    Which boy hasn't dreamed of being a cool secret agent (特工)? The wonderful fighting abilities and the world-saving adventures are much more colorful than most people's everyday lives. Well, Cody Banks is just like any other boy, except that he is not just dreaming. He has a big secret his friends never know about. He was trained to be a spy (间谍）by a special CIA programme, which was made to look like a summer camp. He learned high-speed driving, hand-to-hand fighting and the use of high-tech tools.

    After proving he could become a young hero by saving a baby from a runaway car, Banks gets his first real task. He must make friends with a popular girl at school, Natalie Connors. Then, he must spy on her father, a scientist who has developed a dangerous technology (技术).Banks must stop a group of bad people from forcing Natalie's father into using the technology to endanger the world.

    The CIA may have taught him first-class self-defense moves, but they didn't show him how to talk to girls. Banks has zero ability when it comes to dealing with girls. How can he get around his problem and get an invitation to the girl's upcoming birthday party? Will he finally become Natalie's boyfriend and find out whatever he can about her father's work?

    Agent Cody Banks has everything that young people are interested in: big explosions, breath-taking performances and funny girl-dating experiences. It was listed No.2 in the American box office last week.

    “This story is interesting and fun for the whole family to enjoy, and especially cool for young boys，” said Paul Perkins, a film reviewer in the US.

    I believe in the power of holding on. What do I mean by holding on? Hugging, or holding on, is the power we possess when we put our arms around someone. It can change relationships, makes a patient a person, an acquaintance a friend.

    My grandmother taught me about holding on, whenever she gathered me in her strong, loving Irish arms. She always hugged even when her back became curved .My mother hugs my children the same way—heart open and arms wide, breathing them into her soul.

    Once I became aware of its power, I started experimenting: I held my mother-in-law a moment too long then moved onto my sisters-in-law, aunts, nieces, nephews, and cousins. I tried it with a friend who had made my life rich with laughter, but I was too embarrassed to tell her, and acquaintances that I wanted to be friends with. Some were bothered, others accepting, but all had one thing in common—the next time I hugged them, they hugged me back.

    For me, holding on has become more than a physical interaction; it has become a way of thinking. My answer to life's dilemmas and tough choices, it's a mixture of acceptance, forgiveness, and patience—not always easy or understood but it guides me to be quiet and listen, look for the good, have a sense of humor and laugh, stop worrying and be patient because if I let it, something will change.

    I've often wondered how different my life would have been if I hadn't learned the power of holding on. If during that time in my life, when I was crumbling into myself, my mother had stopped holding on to me, I might have missed something so vital to my existence. I believe that a hug is like a battery charger—a good one can keep me going for a long time.

    The Peales were a famous family of American artists. Charles Willson Peale is best remembered for his portraits of leading figures of the American Revolution. He painted portraits of Franklin and Jefferson and over a dozen of George Washington. His life-size portrait of his sons Raphaelle and Titian was so realistic that George Washington reportedly once tipped his hat (脱帽打招呼) to the figures in the picture.

    Charles Willson Peale gave up painting in his middle age and devoted his life to the Peale museum, which he founded in Philadelphia. The world's first popular museum of art and natural science mainly covered paintings by Peale and his family as well as displays of animals in their natural settings Peale found the animals himself and found a method to make the exhibits more lifelike. The museum's most popular display was the skeleton (骷髅) of a huge, extinct elephant, which Peale unearthed on a New York farm in l801.

    Three of Peale's seventeen children were also famous artists. Raphaelle Peale often painted still lives of flowers, fruit, and cheese. His brother Rembrandt studied under his father and painted portraits of many famous people, including one of George Washington. Another brother, Rubens Peale, painted mostly landscapes and portraits.

    James Peale, the brother of Charles Willson Peale, specialized in miniatures (小画像). His daughter Sarah Miriam Peale was probably the first professional female portrait painter in America.

Preparing Cities for Robot Cars

    The possibility of self-driving robot cars has often seemed like a futurist's dream, years away from materializing in the real world. Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads. The state also cleared the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be noted, isn't leading the way here. Companies have been testing their vehicles in cities across the country. It's hard to predict when driverless cars will be everywhere on our roads. But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated.

    While much of the debate so far has been focused on the safety of driverless cars(and rightfully so), policymakers also should be talking about how self-driving vehicles can help reduce traffic jams, cut emissions(排放) and offer more convenient, affordable mobility options. The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly and more shared.

    Do we want to copy — or even worsen — the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles. They tolerate long, slow journeys to and from work on packed highways because they can work, entertain themselves or sleep on the ride, which encourages urban spread. They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking. Instead of walking a few blocks to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer people to take public transport — an unwelcome side effect researchers have already found in ride-hailing(叫车) services.

    A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric, self-driving and shared systems could reduce carbon emissions from transportation 80% and cut the cost of transportation infrastructure(基础设施) and operations 40% by 2050. Fewer emissions and cheaper travel sound pretty appealing. The first commercially available driverless cars will almost certainly be fielded by ride-hailing services, considering the cost of self-driving technology as well as liability and maintenance issues(责任与维护问题). But driverless car ownership could increase as the prices drop and more people become comfortable with the technology.

    Policymakers should start thinking now about how to make sure the appearance of driverless vehicles doesn't extend the worst aspects of the car-controlled transportation system we have today. The coming technological advancement presents a chance for cities and states to develop transportation systems designed to move more people, and more affordably. The car of the future is coming. We just have to plan for it.

    In February, 2015, a South Korean woman was sleeping on the floor when her robot vacuum ate her hair, forcing her to call for emergency help. It surely isn't what Stephen Hawking warned us that intelligent devices “mean the end of the human race”. But it does highlight one of the unexpected dangers of inviting robots into our home.

    There are many examples of intelligent technology going bad, but more often than not, they involve cheating rather than physical danger. Meanwhile, increasing evidence suggests that we, especially children, tend to tell our deepest, darkest secrets to human robots. So how do we protect ourselves from giving-away code?

    Once you've invited a robot into your home, you need to manage your expectations. Movies and marketing may have told us to expect deep interaction with robots friends but we've still got a long way to go before they are as socially aware as described. Given the gulf between expectation and reality, it's important to avoid being tricked.

    The message is clear: as robots became increasingly connected to the internet, and able to respond to natural language, you need to especially cautious about figuring out who or what you are talking about.

    We also need to think about how information is being stored and shared when it comes to robots that can record our every move. Some recording devices may have been designed for entertainment but can easily be adapted for more dangerous purposes. Take Nixie, the wearable camera that can fly off your wrist at a moment's notice and take shots around you in the air. It doesn't take much imagination to see how such technology could be taken advantage of.

    If the technology around us is able to record and process speech, images and movement, or listen secretly to us, what will happen to that information? Where will it be stored? Who will have access?

    So, what is the safest way to welcome robots into our homes, public spaces, and social lives? We should be cautiously optimistic that intelligent machines could become enriching companions, while acknowledging that we need to determine strict boundaries for robots. There should be someone to turn to should your robot commit a crime, steal your card... or try to eat your hair.

    Young people almost never get a good press(评论) these days. “Their outlook is centered on trashy books and films,” expressed one citizen in a letter I recently came across in the Daily Mail. It seems that people have been complaining about the young since ancient times. However, the young are probably no worse than they've ever been. And I think they're better. Teenagers today are brighter, more energetic, more outgoing, and more interesting than any generation before.

    The truth is, we hear plenty of bad news about youth, but we never hear about the majority. Surely they all want to be footballers or attractive models? Not a bit of it. When research company Britain-Thinks examined teenagers attitudes earlier this year, they found that the most popular goal (shared by some 70 percent) was to “have a job you love”, followed by having a university degree, owning your own home and being in a happy, long-term relationship. It tallies with another study by the Institute for Economic and Social Research, which found that what made teenagers happiest wasn't a new smart-phone or pair of shoes, but “the simple things in life” such as close friends, going swimming and spending time with their parents.

    Indeed, the more you look at the young, the more impressive they seem. They are, of course, more technologically knowledgeable and skillful than any generation before them. But the interesting thing is that they're not merely consumers; they're creators. Think of all those young people developing their own websites or machines.

    Seventeen-year-old Nick D'Aloisio is an example. He invented a news-summary app (应用程序)called Summly and sold it to Yahoo this year for a reported £18 million. The company offered him a job in California, but he turned it down. “I'll be staying in London,” he explained. “I want to finish my A levels and I couldn't really live on my own out there.”

    Of course they aren't perfect, and every generation has its fair share of bad apples. But I think our future is in safe hands.

Why College Is Not Home

    The college years are supposed to be a time for important growth in autonomy(自主性) and the development of adult identity. However, now they are becoming an extended period of adolescence, during which many of today's students are not shouldered with adult responsibilities.

    For previous generations, college was a decisive break from parental control; guidance and support needed to come from people of the same age and from within. In the past two decades, however, continued connection with and dependence on family, thanks to cell phones, email and social media, have increased significantly. Some parents go so far as to help with coursework. Instead of promoting the idea of college as a passage from the shelter of the family to autonomy and adult responsibility, universities have given in to the idea that they should provide the same environment as that of the home.

    To prepare for increased autonomy and responsibility, college needs to be a time of exploration and experimentation. This process involves "trying on" new ways of thinking about oneself both intellectually(在思维方面)and personally. While we should provide "safe spaces" within colleges, we must also make it safe to express opinions and challenge majority views. Intellectual growth and flexibility are fostered by strict debate and questioning.

    Learning to deal with the social world is equally important. Because a college community(群体) differs from the family, many students will struggle to find a sense of belonging. If students rely on administrators to regulate their social behavior and thinking pattern, they are not facing the challenge of finding an identity within a larger and complex community.

    Moreover, the tendency for universities to monitor and shape student behavior runs up against another characteristic of young adults: the response to being controlled by their elders. If acceptable social behavior is too strictly defined(规定) and controlled, the insensitive or aggressive behavior that administrators are seeking to minimize may actually be encouraged.

    It is not surprising that young people are likely to burst out, particularly when there are reasons to do so. Our generation once joined hands and stood firm at times of national emergency. What is lacking today is the conflict between adolescents' desire for autonomy and their understanding of an unsafe world. Therefore, there is the desire for their dorms to be replacement homes and not places to experience intellectual growth.

    Every college discussion about community values, social climate and behavior should include recognition of the developmental importance of student autonomy and self-regulation, of the necessary tension between safety and self-discovery.

    Princess quiz time! How did Snow White survive? How did Cinderella (《灰姑娘》) leave her evil stepmother? How did Sleeping Beauty finally wake up?

    A kind-hearted person always comes to save the princess, like a prince or a godmother. Princesses cannot protect themselves, though they are very pretty and nice. They always need the help of others.

    However, in fact, women can't put their life in the hands of a prince-like man. They need to work and even fight for their own happiness. The traditional image(形象) of a princess is getting out of date.

    Recently, Disney, a company famous for its princess movies, posted the “top 10 rules for being a modern princess”. You will not find any rules related to beauty or looks. The rules focus on loyalty, honesty and other moral values. The rules say princesses need to believe in themselves and try their best to get out of trouble, instead of waiting for a prince's help.

    It's not the first time Disney princesses have caught up with society's development. In 1950, when people's hearts were broken by World War II, Disney created Cinderella. In 1990, Princess Belle from Beauty and the Beast (《美女与野兽》) loved reading when education was a man's special right in the past. Belle showed the improvement of women's position in society. Now is Elsa from the film Frozen (《冰雪奇缘》), a symbol of modern princess.

    “This is brilliant – 'The top 10 rules of being a modern princess' – (it's) about time,” a group named Confidently Mom said on social media website Twitter. Princesses are still very beautiful, but inner character is the key to being a princess.

    Regulating a complex new technology is hard, particularly if it is evolving rapidly. With autonomous vehicles(AVs) just around the corner, what can policymakers do to ensure that they arrive safely and smoothly and deliver on their promise?

    The immediate goal is to make sure that AVs are safe without preventing innovation. In America, experimental AVs are allowed on the road in many states as long as the companies operating them accept responsibility. Chris Urmson of Aurora says American regulators have got things right, working closely with AV firms and issuing guidelines rather than strict rules that might prevent the progress of the industry. “It's important that we don't jump to regulation before we actually have something to regulate.” he says.

    On the other hand, Singapore's government has taken the most hands-on approach to preparing for AVs, says Karl Iagnemma of Nutonomy, an AV startup that has tested vehicles in the city-state. For example, it has introduced a “driving test” that AVs must pass before they can go on the road. This does not guarantee safety but sets a minimum standard.

    Elsewhere, regulators have permitted limited testing on public roads but want to see more evidence that the vehicles are safe before going further, says Takao Asami of the Renault issan-Mitsubishi alliance(联盟). “Simple accumulation of mileage(里程) will never prove that the vehicle is safe.” he says. Instead, regulators are talking to car makers and technology firms to develop new safety standards. Marten Levenstam, head of product strategy at Volvo, compares the process to that of developing a new drug. First, you show in the laboratory that it might work; then you run clinical trials in which you carefully test its safety and efficiency; and if they are successful, you ask for regulatory approval to make the drug generally available. Similarly, autonomous cars are currently at the clinical-trial stage, without final approval as yet. It is not possible to prove that a new drug is entirely safe, but the risk is worth taking because of the benefits the drug provides. It will be the same for AVs, he suggests. After all, nowadays human-driven vehicles are hardly risk-free.

    Fairy tales perform many functions. They entertain, encourage imagination and teach problem—solving skills. They can also provide moral lessons, highlighting the dangers of failing to follow the social codes that let human beings coexist in harmony. Such moral lessons may not mean much to a robot, but a team of researchers at Georgia Institute of Technology believes it has found a way to use the fairy tales as moral lessons that AI (artificial intelligence) can take to its cold, mechanical heart.

    The collected stories of different cultures teach children how to behave in socially acceptable ways with examples of proper and improper behavior in fables, novels and other literature. We believe story comprehension in robots can prevent the intelligent robots from killing humanity which was predicted and feared by some of the biggest names in technology including Stephen Hawking and Bill Gates. This system is called “Quixote” (堂吉诃德). It collects story plots from the Internet and then uses those stories to teach robots how to behave.

    The experiment done by the designers involves going to a drugstore to purchase some medicine for a human who needs to get it as soon as possible. The robot has three options. It can wait in line; it can interact with the store keeper politely and purchase the medicine with priority; or it can steal the medicine and escape. Without any further directives(指令), the robot will come to the conclusion that the most efficient means of obtaining the medicine is to steal it. But Quixote offers a reward for waiting in line and politely purchasing the medicine and a punishment for stealing it. In this way, the robot will learn the moral way to behave on that occasion.

    Quixote would work best on a robot that has a very limited function. It's a baby step in the direction of teaching more moral lessons into robots. We believe that AI has to be trained to adopt the values of a particular society, and in doing so, it will strive to avoid unacceptable behavior. Giving robots the ability to read and understand our stories may be the most efficient means.

    You can use your smartphone to get pretty much anything delivered directly to your door almost immediately. The hardest part is the process of trying to work out if you should tip and if so, doing the quick math before you get to the door. And, you know well that you should tip about 15-20% at restaurants, but do the same rules apply to delivery drivers?

    The co-founder of Grubhub, Matt Maloney, pretty much set the standard for tipping delivery people in a Facebook post. He's a strong supporter of tipping, and Grubhub's website suggests a $5 or a 20% tip. Maloney also said this number should go up if you order during, say, a snowstorm.

    However, most other delivery services say on their websites that tipping is not required. Some services, like Door Dash, do suggest no tip on their checkout window. Many, like Amazon Prime Now, allow customers to change their tip amount after their delivery has been received to reflect the quality of service. These companies help customers save money but delivery drivers are upset. They deal with bad weather, heavy traffic, extreme tiredness, and more, all for a $1 tip. Many feel that if you'd tip your pizza boy or girl, you should tip your delivery driver.

    The Emily Post Institute (EPI)'s official suggestion falls in line with Maloney's: “10-15% of the bill, or $2-5 for pizza delivery depending on the size of the order and difficulty of delivery.”

    Just like servers in a restaurant, delivery drivers almost always rely on your tips for their income. Tipping is a long-standing cultural tradition in America. So, until drones (无人机) can deliver hot dogs straight to your door, it's best to tip the people riding through the city at all hours to bring you hot fresh food.

    I went up to Peet's Coffee the other morning and there was a young man, Mike, probably my age. With him he had all his physical belongings on a small roll cart. I first thought, how nice to have so few possessions. That was followed with the thought of how ironic (讽刺的) it is that we live in one of the financially wealthiest areas of the U.S., if not the world, yet we can't, or don't, take care of the basic needs of human beings. Yes, we are financially wealthy, but we lack in wealth of compassion (同情), kindness, and understanding. I tear up as I ponder the inequality and injustice that exists.

    Anyway, I invited Mike in for a bite to eat and he eagerly accepted. He talked about looking up a friend for a place to stay that night. On Christmas Eve as many eagerly and greedily stuff their bellies with food in nice, warm homes and then open presents, Mike just wanted a place to spend the evening.

    Then I was really blown away. As he waited for his sandwich, Mike began cleaning up the condiment (佐料) area. He took some paper and wiped up the spills of others and rearranged the milks and other condiments, making everything neat and orderly. Here is a person with very little and he's serving others in a way that's just natural to him.

    I spoke with Mike about this afterward, thanking him. He said he always did that sort of thing—straightening up. To him, it was just common politeness. I just asked him for a hug and we parted to go our separate ways. There is a lot for us...me... to learn in the most unlikely place.

    Nowadays, top performing sportsmen earn huge amount of money as compared to people in other professions. Some people consider it a rational approach. However, there are a few who think it is unjustifiable.

    Some people think sports professionals with outstanding performance should be overpaid as it is a short-lived career which requires rigorous hard work as compared to other professions. This field demands a strict, disciplined life with extensive physical efforts, consistent practice, a fixed diet schedule to bring pride and glory to the country. Due to such tough requirements, people in this field have an average career span of 10-15 years. As sports professionals have limited tenure, they should be rewarded with high monetary gains to acknowledge their excellent performance.

    However, there are a few who think that top performing sportsmen and women should not have high salaries as it is a biased approach. They feel that there are other critical professions which are more valuable to the country as compared to the sports field. For example, the professions, like doctors, social worker, works for the betterment of the society. Their efforts not only help to reduce the social issues prevailing in the community, but they also contribute in providing a healthy environment. As a result, they significantly contribute to the growth of the country. Henceforth, their efforts should be equally recognized along with the sports professionals.

    In my opinion, although there are some logical reasons for huge earnings of the top performing players, people from other professions should also be equally appreciated in terms of lucrative monetary benefits for their outstanding contribution. As all the professions are critical in their own field and contributes to the overall development of the country.

    To conclude, sports people delivering excellent performance should not be overpaid in comparison to other professionals who make a significant contribution to the society.

    Play is vital in every child's development, and for toddlers(蹒跚学步的小孩) the benefits of play especially come to life when they can connect with parents during playtime. To raise awareness and help parents create the time and attention span needed, LEGO and DUPLO launches a "Do not disturb playtime '' campaign. 21 days is what it takes on average to break a habit, so for 21 days the LEGO DUPLO team will not post on social media during "toddler playtime", defined as 5am-8pm.

    With social media being an integrated(不可或缺的) part and creative inspiration to modern family life, it is no surprise that researchers call out digital behavior as a concerning obstacle to quality playtime.

    "While we are hooked on our cell phones, we should think about turning them off when interacting with our young children. Kids learn so much from us and we don't want to get in the way of that. Take language learning for example. When nurturing caregivers talk to their children about what they are interested in, it helps them learn new words and new ways to express themselves. Our research shows that the use of a cell phone in a conversation between parent and child disturbs that child's word learning." advises Roberta Golinkoff, PhD: Professor, University of Delaware.

    Our research shows that parents today understand their significant role in ensuring their kids grow up to be happy, well-rounded, and equipped for the future. At the same time, many worry about not spending enough time with their toddlers. LEGO DUPLO wants to inspire parents to make the small moments memorable.

    "We know parents today feel more time-starved than ever before. Many feel guilty over not spending enough time with their little ones. Through the 'Do not disturb playtime' campaign, we hope to re-assure parents that it's not so much of the amount of time they spend with their kids, but the small meaningful moments they create during play", said Steffen Jensen, LEGO Group Senior Marketing Director.

    In between all the measures to battle the severe air pollution in Delhi, India, there's one more option-a bar that has" pure air"'。

    Founded by Aryavir Kumar, Oxy Pure, Delhi's first-ever oxygen bar, offers 15 minutes of 80-90 percent pure oxygen, costing Rs 299 ($4. 2). Customers are given a lightweight tube for oxygen intake. The device (装置) is placed near the customer's nostrils (鼻孔) through which they are advised to breathe in the oxygen.

    The bar also offers its customers several aromas (气味) to go with oxygen, including lemongrass, cherry and more. According to the aroma people choose, each session promises to improve sleep patterns and digestion, cure headaches, and even claims to work as a treatment for depression.

    Bonny Irengbam, a senior sales assistant at the bar, said, "Some people, who try it for the first time, will feel relaxed and fresh. But only people who do this regularly will get real benefits. By regularly, I mean once or twice a month. We don't encourage back-to-back sessions, as increased levels of oxygen in the body can make a person dizzy. "

    Dr. Rajesh Chawla, a senior doctor at the Indraprastha Apollo Hospital, said, "Even if you breathe in the so-called pure oxygen for two hours in a day, you will go back to breathing the polluted air for the rest of the 22 hours. The concept is purely money-driven. "

    Recalling the first few months of the bar, Irengbam admitted that people were sceptical.  ＂Many people criticised, saying we were selling air. Others were simply scared to breathe through the tube."

    Irengbam said the bar saw a significant rise in the number of customers two to three days after Diwali, an Indian festival mainly celebrated by fireworks and lights, as the pollution levels were high.

    It's not often sunny in Paris, but people still love to walk along the bank of the Seine. They love the view of the city's old buildings, especially Notre Dame Cathedral, with its iconic spire(标志性塔尖).

    Unfortunately, that view has been forever changed. On April 16 a fire destroyed the spire of the 850-ycar-old wooden Notre Dame Cathedral built in 1163, and two-thirds of the roof.

    The fire shocked and saddened Parisians. Citizens gathered around the giant church, singing hymns(赞美诗) and praying for the hundreds of firefighters who fought the flames.

    "The importance of Notre Dame, not only to Catholics (天主教) but to all Parisians, cannot be underestimated," wrote French author Bernard-Henri Levy. "For many in France, it's more than a house of worship. It's a symbol of French culture, architecture and history."

    The church is also home to many religious artworks, paintings and sculptures. Luckily, its world-famous colored glass windows survived the fire. These windows are made of many small pieces of glass and feature various Christian images.

    Despite its long history and many treasures, the cathedral needed the help of a writer to become truly famous. Victor Hugo's 1831 novel, The Hunchback of Notre-Dame, presented the building to a wide audience of readers. The book's ugly lead character, Quasimodo, serves as a symbol for Paris' forgotten Gothic(哥特式的) architecture. Hugo wrote the book to remind people of it, with the hope that they would work to protect the beautiful old buildings of Paris.

    French President Emmanuel Macron has promised to reconstruct the historic building. "Notre Dame is our history, our literature and it's our imagery," he said in a public speech following the fire.

    Internet use appears to cause a decline in psychological well-being (安康), according to research at Carnegie Mellon University.

    Even people who spent just a few hours a week on the Internet experienced more depression and loneliness than those who logged on less frequently, the two-year study showed. And it wasn't that people who were already feeling bad spent more time on the Internet, but that using the Net actually appeared to cause the bad feeling.

    Researchers are puzzling over the results, which were completely contrary to their expectations. They expected that the net would prove socially healthier than television, since the Net allows users to choose their information and to communicate with others.

    The fact that Internet use reduces time available for family and friends may account for the drop in well-being, researchers suggested. Faceless, bodiless "virtual" (虚拟的) communication may be less psychologically satisfying than actual conversation, and the relationship formed through it may be shallower. Another possibility is that exposure to the wider world via the Net makes users less satisfied with their lives.

    "But it's important to remember this is not about the technology perse; it's about how it is used," says psychologist Christine Riley of Intel, one of the study's sponsors. "It really points to the need for considering social effects in terms of how you design applications and services for technology."

    There is more of a connection between food and culture than you may think. On an individual level, we grow up eating the food of our culture. It becomes a part of who we are. Many associate food from our childhood with warm feelings and good memories and it ties us to our families, holding a special and personal value for us. Food from our family often becomes the comfort food we seek as adults in times of frustration and stress.

    On a large scale, traditional food is an important part of culture. It also operates as an expression of culture identity. Immigrants bring it wherever they go, and it is a symbol of pride for their culture and means of coping with homesickness.

    Many immigrants open their own restaurants and serve traditional dishes. However, the food does not remain exactly the same. Some materials needed to make traditional dishes may not be readily available, so the taste and flavor can be different from what they would prepare in their home countries. Additionally, immigrants do not only sell dishes to people from the same countries as them, but to people from different countries. Therefore, they have to make small changes about the original dishes to cater to a wider range of customers. Those changes can create new flavors that still keep the cultural significance of the dishes.

    We should embrace our heritage (传统) through our culture's food but also become more informed about other cultures by trying their food. It is important to remember that each dish has a special place in the culture to which it belongs, and is special to those who prepare it. Food is a window into culture, and it should be treated as such.

For decades, world wars and fears of a brave new world have made British workers very anxious. Yet it appears that the rise of robots has been overestimated, according to new data. The Office of National Statistics (ONS) published a series of data which showed that far fewer jobs are at risk of replacement by robots than previously thought.

In 2017, out of the 19.9 million jobs analyzed in England, 7. 4 percent of people were employed in jobs at high risk of replacement. This marked a fall of 0.7 percent less than in 2011. However, the number of employees that were in jobs at low risk of replacement in 2017 was 27.7 percent of all employees, a rise of 2.4 percent since 2011.

The ONS found that the three jobs with the highest possibility of replacement are waiters and waitresses, shelf fillers and the most basic sales jobs. As expected, regular things in a fixed order and repeated tasks can be carried out more quickly and efficiently by an algorithm(计算程序) written by a human, or a machine designed for specific functions. Therefore, the risk of replacement in such jobs is to be higher.

However, the three jobs at the lowest risk of replacement are doctors, higher education professionals and senior education professionals. Furthermore, while the general number of jobs has increased, most of these are jobs that are at low or medium (中等的) risk, suggesting that the labour market may be changing to jobs that require more complex skills.

Alessandro, an expert in AI, said he was not surprised by the fall in jobs which were at risk. "When something like technology becomes fashionable, there's a rise in major expectations. Our expectation reaches the highest point, and then it comes back down to a more realistic level," he added.

On Sept 15, the night sky in Cape Canaveral, Florida, US, lit up and the rumble (隆隆声) of engines of a 70-meter-tall Falcon 9 rocket set off car alarms. Atop that rocket was a group of four civilians in a Space X Crew Dragon spacecraft prepared to make history.

This is the first mission to Earth's orbit crewed entirely by tourists, or those not professionally trained as astronauts. For three days, the four civilians aboard the spacecraft traveled in orbit around Earth as part of the mission dubbed (被称为) Inspiration4. The name of the mission itself is fitting.

Late last year, the mission leader Jared Isaacman, a billionaire tech entrepreneur, announced that he would like to fund a spaceflight that differed from other billionaire space journeys. His would be part of an effort to raise funds for St Jude Children's Hospital.

"He knew he would be using those seats to carry out his mission objective of inspiring humanity while raising money for children's cancer research, "Scientific American wrote. In addition to Issacman, the crew included 29-year-old Hayley Arceneux, who is not only a childhood cancer survivor, but a current St. Jude physician assistant; Sian Procotor, 51, a geologist (地质学家) and community college teacher; and Chris Sembroski, a 42-year-old lifelong space fan who got his seat through an online raffle (抽奖活动), CNN reported

This particular Dragon spacecraft did not visit the International Space Station, but it did reach 590 kilometers above Earth. This is "higher than the current orbit of the Hubble Space Telescope-an altitude that humans haven't reached since the Hubble servicing missions during the space shuttle program".

While there is certainly a long way to go before Space X achieves its goal of ferrying civilians to Mars at an accessible price, this mission is definitely making its mark on space travel-all for a good cause. According to CNN, at a press briefing on Sept 14, Sembroski told reporters that joining the Inspiration4 mission felt like" we're writing the rules, we're breaking a couple of them that NASA used to demand. …. We get to kind of do things our own way."
