I'd like to know more about the difference between "how to be" and "how to become." My textbook(for junior high students) says that "how to be a teacher" means how to behave as a teacher or the ways you have to take when you teach something as a teacher, whereas "how to become a teacher" means exact the way to become a teacher, that is, the way you have to take to get a teaching job. I think "how to be a teacher" doesn't always mean that above. It depends on the situation or the context. isn't it?
Thank you, Florentia52. You've got exactly my point! Not only me but Japanese students have used such sentences you showed as an example. If the sentence you mentioned above implies you "aren't" a teacher now, "how to be a teacher" doesn't always implies you "are already" a teacher....like if a junior high student says, "I want to know how to be a teacher", that seems to indicate they want to know how to "become" a teacher. I'm now wondering if I should tell my students about the difference, how to be and how to become in that way the text says. It must be absolutely, totally, definitely confusing for my students.
