My Comment

The first Exercises were easy, but I have one doubt with one exercise.
I think that it is very interesting, but I need to understand some sentences. I shouldn't forget the final "S", I think that this is a very common mistake, so I need to be more careful.
Has it ever happened to you that you write something and believe that is correct? but, when our teacher checks my text, she finds many mistakes... yes this is my life...
Some day, I'd like to impress her, yes some day...
