Input:  Person1:     Are you ok , Chuck ? You look pale .  
 Person2:  I'm fine , Katherine . I just stayed up late last night working on my Chinese .  
 Person1:      Oh , poor you . You know what ? I found a new way to learn Chinese and it works very well .  
 Person2:  You did ? Do tell me . I've spent all these months trying to learn something new about it , but I've made little progress !  
 Person1:      Sure . I'm learning Chinese through songs .  
 Person2:  So you're learning Chinese songs ?  
 Person1:      You can say that . I can actually sing some of them now .  
 Person2:  That's a real achievement . How did you do that ?  
 Person1:      I start by listening to the song a few times and after several times I am able to follow the singer .  
 Person2:  It makes sense .  
 Person1:      It does . I've learned some Chinese folk songs this way . They are clearly presented and easy to follow .  
 Person2:  Can Join you , Katherine ? I do want to have a try .  
 Person1:      Why not ? I downloaded a beautiful song the other day . We can learn it together now .  
 Person2:  Great . Do you think we need a Chinese dictionary ?  
 Person1:      Yes , just in case we run into me new characters .  
 Person2:  Ok . I will bring it with me .
