5. “be” in passive sentences

5. “be” in passive sentences

Maybe this discussion will be a little confusing or hard to be digested, but don't worry if you have understood about the function of “be” before continuous tense, that it wouldn’t be difficult.
Don’t ever try to forget that “ active sentence means the subjects do the action or the verb explain about what the person does; passive sentence means the subject received the action. what is subject in active sentence, now it is object in passive sentence or what is object in active sentence, now it is subject.
In passive sentence, if we include the subject we use preposition “by” to introduce the subject but remember it is now object. Look at the table below:


Present continuous tense (active)
I am buying an umbrella
He is drinking water
She is eating pizza
It is printing documents
We are making our bed
You are pushing a window
They are telling stories


Present continuous tense (passive)
an umbrella is being made by me
water is being drunk by him
pizza is being eaten by her
documents are being printed by it
our bed is being made by us
a window is being pushed by you
stories are being told by them

Past continuous tense(active)
I was buying an umbrella
He was drinking water
He was eating pizza
It was printing documents
We were making our beds
You were pushing a window
They were telling stories

Past continuous tense(passive)
an umbrella was being made by me
water was being drunk by him
pizza was being eaten
documents were being printed by it
our beds were being made by us
a window were being pushed by you
stories were being told by them

again and again, all negative sentences have their “not” after the be and the introgative sentences have their “be” before the subject . here are the formulas.

Positive: subject + be + being + past participle
Negative: subject + be + not + being + past participle
Interrogative: be + subject + being + past participle
