Input:  Person1:     the May holiday is coming up soon . Are you planning on going on vacation ? 
 Person2:  I am . I just went to the travel agent ’ s and picked up these brochures . 
 Person1:      where are you planning on going ? 
 Person2:  I fancy going to Tibet for a few days . Have you ever been there ? 
 Person1:      I went a long time ago , before they built the new train that can take you there . 
 Person2:  would you recommend going there for a few days ? 
 Person1:      personally , I think it ’ d be better to go when you have more time . A few days isn ’ t really enough to get acclimatize yourself and to go on a few excursions outside of the capital . 
 Person2:  you ’ re probably right . What do you think about Yangshao ? 
 Person1:      it ’ s a beautiful city , but I think it ’ s become too touristy . How about going to a cosmopolitan city like Shanghai or Hong Kong ? 
 Person2:  I ’ d like to get away from the big city life . 
 Person1:      maybe you should consider going to a hot springs resort outside of Beijing . I heard they are very relaxing . 
 Person2:  I guess if I only have a few days , I should probably think about going somewhere that isn ’ t far away . 
 Person1:      since the May holiday is the high season , you should probably call ahead to reserve a room . Here ’ s the phone number . 
 Person2:  thanks ; I ’ ll give them a call later .
