Input:  Person1:     Aren ’ t you interested in watching the Olympics ? There have been some excellent performances by athletes from all over the world .  
 Person2:  I just don ’ t find it very interesting .  
 Person1:      I think it ’ s wonderful to see people from all over the world taking part in such a great event .  
 Person2:  I think that for a lot of people , it ’ s just a way to try and show their country is better than other countries .  
 Person1:      I think the Olympics help to promote world peace .  
 Person2:  I ’ m not sure about that . We still have many wars in the world . I think that the idea behind the Olympics is a good one , but the reality is that during the Olympics countries compete . There ’ s no real spirit of cooperation and people are usually not very friendly to each other .  
 Person1:      You are so pessimistic ! The Olympics is a great opportunity for athletes to demonstrate their speed , skill , agility and strength . Most people hope to see someone from their country win , but I think that they are just happy to see good performances by any athlete .  
 Person2:  Well . I think that the most amazing performances are by athletes who participate in the Paralympics .  
 Person1:      Now there we are in agreement !
