The statement as it stands makes no sense: the word 'between' seems to be missing. I'm guessing that the statement should read like this: Most of Australia lies BETWEEN twenty degrees and thirty-five degrees south. Note that you need to say 'degrees' rather than 'degree', as this word is plural. NB The phrase 'read orally' is very odd. This misuse of the word 'oral' and 'orally' is very typical of Chinese learners. In fact, we could have guessed you were Chinese from this question alone. A more natural phrasing might be, for example, "How do I read this aloud?"

Thank you

Yes, but degrees as in plural not degree (need the 's' at the end :)
