Present Perfect

The present perfect of to be uses  to have and the past participle been :

Subject Pronoun	Present Perfect of "To Be"
I / You / We / They	have been
He / She / It	has been

We use this tense when we need to:

Uses of the Present Perfect "To Be"	Example Sentences

Talk about multiple occurrences of a state or condition over time	He has been happy since he started his new job.
	The children have been excited about the upcoming trip.

Past Perfect

The past perfect of to be is super simple. It uses  had been in every person, whether singular or plural.

Use this tense when you want to:

Uses of the Past Perfect "To Be"	Example Sentences
Talk about situations and events that happened before other past events	I had been a teacher for 20 years when I retired.
	He had been there for three hours before his girlfriend arrived.
Describe people, objects and places in the past	It had been a very beautiful place in the past, but the house looked completely abandoned.
	The old man had been really busy all morning. When his family arrived, he was already tired.
Say that something had not happened before but now it has	I had never been to London before. (This means you are in London at the moment or you just came back from there.)
	John had never been in love until he met Silvia.   (This means he actually fell in love with Silvia when they met, but was never in love before that.)

Let’s compare that last use of the past perfect with the present perfect:

Present Perfect	Past Perfect
I have never been to Puerto Rico. (Still, to this day, I have not traveled there.)	I had never been to Puerto Rico before. (The speaker has now been to Puerto Rico.)
Mary has never been married. (She is not married.)	Mary had never been married before.   (She is now married for the first time.)

If the present perfect is used to say that you haven’t been to a place or something hasn’t happened yet, the past perfect is not necessarily a past-before-past event or description. This tense just tells us that the present perfect sentence is no longer true. The situation has changed, and we have now been to that place or the situation is now real.

Future Simple

The future simple of to be is another very easy tense to learn because it uses  will be in every person, no matter if it’s singular or plural.

We use the future simple to:

Uses of the Future Simple "To Be"	Example Sentences
Talk about age and professions in the future	He will be 18 next month.
	I will be a firefighter when I grow up.
Predict how something or someone will look or feel in the future	It will be the tallest building in the city when it is finished.
	He will be very happy there.
Say someone will be somewhere in the future	I will be at school at eight.
	She will be home soon.

Negative Forms of “To Be”

To form negative statements for to be verbs, all you have to do is add the word not . If you’re dealing with the past and present simple tenses, just pop it at the end of the to be verb. For the future simple, put it between “will” and “be.”

Present Simple	Past Simple	Future Simple
I am not a student.	I was not there yesterday.	I will not be here tomorrow.
You are not from Poland.	You were not very nice to Martha.	You will not be happy there.

We are not friends.	We were not students at the time.	We will not be at the cinema by then.
They are not doctors.	They were not so tall last year.	They will not be surprised.

If you’re dealing with the continuous/progressive and perfect tenses, write “not” between the to be verb and “being” or “been.”

Present Continuous	Past Continuous
I am not being silly.	I was not being rude.
You are not being yourself!	You were not being yourself.
He is not being naughty. She is not being naughty. It is not being naughty.	He was not being helpful. She was not being helpful. It was not being helpful.

By the way, it’s perfectly acceptable to shorten both negative and affirmative/positive statements (i.e., statements that don’t use “not”) using contractions. For more on those, read this post:

Question Forms of “To Be”

To create questions based on to be verbs, just switch the subject and the to be verb. This applies to the present simple and past simple tenses. For the future simple, put the subject between “will” and “be.”

Is he old? Is she old? Is it old?	Was he from Peru? Was she from Peru? Was it from Peru?	Will he be in London by Monday? Will she be in London by Monday? Will it be in London by Monday?

Special Forms of “To Be”: Beyond the Tenses

You now know the main to be tenses and how they are used. But there’s so much more to learn about this verb!

The following “specials” are situations in which the verb to be is used in specific ways.

Stative vs. Dynamic Forms

The verb to be is not seen in its continuous form (-ing ending) very often. When it is seen, it gets some very specific meanings.

Let’s take this sentence:

Anna is very helpful.

We have a sentence in the present simple, which means we are describing Anna. She is always helpful, and that is her nature. This is what we call a stative form of the verb to be.

Now have a look at the same sentence, but in the present continuous:

Anna is being very helpful.

All of a sudden, Anna is not a helpful person all the time, just this time. Today she is helping, but she normally doesn’t. This is the dynamic form of the verb.

We can also use the distinction between stative/dynamic forms when we want to complain about someone or something:

Example Sentence	Type of Verb	Explanation
Peter talks too much.	Stative	This is a description or a statement.
Peter is talking too much.	Dynamic	This is a complaint. He is being too talkative today.

Question Tags

Question tags are little “tails” added at the end of a sentence. They have the form of a question, and are normally used when we’re looking for another person to give their opinion or agree with us.

If the main verb of a sentence is to be, the question tag will also include a form of this verb:

You are very happy here, aren’t you?

She isn’t pregnant, is she?

They were being silly, weren’t they?

“To Be” and Adverbs: Word Order

Simply put, adverbs are words that  modify (change) adjectives, verbs or other adverbs. They give information about place, time, manner and cause, among others.

As a rule, remember to add adverbs after the verb to be:

I am always happy.

She is never tired.

The house is still on sale.

Our neighbor is seldom home.

However, if there’s a participle in the sentence (being or been), you should add the adverb between the conjugated verb and the participle:

Mary has always been happy here.

They have never been here.

She is still being naughty!

Modal Verbs and the Passive Voice

This post doesn’t cover modal verbs in detail, but it’s worth mentioning that the verb to be can be added between a modal verb and the past participle of a verb:

These walls should be painted already.

It can’t be found anywhere.

In fact, sentences that include “a modal verb + be + a past participle” are passive sentences. Here are two more examples of the passive voice with be:

He should be punished.

John may be injured.

However, passive sentences don’t always need to include a modal verb, only the appropriate form of the verb to be:

He was being carried.

The house has been sold.

We were told not to talk too much.

The Imperative: “To Be” Commands

You may already know that we use the imperative mainly for commands and instructions.

What you may not know yet is that we can also use the verb to be for this. Have a look at some examples:

Be quiet! / Don’t be so noisy!

Be humble! / Don’t be so arrogant!

Be my girlfriend, please.

Don’t be silly!
