　　(2019·厦门模拟)Did you know that the color of uniforms can influence the performance of an athlete? It may sound strange，but a study suggests this might be true.

　　Two British scientists studied the results of four sports in the 2004 Athens Olympic Games where the athletes had been given either a red or a blue uniform.They discovered that when there was a big difference in the score，color had no influence on the result.But if it was a close match，the athlete in a red uniform was more likely to win.Then they looked at the uniforms of the soccer teams at the Euro 2004 tournament.Again，teams wearing red won more games.

　　The two scientists got their idea from earlier studies of wild animals.It had been discovered that when a male show red on its body，it sends a signal of its power and strength.For example，in many kinds of monkey，the more the male shows off its red scars，the more females it can attract.

　　Based on this fact，the British scientists thought that the idea might work for humans，too.According to them，when an athlete sees a competitor in a red uniform，he gets a feeling that his competitor could be stronger than him.And that_kind_of_feeling may have a bad influence on the player's performance in the actual game.

　　Although the idea is interesting，most people don't accept that color signals in the animals world can really be useful to humans in sports.They think that it is unreasonable to develop an idea based on such a small number of examples.Much more research has to be done to prove the influence of uniform colors on the performance of athletes.
