Прочитайте текст и сделайте задание. ПОМОГИТЕ, ПОЖАЛУЙСТА!!!!! The Olympic Games have a very long history. They began in 777 BC in Greece and took place every four years for nearly twelve centuries at Olimpia. They included many different kinds of sports: running, boxing, wrestling, etc. All the cities in Greece sent their best athletes to Olimpia to compete in the Games. For the period of the Games all the wars stopped. So the Olympic Games became the symbol of peace and friendship. In 394 AD the Games were abolished and were not renewed until many centuries later. In 1894, a Frenchman, Baron Pierre de Coubertin, addressed all the sports governing bodies and pointed out the significance of sports and its educational value. Two years later the first modern Olympic Games took place. Of course, the competitions were held in Greece to symbolize the continuation of the centuries-old tradition. In 1896 the International Olympic Committee was set up. It is the central policy-making body of the Olympic movement. It is formed by the representatives of all countries which take part in the Olympic Games. The International Olympic Committee decides upon the programme of the games, the number of the participants and the city-host for the Games. Over one hundred and fifty countries are represented in the International Olympic Committee now. Besides, each country has its National Olympic Committee. Summer and Winter Games are held separately. There are always several cities wishing to host the Games. The most suitable is selected by the International Committee.
