[当]四年一度的奥运再次来临,你是否仍记得四年前的盛况?刘翔退赛的议论,奥运冠军的泪水,打着擦边球的各类体育营销,将所有人的感官塞满。四年后,北京奥运的影子留存于记忆,曾经灯火通明的比赛场馆,除了少数如鸟巢、五棵松体育馆和国家会议中心还常有人来人往,老山的小轮车赛道,通州水上公园的皮划艇赛场都几近荒废。 [When the Quadrennial Olympics is here again, do you still remember the spectacular four years ago? Liu Xiangs retiring argument, the tears of the Olympic champion, all kinds of sporting marketing with the goalkeeper clinging to the senses of all. Four years later, the shadow of the Beijing Olympics is kept in memory. Once the brightly lit competition venues, except for a few such as the Bird’s Nest, the Wukesong Indoor Stadium and the National Convention Center are also frequented by people. The Lao Mountain BMX track, Tongzhou water Park kayaking are almost abandoned.
