It would probably be best if in the context of the speech it is clear to the audience that the question is rhetorical. If that will be the case, then why not?
A question mark is a punctuation mark, not a part of speech. It is used at the end of a sentence to indicate that it is a question.
In indirect or reported speech, a question mark is not required at the end of a sentence that reports a question. Instead, a period is used.
Many people like to end a speech with a question, something the listener is left pondering. Some like to end a speech with a heavy and hard fact to sway the listener or reader to their side.
In the question "When will the meeting end?", the word "end" is a verb. It is the main verb in the sentence and indicates the action, which is the meeting concluding or finishing.
All three of the words at the end of the question sentence are "articles".
To transform direct speech into a question, you can invert the word order and add a question mark at the end. For example, changing "He said, 'Are you coming?'" into a question would be "Did he ask, 'Are you coming?'"
Not necessarily. You could use a rhetorical question (one which isn't supposed to be answered) which will immediately engage your listeners to your speech. You could then go back to the question at the end of your speech so that it appears to be "symmetrical" and finished.
you can end your speech like this:ice cream is yummy
One should end an impromptu speech with a joke that brings the speech back to the opening lines. In this way, the speech can come full circle and end on a high note.
I want to put the phrase "To all you smokers, screw you" at the end of the speech. Is that a good idea? ***** It depends on the venue and the audience. But, if you must query whether you should add the phrase, as in the question, then you should not.
You could end with a question, im not talking about "Do you like so and so?" use your imagination and my motto is "Think unique"
