No presente:

You - Are 
He - Is 
She - Is

They - Are 

No passado: 

I - Was 
You - Were 
He - Was 
She - Was 
It - Was 
We - Were

No presente continuo:

She - Is "verbo+ing" 
It - Is "verbo+ing" 
We - Are "verbo+ing"

E no passado contínuo:

You - Were "verbo+ing" 
He - Was "verbo+ing" 
She - Was "verbo+ing" 
Is - Was "verbo+ing" 
We - Were "verbo+ing" 
You - Were "verbo+ing" 
They - Were "verbo+ing" 

Agora a estrutura da frase é diferente, 

NO PRESENTE É ASSIM: 

Afirmativa: Pronome + Verbo TO be + Complemento 
Negativa: Pronome + Verbo TO be + "Not" + Complemento 
Pergunta: Verbo TO be + Pronome + Complemento 

Exemplos: 

Afirmativa: You are beautifull 
Negativa: You are not ugly 
Pergunta: Is she nice? 

NO PASSADO É ASSIM: 

Afirmativa: Pronome + Verbo TO be + Complemento 
Negativa: Pronome + Verbo TO be + "Not" + Complemento 
Pergunta: Verbo TO be + Pronome + Complemento 

Exemplos: 

Afirmativa: She was so cute 
Negativa: You were not a good person 
Pegunta: Was I sad? 

NO PRESENTE CONTINUO É ASSIM: 

Afirmativa: Pronome + Verbo TO be no presente + Verbo no gerúndio + Complemento 
Negativa: Pronome + Verbo TO be no presente + "Not" + Verbo no gerúndio + Complemento 
Pergunta: Verbo TO be no presente + Pronome + Verbo no gerúndio + Complemento 

Exemplos: 

Afirmativa: I am doing a great job here 
Negativa: You are not doing anything 
Pergunta: Is she doing something? 

JÁ NO PASSADO CONTINUO É ASSIM: 

Afirmativa: Pronome + Verbo TO be no passado + Verbo no gerúndio + Complemento 
Negativa: Pronome + Verbo TO be no passado + "Not" + Verbo no gerúndio + Complemento 
Pegunta: Verbo TO be no passado + Pronome + Verbo no gerúndio + Complemento 

Exemplos: 

Afirmativa: I was doing nothing 
Negativa: You were working here 
Pergunta: Was she driving the car?
