At the end of the 19th century the French nobleman
Pierre de Coubertin ['pjer də 'kubz:tən] got the idea
to bring the Olympic Games back to life. With the
help of the people who supported him, he organized
the first modern Olympic Games. So the Olympic
Games returned to our lives in 1896. They were a
Athletes from thirteen countries came to
Greece and had competitions in nine sports. Russia
took part in them too. Now the number of countries
taking part in the Olympic Games is much larger
and so is the number of athletics events.
Pierre de Coubertin As in ancient times, the Olympic Games take place
every four years. In 1926 the tradition of the Win-
ter Olympic Games also began. The noble idea of the Games is to make
everybody friends by meeting on football fields, courts and stadiums and
to live in peace. The International Olympic Committee [kə'miti] heads the
Olympic movement. Among other things the Committee chooses the place
for the coming Olympics. It is a great honour to become an Olympic
city. In 1980 Moscow joined the family of Olympic cities and in 2014
Sochi did. The XXII Olympics in Sochi were a huge success.
The Olympic Games are probably the most
important international sports event. Millions
of people watch them all over the world.
They support their Olympic teams and favou-
rite athletes who fight peaceful battles in
honour of sport. A lot of people enjoy the
opening and closing ceremonies of the Olym-
pics, which are colourful and original.
Many things have changed but as in ancient
times, winners of the Olympics become national
heroes in their countries.
