问题     In the opening match of soccer’ s World Cup Friday, German midfielder Torsten Flings【S1】______an amazing goal from 40 yards out. The ball【S2】______off straight and then tailed sharply to the right in the last 10 yards or so. It was an【S3】______shot, but with a different ball it might have been a simple save.
    A scientist has explained why a new ball being used in this year’s World Cup is【S4】______goalies (守门员). The new Adidas Teamgeist football, as it is called, has 14 panels instead of the 26 or 32 that【S5】______create the hexagonal pattern(六角晶格)o Fewer panels means fewer seams(接缝), which will make the ball behave more like a baseball, says Ken Bray, a sports scientist at the University of Bath in the UK. Complex【S6】______of air cause a spinning ball to drift toward the side that’ s spinning away from the ball’ s direction of movement. A ball that’ s net spinning can bounce around unpredictably.【S7】______rely on this physics when throwing knuckleballs(不旋转球). A good knuckleball is crazy because the ball rotates lazily in the air and the seams【S8】______the air flow around the ball at certain points on the surface, Bray said.
    "With a very low spin rate, which occasionally happens in football, the panel pattern can have a big influence on the【S9】______of the ball and make it more【S10】______for a goalkeeper," Bray said last week.
