When we express our ideas, we sometimes have a choice between the active voice and the passive voice.
Peter built the house. (Active)
The house was built by Peter. (Passive)
Most of my students are aware of the passive even if they don't realise it! Passive and active voices are probably used in most languages and are certainly used in German, the language that most of my students speak.
In German the passive is formed using the verb werden + past participle whereas in English we form the passive using to be + past participle.
The difficult thing to do in English is to choose the correct form of the auxiliary verb (to be). In order to do this, the following things must be considered:
Time - past, present or future
Aspect - simple, continuous or perfect
Plural or singular noun
3rd person or not
Over time, these choices become easier to make. For now, I'll give you some example sentences to help you make the right choice. Remember that software is an uncountable noun so is followed by a singular verb.
I confirmed that the software had been installed.
The software was installed yesterday,
The software was being installed all day yesterday.
The software is installed by Peter.
The software is being installed now.
The software has been installed.
The software will be installed.
The software will be being installed. (This sentence sounds odd.)
The software will have been installed by the end of the day.
