Standing desks have been praised for their positive effects on physical health, reducing sitting time and lowering certain health risks linked to a sedentary( 久坐的) lifestyle. But could standing desks have positive mental effects?
New research suggests that students may think best when they are on their feet. It offers some of the first evidence of mental benefits of standing desks in classrooms.
Testing was done on high school freshmen who used standing desks, evaluating them at the beginning and end of the school year. Dr. Ranjana Mehta, an assistant professor at the Texas A&M School of Public Health, led the experiments aiming to assess standing desks’ mental benefits.
Through computerized tests, students’ executive functions were evaluated. Executive functions are the cognitive skills used to analyze tasks and break them into steps, and are directly related to academic needs like time management, memorizing facts and solving multi-step problems. These functions are largely controlled by frontal(前额的) brain regions, so researchers used a portable brain-imaging device to examine any related changes.
“Test results indicated that continued use of standing desks was associated with significant improvements in executive functions and working memory abilities,” Mehta said. “Changes in corresponding brain activation patterns were also observed.”
“Interestingly, our research showed the use of standing desks improved mental function, which is consistent with results from previous studies on school-based exercise programs,” Mehta noted.
Policymakers, public health professionals and school administrators should consider the positive effects of standing desks and make some simple changes in classrooms that will have the potential to increase energy expenditure and develop cognitive skills. That would be a valuable contribution to the educational world.

Think of Spider-Man, Iron Man and Ant-Man. Think of Black Panther, the Mighty Thor and the X-Men. Think of the Incredible Hulk, the Fantastic Four and all the other superheroes that have stimulated the popular imagination. 1.. From a small office in Manhattan in the 1960s, he helped create a lineup of fictional heroes that have crossed from page to screen in a series of TV and movie adaptations and changed the face of popular culture.
For many, he was the face of Marvel, if not comic books in general, witnessing the company's rise to become an international media giant. As a writer, editor, publisher and Hollywood executive, he played a critical role in what comic fans call one of the medium's golden ages.
2.. Lee gave the heroes flaws and insecurities, as well as an awareness of trends, social causes and a sense of humor, trying to ''make them real flesh-and-blood characters with personality, '' he told The Washington Post in 1992. ''That's what any story should have, but comics didn't have it until that point. They were all cardboard figures. ''
3.. Iron Man, for example, could join forces with the Fantastic Four, and Captain America could find himself a wedding guest alongside Doctor Strange. Lee created a fictional universe for readers to explore — one that made readers buy multiple series to get the whole story.
''I used to think what I did was not very important, '' Lee told the Chicago Tribune in 2014. ''People are building bridges and participating in medical research, and here I was working on stories about fictional people who do crazy things and wear costumes. But I suppose I have come to realize that entertainment is not easily dismissed. ''
Stan Lee was as extraordinary as the characters he created, said Disney chairman and CEO Bob Iger. Indeed, Lee worked tirelessly his whole life creating great characters for the world to enjoy. 4.. His legacy will outlive us all.
A.He inspired our imagination and hoped we could use it to make the world a better place.
B.If all these entertainment products can be traced to one person, it would be Stan Lee, who died last November at the age of 95.
C.Lee also appeared in a number of Marvel movies, watering his lawn, delivering the mail, and so on.
D.In order to keep multiple stories going at the same time, Lee wove them together into a seamless(无缝的) fictional world.
E.Under Lee, Marvel transformed the comic book world by humanizing its characters.
F.Through the honesty of guys like Spider-Man, we learn about different aspects of human nature.
On Wednesday, two things happened. In Syria, 80 people were killed by government airstrikes. Meanwhile, in Florida, Elon Musk’s SpaceX successfully launched and fired a sports car into space. Guess which story has dominated mainstream news sites?
The launch of Musk’s Falcon Heavy rocket, the most powerful ever launched by a private company, went off successfully. Musk sent his cherry-red Tesla roadster running toward Mars, launching “a new space age”. The event attracted phenomenal publicity and made the rocket launch a masterstroke of advertising for Tesla.
Meanwhile, in Syria, where hundreds of thousands of refugees may be forced to return to unsafe homes, a UN human rights coordinator for Syria said despondently(沮丧地) that he was no longer sure why he bothers to videotape the effects of bombing, since nobody ever pays attention. He wondered what level of violence it would take to make the world care.
There is, perhaps, no better way to appreciate the tragedy of 21st-century global inequality than by watching a billionaire spend $90m launching a $100,000 car into space.
Musk said he wanted to participate in a space race because “races are exciting” and that while strapping his car to a rocket may be “silly and fun … silly and fun things are important”. Thus, anyone who mentions the huge waste the project involves, or the various social uses to which these resources could be put, can be dismissed as a killjoy.
But one doesn’t have to hate fun to question the justification for pursuing a costly new space race at exactly this moment. If we examine the situation honestly, it becomes hard to defend a project like this.
A mission to Mars does indeed sound exciting, but it’s important to have our priorities straight. First, perhaps we could make it so that a child no longer dies of malaria every two minutes. Or we could try to address the level of poverty in Alabama which has become so extreme that the UN investigator did not believe it could occur in a first-world country. Perhaps when violence, poverty and disease are solved, then we can head for the stars.
Many might think that what Elon Musk chooses to do with his billions is Elon Musk’s business alone. If he wanted to spend all his money on medicine for children, that would be nice, but if he’d like to spend it making big explosions and sending his convertible on a million-mile space voyage, that’s his right.
But Musk is only rich enough to afford these money-consuming projects because we have allowed social inequalities to arise in the first place. If wealth were actually distributed fairly in this country, nobody would be in a position to fund his own private space program.
Elon Musk is right: silly and fun things are important. But some of them are an indefensible waste of resources. While there are still humanitarian crises such as that in Syria, nobody can justify vast spending on rocketry experiments.

Learning how to cope with death has always been a central part of human existence. Even the Pixar movie Coco bases its story on the Mexican traditions of Dia de los Muertos. In this article, you will find out why and how Mexicans celebrate the Day of the Dead.
I once visited the Museum of Mummies in the Mexican city of Guanajuato with a Swedish friend. The mummies were displayed among fake cobwebs ( 蜘 蛛 网 ), and other cheap adornments (装饰物). Confronted with this seeming lack of respect for the dead, I explained to my shocked companion that Mexicans have a peculiarly different relationship with death to other cultures. As the Nobel Prize-winning Mexican writer Octavio Paz explained in his work:
“The Mexican ... is familiar with death, jokes about it, caresses it, sleeps with it, and celebrates it. True, there is as much fear in his attitude as in that of others, but at least death is not hidden away: he looks at it face to face, with impatience, disdain (鄙视) or irony.”
The celebration of the Day of the Dead — a week of festivities from 28 October to 2 November — is an essential part of this embracement of death that is particular to Mexican national identity. The popular belief is that the dead have divine permission to visit friends and relatives on earth and enjoy once again the pleasures of life. Therefore, Mexicans visit the graves of families and friends and adorn them with colorful flowers and offerings of food. The period is a joyous celebration of life, rather than a sober mourning of its passing.
The origins of the festival lie in the 16th-century fusion of the Aztecs’ belief in death as merely one part in the wider cycle of existence, their ritual venerations (仪式崇拜) and offerings to the goddess Mictecacihuatl (“Lady of the Dead”) for the deceased, and the Spanish conquerors’ desire to accommodate these festivities within the Catholic celebrations of All Saints’ Day and All Souls’ Day.
In a country as socially and geographically diverse as Mexico, there is significant regional variation in the nature of festivities: the southern state of Chiapas is far more likely to focus its efforts on processions ( 队 伍 ) and public commemorations( 纪 念 ) of death than the valley of
Mexico, where the decoration of altars ( 供 坛 ) in homes and tombs of the deceased is more popular. Urbanization, too, plays a large role in regional variations. For the south and rural areas the period holds far greater social and cultural significance than in the north and large cities; families and communities in rural areas will often spend large parts of the year preparing for the occasion.
1.Why does the author say “Mexicans have a peculiarly different relationship with death to other cultures?”
A.Because Mexicans always show their respect for death in the form of mummies.
B.Because Mexicans do not fear death or respect it.
C.Because adornments like flowers can be seen everywhere during the Day of the Dead.
D.Mexicans face death bravely rather than hide it away.

A.It was the Aztecs who determined how to celebrate the Day of the Dead.
B.The Aztecs believed death was part of the wider cycle of existence.
C.The Aztecs would give offerings to the goddess of death for their lost loved ones.
D.The Spanish conquerors wanted to fit the festivities into some of their Catholic celebrations.
3.Why do Mexicans visit the graves of families and friends and offer colorful flowers and food?
A.Because they can ask God to permit the dead to visit them in this way.
B.To celebrate the joy of new life in spring.
C.Because the dead will be permitted to visit their families and enjoy the pleasure of life again.
D.Because this is an essential part of embracement of death.
4.Which of the following explains the role that urbanization plays in the regional variations of celebrating the Day of the Dead?
A.People in the south and rural areas put more emphasis on the occasion.
B.People in the valleys usually decorate the alters in homes and the tombs of the dead.
C.People in the north and big cities spend large part of the year preparing for the celebration.
D.The southern states do not care about the decoration of alters at home.
A new phone app uses vibrations from smart phones to warn people about earthquakes.
The phone app _______ sudden shaking of the earth’s surface through sensors in smart phones. It is called MyShake. It is the work of four researchers at the University of California, Berkeley. They said they created a worldwide warning system that would _______ people and give them time to prepare. The MyShake app is _______ only for Android phones.
Smart phones are _______ accelerometers (加速度感应器). These instruments measure movement, like that of a car or airplane. MyShake uses phone accelerometers to measure seismic (地震的) activity. It has been _______ to know the difference between normal activity and earthquake movement. The software developers say their app is right 93 percent of the time.
A smart phone sends seismic information to the app developers. If the developers receive several notifications _______, it recognizes that an earthquake might be taking place or will take place soon.
Using information sent from the app, the network then _______ the location and strength of the quake in real time. MyShake can record magnitude 5.0 earthquakes at distances of 10 kilometers or less.
MyShake uses very _______ power, according to its developers. Only when seismic activity is _______ by the app does it become active and sends data to the network. The app works best when your phone is resting on a ________ surface, like a table.
The developers hope that MyShake can add to information collected by the U.S. Geological Survey. That U.S. agency has created the Earthquake Early Warning System, also ________ EEW. The EEW has deployed (部署) sensors for measuring quakes in many areas.
In places where no such equipment ________, MyShake may be the only method of early quake ________. The app also shows ways to stay safer during an earthquake. The developers say it will become more effective as more people use it.
“Our goal is to build a worldwide seismic network and use the data to________ the effects of earthquakes on us as individuals and on society as a whole,” say the researchers.
The developers say they hope to add a feature that would ________ people about a possible tsunami: a huge wave after an earthquake.
