The disparity in athletic achievement throws up so many sensitive questions of race and human difference that it is rarely discussed in public. (26) But now two US academics have risked controversy by publishing a theory that attempts to explain the contrasting performance of black and white athletes using the laws of motion. (27)They argue that black sprinters have a 0.15 second advantage over their white rivals because they tend to have a higher centre of gravity, meaning they can fall to the ground more quickly between each stride. Conversely, having a lower than average centre of gravity helps white swimmers because their speed is determined by the height they can get above water. More of their upper bodies are above the waterline, so they can generate and ride larger waves. (28) Adrian Bejan, a professor of mechanical engineering at Duke University in North Carolina, and Dr. Edward Jones of Howard University in Washington said the theory completely accounted for the increasing racial segregation of Olympic winner stands. The last 25 men’s 100m sprint world record holders have been black, while white swimmers have held the 100m freestyle world record since 1922. "What’s a disadvantage in one medium is an advantage in another," he said. (29)Equality campaigners have always resisted attempts to suggest that particular races have inbuilt athletic superiority, claiming that medal trends are best explained by the popularity of different sports in different communities. The lack of swimming facilities in Africa and black regions of the US have also been cited as a reason for white dominance of the pool.
26. What do the two US academics try to explain?
27. What is the reason for black athletes to run faster than white ones?
28. How does Adrian Bejan feel about the theory when it comes to Olympics?
29. What do equality campaigners think is the reason for the difference in athletic performance?
选项
A、Black athletes tend to have a higher centre of gravity.
B、Black athletes tend to have longer legs and bigger strides.
C、Black athletes tend to fall to the ground more quickly.
D、Black athletes tend to use their upper bodies more.
答案
A
解析
事实细节题。短文指出,在赛跑运动中,黑人比白人多出O.15秒的优势,这是因为他们的重心更高,这样他们迈步时能更快落地。C)是强干扰项,他们落地更快是重心高的结果,不是跑得快的根本原因。
