Input:  Person1:     Hey ! How was your first day of class ? I ’ m in level two and I ’ m loving my class this semester ! It ’ s great being in a class of international students !  
 Person2:  Mine was ok , except that no one in my class speaks English . I guess it will force me to converse in Chinese more in class so at least I should improve a lot this semester .  
 Person1:      That ’ s both fortunate and unfortunate . It ’ s the United Nations in my class ! We have people from all over the world ! There are three Germans , a Pole , a Scottish , two French , an American , a Brazilian , a Chilean , a New Zealander , though he prefers to call himself a Kiwi . Who else do we have ? Oh , we also have a Moroccan , a Togolese , a Pakistani , and two Indonesians !  
 Person2:  That ’ s quite the array of nationalities . Everyone in my class is from Asia , except me . There are a few South Koreans , several Japanese , Malaysian , Thai , Singaporean , Filipino , Kazakhstan , and one Russian .  
 Person1:      Well , I think you ’ re pretty lucky actually . You ’ ll have the opportunity to learn so much about Asian culture .  
 Person2:  I guess so , but I think it ’ s going to be hard to relate to my classmates , especially with the language barrier . I think I might change classes .  
 Person1:      Don ’ t ! Stay the course ! Your spoken Chinese will be eternally grateful . I bet you it will even surpass mine with all that practice .  
 Person2:  I highly doubt it . Your girlfriend is Chinese .  
 Person1:      Well , there is that , yes .
