<1>Definition: Imperative sentences express requests, commands, suggestions, etc. Predicate verbs always use their base form. Usually there is no subject in the sentence, an exclamation mark or period is used at the end of the sentence, and it is read in a falling tone.

Note: Sometimes, in order to strengthen the tone, do can be added before the verb.

Do sit down. Please sit down. Do study hard. Be sure to study hard.

b. When expressing an imperative sentence in a polite tone, please can be added at the beginning or end of the sentence. However, if please is added at the end of the sentence, a comma "," must be added before please.
