The trend in sports, though, may be obscuring an unrecognized reality: Americans have generally stopped growing. Though typically about two inches taller now than 140 years ago, today's people-especially those born to families who have lived in the U. S. for many generations-apparently reached their limit in the early 1960s. And they aren't likely to get any taller. "In the general population today, at this genetic, environmental level, we've pretty much gone as far as we can go," says anthropologist William Cameron Chum-lea of Wright State University. In the case of NBA players, their increase in height appears to result from the increasingly common practice of recruiting players from all over the world.
Growth, which rarely continues beyond the age of 20, demands calories and nutrients-notably, protein--to feed expanding tissues. At the start of the 20th century, under-nutrition and childhood infections got in the way. But as diet and health improved, children and adolescents have, on average, increased in height by about an inch and a half every 20 years, a pattern known as the secular trend in height. Yet according to the Centers for Disease Control and Prevention, average height--5 '9" for men, 5'4" for women--hasn't really changed since 1960.
Genetically speaking, there are advantages to avoiding substantial height. During childbirth, larger babies have more difficulty passing through the birth canal. Moreover, even though humans have been upright for millions of years, our feet and back continue to struggle with bipedal posture and cannot easily withstand repeated strain imposed by oversize limbs. "There are some real constraints that are set by the genetic architecture of the individual organism," says anthropologist William Leonard of Northwestern University.
Genetic maximums can change, but don't expect this to happen soon. Claire C. Gordon, senior anthropologist at the Army Research Center in Natick, Mass ensures that 90 percent of the uniforms and workstations fit recruits without alteration. She says that, unlike those for basketball, the length of military uniforms has not changed for some time. And if you need to predict human height in the near future to design a piece of equipment, Gordon says that by and large, "you could use today's data and feel fairly confident."

听力原文： Wilt Chamberlain is retired now. He used to be a famous basketball player. He has set 65 different records, and still holds many of them. During the final years of his career, he drew a large salary and became very wealthy. He even built himself a 1.5 million dollars' house. Yet, despite his personal success, he led his team to only one championship. His team often won enough games to qualify for the final rounds, but they almost always lost in the finals. As a result, Wilt became determined to win one more championship before he retired.
In 1972, while Wilt was playing against a New York team, he fell down and hit his wrist on the floor. He felt pain immediately and knew he had hurt himself badly. When a doctor examined Wilt, the doctor confirmed Wilt's fear. The doctor told Wilt that he had broken a bone in the wrist and that he could not play any longer.
Wilt didn't listen to his doctor's advice. The next night, with his many fans watching in surprise, he not only played the entire game, but he was outstanding. His team won the game and the championship. Wilt had realized his dream--to be a winner one last time.
