Ielts speaking--how to improve your bandscore

Chapter Two:
Giving reasons and examples to support
the answer (part 1)
How do reasons and examples help you come up with a good answer in part
1?
One sentence wouldn’t be enough to answer any part 1 question. There is always
a need to expound or discuss, albeit concisely and straightforwardly.
There is also an aim to sound natural in IELTS Speaking, so it would help if
there are real-life examples or relevant discussions which you could use.
Finally, one must not forget that IELTS is an English proficiency test, so there’s
a need to show off the relevant skills. It would be advantageous if the candidate
can express these well in an answer of considerable length.
This is an opportunity for candidates to make use of learned expressions
(showing use of complex and appropriate grammar) and drop them naturally into
your speaking.
