ABSTRACT
Imperative sentences indicate commands or requests, including ordering or advising someone (sometimes oneself) to do (not to do) something. An affirmative form orders or requests someone to do something and a negative form not to do something. It can be seen that an imperative sentence can be formed by a verb (phrase), adjective phrase, noun, or adverb. The imperative sentence formed by an adverb doesn’t occur frequently. Due to its function for commands and requests, it differs from the declarative sentence and the interrogative sentence in the aspects of form and structure. No matter for the affirmative or the negative form, verbs in the imperative sentence should be action verbs for people. The adjectives in a imperative sentence express two types of meaning which, in turn, decide the choice of adjectives. The stressed syllable at the end of the imperative sentence is usually pronounced with a falling tone. To be exact, how much it sounds euphemistic depends on its intonation.
