1. Briefly explain the reason, process and achievement of writing your thesis.

2. Praise the teacher's high quality and express reverence for him.

I am not sure about the thesis, so please ask the teacher for advice.

4. I really appreciate the teacher's concern for you all the time. I hope the paper will pass smoothly under the guidance of the teacher. You will always remember your teacher's kindness.

Hehe, it can't be wrong to follow these points.

Absolute personal feelings, selflessness.
