Juni, juli och augusti :)
Why do you wish to be a teacher? is incorrect. Why?
bli=become and vara=be, in the first case you are not yet a teacher, but you could be in the second case.
Larry Wylie it means different thing "wish" and "want"
Is "en" or "ett" not needed in this construction? Can it be used and if so is it unidiomatic?
"a teacher" should be "en lärare"
