Roberto is a student who struggles with English starting at a new school.
What would you like to drink?
Double negative - One struggle Roberto will have is understanding that double negatives are not allowed in English. He is accustomed to speaking that way in Spanish, but it's not considered proper English when it translates
Here to play futbol
Another struggle Roberto will face is not hearing or pronouncing his "s" after words. It will be a struggle for him to learn this as he continues to learn English
Roberto will also struggle understanding regional dialects that are specific to the region he moves to. In Mexico, he may have referred to a drink as a soda pop, but depending on the region he moves to, it could take a different meaning
Roberto will have to learn that even though some words sound similar, they can be very different. In this case, both sports sound very similar, but can not be more different than they can be
Uh, this is football buddy
Until Roberto is able to understand the differences in dialect, he will feel discouraged and want to go back to his old life. Over time, it will get easier for him and he will miss his old life. When he does learn the differences in dialect though, things will get easier and he will begin to love his new home.
