The structure of a good mini-presentation:

I.       Introduction: one or two sentences. No need to be very long.

There are two ways of starting the question in BEC III “how to…’ and ‘the importance of…’，and BEC II questions always start with ‘what is important when doing something’

So, for ‘how to…’, you can always start with ‘Well, when it comes to xxing…, quite a number of things can be done.’ or  ‘ Well, as is known to all, it is very important to…The question is of course – how?’

For ‘ the importance of…’, you can start with ‘Well, in my view, you should not underestimate the importance of …’ or  ‘Well, as is known to all, it is very important to…The question is of course – why?’

For BEC II, you can start with ‘Well, when it comes to xxing…, several vital factors must be taken into account. ‘ or ‘Well, as we all know, many factors must be considered when…, the questions is of course – which ones?’

Basically, ‘how to…’ asks about methods, ‘the importance of…’ asks about benefits, and ‘what is important when…’ asks about factors to consider.
