Blessed day,
I am here to ask for admission to this boarding school.
I find myself a capable student and I hope to get into this school.
Yours sincerely
The italics aren't showing up here, but assuming that it is the word "May" that is in question, the answer would be "interrogative". This is generally true whenever a question is used.
When giving a speech, you can resort to different techniques to emphasize an idea or topic. For example, use repetition; you can state your point, make a stop and rephrase the idea, you can slow down your voice to a point you want to emphasize (raise your voice for the point you want to highlight). Another good idea is to use body language, gestures while speaking to create a visual impact, too.
