America’s Internet is faster than ever before, but people still complain about their Internet being too slow.

New York’s Attorney General’s office 1._______ an investigation in the fall into whether or not Verizon, Cablevision and Time Warner are delivering broadband that’s as fast as the providers 2._______ it is. Earlier this month, the office asked for the public’s help to measure their speed results, saying consumers 3._______ to get the speeds they were promised. “Too many of us may be paying for one thing, and getting another,” the Attorney General said.

If the investigation uncovers anything, it wouldn’t be the first time a telecom provider got into 4._______ over the broadband speeds it promised and delivered customers. Back in June, the Federal Communications Commission fined AT&T $100 million over 5._______ that the carrier secretly reduced wireless speeds after customers consumed a certain amount of 6._______.

Even when they stay on the right side of the law, Internet providers arouse customers’ anger over bandwidth speed and cost. Just this week, an investigation found that media and telecom giant Comcast is the most 7._______ provider. Over 10 months, Comcast received nearly 12,000 customer complaints, many 8._______ to its monthly data cap and overage (超过额度的)charges.

Some Americans are getting so 9._______ with Internet providers they’re just giving up. A recent study found that the number of Americans with high-speed Internet at home today 10._______ fell during the last two years, and 15% of people now consider themselves to be “cord-cutters.”

As if you needed another reason to hate the gym, it now turns out that exercise can exhaust not only your muscles, but also your eyes. Fear not, however, for coffee can stimulate them again. During 1._______ exercise, our muscles tire as they run out of fuel and build up waste products. Muscle performance can also be affected by a 2._______ called “central fatigue,” in which an imbalance in the body’s chemical messengers prevents the central nervous system from directing muscle movements 3._______. It was not known, however, whether central fatigue might also affect motor systems not directly 4._______ in the exercise itself, such as those that move the eyes. To find out, researchers gave 11 volunteer cyclists a carbohydrate (碳水化合物的)5._______ either with a moderate dose of caffeine (咖啡因), which is known to stimulate the central nervous system, or as a placebo (安慰剂)without, during 3 hours of 6._______. After exercising, the scientists tested the cyclists with eye-tracking cameras to see how well their brains could still 7._______ their visual system. The team found that exercise reduced the speed of rapid eye movements by about 8%, 8._______ their ability to capture new visual information. The caffeine, the equivalent of two strong cups of coffee, was 9._______ to reverse this effect, with some cyclists even displaying 10._______ eye movement speeds. So it might be a good idea to get someone else to drive you home after that marathon.

               Science of setbacks: How failure can improve career prospects

A) How do early career setbacks affect our long-term success? Failures can help us learn and overcome our fears. But disasters can still wound us. They can screw us up and set us back. Wouldn’t it be nice if there was genuine, scientifically documented truth to the expression “what doesn’t kill you makes you stronger”?

B) One way social scientists have probed the effects of career setbacks is to look at scientists of very similar qualifications. These scientists, for reasons that are mostly arbitrary, either just missed getting a research grant or just barely made it. In social sciences, this is known as examining “near misses” and “narrow wins” in areas where merit is subjective. That allows researchers to measure only the effects of being chosen or not. Studies in this area have found conflicting results. In the competitive game of biomedical science, research has been done on scientists who narrowly lost or won grant money. It suggests that narrow winners become even bigger winners down the line. In other words, the rich get richer.

C) A 2018 study published in the Proceedings of the National Academy of Sciences, for example, followed researchers in the Netherlands. Researchers concluded that those who just barely qualified for a grant were able to get twice as much money within the next eight years as those who just missed out. And the narrow winners were 50 percent more likely to be given a professorship.

D) Others in the US have found similar effects with National Institutes of Health early-career fellowships launching narrow winners far ahead of close losers. The phenomenon is often referred to as the Matthew effect, inspired by the Bible’s wisdom that to those who have, more will be given. There’s a good explanation for the phenomenon in the book The Formula: The Universal Laws of Success by Albert Laszlo Barabasi. According to Barabasi, it’s easier and less risky for those in positions of power to choose to hand awards and funding to those who’ve already been so recognized.

E)This is bad news for the losers. Small early career setbacks seem to have a disproportionate effect down the line.What didn’t kill them made them weaker. But other studies using the same technique have shown there’s sometimes no penalty to a near miss. Students who just miss getting into top high schools or universities do just as well later in life as those who just manage to get accepted. In this case, what didn’t kill them simply didn’t matter. So is there any evidence that setbacks might actually improve our career prospects? There is now.

F) In a study published in Nature Communications, Northwestern University sociologist Dashun Wang tracked more than 1,100 scientists who were on the border between getting a grant and missing out between 1990 and 2005. He followed various measures of performance over the next decade. These included how many papers they authored and how influential those papers were, as measured by the number of subsequent citations. As expected,there was a much higher rate of attrition(减员)among scientists who didn’t get grants. But among those who stayed on, the close losers performed even better than the narrow winners. To make sure this wasn’t by chance,Wang conducted additional tests using different performance measures. He examined how many times people were first authors on influential studies, and the like.

G) One straightforward reason close losers might outperform narrow winners is that the two groups have comparable ability. In Wang’s study, he selected the most determined, passionate scientists from the loser group and culled(剔除)what he deemed the weakest members of the winner group. Yet the persevering losers still came out on top. He thinks that being a close loser might give people a psychological boost, or the proverbial kick in the pants.

H) Utrecht University sociologist Arnout van de Rijt was the lead author on the 2018 paper showing the rich get richer. He said the new finding is apparently reasonable and worth some attention. His own work showed that although the narrow winners did get much more money in the near future, the actual performance of the close losers was just as good.

I) He said the people who should be paying regard to the Wang paper are the funding agents who distribute government grant money. After all, by continuing to pile riches on the narrow winners, the taxpayers are not getting the maximum bang for their buck if the close losers are performing just as well or even better. There’s a huge amount of time and effort that goes into the process of selecting who gets grants, he said, and the latest research shows that the scientific establishment is not very good at distributing money. “MIaybe we should spend less money trying to figure out who is better than who,” he said, suggesting that some more equal dividing up of money might be more productive and more efficient. Van de Rijt said he’s not convinced that losing out gives people a psychological boost. It may yet be a selection effect. Even though Wang tried to account for this by culling the weakest winners, it’s impossible to know which of the winners would have quit had they found themselves on the losing side.

J) For his part, Wang said that in his own experience, losing did light a motivating fire. He recalled a recent paper he submitted to a journal, which accepted it only to request extensive editing, and then reversed course and rejected it. He submitted the unedited version to a more respected journal and got accepted.

K) In sports and many areas of life, we think of failures as evidence of something we could have done better. We regard these disappointments as a fate we could have avoided with more careful preparation, different training, a better strategy, or more focus. And there it makes sense that failures show us the road to success. These papers deal with a kind of failure people have little control over-rejection. Others determine who wins and who loses. But at the very least, the research is starting to show that early setbacks don’t have to be fatal. They might even make us better at our jobs. Getting paid like a winner, though? That’s a different matter.

Educators and business leaders have more in common than it may seem. Teachers want to prepare students for a successful future. Technology companies have an interest in developing a workforce with the STEM (science, technology, engineering and math) skills needed to grow the company and advance the industry. How can they work together to achieve these goals? Play may be the answer.

Focusing on STEM skills is important, but the reality is that STEM skills are enhanced and more relevant when combined with traditional, hands-on creative activities. This combination is proving to be the best way to prepare today's children to be the makers and builders of tomorrow. That is why technology companies are partnering with educators to bring back good, old-fashioned play.

In fact many experts argue that the most important 21st-century skills aren't related to specific technologies or subject matter, but to creativity; skills like imagination, problem-finding and problem-¬solving, teamwork, optimism, patience and the ability to experiment and take risks. These are skills acquired when kids tinker (鼓捣小玩意). High-tech industries-such as NASA's Jet Propulsion Laboratory have found that their best overall problem solvers were master tinkerers in their youth.

There are cognitive (认知的) benefits of doing things the way we did as children一building something, tearing it down, then building it up again. Research shows that given 15 minutes of free play, four- and five-year-olds will spend a third of this time engaged in spatial, mathematical, and architectural activities. This type of play—especially with building blocks一helps children discover and develop key principles in math and geometry.

If play and building are critical to 21st-century skill development, that's really good news for two reasons:Children are born builders, makers, and creators, so fostering(培养)21st-century skills may be as simple as giving kids room to play, tinker and try things out, even as they grow older. Secondly, it doesn't take 21st-century technology to foster 21st-century skills. This is especially important for under-¬resourced schools and communities. Taking whatever materials are handy and tinkering with them is a simple way to engage those important "maker" skills. And anyone, anywhere, can do it.


1. What does the author say about educators?


Boredom has, paradoxically, become quite interesting to academics lately. In early May, London’s Boring Conference celebrated seven years of delighting in dullness. At this event, people flocked to talks about weather, traffic jams, and vending-machine sounds, among other sleep-inducing topics.

What, exactly, is everybody studying? One widely accepted psychological definition of boredom is “the distasteful experience of wanting, but being unable, to engage in satisfying activity.” But how can you quantify a person’s boredom level and compare it with someone else’s?

In 1986, psychologists introduced the Boredom Proneness Scale, designed to individual’s overall tendency to feel bored. By contrast, the Multidimensional State Boredom Scale, developed in 2008, measures a person’s feelings of boredom in a given situation.

Boredom has been linked to behavior issues including inattentive driving, mindless snacking, excessive drinking, and addictive gambling. In fact, many of us would choose pain over boredom.

One team of psychologists discovered that two-thirds of men and a quarter of women would rather self-administer electric shocks than sit alone with their thoughts for 15 minutes. Researching this phenomenon, another team asked volunteers to watch boring, sad, or neutral films, during which they could self-administer electric shocks. The bored volunteers shocked themselves more and harder than the sad or neutral ones did.

But boredom isn’t all bad. By encouraging self-reflection and daydreaming, it can spur activity. An early study gave participants abundant time to complete problem-solving and word-association exercises. Once all the obvious answers were exhausted, participants gave more and more inventive answers to combat boredom. A British study took these findings one step further, asking subjects to complete a creative challenge (coming up with a list of alternative uses for a household item). One group of subjects did a boring activity first, while the others went straight to the creative task. Those whose boredom pumps had been primed were more productive.

In our always-connected world, boredom may be a hard-to-define state, but it is a fertile one. Watch paint dry or water boil, or at least put away your smartphone for a while, and you might unlock your next big idea.
