How to form passive sentences based on tense? 

Forming passive sentences involves changing the structure of a sentence so that the subject receives the action rather than performing it. The tense of the passive sentence will depend on the tense of the original active sentence. Here's a guide on how to form passive sentences based on tense:

Present Simple:

Active: She writes a letter.

Passive: A letter is written by her.

Past Simple:

Active: They built a house.

Passive: A house was built by them.

Future Simple:

Active: We will finish the project.

Passive: The project will be finished by us.

Present Continuous:

Active: He is painting a picture.

Passive: A picture is being painted by him.

Past Continuous:

Active: The workers were constructing the building.

Passive: The building was being constructed by the workers.

Future Continuous:

Active: They will be celebrating the festival.

Passive: The festival will be being celebrated by them.

Present Perfect:

Active: She has written a novel.

Passive: A novel has been written by her.

Past Perfect:

Active: They had already finished the assignment.

Passive: The assignment had already been finished by them.

Future Perfect:

Active: He will have completed the work by tomorrow.

Passive: The work will have been completed by him by tomorrow.

Present Perfect Continuous:

Active: They have been building a bridge.

Passive: A bridge has been being built by them.

Past Perfect Continuous:

Active: She had been cooking dinner.

Passive: Dinner had been being cooked by her.

Future Perfect Continuous:

Active: We will have been working on the project for two years.

Passive: The project will have been being worked on by us for two years.

Remember that not all sentences can be converted into passive voice, and in some cases, the meaning may change. Additionally, the use of the passive voice is often a stylistic choice, and not every sentence needs to be passive.

 Let's continue with a few more examples:

Present Simple (Negative):

Active: She doesn't clean the house.

Passive: The house isn't cleaned by her.

Past Simple (Negative):

Active: They didn't finish the project on time.

Passive: The project wasn't finished by them on time.

Future Simple (Negative):

Active: We won't publish the article.

Passive: The article won't be published by us.

Present Continuous (Negative):

Active: He isn't fixing the car.

Passive: The car isn't being fixed by him.

Past Continuous (Negative):

Active: The team wasn't playing well.

Passive: The game wasn't being played well by the team.

Future Continuous (Negative):

Active: They won't be studying tomorrow.

Passive: Studying won't be being done by them tomorrow.

Present Perfect (Negative):

Active: She hasn't written the report yet.

Passive: The report hasn't been written by her yet.

Past Perfect (Negative):

Active: They hadn't completed the task.

Passive: The task hadn't been completed by them.

Future Perfect (Negative):

Passive: The project hadn't been being worked on by her.

Future Perfect Continuous (Negative):

Active: We won't have been using the software for a year.

Passive: The software won't have been being used by us for a year.

Remember that forming passive sentences correctly involves understanding the appropriate use of auxiliary verbs (am, is, are, was, were, has been, have been, will be, etc.) and the past participle of the main verb. Additionally, practice and exposure to various examples will help you become more comfortable with using passive voice in different tenses.
