verbo to be
El verbo TO BE es uno de los verbos más importantes del idioma Ingles, si acaso no el más importante, que interviene en numerosas estructuras verbales, muchas de las cuales difieren de las que utilizamos en castellano para expresar una idea.
Básicamente el verbo TO BE significa SER o ESTAR de acuerdo al contexto donde se emplee. Sus formas para el Simple Present se reducen a tres que son AM, ARE y IS , y para el Simple Past, a dos: WAS y WERE, usandose con los pronombres de la conjugación de la siguiente forma:
You He
I AM / WAS We ARE / WERE She IS / WAS
They It
Para efecto de construir oraciones interrogativas, sencillamente se coloca el verbo TO BE en primer término seguido por el sujeto de la oración y el resto de esta.
Am I a scientist? Is It a good project?
Was I a scientist? Was It a good project?
Is he in his office? Is she hungry?
Was he in his office? Was she hungry?
Are they psychologists? Are we twenty years old?
Were they psychologists? Were we twenty years old?
Las oraciones afirmativas se construyen de forma opuesta, colocando el sujeto de la oracíon seguido a continuación del verbo TO BE y el resto de la oración. Para formar la oración negativa, sencillamente agregamos el adverbio NOT despues del verbo en presente o pasado.
I am not a scientist / I was not a scientist
It is not a good project / It was not a good project
He is not in his office / He was not in his office
She is not hungry / She was not hungry
They are not psychologists / They were not psychologists
We are not twenty years old / We were not twenty years old
