Be in the present simple tense

Affirmative form

Construction: subject + be

  • I am
  • you are
  • he / she / it is
  • we are
  • you are
  • they are

The contracted form is very common (especially in the oral form):

  • I am → I’m
  • you are → you’re
  • he is → he’s
  • she is → she’s
  • it is → it’s
  • we are → we’re
  • you are → you’re
  • they are → they’re

Negative form

Simply add NOT after the verb:

  • I am not
  • you are not
  • he / she / it is not
  • we are not
  • you are not
  • they are not

The negative form can be contracted:

  • I am not → I’m not
  • he is not → he isn’t OR he’s not
  • you are not → you aren’t OR you’re not

Interrogative form

To ask a question, it’s simple: you have to reverse the subject and be. The verb Be is then placed at the beggining of the sentence:

  • am I making myself clear?
  • are you happy?
  • is he ok?
  • are we arrived yet?

Be in preterite (= past simple)

Affirmative form

  • I was
  • you were
  • he / she / it was
  • we were
  • you were

Be careful, there is no contracted form.

Negative form

  • I was not
  • you were not
  • he / she / it was not
  • we were not
  • you were not
  • they were not

The negative form can be contracted:

  • was not → wasn’t
  • were not → weren’t

Interrogative form

Just like the present, be is placed at the beginning of the sentence, but at the preterit tense (was or were):

  • was I?
  • were you?
  • was he / she / it?
  • were we?
  • were vou?
  • were they?

How to use the verb to be

In English, the verb BE can be either verb or auxiliary.

As a main verb:

With a name, to talk about a characteristic:

  • Sam is very tall.
  • My mother was a teacher.
  • This cake is very tasty.
  • The children were good.
  • Paul and his wife are from New York.
  • The flowers are on the table.

As an auxiliary:

To make the continuous form with -ing:

  • They are eating 
  • It had been raining for hours.

To do the passive voice:

  • It’s broken
  • This car was made in Japan.

REMEMBER!

Be is often used to translate’to have’:

To talk about a state:

  • I’m hungry / thirsty  → J’ai faim / soif 
  • I’m lucky → J’ai de la chance

To say the age of someone:

  • I’m 24. 
  • He is 17. 
  • She is my age. 

Be can be used to talk about the weather

  • It’s hot / it’s cold today. 

To talk about size:

  • She is the same height as her husband. 
  • He is 6 feet tall. 
  • How tall are you?  (NOT How high are you?)
  • That tree is about 20 metres high. 

⚠ to talk about weight, do not use to be but the verb weigh: He weighs 70 kilos. (He is 70 kilos. = ❌)

To indicate a distance:

  • It’s 5 km to the next town. 

⚠ There are often mistakes with Born

  • I was born (NOT: I am born)
  • He was born (NOT: He is born)
  • They were born (NOT: They are born)
