I got points off on my English essay because I used "to be" verbs. I don't neccesarily understand - they seem like normal verbs to me, and other verbs look identical and she didn't mark them off. I looked on Wikipedia, but it has nothing on the subject, or at least, not in the way I'm referring to it as. What is a "to be" verb, and how would it look different from a normal verb? I'm guessing a "to be" verb is "I am fishing", correct? So, how would you say that you fish without making it a "to be" verb?
