These days we can often see students doing morning exercises to stay    1     (health). Most of   you probably do the same kind of exercises. But my school exercises have gained     2     (popular)   because of their local and special designs.

Students at a middle school in Mianyang, Sichuan Province, combine Sichuan Opera with their exercise. Shen Junhua,     3     is in charge of organizing the school's exercises, said, "Sichuan Opera is     4     local opera, but now it is facing a problem because few young want to learn it.

2 . 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（增强的）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 （模拟器）. 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.

3 . Exercise for a Better Brain

Most of the time, your brain is the boss of your muscle—directing how you hit a ball, play the piano, or open a cereal box.    1    When you're active, they send chemical signals telling your brain, "Hey, it's time to grow!" Recent research suggests physical activity is good for your brain and encourages the birth and growth of new brain cells.

In a study, people who ran for 45 minutes three days a week boosted their levels of a brain-derived neurotrophic（神经营养的）factor, a chemical that acts like fertilizer for new brain cells.    2    

Studies suggest that in younger adults, exercise can add to the overall number of cell in the hippocampus（海马体）.    3    It's a good deal because these new brain cells are very active and get involved in more memory circuits than older cells do. At any age, you might notice that you have an easier time remembering things after you start a new exercise.

    4    If you're inactive, walking around the block may be the only way to encourage neuroplasticity. People who don't like to move but tried to walk daily by 7500 steps or more had bigger brains than those who didn't exercise—the same to 1.4 to 2.2 fewer years of brain aging. So it is advisable for people at any age to get involved in light activity, such as doing housework, shopping, gardening, or walking the dog.    5    

A．Again, a little goes a long way.

B．Tips have been offered as to how to properly exercise.

C．After four months of workouts, their scores improves on a memory test.

D．Besides this, studies have also suggested that dying cells can be cleared with regular exercise.

E．But when it comes to growing new brain cells, more and more researches show that when you exercise, your muscles take charge.

F．Exercise also helps keep brain cells alive longer and replaces old cells with new ones.

G．The more light activity study participants logged, the greater the overall size of their brains.

4 . The Biggest Stadiums in the World

People have been pouring into stadiums since the days of ancient Greece. In around 80 A.D., the Romans built the Colosseum, which remains the world’s best known stadium and continues to inform contemporary design. Rome’s Colosseum was 157 feet tall and had 80 entrances, seating 50,000 people. However, that was small fry compared with the city’s Circus Maximus, which accommodated around 250,000 people.

These days, safety regulations-not to mention the modern sports fan’s desire for a good view and comfortable seat — tend to keep stadium capacities (容量) slightly lower. Even soccer fans tend to have a seat each; gone are the days of thousands standing to watch the match.

For the biggest stadiums in the world, we have used data supplied by the World Atlas list so far, which ranks them by their stated permanent capacity, as well as updated information from official stadium websites.

All these stadiums are still functional, still open and still hosting the biggest events in world sport.
