible, the park features 25 acres of attractions including rides, playgrounds, a catch-and-release fishing lake, and picnic areas throughout the park. The rides are custom-designed to accommodate wheelchair riders so that every family member can enjoy the fun. The adapted rides include the Off-Road Adventure, where guests can test their driving skills in sporty vehicles. Moreover, each visitor is offered the option to wear a GPS Adventure Band, which allows them to keep track of each other while in the park. The band also enables them to take part in electronic activities. For example, when the riders scan the band at the Off-Road Adventure, a photo will be taken and sent to their email.
In June 2017, Morgan’s Wonderland celebrated the opening of Morgan’s Inspiration Island. The new expansion is composed of five themed splash pads and a River Boat Adventure Ride. The wheelchair guests can be moved out of their chairs into unique, waterproof chairs and enjoy the splash park without risking damage to their personal wheelchairs.
“Morgan taught me that there’s more to life in many ways than what I saw before,” said Hartman. “The blessing that Morgan has brought is beyond anything that I ever could have imagined and could explain.”
