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: Is the internet very important to you?
Darby Laai: For sure yeah.
English Teacher: Why?
Darby Laai: A couple of reasons. First, I use the internet to communicate with people that I work with, so I need things like email and instant messaging to get my job done. And uhhh...in addition to that there are many things I can learn from all kinds of websites on the internet.

English Teacher: When did you first learn to use the internet?
Darby Laai: After university.
English Teacher: Why?
Darby Laai: Because we didn't have widespread access to the internet in university. As a result, I did things the old school way. I thought about them and researched books and journals in print. And I had actual real discussions with my friends. Most young people these days just give up if they can't find it on the internet. Actually, they do find stuff on the internet, but they don't know how to separate the sheep from the goats...you know what I mean?

English Teacher: Hang on...what do you mean? I consider myself a young person.
Darby Laai: Ahh...I mean they don't know how to eat the fish and spit out the bones.
English Teacher: Well... let's discuss this later.
Darby Laai: Always later. Just like the Straw Lady. Ok...what's your next question teacher? 

English Teacher: Ok, well let's skip down to the last question. When was the last time you accessed the internet?

Darby Laai: I think it had to have been this morning. 

English Teacher: Why?

Darby Laai: Because I had to check out where this class was going to be and what time it was going to be at. Oh no, I used just "because" again.
English Teacher: It's fine...would you like to try this last question again? What's a different way to say "because".

Darby Laai: I think it's due to the fact that...
English Teacher: Right...but in this situation, I don't think that one sounds natural. But you did use a very nice combination in your first reason when you started with "A couple of reasons". Just be patient and you will begin to hear when alternatives to "because" sound natural or not.
Darby Laai: Ok I see..
