The Olympic Games are well known and always receive the world’s attention, but there has been another little-known Olympic event in the UK for hundreds of years. And it’s an event which some say helped start the Olympic movement in this country. The Cotswold Olimpicks take place every year on a Friday in spring. They are held in a village in England known as the Cotswolds. It isn’t clear when the first event took place but some say it was as early as 1612.
The Cotswold Olimpicks were the idea of a lawyer called Robert Dover but no one knows exactly why he organized the games. Some people say he wanted to encourage people to support their king and country. Another explanation is that Dover was keen (渴望的) to bring people together, in particular the rich and poor from the local community. Whatever the reason was, the early games quickly became popular. People competed in familiar activities such as horse-racing running, jumping, and wrestling; famous people of the time attended them and poets wrote about the celebrations. It is even said that Shakespeare mentioned the Cotswold Olimpicks in The Merry Wives of Windsor, though the play may have been written some time before the first games.
As the Cotswold Olimpicks grew in popularity, a group of people known as the Puritans (清教徒) started to object to them for religious reasons, saying they encouraged bad behaviour. The games came to an end at the start of the English Civil War but in 1660 they were re-introduced. Over time they became more and more popular and there are records of 30,000 people attending in one year. However, the games also attracted people who were more interested in the celebrations than the sporting events. Finally, they came to an end once again in 1852. However, this was not the end of the Cotswold Olimpicks. They were re-introduced again in 1966 and have since been recognized by the British Olympic Committee. Out of respect to their history, the modern games are watched over by a man dressed as Sir Robert Dover, riding on horseback an accompanied by a representative of King James I, Unlike the real Olympic Games, the Cotswold Olimpicks have only about two hours and they are followed by celebrations in the village.

Shooting down an ice-covered track, a bobsled(大雪橇)can go faster than 80 miles an hour, and riders can feel force five times stronger than the pull of gravity. A race can be won or lost by one hundredth of a second. How do bobsleds go faster than cars on a highway? The answer is a combination of athletics and science.
At the start of a race, the crew push their sled, building up speed before they jump in for the ride. For months before the race, the crew have built up power in their legs. The push is the crew's only chance to add speed. All other work goes into keeping friction and drag(摩擦力和阻力)from slowing the sled down.
The design of the sled's runners(滑板)reduces their friction with the ice. The friction of a moving runner melts a little ice right under the runner, and the runner rides on that thin layer of water. The runners are rounded on the bottom. Runners that are too flat may not melt enough ice for fast ride. Runners that are too round may become too warm, softening the ice and slowing the sled down. No amount of rounding is perfect for all races because the hardness of the ice depends on the weather on race day.
Bobsleds used to be open. The riders did not sit inside a hull(外壳). As the crew sped down the track,the air would create drag. Today, a sled's hull reduces drag by splitting the air in front of the sled and making it flow smoothly along the slides. As with the runners,strict rules apply to the hull. For example,no team may add any part that would create helpful air currents.
Reducing friction and drag creates another challenge: high speeds. “The faster the sleds car travel on the run, the more thrilling the race,” one research team wrote. “But the track must not be too fast: he crew still need to be able to reach the bottom safely.”

【推荐3】The earliest cars made just for racing were built low to the ground and just wide enough for a single passenger, the driver. In the early 1900s, the drivers were the same people who invented and built the first passenger cars. For example, Henry Ford, founder of the Ford Motor Company, sometimes raced his cars. In 1906, the Indianapolis Motor Speedway was founded by Carl Fisher. On August 19, 1909, the first car race took place at the Indianapolis Motor Speedway. Twelve thousand were in attendance. In 1911, the first Indianapolis 500 was held there with 40 racers. Finishing in 6 hours and 42 minutes, first-place winner Ray Harroun clocked in at what seemed back in those days an unbelievably high average speed of 74.59 mph!
Over the years, as technology improved, these cars became lighter and faster. There are two kinds of open-wheel racecars, IndyCars and Formula One. IndyCars are almost exactly identical(完全相同的) to each other, so the race is a test of driving skills around a street, or race course, mostly in the U.S.; Formula One cars are customized(定做的) and raced on road courses around the world. Unlike the kind of car your family drives, neither IndyCars or F1 cars have doors, and their wheels are on the outside of the car’s body.
In 1936, Louis Meyer asked for a bottle of buttermilk after he became the first three-time Indy 500 winner, which led to the tradition of winners drinking a bottle of milk on Victory Lane(车道).
The Indy 500 has grown into one of the most anticipated(期待的) international racing events of the year, with hundreds of thousands of fans flooding into the stands each May. In 2011, it celebrated its 100th event---and tickets sold out for the first time ever.

【推荐1】The direct ray of the sun touches the equator and strikes northward toward the Tropic of Cancer (北回归线). In the Southern hemisphere winter has begun, and it is summer north of the equator. The sea and air grow warmer; the polar air of winter begins its gradual retreat. The northward shift of the sun also brings the season of tropical cyclones to the northern hemisphere, a season that is ending for the Pacific and India Oceans south of the equator. Along our coasts and those of Asia, it is time to look seaward, to guard against the season’s storms. Over the Pacific, the tropical cyclone season is never quite over, but varies in intensity. Every year, conditions east of the Philippines send a score of violent storms howling toward Asia, but it is worst from June through October. Southwest of Mexico, a few Pacific hurricanes will grow during spring and summer, but most will die at sea or perish over the desert or the lower California coast as violent storms.
Along our Atlantic and Gulf coasts, the hurricane season is from June to November. In an average year, there are fewer than ten tropical cyclones and six of them will develop into hurricanes. These will kill 50 to 100 persons between Texas and Maine and cause property damage of more than $100 million. If the year is worse than average, we will suffer several hundred deaths, and property damage will run to billions of dollars. Tornadoes, floods, and severe storms are in season elsewhere on the continent. Now, to these destructive forces must be added the hazard of the hurricane. From the National Hurricane Center in Miami, a radar fence reaches westward to Texas and northward to New England. It provides a 200-mile look into offshore disturbances. In Maryland, the giant computers of the National Meteorological Center digest the myriad bits of data—atmospheric pressure, temperature, humidity, surface winds, and winds aloft—received from weather stations and ships monitoring the atmospheric setting each hour, every day. Cloud photographs from spacecraft orbiting the earth are received in Maryland and are studied for the telltale spiral(旋涡) on the warming sea. The crew of United States aircraft over the Gulf of Mexico, Caribbean, and Atlantic watch the sky and wait for the storm that will bear a person’s name. The machinery of early warning vibrates with new urgency as the season of great storms begins.

【推荐2】Rachel Carson was a scientist by profession, but the lines from the open chapter of her 1962 book Silent Spring. “A Fable for Tomorrow”, show her talent as a writer. By imagining a world without birds, she aimed to alert (使警惕) not only the scientific community but also the general public to the damaging effects of human activity on natural ecosystem-----in particular, to the harmful use of pesticides (杀虫剂), such as DDT. She believed that the chemical industry was knowingly causing harm to plants, animals and even humans, and wished to see pesticides used in a more responsible, limited and carefully monitored way.
Carson urged people to make themselves aware of the facts and do something about the situation. Silent Spring contains a lot of scientific research and case studies. The book details the programme of removing gypsy moth, which killed birds, in addition to killing gypsy moths. Another case study was the fire-ant programme that killed cows, but not fire ants. The book also gives dozens of other examples of removal programmes that did nothing to reduce the problems they were originally designed to solve. The 50 or so pages at the end of the book list Carson’s source, showing how thorough and precise she was as a scientist.
Silent Spring was not, however, received positively by everyone. Though Carson’s research was strong and was supported by most scientists who reviewed her book, the book quickly became a target for critics in the pesticide industry. They said that Carson did not understand the science behind her arguments because she was a marine biologist rather than a chemist. Some also said that her work was more emotional than scientific.
These were attempts to damage Carson’s reputation (名声) and stop her from influencing public policy, but she remained determined to stand by her research. Carson appeared in public and on television to defend her claims----and today, more than 50 years after it was published, the voice of Silent Spring is still ringing loud and clear.

【推荐3】You’ve probably already heard about AI-powered cameras that can recognize people just by analyzing their facial features, but what if there was a way for artificial intelligence to figure out what you look like just by the sound of your voice and without comparing your voice to a database? That’s exactly what a team of scientists at MIT has been working on, and the results of their work are impressive. While their neural network, named Speech2Face, can’t yet figure out the exact facial features of a human just by their voice, it certainly gets plenty of details right.
Speech2Face is trained in the training data, which is a collection of educational videos from YouTube. “Our model is designed to reveal statistical connections that exist between facial features and voices of speakers in the training data,” the creators of Speech2Face said. However, the data does not represent equally the entire world population. Therefore, the model- -as is the case with any machine learning model- is affected by this uneven distribution of data.
You can tell a lot about a person from the way they speak alone. For example, you can most likely tell if someone is male or female, or if they are young or old, but Speech2Face goes beyond that. It can determine fairly accurately the shape of someone’ s nose, cheekbones or jaw from their voice alone, because the way the nose and other bones in our faces are structured determines the way we sound.
The racial characteristic is also one of the things Speech2Face can figure out with accuracy from listening to someone’s voice for just a few milliseconds, as people who come from the same groups tend to have similar qualities or features. The AI takes a variety of factors into account, and it sometimes produces impressive results, but it’s still a work in progress.

【推荐1】When people learn to play video games, they are learning a new literacy. Of course, this is not the way the word “literacy” is normally used. Traditionally, people think of literacy as the ability to read and write. Why, then, should we think of literacy more broadly?
Nowadays, language is not the only important communication system. Images, graphs, diagrams and many other visual symbols are particularly significant. Thus, the idea of different types of “visual literacy” would seem to be an important one. For example, being able to read the images in advertising is one type of visual literacy.
Furthermore, very often today words and images of various sorts are juxtaposed in a variety of ways. In newspapers and magazines as well as in textbooks, images take up more and more of the space alongside words. In fact, in many modern high school and college textbooks, images not only take up more space, they now carry meanings that are independent of the words in the text. If you can’t read these images, you will not be able to understand their meanings from the words in the text as was more usual in the past.
Now there are different ways to read different types of texts. Literacy is multiple, then, in the sense that the legal literacy needed for reading law books is not the same as the literacy needed for reading physics texts or cartoon books. And we should not be too quick to dismiss the latter form of literacy. Many cartoon books are full of images that would make a modern literary critic’s heart beat fast and confuse any otherwise normal adult.
Once we see this multiplicity of literacy, we realize that when we think about reading and writing, we have to think beyond print. Reading and writing in any field, whether it is law, rap songs, academic essays or cartoon books, are not the only ways of decoding(解密) print. Video games are a new form of art. They will not replace books; they will sit beside them, interact with them, and change them and their role in society in various ways, as, indeed, they are already doing strongly with movies. We have no idea yet how people “read” video games, what meanings they make from them. Still less do we know how they will “read” them in the future.

【推荐2】Making employees feel happy and healthy at work is good for many businesses. But it isn’t always an easy thing. A study suggests that only 33% of the U. S. employees consider themselves fully engaged (投身于)in work, while 16% are greatly disengaged, and 51% are just showing up.
But there is an exception. When it comes to employee engagement, it seems that employees in small companies are doing better. According to the same research, the largest U. S. companies are at the lowest levels of engagement, while companies with fewer than 25 employees are at the highest. And in one recent report, 75% of small business workers surveyed said they were “very” or “extremely” satisfied with their role as a small company employee.
Unlike big companies, small companies are often short of resources but the employees can get more surprises there. Small companies offer excellent career opportunities to their employees. The bosses often know their staff very well and understand their personal needs. Employees of small companies are more likely to receive free meals, paid leave, and they can even bring their pets to work.
But of course ? there are many other draws in small businesses. One of the top draws is flexible scheduling (弹性工时). Another is being able to really see the fruits of one's labor. Besides, non-cash award is also a big draw. This could be something small that reflects employees’ interests and lifestyles.
While a parental leave might lead to some financial problems, small companies may do something to improve it. “It may be impossible for a five-person team to be reduced to four for six months,” writes Camillia Velasquez, head of HR management platform, Justworks. “But it could be possible to allow new parents to take on reduced hours in a work-from-home environment. ” This kind of method has been realized in some small companies.

【推荐3】Most online fraud(诈骗) involves identity theft Passwords help. But many can be guessed. Newer phones, tablets, laptops and desktop computers often have strengthened security with fingerprint and facial recognition. But these can be imitated. That is why a new approach, behavioural biometrics(行为生物识别) is gaining ground.
It relies on the wealth of measurements made by today’s devices. These include data from sensors that reveal how people hold their phones when using them, how they carry them and even the way they walk. Touchscreens, keyboards and mice can be monitored(监测) to show the distinctive ways in which someone’s fingers and hands move. These features can then be used to determine whether someone attempting to make a deal is likely to be the device’s habitual user.
“Behavioural biometrics make it possible to identify an individual’s unique motion fingerprint”, says John Whaley, head of Unifyid, a firm in Silicon Valley that is involved in the field. When coupled with information about a user’s finger pressure and speed on the touchscreen, as well as a device’s regular places of use—as revealed by its GPS unit—that user’s identity can be pretty well determined.
Used wisely, behavioural biometrics could be a great benefit. In fact, Unifyid and an unnamed car company are even developing a system that unlocks the doors of a vehicle once the pace of the driver, as measured by his phone, is recognized. Used unwisely, however, the system would become yet another electronic spy on people’s privacy, permitting complete strangers to monitor your every action, from the moment you reach for your phone in the morning, to when you throw it on the floor at night.

【推荐1】I have three kids and a great husband and I’m enjoying a career that I find challenging and fun. This feels like “Success” to the outside world. But there is still a voice in my heart asking if this is who I truly am. Only in silence do I hear the self and wonder who that person might be.
So I booked a trip to find out. I travelled, for the first time, without my husband or kids.I went to Iceland with a friend, who shares an appreciation for wilderness and silence.
For six days, we were immersed in wild, raw scenery and real weather—all kinds of weather. Climbing a mountain against rain and returning to a tent for a simple meal reminds you how little you actually need. And how strong it feels to be uncomfortable sometimes.
I found silence in Iceland,and time to consider the me outside of career and the me outside of kids as I shared stories with strangers.
When I stopped talking and just listened,I became more generous.I 1earned that choosing to be generous can create more space, more food and more warmth.
But I didn’t really gain any better appreciation of what I want from life or my job.I suspect the anxiety that drove me to seek silence in Iceland was losing sight of my ability to choose gratitude and joy,and to be present in the challenges I set in my career and my family.
I came home to noise,rush and love;with no less confusion on who I want to be.I know the answer isn’t waiting out there on the top of a mountain in Iceland. The answer is in front of me with every step on my own 1ife’s path, and in every choice I make.

You need only look at a professional cyclist to appreciate the potential effects of cycling on the body. But what about the mind? It’s a question that has long challenged anyone who has wondered how riding a bike can offer what feels close to a state of emptying your mind.
Dr. John Ratey thinks cycling increases “the chemistry in your brain that makes you feel calm,” but also that carrying out multiple operations while cycling can be an effective treatment, as shown in a German study involving 115 children, half of whom did activities such as cycling that involved complex movements, while the rest performed more straightforward exercises with the same aerobic (有氧的) demands. Both groups did better than they previously had in concentration tests, but the “complex” group did a lot better.
There have been other interesting findings too. In 2003, Dr. Jay Alberts rode a tandem bicycle, a bicycle built for two riders sitting one behind the other, across the American state of Ohio with a friend who has Parkinson’s (帕金森) disease, a condition affecting the nervous system. The idea was to raise awareness of the disease, but to the surprise of both riders, the patient showed significant improvements. Dr. Jay Alberts then scanned the brains of 26 Parkinson’s patients during and after an eight-week exercise programme using bikes. Half the patients were allowed to ride at their own paces, while the others were pushed harder. All patients improved, and the group which was pushed harder showed particularly significant increases in connectivity between areas of intelligence responsible for functions such as walking and picking things up.
We don’t know how this happens, but there is more evidence of the link between Parkinson’s and cycling. A video on the Internet shows a 58-year-old man with severe Parkinson’s. At first, we watch the patient trying to walk. He can barely stand and his hands shake uncontrollably. Then we see the man on a bicycle being supported by others. With a push, he’s off, cycling past cars with perfect balance. Doctors don’t fully understand this discrepancy either, but say that cycling may act as some sort of action that helped the patient’s brain.
The science of cycling is incomplete, but perhaps the most remarkable thing for the everyday rider is that it can require no conscious focus at all. The mindlessness of cycling can not only make us happier, but also leave room for other thoughts. On the seat of my bike, I’ve solved problems at work and made life decisions, as, I’m sure, have countless others.

【推荐3】The COVID-19 pandemic has spread far and wide. Because of this, countries around the world have carried out measures to help stop the virus in its tracks. As more people stay inside to stay safe, the outside world seems to have become much quieter. In fact, scientists have seen this change in their research.
Seismologists - scientists who study earthquakes - have heard a lot less seismic(地震的) noise recently.
Seismic noise is made from vibrations (continuous shaking movements) in the ground that are caused by things like ocean waves and human activity, such as construction work and traffic. This noise makes it difficult for scientists to pick up seismic activity that is made at the same frequency.
Thomas Lecocq, a scientist at the Royal Observatory of Belgium, located in Brussels, was the first to notice this phenomenon. According to Lecocq, the amount of seismic noise in Brussels has been reduced by about 30 to 50 percent since mid-March. Interestingly enough, this is around the same time Belgium started its measures. Because of this reduction in background noise, scientists like Lecocq have been able to pick up on smaller earthquakes that some seismic stations - like the one in Brussels - wouldn’t have been able to before.
This phenomenon isn’t unique to Brussels, though. Once Lecocq shared his findings online, seismologists from all over the world echoed similar findings. Celeste Labedz, a graduate student at the California Institute of Technology, mentioned in a tweet that Los Angeles also experienced less background noise. “The drop is seriously wild,” she wrote.
Researchers from the UK, France and New Zealand also noted a decrease in background noise since measures were put in place.
These global efforts to contain the COVID-19 virus have helped to shed light on seismic activity that may have gone unnoticed. It also shows that people are listening to health officials and following lockdown rules. “From the seismological point of view, we can motivate people to say, ‘You feel like you’re alone at home, but we can tell you that everyone is home. Everyone is respecting the rules,’” Lecocq told CNN.
