      I had an interested experience last year. After I had       
left a small village in the south of French, I drove on to  
the next town. On the way, a young man waved me. I            
stopped and he asks me for a lift. As soon as he had got     
into the car, I said good morning to him with French and      
he answered in the same language. Apart from a little         
words, I don’t know any French at all. None of us spoke      
during the journey. I had nearly reached to the town, when  
 the young man suddenly said, very slow, "Do you speak    
 English?" As I soon learned, he was English him!            		1. ____________
