A. Study this example:
This house was built in 1930.
'Was built' is passive. Compare active and passive:
Somebody built this house (object) in 1930. (active)
This house (subject) was built in 1930. (passive)
We use an active verb to say what the subject does:
* My grandfather was a builder. He built this house in 1930.
* It's a big company. It employs two hundred people.
We use a passive verb to say what happens to the subject:
* This house is quite old. It was built in 1930.
* Two hundred people are employed by the company.
B. When we use the passive, who or what causes the action is often unknown or unimportant:
* A lot of money was stolen in the robbery. (somebody stole it but we don't know who)
* Is this room cleaned every day? (does somebody clean it?--it's not important who)
If we want to say who does or what causes the action, we use by...
* This house was built by my grandfather.
* Two hundred people are employed by the company.
C. The passive is be (is/was/have been etc.) + the past participle (done/cleaned/seen etc.):
(be) done (be) cleaned (be) seen (be) damaged (be) built etc.
For irregular past participles (done/known/seen etc.), see Appendix 1.
Study the active and passive forms of the present simple and past simple:
Present simple
active: clean(s)/see(s) etc.
Somebody cleans this every day.
passive: am/is/are cleaned/seen etc.
This room is cleaned every day.
* Many accidents are caused by careless driving.
* I'm not often invited to parties.
* How is this word pronounced?
Present simple
active: cleaned/saw etc.
Somebody cleaned this room yesterday.
passive: was/were cleaned/seen etc.
This room was cleaned yesterday.
* We were woken up by a loud noise during the night.
* 'Did you go to the party?' 'No, I wasn't invited.'
* How much money was stolen?
