1. FIRST GOLD: Seven golds are up for grabs. China's Yi Siling took the first in the women's 10-meter air rifle.
2. ALL TO DO: Michael Phelps barely, barely qualified for the final of the 400-meter individual medley. He's in the unpopular Lane 8. Can he recover?
3. US WOMEN: They play Colombia at soccer and Croatia in basketball.
4. CYCLING: Britain is hoping for an early gold in the men's cycling road race, with Mark Cavendish the man to beat. Also on the team: Bradley Wiggins, who's just won the Tour De France.
5. BIKINIS: Fear not, fans of the beach volleyball bikini. Talk of cold weather stoked fears that the women would go for shorts and T-shirts. That's not happening.
