Question

请帮我翻译一下这段话 很简单很简单！

有两组运动员，给第一组每天都吃那能量棒，不给第二组吃，研究两组运动员的跑步水平是否会提高。
如果第一组运动员中的一人是第二组运动员中一人的朋友，第二组就会知道第一组每天都吃能量棒，而自己这一组没有，但是他们不想就这么输掉，每天都很努力练习，结果两组的速度都变快了。这个实验就分不清能量帮是否有效。

Answer 1

楼上的英语？？？

In two teams of athletes, we supply one team (Team A) with energy bar for diet but not for another team (Team B). It is to find out whether the standard of jogging these teams of athletes can be improved?

If one of the athletes from Team A is a friend of the Team B, then the Team B will know that Team A has energy bar daily, but not for their team. In this case, Team B will work harder everyday in order not to loose out. Eventually, both teams will improve their speed in jogging etc.. This experiment hence can't distinguish whether the energy bar has to do with the improvement of the speed.

Answer 2

Two groups of athletes, give the first group everyday eat that bar, do not give a second group of eat, research two groups of athletes running level whether will improve.
If the first group is the second athlete, one of the friends in one group athletes, the second group will know the first group everyday energy bars, but own this group of no, but they don't want to lose, so every day very hard practice, the result two group of speed for speeding up. This experiment can not help clear energy is valid.

Answer 3

Two group of players for the first group all day for the energy sticks, not for the second group to study the two groups would raise the level.
If the first team player, a man is the second runner in a friend, the second group will know the first group all day for energy sticks, and the group, but they don't want to have lost, very hard to practice every day,The speed of the two groups were fast. this experiment will not help it.
