和老师讨论论文怎么说英语

To discuss a paper with your teacher, you could say something like "Can we talk about the paper I'm writing?" or "I'd like to discuss my paper with you." If you want to be more specific, you could say something like "I want to get your feedback on the direction of my paper" or "I have some questions about the sources I'm using for my paper and I'd like to discuss them with you." Ultimately, the exact phrasing will depend on the specific context and your relationship with your teacher.
