How to use ambiguous sentences

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. -no)

No eating or drinking.

(no eating or drinking.

No littering.

(No littering. -forbidden)

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

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

...

The imperative sentence headed by "let"

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

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.
