Imagine the feeling of swinging at a baseball going 100 miles per hour—without leaving your living room，or being in race car as it roars down the track，while you are sitting on the couch.
    These are just some of the ways that sports business leaders say virtual reality （VR） will revolutionize how people train for and experience sports.Virtual and augmented（增強的）realities are together known as mixed reality （MR）. "American footballers are already using VR to better train their minds and read the field，" Ludden said. "This can allow players to perfect their skills without risking injury."
   Canadian company D-BOX Technologies designs and produces moving seats found in cinema and theme parks.It is now moving into sports，and shows its Formula One （F1）racing simulator （模擬器）.The seats stimulate the force of gravity，speed and every shaking as Fl champion Lewis Hamilton zips around city streets.
   A simulation seat uses pre-programed data now.Someday，though，it could use real-time information sent by the car. "They could broadcast live content through a network in pop-up theaters around the world，" Ludden said.Say you want to experience the true stress of a batter being up against major-league baseball pitcher. "You can have a heartbeat added to the sensation on the seat and then you can feel it，boom，boom，" Maheu explained. "When he swings and hits the ball，you can have an impact."
   One day，fans around the world could physically experience every game from their favorite player in real time.Ludden said that current and near-future technology could create "augmented stadiums" for live audiences.Panasonic launched its "Smart Venue" plans which included the overlaying of graphics，advertisements，player statistics and replays on the field of play at a pro football game. "If you are seated in the cheap seats，you can see this really useful." "Fans may someday join in stadium wide games，using the field as a virtual gaming platform，" Ludden added.

   More than 78 percent of about 27，600 respondents to a poll on voted in favor of the idea of Li Jing，who is also the mayor of Meishan city in South-west China's Sichuan province.Li said the lunar new year festival holiday was too short for family reunions，especially for the nation's 220 million migrant workers.
   With hundreds of millions of people on the move during such a short time span，the holiday puts great stress on the public transport system and suppresses tourism，she added.She suggested the holiday be extended and cover the three adjacent（毗連的）weekends，which means the public could take a total of 16 days off and floating population could spend the Lantern Festival，which falls on the 15th day of the lunar new year，with their families.
   People would then have sufficient time to fully enjoy the traditional holiday with their families，Li said during an interview with People's Daily Online on Friday.
   Most online voters agreed that extending the holiday will ease the burden on public transport and strengthen family ties. "The Spring Festival is an occasion for family reunions and should be longer than the National Day holiday，" one responder said in an online post. "Every year，I wish I could spend more time at home for the Spring Festival，but I always have to go back to work.I hope the NPC will approve this proposal. "
   Another online comment read： "Extending the Spring Festival holiday could prevent the annual transportation crush，which has in recent years resembled an exodus（出走）of fleeing refugees（難民）".
   Most of the about 13 percent who opposed the idea cited difficulties readjusting to work after the break.Some pointed out that office moral （士氣）was generally low during the first week after the holiday. "After the six-day holiday，many people come back to work feeling absent-minded， " one respondent said.Some who opposed the extension suggested adding the Lantern Festival as an official holiday.

3．Surfing the Internet for fun will make you a better employee，according to an Australian study.
   The University of Melbourne study shows that people who use the Internet for their own reasons at work are about 9 percent more productive than those who do not.Study author Brent Coker said， "Surfing the Internet at times helps increase an employee's attention."
   "People need to relax for a bit to get back their attention，" Coker said on the university's website. "Having a short break，such as a quick surfing of the Internet，helps the mind to rest itself，leading to a higher total Internet attention for a day's work，and as a result，increases productivity（生產(chǎn)效率），" he said.
   According to the study of 300 workers，70 percent of people who use the Internet at work surf the Internet for their own reasons during office hours.Among the most popular surfing activities are searching for information about products，reading online news，playing online games and watching videos. "Firms spend a lot of money on software to block their employees from watching video，using social networking sites or shopping online，" said Coker. "That's not always a good idea."
   However，Coker said the study looked at people who surfed the Internet in moderation（適度），or were on the Internet for less than 20 percent of their total time in the office. "Those who spend too much time surfing the Internet will have a lower productivity than those without，" he said.
