Answer:

Here's the explanation of perfect, past, and future perfect tense including the passive form of each tense.

Present perfect tense

Present perfect tense is a tense which is used to indicate an action which has completely done at an unspecific time before now.

Sentence structure:

(+) S + has / have + V3 + O

(-) S + has / have + not + V3 + O

(?) has / have + S + V3 + O + ?

Example:

I have had breakfast

Past perfect tense

Past perfect tense is a tense which is used to indicate an action which had completely done before another action in the past.

Sentence structure:

(+) S + had + V3 + O

(-) S + had + not + V3 + O

(?) Had + S + V3 + O + ?

Future perfect tense

Future perfect tense is a tense which is used to indicate an action which will have completely done in the future.

Sentence structure:

(+) S + will + have + V3 + O

(-) S + will + not + have + V3 + O

(?) Will + S + have + V3 + O + ?

Example:

-PASSIVE VOICE-

Passive voice is a kind of sentence whose subject is the receiver of the verb’s action.

The general sentence structure of passive voice is:

O + to be + V3 + by + S

(Actually, the structure will be written as S + to be + V3 + by + O or S + modal aux + to be + V3 + by + O but I write it in this version so you can see the difference between active and passive voice)

Here's the structure of present, past, and future perfect tense in passive form.

Present perfect tense

(+) O + has / have + been + V3 + by + S

(-) O + has / have + not + been + V3 + by + S

(?) has / have + O + been + V3 + by + S + ?

Example:

Active: I have bought a new pair of shoes

Passive: A new pair of shoes has been bought by me.

Past perfect tense

(+) O + had + been + V3 + by + S

(-) O + had + not + been + V3 + by + S

(?) Had + O + been + V3 + by + S + ?

Example:

Active: I had finished the assignment

Passive: The assignment had been finished by me

Future perfect tense

(+) O + will + have + been + V3 + by + S

(-) O + will + not + have + been + V3 + by + S

(?) will + O + have + been + V3 + by + S + ?

Example:

Active: She will have eaten breakfast at 7 am tomorrow

Passive: Breakfast will have been eaten by me at 7 am tomorrow

I hope the answer is clear enough.
