100 metres in 8 seconds?

Many contemporary① amateur athletes would have broken world records if they had taken part in② the first Olympic Games. Since then, records have fallen in track and field③ year after year④ as athletic performances have continually improved.

If records fall, it is usually due to better equipment, training and diet, but recently, improvements have begun to slow down⑤. At the 2000 Olympics, only three runners achieved Olympic bests⑥ with no worldrecords. Some expert s predict a ceiling⑦ for many events, such as 9.5 seconds for the 100 metres - Maurice Greene's current record is 9.79 seconds.However, past predictions have nearly always been proved wrong.

When we talk about breaking records⑧， we come across the issue of performance­enhancing⑨ drugs. These drugs are originally developed to help people with illnesses⑩， but in the wrong hands⑪， they create supreme⑫ athletes making them faster and stronger than is normal for human beings. Taking these drugs⑬ is known as "doping⑭" and although they enhance performance, they also cause serious health problems⑮ in later life for those who abuse⑯ them.
