举办现代奥运会的初衷在于促进世界和平，但有时它却变成一个政治纷争的舞台。1936年的柏林奥运会最受争议。当时因为纳粹在德国主政，所以德国的犹太运动员被禁止代表德国队参赛。
The Olympic Games were interrupted twice during the First and Second World Wars.The event was not held in 1916，1940and 1944.
现代奥运会曾因两次世界大战而中断，1916年、1940年和1944年的奥运会都未能如期举行。
Science Helps Sport Save Valuable Seconds 依靠现代科技争分夺秒The modern Olympic Games were founded with the intention of improving health and education，promoting world peace，and encouraging fair and equal competition.But over the years，the Olympic saying，“faster，higher，stronger”，has pushed scientists as well as athletes to do everything possible to reach new levels.
举办现代奥运会的宗旨在于强健体魄，融教育于体育，促进世界和平，鼓励公正和平等竞争。多年以来，“更快、更高、更强”的奥运格言不断引领许多科学家和运动员想尽一切办法去追求新的竞技高度。
Doctors，engineers and coaches all use everything science has to offer to achieve that little bit extra in competition.The reason modern technology has become part of sport is very simple：winning is just as important as it was 2，500years ago at the Olympics of ancient Greece.
医生们、工程师们，还有教练们，他们充分利用科学的力量去实现竞技运动中的那一点点领先于人的优势。现代科技已然与体育运动融为一体，原因很明了：在现代奥运会上，获得胜利的重要性与2500年前古希腊奥运会时并没有什么区别。
Developments in technology have often been reflected in the methods of training and performance used at the Olympics through history.This technology falls into two main groups：improving an athlete’s performance in competition，and allowing results to be measured more accurately.
古往今来，科技的发展经常在奥运会体育训练方法和比赛的成绩方面体现出来。科技之于奥运，有两大主要功效：一为提高运动员的成绩；二是使比赛结果的计量更为精确。
One of the creations that has drawn the most attention is the new high tech swimsuit from Speedo，which will be used by most US swimmers in Athens.Until Sydney 2000，it was thought that the smaller the swimsuit，the faster the swimmer would travel.
斯皮多公司研发的一种高科技游泳衣备受关注。雅典奥运会时，美国大多数游泳健儿将身穿这种游泳衣参赛。截止到2000年悉尼奥运会，人们一直以为游泳衣愈小，运动员游的愈快。
“However，the fact that at the Sydney Olympics，28of the 33gold medalists were wearing the body covering Fastskin suit proved the theory was out of date，”said Andy Thomas，vice president of Speedo.
而斯皮多公司副总裁安迪·托马斯却说：“在悉尼奥运会上，33名游泳金牌得主中，有28位穿着覆盖全身的“鲨鱼装”。这就证明游泳衣越小速度就越快的理论已经过时。”
The company’s full body suit is supposed to make swimmers 3to 4per cent faster，particularly when turning or diving into the water.It is believed that the suit creates less water resistance as it moves，behaving more like a shark skin than a human skin.
该公司的全身覆盖型游泳衣被认为可以使运动员的速度提高3%—4%，尤其是在转弯或跳水时更为明显。身穿此种游泳衣在水中移动时，就像拥有一身鲨鱼的皮肤一样，可以减轻水的阻力。
The introduction of high tech equipment means that athletes in all sports，from the 100metres sprint to the pole vault，can now train more effectively and nourish their bodies better.
高科技装备引入体育运动领域意味着各种体育运动项目的运动员，不论是100米短跑选手，还是撑杆跳选手，现在都可以进行更为有效的训练，更科学地强身健体。
