考研英语阅读命题思路透析和真题揭秘(44)
In the early 1960s Wilt Chamberlain was one of only three players in the National Basketball Association (NBA) listed at over seven feet. If he had played last season, however, he would have been one of 42. The bodies playing major professional sports have changed dramatically over the years, and managers have been more than willing to adjust team uniforms to fit the growing numbers of bigger, longer frames.
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 Chumlea 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."
34. We learn from the last paragraph that in the near future
[A] the garment industry will reconsider the uniform size.
[B] the design of military uniforms will remain unchanged.
[C] genetic testing will be employed in selecting sportsmen.
[D] the existing data of human height will still be applicable.
[答案] D

文章最后一段最后一句话指出"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.""(如果你为了设计一款新的设备而需要预测人类在不久的将来的身高变化,Gordon认为基本上"你可以采用目前的数据,而且还可以感觉非常自信"),可见显然D选项符合原文。A选项与原文的意思相反,可以排除。B选项强调的是服装的设计,而不是原文的服装尺寸这个重点,因此也可以排除。而C选项也与最后一段无关,也是错误答案。
[题目译文]
我们可以从最后一段中得知,在不久的将来
[A] 服装业将重新制定制服尺寸
[B] 军队制服的设计不会有很大变化
[C] 基因测试会被用于遴选运动员
[D] 现有的人类身高数据将可以适用
