1, lecturers often slip of the tongue:

You, me, him

Your country/our country

Your company/their company

As far as I know

"contentment" and "satisfaction" ...

2. Actions often taken by lecturers

criticize

Stand upright

Example: the end/oh, and so on

This one?

Repetitive statement

Don't imitate the habits of other countries and others.

I suggest you take more training. It is good for the International Association of Professional Trainers.
