Passive Voice, structure and tenses

You can use the Passive Voice in all English tenses using the following structure:

Object (receiving the action) + Verb BE + PAST PARTICIPLE + by + subject (doing the action)

E.g. The blog was written by the students.

In this example you can see that our intention is to give more focus and emphasizes in the object (the blog) and not who are doing the action (the students). Sometimes, when is known who is doing the action or you do not mention it you can skip that part of the structure.

The blog was written (you know that it was doing for the students).

As I told you we can use the Passive Voice in all tenses and it will depend the context or the situation that you are talking. In the next chart you will find some examples about Passive Voice in all Verb Tenses:
