As long as you write a paper, you are familiar with the contents.
You don't have to be afraid to reply.
But in case he asks you questions, you won't.
Then don't be afraid.
You don't have to answer all his questions.
All you have to do is answer one of the points he asked you.
Needless to say, as long as you have something to say, you must answer it very accurately.
It's good to have a point.
The most important thing is to be familiar with your paper.
Or you can see if your classmates have answered, and you can listen to their answers.
Opening remarks:
Good morning, teachers! My name is xxx, and I am a student in xxx class. My thesis topic was completed under the careful guidance of teacher xxx. Here, I would like to express my deep gratitude to my tutor and all the teachers who participated in my thesis defense. Next, I will report the purpose and main contents of this paper to all teachers and ask them to criticize and guide.
Conclusion: Finally, I want to talk about the shortcomings of this paper and the system. The process of writing and revising this paper is also a process in which I become more and more aware of my lack of knowledge and experience. Although I try my best to collect materials and use what I have learned to write my thesis, there are still many shortcomings in the thesis, which need to be improved. Please criticize and correct me, so that I can learn more in my future study.
thank you
I will reply tomorrow. Good luck and fight together!
