是啊，博尔特可真是了不起啊，他不仅仅是100米200米的奥运会冠军，同时也是这两个项目的世界纪录保持者。当然在这次北京世锦赛上他也成功卫冕。

Yes, Bolt is really amazing. He wasn't just the 100 meter and 200 meter Olympic champion, at the same time he's also the holder of the world record for these two events. Of course, at the championships in Beijing this time, he successfully defended his record.
