What are imperative sentences in English?

Imperative sentences refer to sentences without subjects that express commands or suggestions.

1, imperative sentence has no subject. Sentences that omit the subject, usually imperative sentences.

2. The predicate verb at the beginning of a sentence must be the prototype of the action verb or the be verb. You cannot start with a modal verb.

3. The negative sentence of imperative sentence is to add Don directly before the prototype of the verb at the beginning of the sentence. And it must be an abbreviation, not a full name.

Imperative sentences express requests, orders, suggestions and so on. Predicate verbs always use the original form. Sentences generally have no subject, and there is an exclamation point or a period at the end of the sentence, falling tone.

First, the classification of imperative sentences

Imperative sentences express requests, orders, advice, invitations, suggestions, etc. Imperative sentences can be divided into two categories: second-person imperative sentences and three-person imperative sentences.

1. The second person said that imperative sentences are usually used to give orders, make demands or suggestions to the audience. The subject you of this imperative sentence usually does not mean, but begins with the prototype of the verb. For example:

Stand Up!

Don't worry!

But if there are many people present when you speak, you must express the subject or add a title to show who you are asking or giving orders to. For example:

Parents with children go ahead! Parents with children go to the front!

Mary cleans the windows and you boys wash the floor! Mary cleans the windows and you boys wash the floor!

Come on in, everybody! Everybody in!

Sometimes the subject is expressed to strengthen the tone or express emotions such as "unhappy", "bored" and "contempt". For example:

Don't be late again! Don't be late again!

You get out! Get out of here!

Mind your own business! Mind your own business!

2. The first and third person imperative sentences take the first and third person pronouns or nouns as the objects of the imperative sentences, and this kind of imperative sentences usually take let as the guide vocabulary. For example:

Let's go! Let's go home!

Tell him to get here before 10.

Imperative sentences can be expressed not only by predicate verbs, but also by nouns, adverbs and verb phrases. For example:

Help!

Be patient!

Hurry up!

hands up!

Second, the emphasis form and negative form of imperative sentences

The emphasis form of imperative sentences is to add do before the whole structure. For example:

Be careful!

Don't talk!

Please give my regards to your parents! Please remember me to your parents!

The negative form of imperative sentences is to add don't or never before the whole structure. For example:

Don't be nervous! Take it easy!

The negative form of imperative sentences with let as the leading word is generally not added after Let's or let us/me. For example:

Let's not waste time arguing about it! Let's not waste time arguing about it!

Let's not say anything! Let's not talk about this!

But British English also uses this expression: Don't say anything.

Thirdly, interrogative sentences in imperative sentences.

1. The interrogative part of the imperative sentence is affirmative, and shall and will should be used. For example:

Pass me the book, will you?

2.Let's is the first person imperative sentence, and the rhetorical question is "we will?" . For example:

Let's take a walk, shall we?

Let's forget it, shall we?

3. Let me and let us say imperative sentences on behalf of the second person. The interrogative sentence is "Will you?" . For example:

Let's take a walk, shall we?

4. Imperative sentences caused by other action verbs, whether their statements are negative or positive, often use "Will you?" A polite tone. For example:

Listen to me, okay?

Don't tell anyone about it, okay?

But sometimes "would you" is used after affirmative imperative sentences. "The table" Remind the other party to pay attention "or the table" Invite "is as follows:

Have a cup of coffee, will you?

Come in and sit down, will you?
