imperative sentence

Learn About It

An imperative sentence gives a command. It usually end with a period, but it may also end with an exclamation point (!).

Commands ask or tell people to do something.

"Please pass the salt." is a command, that does not sound as commanding as, "Get out of my way!" But, both of these sentences are imperatives because they are both asking or telling someone to do something.

Finding the Subject

This may sound strange, but every single command has the same subject! Yikes! How is that even possible?

Well, since commands are always speaking to someone or something (you've got to address them if you're going to ask them to do something), the subject is always the word you.

You may have noticed, the word "you" is not even in a command. Because of this, the subject is actually called you understood, and it is written like this: (you)

This means that the subject is the word you, but since it is not written or spoken in the sentence, it is understood and is therefore in parentheses.

Present simple

   

Simple Present

FORM

[VERB] + s/es in third person

Examples:

You speak English.

Do you speak English?

You do not speak English.

USE 1 Repeated Actions

Use the Simple Present to express the idea that an action is repeated or usual. The action can be a habit, a hobby, a daily event, a scheduled event or something that often happens. It can also be something a person often forgets or usually does not do.

Examples:

I play tennis.

She does not play tennis.

Does he play tennis?

The train leaves every morning at 8 AM.

The train does not leave at 9 AM.

When does the train usually leave?

She always forgets her purse.

He never forgets his wallet.

Every twelve months, the Earth circles the Sun.

Does the Sun circle the Earth?

USE 2 Facts or Generalizations

The Simple Present can also indicate the speaker believes that a fact was true before, is true now, and will be true in the future. It is not important if the speaker is correct about the fact. It is also used to make generalizations about people or things.

Examples:

Cats like milk.

Birds do not like milk.

Do pigs like milk?

California is in America.

California is not in the United Kingdom.

Windows are made of glass.

Windows are not made of wood.

New York is a small city. It is not important that this fact is untrue.

USE 3 Scheduled Events in the Near Future

Speakers occasionally use Simple Present to talk about scheduled events in the near future. This is most commonly done when talking about public transportation, but it can be used with other scheduled events as well.

Examples:

The train leaves tonight at 6 PM.

The bus does not arrive at 11 AM, it arrives at 11 PM.

When do we board the plane?

The party starts at 8 o'clock.

When does class begin tomorrow?

USE 4 Now (Non-Continuous Verbs)

Speakers sometimes use the Simple Present to express the idea that an action is happening or is not happening now. This can only be done with Non-Continuous Verbs and certain Mixed Verbs.

Examples:

I am here now.

She is not here now.

He needs help right now.

He does not need help now.

He has his passport in his hand.

Do you have your passport with you?

Preposition

The Preposition

Recognize a preposition when you see one.

Prepositions are the words that indicate location. Usually, prepositions show this location in the physical world. Check out the three examples below:

On, in, and beside are all prepositions. They are showing where the puppy is. Prepositions can also show location in time. Read the next three examples:

At midnight, Jill craved mashed potatoes with grape jelly.

In the spring, I always vow to plant tomatoes but end up buying them at the supermarket.

During the marathon, Iggy's legs complained with sharp pains shooting up his thighs.

At midnight, in the spring, and during the marathon all show location in time.

Because there are so many possible locations, there are quite a few prepositions. Below is the complete list.

about, above, according to, across, after, against, along, along with, among, apart from, around
as, as for, at, because of, before, behind, below, beneath, beside, between, beyond, but*
by, by means of, concerning, despite, down, during, except, except for, excepting, for, from
in, in addition to, in back of, in case of, in front of, in place of, inside, in spite of, instead of
into, like, near, next, of, off, on, onto, on top of, out, out of, outside, over, past, regarding
round, since, through, throughout, till, to, toward, under, underneath, unlike, until, up, upon
up to, with, within, without

* But is very seldom a preposition. When it is used as a preposition, but means the same as except—Everyone ate frog legs but Jamie. But usually functions as a coordinating conjunction.

Understand how to form a prepositional phrase.

Prepositions generally introduce prepositional phrases. Prepositional phrases look like this:

PREPOSITION +OPTIONAL +NOUN,PRONOUN,OR GERUND n

Here are some examples:

At school

At = preposition; school = noun.

According to us

According to = preposition; us = pronoun.

By chewing

By = preposition; chewing = gerund.

Under the stove

Under = preposition; the = modifier; stove = noun.

In the crumb-filled, rumpled sheets

In = preposition; the, crumb-filled, rumpled = modifiers; sheets = noun.

Realize that some prepositions also function as subordinate conjunctions.

Some prepositions also function as subordinate conjunctions. These prepositions are after, as, before, since, and until. A subordinate conjunction will have both a subject and a verb following it, forming a subordinate clause.

Look at these examples:

After Sam and Esmerelda kissed goodnight

After = subordinate conjunction; Sam, Esmerelda = subjects; kissed = verb.

As Jerome buckled on the parachute

As = subordinate conjunction; Jerome = subject; buckled = verb.

Before I eat these frog legs

Before = subordinate conjunction; I = subject; eat = verb.

Since we have enjoyed the squid eyeball stew

Since = subordinate conjunction; we = subject; have enjoyed = verb.

Until your hiccups stop

Until = subordinate conjunction; hiccups = subject; stop = verb.

If you find a noun [with or without modifiers] following one of these five prepositions, then all you have is a prepositional phrase. Look at these examples:

After the killer calculus test

After = preposition; the, killer, calculus = modifiers; test = noun.

As a good parent

As = preposition; a, good = modifiers; parent = noun.

Before dinner

Before = preposition; dinner = noun.

Since the breakup

Since = preposition; the = modifier; breakup = noun.

Until midnight

Until = preposition; midnight = noun.
