Annoying English teacher?

I don't like my English teacher, even though she's nice and the rest of the cl like her. I'm used to getting really good grades in English but she hardly ever seems impressed with my work and I feel like nothing I write is good enough but I can't ask her what to do differently because I don't think she'll understand my point of view. I think it might be a case of a personality clash or something. I find her extremely irritating because whenever she reads out loud she always pronounces words wrong, like for example we're studying Hamlet at the moment and every time she reads the word vengeance she pronounces it as if it was spelled 'vengeanance' and she pronounces a lot of other words wrongly as well and it really gets on my nerves and I want to correct her but if I do everybody looks at me as if I'm being really cheeky or something, so I just keep my mouth shut but it really annoys me when she pronounces words wrong and explains things wrong, but I feel like it's too trivial to question her on. How can I get along being in her cl? She annoys me so much that I don't like English anymore, and I've always been really good at it ever since I was in primary school.
