How do I conjugate the Spanish passive voice?

Can I conjugate the passive voice in any tense other than the present?

The two most common ways to conjugate the Spanish passive tense are: the passive se (se publicó el libro) and the passive with ser (el libro fue publicado). Below you will find the passive voice conjugated in third person indicative:

TENSE	EXAMPLES	TRANSLATION
Present	es publicado / se publica	is published
Imperfect	era publicado / se publicaba	it used to be published
Preterite	Fue publicado / se publicó	it was published
Future	será publicado / se publicará	it will be published
Conditional	sería publicado / se publicaría	it would be published
Perfect	ha sido publicado / se ha publicado	it has been published
Pluperfect	había sido publicado / se había publicado	it had been published
Future Perfect	habrá sido publicado / se habrá publicado	it will have been published
Conditional Perfect	habría sido publicado / se habría publicado	it would have been published

When using the passive ser, keep in mind that the participle must agree in number and gender with the subject of ser.

Also, there exists a passive continuous form of ser (estar siendo publicado / está publicandose, etc.), but it is not very common.

Further more in the passive voice, 'estar' corrpesonds to perfect of ser:

Estar	Haber sido
Está	Ha sido
Estaba	Había sido
Estará	Habrá sido
Estaría	Habría sido

 

Translate the following sentences, writing in the form: ser passive / passive se.  Although capitalization does not count, spelling and order of the answer does! Assume that gender is masculine.
