Verbos sigulares y plurales

Para pasar los verbos del singular al plural al inglés no hay que cambiar nada, por ejemplo;

Presente simple: Se utiliza siempre el verbo en forma base excepto en la 3 persona del singular
I listen to music everyday. -------- We listen to the music everyday
She watches TV at night.---------------They watch TV at night.
Presente continuo: En este caso lo único que se cambia es el Verbo To be, pero el gerundio se deja igual:
I am writing a letter----------We are writing a letter.
He is waiting for his siter------------They are waiting for their sisters.

Presente Perfecto: Todas las formas son iguales excepto en la tercera persona del singular que se modifica el verbo have.
I have been to madrid----------------We have been to madrid.
She has gone to her house-----------------------They have gone to their house.

Pasado simple y perfecto: sigue igual.

En el pasado contínuo el plural se forma con were en vez de was
I was visiting my grandmother/ They were visiting their grandmothers.
