People who eat more than l60 grams of red or processed meat a day are 35 percent more likely to develop bowel cancer than those who eat less___________ (51)20 grams a day。according to one of the biggest nutrition investigations ever carried out．
The European Prospective Investigation into Cancer and Nutrition followed 478，040 men and women___________ (52)35 t0 70 from 10 European countries．
All subjects were free of cancer at enrollment between 1992 and 1998，but ___________ (53)an average follow—up of almost 5 years 1，329 bowel cancers had been
The subsequent analysis，published in the Journal of the National Cancer institute，confirms the long—held suspicion___________ (54)high intakes(纳入量)of red meat are associated with increased bowel___________ (55)risk．
After taking into consideration factors like age，sex，height，weight，energy intake，physical activity，smoking，and alcohol consumption，the investigators found that bowel cancer was ___________(56)with intake of red and processed meat but not chicken．
Risk of bowel cancer dropped with increasing intake of fish．Eating more than 80 grams a day of fish was associated___________ (57) a 31 percent reduction in risk compared with eating less than l o grams a___________ (58)。

根据下列文章，回答31～35题。
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.

A．illustrate the change of height of NBA players.

D．assess the achievements of famous NBA players.
