4. The teaching mode must be natural and relaxed, the language expression should be fluent, and the body language and movements should be appropriate.

5. Interact with students in time. After the students answer the questions, they should make comments, such as: "This classmate answered very comprehensively/loudly/with good ideas".

The introduction of work experience is in the opposite order, starting from the most recent job and emphasizing the work experience that is beneficial to the new job. It is best to explain what position you have held, your actual achievements, achievements, etc. And the impact of your work on the original company.
