本次奥运会男子100米参赛的选手有80位，但是只有3位是历史上最快的短跑运动员。

There are 80 entrants in the men's 100 meters at the Olympics, but only three are the fastest sprinters in history.

这将是奥运会100米短跑历史上第一次包括了卫冕世界冠军（盖伊），世界记录保持者（博尔特）和前世界记录保持者（鲍威尔）的比赛。

It would mark the first time in Olympic 100 history the race would include the reigning world champ (Gay), the world recordholder (Bolt) and his predecessor (Powell).

众多因素为这三名巨星能否夺冠划上问号。

Various factors have hung question marks over all three favorites.

盖伊已经有1个多月没有比赛了。鲍威尔掌控压力的能力仍让人怀疑。

Gay has not had a race for over a month，and Powell's ability to handle the pressure is still questionable.
