The stands are full of spectators enjoying the Olympic action on a glorious summer day with a familiar London landmark resplendent in the background.
看台上坐满了观众，大家正在某个宜人的夏日观看伦敦奥运会比赛，熟悉的伦敦地标式建筑在场馆背景中闪现。

Never mind the fact that British summers can be damp（潮湿的） and drizzly（下毛毛雨的） -- center court at Wimbledon has a roof for a good reason -- and forget dire warnings of airport-style security and transport congestion（拥挤，充血） .
The 'overlay' vision, as organizers move into a new phase of the preparations with the '500 days to go' mark coming up next month, is strawberries and cream, picnics in the park, street parties and long, lazy summer evenings outdoors.
"We started this process two years ago and we looked at the festival nature of things," said John Barrow, a senior principal for architects and venue designers Populous.
"We looked at the Festival of Britain in 1951 and explored the delight in the innovation post-war...we also looked at the legacy this brought.
"We then explored the quintessential（精髓的） aspects of what makes a London event...and looking at something like Wimbledon we think that atmosphere of informality, laced with fun and festival, is really something we want to inject into London 2012," added Barrow.
"It does come down to（归根结底） the strawberries and cream and the long summer nights. We are trying to really create that type of atmosphere, albeit（虽然，即使） on a much bigger scale."
