问：关于21的核心要素，专家怎么看？ 答：The last time the USA hosted the World Cup, drinks breaks – or the lack thereof – became a scorching bone of contention.

The rules from on high decreed that players near the dugout could adjourn to the sideline for refreshments while play continued. However, since bottles were not allowed on the pitch, those further away had to try catching flimsy funfair-style plastic bags of water – sans goldfish – thrown from the touchline. Anyone who happened to be out of chucking range just had to flirt with heat stroke for the good of the tournament.
