每日翻译练习[八七]

If athletes want better performances, they should train at high altitudes. At higher altitudes, the body has more red blood cells per unit volume of blood than at sea level. The red blood cells transport oxygen, which will improve performance if available in greater amounts. The blood of an athlete who trains at high altitudes will transport more oxygen per unit volume of blood, improving the athlete’s performance.

 

Which of the following, if true, would be most damaging to the argument above, provided that the athlete’s heart rate is the same at high and low altitudes?

 

  •  Scientists have found that an athlete’s heart requires a period of time to adjust to working at high altitudes.
  •  Scientists have found that the body’s total volume of blood declines by as much as 25 percent at high altitudes.
  •  Middle-distance runners who train at high altitudes sometimes lose races to middle- distance runners who train at sea level.
  •  The performances of athletes in competitions at all altitudes have improved markedly during the past twenty years.
  •  At altitudes above 5,500 feet, middle- distance runners often better their sea-level running times by several seconds.

答案:(B)

 

读题:如果运动员要有好的成绩,他们必须在高原训练。在高原体内每单位体积血中的红细胞比在海平面处多。红细胞传送氧气,而氧气量大的话会促进成绩。在高原训练的运动员每单位体积血内会传送更多的氧气,从而提高运动员的成绩。

 

问题:下面哪一个,if true,最能够削弱上面的论述,假设运动员的心律在高低海拔一一样?

 

a. 科学家发现运动员的心脏需要一段时间来适应在高原工作。

b. 科学家发现体内总的血量在高原减少了25%。

c. 在高原训练的中距离赛跑运动员有时输给在海平面处训练的运动员。

d. 在所有海拔上,运动员在比赛中的成绩在过去20年中的都得到了显著提高。

e.在海拔5500米以下,中距离赛跑运动员的成绩要比海平面出训练的运动员好。
