Imperative sentences starting with "let"

Started by "let "The leading imperative sentence (Imperative Sentences) is a common verb sentence pattern. It is mainly used in the following three ways:

1. Expresses "suggestion".

"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 with a strong tone, not as gentle and pleasant as (b).

2. Indicates "indirect command" or "wishes".

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

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

( 6) Let her join our choir.

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

The object in this imperative sentence is also the third person called the Lord. In addition to having a fierce tone, sometimes his words are sarcastic, such as:

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

(8) Let him try and he will expose his inability to work on his own.

(8) Let him try and he will expose his inability to work on his own. the invaders come and our armed forces will wipe them out in no time.

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

1. Negation of "let" There are two sentences.

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 example (10)) :

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

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

2. "Let" only applies to the present tense, and can have the passive voice (the passive voice), such as:

(11) Let the recalcitrant criminals be sent to prison.

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

3. In addition to the infinitive without "to" after "Let", It can also be some appropriate adverbs, such as out, in, down, alone, etc.:

(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.

4. When using "Let's", the speaker is included; when using "Let us", the other party is not included, 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 obedience Man, the latter does not. Imperative sentences express requests, commands, suggestions, etc. Predicate verbs always use their base form. Usually there is no subject in the sentence, an exclamation point or period is used at the end of the sentence, and a falling intonation is used.
