Final answer:
A speaker should use a formal style when preparing a speech for the school's Parent Teacher Association to convey professionalism and seriousness. This includes using proper grammar, formal language, and avoiding slang or casual expressions.
Step-by-step explanation:
When preparing a speech for a school's Parent Teacher Association, a speaker should use a formal style. This is because the PTA is a professional and official organization that requires a level of seriousness and respect. The speaker should strive to use proper grammar, formal language, and avoid slang or casual expressions.
Using a formal style in a PTA speech will help convey the importance and professionalism of the organization and its activities. It will also create a sense of credibility and respect among the audience, which usually consists of parents, teachers, and school administrators.
For example, instead of saying 'Hey guys, I'm really excited to talk about the PTA events,' a speaker using a formal style would say 'Good evening, ladies and gentlemen. I am honored to have the opportunity to discuss the upcoming Parent Teacher Association events.'
