Key points: (1) Overcome nervousness, anxiety and uneasiness, and be confident that you can successfully pass the defense.
(2) Pay attention to self-cultivation and be polite to guests. Whether listening to the teacher's questions or answering them, you should be polite.
(3) Understand the meaning of the question, grasp the main idea of the question, understand the purpose and intention of the defense teacher, fully understand the root of the question, and then answer to avoid the phenomenon of irrelevant answer.
(4) If you really don't understand a problem, ask the teacher humbly. Try to get the teacher's prompt and handle it skillfully. Face difficulties with a positive attitude, think and answer seriously, and don't give up on yourself.
(5) Speak at a moderate speed, neither too fast nor too slow. Too fast will make the members of the defense team unable to hear clearly, and too slow will make the defense teacher feel that the respondent is unfamiliar with this issue.
(6) Don't mention uncertain views and opinions in your defense.
