Just think about it: How long is 46 seconds ____46____ And it might take you that long to lace up your shoes. But on August 4, swimmer Pan Zhanle swam 100 meters in 45.92 seconds, and his team became the first non-American team to win the Olympic men’s 4×100m relay in more than 40 years. That was just one of China’s many breakthrough moments from this summer’s Olympics. Three days earlier, Pan shocked the world in the men’s 100m freestyle. Like a flying fish, he touched the wall in 46.40 seconds. ____47____
One thing that struck me was how young these champions are. ____48____

The 26-year-old isn’t sure about her chances for the 2028 Games. All athletes want gold medals, but like Zhang said in an interview, “It’s a competitive world. ____50____”
A. Some athletes, however, made history even without winning medals.
