In the training session example, Darby Laai practices a sample IELTS task from Part 1 of the test. The English Teacher follows the task prompt, and he waits until the appropriate time to deliver his feedback comment.

English Teacher: Do you like cooking?
Darby Laai: I do.
English Teacher: Why?
Darby Laai: I think I would have to say the reason is that I find it relaxing. 

English Teacher: How often do you cook?

Darby Laai: Hmmm...let's see...I suppose about 4 or 5 times a week.
English Teacher: Why?
Darby Laai: I guess it's because I just don't have time to cook more than that. You see, I often cook a big meal and then have the leftovers the next day.
English Teacher: How important is it for a person to learn how to cook?
Darby Laai: Extremely important. Especially vegetarian food.
English Teacher: Oh? Why?
Darby Laai: I think I would have to say that it is because eating out can be really expensive. Especially for these fancy vegetarian girls these days...And there comes a time when everybody is short of money...kind of like all my artist friends...so cooking is a good skill to have.
English Teacher: Uh huh...Ah hem...Well then ok...Do you ever cook for other people? Darby Laai: From time to time yeah.
English Teacher: Why?
Darby Laai: I suppose it's because it's just fun to have people over and enjoy a meal together. Ummm...are there any other ways to say "have people over"? I heard it on TV and I was wondering about that.
English Teacher: Good question....but better to write that down and prepare that question for either the beginning of the live class or for after the training session.

Darby Laai: Ummm...ok. Fair enough I'll do that.
English Teacher: Let's move on to the feedback comment...You used an alternative expression for the yes/no question, which was natural and meaningful. Put more stress on the word "do" in your first answer.
