In order to build your answers in Part 3, you need to generate more ideas and vocabulary for each topic.
Once again we will do this with a Mind Map.
You an see an example below where,
1) I take the main topic, in this case SPORT, and then write down the other sub-topics you may be asked about on this topic.
2) then for each sub-topic I have written down some key words, chunks, collocations or expressions.
Now over to you!
Practice talking to yourself (or with a partner) about these subtopics, using if possible some of the expressions you have.
Finally, go back to the original Part 3 questions below and give a new answer, different from the first one you gave.
It is really important to give a new answer, not just the same one as before, in order to build flexibility.
Time yourself and try to speak for around 30 - 50 seconds.
You can record your voice, if you like, and then listen back later.
