| 释义 | The vocativeThe imperative is often used with a vocative. This is where you mention a person’s name or some other way of identifying the person to whom a command or request is being addressed.The vocative can be a proper noun, the pronoun you, or a noun phrase. The vocative can come before or after the main clause.A vocative forms a part of many questions.David, come here!Come here, David.Hey, you, stop talking!
 A vocative is also combined with an interrogative clause to form a request.Peter, do you know where I put the DVD?Have you seen Chris recently, Jenny?
 When a vocative is used with an imperative clause, the sentence is usually a command.Tony, would you pass me the hammer?Could I speak to you privately for a minute, Sue?
 A command can also be phrased as a request.Sam, get off there!You, come back!
 A practical reason for using a vocative is to supply the missing but understood subject, so that the right person will understand the command or request, and act on it.Would you stop talking now, darling, and go to sleep.Would you get off there, please, Sam.
 Note the punctuation. There should be a comma between the vocative part of the clause and the remainder.  As part of a command, except for urgent warnings, the use of the vocative is considered rude or abrupt.  |
