Present Perfect Passive and Present Continuous Passive

Sentences can be active or passive. Therefore, tenses also have "active forms" and "passive forms." You must learn to recognize the difference to successfully speak English.

Active Form
In active sentences, the thing doing the action is the subject of the sentence and the thing receiving the action is the object. Most sentences are active.

[Thing doing action] + [verb] + [thing receiving action]

Examples:

Passive Form 
In passive sentences, the thing receiving the action is the subject of the sentence and the thing doing the action is optionally included near the end of the sentence. You can use the passive form if you think that the thing receiving the action is more important or should be emphasized. You can also use the passive form if you do not know who is doing the action or if you do not want to mention who is doing the action.

[Thing receiving action] + [be] + [past participle of verb] + [by] + [thing doing action]

Examples:



Present perfect passive:
Subject+ (has or have) + been + past participle

Examples:
Many tourists have visited that castle. (active voice)
That castle has been visited by many tourists.(passive voice)

Kerrie has paid the bill. (active voice) 
The bill has been paid. (passive voice)

Singular
Plural
have been given
We have been given
You have been given
You have been given
He has been given
She has been given
They have been given
It has been given

Most people use contractions: 
Singular
Plural
I've been given
We've been given
You've been given
You've been given
He's been given
She's been given
They've been given
It's been given

Present Continuous Passive
Let's take a look at how to make continuous passive sentences.
First of all, let's look an example active sentence:

'The workers are painting the bridge.'

In the above sentence:
The workers are the subject.
are painting is the present continuous verb.
the bridge is the object.

To make a present continuous passive sentence the object (the bridge) comes first:

'The bridge is being painted.'

This is how the present continuous passive is formed:

Object (The bridge) + 'to be' verb (is) + being + past participle (painted)

In passive sentences the subject is not always needed; however, if you want to include it the sentence becomes:

'The bridge is being painted by the workers.'

Let's take a look at some more examples:
'My car is being fixed.'
'The meeting is being held in my office.'
