     One of the roles of the International Olympic Committee(IOC)is to choose the host city for

the Olympic Games.The host city election takes place in a country which does not have a candidate

city for the Olympics in question.Except for unusual circumstances,the election is held seven years

before the Olympic Games take place.There have been two phases leading to the election of the

host city since December 1999.

     Phase 1:applicant cities

     Any city that wishes to host the Olympic Games must be proposed to the IOC by its National

Olympic Committee(NOC),with a letter from the city itself.During the first phase,which lasts around

ten months,each applicant city must answer a questionnaire to provide general information about itself.

Then the applications will be examined carefully.A number of things will be considered,such as

government support,public opinion,general infrastructure(基础设施),safety,accommodations and

transport.The IOC Executive Board(执行董事会)will determine which applicant cities will be accepted

as candidate cities.Only candidate cities can continue?with the procedure.

       Phase 2:candidate cities

      Candidate cities must provide a candidature file according to the instructions given by the IOC.After

all the files are examined and the IOC Evaluation Commission(评估委员会)produces its report,the

IOC Executive Board draws up a list of final candidate cities.The general assembly of the IOC then takes a vote on the host city.
