Answer 1

Respuesta:

1- Is, was

2-

a. Is

b. Isn't

was

3- were

Explicación:

1- Is: usamos IS cuando el sujeto es SHE, HE O IT. En este caso, el sujeto sería IT. Es decír, a TODAY lo reemplazamos por dicho sujeto.

was: es el pasado del verbo to be (am-is-are)

Was lo usamos cuando el sujeto es (I-SHE-HE-IT)

Podemos darnos cuenta de que una oración es en Pasado o Presente con sus "palabras claves"

Pasado: Ago, this Morning, Last, etc...

Presente: Everyday, sometimes, etc...
