Athletes, coaches and doctors were in Washington D.C. yesterday. President Obama was holding the first White House Healthy Kids and Safe Sports Concussion Summit. He was introduced by a teenage soccer star whose multiple concussions eventually took a tall on her athletic and academic performance. So, the goal of the summit is to find new ways to figure out how serious head injuries are, when they happen and how to treat them more effectively in the days ahead.

昨天，运动员，教练员和医生都聚集到了华盛顿。在那里，美国总统奥巴马正在白宫首次举行健康儿童和安全体育运动峰会。他被介绍了一个曾经患多种脑震荡而最终在运动和学业上都取得优异成绩的青少年体育明星。所以这次峰会的主题目标是清楚脑部疾病的严重性和发病情况，以及如何做到提前预防。

The president said that sports are vital to the country, that they are fundamental to American culture. But because, he says, there are no solid numbers on how often concussions happen in football and other contact sports, better research, better equipment and better methods of addressing head injuries are needed.

奥巴马指出运动作为美国文化的一个基本项目，对国家的发展有着至关重要的作用。但是因为没有具体的数字表明脑震荡在足球运动和其它接触类运动中发生的几率是多少，所以更完善的科研，更先进的设备和更有效预防脑部伤害的方法是现在最需要的。
