Walmart will soon use 360 robot cleaners across a few hundred of its stores. Using maps input by human employees, the AI-powered cleaners will travel in the store with no difficulty, sweeping the floor--just as human employees used to do.
Perhaps the most striking thing about these robot workers is how not-striking they are. Sci-fi movies suggest a future full of human-like robots who appear with their horrible qualities. Now the future is coming into view, and it looks like a giant lie. It's easy to imagine walking past an Auto-C on a shopping trip without even noticing its presence.
AI has already started to become a part of our everyday life. In New Jersey this week, dozens of workers were hospitalized after a robot at an Amazon fulfillment centre accidentally broke a can and enveloped workers in eye-and-lung-damaging gas. Days earlier in California, an auto-piloted Tesla drove a drunk, sleeping driver down a highway, which no doubt did some potential risk to the other drivers on the road. Highway patrol officers figured out on the spot how to stop the AI car.
Of course, industrial accidents and drunk drivers existed well before AI. Tools with the power to release the burden of physical labor—horses, steam machines, self-driving cars—also come with the power to injure. And the presence of AI-powered machines just steps away from us is, for now, still a rare thing for most people.
But the nature of robots’ coming into our daily life lives will make it harder to recognize—or object to—the bigger changes they bring later. Walmart insists that the robot cleaners give employees more time for customer service and other tasks. Critics point out that they could just as easily become an excuse to reduce staff and wages.

【推荐1】We may weep for the dodo, but could and should we bring this lovely bird back from the dead? De-extinction is the science of restoring lost species and it has been in the news for decades.
The story in modern times began in 1990 when Michael Crichton published his science fiction novel Jurassic Park, in which he imagined a world where scientists were able to bring dinosaurs back to life. Crichton imagined that polymerase chain reaction (PCR) technology could be a way to amplify (放大) tiny quantities of dinosaur DNA and thus build a living embryo.
Sadly, biologists soon realized that DNA in fact breaks down super-fast; even after 100 years, DNA from museum skins of dodos was decayed (腐烂) beyond repair. They could be sequenced (测定序列) using massive computational power, but then only with considerable uncertainty. And even if you capture a DNA sequence, there’s still the problem of how you get living cells to read that sequence and express proteins that make the dinosaur or the dodo.
But why would anyone want to see mammoths, or something like them, roaming (漫游) present-day Siberia? Well, they were undoubtedly amazing beasts. As well as hunting them, our distant ancestors painted their likenesses in caves across Europe. Fascinating as they may be, there's some ecological justification for the project too.
It was this diversity of land surface, broken up by heavy limbs and randomly fertilised by faeces (排泄物), that supported so much flora (植物群). Without the mammoths, that diversity disappeared. Return them and landscapes would once again be with a variety of species, including flowers and bushes.
True, it’s not de-extinction in the sense of bringing a long-dead species back to life. Instead it’s more like making a “dodo” by engineering a modern pigeon, its closest relative, to become huge and flightless. The result would be a big, fatty pigeon that, whether it looked like a dodo or not, would probably fulfil some of its ecological roles.
As a palaeontologist, I would of course love to see living dinosaurs, mammoths and dodos. In some ways, though, I am relieved that the optimistic claims for cloning and genetic technologies have not been borne out. The slowdown gives us time to consider the outcomes—and hopefully avoid some of Michael Crichton’s more fevered imaginings.

【推荐2】Just how bad of a mother am I, I silently wondered, as I watched my 13-year-old son deep in conversation with Siri. Gus has autism (自闭症), and Siri, Apple's “intelligent personal assistant” on the iPhone, is currently his BFF(Best Friend Forever). Obsessed with weather formations, Gus had spent the past hour exploring the difference between isolated and scaltered thunderstorms—an hour during which, thank God, I didn't have to discuss with him myself. After a while I heard this:
Gus:“You're a really nice computer.”
Siri:“It's nice to be appreciated.”
Gus:“You're always asking if you can help me.Is there anything you want?” Siri: “Thank you, but I have very few wants.”
Gus: “OK. Well, good night!”
Siri: “See you later!”
That is Siri. She does not let my communicatively impaired son get away with anything. When Gus discovered there was someone who would not only find information for him related to his various obsessions but would also be willing to tirelessly discuss these subjects, he was hooked.
She is also wonderful for someone who does not pick up on social cues: Siri's responses are not entirely predictable, but they are predictably kind—even when Gus is rude. I heard him talking to Siri about music, and Siri offered some suggestions. “I don't like that kind of music.” Gus snapped(厉声说). Siri replied, “You're certainly entitled to your opinion.” Siri's politeness reminded Gus what he owed Siri. “Thank you for that music, though.” Gus said.
My son's practice conversations with Siri are starting to translate into increased facility with actual humans. Yesterday I had the longest ever conversation with him. Admittedly, it was about different species of turtles which might not have been my choice of topic, but it was back and forth, and followed a logic. For most of my son's 13 years of existence, this has not been the case.
Indeed, many of us wanted an imaginary friend when we were young, and now we can all have one not entirely imaginary anytime we wish to. In a world where the commonly held wisdom is that technology isolates us, it's worth considering another side of the story.
The developers of intelligent assistants recognize their potential usefulness for those with speech and communication problems, and some are currently pondering new ways in which the assistants can help. “For example, the assistant would be able to track eye movements and help the autistic learn to look you in the eye while talking." said William Mark, vice president of the company from whom Apple purchased the technology behind Siri. “See, that's the wonderful thing about technology. Getting results requires a lot of repetition. Machines are very, very patient."

【推荐3】A trial project by the Montreal Children's Hospital suggested that the use of medical hypnosis(催眠) can reduce pain and anxiety in patients. The project also resulted in a reduction in the amount of medicines used to perform medical-imaging (医学影像) procedures.
“During the examination children don't move. It works perfectly. It's amazing,“ said Johanne L'Ecuyer, a medical-imaging technologist at the hospital.
The project was inspired by a French team from Rouen University Hospital Centre where examinations are done under hypnosis instead of general anesthesia(麻醉).
A French medical-imaging technologist— also a hypnotist — was invited to train a few members in the medical-imaging department of the children's hospital. In all, 80 examinations were conducted for the project between January and September, 2019, focusing on the imaging procedures that would cause anxiety.
Hypnosis is not a state of sleep: It is rather a modified(改变的) state of consciousness. The technologist will guide the patient to this modified state—an imaginary world that will disassociate itself more and more from the procedure that follows.
“The technologist must build up a story with the patient," Ms. L'Ecuyer said. "The patient is left with the power to choose what he wants to talk about. Do you play sports? Do you like going to the beach? We establish a subject that we will discuss throughout the procedure."
Everything that happens next during the procedure must be related to this story — an injection(注射) becomes the bite of an insect; the heat on the skin becomes the sensation of the sun and a machine that rings becomes a police car passing nearby.
“The important thing is that the technologist associates what is happening outside the patient's body with what the patient sees in his head," Ms. L'Ecuyer said. "It requires creativity on the part of the technologist, imagination, a lot of patience and kindness."
The procedure appealed to the staff a lot when it was introduced in January. It spread like wildfire that someone from France was here to train the technologists," Ms. L'Ecuyer said. She added that she had a line of staff at her door wanting to take the training.

【推荐1】For reasons that are deeply rooted in culture and tradition, men significantly outnumber (比... 多)women in mathematics-based careers. As students progress through the mathematics courses, girls and boys show little difference in ability, effort, or interest in mathematics until adolescent years when course and career choices begin influencing school effort. Then, as social pressure increases and career goals are formed, girls' decisions to reduce effort in the study of mathematics progressively cut them off from many professional careers in the future.
Many girls drop mathematics in high school or in the transition to college. Others drop out later. Women perform virtually as well as men in college mathematics courses, but beyond the bachelor’s degree women drop out of mathematics at twice the rate of men. Women now enter college nearly as well prepared in mathematics as men, and 46 percent of mathematics baccalaureates (学士学位)go to women. Despite this record, only 35 percent of the master's degrees and 17 percent of the Ph. D degrees in the mathematical sciences are earned by women.
Overall, women receive approximately one third of university degrees in science and engineering. The highest percentages of women are found in those sciences with the least mathematical prerequisite: psychology, biology, and sociology. The lowest percentages of women enter fields requiring the most mathematics, namely, physics, engineering, economics, geo- science ,and chemistry. Evidence from many sources suggest that it is differences in course patterns rather than lack of ability that matter most in limiting women's access to careers in mathematically intensive sciences.
Widely reported studies concerning the high percentage of boys among mathematical prodigies (天才)---those who at age 12 perform at the level of average college students-often convey the impression that gender differences in mathematics are biologically determined. But evidence from the vast majority of students shows almost no difference in performance among male and female students who have taken equal advantage of similar opportunities to study mathematics. Inferences from very exceptional students——child prodigies—mean little about the performance of the general population.

【推荐2】“When your mother scolds you, you can look elsewhere and think about other things. Just ignore her words. But remember: such a tough attitude cannot be used often.” These words are from a series of cartoons which outline skills for children to fight against their mothers. The images have created heated debate among Chinese netizens(网民).
Regarded as “a book for children aged 6 to 12 who are always scolded by their parents”, the cartoons, drawn by two 10-year-old Beijing girls, list over 20 skills which children can use to deal with their mothers’ anger such as crying, pretending to be ashamed, fleeing into the toilet and pleasing her afterwards. Each skill is described with vivid pictures and humorous notes. The creativity of the young girls has amazed netizens, the Yangtse Evening Post reported on Thursday.
According to one of the girls’ mothers, her daughter once received a poor mark in an exam, and the mother blamed her and compared her performance with another classmate. The daughter’s feelings led to her creating the cartoons. The girl’s father, who first posted the pictures on his Sohu Microblog on Monday, said he hopes parents pay close attention to the pictures, allow children to feel free to develop their own characteristics and try not to criticize them so often.
“The cartoons, although an individual case, reflect a modern phenomenon and some of the problems within Chinese family education,” said Yu Qinfang, an expert on family education. According to a survey of 104 children and their parents, Yu discovered that as many as 51.9 percent of primary school students hate being urged to do things by their mothers.“Not giving children enough time and hurrying them to do things seems to be a very tiny detail within family life, but it is potentially a huge problem which can easily be ignored by parents. A mother’s blame may lead to negative feelings within her child’s heart,” Yu said. “Parents should learn to blame less and be more patient.”

【推荐3】Selecting what to wear can be a difficult problem, especially if you’re a fashion victim.
Trying to follow the latest styles involves regular visits to the shops and sometimes spending much money on expensive designer clothes.But when the fashion changes, these clothes had to stay in the back of cupboards gathering dust, or just get thrown away.
There are many stores that now offer cheap “fast fashion”—low-price items that imitate the styles of more expensive designer brands.
Environmentalists are angered by the amount of energy involved in making these clothes and that many of them are made from non-recyclable materials. This means that items are just burned or go into landfill.
Writing about this for the BBC, Eleanor Lawrie says that people in the UK are the worst in Europe for doing this—with a million tons of unwanted textiles a year being thrown away.
And she says, “on top of often poor labour conditions for garment workers, the fashion industry is responsible for 20%of the world’s waste water, and 10%of carbon emissions.”
This is something the fashion industry is becoming more aware of and has led to a new crop of biomaterials that replace wasteful textiles like cotton and leather.
Examples include Piňatex, a leather-like substance made from pineapple leaves. It’s been used in collections by Hugo Boss and H&M. And there’s mycelium, the root structure of mushrooms, that’s being used to create food, packaging and textiles. Cotton is a very resource-intense crop to grow. Eleanor Lawrie says, “about 15.000 litres of water are required to make one pair of 1eans.
So, buying organic cotton is a better choice. And there is also Tencel(天丝绒), also known as Lyocell(莱赛尔纤维绒), a natural product that’s now growing in popularity. It’s made by obtaining fibre from trees; its manufacture is thought to use 95%less water than cotton processing.
But creating sustainable(可持续的)textiles is only part of the battle-buying ethically(符合道德准则地), buying second hand and buying fewer clothes are the obvious environmentally friendly choices.
1. What does “fashion victim” mean according to the first paragraph?A.People who are fed up with fashion. | B.People who pursue fashion blindly. |
C.People who show no concern about fashion. | D.People who oppose fashion strongly. |

【推荐1】You feel happiest when you create a healthy balance between giving and receiving, If you give and give without making time to fill your own needs, then it’s likely you will burn out, or feel upset. When you take and take without giving anything back, you never feel fulfilled, so you are always searching for ways to fill the void in your life.
The way to create a healthy balance between giving and receiving is to know and then live by your values. I break values up into two groups which I call being and having values. Your being values are the character traits (痕迹,特征)of the ideal person you would like to be. I suggest to my clients that they choose three being values that they are willing to make a commitment (承诺) to live by, Examples of some being values are: kind, loving, generous, inspirational, peaceful, wise and even powerful, By acting on these values you give others through your actions and you inspire others by being a positive role model, Mastering being these character traits becomes your life purpose.
Your having values are the feelings you need to create in order to be happy. These could be companionship, achievement, support, being valued or financial security. They are what you receive. You take responsibility for filling your own needs by taking steps to create these feelings and conditions in your life.
When you make a commitment to live by your being values, it becomes easier to make conscious choices rather than reactionary ones. If your usual pattern is to talk about your problems, you could choose to think and act like a calm person. A calm person might go for a walk, have a deep thinking, or set a time limit before responding. If your usual pattern is to worry, you could choose to act like a responsible or wise person. In other words, you would act like the person you choose to be—this is the key to personal power.
When you choose to act on your values, you not only feel good about yourself, you strengthen your chosen beliefs. Over time acting in this way changes how you see the world, and in turn the way other people think of you.
1. The main purpose of this passage is to ______.A.persuade the readers to make a commitment |
B.explain to the readers what personal values are |
C.inform the readers how to be truly happy |
D.instruct the readers how to make wise choices |
A.a feeling of emptiness | B.an absence of one’s mind |
C.a break of consciousness | D.a state of confusion |
A.having values are better than being values |
B.a calm person does not choose to complain |
C.the way other people think of you decides who you are |
D.a responsible person does not care about financial security |
【推荐2】Courage is a highly admired virtue. When asked to describe courage, most people conjure up(脑中浮现)the image of an individual running into a burning building, or maybe a hero saving the world. But there's another form of bravery that's much more important because it comes up more often. It's called moral courage.
Moral courage is the ability that allows us to face our fears and to conquer our darkest fears. It's the ability to face the future without knowing what is certain. It's the ability to stand tall and confront those who oppose us, those who prevent us from realizing who we are and what we are. But most importantly, it's the ability to stand up for what's right, even though there are risks that stand in your way. Sara Anderson once said that “It takes great courage to faithfully follow what we know to be true.”
The potential of showing moral courage has the power of changing the world. It was because of the moral courage that Mahatma Gandhi was able to make India free from British rule. He fought bravely against them without the use of any weapon by presenting great moral courage. In this way, he also became a great example for the people of the whole world. It is not that we remember Gandhi because of his body or beauty. We remember him because of the great ideas and principles of his life.
Moral courage is essential not only for a noble life, but a happy one. Without moral courage, we have no control over our lives. Our fears destroy our spirit and make us trapped in depression. Mark Twain said, “Courage is not the absence of fear but the resistance of fear, the mastery of fear.” If our fears cause us to lose confidence in the power of virtue, we will lose something very precious.
People with moral courage rarely get medals, but it is the best marker of true character and a virtue others can be proud of. We must try to develop the power of moral courage that will surely help in ending injustice and wrong and grant us a better world.
1. What is the main function of paragraph 1?A.To make a comparison. | B.To propose a definition. |

【推荐3】The US Institute of Electrical and Electronics Engineers (IEEE) recently asked scientists, lawyers, social scientists and other experts to consider some of these ethical dimension. To give two examples: on privacy, as we let more listening devices into our homes, how do we prevent the data they collect falling into the wrong hands through hacking (黑客) or simply being sold between companies without us receiving any money? Another example: mixed reality, including virtual reality, will become pervasive in the next few years. As we move from headsets to what the IEEE committee describes as “more delicate sensory enhancements” we will use technology to live in an illusory world in many aspects of our lives. How do we balance the rights of the individual, control over our virtual identity, and the need to live and interact on a face-to-face basis while being empowered to live rich lives in mixed reality?
There is, of course, always a tension between innovation and regulation. But it can often seem that giant steps are taken in technology with minimal public discussion. Take the self-driving car: although it may be safer than human drivers and is likely to save more than a million lives a year worldwide, it will also take jobs from drivers, traffic police, sign-makers, car-repair companies, carmakers and more. Is this a bargain we want to make? In taking that decision, have we given thought to a car that knows everywhere we go, decides routes, perhaps, based on paid advertisement from shops along the way—and listens and sees everything we do on board? What will happen to that data and can it be kept safe?
Additionally, while some worry about the uncommon “trolley problem” of whom the car should choose to hit in a strange accident—an old lady or a mother and baby—perhaps the more frequent issue will be how we find out what the algorithm (运算程序) was thinking at the time of an accident, because AIs (Artificial Intelligence) are self-learning and devise their own strategies.
Similar concerns are emerging over the internet of things. Robot vacuum-cleaners already plot cleaning cycles using computer-aided vision that, for some models, is relayed to their manufacturers. As more things at home become connected, they will be hackable and the data they collect saleable.
It’s time for some messy, democratic discussions about the future of AI.

【推荐1】History is full of tales of great ideas taking shape in sleeping minds; Paul McCartney said that he awoke with the tune of Yesterday in his head, and Robert Louis Stevenson said that the idea for The Strange Case of Dr Jekyll and Mr Hyde came to him in a dream.
Scientists believe that the mind at night puts together bits of information in creative ways. Throughout the day your brain rarely gets a chance to stop and think. It constantly responds to a stream of challenges, from writing a report for a work deadline to remembering where you left your car keys and figuring out what to buy for dinner.
“Think of your brain like a web," says Russell Foster, Professor of Neuroscience at Oxford University. "During the day the web is very tight, so you can only put information in a certain number of places. During sleep the web expands, and with the luxury of time, those bits of information can be put into lots of different places and make new associations."
He adds that this process may help to foster the formation of new ideas. "This bringing together of seemingly unrelated bits of information is vital to helping the brain think itself out of problems,” says Russell Foster.
"Sleep seems to allow your mind to make non-obvious connections. It puts all the information from the day into a big biological theatre and forces the mind to speak to people at the back of the theatre, who you may not think you have any connection with. This is the basis of creativity connecting ideas, events and memories that wouldn't normally fit together.
By placing volunteers into brain scanners and sending them to sleep, scientists have seen that the areas associated with emotion go into overdrive, especially while dreaming, while the areas that are responsible for logic (逻辑)are switched off. This not only explains why dreams are unbelievably random-you can be talking to a colleague one minute and the next minute sitting in your old school classroom dressed in your nightclothes—but also explains how the brain can put together different information.

【推荐2】The majority of people on this planet live through ego(自我意识). They feel that they are themselves special, apart from the crowd in some way. Also, they aren't willing to acknowledge other people's special-ness, and feel that they are threatened by the people who are different from them.
Besides, there are many different 'exclusive clubs' which people join under certain conditions, like Colour of skin clubs, Sports clubs, and so on. What many people fail to acknowledge, however, is that there is in fact only one club The Human Being club.
Our diversity is what makes life interesting. I love watching people who dance or create music beautifully, draw out emotions through their acting skills, or are accomplished athletes. I also understand myself well enough to know that I don't have enough passion for any of these things to make the sacrifices necessary to come close to their level of excellence.
I believe that it is human nature to communicate and cooperate with people who are like us, but what a lot of people see as 'like us' is narrowed down to very superficial(表面) characteristics. I remember my Jamaican friend's sister being most put out. She had been the only black woman in her company and then another black woman was employed. They were automatically put to work together because they were both black and obviously had a lot in common - so thought the employer! The truth was that they had nothing in common, didn't come from the same country and actively disliked each other. It's always a mistake to assume anything on a purely superficial basis.
I have many friends who are members of a variety of the above mentioned clubs and each one of them has taught me so much about different cultures and life styles, and has enriched my life in the process. I encourage anyone to strike up a conversation with someone who doesn't look like them - you might be surprised at exactly how much you have in common.

It's no surprise that poor sleep habits may negatively impact academic performance. And dozens of studies have linked an increase in nightly sleep to better cognition and alertness. The new research, however, goes a step further, quantifying the impact of erratic or inadequate sleep on grades. These findings are more convincing than saying that if you get more sleep, you'll feel better," says Jennifer Cousins, a lead researcher of the study.
The study involved data from 56 adolescents (34 female) between the ages of 14 and 18 years. They were asked to fill out sleep diaries for one week and wear a special activity monitor on their wrists, which recorded when the students were asleep or awake. Overall, teens with poor sleep habits received lower grades than students who stuck with a more regular sleep routine.
Interestingly, Cousins also found that different sleep habits had different effects on the students' school performance:those who woke up more often during the night did worse in math, for example, while those who slept peacefully through the night tended to get better grades in English.
These findings bring up new questions about teasing out(探讨)the details of what is important about sleep that impacts learning," says Cousins. "Does more sleep improve our ability to deal with abstract concepts found in math, or does sleep quality increase creativity? We don't know the answers, and don't want to draw those conclusions yet. But this helps us understand more about how sleep helps the things we do in daily life. "
Authors of the study point out that the results provide overwhelming evidence of the importance of sleep during a period of development that is critical for adolescents and recommend sleep education as a prevention tool to help increase awareness of the importance of sleep and of the negative consequences of poor sleep.
