For reading I copied an article from the Olympics website .I made some questions and see if you can answer them .
The athletics track at the Olympic Stadium is a 400m oval. For all track events the finish line is in the same place, at the end of the ‘home straight’.
The track programme comprises sprints, middle-distance and long-distance events for men and women; hurdles and steeplechase races; and relays. Most events start with heats, with the fastest athletes or teams progressing to semi-finals and then the final.
To become the fastest human being at a particular distance requires not only speed but also supreme fitness, strength and the ability to master challenging techniques, such as the start in sprints and clearing the barriers in hurdles and steeplechase events.
Short-distance sprint races are the 100m, 200m and 400m. These three events (each with men's and women's categories), along with two hurdles events for men and two for women, employ a crouching start using starting blocks.
The 100m, which determines the fastest human being and is one of the most eagerly awaited event at any Games, is run on a straight course. The distance was covered in 12 seconds at the Athens 1896 Games while Jim Hines (USA) became the first Olympian to dip below 10 seconds at Mexico 1968. Since then, the world record has been lowered primarily by American and Jamaican athletes.
The current men's 100m world record is 9.58 seconds, set by the greatest sprinter in history, Usain Bolt (Jamaica), at the IAAF World Championships in 2009. Remarkably, any athlete running the distance in under ten seconds covers ten metres in less than one second.
