1 . As she pulled herself over the summit of El Capitan, Emily Harrington knew she had made history.

It wasn't________. The US climber had powered on through the dark and dealt with a deep________to her head to become the first woman to free________ the difficult route in under 24 hours.

"I'd just________what it would be like and it was pretty much exactly what I pictured," Harrington said excitedly.

"It was incredibly quiet. It was super________. All the stars were out. It was just this really peaceful experience. I keep telling people that when great sporting________happen, a lot of times there's an________or there's a stadium. With climbing, it's not so much like that. It was just this really________special moment in this magical place. And it's something I'll never________."

Free climbers use just their hands and feet to climb, with a rope to________them if they fall. Such a dangerous and ________life-threatening________requires years of preparation, both mentally and physically.

Harrington had climbed this particular________over the course of six days in 2015 and had________tried three times to complete it within 24 hours.

However, an attempt last year ended in________after Harrington fell 50 feet, hit her head on a ledge(岩架), and ________concussion(脑震荡).

"It was very________. It was very serious initially and it________that I got really lucky and I did not suffer any long-term________," she added.

"It's definitely a mental struggle, coming over that hurdle, coming back into this year and________again." Finally she made it.
