What are the common English imperative sentences?

Imperative sentence (imperative sentence)

Definition: sentences used to express orders, requests, suggestions, warnings, prohibitions, etc. Known as imperative sentences, they are most often used to express commands, so they are often called imperative sentences in school grammar.

Imperative sentences are usually omitted because the object (that is, the subject) is the second person. The verbs in imperative sentences are all simple present tense, and the end of the sentence is indicated by a period. Example:

Go wash your hands.

Go wash your hands. -command)

Be quiet,please. Please be quiet. )

Be quiet,please. -Request)

Be kind to our sister.

Be kind to your sisters. -Recommendation)

Watch your step.

Watch your step. -Warning)

Watch out! Danger!

(Be careful! Danger! -Strong warning, such as exclamation point)

Please don't trample on the lawn.

Don't mow the lawn. -Prohibited)

No parking.

(No parking. -Prohibited)

Imperative sentences usually express the subject "you" to make the other person sound softer, for example:

You tell him, Chris. Chris, you tell him. )

Second, the relevant password

Imperative sentences have no subject, and the subject you is often omitted;

The prototype of the verb is the predicate, so don't add negative changes at the beginning of the sentence;

Read aloud in a falling tone and mark the end of the sentence with an exclamation point.

Third, the form of expression.

● Front structure:

1.Do type (i.e. verb prototype (+object)+other components). Please sit down here. Please sit here.

Some imperative sentences can be omitted when the meaning is clear. This way, please Please go this way. This way, please

2.Be type (that is, Be+ predicative (noun or adjective)+other components). Be a good boy! Be a good boy!

3.Let type (that is, Let+ object+verb prototype+other components). Let me help you. Let me help you.

● Negative structure:

The negative expression of 1 Do and Be are both formed by adding don't at the beginning of a sentence. Such as: forget me! Don't forget me!

Don't be late for school! Don't be late for school!

2. There are two negative forms of "Let+ object+verb prototype+other components" and "let+object +not+ verb prototype+other components". Don't let him go. /Tell him not to go. Don't let him go.

An imperative sentence headed by "let"

The imperative sentence headed by "let" is a common verb sentence pattern, and its main usage is as follows:

1. means "suggestion".

The "let" in this sentence pattern is followed by the first person pronoun object, such as:

(1) Let me try.

(2) Do it.

(3) Let me look for it.

This sentence is euphemistic and more polite than the direct imperative sentence. Compare (4)a and (4)b:

Don't disturb him.

B.let's not disturb him.

(a) It is a direct order, and its tone is strong, so it is not as gentle as (b).

2. Express "indirect orders" or "wishes".

The verb object in this sentence is a third-person noun or pronoun, such as:

Put Robert in charge of the marketing department.

Let her join our choir.

3. Express "warning", "contempt" and "threat".

The object in this imperative sentence is also dominated by the third person. In addition to the intense tone, sometimes with irony, such as:

Let him have a try, and he will expose that he can't work independently.

Let the invaders come, and our armed forces will destroy them at once.

When using the imperative sentence "let", we must pay attention to the following points:

First, there are two negative sentences of "let". If the object is the third person, use "Don't let ……" (see Example (9)); If the object is the first person, use "Let......not" (see the example (10)):

Don't let this happen again.

(10) It's raining now. Let's not go out until after the rain.

Second, "Let" only applies to the present tense and can have passive voice, such as:

(1 1) Let the recalcitrant criminals go to prison.

(12) Promote all the dedicated and capable employees.

Third, "Let" is followed by an infinitive without "to", or it can be some appropriate adverbs, such as out, in, down, alone, etc.

(13) Let the puppy out.

Open the window and let in fresh air.

(15) sunlight in the room. Put down the blinds.

Please leave me alone.

Fourth, when using "Let's", it includes the object of the speaker; When using "Let us", it does not include the other party, such as:

(17) Let's try, shall we?

(18) Let's do it ourselves, shall we?

It is not difficult to know from "Will we" in (17) and "Will you" in (18) that the former includes the hearer and the latter does not.
