英国奥运金牌数有望超08年记录
Team GB are hoping to secure the two gold medals which will allow them to surpass the tally of 19 won in Beijing.
英国队有望再夺两枚金牌，这将使其超越北京奥运会19枚金牌的记录。
Sir Chris Hoy is going for a GB record sixth Olympic gold - other GB cyclists after gold on the last day at the velodrome include Victoria Pendleton.
Hopes are also high in the dressage equestrian（骑马的） event and men's triathlon.
Meanwhile, PM David Cameron has attended an event to mark the 40th anniversay of the deaths of 11 Israeli athletes killed at the Munich Games.
He said the world must "never forget" the 11 Israelis and one German police officer killed by the Black September Palestinian group in 1972.
"As the world comes together in London to celebrate the Games and the values it represents, it is right that we should stop and remember the 11 Israeli athletes who so tragically lost their lives when those values came under attack in Munich 40 years ago," he said.
Mr Cameron said the 7 July London bombings, which killed 52 on London's public transport system in 2005, meant the two countries shared "the same determination to fight terrorism and to ensure that these evil deeds will never win".
Ankie Spitzer and Ilana Romano - the widows of two of the killed team-mates - were at the commemoration at London's Guildhall, which was also addressed by Labour leader Ed Miliband, Liberal Democrat leader Nick Clegg and International Olympic Committee president Jacques Rogge.
