    I went to see the film after supper. On my way to the      
cinema, I met the English woman, who lost her way.          
I gave up the chance see the film and took her to her       
hotel. While go there, I told her about great changes      
that had been taken place in the past few years           
and she she had told me something about her country.      
Although I missed the film, but I still felt very happy, for 
I had not only helped her out of trouble but practised     
my spoken English. If I had not worked hard on            
English, I would not have been able to help him.
