段2：①The trend in sports, though, may be obscuring an unrecognized reality: Americans have generally stopped growing. ②Though 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. ③And they aren’t likely to get any taller. ④“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 Chumlea of Wright State University. ⑤In 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.

段4：①Genetically speaking, there are advantages to avoiding substantial height. ②During childbirth, larger babies have more difficulty passing through the birth canal. ③Moreover, 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. ④“There are some real constraints that are set by the genetic architecture of the individual organism,”says anthropologist William Leonard of Northwestern University.

[A]Non-Americans add to the average height of the nation.
