[ Edit this paragraph] Chinese imperative sentences expressing various meanings

An imperative sentence is a sentence with imperative mood that tells the other party to do or not to do something.

(1) intonation characteristics of imperative sentences

1. Phonetic intensity is generally heavier than declarative sentences, which are indicated by exclamation marks in writing.

2. With falling tone at the end of the sentence, the speed of several syllables in the second half of a longer sentence is accelerated.

(2) modal particles of imperative sentences

imperative sentences are mainly expressed by mood, and sometimes they are expressed by modal particles "ba, ah (ya, wow, where)". For example,

find a stool and sit down!

let him go!

hurry up!

come here, everyone!

you must work hard!

(III) Types of imperative sentences

According to the pragmatic meaning and tone of imperative sentences, imperative sentences can be divided into four categories:

1. Imperative sentences indicating orders

Imperative sentences indicating orders are mandatory, requiring the other party to obey, with positive words and serious attitude. For example:

Stop!

stand up!

let him in!

go and put out the fire!

2. The imperative sentence indicating the request

Compared with the imperative sentence indicating the command, the imperative sentence indicating the request should be more relaxed, and the modal particle "ba, ah" can be used, and the subject may or may not appear.

For example:

Please give us more comments!

please sit down!

answer this question!

help me!

3. Imperative sentences indicating prohibition

Imperative sentences indicating prohibition clearly indicate that the other party is forbidden to do anything, with strong words and firm attitude, without modal particles.

For example:

Don't move!

don't talk nonsense!

smoking is not allowed here!

don't go!

no one should talk casually!

4. Imperative sentences expressing dissuasion

Imperative sentences expressing dissuasion have a gentle tone, and the modal particle "ba, ah" is commonly used.

For example,

Listen to the teacher!

you guys have a rest!

let's all talk less!

don't make fun of him!

English imperative sentence

Definition: Sentences used to express commands, requests, advice, warnings, prohibitions, etc. are called imperative sentences. Imperative sentences are most commonly 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 a period is used at the end of the sentence to indicate the end. Example:

Go and wash your hands.

(Go and wash your hands. -command)

Be quiet, please. (Please be quiet.)

(Please be quiet. -request)

Be kind to our sister.

(Be kind to sisters. -advice)

Watch your steps.

(walk carefully. -warning)

Look out! Danger！

(look out! Danger! -a strong warning, like an exclamation)

Keep off the grass.

(Don't mow the lawn. -no parking.

No parking.

imperative sentences often express the subject "You" to make the other person sound softer, for example:

You go and tell him, Chris. (Chris, you tell him. )

Second, related passwords

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

the verb prototype predicate is when, and don't negative change is added at the beginning of the sentence;

reading aloud should be in a falling tone, and the exclamation point is always marked at the end of the sentence.

Third, the form of expression

● Affirmative structure:

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

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

● Negative structure:

1. Do-type and Be-type negative expressions are formed by adding don't at the beginning of the sentence. Such as: Don't 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: "Don't+Let+object+verb prototype+other components" and "let+object+not+verb prototype+other components". Don't let him go./Let him not go. Don't let him go.

An imperative sentence headed by "let"

An imperative sentence headed by "let" is a common verb sentence pattern, and its main uses are as follows:

1.

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

(1) let me try.

(2) let's do it.

(3) let me go and look for it.

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

(4) A. Don't disturb him.

B. Let's not disturb him.

(A) is a direct command, and its tone is strong, so it is not as gentle as (B).

2. It means "indirect command" or "wish".

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

(5) Let Robert take charge of the marketing department.

(6) Let her join our choice.

3. It means "warning", "contempt" and "threat".

The object in this imperative sentence is also dominated by the third person. In addition to his fierce tone, he sometimes speaks sarcastically. Such as:

(7) Let him try and he will expose his invisibility to work on his own.

(8) Let the invaders come and our armed forces will wipe them out in no time.

When using the imperative sentence of "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, Then use "Let......not" (see example (1)):

(9) Don't let this type of things happen again.

(1). It's raining now. Let's not go out until after the rain. < P > Second, "let" is only applicable to the present tense and can have the passive voice. Such as:

(11) Let the recurrent crimes be sent to prison.

(12) Let all the specialized capable staff be promoted.

III, "Let" can be followed by The infinitive without"to "and some appropriate adverbs, such as out, in, down, Alone et al.:

(13) Let the puppy out.

(14) Open the Windows and Let the Fresh Air in.

(15) The room is too sunny. Let the blinds down.

(16) Let me alone, please.

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

(17) Let's try it, shall we?

(18) Let us do it by ourselves, will you?

from "shall we" in (17) and "will you" in (18), it is not difficult to know that the former includes the hearer, while the latter does not. Imperative sentences express requests, orders, suggestions and so on. Predicate verbs are always in the original form. There is usually no subject in a sentence, an exclamation point or a period at the end of the sentence, and a falling tone.
